Hi Sheldon,
Thanks again for the reply.

I guess I'm trying to update the VO.

This is what I'm trying to do:
it's a a maintenance page with many detail lines, each of these lines has zero,one or many milestones associated with it.


I read the details from the DB and create a bean with a list of all the detail lines. Within ech detail line there is another list with the milestones. I retrieve and display the data OK. The problem comes when I try to get the updated information from the page.

What exactly does the code listMilestone[1].status in the html mean? I see that you say I need a getListMilestone method, but what about the setter? How does the .status part work.

Sorry i'm being a bit vague here, but I'm reallyt confused!!

Hi Sheldon,

Thanks for the reply. I tried what you suggested, but to no avail...

this is what I put in the form:

private List designMilestoneList = null; ........ public DesignMilestoneVO getListMilestone(int index) { return (DesignMilestoneVO) designMilestoneList.get(index); } public void setDesignMilestoneList(List designMilestoneList) { this.designMilestoneList = designMilestoneList; }

I still get the same error message.

I'm trying to using the html:radio tag with the indexed property. I am able to display the radio buttons as I wish, but am confused as to how I should set up the form to receive the values.
This is how I've coded the JSP:

<logic:iterate id="listMilestone" name="designVO" property="designMilestoneList" indexId="index" type="au.com.xxxx.VO.DesignMilestoneVO"> <html:radio name="listMilestone" property="status" value="red" indexed="true" /> <html:radio name="listMilestone" property="status" value="yellow" indexed="true"/> <html:radio name="listMilestone" property="status" value="green" indexed="true" /> </logic:iterate>

which results in the generated html:
<input type="radio" name="listMilestone[0].status" value="red"> <input type="radio" name="listMilestone[0].status" value="yellow" checked="checked"> <input type="radio" name="listMilestone[0].status" value="green"> <input type="radio" name="listMilestone[1].status" value="red" checked="checked"> <input type="radio" name="listMilestone[1].status" value="yellow"> <input type="radio" name="listMilestone[1].status" value="green">
So what should I have in the associated form?

If I leave a variable with the name listMilestone out of the form completly, the I don't get any errors, but I also don't get the value
of the radio button submitted.

If however, I have a String variable listMilestone, the I get errrors like:
java.lang.NullPointerException org.apache.commons.beanutils.PropertyUtils.getIndexedProperty(PropertyUtils.java:515) org.apache.commons.beanutils.PropertyUtils.getIndexedProperty(PropertyUtils.java:428) org.apache.commons.beanutils.PropertyUtils.getNestedProperty(PropertyUtils.java:770) org.apache.commons.beanutils.PropertyUtils.getProperty(PropertyUtils.java:801) org.apache.commons.beanutils.BeanUtils.setProperty(BeanUtils.java:881) org.apache.commons.beanutils.BeanUtils.populate(BeanUtils.java:808) org.apache.struts.util.RequestUtils.populate(RequestUtils.java:1252) org.apache.struts.action.RequestProcessor.processPopulate(RequestProcessor.java:821) org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:254) org.apache.struts.action.ActionServlet.process(ActionServlet.java:1482) org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:525) javax.servlet.http.HttpServlet.service(HttpServlet.java:709) javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
The request has a paramter name "listMilestone[1].status", so how do I cater
for that in the form???

How should I declare the variable, and what should the getter and setters look like?


I'm really pulling my hair out with this one!!!
