[5.4-beta-6] Form always produces this error: "Selected option is not
listed in the model"
I found that my event-handler to handle a form's successful submit is never
fired. I have a very simple form that has one text field and select
component.
I included *<t:errors/>* (What is this actually called ? A component ? A
block ?) to display the form's errors if they exist and I was surprised to
find this error:
*Selected option is not listed in the model*
My value encoder always returns a valid object based on the client-side ID,
so what could be the reason for this error ?

Writing an equals() method is something widely recommended in Java, not
just Tapestry, specially for objects that end up in collections, as that's
the case with the Select component (SelectModel doesn't implement
Collection, but semantically it is a collection).

Fixed. I had to implement the equals method !
I did this out of mere guessing, is this stated somewhere in the docs ? I
admit I haven't been reading the docs since v5.2 may be.

A component. That's why I call it the Errors component instead of
<t:errors>, not to mention I prefer the <div t:type="Errors"> syntax.
Blocks are declared using <t:block>.
