Problem with validateRegExp (problem with IE and chrome but works for firefox)

Question

Hi everyone,
I have a simple af:inputText with an af:validateRegExp in it with pattern "([^$%# ]+([ ]*[^$%# ]+)*)$".
Now when I enter a very big value in this inputText and finally add a space to it, it gives a proper validation exception in Mozilla FireFox.
But when I run the same thing in IE/ Chrome the screen hangs and after some time page not responding exception comes. What it is observed in chrome is that after a very long time it gives the proper validation exception even if page not responding error has come earlier. Has anyone faced such kind of problem earlier? Is there any solution for this?
{code}
<af:inputText label="Label 1"
                      binding="#{backingBeanScope.backing_datePOC.it1}"
                      id="it1" maximumLength="120">
          <af:validateRegExp pattern="([^$%# ]+([ ]*[^$%# ]+)*)$"/>
        </af:inputText>
{code}

Hi Frank,
Thanks for your reply. I tried checking this pattern in java as well using an validator, in that case the thread got sucked for a bigger length string. So I guess the problem is with expression only. But I dont get one thing, if the problem would have been with expression it shouldnt have worked for smaller length string. But in this case it is working fine with a smaller length string.
