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?

I am having the same problem as above. Can anyone help or provide more information about this? It seems the editor is not activated and text that go beyond the height of the grid are not displayed.

Is there a solution to get around this. Thank you.

I have the same problem as well. I think it might have to do with the following code I found
	public Rectangle getBounds(int columnIndex) {

		// HACK: The -1000,-1000 xy coordinates below are a hack to deal with
		// GridEditor issues. In
		// normal SWT Table, when an editor is created on Table and its
		// positioned in the header area
		// the header overlays the editor. Because Grid (header and everything)
		// is drawn on one
		// composite, when an editor is positioned in the header area the editor
		// overlays the header.
		// So to fix this, when the editor is anywhere its not supposed to be
		// seen (the editor
		// coordinates are determined by this getBounds) we position it out in
		// timbuktu.
		if (!isVisible())
			return new Rectangle(-1000, -1000, 0, 0);

		if (!parent.isShown(this))
			return new Rectangle(-1000, -1000, 0, 0);

		Point origin = parent.getOrigin(parent.getColumn(columnIndex), this);

		if (origin.x < 0 && parent.isRowHeaderVisible())
			return new Rectangle(-1000, -1000, 0, 0);

		Point cellSize = this.getCellSize(columnIndex);

		return new Rectangle(origin.x, origin.y, cellSize.x, cellSize.y);
