Trouble with Appplication after modifying WebDynpro Theme

Hi all,

since I modified a WebDynpro theme the behaviour of several UI Elements changed dramatically.

The dropdown listbox is unclickable.

The little calendar pop up of an input field being bound to the type date doesn't appear anymore.

Basically every interactive Element refuses to be interactive 😊

I'm using a Viewset with T-Layout. The left column only contains links to views being displayed in the right column of the viewset.

This afternoon even the links do not work anymore.

I'm developing on SP12, Themeeditor and themes are as well based on SP12.

Can anybody support me?

Thanks a mill in advance,

Otto
