FPM : Problem in LIST UIBB (Dynamic columns)

Hi all,

i have a problem with my LIST UIBB. This list has max 40 columns available.

I'll describe the problem here :

1) The first step is to display data with 39 columns for example (it works correctly)

2) The second step is to display data with 8 columns and it works correctly too

3) The last step is to display data with 40 columns (max available columns) but it does not work correctly....just 39 columns are being displayed.....

Is there a buffer problem at first display?

How can i solve this problem,please?

Thanks in advance.

Regards.

Dario.
