Maybe some more hints about weird behaviour...I have selection implemented as to sample in showcase, via a4j:ajax execute @this.
When I do extdt selection (via selectionlistener method), it does getrowdata() on whole 10 rows which I am displaying, so it goes to database 10 times. Why is it so? Isn't it natural to only go to database (getrowdata) for the one element, which you have selected? Should I implement some kind of caching mechanism? What is the best practice for this?
