I have one method getComponent. I am calling this method two times. Once at the time of page loading and another time at the time on the onchange event.
Problems: At the time of pageloading the getmethod component will work and Javascript side shows values.
But in case of an onchange event it doesn't work. It throws:
System.JSONException: Malformed JSON: Expected '[' at the beginning of List/Set
