The client side Regex validator needs to specify the start and end of the
pattern
---------------------------------------------------------------------------------
Key: TRINIDAD-1181
URL: https://issues.apache.org/jira/browse/TRINIDAD-1181
Project: MyFaces Trinidad
Issue Type: Bug
Environment: Windows XP
Reporter: Anita Anandan
Priority: Minor
The following pattern should match numbers 1-999:
"[1-9]|[1-9][0-9]|[1-9][0-9][0-9]". Granted there are better ways of specifying
the regex for numbers 1-999. Still this pattern should match numbers 1-999. In
reality the client side validation only matches numbers 1-9.
Note that the reverse pattern, i.e. "[1-9][0-9][0-9]|[1-9][0-9]|[1-9]" matches
numbers 1-999. Also note that the server side Java Regex Validator works as
expected, matching both the pattern and the reversed pattern to numbers 1-999.
The reason the 10-999 is not matched by JavaScript to
"[1-9]|[1-9][0-9]|[1-9][0-9][0-9]" is that the first digit always matches. So
it doesn't need to go down the chain. In order to indicate to force it to do
so, we need to ground the start and end, and include the pattern in
parenthesis. i.e. We need the pattern to be
"^([1-9]|[1-9][0-9]|[1-9][0-9][0-9])$".
