Where is the .java file in the source code for function select Print Format?

[Lâm Kim Ngọc]

Hello everyone,

I have a prolem with report. As you can see in the picture, when click on select Print Format there are 3 options: blank(cover in rectagle red line), InventoryList Report IT and temp_table.

The problem is before clicking on Start button I want to make sure that the Print Format must be selected and don't allow select blank(disable it or if blank is selected then the report automatically select some default Print Format). Where exactly is the .java file in the source code control this? I think this footer area is defined in org.adempiere.ui.zk package but I can't find anything else related to Print Format.

Sorry for my bad English, I'm looking forward to receiving some responses in this group :D
