[opencms-dev] CRE: is this a bug?

[Marc Schlegel]

Hi

I am still trying to find some documentation about this CRE. For exmaple
I was playing around a little bit. I removod the relation, so I just had 
a OpenCmsVfsFile, then I tried to delete a resource and the dialog 
showed me a weak xml-link (with the relation it showed me a strong 
link). But where is the difference? What do I gain when I use a strong 
realtion for resources.

Any comments apreciated

Thanks
