Accessing indexed properties in DynaActionForm (1.1rc2)
Hi!
I found no answer in an archives, so I'm asking now.
I've got an indexed property "phone", which has fields "num" and
"pid"(phone ID)
the generated HTML is:
----------------------------------------------------
<tr><td>
<input type="hidden" name="phone[1].pid" value="528078">
<input type="text" name="phone[1].num" value="9795036"> (8)
</td></tr>
<tr><td>
<input type="hidden" name="phone[2].pid" value="528738">
<input type="text" name="phone[2].num" value="9563743"> (8)
</td></tr>
----------------------------------------------------
The DynaActionForm bean in struts-config.xml:
----------------------------------------------------
<form-bean name="EditRecordForm"
type="org.apache.struts.action.DynaActionForm">
<form-property name="cid" type="java.lang.String"/>
<form-property name="name" type="java.lang.String"/>
<form-property name="phone" type="Phone[]"/>
</form-bean>
----------------------------------------------------
The "Phone" class has 2 java.lang.String private members (num, pid) with
public get/set methods.
So, when I'm trying to call the Action's execute method, I got the
following exception occurs:

By default the phone is null. However if you initialize it, and the form
is in session scope
everything should work.
If the form is in request scope make sure that the phone array is
initialized to the right size.

No, Steve. This Exception is generated BEFORE the execute method call,
as you can see in a stacktrace. Struts can't PARSE the parameters.
