Howard M. Lewis Ship resolved TAPESTRY-1486.
--------------------------------------------
Resolution: Invalid
Please check the message: "could not find a component" ... Label does what it
normally does, interpret the for parameter as the id of a component (using a
default prefix of "component:").
The for parameter has to be a component.
You probably want to bind the label parameter of the TextField component.
