If a table cell, tracked by a TableEditor, is moved in a way that doesn't affect the size or position of it's TableColumn, the tacking fails and the TableEditor Control isn't moved with the cell (this is because TableEditor only tracks movement of cells by adding a ControlListener to the relevant TableColumn). This can happen when disposing TableItems, for an example (including a workaround) compile and run the enclosed testcase.
Created attachment 37283 [details] Testcase incl. workaround Compile and run the testcase. Delete rows by using the buttons. If deleting a row causes the underlying row to be shifted up, the button isn't moved with it. Enabling the workaround makes the button move with the row correctly (by forcing a TableEditor.resize() - all the fun stuff is in the 'selector' Listener)
Created attachment 37670 [details] Testcase w. better workaround Testcase with a much nicer workaround. As far as I can see it is not possible to make TableEditor track the cell correctly in the case where a TableItem moves without changing it's TableColumn (because TableItem doesn't publish the move or resize events), at least not without hacking into the paint event and doing something nasty there. A solution could be to just update the Javadoc to mention the case where it doesn't work and perhaps the workaround.
