I pass false to my begin() method and that stops the
DataServiceException from happening, but now nothing seems to happen
after I commit(). Here's a current code snippet:
DataServiceTransaction dst = DataServiceTransaction.begin(false);
dst.refreshFill("myTasks", null);
dst.commit();
The destination parameter for refreshFill(), is that the same string
as the parameter I pass to the DataService constructor in ActionScript
and the name of the <destination> I set up in data-management-config.xml?
(i.e.
__ds = new DataService("myTasks");
<destination id="myTasks">
)
I would expect to get a hit on the fill() method in my Assembler after
the commit() is called, but I ain't gettin' nut'in.
Ideas?
Thanks,
Geoff
