What version of LCDS was this written for? I can't seem to resolve
seq.getItemInfo() with my 2.5.1 jars.

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?

I just went through installing/configuring JTA using JOTM(which was
not as straight forward as the docs say) with Tomcat.
The bummer is that I can't debug into the DataServiceTransaction
class... no source.
I guess I could try passing false to the begin method, but I should
be able to use JOTM.
BTW, thanks for your help on that other LCDS issue.

Oops, I forgot that particular call was added in a 2.5.1 hotfix or also exists
in 2.6. If you comment out that line, you still see the sequenceInfo above
