Hello,
What does the getFormData method return?
It should be a bean with exactly the same properties as your
dynavalidatoraction form..

Subject: Re: How do I prefill a form
Here is the entire contents of my init method:
if (form == null) {
form = new DynaValidatorActionForm();
}
CommonTools.formDataCopy(request, form);
return mapping.findForward("searchName");
If I break on the CommonTools line and put my mouse on the form,
I see form is not null, but is empty.
The contents of the formDataCopy method is:
BeanUtils.copyProperties(object, getFormData(request));
The getFormData method retrieves the "formData" bean from the
request. The bean exists and has the previously entered
information.
If I let the request run it's couse, I get an error message:
12:04:26,098 WARN [RequestProcessor] Unhandled Exception
thrown: class java.lang.NullPointerException

com.appriss.jxportal.CommonTools.formDataCopy(CommonTools.java:281)
at
com.appriss.jxportal.search.SearchAction.nameInit(SearchAction.java:47)
CommonTools.java:281 is the BeanUtils.copyProperties line. It
seems like I am not creating the form correctly.
