ADF11g: methodAction being invoked multiple times without control...

Question

Hi,
I have a page that displays different data took from a single data control.
This datacontrol is invoked by a methodAction, and the resulting bean contains both plain attributes and List of objects.
I created my page with JDev 11.1.1.3.0, using drag and drop.
What happens (seeing the log files) is that the page calls multiple times the methodAction instead of "recognizing" it only needs to call it 1 time to have all the data bound to the page,
and of course the page does not work. I don't see the data even if the dataControls retrieve it.
Here is my code:

Can someone point me out to the solution ? Why methodAction is called multiple times ?

Answer 1

Does someone has any clues ?!
