When you configure a ZCatalog index, you can use the name
of a parameterless method. This method is then called during
indexing to obtain the base value used to index.

The method must not be a DTML method!
The indexing process calls the method without parameters
and DTML methods lose all their context in this case.

Apparently, you use a DTML method in this way.
It can no longer access "description", as it lost all
context information.
