Re: Tree2 and actionListeners

[Emmanuel Jay]

Not sure if this is a tree2 specific problem, I can just see that for
some reason the behaviour seems to have changed  in my app when I
switch to 20050822. Yes the actionListener is called in the
APPLY_REQUEST_VALUES(2) phase, and the repopulation is done before that
(which means that when I click on the commandLink) the data I retrieve
is wrong. The commandLink behave normally outside of the tree. The
dataTable is generated dynamically (in fact I generate n datatables
dynamically), and at the moment contains outputText and commandLinks.

I am really puzzled...On 8/25/05, [EMAIL PROTECTED] <

behave normally when it is outside of the tree?

Do you use input components to display
your data (in the dataTable)?

TR : Dynamic Locale change

Sorry 
for asking so much questions but I'll have to present my webapp very soon and I

Hi,
I'm trying to allow the 
application user to change the language of my web 
app.
I did it the way it is 
done in the myFaces 1.0.9 examples : a selectOneMenu with a choice of languages 
and an action button with that code :
 
OptionBean 
{
...
public String action 
{
    
...
    
FacesUtil.setLocale(selectedLocale);
    
...
}
...
}
 
FacesUtil 
{
...
public static void 
setLocale(Locale l) {
FacesContext.getCurrentInstance().getFacesContext().getViewRoot().setLocale(l);
}
 
...
}
 
 
It works fine when the 
action is executed (the language change), but as soon as I navigate to 
another page of the App, the language is resetted to the default one. Why 
?
 
 
NB : I'm trying not 
to use the locale parameter of the f:view tag

Re: RE : Let's write that doc!

[Martin Marinschek]

You know what?

There is nothing like "official" information. If you start off doing
the doc on the wiki, and it gets better than the one on the webpage
(and trust me, I will add a link to the corresponding wiki pages from
the component pages to ensure competitition is fair); your doc will
grow to be official.

Why don't we start an official doc competition? 

Ready - steady - go!

and after some time, we can reevaluate the approaches

Have fun documenting on the WIKI!

new panelTabbedPane problems

[Bogdan Sava]

I used until now myFaces 1.0.9 version.
Now I use tomahawk.jar lib nightly (20050824) .
Problems are :
1. panelTabbedPane from simple example does not work with h:commandLink 
instead of h:commandButton.
   If you are in second or third tab, after click h:commandLink, 
panelTabbedPane will displays first tab.
2. I cannot use dataTable inside of an tab (other than first tab) of 
panelTabbedPane, like I used in previews version (myfaces.jar 1.0.9).
   After click to change the page of dataTable , panelTabbedPane 
displays fist tab.


Is there a possibility to have server side switch of tabs of 
panelTabbedPane like  in previous version ? In tomahawk is  client side.

RE: Invalid bit mask of 14

[Vo, Ky]

I'm also getting the same error you had, "Invalid bit mask of 14".  I was
wondering how you solved your problem?  I'm using the latest build (8/24)
and am trying to use tree2 to create a dynamic tree.  I implemented my
actionListener like this:

public void addNewNode(ActionEvent event){
UIComponent component = event.getComponent();
UIComponent parent = component.getParent().getParent();

HtmlTree tree = (HtmlTree) parent;
TreeNode treeData = tree.getNode();
TreeNode newNode = new TreeNodeBase("name", "description", "identifier",
true);
treeData.getChildren().add(newNode);
}

--- in jsp ---

Subject: Re: Invalid bit mask of 14


Yes there is a way but its a bit difficult to pull off without something
like Shale's prerender method.  There is a expandAll method on the
UITreeData but there's a catch.  It can't be called until the tree has been
populated with all of the model stuff.

I can really see a way to have it as a *property* on tree2 (ie. )  This is coming from the new
TreeState interface which maintains the expanded state of the nodes.  You
can't set all of the nodes to be expanded until you have all of the nodes
loaded into your TreeModel.

Of course you could come up with your own TreeModel/TreeState combination
that will do this but its difficult to provide one that is appropriate for
all sorts of scenarios (dynamic model and well-defined tree model where all
nodes are known in advance.)

I'm still trying to figure out a way around this problem.  Let me know if
you come up with any ideas.

I'm standing on the sidelines on this particular issue, but it is
worth making a point here ... people who end up making major
contributions to the open source community tend not to pay any
attention to "we've always done it this way" sorts of limitations, and
go do their own thing.  In the context of the current discussion, you
are making a *horrendously* incorrect assumption.  Why do you *care*
if the existing MyFaces developers think a wiki is the right way to
accumulate sufficient useful documentation in the short term?

Just do it.

If your idea works ... that is, we see MyFaces users gather together
and actually create significant quantities of documentation of
significant quality, the very concept will catch on like wildfire. 
>From what I know of the PHP community, this certainly seems to be
possible.  On the other hand, if nobody contributes, you will have
turned out to be one of the many idealists who have a great idea for
what someone *else* should do, but nobody else buys in to doing the
actual grung work.

The assumption that whatever user-developed wiki based documentation
*must* be blessed by the MyFaces developers as "official" is
ridiculous -- *please* go create the documentation that you, and other
MyFaces users, need!   I can vouch for the fact that the MyFaces
developers are "smarter than the average bear" (yes, dating myself to
Yogi Bear cartoons :-).  If what you create causes a groundswell of
participation, the MyFaces developers would be foolish to ignore it.

On the other hand, maybe nobody else other than you actually cares
enough to contrbute to this effort.  Then, it's perfectly legitimate
for the MyFaces developers to switch over to a totally different (yes,
still US-centric :-) TV commercial paradigm, and ask "where's the
beef?"

For the last year or so, I've taken on the personal mantra (related to
open source involvement) that "code speaks louder than words".  In the
global context of making open source a globally used technology,
documentation is at *least* as important as code.

So, where's the beef?

[ANNOUNCE] A Call for Volunteers

The MyFaces team has created a new Wiki that we plan to use to keep
users informed of our current needs.  If anyone would like to do a
little extra to help the community effort you can check out the wiki
for details on where we need assistance:

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

The MyFaces project is growing very rapidly right now.  We have lots
of new users, bugs, enhancements, etc.  The MyFaces JSF implementation
is also about to undergo preliminary JSF 1.1 compatability testing. 
Following the results of these tests we will have even more to do as
we address newly uncovered issues.

Any assistance will be appreciated.  Thanks to all of the contributors
so far who are now becoming too numerous to mention.

Navigation bug through browser previous button

[Clément Maignien]

Title: Message



Hi 
everybody,
there's a bug in my 
webapp when I use the browser "previous page" navigation button instead of 
my custom links :
When clicking 
"previous page" the button, the previous page displays well but redisplays as 
soon a I do an action in the page and as a consequence skip 
it.
 
In my opinion, this 
could comes from the SERVER_STATE saving method associated to the redirect 
instruction in my faces-config.xml.
Does it comes from 
that ? if yes, is there a solution to this problem without switching to the 
CLIENT_STATE saving method ? if no, where does it comes from 
?
 
Thanks for your 
help
Clément.

Re: Having trouble with JSTL inside JSF

[Udo Schnurpfeil]

* The fact that you can use a value binding expression on nearly
  every attribute makes using rt expressions redundant ... you can
  do anything you need with a value binding anyway.


A very powerful feature in JSP 2.0 are "Custom Tags".

Having a bean Foo in your application with several instances.
Now you write some code to edit this bean. If you put this code
into a custom tag like

WEB-INF/tags/beans/foo.tag begin --

<%@ attribute name="bean" %>




foo.tag end 

you can use this snip many times on your jsp like

page.jsp begin --

Is there a way in JSF 1.2 / JSP 2.1 to make such sniplets run without

In JSF 1.2 / JSP 2.1, the concepts are getting unified ... but in the
mean time (when the JSP container doesn't know what a value binding
expression is) this was the decision made at the JSF spec level.

tree2 help needed urgently.

[Kolhe, Pallavi \(Cognizant\)]

Hi ,

 

I’m using tree2 component in my project.

 

In my listener class  I  retrieve  the  currentnode
clicked  whose value I have to  pass to  my treeBacker  class
for some processing.

 

Is there any way of maintaining state given in myfaces API
.. ??

 

Please let me know ASAP .

 

Regards.

Pallavi.

MyFaces Ajax by Smirnov

[Enrique Medina]

Hi,

I suppose some of you are using the great AJAX framework provided by Smirnov.

I was trying to simple give AJAX power only to the datatables in my application, so:

a) I added the new CommandLink renderer to the faces-config.xml file
b) I added the tag  to the page where my datable is
defined using  (actually my page is a subview - I'm
using Tiles)
c) I added the necessary JARs to my LIB folder

When I run the application, the page gets perfectly rendered, but when
I click on the scroller, nothing happens. I go to the _javascript_
console and this error is shown:

Error: [Exception... "Component returned failure code: 0x80040111
(NS_ERROR_NOT_AVAILABLE) [nsIXMLHttpRequest.getResponseHeader]" 
nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)"  location: "JS
frame ::
http://localhost:8080/DeltaR/faces/myFacesExtensionResource/ajax.UIAjaxViewComponent/11245933/JSFAJAX.js

:: anonymous :: line 48"  data: no]
Source File: http://localhost:8080/DeltaR/faces/myFacesExtensionResource/ajax.UIAjaxViewComponent/11245933/JSFAJAX.js

Line: 48

where the source line is:

  	  var idsFromResponse = req.getResponseHeader("Ajax-Update-Ids");

So my questions are:

a) Is it possible to only use this AJAX framework to have AJAXed datatables (just changing the CommanLinkRenderer)?
b) What is the difference between  and
? Which one should be used when inside a
, as I am using tiles?

Thanks for your help ;-)

Re: Having trouble with JSTL inside JSF

[Udo Schnurpfeil]

Hmmm, I worry about this will not solve my problem.

I understand the t:aliasBean to use like this:

page.jsp begin --







page.jsp end --

and use   in the custom tag.

So far, so good.
But, I want to use, of course, the tobago layout manager for layouting:


   

   
   

   
   


The layout manager has to know all of its containers children to make an 
appropriate layout. So the panel has rendersChilden=true, and all the 
tags will be parsed before rendering.


In the moment where #{foo.firstname} will be evaluated by the renderer 
(2 times), the value of #{foo} equals #{foo2}, because it will be done 
at the end tag of the panel ().

Udo

A very powerful feature in JSP 2.0 are "Custom Tags".

Having a bean Foo in your application with several instances.
Now you write some code to edit this bean. If you put this code
into a custom tag like

WEB-INF/tags/beans/foo.tag begin --

<%@ attribute name="bean" %>




foo.tag end 

you can use this snip many times on your jsp like

Re: TR : Dynamic Locale change

[Udo Schnurpfeil]

If you set the locale in the UIViewRoot manually, I don't know if it 
will be passed on to the next UIViewRoot.


One solution for you might be putting the users locale in the session 
(e.g. the key "locale" or "user.locale" if your have a user object) and 
use the locale attribute  or locale="#{user.locale}"> on all of your JSF pages.

Hi,
I'm trying to allow the application user to change the language of my 
web app.
I did it the way it is done in the myFaces 1.0.9 examples : a 
selectOneMenu with a choice of languages and an action button with that 
code :
 
OptionBean {

...
public String action {
...
FacesUtil.setLocale(selectedLocale);

}
...
}
 
FacesUtil {

...
public static void setLocale(Locale l) {

FacesContext.getCurrentInstance().getFacesContext().getViewRoot().setLocale(l);
}
 
...

}
 
 
It works fine when the action is executed (the language change), but as 
soon as I navigate to another page of the App, the language is resetted 
to the default one. Why ?
 
 
NB : I'm trying not to use the /locale/ parameter of the /f:view/ tag ...
 
Thx,

Re: Invalid bit mask of 14

[Sean Schofield]

Sigh,

This question keeps coming up.  The error message is definitely
cryptic and I will address that shortly.

We changed the bitmask code that renders the navigation controls at
the request of a user
(http://issues.apache.org/jira/browse/MYFACES-350) who made a strong
case for this.  The old way of deciding on whether or not to render a
'+/-' icon was to check in part if the node had children.  This caused
problems for some dynamic trees (again see JIRA issue).

According to your code each new node that is added is being considered
a leaf (b/c of the 'true' in your TreeNodeBase constructor.)  Yet the
node is coming back as expanded (I know this b/c of the bit mask total
- see source or my earlier message for the values.)  A leaft cannot be
expanded, it is a leaf.

Re: Tree2 and actionListeners

[Sean Schofield]

I would agree with Mathias that this doesn't seem to be a Tree2
problem, especially if your actionListener is getting called.

What do you mean by the "repopulation is done before that"?  The
component tree will be recreated and the tree data can be set but it
should still be possible to add to the tree data before rendering.

Re: tree2 help needed urgently.

[Sean Schofield]

You want to know which node was clicked or do you want to preserve
that information?  To find out which node was clicked, you can add an
actionListener and check the node identifier.  It won't give you the
true node id that the model uses but the identifier will be whatever
you set it to so you can choose something meaningful.  The most
recently selected node is also known to tree2 but there seems to be a
minor issue with that at the moment.

Re: Having trouble with JSTL inside JSF

in fact, you would use the alias bean like this:


   

   
 


   
   



but in any case, you are right, the JSF expression is not there any
more when you close the t:panel tag.

RE : TR : Dynamic Locale change

[Clément Maignien]

Thx Udo but look at the NB of my first message ---> NB : I'm trying not to use 
the locale parameter of the f:view tag
This solution works (I've tried it) but not so clean in my opinion.

The use of 
FacesContext.getCurrentInstance().getFacesContext().getViewRoot().setLocale(l) 
should work as it work in the myfaces1.0.9 examples.

Anybody ? Other ideas ?

Thx again Udo

I suggest you take a look at the list archives for "Maintain locale

I had a similar issue and it seems the locale is not maintained

In the end I set , where visit is a

rowOn... scripts not fired when creating datatable programmatically

[Emmanuel Jay]

Hi,

Have any of you seen any issue with setting the rowOnMouseOver,
rowOnMouseOut... fields of a datatable programmatically. I am
dynamically generating datatables, and the scripts do not seem to be
triggered (they were triggered correctly when I was declaring and
creating the datatable in the jsp). In my code I have:

dataTable.setRowOnMouseOver("this.style.backgroundColor='#B5'");

Re: TR : Dynamic Locale change

[Martin Marinschek]

The solution would be quite similar to what was done in a
collaborative effort on the mailing list - install a phaselistener,
store it in the session, restore it from the session after the
redirect.

RE : TR : Dynamic Locale change

[Clément Maignien]

OK thx Gianni.
So if I sum up things :

2 solutions to dynamically change your application locale :

*1- If you use the server STATE_SAVING_METHOD with somes  
instructions :
Create a bean to save the locale choice
This bean must be in session scope or request + saveState
Then in each page of your application that needs to be localized, add the 
locale parameter to them : 

*2- If you use the client STATE_SAVING_METHOD ( -> no  instructions) 
:
Use the UIViewRoot.setLocale(Locale l) method.
For example : 
FacesContext.getCurrentInstance().getFacesContext().getViewRoot.().setLocale(l);

Clément

I had a similar issue and it seems the locale is not maintained

In the end I set , where visit is a

Re: Method binding calls not being made

[Mike Kienenberger]

Possibly validation is failing and the lifecycle never reaches the
point where it would execute your action.

You might try sticking in 




and see if anything shows up.

Otherwise set a breakpoint in LifecycleImpl.execute() and see what
phases are being executed.

Re: validation skipped w/ commandLink and inputText

[Mike Kienenberger]

Are the table/column/inputTexts set to be rendered?  Phases are
skipped for non-rendered components.

Otherwise, it sounds like a bug.

The solution would be quite similar to what was done in a collaborative effort

Using

[CONNER, BRENDAN \(SBCSI\)]

I recently tried to use an  tag against a 
tag and received a compiler error saying the id specified by the
for="..." attribute was not found.  When I changed  to
, the compiler error went away.  If, instead, I changed
 to , the error also went away.

So the bottom line, I guess, is that, when using a Tomahawk component,
any outputLabel tag used to refer to it also has to be from the Tomahawk
library.  (By contrast, a Tomahawk outputLabel can be used against a
Tomahawk or non-Tomahawk tag.)

Can someone explain why there is this restriction?  It's easy enough to
use  everywhere, but I was just curious.

Opening a new window

[Emmanuel Jay]

Hi, 

I would like to know if there are any solution to open a new (sub)
window with MyFaces.  I have a button on my main page and on user
clicc I would like to open a new window and display some data in it.
Are there any other solutions than using _javascript_? Can the JSF
navigation system handle that, and if yes how is it do-able?

Thanks for your help,

Emmanuel

Fwd: Experience with developing web app. based on MyFaces

[mirek novak]

Hi,
 I've been working on an application based on MyFaces 1.0.8. Now, we
are moving to MyFaces 1.0.9 and I would like to discuss discovered
issues and some ideas (not only related to MyFaces but to JSF in
general).


 AliasBean

   * This is a pretty useful component and I'm glad that MyFaces contains it!
   * There were a few bugs in this component in MyFaces 1.0.8
(processSaveState, queueEvent) but now they are fixed (1.0.9) - great

Table

   * This is one of the most used components
   * It's definitely better than standard table (sorting support,
scroller, …) BUT:
  * Suppose this (selecting a row while model has been
concurrently modified by a different user):

 1) Your table has 3 rows and you display a check box for each
row so that user can select a row

 2) User selects first row and submits but another user has
concurrently deleted first row. So, model has now only 2 rows.

 3) Submitted value (selected checkbox of the first row) will
be applied to the first row of the model. So, actually the second row
is selected :-(. (we've developed a quite simple solution, so if you
are interested, let me know - and we definitely do not serialize whole
model of the table!)

  * It's a common case that table rows have checkboxes and can be
selected. So, we have to provide (for most of the tables) model where
each row is wrapped in an extra class that has "selected" property -
and that's tedious.

DataScroller
=
   * We've discovered following issue: uiData.setFirst(someNewValue)
is used within the =decode= method of the HtmlDataScrollerRenderer -
it is too early to modify uiData within =apply request values phase=.
  * If some rows of the table were modified too, they will be
applied to wrong table rows :-( (because setFirst has already been
called and table contains different rows now)
   * Our solution: DataScrollerRenderer fires an even that uiData
should be updated, and they are updated later in =update model values=
phase (just after model has been updated)

Backing Bean's State, HttpSession, Concurrent Access within a Session
===
In my view, a reasonable web application should fulfill following requirements:
   * users can use browser's navigation buttons (back, forward, reload)
   * users can use an application from multiple browser tabs (tabs
share the same session)

Although these requirements look simple and unimportant, they present
serious problems and have serious consequences on the whole
architecture of an application.

   * navigation buttons
  * We use redirects. So, user can use the back button even when
he's moved to a next page via HTTP POST
  * We use javax.faces.STATE_SAVING_METHOD=client. So, even if
user has pressed the back button 10 times, a proper view will be
restored when he submits form (or clicks link) on the old page (if
state saving=server, this would obviously not work - you would have to
"click twice" to perform an action :-)).
  * But who/when/how will store state of backing beans? - note
that if you not store the state of your backing beans on a client,
your application will not work. Suppose this:

 1) Your page displays a category (it has name, description
and sub-categories)

 2) User selected category A and it is stored in a property
=currentCategory= in your backing bean

 3) User selected category B (sub-category of A), so
=currentCategory= is now B

 4) User uses browser's back button, so he can see detail of category A

 5) User edits description of the category (A) and submits the page

 6) Description of category B will be updated because
=currentCategory= is still B :-(

   * Solution: a component (saveState) that accepts a value binding
and saves the "value" within its state. E.g. 

   * tabbed browsing
  * Any session scope backing bean is a potential race-condition
  * Moreover, if your data like "currentItem", "MyPageConroller"
have session scope, actions performed in one tab may influence
behavior of the other tab


Error Handling
===
   * We created a special component similar to the Buffer component.
We render a sub-tree of this component into the buffer and if and
exception is thrown while processing the sub-tree, we render the
exception. (in addition, we had to wrap ActionListener,
HtmlDataTablePhaseListener, …).

   * It would be nice to see an errorHandling component in next
MyFaces distribution.

I hope that you will find some info from this mail useful and intelligible.

Best regards,

MN.

I think that you are not right:
  - problem is that sequence number of the rows has changed (this
problem arises whenever sequence number (position) of a row changes
before the page with table is submitted)
 - we are displaying life data, so if user's had a break and after a
while submits the page with the table and data (in db) has been
modified concurrently, submitted values will be applied to bad rows
:-(
 - if model were cached in the session, it would surprisingly work -
because if the model is cached, it cannot be modified concurrently by
a different user

we've extended MyFaces table. Our table expects "stronger" data model,
that extends DataModel but implementation of our model must: return id
of any row, return value of a row by ID

So, when the method saveState is called on our table, we store IDs of
displayed rows (from first to first+rows). So, if table is scrolled
(10 of 1000 rows is displayed), we will serialize only IDs of
displayed (10) rows.

When table is to be restored, we read serialized row IDs, ask for data
(getRowDataById(id)) and we provide a temporary model - this model
contains exactly the same data as when the page was previously
rendered. After all the request values were applied and model is
updated we just restore original model (maybe model contains more or
less rows, maybe in a different order ...)

Btw. I will definitely check your project :-)

Re: x:convertBoolean

[Sean Schofield]

Docs are required and unit tests are a definite plus.  If you thought
we were bad with documentation, the lack of unit tests is even worse! 
We're slowly getting on top of that though.  As we add more committers
and get through JSF 1.1 certification we will turn our attention to
testing.  If you can add simple unit tests that don't require cactus,
etc. then please add those as well.

Re: Experience with developing web app. based on MyFaces

[Sean Schofield]

Better take a look at the latest nightly build.  I suspect several of
your issues have been resolved already in the upcoming 1.0.10 release.
 We're probably 2-3 weeks away from the release and now is the time to
let us know about bugs.  (Feature requests can wait until future
relelases but bugs should be addressed *now*.)

RE: [jira] Commented: (MYFACES-447) tree2 TreeNode interface has too many methods

[CONNER, BRENDAN \(SBCSI\)]

Title: Message



There 
actually are subtle differences among isLeaf(), getChildren.size(), and 
getChildCount() that are useful:
 
1. 
When doing "on-demand" population of the tree, isLeaf() can be false even though 
there are no children loaded yet (i.e., getChildCount() == 
0).
2. I 
believe that getChildCount() is available for performance reasons 
in situations where actually getting the children just to determine 
the list size can be expensive.

  not used by any tree2 code. And TreeNodeBase keeps behaving as it did before

  takes cleaning up the interface further. But since the differences between 
  isLeaf(), getChildren().isEmpty() and getChildCount() == 0 on the one hand, 
  and getChildren().size() and getChildCount() on the other hand, are rather 
  obscure (and, as far as I can see, not applied consistently in the existing 
  tree2 code either), I bet that there are not that many users out there that 
  depend on the differences. If so, please let me know here: it might increase

Tree2 - problem with the states of the nodes

[Patel, Hitesh \(Exchange\)]

I am using the tree2 in Myfaces and my requirement is to get
the data from the database and build the tree nodes every time a node is
expanded. If an expanded node is collapsed I want to remove the nodes under
this node from the tree and add the nodes afresh by getting the data from the
database when that node is expanded again.

 

I am facing the problem that even if I remove the child
nodes of the node that I collapse, when I add the nodes again when I expand
that node it seems to remember the state of the child nodes before I collapsed
the parent node and removed these child nodes. So if I had a child node which
was expanded before I removed it, the next time I expand the parent node and
add these child nodes and I click on this child node that was expanded it will
not expand on the first click as it was expanded when I removed this node. On
the second click It expands. I believe it is collapsing the state on the first
click and on the second click it is then expanding. How do I remove the state
of the child nodes that I remove from the tree.

 

I use…..

 

List children = node.getChildren();

Children.removeAll(children);

 

…. to remove the nodes. Is there another better way to
remove the nodes or am I doing it correctly. IF this is correct then how do I
remove the states of the nodes the tree maintains.

 

Any help is much appreciated.

would retrieve the employee based on the id of the employee in the list.

I'm used to doing this with a simple link  John Doe Edit
With JSF I'm not so sure about how to do this. My JSF
book mentions briefly about passing in f:param in commandLink but
doesn't show how to retrieve this param.

As a side note I find this very interesting, I was testing by using a
DataTable and providing a commandLink next to each employee for each
row...


  emp.id}"/>
 

One of the odd/interesting things is that when I cycle through and
print out the Request parameters I noticed that I'm getting a single
parameter (assuming a map) that actually has the Employee info that I'm
concerned with (2nd one):

8/26/05 02:28:55 PM  DEBUG net.reumann.Employee editAction - param = [EMAIL PROTECTED]
08/26/05 02:28:55 PM  DEBUG net.reumann.Employee editAction - param = id: 3, name: Rachel, age: 26
08/26/05 02:28:55 PM  DEBUG net.reumann.Employee editAction - param = /employees.jsp

That second enry *does* correspond to the button I clicked but not sure
how I'm supposed to get a handle to the id (actually I'm not even sure
how the heck that got into the request based on the commandLink I set
up)?

Also the f:param "empID" is *not* seen as a request parameter when I loop over them.

What is the typical procedure for providing a link or button to click
on that isn't part of a form but should fire off an action method that
will look up something based on parameter(s) ?

[Patel, Hitesh \(Exchange\)]

You can pass the parameter as you have
done and get the value of the parameter as follows

 

FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("empID");

Hi Sean, 

  

I am using the tree2 in Myfaces and my requirement is to get the data
from the database and build the tree nodes every time a node is
expanded. If an expanded node is collapsed I want to remove the nodes
under this node from the tree and add the nodes afresh by getting the
data from the database when that node is expanded again.

  

I am facing the problem that even if I remove the child nodes of the
node that I collapse, when I add the nodes again when I expand that
node it seems to remember the state of the child nodes before I
collapsed the parent node and removed these child nodes. So if I had a
child node which was expanded before I removed it, the next time I
expand the parent node and add these child nodes and I click on this
child node that was expanded it will not expand on the first click as
it was expanded when I removed this node. On the second click It
expands. I believe it is collapsing the state on the first click and
on the second click it is then expanding. How do I remove the state of
the child nodes that I remove from the tree.

  

I use….. 

  

List children = node.getChildren(); 

Children.removeAll(children); 

  

…. to remove the nodes. Is there another better way to remove the
nodes or am I doing it correctly. IF this is correct then how do I
remove the states of the nodes the tree maintains.

  

Your help is much appreciated. 

  

Thank you, 

Hitesh

[Mike Kienenberger]

You can also use dataTable.getRowData(), provided your model data is
consistent, and then you don't need to create or pass a parameter.

public void editRecord(ActionEvent event)
{
dataStore.editRecord(dataTable.getRowData());
}

Re: Dealing with links/buttons to fire off an action? confusion on how to set this up

[Dennis Byrne]

Do you know of any way to do this if the underlying DataModel 
is in a property of a request scoped bean and the you 
couldn't use preserveDataModel="true", t:saveState, or any 
other things beyond the spec itself ?  I am in such a 
situation and the only solution I see at this time is using 
f:param in the JSP and server side manual request parsing.

Re: Dealing with links/buttons to fire off an action? confusion on how to set this up

[Mike Kienenberger]

Nothing comes to mind, but allowing the end-user to specify the target
record by key (generally a database primary key) may cause security
issues.   You'll have to validate the suitability of key provided when
used.

Re: Dealing with links/buttons to fire off an action? confusion on how to set this up

[Dennis Byrne]

I found a way to address the security issues when the 
navigation path is to and from the same JSP .  I use a 
converter where getAsString encrypts and encodes the id on 
the way out, getAsObject decodes and decrypts the string 
coming in.  This however can't be used when navigating from 
one view to the next.

If anyone has ideas on the first problem, do not be shy.

MyFacesGenericPortlet

[Patrick Dalla Bernardina]

When I execute nonFacesRequest to go to a view without obeying 
navigation-rules the state of Navigation is not saved.


So, after that, when I click the maximize or restore button of portlet 
the portlet goes back to the previous page.


How can I change this navigation state?

 I
would guess this common to have to use? I would think it would be, and
find it a bit odd that there isn't a more convenient way to get the
params. Granted I can probably make a helper method to do the above. 

I know that in many of my apps I have cases where you'll click on a
link or button in order to get to a different populated screen based on
an id or some other var(s). For example in one app there are a lot of
page that on the top of the page it displays the user you are looking
at and provides a few convenience buttons next to the name for viewing
'summary' 'user logs' etc - which are just links that execute actions
and the appropriate information is pulled back based on some params
passed through the link. -- Rick

Can you explain this a bit more? For example will it matter if another
user ends up going to the same JSP and has a 'different' view of the
dataTable while I'm working with it in the editRecord method above? I
would think that it wouldnt' matter but just double checking.

Title: Message



There's a good example of getting row-specific events in the 
O'Reilly book JavaServer Faces (Hans Bergsten), pp. 173 - 178.  The example 
application throughout the book is to build an expense report application, and 
it makes use of the summary-detail links you refer to.

Not as long as the data model is contained in your component tree or
session rather than in some global location.

Re: Dealing with links/buttons to fire off an action? confusion on how to set this up

[Gary VanMatre]

I'm a fan of the Struts ActionForm.  If you wanted to populate an object with 
query parameters, you might think about creating a managed bean and use the 
setter injection stuff.  



   formBean

   xxx.FormBean
   request
   
  username

  #{param.username}
   


You could use a helper method to get to the "formBean".  Struts Shale 
ViewController would be a perfect fit for this pattern.  It has a helper method 
called getBean();

public void prerender() {
FormBean queryParams = (FormBean) getBean("formBean");
String userName = queryParams.getUserName();

}

 I
would guess this common to have to use? I would think it would be, and
find it a bit odd that there isn't a more convenient way to get the
params. Granted I can probably make a helper method to do the above. 

I know that in many of my apps I have cases where you'll click on a
link or button in order to get to a different populated screen based on
an id or some other var(s). For example in one app there are a lot of
page that on the top of the page it displays the user you are looking
at and provides a few convenience buttons next to the name for viewing
'summary' 'user logs' etc - which are just links that execute actions
and the appropriate information is pulled back based on some params
passed through the link. -- Rick

- preserveDataModel serialized whole model - this is an overkill
- we tried this, but the page broke down (maybe we used some wrong
technique, but with preserverDataModel=true functionality of the page
was corrupted)

I'll take a look at it.

Yes, some issues have been already resolved - a few minutes after
sending this mail I've come across saveState component that works
*exactly* the same way as our component :-)

RE: Dealing with links/buttons to fire off an action? confusion on how to set this up

[CONNER, BRENDAN \(SBCSI\)]

Title: Message



 is trivially simple to use, but it's a Godsend.  
Wherever you want the state of a bean to be maintained across requests, just 
declare the bean with request scope and put a  
declared for it, at which point it will go away 
automatically.
 
So 
wherever you need to maintain the state of a bean for more than one request (but 
don't need it for the entire session), stick in a  tag for 
all pages that use it, and you're set.
 
If you 
do this, and you follow Mike Kienenberger's suggestion to access the DataModel 
object that backs the dataTable component (illustrated in the O'Reilly book 
JavaServer Faces, pp. 175 - 179), you're all set; you don't need to 
pass any parameters through the request.
 
Using 
the DataModel object also is explained in the book CoreJavaServer Faces 
(Geary, Horstmann), pp. 185 - 201.
