Okay, I added a setQuantityToSchedule method, but I still get the
NullPointerExeption.
Here's the method I'm actually calling in the action binding of the
WOSubmitButton:
public WOComponent addOrderItemToSchedule() {
ec = session().defaultEditingContext();
log.debug("OrderItem to Schedule: "+aOrderItem.part().partName());
((ManufacturingSchedule)manufacturingSchedule).scheduleOrderItem(ec,
(OrderItem)aOrderItem,
quantityToSchedule);
return context().page();
}
I get a NullPointerException on the log.debug statement, or if I
comment it out, on the scheduleOrderItem() call.
So you have 2 problems: manufacturingSchedule is null, and or aOrderItem is null or aOrderItem.part() is null
Here's the bindings of the WOTextField:
quantityToSchedule: WOTextField {
numberformat = "0";
size = 5;
value = quantityToSchedule;
class = "small";
}
What am I missing? Why does this work just fine if I have one form
for each aOrderItem, but when I try to have one form for ALL of them,
I get the NullPointerException.
