null pointers after user hits enter in AJAX form

[Qbyte Consulting]

An unrecoverable error occurs after the user hits Enter key in a form
rendered by an enclosed component.

Is there a way to ignore the enter key and not submit the form? It's an
AJAX search value input, not a regular form for submission, so Enter key
hits should be ignored.




<form t:type="form" t:autofocus="true">
<t:UsersComponent t:selectedUserId="selectedUserId" t:zoneId="editZone" />
</form>
