Yesterday a new version of Jenkins Testopia Plug-in was released. This version includes code to avoid printing null when a value returned from Testopia is null. Instead, it now prints an empty String (i.e.: “”).
It has been included i18n support too, with English, Brazilian Portuguese and Dutch (thanks to Peter Florijn) languages. If you use Testopia Plug-in and would like to contribute translating the plug-in, send a pull request.
Check the latest changes and read more about the plug-in on its Wiki page.
