When set on a structure-field array, the property numElementsItem identifies a PageHandler field whose runtime value specifies the number of array elements to display. The property is used only for output and is meaningful only if set on a fixed-record structure field that has an occurs value greater than 1.
The value of numElementsItem is a string literal that identifies the name of a PageHandler field. The property is not valid for a dynamic array, which includes an indicator of how many elements are in use; for details, see Arrays.
