ByteString>>projectSpec

Hi!

I got this error time to time:

Error creating project: MessageNotUnderstood: ByteString>>projectSpec to reproduce evalutate the following: 'ConfigurationOfSpy project' { projectCreationError } [ #validateProject ]

Apparently something get screwed. Any idea where this could come from?

Did you try executing:

   ConfigurationOfSpy project

This looks like an error that is occurring during validation...

Yes, I found the problem. It was that a version number was missing (i.e., not inserted by the toolbox)
I have no idea why this occurs.

NB: just a remark, you often reply emails with your name in copy. It does not make your email to appear twice ? (what about this email?)

As for empty strings from the toolbox. Those will happen when the
package/project that is listed wasn't found to be installed in the image
(mcz file missing or currentVersion of a project resolves to nil) ... I
chose to throw in an invalid version that would break later, rather than
complain at code generation time ... perhaps I should throw an error
during generation?

I only get one copy of the mail .. so my mail client is allowing me to
get away with this:)

Here is a simple scenario:
1 - Load squeaksource.com/Spy
2 - Add a version using the toolbox (or +Version). I get a DNU ByteString>>projectSpec
3 - When I manually inspect the method, I can see the problem:
        ConfigurationOfSpy>>version122: spec
                <version: '1.22' imports: #('default' )>
                ...
                spec
                        project: 'MemoryMonitor' ;
                        project: 'Merlin' with: '1.0';
                        project: 'Mondrian' with: '2.54';
                        project: 'HealthReportProducer' with: '1.3'.
                ...
4 - The baseline contains:
                ...
                spec project: 'MemoryMonitor' with: [
                                spec
                                        className: 'ConfigurationOfMemoryMonitor';
                                        loads: #('default' );
                                        file: 'ConfigurationOfMemoryMonitor';
                                        repository: 'http://www.squeaksource.com/MemoryMonitor' 
                        ].
                ...
5 - "ConfigurationOfMemoryMonitor project currentVersion" gives me " 1.0.3 [ConfigurationOfMemoryMonitor]"

Complaining at generation time would be a good step I think. I think it is better to not generate a version than generating one that screw up the whole configuration (I could not do "ConfigurationOfSpy project" anymore).

Great. I've created an Issue for this Issue 115<http://code.google.com/p/metacello/issues/detail?id=115>...the toolbox needs more bullet proofing...
