Validator mask boundary matchers don't work
I'm using Struts 1.1. I have an html:text input field.
I'm trying to constrain the input field to be two strings separated by
a space.
I have tried
<var-value>\w\s\w</var-value>
but that allows two *or more* strings separated by spaces, such as "xxx
yyy zzz".
I have tried using the boundary matchers, as in
<var-value>^\w\s\w$</var-value>
Then no input works. I thought I read that ^ and $ are required in
1.1, but I can't get it to work with them.
It's not then expecting literal ^ and $, but I don't know what it's
doing.
TIA.

--> Since version 1.1, the regular expression must start with a ^ and
end with a $ (see example below).

This worked:
^\w+\s\w+$
In other words, the boundary matchers work when I have the right
regexp. :-)

I tried \w+\s\w+ (plus instead of * in order to require at least one),
and it still accepts more than two strings, e.g. "xxx yyy zzz"...

Thanks, I appreciate your reply.
\w\s\w has been working for me for some time with multiple characters
in each word, such as "Leonard Sitongia" (it's a text input for a
person's name). I just recently discovered that it is also working for
"Leonard E Sitongia", which I didn't want. So, I assumed that \w mean
word, not one character.
I'll try your suggestion.

Leonard,
Lets see if I can help, I hope my regex skills aren't totally rusty.
That regualar expression will only match exactly one word character then
one whitespace character
then another word character. (A word character is in the set of a-zA-Z0-9_)
Try using this regex <var-value>^\w*\s\w*$</var-value> hopefully it will
solve your problem.
