af:inputDate :: getting ADFFacesMessage error

Question

I am using ADF Faces components in my WebLayer.While using the dateComponent

I am getting some faces message error.Pls find my jsf code

<af:inputDate label="Date" value="#{innerRow.dateValue}"
              maxValue="#{innerRow.maxValue}"
              minValue="#{innerRow.minValue}"  
              valueChangeListener="#{pageFlowScope.myBean.valuechangeMethod}"
              converter="javax.faces.DateTime">
    <af:convertDateTime pattern="#{innerRow.datePattern}"/>
</af:inputDate>

In valuechange method following code is written

valueChangeEvent.getComponent().processUpdates(FacesContext.getCurrentInstance()

Other attributes are from my ManagedBean class

public class MyBean{
  private Date dateValue;
  private Date maxValue;
  private Date minValue;
  private String datePattern;
  // getter & setter
}

Whenever I am trying to pick any date from the calendar I am moving into exception

java.lang.NullPointerException

Answer 1

remove the pageFlowScope at the valueChangeListener
