Comment 1 for bug 329238

The error message does need fixing. It needs to state that a valid product series was not provided.

Using the <choose>, and searching for 'tao', I can see that there are no releases registered for taoframework with 'tao' in them. Searching for taoframework, in launchpad, I do not see taoframework registered as a project.

To link a sourcepackage to an upstream project, someone must first register the project taoframework so that Launchpad can track it. In addition, someone must create a series (release series) to track the releases of the project.
The series will appear in the <Choose> popup.
