Java.lang.NullPointerException at org.apache.struts.taglib.tiles.InsertTag

Question

I am using tiles with JSF.
my starting page is template.jsp which is like this..
<f:view>
<f:subview id="header">
<tiles:insert attribute="header" flush="false"/>
</f:subview>
<f:subview id="menu">
<tiles:insert attribute="menu" flush="false"/>
</f:subview>
</f:view>
when ever the page is rendered, im not getting the value for attribute header or content. its throwing java.lang.NullPointerException at org.apache.struts.taglib.tiles.InsertTag.processAttribute(InsertTag.java:689)
