Dynamic Refresh Region with APEX 4.0

Question

Greetings!
With APEX 4.2, when you want to refresh a region that depends on an page-item-value, there are different ways to submit that item with the dynamic action ("Page Item zu Submit"). But this is not imcorperated in APEX 4.0 yet. Is there a way to work around that? I have tought about an apex.submit({...}) call, but I am not sure, where to insert it, also that would be a.. well... submit, not ajex.
Thanks for any help,
so long,
tobi

Thanks for the hint, but its still not working. I have another item, that gets the value of the item passed to on key-up event. This works. But no refresh of the region.
My setup looks like that now:
Event: Key Release
Selection Type: Item
Item: ... an auto complete text field
Condition: is not null
True Actions:
1) Action: Execute PL/SQL Code
 Fire on Page Load, Stop exec on error
 PL/SQP Code: null;
 Page Items to Submit: ... that same autocomplete field
2) Action: Refresh
 Fires on Page Load
 Selection Type: Region
 Region: ... the report region with the where clause comparing the text field.
The identical action I created for the Get Focus Event, because that happens, when the user clicks on the dropdown list to select an item, then the text field gets focused again. Thats when I want the report to update.
Only when I hit the enter key (what I actually dont want to happen, and thats another issue) the page gets submitted. Then the report is displayed with the new selection. But I dont want the user to wait for the page reload process.
