Matser Table/Detail Table -- Hide detail panel when no row

Question

Hi,
I would like to hide the detail panel when the user selects a row in the master table without detail.
I try to put something like this:
<af:panelHeader
rendered="#{bindings.MyView2.estimatedRowCount>0}">
But it does not work, instead the previous detail rows are display when there is no detail rows for the master row.
I need to to press a button <af:commandButton text="Apply change"/> , to render the page correctly.
The selection facet used in the master table is defined as follow:
<f:facet name="selection">
<af:tableSelectOne autoSubmit="true"></af:tableSelectOne>
</f:facet>
Where am I wrong, it is my first project with ADF ?
Any help will be appreciate,
Thanks,

Well not really clear if it's a bug or not, but here's two workarounds:
1- the table is surrounded by a panelCollection, if we add a partial trigger from the panelCollection to the table, on every change of row selection the table refreshes itself.
2- The second option was to remove the primary keys from the entity, and force it to use RowId as the primary key.
This is such a weird behavior in ADF, it's one of the basic things that one will do in an application. We tried to do a test on a smaller app and it gave the same results.
Here's the scenario:
Master/detail linked by two keys
Master PK (key1, key2)
Detail PK (key1, key2, key3) => key1 and key2 are the link between the tables.
If anyone can reproduce this and confirm if it's a bug, it would be greatly appreciated.
