> Certain expressions do not parse when using the DateTimePicker tag. This same expression works fine with the textfield tag:
> The following line throws a parse exception.
>         <s:datetimepicker name="aList.get(%{#attr['item_rowNum'] - 1}).startDate" />
> whereas this works fine:
>         <s:textfield name="aList.get(%{#attr['item_rowNum'] - 1}).startDate" />
> The problem seems to be that the latter uses the standard UIBean evaluateParams()  implementation whereas the former overrides it. This caused a problem with a third-party component as well. Based upon code usage, I believe this may affect other components as well. The following patch should fix both built-in as well as third-party modules:
