In the following thread, we discussed about a bug in the way BlackPearl Data Connections are referenced in Infopath forms.

Isn't there any Blackpearl update for this particular issue? It's particularly annoying to manually edit the manifest.xsf and then re-publish the form each time the process is deployed. Moreover I suppose it's not a complicated bug to solve (just a "/" to remove in the references, cf the thread).
