Hi Thomas,

I've not had this specic error myself but my colleagues and I have had numerous random errors whilst using NDS for Web Dynpro development. As a development tool it is far from stable.

What version of NDS are you using?

I'm on SP16 and found a lot of my problems went away after I downloaded and re-installed SP16 from scratch after first un-installing the original version.

Hope this helps,

Gareth.
