I was experimenting with using an empty facet as a placeholder so my
renderer knew where to insert something. Specifically, I am working
on a TreeTableRenderer and I thought marking a column with a facet
name of "tree" to indicate where the tree shoudl be rendered.
<h:column>
<f:facet name="tree"/>
</h:column>
I discovered during rendering that the facet map for the column was
null! Then if I switched to:
<h:column>
<f:facet name="tree">
<h:outputText value=""/>
</f:facet>
</h:column>
I could retrieve the facet. Interesting ... This is probably the way
its supposed to work but just thought I would pass that discovery
along. I guess facet itself is just a key by which to store the
component inside the facet tag. Makes sense.
