Dear
...
all,
...
I am developing a plugin which i would like to use the "elementselect" type to make my list dynamic as the LoadFormOptions So I have used the property: options_ajax to implement
But when I configure the plugin in UI it said NoClassFound
json of the plugin 
StFunciton is the interface I have created
public class StInterface extends DefaultApplicationPlugin
public class StCreateAccount extends StInterface implements StFunction
The error is ClassNotFoundException
Do anyone have some ideas about this?
Or give me some advice of how to use the options_ajax property of the elementselect field?
PS I am using Joget V3

Jianan
