I am trying to create a new value editor by taking existing MultiValueEditor but somehow I am getting an error while instantiating MultiValueEditor class.
Steps I have followed :
1) Copied DN editor source and configuration and replica the DN editor as MultiValue editor
2) in plugin.xml of value editors package, I have modified like below
3) I am able to see new editor in edit value preferences but when choose and edit the value I am getting attached error.
I understand one thing in plugin.xml of value editors supporting only AbstractDialogStringValueEditor its throwing error if try to extend CellEditor. could you please explain to me how to use multivlauededitor to edit multi values.
