If I understand correctly your description, those are not bugs.
BINDING an item from a DB is going through the description of this item in the analysis.
No analysis = no binding
Queries that are listed as available data sources are ALSO linked to the analysis (ie made with the query editor and based on the analysis), so pnce again, no analysis, no queries available as sources of report...
if you CHOOSE to NOT USE the analysis, then there are many tools and options that become unavailable...
