Problem with Custom Technology Wizard in 7.5

[former_member191044]

Hello all,

I have a serious problem with the Custom Technology Wizard in the 7.5 NWDS. I was able to create the task once with my desired xsd structures but i am not able to update them anymore. The log throws the following every time i try to open the wizard:

This does not seem to happen with local DCs for some strange reason. It only happens in DCs that belong to NWDI managed tracks.

Can anyone give me a hint on this one? This is quite a horrible issue.

Many thanks.

Tobias
