Hi again,
It must be the Word injection stuff. We will need to fix qRules to handle that scenario. In the meantime, it's probably easy for you to manually add the xd namespace to the form. You'll have to create a new folder and export the blank xsn as source files (see button at bottom of File->Publish section). Open up the folder that has the source files and open sampledata.xml. Search for the xd namespace declaration at the top of the file (xmlns:xd="http://schemas.microsoft.com/office/infopath/2003"). Do the same export for the Word injected XSN (but choose a different folder) and copy the xd definition into the sampledata.xml for that form. You'll need to do the same thing for manifest.xsf (search for xmlns:xd and find it at the top) and the view1.xsl. When you are done, right click on the manifest.xsf and choose Design. Save that as an XSN file (not source files) and retry the injection.
I haven't verified that this works, but it should. I will assign this to someone to do so tomorrow.
Thanks for your patience,
