Hi,
I'm trying to build a little application using a nebula grid with setAutoHeigth(true) and a GridEditor. I Registered a MouseAdapter on the Grid and when clicking in a cell of my Grid a new SWT Text widget gets created and filled with the text of my cell. This is fine so far. But when having large amounts of Text in the cell, so that the Entire Cell cannot be shown, I'm getting to problems: When scrolling down in my grid, I can see the next row. But I can not see the remainder text of the previous row. Furthermore, I cannot activate an GridEditor on such cells: I see no cursor of my newly created editor, and I cannot type anything. Visually, everything seems like before clicking the editor.
Have I done something wrong? Or is this a Nebula-Bug?
