checkbox : unchecked elements not in list
I have following form
<s:form action="updateAccount">
<s:iterator value="accounts">
<s:property name="account"/>
<s:checkbox name="accountStatus" value=={active}/>
.....
</s:iterator>
</s:form>
In my action class I have following
public UpdateAccount account
{
List accountStatus;//list to hold all the checkbox values
List accounts; //list to hold all the accounts values
// getter setters
public String execute()
{
//iterate through the list of accounts/
//set account status value to that list accountStatus
}
}
Ideally I would want the accountStatus list to contains a list of "true" or
"false" strings, however accountStatus list only seems to contains only the
checked
elements...

The use "accounts" in s:iterator is wrong. It probably works if you can create something like "new int [7]".

Unchecked checkboxes in html forms don't submit a value. If you want true
vs. false submitted back to the Java action, you'll need to use radio
buttons.

It looks like you are processing the submitted params
yourself. If that is the case, the browser only gives
you values for the checked boxes. That is an http limitation,
not struts. If you want to do it that way, you will have
to check for the non-presence of unchecked boxes.
Struts will handle the checkboxes correctly if you let it handle
the form submission. On my form bean, I have boolean values
for each of the checkboxes and set the checkbox to use
the field name: <s:checkbox name="myName">
When the user submits the form, everything
works as expected.
Can you do that in your app instead of processing the
request params yourself?
