By map, do you mean ActionMapping? I included the page attribute in validation.xml does it need to go somewhere in struts-config.xml as well ?
<field property="theCard" depends="required,creditCard" page="1" >
<msg key="use.cc" name="required"/>
</field>Is this wrong ? Thanks. Vincent

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

Subject: DyanActionValidatorForm clarification please
Hello All, I am trying to get a multi page validation working right. 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.
