Hello, I have the exact same issue you described as your first problem: when opening a new context, in serverscript, it's giving me the error: Could not convert variant of type (UnicodeString) into type (Integer). This must be something in the database, but i can't find it (i disabled the custom code). Keygen is also incremented. In the SYS tables i can't find anything unusual. For me it's only the entity Opportunity. It happens the latest build of 11.2. I was wondering if you already found a solution for this? Maybe R&D can help us with pinpointing where to check or what the error means.
