Hi.
I have some errors while validating my form.

<package name="view" extends="struts-portlet-default"
namespace="/view">
|
| <action name="AddClientRequestAction_*" method="{1}"
class="autopay.portlet.action.AddClientRequestAction">
| <result
name="input">/WEB-INF/jsp/view/addRequest.jsp</result>

name="source">/WEB-INF/jsp/view/addRequest.jsp</result>

AddClientRequestAction
public class AddClientRequestAction extends ActionSupport {
| private String a = "aaaaaaaaaaaaa";
|
| @Override
| public String execute() throws Exception {
| System.out.println("a: " + a);
|
|
| if (isInvalid(a)) return INPUT;
| addActionMessage("my action message");
| return SUCCESS;
| }
|
| public String getA() {
| return a;
| }
|
| public void setA(String a) {
| this.a = a;
| }
|
| public void validate() {
| System.out.println("AddClientRequestAction - VALIDATE!!!");

Extract from line 422 of MessageFormat.java as it is in Java 1.6.0_07:
for (int i = 0; i < pattern.length(); ++i) {
It seems that, struts 2 validator can't find message patterns. But i tried a great
numbers of message mapping, and with out localized messages only
addErrorMessage("error") method.
Could anyone help me with this error?
Thanks.
