Hi Esteban, thank you for your quick response. I already had the >>enableMissingContent method in the mongoContainer (see fileout).
I was trying with a new Image and it worked! In the old image, I debugged into and the Image froze in >>basicNew in VOLazyProxy>>repository: aRepository objectClass: aClass id: idObject ^self basicNew initializeRepository: aRepository class: aClass id: idObject For now, I take the new image and proceed. But I dont know the reason for freezing and hope it will not come again :-) Thanks again Sabine On Thu, Aug 15, 2013 at 1:34 PM, EstebanLM [via Smalltalk] < ml-node+s1294792n4703743...@n4.nabble.com> wrote: > Hi Sabine, > > yes...
