First, you need to increase the size of the database field. That would be
- class_suffix column of the class_ table (40 chars by default) for the class external id that can be edited on the Class Setup page
- subject_area_abbreviation column of the subject_area table (40 chars by default) for the subject area abbreviation
Second, you need to update the appropriate size in the Hibernate model
(We also have the sizes in the hmb.xml files, e.g.,
PreferenceGroup.hbm.xml for the class_suffix, but these are only used to generate the Hibernate model -- ant create-model.)
Third, the user interface needs to be updated to allow longer texts
