RCP project with tableviewer and remove functionality

Hi,

When using JFace TableViewer and calling TableViewer#remove on an object in the viewer, the object is removed from the view.

However, when calling refresh, the removed objects reappear in the view.

I guess this is a bug. If I am mistaken, how can I remove objects permanently? (preferably without resetting the whole input on my viewer)

I ran into that problem when using Comparators on my viewer. I resorted the input by calling refresh on my viewer and saw my deleted items reappear. 

I created a small RCP project with a view and a remove button to show the problem. 

If you'd like to reproduce it by yourself, you can create a TableViewer and simply call TableViewer#remove(object) and TableViewer#refresh(). 

Kind regards,

No. TableViewer#remove() does not remove it from the input. You also have to remove it from your input-Instance.
