I'm not sure that you can, but try to assign to a subreport parameter a report variable, try to set in the subreport the parameter to a variable and change the variable value. If all values are assigned by reference your master variable is now changed.

When i try the example. i've encountered some problems. It seems that IReport dont support java.util.HashMap (I assumed this because there's no HashMap in the dropdown list, please correct me if i'm wrong)

 

the thing that confused me even more is that when i write it manually it work in the master report. but not in the child report. Can You Tell me whats wrong?

 

TIA

RE: Subreport Return Value?

2004-03-28 14:39

you can use iReport to return values from a subreport using the hashmap method described in teodords "Returning values from a subreport" post in the jasper forums here: https://sourceforge.net/forum/message.php?msg_id=1746736

 

You will need to manually type in the Paramater type of java.util.Map over the top of the drop down box in iReport.

the provided link for solution cannot be accessed for some reason. Could anybody provide an answer for this question? I am facing the exact issue described in the thead. I am trying to sum up the value returned from various sub reports and assign it to the master variable. However, the value seems to be reset on each group for some reason even though i didn't specify the reset for this variable. Could someone please help?
