BindingException

[Rob Dennett]

I am getting a BindingException that says the source is null for 
getProperty(null, “page”) when Tapestry tries to parse the jwc that contains 
this code:

 

      <property name="item" />

 

      <parameter name="menuItems" required="true" />

      <parameter name="cssClass" default-value="literal:menu" />

 

      <component id="menuItemLoop" type="For">

            <binding name="source" value="menuItems" />

            <binding name="value" value="item" />

      </component>

      

      <component id="foo" type="Insert">

            <binding name="value" value="item.page" />

      </component>

 

      <component id="menuItem" type="MenuItem">

            <binding name="title" value="item.title" />

            <binding name="page" value="item.page" />

            <binding name="pageParams" value="item.pageParams" />

            <binding name="subMenu" value="item.subMenu" />

            <binding name="subMenuImage" value="item.subMenuImage" />

      </component>

 

It is blowing up at the second binding for menuItem where page is bound to 
item.page.  If I comment out the menuItem component and the code that 
references it in the template, the foo component has no trouble spitting out 
all the values for item.page.  What gives?

 

Thanks for your help,

Rob Dennett
