RAP Table Update problem [message #5897]

Hi,

first I like to say that RAP is a realy a cool project!

I installed the M2 release in Eclipse to play around a little bit with RAP.
I modified the DemoTableViewPart to fetch data via a SOAP Request. That
works
fine but I can't refresh the table after the Request. I used the eclipse
debugger to inspect the contents of the underlaying table data model. The
data changed after the SOAP request but the view does not refresh. I tried

viewer.setInput(this);
viewer.refresh(this);

I must say that I am not that familar with RWT/SWT.

Any hint would be appreciated.

Best Regards,
Thomas

Hi Thomas,

unfortunately, the current Table implementation is very limited. We are
in the process of re-implementing it.
In the meanwhile the only way to refresh a table is to recreate it. In
Your case that would mean to also recreate the TableViewer.

Cheers
Rüdiger

Hi Thomas,

This is a known bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=175651

We are currently working on a new table (client side and
LifeCycleAdapter) that will solve the problem, this is one of the main
working areas for M3.

As a (quite ugly) workaround: delete and recreate the table when the
data has been changed:

if( viewer != null ) {
IContentProvider oldProvider = viewer.getContentProvider();
if( oldProvider != null ) {
oldProvider.dispose();
}
viewer.getTable().dispose();
}
viewer = new TableViewer( parent );
viewer.setContentProvider( new ViewContentProvider( id ) );
viewer.setLabelProvider( new ViewLabelProvider() );

Best Regards,

Jochen
