TableView and listCleared

Hi,

I have created a custom List that is used as the TableViews table data. 
Sometimes the list will completely change and so the list issues listCleared() 
to the list listeners. The TableView queries the list for the number of items 
in the list but doesn't display any new items if the number of list items is 
now larger.

Am I using listCleared in the wrong context or is this a bug?

Thanks,

Scott.

Hi Scott,

This bug was accidentally introduced by me in change 809678.  It's fixed
now.  Sorry for the inconvenience.

Thanks Greg,

After the update from SVN there is now an error occuring while processing the 
styles element.

Possibly a little of both. The TableView skin was incorrectly calling repaintComponent() in response to a list cleared event, when it should have been calling invalidateComponent(). This is now fixed.

However, the implication of firing listCleared() is that the list is now empty (i.e. getLength() should return 0). If this is not the case, you should fire itemInserted() events for any items added when the list is repopulated. That will correctly invalidate the TableView and the new items should appear.
