Sure. At the spanish list someone has a private (his costumer don't want 
to share it) PropertyManagerWithTALES

In this class the properties are TALES expressions

I need something like it

I put the TALES expression in the Property Sheet tab but the data 
retrieved is the execution of the TALES expression

Any idea?
