>    Affects Versions: 5.4

> Since 5.4, the Select model has to be regenerated server-side on submit (unless secure="literal:never"), else you'll fail with model bound to null. 
> If you're chaining AJAX Selects this is a pain - the workaround is to indiscriminately regenerate all of them in onActivate().
> Perhaps it would be better if each AJAX Select bubbled up a PREPARE event  so the container can prepare the appropriate model(s) before you handle VALUE_CHANGED.
