I am working with MapImageLayer on map. As i need to update some data i am trying to create FeatureLayer from sublayer. But function Sublayer.createFeatureLayer() returns error "Cannot read property 'clone' of null" . I see that property Sublayer.renderer is null and it causes this error. But i am not sure how to fix it. Any thoughts ?

Sorry for the late reply. Are you still having an issue with the createFeatureLayer() method? Do you have a code sample you could share?

  I solved this by using QueryTask.Get result as FeatureDataset and then just create FeatureLayer with this dataset

    Andriy,
    
    If the renderer is null, you can pass a SimpleRenderer to it prior to calling the createFeatureLayer() method, and it should work.
