Hi Dominik, I also use other regex for other text boxes and they have
double-slashes and they work.
For example I have another textbox which validates against this regex:
public static final String REGEX_PINCODE = "[\\w]{12}";
That one has no problem in IE or Firefox.
I tried changing the original problematic regex to this (to avoid
double slash altogether):
^(?=.*[0-9])(?=.*[a-z]).{8,15}$
But the problem still remains for IE. I don't have a lot of insight
into this issue. I just installed the DebugToolbar, and now I will re-
compile it all with readable JavaScript to see if I can spot anything,
but I'm drawing a blank on this one. I'm not much of a javascript
maven. If anyone has any insight, I'd be thrilled to hear it.
Regards,
Davis
