Jesse Kuhnert resolved TAPESTRY-1076.
-------------------------------------
Fix Version/s: 4.1.1
Resolution: Fixed
Regardless of the ultimate validity of the component type passed into the
parameter the error message presented is extremely deceptive.
I've fixed this now to tell you what you gave it and what it wanted.. This is
definitely one of those "quircks" we can do without.
Thanks for reporting it! :)

> I have a component witch wraps a tapestry "TextField".
> Something like this just as an example...

> <input jwcid="[EMAIL PROTECTED]"/>
> </body>

> If I use this component with a Label in a form like this...
> <form jwcid="[EMAIL PROTECTED]">
> <label jwcid="@FieldLabel" field="component:comp1"/>
> <input jwcid="[EMAIL PROTECTED]" displayName="Field description"
> value="ognl:data" />
> </form>
> I get the following error:
> "org.apache.tapestry.BindingException
> Error converting value for template parameter field: No type converter for
> type org.apache.tapestry.form.IFormComponent is available."
> Seems like it need the form component and is trying to get it as the parent
