Well the lazy beans themselves look easy to work with, but I have to write code that converts the lazy beans to regular dynabeans (and back). My normal dynabeans have extra fields in them to do things like specify the correct table to save a bean to, and also formatting options for beans going to and from the database (for example to convert Date fields correctly from a user viewable to database workable form going in and out automatically).

I got half way to implementing the approach, but the piece I was building was shut down so I don't know how effective it is. sandeep -----Original Message----- From: Nathan Ewing [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 21, 2004 1:48 PM To: Struts Users Mailing List Subject: RE: Creating an indexed property of DynaActionForms I briefly toyed with the idea of trying to fix the flaw myself, but I looked at the struts source code and the change would not be a trivial one. -----Original Message----- From: Takhar, Sandeep [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 21, 2004 1:33 PM To: Struts Users Mailing List Subject: RE: Creating an indexed property of DynaActionForms I couldn't think of one. sandeep -----Original Message----- From: Nathan Ewing [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 21, 2004 11:00 AM To: Struts Users Mailing List Subject: RE: Creating an indexed property of DynaActionForms I take it then that there is no way to use normal DynaActionForms. It would certainly be a lot simpler. :( Nathan -----Original Message----- From: Takhar, Sandeep [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 21, 2004 7:44 AM To: Struts Users Mailing List Subject: RE: Creating an indexed property of DynaActionForms 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?
