FPM Dynamically Change LIST UIBB Header

Hi,

I am designing a tool where there is requirement of changing LIST UIBB headers based on Message Type.

For Eg: If user selects Message Type 1, the following headers should be displayed.

Header 1 | Header 2 | Header 3 | Header 4.

If user selects Message Type 2, the following headers should be displayed.

Header A | Header B | Header C | Header D.

I tried triggering FPM_START and FPM_REFRESH event, but did not succeed.

Any help would be highly appreciated.

Thank you,

Mahesh
