Dynamic load of rich tree fails with RichFaces 3.3.3.Final version and Seam 2.2.1.Final version

[naveenm]

Hello,

I'm using Seam 2.2.1.Final version, richfaces 3.3.3.Final version and JSF 1.2_12-b01-FCS.

I'm facing an issue with loading rich:tree dynamically on select of a rich:comboBox, when I select a value on combobox I need to load the rich tree and render it, but apparently the rich:tree rendering is not happening. The same use case works fine with Seam 1.2.1.GA version, richfaces 3.3.3.Final version and JSF 1.2_12-b01-FCS. I'm deploying my code on Weblogic 10g.

Does anyone how to resolve this issue?

Thanks,

Naveen

Can someone please help with this issue?

Hi Naveen,

Try removing duplicate declarations for FaceletViewHandler and TreeTestAction and check.

Also I have a question: do you see tree first and then it disappears after Ajax re-render or it doesn't show up initialiy?

Hi Nick,

Thanks for your response.

The tree never gets redender. I wanted to render the tree basing on a selection from the drop down through ajax. When I debug the request comes to my bean and returns the tree node but it never renders the tree, so I put a wait status just to see if the response is coming back and the status bar goes way, but it doesn't seems the response is getting back and the status bar remains there.

BTW I removed the duplicate declarations for FaceletViewHandler and TreeTestAction but the issue still persists.

Please help.

Thanks,

Naveen

Are you using WAR or EAR?

[naveenm]

I tried by deploying as a WAR and also as an EAR and it's the same issue.

After pasting the code into Eclipse I've found the problem - you are not initializing 'rootNode' field.

[naveenm]

I tried to initialize rootNode but it didn't help.

Here is the I tried by placing in TreeTestAction.java

private TreeNode<String> rootNode = new TreeNodeImpl<String>();

Please post the updated code.

Hi Nick, I'm not able to copy paste the on to the richfaces forums, not sure why it's not allowing me to do that.

But here are the changes I made:

Change 1:

TreeTestAction.java

-----------------------------------------

1. I removed the @Name annotation

2. Replace private TreeNode rootNode; with  private TreeNode rootNode = new TreeNodeImpl();

Change 2:

faces-config.xml

----------------------------------------

1. Removed FaceletViewHandler declaration. (As pointed earlier it's still there in the web.xml only removed from faces-config.xml)

The rest of the code is the same as I posted at this forum: http://seamframework.org/Community/DynamicLoadOfRichTreeFailsWithSeam221FinalVersionAndRichfaces333FinalVersion

Thanks,

Naveen,

But it's not initialized then! Here is the code as it should be:

    public TreeNode<String> getTreeHierarchies() {

        rootNode = new TreeNodeImpl<String>();

        TreeNodeImpl<String> subNode1 = new TreeNodeImpl<String>();

        subNode1.setData("Test1");

        rootNode.addChild("Test Child1", subNode1);

        TreeNodeImpl<String> subNode2 = new TreeNodeImpl<String>();

        subNode2.setData("Test2");

        rootNode.addChild("Test Child2", subNode2);

        return rootNode;

    }

Hi Nick,

I tried that too, it's still the same issue. I noticed one thing that when I invoke the page, it's calling the getTreeHierarchies() method on the TreeTestAction, but I am not really trying to invoke that method until I select a value in the drop down, and when I select a value in the drop down it again invokes the getTreeHierarchies() method, do you think this could be causing anything?

Thanks,

Naveen

[nbelaevski]

By your code I see that dropdown value and tree value are not connected so I don't think that's the problem.

I've copied your code to working Seam project and it didn't work due to wrong initialization code in the bean; after I did the change it worked properly.

So I cannot reproduce the problem and need to ask you for small example project that will reproduce the issue at my side.

Hi Nick,

Can you please add the below action in the MyXhtml for the a4j:support tag under rich:comboBox id="secondSelection"

action="#{treeTestAction.getTreeHierarchies()}"

Now on selection of a value from the drop down should show the tree.

Thanks,

Naveen
