can't add url alias for custom class

Sunday 08 November 2009 8:18:51 pm

For some reason I can't add url aliases for objects of a custom class. Articles work fine, and if I add a new custom class to the same site it also works. It fails silently when I try to add the url alias from e.g. http://admin.example.com/content/urlalias/503

I'm concerned this may be one of those deep hard-to-spot bugs like I've tripped over with ez before. The site (and the class) have gone through upgrades of many versions of ez... from around 2005 to (currently) ez 4.0.7.

Has anyone seen behaviour like this, or can suggest where/how to debug this?

I would post a bug report, but I can't replicate it other than with the class in question - quite frustrating.

Thanks
Matthew
