A case of a mysteriously stalling grok.Container

Rate this Message:
I am not getting any errors and I am having difficulties narrowing
down the problem but... In a view, I am doing a simple: self.context['a_container']['myId_x'] ≈ an_object then I delete the object del self.context['a_container']['myId_x'] next time I try to assign the same object with the same id self.context['a_container']['myId_x'] ≈ an_object The application stalls without any error message. It requires a restart. I apologies for the vague description of the error, but has anyone experienced anything similar?

What is the context of this error ? A custom application ? A basic grok app ?

A custom CMS app. I am trying to track it down, but I was hoping that
someone might have run into the same mysterious problem. Mvh Sebastian On 23 sep 2009, at 16.05, Souheil CHELFOUH wrote: > What is the context of this error ? A custom application ?

To get more help you should definitely try to cut this problem down to a small test case. Do you have any event handlers that get triggered by adding or removing an object?

Thanks. I have rewritten the code five times in different ways and now
it works. I am not sure I will be able to isolate the problem eventhough it was fairly consistent... however when dropping into the debugger the code never failed so I am guessing some kind of event deadlock. Possibly related to indexing, but this is a just a guess. I was doing stuff in grok.Annotation and in ordinary grok.Containers in the same operation. Whereas I guess this shouldn't be a problem, it seemed to be the only obvious circumstance. Anyway, if someone else runs into a similar problem. Try implementing without annotations. That was the route that solved my problem. That said. I never got to the bottom of the problem and now that I have got it working I have lost too much time to investigate further.
