New/different page for different organization IDs in Jaspersoft report - jasper-reports

Question

I'm looking for any suggestions on how to print a new/different page for different organization IDs. I created a jaspersoft grouping and was thinking of adding a print when expression to the organization ID group header. Would that be the way to go? Can anyone help me with the expression that I would need for that?

Answer 1

"Start New Page" (isStartNewPage="true") in the Appearance tab of the Properties for the Group Header is all that is necessary to start on a new page for every new group. Group Expression for your situation would simply be something like $F{organizationID}.
Here's an example that groups on $F{city}, lists $F{CustomerID} and starts a new page for every new $F{city}:
