Another generic error message, this time in project #11982 (I've shared this with Max). The screen titled "Welcome - Logged In" uses a Working Area. Every time the project is opened, the Working Area shrinks into the upper left corner and cuts off much of the content of the screen. Saving after an adjustment to it does not fix the problem.
And doing a web preview of the screen results in a generic error message.
Looking into this...
Looks like a bug. Can you tell us what steps you did to place a Working Area container on a non-template page (just a regular screen)? This will help us fix the bug.
I'm not sure exactly how this student did this. It appears that the page was originally derived from the "Master" template, but then he tried to break it apart from the template and the Working Area didn't convert to a Panel as it should have. ?? I've asked for more details, but I'm going to guess he can't replicate his steps.
This should be fixed in tomorrow's release.
We fixed this problem in your project (updated the XML). Please try it again. We also fixed it as a general bug.
