RE: Long Story short
Hi
Dave, let me tell you this, if you are ever in
my neighborhood beers on me :-)
Finally i got it working, what i didnt realise
was that i had to split up the action in the
show and save parts, like you do in your code!
... so little hair left, for such a small mistake :-)
This is great, thanks a lot!!

Torsten,
Hi. Please find attached some of my code, as requested in your mail to me
directly (was not a problem!). Here's what I do:
I basically call ShowParameters to get the underlying parameters, and fill the
form, which is in Session scope. User is then presented with parameters.jsp
(note, this is fairly complicated, but you should be able to follow it through).
When they submit the page, SaveParameters is called, and the updated parameters
in the Vector are processed.
Would recommend you try sticking the form in session scope, if you are
prefilling it in another action.
Let me know if I can help further.
Cheers,
Dave

Hi,
Although i have followed the example below i still have the problem with saving
the indexed fields. It is driving me nuts so if anybody who have it working
would
take the time to see if they can spot the error i will be very very greatfull.
The source below is with a vector instead of an array. What happens is that when
the action code is executed the vector in the form is empy although the simple
String
element is saved alright!
My form looks like this:
public final class ParametersForm extends ActionForm
{
// --- Instance Variables
private Vector parameterList = new Vector();
private String tester;
// --- Properties
public String getTester() { return tester; }
public void setTester(String v) { this.tester = v; }
public Vector getParameterList() { return(this.parameterList); }
public void setParameterList(Vector parameterList) {
this.parameterList = parameterList; }
public Parameter getParameter(int index){ return
(Parameter)parameterList.elementAt(index); }
}
The Parameter class used for each row:
public class Parameter {
String key;
String desc;
String value;
public String getKey() {return key;}
public void setKey(String v) {this.key = v;}
public String getDesc() {return desc;}
public void setDesc(String v) {this.desc = v;}
public String getValue() {return value;}
public void setValue(String v) {this.value = v;}
}
The action looks like this:
public final class SaveParametersAction extends Action {
// - Public Methods
public ActionForward perform(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
ParametersForm paramForm = (ParametersForm) form;
// Get the simple tester
String test = paramForm.getTester();
System.out.println("paramForm tester was = '"+ test + "'");
// Get the parameter list
Vector paramList = paramForm.getParameterList();
Parameter parm1 = new Parameter();
parm1 = (Parameter)paramList.elementAt(0);
System.out.println("parm1.getValue():"+parm1.getValue());
// Forward control to the specified success URI
return (mapping.findForward("success"));
}
}
My JSP looks like this:
<%
//cheating to get the objects in the request...
ParametersForm parametersForm = new ParametersForm();
Vector parametersList = new Vector();
Parameter parameter1 = new Parameter();
Parameter parameter2 = new Parameter();
parameter1.setKey("key0");
parameter1.setDesc("desc0");
parameter1.setValue("value0");
parameter2.setKey("key1");
parameter2.setDesc("desc1");

parametersList.addElement(parameter1);

RE: Long Story short
Hi,
Maybe im doing something wrong with this initialisation, but the way
im using this (when i get it working) is that the table gets populated
with data from a database, and this should be editable by the user. I.e.,
i have an action, which based on a single input field, finds the data and
populates the form bean, and stores it in the request just before going
to the parameters.jsp page in the example. I was trying to simulate this
scenario by populating the form bean with some dummy data before displying
the page.
I just tried to do what you say, and what happens is the indexed fields
are not diplayed at all, only the simple text input field, it just isnt
initialised. Am i doing something wrong here? If i need to populate the
form prior to displaying it, can i do it in some other way?!?
Regarding the indexed tag, i dont quite follow you. I am using the indexed
tag, like described on the link you referred to,
...
...
Thanks...
Regards,
Torsten

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:
bean:write name="parameter" property="key"/>
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!

RE: Long Story short
What scope is your ActionForm in - request or session? If its in session scope - no problem, if its request you need to make sure your array is set up with all the beans it requires (empty ones will do).

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.

Re: Long Story short
Hope u have the tag similar to this -
// Here iterate tag is just acting as for loop .No use of scripting variable
"id"
// this will call getProductList ( index) followed by getProductName ( )
<% n ++ %>
Here n is the index variable .No need of using the **indexed iterate tag
** in above case .
Then have methods like
class myForm extends ActionForm {
private Vector productList ;// contains list of Product objects .
public Product getProductList(int index) {
return (Product)productList(index);
}
public void setProductList( Vector list) {
productList = list ;
}
}
The class Product implements Serializable {
private String productName ;
private String productPrice;
// getter and setters
public String getProductName ( ) {
return productName ;
}
public void setProductName(String name ) {
this.prodctName = name ;
}
public String getProductPrice () {
return productPrice ;
}
public void setProductPrice(String price) {
this.productPrice = price ;
}
}
