How to get the value of selectManyListbox component using ParameterMap object
posted 9 years ago
I am using SelectMayListBox component in my jspx. I want to get the value of this component which is List or array in my action class. ( Here I want this value without submitting the form so I used ParameterMap in my action class.)
The third line in the code throwing ClassCastException. I tried to replace List with String then also same thing happened. But when I put String instead List it didn't throw anything. But in this case I can get only one item selected by the user. How can I get the list in my action class?
