RE: Lost form data after form.validate() and issuing error messages
In the input of second mapping try this /showy.do. Because after
validate, you have to populate the form values again
Let me know this works

Subject: Lost form data after form.validate() and issuing error messages
Hello,
I lose all form data if validate returns error for the form input. If
action goes through validation without creating of any errors,
XAction works fine.
ShowXAction is used to display jsp and jsp posts to XAction. Any
comments? You can see the code below.
cheers,
tuna

ShowXAction.java looks like follows:
public final class ShowXAction extends Action {
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception{
// Update form data
if (form == null) {
form = new XForm();
if ("request".equals(mapping.getScope()))
request.setAttribute(mapping.getAttribute(), form);
else
session.setAttribute(mapping.getAttribute(), form);
}
XForm f = (XForm)form;
f.setA("...");
f.setB("...");
//ensure, that form is submited only once
saveToken(request);
return mapping.findForward("success");
}
XAction.java looks like:
public final class XAction extends Action {
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
XForm f = (XForm)form;
XBean b = new XBean(f.getA(), f.getB());
b.store();
//ensure, that form is submited only once
saveToken(request);
return mapping.findForward("success");
}
and struts-config.xml is like follows:
and finally XForm is like follows:
public final class XForm extends ActionForm {
private String a = null;
private String b = null;
public String getA() {
return this.a;
}
public void setA(String a) {
this.a = a;
}
public String getB() {
return this.b;
}
public void setB(String b) {
this.b = b;
}
public void reset(ActionMapping mapping, HttpServletRequest request)
{
this.a = null;
this.b = null;
}
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {
ActionErrors errors = new ActionErrors();
if ((this.a == null) || (this.a.trim().length() == 0)) {
errors.add(ActionErrors.GLOBAL_ERROR, new
ActionError("form.a.missing"));
}
if ((this.b == null) || (this.b.trim().length() == 0)) {
errors.add(ActionErrors.GLOBAL_ERROR, new
ActionError("form.b.missing"));
}
return errors;
}
public String toString() {
StringBuffer sb = new StringBuffer("XForm[");
sb.append("a=").append(this.a);
sb.append(",b=").append(this.b);
return sb.toString();
}
}

RE: Validate method going in infinite Loop
Thanks Nagendra But on the JSP page I want to show both the errors as well as the data ( form bean variable which are populated in the performAction() method of action class. ) i.e. in validate method if email address is invalid then I am adding the errors and forwarding to JSP page, this page will show the errors only but not the formbean values as it has not gone into the performAction(). So I need to show the errors also and the data also from database. This data is not used for validating the email address but it is used for showing some suggested email addresses.
