DynaActionForm does not retain the values submitted

[Vili Leonardo]

Hi,

I have an array of QuoteItem object stored in a DynaActionForm. The QuoteItem is a bean with the following setter and getter for these properties: partID, partDesc, partUOM

and partQty.

This is a definition of the DynaActionForm

<form-bean name="QuoteItemForm" type="org.apache.struts.action.DynaActionForm">
<form-property name="quote" type="com.leonardo.oms.QuoteItem[]"></form-property>
</form-bean>


The rendered html looks like this:

<form name="QuoteItemForm" method="post" action="/coco/processQuoteItem.do?display=true">

PartID: PA123
: art 123
: C</br>
Part Qty: <input type="text" name="lineItem[0].partQty" value=""></br>

PartID: PA234
: art 234
: C</br>
Part Qty: <input type="text" name="lineItem[1].partQty" value=""></br>

PartID: PA456
: art 456
: C</br>
Part Qty: <input type="text" name="lineItem[2].partQty" value=""></br>

<input type="submit" value="Create Quote">
</form>

I entered the qty values and submit the form, the ProcessQuoteItem.action that processes the form is:

public ActionForward perform( ActionMapping mapping, ActionForm form, HttpServletRequest request,
HttpServletResponse response) {

//Get the form
DynaActionForm df = (DynaActionForm) form;
ArrayList arrListQuote = new ArrayList();

//Create session object
HttpSession session = request.getSession();

//get the QuoteItem array
QuoteItem[] lineItem = (QuoteItem[]) df.get("quote");

for(int i=0; i<lineItem.length; i++ ){
if(lineItem[i].getPartQty() != null){
arrListQuote.add(lineItem[i]);
System.out.println(lineItem[i].getPartQty());
}else{
System.out.println(lineItem[i].getPartQty());
}
}

session.setAttribute("arrListQuote", arrListQuote);
return (mapping.findForward("success"));

}

The problem is lineItem[i].getpartQty() does not retain the qty values that are submitted with the form. The system.out shows blanks. Where do I go wrong? Any tips or hints...

TIA

I don't think I've ever seen an ActionForward coded out before, so I'll assume you know what you're doing with that one.

I do recommend using:

HttpSession session = request.getSession(false);

as this will prevent many possible debug frustrations.

Hi,

Basically, I want to build a dynamically sized form. I follow an approach outlined in this article.

http://www.developer.com/java/ejb/article.php/3321521

Is this the right way of creating dynamic sized form?

Thanks
