I don't know how it happened (even though I checked it yesterday many times) but I added the new property to the class in a different classlib. Both classlib and classes have the same names so it was easily confusing. But I remember when I decided to go this route (having 2 classlib of the same name) our friend SB warned me that it was a bad practice. And he was right.

Thank you for your help.
