can you save an image with the inspector opened on both x and y, x asTime and y asTime and provide a link to it? like that I can inspect it in all detail...

I tried it again this morning and still had the problem.

Hi Damien, Because of the attached Message Tally outputs I don't think the problem is specific to changes I've made to an image. I also don't think that there is much differnece between Eliots vm or the pharo ppa vm. The Message Tally outputs are from profiling the UI while finding the senders of #setUp using various VM & image combinations. On squeak finding the senders of #setUp seems instantaneous. On Pharo it takes multiple seconds to find and display the senders. It may be my expectations are different than they should be. Is the result from the pharo ppa vm + pharo 2 image similar to what you're seeing on the 32bit Ubuntu? Thanks for looking into this. For what its worth I'm using a 5 yr old Dell D630 laptop with an 3GB of ram and a 120 GB SSD. I've also attached the output from /proc/cpuinfo Please let me know if there are other things I should check.

Voyage: Circular references

by Bernat Romagosa

Hi! I'm having an issue I don't recall having had about half a year ago when trying out Voyage. In my schema, a *User* has an *instVar* referencing all the *Center*s he belongs to, and a *Center* has an *instVar* referencing all of its *User*s, so when the Voyage serializer tries to serialize a user (or a center), it goes into an infinite loop trying to find the end of the reference chain and the image clogs. I remember saving the exact same schema a while ago without a problem, is there something new I should know about? BTW, I'm using the #bleedingEdge version, with Magritte3 and all. Thanks! :) -- Bernat Romagosa.

I can *not* reproduce your problem with the VM on the PPA. Just to be sure, I sent new versions of the packages to the https://launchpad.net/~pharo/+archive/stable/ PPA this morning.

Thanks. Try it again in the morning! I think it's related to time zones. If, in your local time, it is not yet midnight, but it's already the next day at GMT, then you get a negative "something" (can't remember what). I've seen the '-' (negative integer) show up in the time printString result. I think I fixed it by printing the hours/minutes/seconds with a custom print method.

DateAndTime now asTime inspect -----> 8:58:38.218 pm which is correct. THis is from a virgin image (no package imports) created by unzipping the Windows download. I will try a different DateAndTime instance creation method tomorrow and let you know. This is strange.
