Use the lazyValidatorActionForm, which allows you to keep things request scope when using arrays.
http://www.niallp.pwp.blueyonder.co.uk/ <form-bean name="SampleMain" type="org.apache.struts.validator.DynaValidatorForm"> <form-property name="subForm1" type="java.util.ArrayList"/> <form-property name="subForm2" type="java.util.ArrayList"/> </form-bean> Unfortunately I haven't tried this, but am pretty sure it works. sandeep -----Original Message----- From: Nathan Ewing [mailto:[EMAIL PROTECTED] Sent: Tuesday, April 20, 2004 5:49 PM To: [EMAIL PROTECTED] Subject: Creating an indexed property of DynaActionForms I'm trying to figure out how to define and use a DynaActionForm which has an indexed property that is another DynaActionForm. I'm using struts 1.1. Here is something like what I mean: First my sample struts-config.xml ---------------------------------- <form-bean name="SubForm" type="org.apache.struts.validator.DynaValidatorForm"> <form-property name="property1" type="java.lang.String"/> <form-property name="property2" type="java.lang.String"/> </form-bean> <form-bean name="SampleMain" type="org.apache.struts.validator.DynaValidatorForm"> <form-property name="subForm1" type="SubForm[]"/> <form-property name="subForm2" type="SubForm[]"/> </form-bean> And the JSP: ------------------ <table> <c:forEach var="subForm1" items="${SampleMain.map.subForm1}" varStatus="status"> <tr> <td><html:text property="subForm1[${status.index}].property1" size="5" /> <td><html:text property="subForm1[${status.index}].property2" size="5" /> </tr> </c:forEach> </table> Unfortunately this doesn't work. If I try making the subtypes SubForm[] like above, I get a NullPointer exception when I try to start the server, when struts tries to create the DynaForm classes. If I make the property type Object[], I can successfully populate the form, but when I try to save it, I get an ArrayOutOfBounds error when struts tries to create the initial DynaForms (Obviously because it has no idea what type of form to create, I think). How do I make this work? Also, once I start implementing validation on this form, is it going to be possible to use struts validation to validate the subitems?
