Re: need help about ODMG, urgent

It is entierly possible that the ODMG code generated by the refactored OPP is 
not correct. This is so because there were no working samples or tests of the 
ODMG stuff at the time of the restructure.

I have the ODMG spec. and could dive into this but there are at least 10 other 
things that have higher priority for me first. Anyway, one area which is not 
supported is the query language (OQL). I know this has been discussed a 
couple of years ago so do a search in the mail archive.

link(), setLink() etc are methods that should occur in the generated proxy. 
Sounds like these methods are indeed not needed in the Object...

I hope that someone else chimes in that are more familiar with the ODMG 
stuff...
