*******************
My problem is when listgrid always auto save when transfered to right grid i cannot get the data which no pk to call Hibernate.SaveOrUpdate(Object)
So i want to save myself when press a save button and got pk from hibernate to retrieve to the record after.

Can anyone help me how to do that thing?

Thank you

Sorry for bad english.

Same problem here:

destination.setAutoSaveEdits(false)
destination.transferSelectedData(source);

The call to transferSelectedData() triggers an update, but I like to do a mass update later.

What are we missing?

Maybe the solution is hidden in this showcase:
http://www.smartclient.com/smartgwtee/showcase/#hbRelationOneToMany

i.e.
destination.setSaveLocally(true);
