[Trinidad] How to set initial disclosed and selected nodes?

[Stephen Friedrich <tr...@eekboom.com>]

On initial rendering my tree has to have a certain path expanded and the leaf´node selected.
I can control the expansion/selection like this:
<tr:tree disclosedRowKeys="#{productChartTree.disclosedRowKeySet}"
          selectedRowKeys="#{productChartTree.selectedRowKeySet}"
However in that case the expansion/selection state is _always_ determined by the backing bean,
but I just want to set the initial states.

This has no effect at all
<tr:tree focusRowKey="#{productChartTree.focusRowKey}"
          initiallyExpanded="true"
          ...>

I could set the state programmatically on the server side, but my problem is getting access
to the tree at the right time.

Thanks in advance for any comments.
