So how do I catch the opposite of this \bBig2\b as with the following (see below) the only time I don't get a matchError is if I type in "Big2". I want the reverse.
vResult = reservedNamesValidator.validate(); if (vResult.type==ValidationResultEvent.INVALID) return; <mx:RegExpValidator id="reservedNamesValidator" source="{nameOfFileInput}" property="text" expression="\bBig2\b" flags="ig" noMatchError="This is a reseverd name" />
