1..n in component controller.

Hi ,

If you will remove the space in the dropdown then the first value of the drop down will get selected.

You can remove the empty space by replacing the empty space by "Please select". Replace your code

from

valueSet.put("","");

to

valueSet.put("Please Select","");

set the selection property of the dropdown as 1..n.

if the error is still existing.

create a new node .

retrieve the values from the RFC ,remove the null entry and assign the other values to the new node.

Try by Changing the cardinality of the node to 1..1 or 1..n

Hi,

Take DropDownBYIndex UI element and check the singelton and cardinality of the root node as 1..1 and 0..n

This may solve your problem
