Vincent, Do you have an entry in your map named page? Not having the entry will cause your problem.

Before my page even load I get a 500 error from tomcat 4.1.29: java.lang.NullPointerException at org.apache.struts.validator.DynaValidatorActionForm.validate(DynaValidatorAc tionForm.java:115) I am using struts release 1.1. I checked the source code and I see the offending lines: public ActionErrors validate(ActionMapping mapping, HttpServletRequest request) { // set the page variable before validating Map props = this.getMap(); if (props.containsKey("page")) { ---> this.page = ((Integer) props.get("page")).intValue(); } I'd like a few clarifications about what I have read on the list and on the validator guide: <http://jakarta.apache.org/struts/userGuide/dev_validator.html> Are the following assertions true or false? To use DynaActionValidatorForm you must define a property in your ActionForm called "page" of type java.lang.Integer In your web form you must have a tag with the page value: <html:hidden property="page" value="1" /> On the page you must also have a tag like : <html:javascript formName="/MyAction" method="validatesmyAction" page="1" /> I have tried many permutations of these parameters. I get a NullPointerException whether I have a "page" attribute in "field" element (gotta love the struts naming conventions :) ) in validation.xml or not. The exception only goes away if I set validate to false in struts-config.xml Thanks in advance. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
