Regular Expression for classic UI

[GauravKumar]

I am using /^[.?\d]+$/ expression for validate the version. When I am using this expression in touch UI it's working fine, I am able to enter the value in this format (1.2.2). But, When I am using same Expression in classic UI it's not working. For classic UI, I have used regex Property and custom listener also. But this expression is not working and I have used any other expression but all other also not working in classic UI. Only for Alphabetic and numeric is working in classic UI.

So can anyone help me on this.
