Bug 1:
It appears that certain characters in previous values defeat the dynamic choice list functionality. When you dropdown the list box or start typing the busy icon starts up, quits and no choices are displayed.
I captured the XML returned and found that the '&' character wasn't escaped properly. There may be others as I only found the problems I had.
Bug 2:
I have a Number field with dynamic choices. I type a value (or try the dropdown) and I capture this result :
<root>
<get_dynamic_choices_action_return>
<failure>java.lang.Double cannot be cast to java.lang.String</failure>
</get_dynamic_choices_action_return>
</root>
