Hi guys -I'm working on a hard-to-trace down AttributeError thrown when I try to objectstore.refresh() one of my central objects. I've created a trial test case, which sadly _does_not_fail_, but at least demonstrates my usage. I'm looking for angles to approach this problem from; sadly the object I'm trying to refresh isn't portable, nor does it lend itself towards simplification.
In short (and English), after updating one of my secondary instances that has a foreignkey relationship with my customer instance, I commit the objectstore (which happens successfully), and then refresh the customer. With full echoing turned on I see the update occur, and the select get issued for the refresh. It is immediately after the SELECT that the error occurs, at line 414 of attributes.py in reset_history.
I tried haphazardly throwing refresh(cust) calls at various places, but was only able to evoke the error by refreshing the object after the commit().
Any ideas? --G
