[jira] [Created] (TAP5-2247) AJAX Select could bubble up PREPARE event

Geoff Callender created TAP5-2247:
-------------------------------------

             Summary: AJAX Select could bubble up PREPARE event
                 Key: TAP5-2247
                 URL: https://issues.apache.org/jira/browse/TAP5-2247
             Project: Tapestry 5
          Issue Type: Improvement
          Components: tapestry-core
    Affects Versions: 5.4
            Reporter: Geoff Callender


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.
