Changing Length property in Table Designer should not trigger data removal because it is not needed by database internals (even SQLite). Reproducible: Always Steps to Reproduce: 1. Open a table with at least one text field in Design view 2. Change the Length property 3. Save the table design Actual Results: Data removal is requsted. Expected Results: Changes should be silently applied. Treat this as a special during saving. Backport to 2.4.3 as a workaround for limited default length ==200 characters what relates to bugs like https://bugs.kde.org/show_bug.cgi?id=301136. This way complex workarounds like http://community.kde.org/Kexi/Releases/Kexi_2.4/Workaround_301136 will not be needed anymore - users will be able to change the property easily.
