As far as I can see your code looks Ok. >From the code of the tag, this exception is throw when the value object is null. Can your sb.getCheckBoxName return null?
That is all I can think of. -----Original Message----- From: Mattos, John [mailto:[EMAIL PROTECTED]] Sent: Friday, March 22, 2002 12:48 PM To: 'Struts Users Mailing List' Subject: RE [2]: Form Question - Dynamic number of checkboxes - Multibox ? Okay, so now I have the following: <logic:iterate id="sb" type="com.indemand.indab.application.invoice.SuspendsTransaction" collection="<%=suspendsByProd%>"> <TR> <TD> <%=sb.getProductName()%> </TD> <TD> <html:multibox property="assetId" value="<%=sb.getCheckBoxName()%>"/> </TD> </TR> </logic:iterate> and I have an int[] field on my bean called "assetId" and it's telling me "You must specify the value attribute or nested tag content" I thought that's what I was doing when I specified value="<%=sb.getCheckBoxName()%>" in the multiBox. the getcheckboxName, by the way, returns the assetId, so I hope to end upwith an array of these things in the bean John Mattos Sr. Developer and Architect iNDEMAND 345 Hudson St. 16th Floor New York, New York 10014 -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Friday, March 22, 2002 11:42 AM To: [EMAIL PROTECTED] Subject: RE: Form Question - Dynamic number of checkboxes Look at the multibox tag. Add an attribute to your form called product (I think it has to be an a String array) and when you read. It will populate the array with the product selected.

Have to use nightly build or new 1.1 beta. Cheers, Dave "Mattos, John" <[EMAIL PROTECTED]> on 03/22/2002 11:13:16 AM Please respond to "Struts Users Mailing List" <[EMAIL PROTECTED]> To: "'[EMAIL PROTECTED]'" <[EMAIL PROTECTED]> cc: (bcc: David Hay/Lex/Lexmark) Subject: Form Question - Dynamic number of checkboxes Hi there all I'm generating a form that can have dynamic checkboxes depending on information retrieved from my database. I basically retrieve a bunch or rows and for each one, I want to create a checkbox. Than, in the Action class handling the form submission, I plan to loop through the checkboxes, and build an array of those that were selected, and do something to them. The problem is that I am tying to name the checkboxes for the ID of the row... here is a JSP snippet: <logic:iterate id="sb" type="com.indemand.indab.application.invoice.SuspendsTransaction" collection="<%=collectionName%>"> <TR> <TD><%=sb.getProductName()%> </TD> <TD><html:checkbox property="<%=sb.getCheckBoxName()%>" /></TD> </TR> </logic:iterate> <!-- end of snippet --> the getCheckBoxName() comes from the database, and it correcponds to the "Product" in this row, and it's dynamic. Struts complains with the following error message.... No getter method for property 4363 of bean org.apache.struts.taglib.html.BEAN Essentially, I'm trying to create the following <input type="checkbox" name="4363"> and struts can't find get4363() in the bean. No surprise there, I can't create getters for all the possibilities. I just planned to loop through the submitted form fields to get the ids checked. Is there any way that Struts can not care that the setters don't exist? Does this make sense?
