Greetings,

1. At some point of time T1, an event is generated by a custom widget:

var req = org.eclipse.swt.Request.getInstance();
req.addParameter( this._id + ".addedItems", s );
req.send();

2. Then it comes to LCA:

String addedItems= WidgetLCAUtil.readPropertyValue(widget,
"addedItems");
if (null != addedItems && addedItems.length()>0)
{
widget.onItemsReceived(addedItems);
}

3. I want to add the received items to TableViewer:

protected void onItemsReceived(String items)
{
String[] input = items.split(',');
tableViewer.setInput(input);
}

4. I can't see the items I wanted to be displayed by tableViewer.
However I checked with Firebug and discovered that the tableViewer
contains empty DIV's, as many as there are items.

What can I do to make tableViewer resolving the items?

Cheers,
Dmitry

Well, asyncExec'ing the call to setInput seems to be taking this problem
off.
