In the solution I posted on the list, only TRCanvas holds the session and if
it changes all attached Shapes resets its path.

Thanks Vincent!
It seems to work well.

Included in Roassal!

Solved !

You will found the changes in the attached .mcz.

I added some sessions guards where some Athens external objects are used.  Stef you were right ;)
Particularly for checking the IV TRCanvas>>canvas and on TRShape>>path that relies on Athens external objects.

It seems to works for me. If it is the case for you, it we be nice to integrate it quickly to be able to work fine :)

Thanks

Vincent

Alexandre

may be you should try to understand what is a session.
Because this is about 2 lines of code.

When you open an image you save 2 min ago or 2 years ago, how the system knows that an OS ressources is valid?
By checking the session id...

Yes, and this is a mess.
I've spent quite some time in getting the session working with Roassal2 and it still does not work. I would appreciate help on this.

It looks like Trachel does not recreate athens external resources.
There is an example in AthensSceneView, on how to check and reload an
AthensSurface.

It is only intended to recover your lost work in the image not for everyday use :).

This may be related to this known issue reported a few days back.

https://code.google.com/p/moose-technology/issues/detail?id=1084



And there is a possible solution to recover your image.

Hi,



Yesterday, I was using GraphET (a part of Roassal) to do some charts and, today, when I wanted to reopen the image.

And I got that :

<image001.png>

It is *very* unpleasant...



To reproduce the bug:

1 - You can do either:

                                | builder |

                                builder := GET2Line data: (0 to: 100) .

                                builder

                                                y: [ :x | x*x ].



                                builder open.

Or

WorldMenu -> Roassal examples -> choose an item -> click on a graph . A TRMorph should be opened.

2 - don't close the graph and save the pharo image.

3 - Close the pharo image

4 - Reopen it



I am under W7 x64 with the latest moose image and the VM available on the pharo.org website (http://files.pharo.org/platform/Pharo3.0-win.zip) from the 10 july.

You will find the crash dump attached.





Thankfully, I managed to open the image with a latest VM (http://www.mirandabanda.org/files/Cog/VM/VM.r3056/cogwin-14.29.3056.zip).

Thanks a lot Eliot ! :)



And I got this:

Thanks in advance
