Context Error after Model-Reimport

Hi,

after a model-reimport (adding a 5th column to an existing model parameter) i get an error during runtime.

I did build/rebuild/deploy the DC and the modelDC.

Still I get this error.

In NWDS I can see the new column (in DC and in the model DC), build runs fine, but during runtime I crashes with the follwing internal server error:

Seems to crash on context-initialization, but I don't have a clue ...

Any idea what's wrong? Any help is appreciated.

TIA
