sum & product models hanging sasview (Trac #766) #880
Description
on creating a new sum or product model, an _user is being appended to the name, this causes a hang. Trace back below.
Andrew thinks that (a) a new model is created on compilation, (b) it gets written to disk, (c) on being reloaded it conflicts with the one already in memory. [It does cleverly seem to update the models list without having to do "load plugin models", but perhaps that is the weak point?]
If close sasview and start a new session, the newly created model works fine, without any _user appended to the name.
Traceback (most recent call last):
