Error when try change data on execution time

[juanm4]

Hello, I have a problem with library when I try change the data on execution time.
Well, I am trying change the views every minute, I mean, I have a timer that execute next code every minute:
getActivity().runOnUiThread(new Runnable() {
@OverRide
public void run() {
try {
messageArrayList = gson.fromJson(new MessageTask().execute("").get(), new TypeToken<ArrayList>(){}.getType());
customCarouselView = (CarouselView) rootView.findViewById(R.id.carouselView);
customCarouselView.setPageCount(2);
customCarouselView.setViewListener(new ViewListener() {
@OverRide
public View setViewForPosition(int position) {
View custom = inflater.inflate(R.layout.message_template, null);
TextView title = (TextView) custom.findViewById(R.id.title_message);
TextView body = (TextView) custom.findViewById(R.id.body_message);
title.setText(messageArrayList.get(position).getTitulo_mensaje());
body.setText(messageArrayList.get(position).getMensaje());
return custom;
}
});
} catch (InterruptedException e) {
e.printStackTrace();
} catch (ExecutionException e) {
e.printStackTrace();
}
}
});

But, If this code is executed on AsyncTask I get next error:
Theme: themes:{default=overlay:com.wsdeveloper.galaxy, iconPack:com.wsdeveloper.galaxy, fontPkg:com.wsdeveloper.galaxy, com.android.systemui=overlay:com.wsdeveloper.galaxy}
java.lang.RuntimeException: View must set ImageListener or ViewListener.

What happens here?

This error appears just in this line:
customCarouselView.setPageCount(2);

Thanks

First set Listner then set Pagecount
