Is is not that easy :)
TRMorph already checks for a new session.
TRCanvas not, but could be done the same way - maybe. It is difficult as
TRCanvas are shared by different objects.
And it is more difficult for TRShape.
I know Igors argument against a session management in Athens for
recreating cairo resources on image start up. It is not the job of Athens.
But it is a bit different for resources created through Athens core api.
How can the user (TRShape for example) know, that a path created by
an Athens surface referes to an external resource?
The attached changeset implements a simple check for TRCanvas and
resets paths if the canvas changes. This solves the crash on
image start up.But it is not a good solution.

The recipe is simple: isolate the code in your
application in a way that
if certain feature not available (line nativeboost), it won't put your
image into endless exception throwing loop.
That's another story. The projects I have seen, using athens, do this with
an explicit use
on AthensCairoSurface. Is there already a way to instantiate an
AthensSurface depending on the
available libraries? And AthensBalloon and AthensCairo don't differ only in
rendering quality, so there
is no real fallback option.

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.

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

Yes it is. But I will not do
TRMorph allInstances do: #delete

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.

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
