RE: a issue about type binding

[Tony Herstell]

When using the contrib:TreeView component it works fine, in my app, with the
example John Reynolds gave on the internet using a String.

This however does not work when I rework it to use an Object. It only ever
renders the root element and clicking on it does nothing...

Is there a problem with using objects are apposed to Strings with
SimpleTreeModel?


Sooooo similar:

    <component id="treeView" type="contrib:TreeView">
        <binding name="treeModel" expression='treeModel'/>
        <binding name="treeStateListener" expression='treeStateListener'/>
    </component>

    <component id="treeDataView" type="contrib:TreeDataView">
        <binding name="treeView" expression='components.treeView'/>
        <binding name="value" expression='value'/>
    </component>

    <component id="treeNodeView" type="contrib:TreeNodeView">
        <binding name="treeDataView" expression='components.treeDataView'/>
        <binding name="makeNodeDirect" expression="true"/>
    </component>



    <component id="organisationTreeView" type="contrib:TreeView">
        <binding name="treeModel" expression='organisationSimpleTreeModel'/>
        <binding name="treeStateListener"
expression='organisationTreeStateListener'/>
    </component>

    <component id="organisationTreeDataView" type="contrib:TreeDataView">
        <binding name="treeView"
expression='components.organisationTreeView'/>
        <binding name="value" expression='value'/>
    </component>

    <component id="organisationTreeNodeView" type="contrib:TreeNodeView">
        <binding name="treeDataView"
expression='components.organisationTreeDataView'/>
        <binding name="makeNodeDirect" expression="true"/>
