Hi

The node is used to store the set of values.with the use of node you can create the UI elements like Table, Dropdown etc..

For cardinality See the thread

Kind Regards

Hi,

Value Attribute is having the value in a single attribute.

Value Node is having multiple value in a single attribute.

To have multiple values we have to cteate elements for that node and each elements will have each values set with that attribute.

Code to create element and set values to it:

IPrivate<view name>.I<node name>Element element = wdContext.node<node name>().create<node name>Element();
wdContext.node<node name>().addElement(element);
element.set<Attribute>();

Cardinality:

It defines the no of elements in the node.

for 1:1 or 1:n one element is already created and u can set the values directly.

For 0:1 or 0:n we have to create the element and then set the values.
