Changed the token used to split the id and the text on the list constraint items from " - " to "!".
I've changed this because I was unable to use the Data Dictionary Localization feature based on properties files.
This don't work: listconstraint.sample_areaConstraint.1 - 1=Área A
So I used this: listconstraint.sample_areaConstraint.1!1=Área A

As I'm using properties files to define the items labels, I removed the code in for the view mode
