Hello,

I want to write about a newbie discover I did about test on "empty" value for advanced mode config tests as:

So the question was :

How to not show a document field in a custom layout if it's empty ?

Because I got I boring test such as :

#{layoutValue.dc.nature==null || layoutValue.dc.nature==''?'hidden':'view'}

The solution is in advanced mode configuration write, as example :

#{empty layoutValue.dc.nature?'hidden':'view'}

with key word "empty"
