Re: [Pharo-users] Beginner's question ...

Hi Roland, Can you be more certain? Is your main goal to interact with a final product because you do not have gui (for example web service). Or you just want to develop some application that can be used only with command line etc... Cheers.

Beginner's question ...

by Roland Strasser

Hi, I have programming experiences with BASIC compilers. I would like to program in a Smalltalk environment; but I have the following newbie's questions: a) Can I deploy an image without all the browsers and other "stuff" - just a plain console program? b) How is it possible to write a console program without gui etc.? Thank you! Roland.

Re: [Pharo-users] Voyage: image freeze/VOMongoError: Lazy reference not found

by Sabine KnÃ¶fel

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+s1294792n4703743h28(a)n4.nabble.com> wrote: > Hi Sabine, > > yes...

Re: [Pharo-users] Voyage: image freeze/VOMongoError: Lazy reference not found

by Esteban Lorenzano

Hi Sabine, yes... I have found that problem time to time too. The way to solve it in mongo is to allow the collection to take dead references as "valid missing content". Of course, this is a dangerous feature, and that's why is not enabled by default. To enable it, you need to add a property to the trip container: Trip class>>mongoContainer <mongoContainer> ^ VOMongoContainer new enableMissingContent; yourself that should solve your problem. I could this "eventual integrity" and is very suspicious... but the only way I found to treat in image what could happen outside it... :) cheers, Esteban On Aug 15, 2013, at 12:04 PM, Sabine KnÃ¶fel <sabine.knoefel(a)gmail.com> wrote: > Hi Esteban, > > sorry but I need your help again. > > I succeeded in re-writing all my code to use voyage and can save all my > model now.
