Customer-Master form - For the Site Uses Page - Business Purpose Tab

Hi Team,

In  the Customer-Master form - For the Site Uses Page - Business Purpose Tab -

I am able to add an additional status  ALL to existing Pick list drop down by extending Controller: HzPuiAcctSitePurposesCO , that fetches both active and Inactive records at a time and was able to default ALL as the status when we open the page. BUT ADD ANOTHER ROW functionality failed to work.. On clicking add another row - Page is getting refreshed and row is not getting added.

Similarly when we change the Status it is fetching the rows accordingly, BUT when we select a Ship To or Bill To line page is getting refreshed, line is not selected  and Status is Changing Back to Default ALL.
