One last note, I said to custom render the UICommand, but that is not
needed, just set ting the onclick attribute is probably all that is
needed

Another thought:

I kept looking at the API for A4J, and found a server side API that
will work for including the zones to refresh:

AjaxRendererUtils.addRegionsFromComponent(javax.faces.component.UIComponent
component, javax.faces.context.FacesContext context)

No the only thing you would need to do is cause A4J to post back via
AJAX when the UICommand object is clicked instead of using a stanard
post.

This looks doable via the method:
AjaxRendererUtils.buildOnClick(javax.faces.component.UIComponent
uiComponent, javax.faces.context.FacesContext facesContext)

So this new approach would be:

1) extend UITreeData
2) override getExpandControl() and return a custom UICommand that
renders itself. In that rendering, call the "buildOnClick" method
above to cause A4J to handle the post.
3) create an attribute on the extend UITreeData class called "reRender".
4) override toggleExpanded() and in that method, after calling the
super method, call "addRegionsFromComponent", passing "this" (without
the quotes of course) as the component.

Since I don't have A4J running, I can't test this, but I don't see why
it wouldn't work.

I've seen these used for styleClasses but haven't found their source:  "

sorting with t:saveState and t:dataTable

All,
I have been unable to get sorting to work when using t:saveState

ListDataModel that I am sorting on) via t:saveState.  I have looked
through the wikis and it looks like there is nothing to it.  Are there

RE: ajax4jsf + tree2?

2006-09-22 Thread Hagen, Nicholas

That is actually what I ended up doing (at least to a certain degree...see
below) to produce a working AJAX tree2 implementation.  However, I second
(from your next post) that the tree2 UITreeData component should be changed
to return UIComponent instead to allow any expandable component.  If the
tree really required an actionable component, it could test for whether the
returned component implements ActionSource and fail accordingly if it does
not.  However, I would just put the requirement on the user to ensure they
use an actionable component if they want to the tree to work properly.

My actual component ended up being something like:

class AjaxLink extends UICommand
{
public AjaxLink() {
// Does not require a renderer (delegates to Ajax renderer)
this.setRendererType(null);
}

public void encodeBegin(FacesContext)
{
// Create Command Link and copy children from here to there
UIComponent cmdLink = new HtmlAjaxCommandLink();
while (this.getChildren().size() > 0)

cmdLink.getChildren().add(this.getChildren().get(0));

// Add command link as a child of us so we render the cmd
link
this.getChildren().clear();
this.getChildren().add(commandLink);
super.encodeBegin(context);
}
}

Re: ajax4jsf + tree2?

BTW - instead of decorating UICommand, you could request a change of
the API of UITreeData:

Change HtmlTreeRenderer.java (1.1.3) line 577 from:
UICommand expandControl = tree.getExpandControl();
to:
UIComponent expandControl = tree.getExpandControl();

Change line 111 of UITreeData.java (1.1.3) from
public UICommand getExpandControl()
to:
public UIComponent getExpandControl()

The renderer doesn't do anything special for this component that would
require it to be a UIComamnd, the author just assumed that the
standard JSF component would be used to expand/collapse. If the author
accepts this patch, then you wouldn't have to decorate the UICommand
component.

Re: ajax4jsf + tree2?

That solution may not work. I just downloaded the last A4J release and
UIAjaxCommandLink is not a UICommand:

java.lang.Object
 extended by javax.faces.component.UIComponent
 extended by javax.faces.component.UIComponentBase
 extended by org.ajax4jsf.framework.ajax.AjaxActionComponent
 extended by org.ajax4jsf.ajax.UIAjaxCommandLink

That means that it would not be compatible with that API. However,
with a little messy use of the decorator pattern, you could create a
UICommand component that delegates all methods to an internal
UIAjaxCommandLink class instance. This way the link that would be
rendered to the HTML would be the AJAX one instead of the standard
one. It wouldn't be the prettiest code, but it should function quite
well. Since the command link would be the A4J one, you wouldn't have
to do any more work. So the process would be:

1) extend UITreeData
2) override getExpandControl()
3) Create a decorator of UICommand that houses UIAjaxCommandLink
4) delegate all methods of the UICommand to the UIAjaxCommandLink for
those methods that are requried (you may not have to decorate them
all).
5) Register your new UITreeData in the faces config, and register the
component in taglib.xml for facelets or create a TLD and tag file for
JSP

This should work assuming the decoration of UICommand to wrap a
UIAjaxCommandLink doesn't present any unforseen issues.

Re: ajax4jsf + tree2?

The way that AjaxAnywhere works is that it builds a Set of
"zones" during the processing of a request. JavaScript can start that
Set and then there is an API on the server
(AAUtils.addZonesToRefresh(ServletRequest, String) method) that one
can use.

So in my approach, I let aa.js submit normally (no zones on the
client), then I extend UITreeData & overload the toggleExpanded
function. In that function, I check the "ajaxZone" attribute of my
extended tree component and use that addZonesToRefresh method to make
my tree re-rendered

If you look in the HtmlTreeRenderer class, you will see the following
in the server-side rendering:

UICommand expandControl = tree.getExpandControl();

This means, that if in your extended UITreeData class, you override
the "getExpandControl()" method, you can return an A4J command link
instead of the "standard" one. In there you also have access to the ID
of the tree (since your code is the tree component), so setting the
re-render attribute should be very easy.

This way you can still use the built in navigation icons of the tree.
If I get a chance, maybe I can play around with it sometime and create
a new jsf-comp like the one I did for AA but for A4J. If this email is
enough, please feel free to write a blog or the component yourself.

Re: Dynamically generated command links

2006-09-22 Thread K. Johnson

Did you make sure the command links have unique component ids? 
Its hard to help your problem without a code snippet, but We generate 
commandLinks in our application that use actionListeners without any problems.

Re: Re-render JSF page components

2006-09-22 Thread K. Johnson



My navigation bean is session scoped already? 
I'd like to somehow force the page to rebuild when it is refreshed? Can this be 
done? 
Can the viewRoot be forced to be completely re-created, so that the components 
will 'hide' on page refresh, if they have previously been displayed, and 
vice-versa? 

It seems like once the component is rendered it stays cached when I refresh the 
page

Re: how to access a managed bean from a button action listener ?

2006-09-22 Thread K. Johnson


You can also use: 
FacesContext facesContext = FacesContext.getCurrentInstance();
MyBean myBean = (MyBean) 
FacesContext.getApplication().createValueBinding("{MyBeanAliasUsedInFacesConfig}");

This accesses the managedBean in context.

Okay, so the trick is to use showNav="false" and make your own
navigation togglers with an a4j:commandLink. It works, but it is
difficult to make the new links look just like the originals. I gave it
a shot (see below), but it still looks pretty ugly.

Perhaps a better solution would be a new tree2 attribute called
'a4jToggle', which when set to true puts in the magic a4j javascript
(not sure exactly what that looks like) instead of the standard js.

Re: ajax4jsf + tree2?

That is not true. Lazy loading means that child nodes are created when
the parent is expanded and not until then. If you create the whole
tree model all at once, you are fully loaded, regardless of when the
nodes are rendered. Lazy loading refers to model creating, not
rendering time.

As for AJAX, in AjaxAnywhere, just put a zone around the tree and when
the nodes are expanded/collapsed, just add the zone to the list to
refresh. As for Ajax4jsf, I think (I haven't had a chance to use it
yet) just wrap a panel around the tree, then add that panel to the
re-render list when a node is expanded or collapsed.

I'm looking for AJAX expand-collapse when the +/- icon is clicked. It
would be okay if the entire tree was refreshed, just not the entire page!

One other thing though.. I see lots of references to AJAX lazy loading.
What is that supposed to mean? AFAICT tree2 supports lazy loading out of
the box, and it has nothing to do with AJAX. Just set
clientSideToggle="false".

Tomahawk 1.1.3 inputFileUpload solution

2006-09-22 Thread JBuilderDoug


I finally figured this out, so  I'm going to put an entire example in this
post.  I'm using Tomahawk 1.1.3 with RI JSF created in Borland's JBuilder. 
I've created a .war file from borland and deployed it under Tomcat 5.5 so it
should be Borland independent.  The problems I was having previously were in
trying to deploy Tomahawk on a old JSF project. I'm pretty sure I'm safe in
saying you must use JSP 2.0 and Servlet 2.4 as a minimum.

inputFileUpload/Tomahawk specific elements are bold/italic

In the backing bean WelcomeBean.java, I only read the uploaded file into a
byte [].  In my personal application, I simply insert the byte [] into an
Oracle BLOB.  You may need to write it to a file.  I'll assume you know how
to do that.

I think that's pretty much it.  If you have any questions please respond to
this post.  I'll receive an e-mail and try to help.  If you want to know how
to implement Tomahawk 1.1.3 into Borland's JBuilder, I can help with that
also I believe.

Navigation with dynamic URLs

2006-09-22 Thread born

Hi everybody,

I'm stuck. I have found the following URL
http://wiki.apache.org/myfaces/Custom_Navigation_Handler. The last part
(/view.jsp?objectId=#{view.objectId}) would solve my problem, but unfortunately
it doesn't work. MyFaces render this to the URL
http://localhost:8080/productPage.jsf?product_id=#{product.jsf

This is my navigation rule

*

order
/productPage.jsf?product_id=#{product.manufacturerPartNr}




Does anybody know how I can get this example running on my environment?

Thanks a lot

Re: Two dataList in same page


If the data is never going to change put it in application scope.

If the data is going to change, then you don't want to be doing it this way.

But if you want to be stubborn, write a phase-listener that happens
right before restore_view.

Re: tomahawk 1.1.3

2006-09-22 Thread JBuilderDoug


PROBLEM PRETTY MUCH SOLVED!!!

The primary thing I was doing wrong was that I was trying to implement
MyFaces and Tomahawk into an older project and it was using the JSP 1.1
specification instead of 2.0.

I created a new project in Borland's JBuilder and specified JSP 2.0.  I
initially used RI JSF provided by Borland, then substituted MyFaces and
Tomahawk.  There were a few .tld file issues after the substitution, but
after that all went pretty much as layed out on the myfaces.apache website.

I didn't need any additional entries in my faces-config.xml file and only
the filter entry specified by myfaces.apache in my web.xml file.

Tag reference sheet for Tomahawk 1.1.3 is not correct?

2006-09-22 Thread Rønnevik , Eivind




Hi 
all!
 
If I go to the tag 
reference sheet for Tomahawk and select dataScroller (http://myfaces.apache.org/tomahawk/tagreference.html#dataScroller), 
it says that the dataScroller has an onclick and an ondblclick 
attribute.
 
However, from my jsp 
I don't get these attributes displayed when getting the different attributes for 
that component.
 
The reference sheet 
is for tomahawk 1.1.3 which is the version I use as well.
 
Are there different 
versions of the tomahawk-1.1.3.jar out there, do I need to get a nightly build 
or something, or can anybody explain this? :) 
 
The images used in 
the facets have an onclick attribute, but I cannot handle the paginator if 
somebody click one of the page-numbers..
 
I also found this 
former post (http://www.mail-archive.com/users@myfaces.apache.org/msg25044.html) 
where it seems like a patch has been created to solve this issue, but how to use 
this then?
 
 
 
:)

Eivind

Re: Authorization via view-handler

2006-09-22 Thread janw


Hi Patrick,

thanks for the hints and the links.

Unless I use redirect in a navigation rule, in a filter I don't get the
destination of the request, but the source.
example: login.jsp => start.jsp
When performing the login, the information I have when filtering the
login-request is the URL of login.jsp.
But useful for me is only the requested resource. In a PhaseListener I could
access the requested view-id:

public void beforePhase(PhaseEvent phaseEvent) {
  String viewId =
phaseEvent.getFacesContext().getViewRoot().getViewId();

Then I can easily distinguish if a protected resource is requested or not.
I'll try it, though coupling the authorization to the framework.

Regards,
Jan

I've got another solution under the belt using DynaFaces which doesn't
require any customization of the navigation components. Unfortunately,
DynaFaces defect #13
(https://jsf-extensions.dev.java.net/issues/show_bug.cgi?id=13) has to

DynaFaces seems to be a very clean and efficient implementation of AJAX

RE: Run-time component generation

2006-09-22 Thread John Holland

I'm trying to do something similar using ajax4jsf.  The issue I'm having
is that my a4j:commandLinks aren't invoking their actions or
actionListeners when clicked.  The components themselves look fine and
render accordingly though.  I'm guessing that I'm missing some
initialization that needs to be taken care of when I programmatically
create the commandLinks but I'm just not sure what that is.  If you
could give me any hints on how to accomplish this (before I spend hours
figuring it out) I would be very grateful.

As far as I understood my management, we won't be releaseing it open
source. But 
of course I can share parts of the code.

 > How do you do these expanding/contracting panels?

They are actually not substracting/contracting. It's dynamic
adding/removing of 
children.

That's how it works. [+] and [-] buttons are AjaxCommandLinks with
normal images 
inside of them (see ajax4jsf library for the ajax components). They have
bound 
action handlers which know "their" panels.

When the link is clicked, ajax4jsf sends the request to the server and
action 
handler is invoked. The action handler (let's take [+] for instance)
then knows 
that he has to add new controls to his panel. These new controls are
built in 
the runtime and after that added to the corresponding panel.

The [+] AjaxCommandLink has its reRender attribute set to its panel id.
So after 
the action handler is invoked on the server side, the panel just gets 
re-rendered within the page and it showes new controls after that.

AJAX with ajax4jsf has actually minimal impact on the processing.
ajax4jsf is 
really very non-intrusive. I can change all AjaxCommandLinks back to 
HtmlCommandLinks and it will work just as well - with the exception that
the 
whole page will be reloaded on each button click.

The "tricky" part here is component creation. Well, it's also not
tricky. You 
just have to do what tags do - instantiate the components, add
value/method 
bindings, add children components or facets. Not too complex.

I am currently trying to extract business non-specific and non-critical
things 
into an open-source hifaces.dev.java.net project.

Re: Authorization via view-handler

2006-09-22 Thread Patrick Dreyer

Hi Jan

Don't do authentication/authorization through a ViewHandler, use a servlet
filter instead.
Citation from JavaWorld
(http://www.javaworld.com/javaworld/jw-07-2004/jw-0719-jsf.html):

Additionally, by using a ServletFilter the configuration keeps in web.xml and
it's a snap to force SSL for example.

There is an interesting article about page authorization in JSF on
http://jdj.sys-con.com/read/250254.htm

We generally put secured page in different directories (user role dependent) and close the whole directory with a security constraint.

To: [EMAIL PROTECTED]Hi all,I am using selectOneMenu to create a drop down, on change of the dropdown I need to display a dynamic table. When the page first loads, I do not want to display the table.
In my jsp, I have used the following code:


  
    

        

        id="tabledata"        value="#{ajaxtableform.myList}" 

        var="myItem"        binding="#{ajaxtableform.myDynamicDataTable

public class TableForm {    private List tables = null;

    private String selectedTable = null;    

    private GenericTable[] myRecords;    private String[] headers; 
    private HtmlDataTable myDynamicDataTable;

    private List myList;

        if (tables == null) {            tables = new ArrayList();
            tables.add(new SelectItem("1", "Table 1"));

            tables.add(new SelectItem("2", "Table 2"));

        }        return tables;

    }        public GenericTable tableToDisplay() {
// Getting a Null pointer exception here

        if (selectedTable.equals("1")) {            return new InventoryItem();
        }        else if (
selectedTable.equals("2")) {            return new SecondInventoryItem();

        }        else return null;

    }    

    public GenericTable[] getMyRecords() {    return myRecords;

    }    public HtmlDataTable getMyDynamicDataTable() {
    if (FacesContext.getCurrentInstance().getRenderResponse()) {

    loadMyList(); // Reload to get most recent data.    populateMyDataTable();
    }    return myDynamicDataTable;
    }

    private void loadMyList() {    

    headers = tableToDisplay().getHeaders();    

    myRecords = (selectedTable.equals("1")) ? AjaxTableDataBean.getCarInventory() : AjaxTableDataBean.getSecondInventory();

    myList = new ArrayList();    for (int i = 0; i < myRecords.length; i++) {

        myList.add(Arrays.asList(myRecords[i].getRow()));    }
    }

    private void populateMyDataTable() {        myDynamicDataTable = new HtmlDataTable();

    // Any rows?    if (myList != null && myList.size

() > 0) {    // Set columns.

    for (int i = 0; i < headers.length; i++) {    

    // Set header (optional).    UIOutput header = new UIOutput();
    header.setValue(headers[i]);

    // Set output.    UIOutput output = new UIOutput();
    ValueBinding myItem = 

    FacesContext    .getCurrentInstance()

    .getApplication()    .createValueBinding("#{myItem[" + i + "]}");
    output.setValueBinding("value", myItem);

    // Set column.

    UIColumn column = new UIColumn();    column.setHeader(header);

    column.getChildren().add(output);    

    // Add column.

    myDynamicDataTable.getChildren().add(column);    }

    }    }

    public List getMyList() {

        return myList;    }

    public void setMyList(List myList) {        this.myList = myList;
    }}

Note that the default selectedTable is null and it still tries to load the table. Due to this I get the following error:Caused by: javax.faces.el.EvaluationException

selectOneMenu queries

2006-09-22 Thread Aneesha Govil

Hi,I have some questions about the selectOneMenu. In my work on this so far, if I set the value attribute as:
and if my selectedTable property of the form bean is set to a present value in the tableform class, the change on the UI is not reflected in the class. It always works with the same value. If I set the default value to null, it works. Why is this so? 
I am facing a problem with this behaviour. If I don't set a default value, I get a null pointer exception in some functions that are called when the page first loads. If I set it to a default value, the component is not refreshed. (I am doing this using ajax4jsf). Is there supposed to be any other way to make this work?
Thanks,Aneesha

Not sure.   See below.

I'm guessing it's not provided as part of tomahawk, and that you

Yes.   Not allowed.

Yes, it has errors.  Yes, it could be the cause of the problem.
You have the extensions filter mapped five times instead of two.

Delete the one for *.faces
Delete the one for /faces/*
Keep the one for Faces Servlet
Keep the one for 
/faces/myFacesExtensionResource/*

Delete the one for *.jsf

Move the servlet-name one after the myFacesExtensionResource one.

Hey Bill,

Nice Blog :)

I've got another solution under the belt using DynaFaces which doesn't 
require any customization of the navigation components. Unfortunately, 
DynaFaces defect #13 
(https://jsf-extensions.dev.java.net/issues/show_bug.cgi?id=13) has to 
be fixed before it is readily usable.


DynaFaces seems to be a very clean and efficient implementation of AJAX 
for JSF.

I am a little unsure of your answer. The body of the content Panel,

Or is there another way to generate the component tree ?

Do me a favour and check if you have forms embedded in a form. That's
disallowed in HTML, and might be the reason for this!

Re: Accessing JSP action var attribute from normal JSP expression or action


On 8/23/06, Daniel Kröger <[EMAIL PROTECTED]> wrote:

I'm a bit confused since the description of the var attribute for the
dataTable action says it's the request scope variable that holds the
current row object.

But the following exemplary code doesn't work anyway:


   
 
 ${child.name}
   


So is there any other way to access the current var attribute from a
normal JSP expression or action?


 will work.  If it's not working,
it's probably because #{children} is wrong or empty.  Generally, it''s
#{bean.list} so what you have there looks a little odd.

${child.name} will not work.   $ searches the
jsp scope, not the JSF scope.   I think this scope is only used when
the page is compiled, but I don't use JSP.

Re: how to access a managed bean from a button action listener ?

Hithank you for reading my posthow i can access a managed bean from a button action listener ?for example i have a managed bean named session and its scope is session, i used it to store user details until he/she logout

From within an action listener, you can access a session scoped value named "foo" in a couple of different ways:(1) Use the session attributes map in external context:FacesContext context = 
FacesContext.getCurrentInstance();Map sessionAttributesMap = context.getExternalContext().getSessionMap();FooBean value = (FooBean) sessionAttributesMap.get("foo");*** NOTE:  This approach does not trigger managed bean
 creation if the bean does not already exist.(2) Use the managed bean mechanism programmatically:FacesContext context = FacesContext.getCurrentInstance();FooBean value = (FooBean)  context.getApplication
().getVariableResolver().resolveVariable("foo");This will use the same managed beans creation logic that JSF uses when resolving expressions, so it will cause the bean to be created if needed.If you're using Shale[1], by the way, there is a convenience method called getBean() in the abstract base class for view controllers that hides the grungy detail for you.

I'm using Core 1.1.4 and Tomahawk 1.1.5-snapshot (Aug 18th) myself.

Wait a little bit and see if someone more knowledgeable about
javascript comes online to help you.   I'm pretty useless when it
comes to javascript errors.
