>                 Key: WW-5451
>                 URL: https://issues.apache.org/jira/browse/WW-5451
>             Project: Struts 2
>          Issue Type: Bug
>    Affects Versions: 6.4.0
>            Reporter: Jon Pulice
>            Priority: Minor
>
> When the first entry in an array contains a null value, and that array is used as the source for an <s:iterator> tag, a NullPointerException is thrown. This exception did not occur in prior versions of Struts 6.x
> Exception:
>  
> {code:java}
> ERROR org.apache.struts2.dispatcher.DefaultDispatcherErrorHandler - Exception occurred during processing request: null
> java.lang.NullPointerException: null
>     at org.apache.struts2.components.IteratorComponent.start(IteratorComponent.java:309) ~[struts2-core-6.4.0.jar:6.4.0]
>     at org.apache.struts2.views.jsp.ComponentTagSupport.doStartTag(ComponentTagSupport.java:51) ~[struts2-core-6.4.0.jar:6.4.0]
>     ...{code}
>  
>  
> A trivial example would be this tag:
> {code:java}
> <s:iterator value="pages">
>     ...
> </s:iterator>{code}
> and Action:
>  
> {code:java}
> public class TestAction extends ActionSupport {    
>     private Object[] pages = null;    
>     
>     public String prompt() throws Exception {
>         pages = new Object[10];
>         return SUCCESS;
>     }
> }
> {code}
>
