special variable

Is it necessary that combobox must have special variable to hold special value?

Hello Lovish,

The Special Variable is not necessary.
But if you don't use it, you will not be able to define which value from the Special List the user selected, if there is more than one value.

THe behaviour is: 

If the user selects an item from the normal list, the combo stores (usually), the ID in the variable bound to it, and the default value in the special variable.
If the user selects an item from the special list, the combo stores NullIdentifier() in the normal variable, and the value in the special list.
