Hi Nicholas
An encoder is a fundamental Tapestry concept, used when you need to bind your
implementation of a translator to a component, it has no effect in this
example. The reason why it is not working is because the value property on the
checkbox is limited to read only boolean (a getter accessor method).
There is no other available property to use, so there is no way that I know of
to bind to a listener/event and reference a corresponding object in the loop.
If anyone knows how, then please share! ...to me this appears to be essential
functionality that is missing.

Perhaps trimming it back to the minimum might help... if it doesn't fix it,
it might help diagnosis.
I don't know why this isn't working.
1) remove the id attribute from the checkbox. T5 will generate one, and it
will be unique
2) remove the encoder. Just because _I_ don't understand it... and I don't
see why you need it.
a) temporarilary remove any code in the loop that relies on the
encoder.
3) stack trace & more code
let us know.
