Page change when fieldvalue changes

[keinname]

Hello,

I'm new with iReport and Java but want to try the following:

I have a report with article-data and want to get a page change, every time a special field has a different value then before.

In other words: In the detail-band theres a field $F{lg_nr} wich changes every x articles. Now I want the report to notice the new value and insert a page change.

Is there a way to do that?

Thanks for your help.
