My code in the bean is ...
SelectItem[] repIndicator;
public SelectItem[] getRepIndicator() {
          return repIndicator;
public void setRepIndicator(SelectItem[] repIndicator) {
          this.repIndicator = repIndicator;
My JSP page code
<h:selectOneMenu value="#DealerDetails.dealerRecycledRepIndicator}" >
<f:selectItems value="#DealerDetails.repIndicator}"/>
</h:selectOneMenu>      
nw the value in the variable repIndicator is not null... but when i press submit button... then the error above comes i dnt understand why.. the data type of repIndicator is selectType
