Hello... I'm getting mad with this exception, I don't understand what I am doing wrong

I'm trying to update a record that has a FK field.

If I update the record when the FK is NULL, then everything goes fine, but if a FK is selected and I simply want to change it it gives me this exception.

I don't understand, why is it a problem to update this record? can you help me or you need more details? thanks

Re: ForeignKeyReferenceAlreadyHasValueException - I'm getting mad with this
I think I solved, I'm not sure how

I think that I was trying to change an object value while that was loaded somewhere else in the code.
