TypeError: getStock is not a function.

[beyaRecords <uz...@beyarecords.com>]

Hi,
I'm sure that this is a simple one but it eludes me at the moment. I 
have 2 identical operations happening both in a jx page as well as a 
validation form:

jx page:

	<jx:forEach var="orderitem" items="${neworder.getOrderItems()}">
	<tr>
		<td class="normaltext">${orderitem.getStock().getItemTitle()}</td>
	</tr>
	</jx:forEach>

and in my formvalidation.xml:

   	<fd:javascript>
			for (var orderitem in neworder.getOrderItems()){ <---------- This 
line is fine.
				if (orderitem.getStock().getItemTitle() == "abcd") { <----- This 
line is causing the error.
					...do something.....
				}
			}
   	</fd:javascript>

The code in the jx page works, but the javascript in the xml file gives 
the above mentioned error message. What am I missing here?

regards

Uzo

Hi,
manages to find a solution guys. The solution is as follows:

			    orderitems = neworder.getOrderItems().iterator();
				while (orderitems.hasNext()) {
					orderitem = orderitems.next();
					if (orderitem.getStockID() == stock_code){
						duplication = true;
					}
				}

Thanks all for your help.

regards

In javascript, the for/in loop is for iterating over the properties of 
an object, not over a collection. So if the return type of 
getOrderItems() is a list, you'll actually be iterating over the 
properties of the list, rather than it's contents. If you rewrite the 
loop as

    var orderitems = neworder.getOrderItems();
    for (var i = 0; i < orderitems.size(); i++) {
        var orderitem = orderitems.get(i);
        if (orderitem.getStock().getItemTitle() == "abcd") {
            ... do something.....
        }
    }

then it should work for you.

Vil.
