Please, does someone have a response ? My field "name" is made like that : - Validation Regular Expression : /.{1,15}/ - Validation Message : ApplicationClass_nameValueError And I have a translations page (that is weel defined in my "Wiki Administration Page") and said : Space.ApplicationClass_nameValueError=Your name is too long As I said before, when I don't want an empty field, I use /.+/ and a Validation Message and there is no problem. Is the expression /.{1,15}/ a deprecated expression or is there a problem somewhere ?? Thanks for your response.
