Custom Pop up displaying Blank page

Hi,

I am trying to open a custom view as popup from BT115IT_SLSO component. I have default view configuration correctly set and it is displaying the attributes correctly. but all of a sudden the pop is appearing BLANK. I have debugged DO_CONFIG_DETERMINATION and DO_PREPARE_OUTPUT methods and .htm page. Everything looks fine.

All other custom popups are opening correctly. But somehow this one popup is appearing Blank. Any thoughts? Please advice.

thank you

Anji
