Description Alex Thurgood 2013-01-10 16:40:56 UTC
See bug 59200 for a sample table.

The table described there had the following data displayed with the isql tool :
+----------------+-----------------------------------------+---------------+--------------------+
| type           | comments                                | action_type_id| chg_date           |
+----------------+-----------------------------------------+---------------+--------------------+
| A.94(3) EPC    | Normal examiner office action           | 1             | 0000-00-00 00:00:00|
| R.71(3) EPC    | Intention to grant communication        | 2             | 0000-00-00 00:00:00|
| R.51(6) EPC    | Notice of grant communication           | 3             | 0000-00-00 00:00:00|
+----------------+-----------------------------------------+---------------+--------------------+
SQLRowCount returns 3
3 rows fetched

1) I decided to edit the content of tuple number 3 in LO, removing the letter "n" from the word communication.

2) I then saved the change by moving up a row in the table view, or by clicking on the write to disk icon.

3) LO removes the whole character string back up to the first letter, and this change is saved to the database backend.

What should happen is that only the modified string should be saved, not more removed than was changed by the user.

Should probably mention that we're talking about a mysql database connection via ODBC.

Alex: on pc Debian x86-64 with LO Debian package 4.3.3, UnixOdbc 2.3.1-3, I don't reproduce this.

Any update with last stable LO version (4.3.5)?
