Cardinality of the Context Node

[Former Member]

Hi,

I have created a Parent node with a cardinality 0..n & i have added two more child nodes to this Parent node with same cardinality 0..n & one element. Also child nodes have multiple elments also.

I have written the code in DoInit Method...of my only iview...

public void wdDoInit()

{

wdContext.currentOrderDataElement().setFirstName("Smita");

wdContext.currentDataSourceElement().setSalutationText(salutationText);

wdContext.currentOrderDataElement().setCustomerID(2121);

wdContext.currentOrderDataElement().setOrderID(5245);

IPrivateDynamicFormView.IOrderItemsElement orderItemsElement = wdContext.createOrderItemsElement();

orderItemsElement.setProductID(90);

wdContext.nodeOrderData().addElement(orderItemsElement);

}

when i try to Run it i am getting following exception..........

<b>java.lang.NullPointerException</b>

Thanks in advance !!

hi Smita,

The proposed cardinality for parent node should be 1:n & for Child nodes it should be 0:1.

Thanks,
