Implicit EL variable problem - uiComponent always evaluates to null

[dpaterson.dpaterson.convexsolutions.com]

Documentation - 7.10. Conversational components and JSF component bindings mentions this implicit variable for accessing component properties in pages but when I use this syntax on a page it always evaluates to null.

example:

<h:outputText value="#{uiComponent['some_table'].rowCount}"/>

Does <h:outputText value="#{uiComponent['some_table'].rowIndex}"/> work if you are inside of the h:dataTable?  If so, try also putting <h:outputText value="#{uiComponent['some_table'].rowCount}"/> in the dataTable.

Is it possible that you have to do something like?

<h:outputText value="#{uiComponent['parent_container:some_table'].rowCount}"/>

just a guess.

Probably not as the actual id of the UIComponent is set to what the id is defined as, or generated as.  It is possible the lookup function takes into account the id of the parent, but most likely not.
