OGNL bug in org.apache.tapestry.binding.ExpressionBinding ?

           Summary: OGNL bug in
                    org.apache.tapestry.binding.ExpressionBinding ?
           Product: Tapestry
           Version: 3.0
          Platform: PC
        OS/Version: Other
            Status: NEW
          Severity: Critical
          Priority: Other

Hi,

 Using Tapestry rc1, i've got a problem with OGNL inside a component.
 This component display an Image who's url is stored in a bean.
 If I write this for binding:

<component-specification allow-informal-parameters="no" allow-body="no">
   <parameter direction="in" type="com.proto.Handset" 
name="toDisplay"/>

 <component id="phoneImage" type="Image">
    <binding name="image" expression="toDisplay.pictureUrl"/>
  </component>
</component-specification>

OGNL is fine but I've got an error because toDisplay.pictureUrl is a String 
and the Image component expect an IAsset. OK No problem, I add a method in 
the Page object to do the conversion.
So I now have an expression like that:

<component id="phoneImage" type="Image">
    <binding name="image" 
expression="page.createRelativeAsset(toDisplay.pictureUrl)"/>
  </component>

And now I've got an OGNL error "toDisplay property not found !" Ouups ? What's 
wrong here ?

I finally managed to make it work with a temporary variable, like that :
<component id="phoneImage" type="Image">
    <binding name="image" expression="#url=toDisplay.pictureUrl, 
page.createRelativeAsset(#url)"/>
  </component>

But this solution doesn't seem to be very elegant.
