I just opened a table for editing when I noticed that the Forms node disappeared from the Solution Explorer window of Eclipse (see attached img) and a Data providers node was shown instead. And I could not make it reappear. I had restart the application.
This is the second time I see this happening but the first time I was just playing with Eclipse and I thought I did some mistake.
yes, I was editing a calculation. I am not able to check it now, but I am quite sure that the Forms node did not reapper after I closed the table edit view. But I will be more precise later. Thanks.
