ALV BLOCK: status GUI

Hi great people,

I'm figthing with the status GUI of an ALV Block since yesterday.

I have an ALV with 5 blocks. I defined a status GUI with some buttons, and the point is that some of them (as Select and Unselect all) works ok. But there are some of them that when I pressed it ends in a dump.

I debbug them and I noticed that those bouttons that ends in a dump "are refering" to a standard program (SAPLSALV) and not to the Z one. I mean that the parameter I_CALLBACK_PROGRAM, when I press the button, in those cases has the value SAPLSALV and not my Z program. I checked and I'm passing the program name everywhere I have to.

Any idea?

Thanks & regards.
