SRM iViews - No Popup after clicking buttons

Hi there,

we deployed SAP SRM 7.0 Business Package in SAP EP Portal. We rearranged iViews and put them into our own roles.

Additionally we use our own Light Framework.

Within the iViews there are buttons. Pressing a button results in a popup with the corresponding iView.

With the standard portal desktop everything works fine. The popup with the iView appears.

But in our own light framework the popup doesn't work anymore. No JavaScript errors pop up.

Did anyone have the same problem or has an idea what the problem might be?

Thanks in advance

Joschi
