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.

I forgot to mention that the table is virtual.

Calling viewer.add(newRow) doesn't show this problem. :-)

The problem with this alternative is that the viewer isn't updated.
Any hint from viewer gurus please...

Could you please file a bug for this, ideally with a snippet with which we
can reproduce the problem?

Thanks
Boris

Thanks Boris for your interest, I think I have solved it.
I have rewritten my code, and I don't have this problem anymore. :-)

I have run into the same problem with the replace(element, index) method on AbstractTableViewer. Can you post your work around here?

Thanks,
