RE: double click issue in Firefox...

[Jorge Vásquez]

Thanks Adrian.  

Do I need to change the web.xml or add some specific taglib.xml
configuration file in order to use this component.  Sorry for asking more
questions but I really haven’t seen any link on the web detailing
installation of shale under a myfaces project.

1. Shale project has the idea to separate the different modules in the
different jar. So what you have to do is to download shale-core only and put
it in the web-inf\lib directory. For more info about the component see the
wiki [1] 

2. The solution will work on facelets too. And there are no performance
issue with that, but you should beware if you use ajax requests.

[1] http://wiki.apache.org/shale/Token 

2007/5/4, Jorge Vásquez <[EMAIL PROTECTED]>:

Thanks Adrian,

 

For option 1 I have the following doubt:

1.  What exactly are my requirements in order to use the s:token
component from shale, is there some documentation on this integration?  I
just want that component and nothing more from shale, is there like a
reduced library and simplified integration mechanism…I'd really like to
reduce my dependencies with other frameworks as much as possible.

For option 2 I have the following doubts:

1.  Does this solution that you posted work with Facelets too?
2.  Would there be some considerable performance issues on implementing
this approach?  I see that it affects all forms rendered on the application…

To prevent the double submit you could use a server side solution like the
token synchronizer pattern implemented as a shale component called s:token
from shale-core lib that you can get from here [1] or to implement it
yourself [2]

Regards to all,

During some testing I found that some unpredictable errors occur with
Firefox whenever a user clicks twice rapidly either on a commandLink or on a
commandButton.  What happens is that the respective method modifies some
internal state the first time but then when it gets executed again it founds
inconsistencies that cause an exception to be thrown.  Adding exception
controls to each method for this very specific scenario would result
terribly cumbersome, so I am writing to see if somebody out there has had a
similar problem and how have you managed to solve it.  I played the other
day for a while with JavaScript events but unfortunately those double click
events are uncontrollable when there's also the presence of onclick events,
since most of the time double clicks are also interpreted as simple clicks
and that turns out to be a huge chaos.  

I also tested this behaviour in IE7 (for which I must say that at last
Microsoft launched a descent browser) and there's no problem.  Apparently
this browser blocks double clicks.

Thanks in advance to anybody that could give me some advice…

unable to turn off log messages...

[Jorge Vásquez]

Regards,

I am having some problems with log messages in myfaces that I don’t know how
to stop making them appear.  I use log4J to control my log messages and even
when I configure it to stop getting all logger output messages I keep
getting the following:

howto stop getting message log: No Renderer found for component

[Jorge Vásquez]

Regards,

I am fine-tuning my JSF application and although it is working fine I keep
getting a log message in tomcat for a component that I Developed.

My component works fine, it is simply an alternative internationalization
tag.  

I created this component tag with the respective component handler and tag
handler.  I also registered the component in faces_config.xml with:

 

  

alerotech.InternationalLabel



 
com.alerotech.client.uicomponents.InternationalizerComponent



  

 

Nevertheless, I keep getting the same log message that is driving me nuts:

 

2007-04-11 11:19:09 StandardContext[/clientJSF]No Renderer found for
component {Component-Path : [Class: javax.faces.component.UIViewRoot,ViewId:
/pages/logon.xhtml][Class: javax.faces.component.html.HtmlForm,Id:
logonForm][Class:
com.alerotech.client.uicomponents.InternationalizerComponent,Id: _id27]}
(component-family=alerotech.InternationalLabel,
renderer-type=com.alerotech.client.InternationalLabel)

 

As you may imagine I use this tag almost thousands of times in my
application so you may get an idea of how many messages I have in the
logger.  

Any idea on what I am missing?

 

By the way I am using Facelets, in case it helps.

 

Thanks in advance,

JV

 

Confused with session issues...

[Jorge Vásquez]

Regards to all,

I’ve been working on an application with JSF for 6 months and we are
reaching the point when we need to do some optimization as there are lots of
objects in session scope and this has got us quite concerned.  I have been
going over the list’s past conversations regarding this subject but I
continue with 2 mayor questions:

1.  Is there any way to get an accurate estimation of the session size
without using serialization?

2.  Excessive Session use is discouraged, however components such as the
tree and results tables only work properly when backed up by session scoped
beans, I see some contradiction here and the savestate solution doesn’t work
for me as my application has multiple navigation paths between pages (no
real rules of the type origin -->destination can be applied)

 

Thanks,

issue with component ids

[Jorge Vásquez]

components inside a list.

I have tried the following 2 scenarios with the respective result:

 

1. 

   

 

   

   

   

 



 

RESULT:  I get the exception:  java.lang.IllegalArgumentException: component
identifier must not be a zero-length String
at
javax.faces.component.UIComponentBase.isIdValid(UIComponentBase.java:1034)
at
javax.faces.component.UIComponentBase.setId(UIComponentBase.java:274)

………etc…..

 




 

 

2. 

   

 

   

   

   

 



 

RESULT:  All the rendered anchor () elements in html end up having the
same id:  trialId

 




 

I need to be able to have each commandLink rendered with a specific Id as in
specific situations I reference certain commands through javascript
code…making use of their ids.

 

Any idea on how can I accomplish this?

 

Thanks and regards,

Tree2 lazy loading + expand path issues...

[Jorge Vásquez]

Regards to all,

I am working on a view which uses the same user interaction rules as Windows
Explorer.  The idea is that I have a tree on the left and a detail for that
tree on the right.  Both views need to maintain synchronized and as in
Windows explorer there’s the possibility of navigating into a folder both
from the tree panel or from the details panel.  So far I can handle very
good the scenarios whenever the user is navigating from the tree (this means
I can handle the detail view updates satisfactorily according to the node
clicked on the tree).  My problem is trying to update the tree view (go to a
specific node) whenever the user clicks on a folder item in the details
view.  My issue here is that I am using the lazy loading scheme described in
the wiki (Alternative Tree2 Lazy Loading Method...by jtmille3) and whenever
I send the path to expand to it doesn’t expands in the tree view.  I tried
the same scenario in a view that doesn’t use lazy loading and it works
perfectly, therefore my question is if someone can orient me on what would
be the right approach to allow tree node expansion but using lazy loading.
(There’s also one obvious point to note:  the node expansion as maximum
happens one level at a time and up/down the current selected node, ‘cause
otherwise I accept that it would be totally impossible).  

 

This is my code fragment for the prototype action that I am using:

 

public String expandNode() {

//Add the children under the node to expand first

TreeNode treeNode = _treeModel.getNodeById("0:0");

//Add the respective children in order to allow
expansion

AuthenticationBean authenticationBean =
(AuthenticationBean) FacesUtils

 
.getManagedBean("authenticationBean");

MessagesBean messagesBean = (MessagesBean)
FacesUtils.getManagedBean("messagesBean");

TreeNodeLazyLoading node000 = new
TreeNodeLazyLoading("actionNode", "0:0:0", "", "0:0:0", true, messagesBean

   .getLocalizedMessage("tree",
"workspaceOpenedIMG", authenticationBean

 
.getLanguageId()), messagesBean.getLocalizedMessage("tree",

   "workspaceClosedIMG",
authenticationBean.getLanguageId()));

TreeNodeLazyLoading node001 = new
TreeNodeLazyLoading("actionNode", "0:0:1", "", "0:0:1", true, messagesBean

   .getLocalizedMessage("tree",
"workspaceOpenedIMG", authenticationBean

 
.getLanguageId()), messagesBean.getLocalizedMessage("tree",

   "workspaceClosedIMG",
authenticationBean.getLanguageId()));   

treeNode.getChildren().add(node000);

treeNode.getChildren().add(node001);

String[] expandedPath = {"0", "0:0"};

_treeModel.getTreeState().expandPath(expandedPath);

return Constants.SUCCESS;

}   

 

Note:  The Action method “expandNode” above is attempting a hard-coded
expansion of the first child node and before invoking the node to expand it
adds two leaf nodes under the node to expand to assure that all its
descendants are already in the model.

 

If anybody can help me explain why the node isn’t expanding and guide me to
a possible implementation that enables the combination of lazy-loading with
one-level at a time node expansion-collapse similar to the way Windows
explorer operates I would deeply appreciate him/her…

 

Thanks,

Jorge Vasquez

RE: Tree2 parent node expand actions...

[Jorge Vásquez]

Thanks a lot Andrew.  One last question, the only alternative to getting the
nodeId is using binding or you know any other.  I am currently using too
much binding in my application and I am concerned whether this can cause
serious memory issues in some cases, for instance my tree is in session
scope so probably it wouldn’t be too ideal to include a binding in it, or
what do you think in relation to this subject?

Change the node contents to a commandLink with an updateActionListener and
in the "actionListener" method, toggle the expanded state of the node in the
tree state. Something like:









public class Bean {
  private UITreeData tree;
  private String activeNodePath;
  private TreeModel treeModel; 
  public UITreeData getTree() { return this.tree; }
  public void setTree(UITreeData tree) { this.tree = tree; }
  public TreeModel getTreeModel() { return this.treeModel; }
  public String getActiveNodePath() { return this.activeNodePath; }
  public void setActiveNodePath(String activeNodePath) { this.activeNodePath
= activeNodePath; }
  public void toggleNodeExpansion(ActionEvent evt) {
if (activeNodePath == null) return; 
 
treeModel.getTreeState().toggleExpanded(treeModel.getPathInformation(activeN
odePath));
  }
}

If you can get the node path (ie "0:1:2") without using the getNodeId
property then you can avoid using binding.

Table with grouping levels...

[Jorge Vásquez]

Regards to all,

I have a situation in which I need to paint a table that has a rendering
logic –typical of reports- in which there are several grouping levels.  Ex:
1 parent row with several child rows and so on.  I have looked at tree table
component but it doesn’t offer the presentation options that I am looking
for.  In the old application this was built with a couple of while loops
inside a jsp which where mixed with html tags.  How can I build such complex
html tables in jsf?  In my particular case I am using facelets which makes
things more difficult as I cannot use scriptlet.  This is one of those
complex rendering situations where I really miss scriptlet.  Has somebody
been into a similar case?  If so, which components have you used?  How can I
embed iterators into jsf?

Is the form on which this is occurring also your welcome file (index.jsf, or
some such thing)? I recently saw this "two clicks required" behavior in that
case. On first access, the URL would be http://myserver/myapp/. On the first
click, it would simply re-render with the complete URL
http://myserver/myapp/index.jsf. The second click then worked. 

When I changed my welcome file to index.html with a redirect to the jsf
page, this problem went away.

are necessary from an action button.

Asunto: SelectONeMenu valueChangeListener not skipping validation phase...

 

Regards,

I have a selectoneMenu component on my page and I want it to skip validation
phase when it changes, in the past somehow immediate="true" solved this
problem for me but now I have noticed that this ain´t working anymore.  

In my page I have:

< h:selectOneMenu id = "eclass" value = "#{nativeHandler.eclass}" class =
"dropdown" immediate = "true" 

 onchange = "submit()"
valueChangeListener = "#{nativeHandler.eClassSelected}" >

   < f:selectItems value =
"#{nativeHandler.eclassList}" />

 

 

And I have an input which is marked as "required" and whenever I change the
selectOneMenu option it displays the respective validation message for this
component, which I don´t want to happen.

 

Any ideas, is this a known issue, am I missing something?

 

Thanks,

JV

RE: SelectONeMenu valueChangeListener not skipping validation phase...

[Jorge Vásquez]

In that form where I have the selectoneMenu component, I have to click twice
over the button that does the submit of the form in order to effectively
process the action associated with that button.  The first time nothing
happens and then the action is finally executed.  Don´t know how to explain
this better…Its strange but its happening, if you want some source code I´ll
gladly submit it.  My workaround here has been to do the validation directly
on the action method, it works fine but kind of let me a feeling of
unsatisfaction.

Thanks,

Interest in knowing benefits of myfaces+shale

[Jorge Vásquez]

Hello,

I have been reading lately lots of answers that recommend an integration of
faces with shale but I really can´t imagine what specific benefits can this
bring to a project.  Is there some document or reference that anyone knows
that clearly illustrates this benefits, something like what can be done
adding shale that cannot be done with faces alone?

RE: Error using inputFileUpload component.

[Jorge Vásquez]

The cause of the error has nothing to do with the inputFileUpload component,
it is related with the SelectItems Iterator, please help me with this!!!  I
have no idea what is happening, I read that it was probably due to JVM
compatibility issues.  I am using JVM 1.4 and
myfaces-api-1.1.4-SNAPSHOT.jar, myfaces-impl-1.1.4-SNAPSHOT.jar,
tomahawk-1.1.5-SNAPSHOT.jar.

This must be a bug, what is the workaround for it?

Thanks,

RE: navigation pages history...

[Jorge Vásquez]

Sounds fine for me, I did the same thing and worked fine, I adopted the
Standard of naming actions with the same name as pages and this way I can
return directly the viewId to go to a previous page (Again this is possible
as I have no complex navigation cases).

Thanks a lot,

JV

JV,

 

Our app keeps a stack of views. The get the previous view pop the stack and
and push the current view on to it before you return,  We also have
standardized our navigation mechanism so that each action returns the name
of the view to navigate to next and our navigation.xml file maps full view
names returned from getViewId() to JSPs. If we have x JSPs there are x
 entities. So for us, returning the view from the top of
the stack will force the navigation handler to navigate to that view. Very
simple and easy to manage.

I’ve Still got one more question:

1.  I am using facelets and in facelets that method returns the name of
the page, which seems interesting, I need to somehow force a redirect to the
page returned and stored previously.  How can I force a redirect to a
specific page without using the traditional steps of returning an action
String and according to that action String and to the rules defined in
faces_config.xml let the faces Servlet do the forward.  Again, I want to do
an explicit forward from an action method to a specific page, how can I
accomplish this?

Its easy to create one. Just use a session scoped bean and add a stack to
it. You can get the last view rendered using the following

 

return FacesContext.getCurrentInstance().getViewRoot().getViewId();

RE: navigation pages history...

Gerald, can you be a little more detailed in this explanation please?
I'll begin a scenario to help clear out things.  I have the following rule
in faces_config.xml:



infoSpaceTool

/pages/tools/infospace/mainInfoSpace.xhtml




I have an action method that currently returns "infoSpaceTool" as String and
this causes JSF to load page: /pages/tools/infospace/mainInfoSpace.xhtml.
Now, what would happen when the navigation-case has a redirect element?

Thanks,
JV

Hi,

there is the -element in faces-config in order to do such a
forward. You can put it to any navigation rule. Should help in this
case.

RE: Accessing datascroller paginator variables

[Jorge Vásquez]

Hi list I noticed that the error had to do with the fact that the
HtmlDataScroller class was using the same logic for keeping track of the
rowIndex.
This is the implementation of the broadcast method:
   /**
 * Invoke any action listeners attached to this class.
 * 
 * After listener invocation, the associated UIData's properties get
 * updated:
 * 
 * if the user selected an absolute page# then setFirst is called
with
 * uiData.getRows() * pageNumber.
 * if the user selected the "first page" option then setFirst(0) is
called.
 * if the user selected the "previous page" option then setFirst is
decremented
 * by uiData.getRows().
 * if the user selected the "fast rewind" option then setFirst is
decremented
 * by uiData.getRows() * fastStep.
 * next, fast-forward and last options have the obvious effect.
 * 
 */
public void broadcast(FacesEvent event) throws AbortProcessingException
{
super.broadcast(event);

if (event instanceof ScrollerActionEvent)
{
ScrollerActionEvent scrollerEvent = (ScrollerActionEvent) event;

broadcastToActionListener(scrollerEvent);

// huh? getUIData never returns null.
UIData uiData = getUIData();
if (uiData == null)
{
return;
}

int pageindex = scrollerEvent.getPageIndex();
if (pageindex == -1)
{
String facet = scrollerEvent.getScrollerfacet();
if (FACET_FIRST.equals(facet))
{
uiData.setFirst(0);
}
else if (FACET_PREVIOUS.equals(facet))
{
int previous = uiData.getFirst() - uiData.getRows();
if (previous >= 0)
uiData.setFirst(previous);
}
else if (FACET_NEXT.equals(facet))
{
int next = uiData.getFirst() + uiData.getRows();
if (next < uiData.getRowCount())
uiData.setFirst(next);
}
else if (FACET_FAST_FORWARD.equals(facet))
{
int fastStep = getFastStep();
if (fastStep <= 0)
fastStep = 1;
int next = uiData.getFirst() + uiData.getRows() *
fastStep;
int rowcount = uiData.getRowCount();
if (next > rowcount)
next = (rowcount - 1) - ((rowcount - 1) %
uiData.getRows());
uiData.setFirst(next);
}
else if (FACET_FAST_REWIND.equals(facet))
{
int fastStep = getFastStep();
if (fastStep <= 0)
fastStep = 1;
int previous = uiData.getFirst() - uiData.getRows() *
fastStep;
if (previous < 0)
previous = 0;
uiData.setFirst(previous);
}
else if (FACET_LAST.equals(facet))
{
int rowcount = uiData.getRowCount();
int rows = uiData.getRows();
int delta = rowcount % rows;
int first = delta > 0 && delta < rows ? rowcount - delta
: rowcount - rows;
if (first >= 0)
{
uiData.setFirst(first);
}
else
{
uiData.setFirst(0);
}
}
}
else
{
int pageCount = getPageCount();
if (pageindex > pageCount)
{
pageindex = pageCount;
}
else if (pageindex <= 0)
{
pageindex = 1;
}
uiData.setFirst(uiData.getRows() * (pageindex - 1));
}
}
}


So for now what I had to do was change my local implementation of this
component.  Something that works perfect and I guess has no mayor
implications for others is changing the position of the invocation of
method:  broadcastToActionListener(scrollerEvent);  This way if somebody
wants to make use of the ScrollerActionEvent to keep track of the firstRow
Index this method won't overwrite his/her work.  I moved it to the last line
of the:
if (event instanceof ScrollerActionEvent)...code portion and it works
perfect  I think this sounds like a reasonable change to the
dataScroller component.

Asunto: Overwriting tomahawk component...

 

Regards,

I am requiring to change some behaviour in the datascroller component and I
have decided to overwrite it.  (Of course, I already tried out all the
possibilities it offered and didn´t found what I needed).

I am using facelets so first thing I changed was tomahawk.taglib.xml where I
added the following:

 

  

dataScroller



  

org.apache.myfaces.modified.HtmlDataScroller

  

  

org.apache.myfaces.modified.DataScroller

  



  

 

Next thing I did was I changed faces-config.xml and added the following:

 

  



  javax.faces.Panel

 
org.apache.myfaces.modified.DataScroller

  

 
com.alerotech.client.myfaces.custom.datascroller.ALTHtmlDataScrollerRenderer

  



  

 

  

 
org.apache.myfaces.modified.HtmlDataScroller

 
com.alerotech.client.myfaces.custom.ALTHtmlDataScroller



 

I am getting the following error:

 

javax.faces.FacesException: Undefined component type
org.apache.myfaces.modified.HtmlDataScroller

 

 

I don´t know what I am missing here, I have the respective classes:

com.alerotech.client.myfaces.custom.datascroller.ALTHtmlDataScrollerRenderer

and

Is there any known procedure to extend components?  What step am I missing?

RE: Accessing datascroller paginator variables

[Jorge Vásquez]

Jeff,
During tests I found an issue.  It only happens with the first page and when
the user clicks on the next page.  What happens is that the next page that
appears is page 3 (page 2 is skipped).  

I refined a bit my method letting it as follows: (I assume that the first
row has index 0):  

public void paginatorAction(ActionEvent event) {
ScrollerActionEvent scrollerAction = (ScrollerActionEvent)
event;
String clickedFacet = scrollerAction.getScrollerfacet();
int pageClicked = scrollerAction.getPageIndex();
//Means a facet was clicked
if (clickedFacet != null) {
if (clickedFacet.equals("next")) {
_rowIndex = _rowIndex + _rowsPerPage;
} else if (clickedFacet.equals("previous")) {
_rowIndex = _rowIndex - _rowsPerPage;
} else if (clickedFacet.equals("first")) {
_rowIndex = 0;
} else if (clickedFacet.equals("last")) {
_rowIndex = (_rowData.getRowCount() -
getLastPageRows());
} else if (clickedFacet.equals("fastr")) {
_rowIndex = (_rowIndex -
PAGINATOR_FAST_STEP*_rowsPerPage);
if (_rowIndex < 0) {
_rowIndex = 0;
}
} else if (clickedFacet.equals("fastf")) {
_rowIndex = (_rowIndex +
PAGINATOR_FAST_STEP*_rowsPerPage);
if (_rowIndex > (_rowData.getRowCount() -
getLastPageRows())) {
_rowIndex = (_rowData.getRowCount()
- getLastPageRows());
}
}
} else {
//Means a pageNumber was clicked
_rowIndex = (pageClicked*_rowsPerPage -
_rowsPerPage);
}
}

During debugging I check the value of rowIndex and it corresponds to the
first index of the second page but it skips that page and shows page 3.  Any
idea what is happening here?

Jorge Vásquez

Thanks JV,

If you have time, could you add a section about this approach to that 
wiki page? [1] I think this would be a great addition, as it certainly 
gives people more options.

We will need to come up with some intuitive section headings, separating 
the different approaches for clarity.

I think the most fundamental difference between our solutions is that 
mine revolves around the concept of marking or selecting a row. This 
marking is performed externally to the datascroller: through clicking a 
commandLink or executing some code in an action method. When the  user 
returns from another page, they will be shown the datatable page which 
includes the row they marked. (whether or not it's the last one they 
viewed)

Your solution allows the current dataScroller page to be persisted much 
more directly. When the user returns from another page, they will be 
shown the datatable page which they last viewed.

I think certainly that some users will prefer one solution, while others 
will have a use case that requires the other. Having both on that wiki 
would be great. Of course, we need to format it well and explain it so 
that people know what the differences are.

RE: Accessing datascroller paginator variables

[Jorge Vásquez]

Hi Jeff,
I found another approach to maintain the page the user is at.  I am using
the actionListener attribute of the dataScroller.
In my xhtml page I have the following:

*XHTML CODE PORTION*
























 


In the managed bean I have the following relevant code:

**MANAGED BEAN CODE PORTION*
private final static int DEFAULT_ROWS = 2;
private final static int PAGINATOR_MAX_PAGES = 5;
private final static int PAGINATOR_FAST_STEP = 5;
private int rowIndex = 0;
private int rowsPerPage = DEFAULT_ROWS; 

public void paginatorAction(ActionEvent event) {
ScrollerActionEvent scrollerAction = (ScrollerActionEvent)
event;
String clickedFacet = scrollerAction.getScrollerfacet();
int pageClicked = scrollerAction.getPageIndex();
//Means a facet was clicked
if (clickedFacet != null) {
if (clickedFacet.equals("next")) {
rowIndex = rowIndex + rowsPerPage;
} else if (clickedFacet.equals("previous")) {
rowIndex = rowIndex - rowsPerPage;
} else if (clickedFacet.equals("first")) {
rowIndex = 0;
} else if (clickedFacet.equals("last")) {
rowIndex = _rowData.getRowCount() -
rowsPerPage;
} else if (clickedFacet.equals("fastrewind")) {
rowIndex = rowIndex -
PAGINATOR_FAST_STEP*rowsPerPage;
if (rowIndex < 0) {
rowIndex = 0;
}
} else if (clickedFacet.equals("fastforward")) {
rowIndex = rowIndex +
PAGINATOR_FAST_STEP*rowsPerPage;
if (rowIndex >= _rowData.getRowCount()) {
rowIndex = _rowData.getRowCount() -
rowsPerPage;
}
}
} else {
//Means a pageNumber was clicked
rowIndex = pageClicked*rowsPerPage - rowsPerPage;
}
}

public int getRowIndex() {
return rowIndex;
}

public int getRowsPerPage() {
return SearchResultsBean.DEFAULT_ROWS;
}

public boolean isFirstPage() {
return (rowIndex < rowsPerPage);
}

public boolean isLastPage() {
return (rowIndex >=  (_rowData.getRowCount() - rowsPerPage));
}

public int getFastStep() {
return SearchResultsBean.PAGINATOR_FAST_STEP;
}

public int getPaginatorMaxPages() {
return SearchResultsBean.PAGINATOR_MAX_PAGES;
}



The most important method here is:  paginatorAction which captures all
scrollerActionEvents and according to the type of element clicked (either a
facet or a specific page) it displaces the rowIndex variable accordingly.  

Also, I added conditional rendering to the facets based on whether the user
is at the first or last page.  If the user is at the first page there´s no
need to include first, previous and fastrewind facets and if the user is at
the last page there´s no need to include last, next and fastforward facets.

I haven´t included anything yet in the wiki but if you guys think this can
be helpful information to others then let me know and I´ll add it to the
wiki.

JV

Hi list,

I am using dataScroller for paginating a list.  I would like to have access
to the current page in the bean in order to load it whenever a user returns
to a list that was previously loaded.  My scenario is the user is loading a
set of detail pages and when he/she comes back to the list it isn´t loading
the page that he/she was at prior to going to the detail pages.  So I was
thinking if I can keep the current page in the bean but continue using
datascroller since I don´t want to reimplement all the pagination logic that
this component already provides.

problem with session beans and request beans inheritance...

[Jorge Vásquez]

Hi guys,

In my application I have an inheritance model with managed beans in which
the root bean of the hierarchy is the only one that is in session scope and
all the state is kept in it.  The other beans just implement behaviour
methods and are stateless.   

My base bean is called:  InformationElementRootHandler and I have one class
named NativeHandler which extends from it.  InformationElementRootHandler
has an open method which NativeHandler inherits so when this method is
executed on NativeHandler the one that is executed is the one provided by
InformationElementRootHandler (so far, this is plain old inheritance
theory).  The strange thing that happens is that the open method initializes
some instance members of InformationElementRootHandler but afterwards when
another method of this bean is invoked the surprise is that the instance
members that were previously initialized have all null values, no idea why?


 

I would appreciate any insights to this problem.

Thanks and regards,

JV

RE: Appending dynamic table as column to datatable...

[Jorge Vásquez]

Simon,
But still don't you think that it would be nice to include a value attribute
as part of panelGrid and let that value reference a panelGrid instance.  It
can be similar to what  offers as value.  This is
pretty nice in cases where you don't want to maintain updating the model
object as you may do in the case of a binding but you just want to create
the object and associate it to a panelGrid just once...Anyway, my problem
continues,  what I am requiring is to be able to include a "code-generated"
table as a column in a datatable.  This table has to be only a row in size
but with a variable number of columns depending of each row´s specific
conditions.  Some rows may have some consecutive images, or a combination of
images and texts, or commandLinks, etc.  I tried using a binding but all my
rows get the same value which is the same as the first row.  I was thinking
of doing it with datatable but haven't came out with a clean solution since
the column types shouldn't be known at the xhtml page, there should be just
a mapping to a value on the bean and that value brings the whole datatable
object.  I don´t know if this is enough to make my point clear, the
requirement is probably too specialized but that's software
engineering, the technology is the media and the sole ruler is the customer.

JV

All "value bindings" on components ("value" is the most common name for 
such an attribute) reference a *model* object, not a component.

In the case of an h:dataTable for example the "value" attribute refers 
to a list of model objects to be rendered within the table, not a list 
of child components of the table.

An h:panelGrid may have child components, but it has no meaningful 
*model* object to refer to, so there is no "value" attribute on that 
component.

Simon

RE: Appending dynamic table as column to datatable...

[Jorge Vásquez]

Hi again,

 

I can simplify a little
bit my question:  “Has anybody generated a datatable dynamically”,
when I say dynamically I refer to building the whole table from java code in
the following manner:

 

    Application
app = FacesUtils.getFacesContext().getApplication();

    HtmlDataTable
myDataTable = (HtmlDataTable)
app.createComponent(HtmlDataTable.COMPONENT_TYPE);

…..

 

And associating it to a
page:

 

        <h:panelGroup rendered="#{columnHeader.internalTable}">

     <h:dataTable rows="1" value="#{searchResultsBean.columnValue.data}"
>

……..     

h:dataTable>

   
    h:panelGroup>

Hi to all,

I have a special requirement for a data table where
one column can correspond to a series of consecutive html elements that may
vary for each row (It can be thought in html terms as embedding a table for a td).
 I have decided to use a panelgrid for this special requirement but I
cannot use the binding attribute since I get an error during rendering, neither
can I use some value attribute which isn´t supported by panelgrids, etc. 
Has anybody had a similar requirement?  If so, how did you proceeded using
JSF?

RE: Help with datatable sorting...

[Jorge Vásquez]

Finally, after 8 hours of fighting with this I found the error, but yet I
haven´t been able to understand what was happening, although everything is
working properly now (Its probably a bug but I'm not sure).

I had the following input hidden elements in the page:


  

(where getText2 is a Facelet function that I use often throughout my
application for accesing some internationalization libraries that we use
with this project)

The goal of both of these hiddens is to interact with some javascript code
that I have to show specific confirm messages prior to delete actions.

This is really strange 'cause what causes the problem is the use of the
function, a:getText2, but the text gets rendered without problem and on the
page I get the respective:





As an experiment I included the inputHidden without a function and it works
perfectly.





IT’S A STRANGE WORLD!

did a couple of changes and its not working anymore (The worst of all is
that it isn´t under Version Control so I don´t have the previous working

empty ("") meanwhile in the other one it is the respective column name.

Hmm..actually, after reading that Working_with_auto_sortable_tables

it's a while since I last wrote a sortable table but I don't remember

Help with datatable sorting...

Regards to all,

One week ago I had my commandSortHeader working
perfectly until all of a sudden it just stopped ordering.  I haven´t done any
change neither to the xhtml page nor to the bean, and I am really having a
tough time trying to decipher how is this component´s operation in order to
proceed with some debugging.  This whole ordering stuff is really “sui-generis”,
‘cause it seems to work without the conventional action paradigm or at
least I don’t see nowhere where the action invocation takes place.  My
specific problem is that I am not receiving on the bean the column name clicked
by the user.  In summary I have 2 questions that can really help me solve this
issue:


 Why can´t the column
 be arriving at the sort function of the bean?  (This is probably too
 difficult to answer as it implies multiple possibilities)
 Can anyone explain
 me the basic operating mechanism used by the commandSortHeader component
 or redirect me to somewhere where it is explained?


 

An answer to any of the 2 questions would be deeply
appreciated.

1.  I created a listener that generated the components before the
Render Response but unfortunately the generated components weren´t bound to the
included page as the binding process in the included page took place during the
Render Response phase and not before.

2.  I decided to intercept somehow the binding process by
introducing a binding component for each included page that would act as a
trigger to the generation of the other components that were binded, but during
this process I discovered that the getters for a binding are only called once
in the history of that component and not for each cycle, and I was using a
binding getter as trigger.  I know this may sound quite confusing but my
current project´s nature is so complex to transmit these ideas just in one
email.

I think that my new idea is to able to reset some elements of the
component tree related to the included pages to permit the trigger getter to be
invoked always and in this way be able to generate the tree composition for the
included page again.  

 Again, my main issue to simplify more my question is being able to
clear specific parts of a component tree (this demands for me to know where is
this tree kept in order to clear specific elements that I wish).  Can
somebody give  help me with a brief example of jsf component tree
manipulation or at least suggest me which are the classes involved in this
process?








The root of the component tree can be retrieved like this:

    UIViewRoot root = FacesContext.getCurrentInstance
().getViewRoot();

>From there, you can walk the entire tree to find what you need, or perhaps use
the findComponent() method to locate a component based on its identifiers.

Low level myFaces component maniulation...

[Jorge Vásquez]

Regards,

I have run into a very complex situation due to the
fact that I use dynamic includes in my application.  I need to change the whole
component tree of an include and I have found that the bound components inside
an include are processed in the RenderResponse phase (In case it helps I use
myfaces combined with facelets).  So I have tried all the alternatives that you
can imagine:

1.  I created a listener that generated the
components before the Render Response but unfortunately the generated
components weren´t bound to the included page as the binding process in the
included page took place during the Render Response phase and not before.

2.  I decided to intercept somehow the binding
process by introducing a binding component for each included page that would
act as a trigger to the generation of the other components that were binded,

Asunto: Include Directive
Execution...



 

Regards to all,

 

I am using the include directive in xhtml to
dynamically load different pages inside a main page container with the
following syntax:

 



 

The idea is that I have a tree and according to the
node that is selected the page that is include should change (The tree executes
and action that modifies the page attribute in toolTabBean.currentTab).
 My problem is that I would like the page to be included somehow before
the request processing lifecycle begins ´cause I need to get the component
binding to be done with the new included page and not with the actual page.
 

 

I think that an answer to the following questions can
give me a hint as to how to proceed:

 


 In which part of the
 JSF lifecyle is the include directive executed?
 Is there any way to
 anticipate the page inclusion in order to process the bindings related to
 the included page?

RE: Problems with Calendar popup position.

[Jorge Vásquez]

Please somebody help me
with this,

I have detected the
source of the error but its _javascript_-related and to be honest I suck at
_javascript_.

 

The error takes place in
the file:  popupcalendar.js.

 

In the following lines (1324-1383):

 

    try

    {

    do {

    aTag =
aTag.offsetParent;

    leftpos += aTag.offsetLeft;

    toppos += aTag.offsetTop;

    }

    while (aTag.tagName != "BODY");

    }

    catch (ex)

    {

    // ignore

    }

….

 

Somehow the elements that
I have containing the img that activates the popup cause problems and the
offset ends up being greater, causing the popup to appear displaced to the left
and to the bottom.  

Is this a bug?  Has
anyone had a similar problem?  If so how have you solved it?

 

Cheers,

Asunto: HtmlRadioButton problem...



 

Hi everyone,

I am getting a strange behavior in the
htmlRadioRendering process.  The exception that I am getting is:

java.lang.IndexOutOfBoundsException: index 5 >= 5

  at
org.apache.myfaces.renderkit.html.ext.HtmlRadioRenderer.renderRadio(HtmlRadioRenderer.java:108)

 

After
going over the HtmlRadioRenderer code I have found that the cause of the error
is due to the fact that the index of the HtmlRadioButton element that is being
rendered is greater than the size of the HtmlSelectOneRadio list of elements
that is referenced by the HtmlRadio element.  I am generating the Html
Object model in java code and in the model that I generate the indexes are
always smaller than the size of the SelectOneRadio list of elements.  To
make things worse this error only appears occasionally after regenerating the
Html object model, but I haven´t been able to decipher the pattern that
originates the error since it is very random.  I have the feeling that
somehow the HtmlRadioRenderer occasionally does some cache on the
HtmlSelectOneRadio, and the size returned isn´t the size of the current
selectOneRadio list but of the previous one…

 

Unfortunately
for me I cannot have a definite decision since my debugging tool (Exadel
Studio) isn´t allowing me to debug the HtmlRadioRenderer at runtime during
execution in tomcat.  

Can
anybody help me with this?

// Create Facet Component

UIPanel panelComponent =
(UIPanel) … // create HtmlPanelGroup or whatever is the main child

// Add Facet to Parent

Very dynamic page definitions...

[Jorge Vásquez]

Regards,

I have a specific need with JSF to change some pages based
on runtime conditions.  For example, some users of the app would see a form
rendered on a two-column table meanwhile others may get it rendered totally different,
even with different field order, according to a personalized template used by them.
 I was thinking of using three scenarios for certain pages, and they would get
included according to runtime conditions of the current user, something like
this:

 



<ui:fragment rendered="#{searchTreeBean.scenario
== 0}>

  <ui:include src="/pages/standard.xhtml"
/>

ui:fragment>

 



<ui:fragment rendered="#{searchTreeBean.scenario
== 1}>

  <ui:include src="/pages/personalized.xhtml"
/>

ui:fragment>

 



<ui:fragment rendered="#{searchTreeBean.scenario
== 2}>

  <ui:include src="#{mybean.includedPage}"
/>

ui:fragment>

 

But I am not very sure if this is an adequate
strategy to support personalized pages for particular users, anyone has had a
similar problem?  How have you proceeded?  This has also lead me to think if
navigation conditions can be incorporated to the faces-config.xml file at
runtime?

RE: Problem with Spanish characters in myfaces simple examples

[Jorge Vásquez]

I don´t know if I didn´t made myself clear but first of all the encoding
used isn´t ASCII and there´s a .properties file for Spanish in the
myfaces-example-simple-1.1.5-SNAPSHOT named:  example_messages_es.properties
where there´s a localized Spanish text for each label.  I think that the
problem is either related with some configuration that is missing in the
faces-config that comes with the demo files, related to the locales
supported or it can also be related to some tomcat config variable, I
already restarted tomcat placing the following line at Catalina.bat:  
set CATALINA_OPTS=-Dfile.encoding=UTF-8, but the problem persists.  I found
a recommendation at:  http://wiki.apache.org/tomcat/Tomcat/UTF-8 but I think
that there would be no reason to add a filter, and it should work fine with
the encoding being set in each page and in the container but unfortunately
problems continue...
Again, any ideas?

I dont think by the way you've described is anything to do with JSF. 
Have a look at the following link. You'll need to replace these

tags will do this for you

For instance, instead of “país” I get:  “Pa�s”.  I am using firefox 1.5.0.6 with UTF-8 as

they also have Utf-8 encoding:  <%@ page session="false"

dynamic list rendered onmouseover event...

[Jorge Vásquez]

Regards to all,

I was wondering if anyone has developed or has used a
component which activates a lookup list when a user points his mouse over some
text (mouseover event).  I have seen something similar in gmail on the chat
that is integrated with the web client where  whenever one points to a contact
it shows some possible actions related to a contact based on the current
situation of the contact (whether he/she is logged, etc)…

In DHTML terms I think of it as a contextual menu
which activates with mouseover events and deactivates with onmouseout events.  I
have also seen something similar in some Microsoft applications where usually you
get a contextual combobox for each cell in a row once the user points his/her
mouse to the cell.  

 

Thanks in advance,

Jorge Vásquez

Hi, I forgot to include that part in the post, but of course I create the map
object.  The bean has session scope and its constructor includes the line:

returnCheckBoxesMap = new HashMap();

Problem with value-binding with map attribute...

[Jorge Vásquez]

Hi, 

I have some form elements mapped to the same map
attribute of a bean but with different keys each and in theory when a post is
done the map keys should each be set with the values entered in each element in
the form but the map always arrives empty.

 

In order to make myself clear here goes a simplified
example of what I am trying (by the way, the possibility of creating a direct
setter and getter for each property is not possible in my case which is a
little more complex than this example):

 

In the jsp I have something like the following:

 



 

Then, when I invoke an action method on the bean which
has the attribute and getter method:

 

        private Map returnCheckBoxesMap;

 

 

  public Map getReturnCheckBoxesMap() {

    return returnCheckBoxesMap;

  }

 

I notice that the returnCheckBoxesMap remains empty
without the values that I inputted on the textbox, I imagined that by doing the
mapping the map attribute is automatically updated with the values that are
sent on the page?  

Can anyone explain this to me?  How is the
value-binding process done with map attributes, is this a bug or am I missing
something?

 

Regards,

Jorge Vásquez

Thanks Grant,

One question though, your
decision on that Project was to keep a hybrid or to migrate everything to JSF?

hybrid



 

Jorge,

I have worked on a project which migrated from a PURE servlet environment to
JSF. We gradually moved the functionality from the servlets to JSF pages.
Overall the experience was not a bad one, as there are ways to access beans
from the servlets, and the request / session info in the servlets can be
reached from the JSF beans. 

Performance wise the servlets performed much better than the JSF pages, but we
could accept that. The fact that there was a combination of servlets and JSF
pages did not slow down either though.

Hope that helps. 

-Grant.

Hi,

Has anybody used a hybrid as an integration strategy with an old
application that uses the JSP Model 2 architecture (jsp + servlets with clean
separation of model, view and control).  In theory it should be possible
since the jsf architecture uses servlet mappings, so we can play with the URIs
sent by the legacy code and the new code in JSF but my curiosity is more aimed
at consulting if anyone of you has done something similar in your projects and
what have you concluded (complex to maintain?, performance issues?, etc.).

RE: HELP with h:selectOneRadio inside h:dataTable

[Jorge Vásquez]

FINALLY I MADE IT!!!,
In case someone is interested I finally was able to generate a table from
the bean with a select one radiobutton...
The first thing you have to do is generate the list of radiobuttons as
follows:
HtmlSelectOneRadio orderRadioButton = (HtmlSelectOneRadio)
app.createComponent(HtmlSelectOneRadio.COMPONENT_TYPE);
orderRadioButton.setId("ordenar");
orderRadioButton.setRendered(false);
UIComponent component =
FacesUtils.getFacesContext().getViewRoot().findComponent("fieldsForm");
for (int i = 0; i < dataFieldCollection.getCollCount();
i++){
UISelectItem selectItem = 

(UISelectItem)app.createComponent(UISelectItem.COMPONENT_TYPE);
SelectItem item = new SelectItem(i+"", "");
selectItem.setValue(item);
orderRadioButton.getChildren().add(selectItem);
}

And then you generate the panel where each radioButton element has the same
index as the radiobutton option in the past list and in the for attribute
they reference the HtmlSelectOneRadio component, the code is as follows (The
important lines are the last ones!!!):

component.getChildren().add(orderRadioButton);
for (int i = 0; i < dataFieldCollection.getCollCount();
i++){
altDataField fld =
(altDataField)dataFieldCollection.getCollObject(i);
HtmlOutputText fieldName = (HtmlOutputText)
app.createComponent(HtmlOutputText.COMPONENT_TYPE);
fieldName.setValue(fld.getField("DESCR"));
searchFieldsPanel.getChildren().add(fieldName);
HtmlInputText inputText = (HtmlInputText)
app.createComponent(HtmlInputText.COMPONENT_TYPE);
int entryLength =
Integer.parseInt(fld.getField("ENTRYLENGTH"));

inputText.setMaxlength(Integer.parseInt(fld.getField("ENTRYLENGTH")));
if (entryLength > 40) {
inputText.setSize(40);
} else {
inputText.setSize(entryLength);
}
searchFieldsPanel.getChildren().add(inputText);
HtmlSelectBooleanCheckbox returnCheckBox =
(HtmlSelectBooleanCheckbox)
app.createComponent(HtmlSelectBooleanCheckbox.COMPONENT_TYPE);
returnCheckBox.setSelected(true);
searchFieldsPanel.getChildren().add(returnCheckBox);
HtmlRadio radioButton = (HtmlRadio)
app.createComponent(HtmlRadio.COMPONENT_TYPE);
radioButton.setFor("fieldsForm:ordenar");
radioButton.setIndex(i);
searchFieldsPanel.getChildren().add(radioButton);
}

COOL!!!

HELP with h:selectOneRadio inside h:dataTable

[Jorge Vásquez]

Hi, I have no idea on how to include selectOneRadio
elements inside a datatable in order for each f:selectItem to be associated to
a different row, but all the elements belonging to the same radiobutton group.  I
am currently getting independent radiobutton elements for each row but I need
all of them to belong to the same group in order to allow only one of the rows
to be selected at once.

 

In case it helps I am currently using the code:

 

   

 

   

      f:verbatim>

 h:column>

 

   

      f:verbatim>

 h:column>

 

   

 h:column>

 

   

 

   h:selectOneRadio> 

 h:column>    

   h:dataTable>

 

Any ideas?

state handling for dynamic form elements in a table...

[Jorge Vásquez]

Hello, I am attempting to develop a page that has
some rows formed by input components, which are generated on the run according
to the contents of a collection as follows:

 

  






        #{dataField.description}   td>


        


   
  

  
     f:verbatim>

  
    td>

  





  
td>

  



input>
  


  
td>



   tr>

  
ui:repeat>

 

 

I have achieved the first part which is printing out
the list of rows successfully but I have no idea on how to keep the state of
the values that the user inputs as they aren´t specifically mapped to setters
of a managed bean since they are completely dynamic.  The managedBean
returns a Collection of elements of type dataField, which has getters for
description, userColumn, etc.  How can I guarantee that when the user
sends a submit the state that he entered is kept and mapped to the bean
somehow?

 

Another question that I have related to this problem
is the use of the selectOneRadio component?  I wasn´t able to use it to
generate dynamic radiobuttons since the syntax is something like:

 











 

And the options that I would have are each in a
different row and I have no idea where to place the container element: 
selectOneRadio?

 

Anyone has any ideas ?  

 

Regards,

JV

Problems with tree2 continue...

[Jorge Vásquez]

Hi,

I am working with Facelets and configuring the tree2
has resulted in a painful task.  

My current problem is to be able to maintain the
tree2 state after the page is reloaded (I am not using frames so each time some
item on the page is clicked I need to load the tree with the according state).  I
decided to change the clientSideToggle to false in order to experiment with server
state and haven´t been able to put it to work, I used this approach first:

id="menuTree" value="#{menu.treeModel}" var="node" varNodeToggler="t" org.apache.myfaces.tree2.CLIENT_SIDE_TOGGLE="#{menu.booleanFalse}"org.apache.myfaces.tree2.SHOW_ROOT_NODE="#{menu.booleanFalse}"org.apache.myfaces.tree2.SHOW_LINES="#{menu.booleanFalse}"org.apache.myfaces.tree2.SHOW_NAV="#{menu.booleanFalse}"> ...

 

And it didn´t work.

Then I decided to create a tag handler similar to the
one posted in:

http://wiki.apache.org/myfaces/Use_Facelets_with_Tomahawk

And to my surprise there´s no class named:

import org.apache.myfaces.renderkit.JSFAttr;

neither in tomahawk (version tomahawk-1.1.5-SNAPSHOT.jar)
nor myfaces (myfaces-impl-1.1.4-SNAPSHOT.jar) jars.  I did find two classes
named like that in other packages but none of them had the attributes:

 

JSFAttr.SHOW_NAVJSFAttr.SHOW_NAVJSFAttr.CLIENT_SIDE_TOGGLEJSFAttr.SHOW_ROOT_NODEJSFAttr.PRESERVE_TOGGLE

 

I really appreciate all the efforts done by everybody
with this tree2 component but just one question:  

¿Is this component ready for production-class
applications?

NOTE:  I have read all the documentation available
for the tree2 component but nevertheless I don´t seem to be able to grasp many
ideas behind it, Am I just the one with these problems?  I would kindly
appreciate some guidelines on how to thoroughly use this component…I
suggest the inclusion of more examples with different scenarios.

Navigation problems with FACELETS

[Jorge Vásquez]

Greetings to all,

Alter having many problems with JSP+JSF I decided to
give it a try with Facelets.  Everything started fine, my login page appeared
on screen and I was starting to get excited but unfortunately in our profession
excitement doesn´t lasts much and I am getting problems with navigation where I
get no message at all, no log, etc.  I followed the application in debug mode
and after clicking the submit button it went to the corresponding action method
in the managed bean and reached the end and returned the respective String
which in the faces-config is mapped to another page but nothing happens and the
same page is reloaded with no message at all.  Here I confess that I am
completely lost, how can I debug this?  Has anyone had a similar problem with
MyFaces+Facelets?  

Regards,

JV

RE: JSF + JSTL + Pure HTML--An Explosive Mixture

[Jorge Vásquez]

Thanks Andrew,
I think I know what is the cause of my html output being so strange, and it
is the include+subview, I have removed all Jsp and JSTL code and problems
persisted.  
I can´t imagine converting all pure HTML code to JSF, that would be hundreds
of hours of work!!!
Do you perhaps know of all the guidelines that I must follow for using the
subview functionality correctly? Or is there any alternative out there
beyond the jsp:include for including one jsp inside another?  (One that is
pure jsf...)

Jorge Vásquez

You cannot combine JSP and JSTL to my knowledge. If you want to use
JSTL with JSF, use facelelets and remove all JSP code (<%%>). I would
recommend not using JSTL (or JSP) code for JSF pages, they don't play
that well together. Facelets does support some of the JSTL
functionality, but the author (Jacob) recommends that you do not use
JSTL if at all possible.

The best thing for conditional rendering (if logic) is to use the
rendered attribute and when grouping components use the panelGroup
component. If looping, the Tomahawk dataList control is very useful.

Help in table conversion from HTML to JSF...

[Jorge Vásquez]

Greetings,

 

I am having tons of problems migrating a pure html
table to JSF, I don´t know if I am still not used to think in JSF terms but I
kind of get the impression that table components in JSF miss lots of features
that were present in html.

I enumerate some:

 

1.  How is it possible to associate an image to a td
as background in JSF:

Example in html:  

 

2.  How is it possible to define an empty td with
certain width:  

Example in html:  

 

3.  How is it possible to specify to a panelGrid
container that a bunch of elements must go under a td?

 

Does anyone knows of a table component in JSF that is
more closely related to the html table?

 

Thanks a lot,

JV

 

ManagedBean methods with arguments...

[Jorge Vásquez]

Hi,

I was wondering if JSF supports invoking methods in
ManagedBeans that have input arguments..

For instance, how can I convert the following pure
jsp code to jsf style (I am particularly interested in conversion for the
method:  getField(String arg)):

 

  <% String dlen = "0";

 for (int i = 0; i < flds.getCollCount(); i++){ 

     altDataField fld =
(altDataField)flds.getCollObject(i);  

     String fldVal =
(String)fldVals.get(fld.m_userColumn);

     if
(Integer.parseInt(fld.m_entryLength) > 40) dlen = "40"; else dlen = fld.m_entryLength; %>

   <TR>

 <TD align=right><%= fld.getField("DESCR") %>   TD>

 <TD><INPUT id="<%= fld.getField("USERCOLUMN") %>" name="<%= fld.getField("USERCOLUMN") %>" size=<%= dlen %> maxlength=<%= fld.getField("ENTRYLENGTH") %> value="<%= fldVal %>">input>   TD>

     <TD><input checked type="checkbox"
name="chk<%= fld.getField("USERCOLUMN") %>" value="1">input>TD> 

     <TD><input type="radio"
name="orderby" value="<%= fld.getField("USERCOLUMN") %>">input>TD>     

   TR>

 
<%
} %>

RE: Tomahawk tree2

[Jorge Vásquez]

Andrew, one last
request:  the TreeBean found in the source files (jsfCompAA-source.zip) is
incomplete:

 

/**

 * 

 */

package
warSource.net.sf.jsfcomp.aa.tree.examples;

 

/**

 * @author Andrew
Robinson (andrew)

 */

public class TreeBean

{

  public TreeBean()

  {}

}

 

Would you mind copying me
the full source for this Bean.

Thanks a lot and best regards,

JV
