During a Table usage (ICEPushed some data) I was unwary and produced NullPointerException. The problem is that there was no output, so it took some time while I discovered the exact reason. Application class seems to have an ErrorListener, I suppose this should have caught NPE. I wonder if this expectation is right and that handler is really meant for that kind of work?
Re-reading a post I see it ambiguously worded. Here is some correction: Data was pushed to the table, but there was no update visible. There was no error thrown neither. I had to try/catch around the suspected code to realize there was an NPE going on.
