I have first created a database with a profile (default):
In this profile, two <placement tags in the SAME SCREEN where filed with codes=:
They looked different. No error while creation of the database.
Then I have exported the profile for the next evolution.
The new profile does not import as the two previous tags had been truncated to 30 characters :
They are now identical and do not match the xsd rules.
During the process of creation of Userinterfaces, perharps should there be a test in order to verifiy that the truncature of placement tag code to 30 characters is unique in the same screen.
