It works great! Thanks Lukas!

And
descriptionContainer
   ^(super descriptionContainer)
       addCondition:
               [:value |
               (value cache at: self descriptionStartDate)
                   < (value cache at: self descriptionEndDate)]
           labelled: 'Start date must be before end date';
       yourself

Worked great Ramon!

But how can i validate the unicity of an object in a collection but
inside a description? is this possible? the idea is to keep the
validation inside the description throw addContition:labelled:

Thanks again :)
