[news.eclipse.platform] Viewer is busy

[craquerpro@xxxxxxxx (David Perez)]

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.

Any help please?
