HI,
I am not sure if this reached the list the first time round.
I have the following DynaFormBean defined in tiles-def.xml:
<form-bean name="answerDetailsForm"
dynamic="true"
type="org.apache.struts.action.DynaActionForm">
<form-property name="fieldIdMemberIds"
type="java.lang.String[]" />
<form-property name="questionName" type="java.lang.String"
/>
</form-bean>
I am using the following code excerpt from the form which creates the
<%=name%> dynamically
based on values returned from the database.I want to use DynaFormBeans or a
sub-class of it
or DynaValidatorForm to make sure that the field is required and one of the
radio buttons for
each field is checked. How can I do that ?
<%
for (int i1=0;i1 < fields.length; i1++) {
Field field = (Field)fields[i1];
long fieldId = field.getFieldId();
String name = "fieldValue";
String member = "memberId" + memberId;
name = name + fieldId + member;
%>
<tr align="right">
<td><input type="hidden" name="fieldIdMemberIds" value="<%=name %>"
/></td>
<html:errors property="<%=name%>" />
<td><%=field.getFieldName()%> </td>
<%
Collection colFieldValues =
FieldValuesHandler.getFieldValues(fieldId);
Iterator iterFieldValues = colFieldValues.iterator();
while (iterFieldValues.hasNext()) {
FieldValues fieldValue = (FieldValues)
iterFieldValues.next();
%>
<td><input type="radio" name="<%=name%>" value="<%=fieldValueDflt%>"
<%if (fieldValueAnswer.equals(fieldValueDflt)) {%>checked <%}%>
/><%=fieldValueDflt%></td>
<%
}
%>
I have the following code in my action class and call validate(..) method
from the execute() method:
public ActionForward validate(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws
ServletException {
boolean validated = true;
DynaActionForm dynaForm = (DynaActionForm) form;
String[] fieldIDMemberIds = (String[])
dynaForm.get("fieldIdMemberIds");
for (int i = 0; i < fieldIDMemberIds.length; i++) {
String fieldIdMemberId = fieldIDMemberIds[i];
String answer = request.getParameter(fieldIdMemberId);
if (answer == null || answer.length()<= 0) {
ActionErrors errors = new ActionErrors();
ActionError newError = new
ActionError("validate.error.required",fieldIdMemberId);
errors.add(ActionErrors.GLOBAL_ERROR, newError);
saveErrors(request, errors);
// Return back to the previous state
validated = false;
}
}
if (validated) {
return null;
} else {
return mapping.getInputForward();
}
}
Unfortunately, when i try to use <html:errors />, it just prints out the
last error only.
Thanx in advance,
Vijay
