Marko,
You could always override the create method for the control and make a POJO
call or use another Data set that will set a global variable.

Marko,
Attached is a report that creates two data sets.
One for offices and one for orders.
In the reports initialize method I create a global variable test.
I add two tables to the report one for each data set.
I set the visibility of the offices one to hide, this is so the query gets
called. In the offices data set methods I override the onFetch method to
set my global variable to
test = row["OFFICECODE"];
Then in the second table I set the header value to the global variable test.
There are probally better ways to do this, but here it is.
