Thank you for your response.
No. That is not the problem. If you read the thread you would notice that the list must be dependent on the value of the collapsblock heaeder. You need to invoke a query based service to display a list which query is based on the text value of its collapseblock header.
Just putting a list into the colapseblock item works fine. That is not the problem I am trying to resolve.
I suspect that the the problem is happening because of this console message (Again update related. It is crazy. There are no change control procedures in place to ensure backward compatibility)
CONSOLE MESSAGE: "Attr child nodes are deprecated and will be removed in M45, around August 2015. Please use 'Attr.value' instead. "
For some reason the the collapseblock is not accepting child nodes.
When I put an alert on Colapseblock EXPAND the alert loops indefinitly. The only plus is that the correct value of the header text is displayed.
