I just joined this list a few days ago, so I can't reply to any of the original messages in this thread, so hopefully this sorted appropriately. I traced the problem back to Table in the _cleanUpMetaColumns() function in 0.6.6. What happens is the following: in my application, I have a panel that basically controls a specific module that gets attached to a tab in a tabview. I don't want these panels floating around in memory, so I close them down when the tab is closed. I make use of Table/TableModel objects (quite preferable to the ListView for a number of reasons). When the user closes the tab, I dispose all objects, including the tables. We get trouble in _cleanUpMetaColumns(), which is called from dipose() when Table attempts to remove the paneScroller object from this._scrollerParent (line 506). For whatever reason, paneScroller is already disposed and thus we get an error when it gets down to the nittygritty. I don't really know why the paneScrollers are already disposed at this point (I don't see where else they could have been disposed and I know I'm not disposing them manually), but it must happen at some point before _cleanUpMetaColumns(0) is reached in Table.dispose(). I'll leave that for others to discover. I have a work-around, however. Right before you dispose your Table object, call the following: myTable._cleanUpMetaColumns(0); At the very least, it removed the errors in my case.
