I don't think using the lazy beans is a bad approach and if you look at the code, there is very little of it.
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?
