Field Validator that checks if the date supplied is within a specific range.
NOTE: If no date converter is specified, XWorkBasicConverter will kick in to do the date conversion, which by default using the
Date.SHORT
format using the a problematically specified locale else falling back to the system default locale.
- fieldName - The field name this validator is validating. Required if using Plain-Validator Syntax otherwise not required
- min - the min date range. If not specified will not be checked.
- max - the max date range. If not specified will not be checked.
- parse - if set to true, minExpression and maxExpression will be evaluated to find min/max
- minExpression - expression to calculate the minimum value (if none is specified, it will not be checked)
- maxExpression - expression to calculate the maximum value (if none is specified, it will not be checked)
You can either use the min / max value or minExpression / maxExpression (when parse is set to true) - using expression can be slightly slower, see the example below. Do not use ${minExpression} and ${maxExpression} as an expression as this will turn into infinitive loop!
