hi,

wdContext.currentRequisition_ItemsElement()

What is the cardinality of the node Requisition_Items.

if its not 1..n then create an element and then access this.

Hi ,

(1)Requisition_Items is not getting populated before you use it.

(2) set collection cardinality for Requisition_Items to 1:1 or 1:n

u need to initialize currentRequisition_ItemsElement in the wdDoInit() and bind to the context node.
