RE: help me about indexed properties

Thank you Craig

now I have a form

TestBeanForm.java
public class TestBeanForm extends ActionForm {
   public ArrayList getTestBean() {
       if(testBean==null)
         testBean=new ArrayList();
       return testBean;
   }

   public void setTestBean(ArrayList testBean) {
       this.testBean = testBean;
   }

private ArrayList testBean;

}

and I write in the jsp this:
<html:form action="/testAction.do">
<logic:iterate name="testBean" id="mybean1" indexId="0">
<html:text name="testBean" property="" value="0" />
(QUESTION: I DONT KNOW WHAT TO SET TO THIS PROPERTY NOW, YET IT IS A MUST HAVE ATTRIBUTE) 

  </logic:iterate>
  <html:submit property="submitValue">Submit Changes</html:submit>
</html:form>


and this is what I have in my configuration file

       <action path="/testAction"
           type="com.viador.rv.action.TestAction"
           name="TestBeanForm"
           scope="session">
       </action>

what should I do to submit values for my ArrayList type object testBean?


well, I suddenly found that testBean is not a bean, so those I have in the jsp file is meaningless, but then how can I submit values for an ArrayList object?

Thanks&Regards

Hi Mike, the attributes for logic iterate are all explained here:
http://jakarta.apache.org/struts/userGuide/struts-logic.html#iterate
and
http://jakarta.apache.org/struts/faqs/indexedprops.html

I've put it in my own words for you below:

For logic:iterate
==================
name attribute: tag looks in all three scopes
(page,request,application)for a bean with the name
equal to the value of this attribute. If it is found, and there is no
"property" attribute
specified elsewhere in the tag, then it will use the bean from the name
attribute as the List/Map to
iterate over.

property attribute: The property specified in the property attribute will
be applied against the
bean found in the name attribute and the value of this property will be
used as the List/Map to
iterate. So if you specify name="MyForm" and property="addresses" then
the list which will be
iterated over will be the value passed back from the interate tag
evaluating MyForm.getAddresses()

id attribute: for each loop of the iterate tag, place the next element
from the list into a
page-level bean named by the value of the id attribute.

idIndex attribute: for each loop of the iterate tag, place the current
index value of the element
from our List in the page-level int variable named by the value of the
idIndex attribute (value is
in [0..list.length])

For html:text
===============
The attributes are pretty well explained in
http://jakarta.apache.org/struts/userGuide/struts-html.html#text

Hope that's enough to get you started.
