[IDV #JYJ-451577]: IDV v2.9a1: Loading bundles without data source specified

> Hi Dave-

Hi Dave,
       Jeff has a fix for this, it will work as you expected. I just checked 
into the svn and should be available in the tomorrow's nightly release.

> > This time, the data source that I added in Step (1) is shown on the
