I get the error: “The definition of the field GPS was changed after the object was saved. Old type: Integer New type: Decimal” GPS is a field we added. I know it’s not recommended to change the type of a field, but we did. [:(] I get this error in a report. I know in a form you have to delete the field GFS and insert it again and then the problem is solved. I made a .txt export of the report and searched for GPS and didn’t find anything. I imported the .txt file hoping this would solve the problem. But it didn’t. Then I searched in all our changed objects for GPS. I found 5 objects and I compiled them all. Without any errors. So still the problem remains. During writing this post to ask for a solution I found the solution… [:D] So this post becomes a tip. The solution is/was; Run every object until there’s no object left with the error. Eventually it was a form in which the field GPS had to be inserted again. Like I suggested myself above. [:I]
