Summary	06330: Regex engine does not accept a leading zero even if explicitly specified as acceptable
Description	Regex validation fails when a text input is validated against an expression with a leading zero (e.g. the "Australian postcodes" regex - /^[0-9]{4}/ in the official documentation - would fail if the response starts with a zero).
Steps To Reproduce	1.) Define a free text entry question 2.) Limit max length to 4 characters 3.) Apply /^[0-9]{4}/ as validation expression 4.) Test the question in a submittable survey, and enter any number with a leading zero as answer The answer would not validate.
Additional Information	I have also noticed, that not limiting the answer length to the number of characters implied by the regex, after surpassing this implied limit, the regex would match (resulting in an illegal answer). E.g. typing anything as a 5th digit would satisfy the regex.
Tags	No tags attached.

LimeSurvey: master e60f4f74 2012-07-18 08:52 TMSWhite Details Diff	Fixed issue 06330: Regex engine does not accept a leading zero even if explicitly specified as acceptable Dev core problem was that LEMval() was casting [0-9]+ to a number, so would strip off leading zeros. Now, if has leading zeros, they will be kept.	Affected Issues 06330
