jasper reports - How to slide up text fields in summary band when one is empty? -

-

i have jasperreports report invoice. @ bottom of invoice in summary band, have few fields summed invoice details. standard stuff. 1 of fields "account balance", lists outstanding balance on account can add "amount due today" last line of summary section.

however, accounts don't have outstanding balance i'd skip line on invoices, move below text fields up.

how can accomplish this? using latest version of jasperreports , use groovy engine. i'm thinking somehow programmatically change position of elements, or perhaps use subreport summary?

as far understood, "line" "account balance" simple text field? set option "remove line when blank" , possibly "blank when null" remove field if it´s empty.

the following elements should have "float" setting, israel mentioned.
