At this moment whenever you make any type of change to table's design (let's say to make a field to be mandatory or just adding a new field) all the data in that table is deleted. This is really a problem when combined with importing content from external data (such as csv files) where there's no way to make a field unique, mandatory, etc... Reproducible: Always Actual Results: All the existing data in the table is deleted Expected Results: Either: 1: promt user to keep or dele the existing data 2: mantain the data
Dear Carlos, thanks for the good request! This feature was in development for a long time, setting this wish as duplicate of https://bugs.kde.org/show_bug.cgi?id=125253. I plan to have simple option: altering some physical properties would require immediate saving of the design but will not remove all the data. Other properties would be enabled for modification even without that. Hopefully for 2.6. *** This bug has been marked as a duplicate of bug 125253 ***
