Hi, we get a lot of log errors like the one pasted below, complaining about an XPATH / database retrieve where non-persistable entities are involved, which, of course, is not possible. There is no clue however what the circumstances are or the user actions causing the problem. We cannot reproduce, it just happens a lot. Where do we need to look? Microflows? Pages? Certain elements on pages? Something else? Why is Mendix creating an impossible database query we didn't ask for and then bitching about it in the log?
