For sum/multiply (including P*S) models which are still in the old !SasView infrastructure a pop up with the traceback ... which is extremely confusing to the user and not helpful. For regular models that use the sasmodels infrastructure, a message is sent to the console stating that no values were returned from the fitter and a warning that fitting did not converge. Also the corner of the console line goes red. However the console line stays blank. The first issue will get resolved when the sum/multiply get moved to the product model in the sasmodels infrastructure. Two other things are being requested in order to make this useful: * Send the message also to a popup * To the ""fitting did not converge"" add some suggestions for what might help such as ""you might want to check your starting parameters""",defect,new,major,SasView 5.0.0,SasView,,,,SasView Bug Fixing
