New issue 1019 by [hidden email]: Roassal shows an error (red  
rectangle) when image reopned
http://code.google.com/p/moose-technology/issues/detail?id=1019

Roassal gives an error (the red rectangle) problem when an image is saved  
and reopened.

Steps to reproduce:
Do: ROMondrianExample new lines (or open any other Roassal visualization)
save image
quit image
reopen image
You should see a red rectangle in the Roassal window instead of the drawing.

You are using Athens right? There is something to do with Session. When I  
will be in Lille I will see this with Igor.

That is indeed a well-known issue Igor commented on in the pharo dev  
mailing list. The connection to the Athens canvas is broken when closing,  
and can't reconnect.

Indeed, this is an annoying issue.

I did not to see the discussion on pharo dev. What is the outcome?

@Alex, yes I am using Athens that is the default surface for rendering with  
Roassal now in Moose.
In that case, would not it be good to revert default canvas to Morphic  
until the bug is fixed? Because it should impact GraphET as well.

Reverting to the Morphic platform would not be the best. Can you seat down  
with Igor? Maybe this is just a couple of lines of code to add. I know that  
a session has to be created. I am unfortunately very very busy until the  
next two weeks

Ok, I'll try to have a look at that with Igor.

Alex, can you try the patch attached here. It should normally solve the  
problem. I added session management in ROAthensMorph as discussed on Pharo  
list. I tested on Moose 5.0.

small correction because removing unnecessary code for surface  
initialization.
