Magma and UUID?

[Jerry Bell]

Hi,

One of my models has a UUID stored in an instance variable.

It appears that the UUID is not always converted back to a real  
object.   I'm using Seaside, and I often get walkbacks when dealing  
with this ivar.  Specifically, I use this UUID to create a filename,  
using "(myUUID printString), '.rss'."  The walkback shows that I am  
ending up with something like "a MagmaMutatingProxy .rss".  When I  
examine the debugger, I find a MagmaMutatingProxy where I would expect  
to find my UUID.

If I open an explorer on the object, and click on the  
MagmaMutatingProxy, I will see the real UUID appear.  After that  
happens, my application will run with no further problems (I am using  
Magma seasideHelper and I suspect that the reified object is cached).

If I replace my accessor method "^ uuid" with "^ uuid copy" everything  
seems to work correctly.   So far that seems like a good workaround  
but I'd like to make sure I'm not doing something wrong.  Is it  
possible that Magma is not always handling UUIDs correctly?

Thanks,

Jerry
