I want to pass a block of rendered html as a component parameter.  After 2hrs searching I have been unable to find the right doc or example.  I have a suspicion that it may involve creating a render() handler, but I'm hoping there's a simpler way.


public class Layout {

  @Property

  @Parameter(required = false)

  private Block headerContent;

}


layout.tml >> EOF

<!DOCTYPE html>

<html lang="en" xmlns="http://www.w3.org/1999/xhtml"

      xmlns:t="http://tapestry.apache.org/schema/tapestry_5_4.xsd"

        >

  <body>${prop:headerContent}</body>

</html>

EOF


page.tml >> EOF2

<html t:type="layout" title="site Index"

      xmlns:t="http://tapestry.apache.org/schema/tapestry_5_4.xsd"

      xmlns:p="tapestry:parameter"

        >



    <p:headerContent>

    content rendered at page level

    </p:headerContent>

</html>

EOF2


expected output >> EOF3

<html>

   <body>content rendered at page level</body>

</html>

EOF3


actual output >> EOF4

<html>

   <body>Block[Parameter headerContent of Index:layout, at classpath:com/example/pages/Index.tml, line 6]</body>

</html>

EOF4
