This is a very quick tip when you encounter errors in the AppTester that you don’t understand. Most obvious errors that you encounter are a mismatch between the AppTester and the IBM BAW development version. As you develop in the designer in BAW, you save edited work in between, or it is auto-saved.
The AppTester does not automatically detect changes, and works with a version that you or your colleague imported by doing a “TIP refresh”. The “TIP refresh” button at the top imports the latest work from IBM BAW. If there are a lot of changes in BAW for your project, then it could be the AppTester is trying to reach objects in the current Process App that are changed or even deleted.
So to be sure, whenever you go to the AppTester project, hit the refresh button on top of the screen and refresh your TIP!
