Hi Tres,

Yes that was the solution I found ...
But I need to use the size of the portal in a modified UrlTool so it woul=
d=20
need to query the catalog each time a page was loaded (I don't think that=
=20
would be such a good idea *S*).
So - instead of using just an index in the catalog, I subclassed the cata=
log=20
and overruled the indexObject, unindexObject and reindexObject methods. H=
ere=20
I extracted the value of get_size of the object and incremented/decrement=
ed=20
an attribute in the tool that contains the total size of the portal. Not =
the=20
perfect solution but it works :-)

Thanks for the tip!
