I have a jsp containing an indexed test box field, and I need to validate the
user enter a value into all the text boxes when clicking on the save button.
Validation is done OK, but there is an issue. Let me give you an example
illustrating the issue: if there are three text boxes, the user enters 1, 2
into the first two boxes, but didn't enter anything in the third box, struts
validation catch and display the correct validation error on the jsp saying
he/she needs to enter values for all the text boxes, then it wipes out 1 and 2,
which is not what I wanted. What I wanted was that when displaying the
validation error, it should keep 1 and 2 which was entered by the user. Any
suggestions? I appreciate your helps!
Here are my classes:
public class TestingForm extends ValidatorActionForm {
private LabelValueBean[] listOfItems ;
public LabelValueBean[] getListOfItems() {
return listOfItems;
}
public void setListOfItems(LabelValueBean[] beans) {
listOfItems = beans;
}
}
public class DisplayAction extends org.apache.struts.action.Action {
public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws NestedException {
TestingForm testingForm = (TestingForm) form;
LabelValueBean[] listOfItems = new LabelValueBean[3];
LabelValueBean bean1 = new LabelValueBean("1", "");
LabelValueBean bean2 = new LabelValueBean("2", "");
LabelValueBean bean3 = new LabelValueBean("3", "");
listOfItems[0]=bean1;
listOfItems[1]=bean2;
listOfItems[2]=bean3;
testingForm.setListOfItems(listOfItems);
return mapping.findForward("myJsp.jsp");
}
}
myJsp.jsp
<html:form action="/testingSaveAction" method="post">
logic:iterate name="testingForm" property="listOfItems" id="labelValue">
Indexed field to be validated: <html:text name="labelValue" property="value"
indexed="true"/><br />
/logic:iterate>
<html:submit property="submit">Save</html:submit>
</html:form>
In validaton.xml I set up the validation for the indexed filed:
<formset>
<form name="/testingSaveAction">
<field property="value" indexedListProperty="listOfItems"
depends="required">
<msg name="required" key="thisfield.cannotblank"/>
</field>
</form>
</formset>
