Hi all,

I have a component in my app that had a WOForm nested inside a
WORepetition to submit OrderItems to a manufacturing schedule. One
form for each OrderItem, each with it's own submit button. I thought
I could make the page much more efficient (from both the user's and
the application's perspective) by having just one form that the user
selects which items they want scheduled. The way they indicate what
OrderItems they want scheduled is by changing an item's
quantityToSchedule from null to some quantity.

In wicth way?

The only form field in the form is the repeated quantityToSchedule.

Ok, and what kind of form element is it? input Text? Select? Submit button?

It is a simple text input field that is empty when the page is drawn, but they can add a value to if they want it put on the schedule.

The quantityToSchedule value is NOT an attribute of OrderItem, and
I'm not actually updating OrderItem, I am using the information from
the submitted form to create new instances of the ScheduledOrderItem
entity.

When I submit the form, I get a null pointer exception when I try to
pass the instance of OrderItem that is bound to the WORepitition's
"item" binding (aOrderItem). Am I doing something obviously wrong?

mmm, sorry but I've not understand very well the structure of your form, ca you give a little example?

<WOForm>
<WOSubmitButton action="">
<WORepetition list=openOrderItems, item=aOrderItem>
<WOString value=aOrderItem.Order.DueDate>,<WOString value=aOrderItem.Part.PartName>,<WOString value=aOrderItem.orderQuantity><WOTextField value=quantityToSchedule>
</WORepitition>
</WOForm>

In the component.java file I have have the following variable and method:

protected BigDecimal quantityToSchedule();

quantityToSchedule() {
return null;
}

ehm, I think you miss the setQuantityToSchedule(BigDecimal decimal) method

for example:

private BigDecimal _quantityToSchedule;

public BigDecimal quantityToSchedule()
{
return _quantityToSchedule;
}

public void setQuantityToSchedule(BigDecimal decimal)
{
_quantityToSchedule = decimal;
}

then when you bind <WOTextField value=quantityToSchedule> this should work!

Thanks,

Dave
