html:multibox reset?

[fea jabi <zy...@hotmail.com>]

I am using html:multibox in my jsp.

I am not sure when the reset method is needed. Not sure if I have to use it. 
I have declared my formbeans in config file itself. If I have to use how to 
use that?

I am having the below code now to display a group of checkboxes in a column 
of a table.

<form-bean>
     <form-property name="Items" type="java.util.ArrayList"/>
        <form-property name="SelectedItems" type="java.util.ArrayList"/>
</form-bean>



In prepare Action
...............
...............

LabelValueBean lblValueBean1 = new LabelValueBean("Visa1", "V1");
LabelValueBean lblValueBean2 = new LabelValueBean("MasterCard1", "M1");


ArrayList misList = new ArrayList();
misList.add(lblValueBean1);
misList.add(lblValueBean2);

ArrayList selectedList = new ArrayList();
selectedList.add(lblValueBean1);

form.set("Items", misList);
form.set("SelectedItems", selectedList);
.....................
.


In JSP
............
..........
<logic:iterate id="item" property="Items">
   <html:multibox property="selectedItems">
         <bean:write name="item" property="value"/>
   </html:multibox>
         <bean:write name="item" property="label"/>
</logic:iterate>


Thanks.

Multibox is just another way of managing checkboxes, so the same caveats 
apply as with any other checkbox backing property: if you want to be 
able to recognize when a checkbox is de-selected, you must arrange for 
the backing property to be set to false before it's populated from the 
request.

Your from bean doesn't have a type declared. That's not going to work, 
since Struts can't know what class to instantiate if you don't tell it.
