[xwiki-users] Static list value vs. display

Hello all, I'm not sure if I'm doing something wrong or not, but I have an issue with my static lists. I set the "value" as follows: 1-choice 1|2-choice 2|3-choice 3 when I view my form I see the choices as follows: choice 1 choice 2 choice 3 which is what I expect, however...if I change the value before the dash or remove the selection all together from the class all items which have that selection get the "hidden" value. For instance, if a page was created using "choice 1", and the selection of "choice 1" exists in the class, then viewing the page will indeed show "choice 1". However, if I remove "choice 1" or change it to "selection 1" for instance, then all instances previously using that selection will then display "1". is there any way to prevent previously created pages from changes when the class changes?
