NWBC PFCG Webdynpro with standard theme in URL doesn't load the theme

Hi,

I am using NWBC 5.0 PL13

I have configured a custom theme in theme designer.

I don't want to use this them for other webdynpro applications launched in NWBC for desktop.

Therefore, in PFCG role, I have given "sap_corbu" theme in URL of webdynpro application. But this doesn't work, as the webdypro application is still taking the parameters from theme designer and not the theme "sap_corbu" ... (eg: Text colour is not black, but white which is given in theme designer)

Best Regards,

Uday
