code: public void resetData() {
  		ComponentModel sharedModel = getSharedModel();
  
  		if (sharedModel instanceof DataBoundComponentModel) {
  			Object sharedData = ((DataBoundComponentModel) sharedModel).getData();
  			setData(copyData(sharedData));
  
  			// clear the user data flag
  			setFlags(getFlags() & ~USER_DATA_SET);
  		}
  	}
docs: Resets the data to the default value. Only has an effect for session component models (ie. those with a shared
  model set).
