[Helma-user] _extends & _prototype

[Jonathan Puckey]

Ack.. This isn't working in the way I wanted it to after all..
When I restart my app and point to /Exhibitions/archive/2005/this-is- 
the-title/, it uses the Page prototype and not the ArchivePage  
prototype..
And then sometimes it does use the right one.. Flakey at best!

So I need a different approach, I guess..
What would be the best way to have the main.hac that is fired be  
dependent on the collection that it resides in?

Thanks,
Jonathan
