Re: TreeNodeChecked and t:treeCheckbox sample ?

[Wolf Benz <eu...@gmail.com>]

Hi Michael,

Thanks for this contribution!
I have a question with yr code:
Your setup is:

<t:tree2 id="serverTree" value="# 
{SearchControllerBean.treeController.treeData}"

...

<f:facet name="document">

</f:facet>

</t:tree2>

...(code:)

       treeData = new TreeNodeBase("root-folder", "All", false);

         TreeNodeBase catNode = new TreeNodeBase("categories",  
"folder1", false);

         catNode.getChildren().add(new TreeNodeChecked("document",  
"doc1, true, true));

...

         treeData.getChildren().add(catNode);



         catNode = new TreeNodeBase("categories", "folder2", false);

         catNode.getChildren().add(new TreeNodeChecked("document",  
"doc5", true));

...

         treeData.getChildren().add(catNode);

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

--> From this , I understand (correct me if I'm wrong)

- the most inner element (the leafs of the tree; "document" in yr  
case) have a name that must match the "facet"-name inside tree2 AND  
match the "type" parameter of TreenNodeChecked.

My question:

You also have a "in-between" level: the "categories"-type. Yet you do  
not declare a facet for this. When I do that, I get a "Unable to  
locate facet with the name: categories"-exception.

Did you have this too & if so, how did you avoid it?

Plus, (extrapollating the question) is there a way to specify  
attributes for levels in between?

Suppose e.g. I wanted to have folders of depth 2 to be a blue folder- 
icon, of depth 3 a yellow icon, ... (to improve visibility), is the  
way to do this just by nesting facets?

e.g.

<facet name="categories">

	<t:graphicImage value="blue-folder-closed.png" border="0"/>

	<facet name="subCategories">

		<t:graphicImage value="yellow-folder-closed.png" border="0"/>

...

	</facet>

</facet>
