[news.eclipse.platform] Re: Viewer is busy 
Calling viewer.add(newRow) doesn't show this problem.  :-)

I forgot to mention that the table is virtual.

Hi,

I want to add a new row in my viewer at the end.

So I have this code: 

            Table tbl = viewer.getTable();
            insertIndex = tbl.getItemCount();
            viewer.setItemCount(insertIndex+1);
            viewer.replace(newRow, insertIndex);


The problem is that it fails in the replace():

!MESSAGE Ignored reentrant call while viewer is busy. This is only logged once per viewer instance, but similar calls will still be ignored.
