Could you please describe the bug a little bit more? What are you doing; what are you expecting, what Base should do; what do you mean with "class name"; how do you contact with MySQL ...

@Lionel - any opinions on this really old enhancement request?

I assume this is about connecting through JDBC, and the Java class name. It is a valid usabiity enhancement. Not only for MySQL, but for JDBC in general.

Test class name:
- m_aJavaDriver
http://opengrok.libreoffice.org/xref/core/dbaccess/source/ui/dlg/ConnectionPage.cxx#313
- m_aEDDriverClass
http://opengrok.libreoffice.org/xref/core/dbaccess/source/ui/dlg/detailpages.cxx#576

For Wizard: m_aETDriverClass
- http://opengrok.libreoffice.org/xref/core/dbaccess/source/ui/dlg/DBSetupConnectionPages.cxx#505
- http://opengrok.libreoffice.org/xref/core/dbaccess/source/ui/dlg/DBSetupConnectionPages.cxx#614

fdo#68341 Remove space of java class when testing class



The patch should be included in the daily builds available at
http://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More

Affected users are encouraged to test the fix and report feedback.

While the committed patch is good progress on this bug, I disagree that it is fully fixed. The spaces are trimmed only when one presses the "Test" button. If one does not press the "test" button, but only the "next" button, the class name is not space-trimmed.
