PLEASE IGNORE LAST POST!!!
Sorry, guys - please ignore my ramblings in the last post. Was a mistake on my
part converting everything to arrays.
My iteration DOES work with arrays, as well as collections! As follows:
public final class ParametersForm extends ActionForm
{
// --------------------------------------------------- Instance Variables
/**
* The parameter list
*/
private Parameter[] parameterList;
// ----------------------------------------------------------- Properties
/**
* Return the list of parameters
*/
public Parameter[] getParameterList()
{
return(this.parameterList);
}
/**
* Set the list of parameters
*
* @param parameterList The new list
*/
public void setParameterList(Parameter[] parameterList)
{
this.parameterList = parameterList;
}
/**
* Get a particular parameter from the parameterList, based on index
*
* @param index The index of the parameter to retrieve
*/
public Parameter getParameter(int index)
{
return parameterList[index];
}
}
In parameters.jsp:
....
<logic:iterate id="parameter" name="ParametersForm"
property="parameterList">
<TR>
<TD WIDTH="50%">
bean:write name="parameter" property="key"/>
<bean:write name="parameter" property="desc"/>
</TD>
<TD WIDTH="50%">
<html:text name="parameter" property="value" indexed="true"
onchange="validate(this)"/>
</TD>
</TR>
</logic:iterate>
....
In my SaveParametersAction.java I simply get the paramList from the form and
process them...
public ActionForward perform(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException
{
...
ParametersForm paramForm = (ParametersForm) form;
// Get the parameter list
Parameter[] paramList = paramForm.getParameterList();
...do stuff with paramList
}
So, Frank, not sure what you're doing differently! Maybe you can check the code
above and see if you spot anything?
Cheers, and sorry for the confusion - too little sleep, I think!

Frank,
I have just tried mine with arrays, rather than collections, and does NOT work!
Can anyone explain why? Presume it is something to do with getters/setters, but
would appreciate any insight...
Cheers,
Dave

Frank,
could you do me a favour? Could you try using a collection eg Vector instead of
array in your form bean? you should then have the equivalent of the following
in your form bean:
public final class ParametersForm extends ActionForm
{
// --------------------------------------------------- Instance Variables
/**
* The parameter list
*/
private Vector parameterList = new Vector();
// ----------------------------------------------------------- Properties
/**
* Return the list of parameters
*/
public Vector getParameterList()
{
return(this.parameterList);
}
/**
* Set the list of parameters
*
* @param parameterList The new list
*/
public void setParameterList(Vector parameterList)
{
this.parameterList = parameterList;
}
/**
* Get a particular parameter from the parameterList, based on index
*
* @param index The index of the parameter to retrieve
*/
public Parameter getParameter(int index)
{
return (Parameter)parameterList.elementAt(index);
}
}
Let me know if that changes anything
cheers,
Dave

Hi, Dave:
Thanks for the reply, I did have form-bean define at my struts-config.xml,
in the matter fact, I did get all other form-bean field setting back form
HTML form except this attributes array.
The reason I used the changed indexed tag of html:text for iterate tag, is
recently all the thread on this mailing list regarding for Iterate property
updating all recommend using your changed tag to have text name set like
array items (I.e. attributes[n].value), then sounds like will help to set
this value back to original array on my form bean. I just don't get it how
this will be happen.
I do have all my html:text name set like that way (i.e.
attributes[n].value), but still get nothing setting back to my array, I do
have all the setter method for element of the array.
Do you know how your indexed tag will help on this matters?
Thanks again.
Frank Ling
