Dear all, I am getting a run time Nullpointerexception… though I know very well what that is, it seems there is no clue to be got from the stack trace about how to fix this in Mendix (see below). Any suggestions? Redeploying to another team server is not an option due to stakeholder presence. Hope you can help. Thanks beforehand.
