Hello. I've downloaded and installed the snapshot as of today (8/31/2009) and, using the designer:

6. Create a "purchasing" View Model and, with "purchasing" selected, created an "example" BaseTable. I then drag-and-drop "client" from clients.xmi Source Model into SOURCES pane. (This View abstraction turns out not to be the problem -- I query the Source via the
Execute'd VDB with the same outcome.)

Is there something goofy with the equality operator against XML data? Is there flag that needs flipped on these attributes? I went with the "string" mapping on the 'XML Schema as Relational Source Model' dialog wizard (pane 4 IIRC).
Oughtn't I have? I also changed XML node names that might
have been SQL keywords ('name' -> 'fullname') but no
dice...
