rich:treeModelAdaptor iterating arrays

[nimo22]

Can I use a simple Collection (List) of Objects for a rich:tree ?

{quote}The <rich:treeModelAdaptor> component takes an object which implements the Map or Iterable interfaces. It adds all the object entries to the parent node as child nodes .{quote}

<rich:tree>

<rich:treeModelAdaptor id="project" nodes="#{bean.list}"

var="i">

<rich:treeNode>

#{i.name}

</rich:treeNode>

</rich:treeModelAdaptor>

</rich:tree>

does not work. The iteration occurs, but I do not see the #{i.name} of a leave. However, i.name is a simple string.

By the way, the docs in http://docs.jboss.org/richfaces/latest_4_0_X/Component_Reference/en-US/html_single/#chap-Component_Reference-Trees section Example 12.4. Nested <rich:treeModelAdaptor> components uses the old <rich:treeNodesAdaptor instead of rich:treeModelAdaptor.

Okay, it was my fault, with that it works:

<rich:tree var="i"

<rich:treeModelAdaptor id="project" nodes="#{bean.list}"

<rich:treeNode

#{i.name

</rich:treeNode

</rich:treeModelAdaptor

</rich:tree>

So you see, I have to declare the var of my leaves at rich:tree and not at rich:treeModelAdapter. However, I dont understand that. According to example in rf-manual:

rich:tree>

   <rich:treeNodesAdaptor id="project" nodes="#{loaderBean.projects}" var="project">

      <rich:treeNode>

         <h:commandLink action="#{project.click}" value="Project: #{project.name}" />

      </rich:treeNode>

the var is defined within the rich:treeModelAdapter (formerly named as rich:treeNodesAdapter).

we using single var for the whole tree component for simplicity purposes in first version. hovewer it's valid request for feature(probably different level nodes definitions will be clear with separate var) if think that not convinient.

P.S. will inform doc team about current unavailability. Thanks.

And is there a way to define static label for a node ?

For example:

<rich:tree var="i>

<rich:treeModelAdaptor id="project" nodes="#{bean.list} label="myNode"/>

<rich:treeNode>

#{i.name

</rich:treeNode>

</rich:treeModelAdaptor

</rich:tree>

It should render something like this:

myNode

..->leaf

..->leaf

The problem is that I use a simple ArrayList without a key, therefore I have no node in my list (only leafs). So I iterate through the arraylist and all the leafs are shown but without a node-label, therefore I can not toggle the leafs via a node, because no root-node for my leafs is visible.

tree is dynamical by nature so we do not probide static nodes option at least for initial release. So easy way probably is to wrap your model adaptor with one more pointed to list with single object which contains "myNode"

Hi,

Use 'leaf' attribute.

[nimo22]

Using this leaf="staticText" does not work, as Ilya said, it does not work for static content, so leaf have to be a list.

<rich:tree var="i>

<rich:treeModelAdaptor id="project" nodes="#{bean.list} leaf="staticText"/>

<rich:treeNode>

#{i.name}

</rich:treeNode

</rich:treeModelAdaptor>

</rich:tree>

Would be nice, if we can build a tree by static content without the need for using a backend list.

For example:

<rich:tree>

<rich:treeNode>

<h:commandLink value="node_1" ..

    <rich:treeNode>

        <h:commandLink value="leaf_from_1" ..>

     </rich:treeNode>

..

</rich:treeNode>

<rich:treeNode>

<h:commandLink value="node_2" ..>

</rich:treeNode>

..

</rich:tree>

Actually, this is not possible. Am I right?
