I compiled dbviewer from the SDK as a starting point for learning about the dataview module, but something is wrong with the code somewhere.

Running the provided dbviewer.maxpat, everything appears to be ok. If I create a new patcher and create dbviewer as a new object, it's fine too. When I save this patcher and reopen it, it crashes (on the call to maxsqlite_createview()). I'm guessing some things are initialized properly in dbviewer.maxpat, which aren't set correctly when you just create the object on its own.

In my first attempt I tried to take out the database part of the code, and my external crashed on jbox_new(), which seemed odd since I didn't touch the jgraphics part of the code.

Is there a better / different example (without the database stuff) of dataview in action?
