Form issue - data getting deleted when move out of tab

Hi,

HI,

Here are 2 tabs Mail & News in my form fmb file. If we have any atzs present for the zip information present in any of the tabs it should enable and display the atz info for them.

The data for mail and news is coming from same view -  based on DETAIL_TYPE='M' or ‘N’ (mail or news).

And atz information is populated from another view. I am calling the same ATZ data block in both tabs. I use the same joins too.

Issue:  The atz is getting populated for News where as for mails tab, its showing list of all atzs at first time(select * from atz and no where condition passing through) where as when you go to other tab and come back to mail tab again second time it is getting nulled off means its showing empty data.
