Databasetables viewed in 'Data Sources' (F4) show up correct, eg. a numerical value of 5.90 is localized as 5,90.
If you include the table in a spreadsheet (Data->Pivot Table->Create), all decimal-commas are displayed as decimal-points and some values are changed to a date-format. '5,90' appears as '01.05.90'. Processing these values yield strange results.
The same phenomenon exists if you replace the table by a local query or a database view.
Database is postgresql94-server remotely accessed by current JDBC-driver.
This is an upstream bug. I am able to reproduce it with the trunk version (4.2.0) on Windows.
