The APEX team came up with a temporary fix for this issue. Please visit this forum posting for all the updates on the issue. Basically, you need to run a small function on page load. The solution is also described there.
By the way this is one of the three bugs I have discovered so far.
Do you want to use the new Universal Theme for your existing applications? Then you should definitely have a look at the Universal Theme Migration Guide my colleagues Shakeeb Rahman and Tim Chambers have just published.
The problem I described here is strange. In my case and I tested it on several laptops with many browsers and multiple installations, appears to be a Universal Theme related bug and occurs in some specific constellation - in my case on Windows 8.1 running FireFox or Google Chrome (IE11 works as expected).

Just started a new version of My Demo Application - based on APEX 5.0 and Universal Theme. There, I will rework the old content and provide some interesting new possibilities (as of 4.2). In this example I am showing how to change the column type from Text to Display in a tabular form.
I prefer using PL/SQL Function Returning Error Text while creating validations. Two days ago I discovered a bug - it is not possible to create the function if no error message entered. This bug has been documented and will probably be fixed in 5.1. The workaround is to enter a dummy text like "ERROR" or similar.
