Class::Accessor and Storable

Belgarion has asked for the wisdom of the Perl Monks concerning the following question:

Are there any known problems with using Storable with a Class::Accessor derived module? I'm trying to nfreeze a module derived from Class::Accessor and send it across a Unix socket to be thawed by another application. The nfreeze method seems to work fine, and the thaw succeeds without an error; however, when I try to access a method defined in the class's mk_accessors method I receive an error stating that the thawed object doesn't have a method by that name.

Is what I'm trying to do impossible, or should I be looking in a different direction?

Thank you for any help you can provide.

This may be a stupid question, but does the other application actually load ("use") the class (module) the object is blessed in before you thaw the object? I don't think storable does this automatically. Also, the subclass should probably explicitly `use Class::Accessor` or `use base 'Class::Accessor'`, if it doesn't already does so.

Thanks Joost++! I added the `use ModuleName` to the client code and it works correctly now.	[reply]

not sure if this is related, but I did have issues once which, after many hours of frustration, I discovered stemmed from my use of Storable which exports the methods store & retrieve. My module was a subclass of another which used the method store somewhere.. I wasn't even aware of it.. Anyway Storable was overriding the store method and causing some really weird errors. The solution of course was quite simple.. `use Storable();` [download] as opposed to `use Storable;` [download] cheers, J	[reply] [d/l] [select]
