Hi,

For a form you can put the node cardinaility as 1:. As the form will include only one value to be inputed therefore only one element per attribute is required in the node.

However for a table you have to put its cardinality as 0:n OR 1:n. 0:n means that there can be either 0 elements or n elements which can be created for a node. So can have a scenario that there are no values in the table OR n values in the table.

1:n gaurantees you that you will always have atleast 1 element in the table and then you can create upto n elements in the table at runtime.

I hope that helps. Please revert back in case you need miore information.

Thanks and Regards

Hi Kiran,

Cardinality contians the Minimum& Max number of elements may context node contains at runtime.

0:1 minum 0 &max 1

0:n

1:1

1:n

if you try to delete last element from a node of cardinality 1:n it gives the Exception at runtime.which means it must contain atleast one element.

cardinality of form is 0:1 either no value or atleast one value.

Cardinality of a table is 0:n either no value or it can hold upto n records

Cardinality is the minimum-maximum number of elements possible for a node at runtime.

Hope this helps.
