After applying security patch APSB11-14 on 8.01 we are now seeing this error on every page that makes use of cfwindow. This is what the log file says: CFContainerID: Invalid input. Please conform to regex ^[\p{Alnum}_\-\.:]+$ with a maximum length of 100
UPDATE: We found that the container name can't have a space. That stopped the error.
This is what is in our cfwindow tag:
<cfwindow
center="true"
closable="true"
draggable="true"
height="300"
initShow="true"
modal="false"
name="Unavailable item"
resizable="false"
title="This item is no longer available"
width="500"> text </cfwindow>
