i made some extra checks for this.

But when and how do you get this behavior?  
Do you get it immediately? So you open a solution, go to form x and change some data and bang the nullpointer?

I’m getting this error when I try to set a value to a global field.  
This global field is used in relation.

This error is happening two times per session after that the solution is working as expected.
