Error in WDA when started through browser, not in SAP Workbench

Hey,

I'm creating a WebDynpro Application which should reset the password of a user.

When I start it in the SAP Workbench to test the application it works fine.

But when I start it in the browser it opens as it should but when I push the button for the new password it shows an error while the password creation.

Problem is I don't know how to debug this issue. An external breakpoint didn't work, only while started in SAP but there everything works fine so I don't need to debug here.

Does anybody got an idea why the application fails when started through the browser (outside SAP) and how I can debug this issue?

Thanks for any hints!

Regards
