reset or clear input Fields in Web Dynpro

Hi,

i created a View with severel Input Fields. Normal Text Filds and Dropdown by Index Fields and some Date Fields.

Now i wanted to give the User the ability to clear his input.

I try to use Invalidate() but this kills my Dropdown Fields.

Is there a Function that resets my fields, without destroying my Dropdown Fields?

Regards
