I'm getting an odd exception:
2004-03-08 11:19:41,405 ERROR [org.apache.commons.validator.Validator] reflection: org.apache.struts.validator.FieldChecks.validateRequired(java.lang.Object, org.apache.commons.validator.ValidatorAction, org.apache.commons.validator.Field, org.apache.struts.action.ActionErrors, javax.servlet.http.HttpServletRequest) java.lang.NoSuchMethodException: org.apache.struts.validator.FieldChecks.validateRequired(java.lang.Object, org.apache.commons.validator.ValidatorAction, org.apache.commons.validator.Field, org.apache.struts.action.ActionErrors, javax.servlet.http.HttpServletRequest) at java.lang.Class.getMethod(Class.java:978) at org.apache.commons.validator.Validator.executeValidationMethod(Validator.java:501) at org.apache.commons.validator.Validator.validateFieldForRule(Validator.java:424) at org.apache.commons.validator.Validator.validateField(Validator.java:669) at org.apache.commons.validator.Validator.validate(Validator.java:745) at org.apache.struts.validator.DynaValidatorForm.validate(DynaValidatorForm.java:150)
The parameter list shown in the NoSuchMethodException appears to match the validator-rules.xml file:
<validator name="required" classname="org.apache.struts.validator.FieldChecks" method="validateRequired" methodParams="java.lang.Object, org.apache.commons.validator.ValidatorAction, org.apache.commons.validator.Field, org.apache.struts.action.ActionMessages, javax.servlet.http.HttpServletRequest" msg="errors.required"/>
apart from the fourth parameter (ActionMessages vs ActionErrors) but this is probably OK since ActionErrors is a subclass of ActionMessages.
This parameter list also matches the javadoc.
NB: This is the Nightly Build binary download !!! I can't recall why - just that I had a bug in the stable build that was fixed in the nightly's. However - I've just changed from the old nightly to 20040306 (20040307 seems to be 163 bytes long) to test - and the same problem with validation occurs.
I think I might have had this and found that changing to ActionMessages did solve it, even though it seems unnecessary. This was one of last week's builds. I don't think that reflection process takes inheritance into account.
