[richfaces-issues] [JBoss JIRA] (RF-11531) Client side validation: regexp ignores whitespace at the beginning

[Brian Leathem (Commented) (JIRA)]

    [ https://issues.jboss.org/browse/RF-11531?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12635880#comment-12635880 ] 

Brian Leathem commented on RF-11531:
------------------------------------

The javascript regexp interpretation is actually correct.  It checks for the pattern matched within the input value, not starting with.

If you want it to start with, change the pattern to "^[a-z].*"

> Let "[a-z].*" is expected regexp and input value is " a". The value shouldn't pass the validation, but it passes.
