Cascading LOV does not work when setting the value of the parent LOV with DA

Question

Hello All,
Using APEX 4.2.2.
I have tow LOVs
Parent LOV item is: P50_TYPE
Child LOV item is :  P50_PROJECT_ID
In other words in the attributes of the item P50_PROJECT_ID we have :
> Cascading LOV Parent Item(s): P50_TYPE
> Page Items to Submit: P50_TYPE
> List of values definition: something similar to:
Select * from mytable where type = :P50_TYPE
I use DA that execute JS code to set the value of the P50_TYPE item
something similar to:
> $('#P50_TYPE').val(2);
Having done this, the P50_PROJECT_ID item does not get refreshed, when the value of P50_TYPE is changed. Namely, P50_PROJECT_ID remains empty, unless end user manually changes the value of P50_TYPE.
Any help please ?
Regards,

Thanks Scott,
By the way, I remember reading a thread posted by you about  Sumneva Drag & Drop Report Region plugin that was answered by Tom . But, I cannot find this plugin anywhere. Does not it supported in APEX 4.2 ? Is there any alternative out there ?
If you use it, and it works find with you, can you please send it to me on [email protected] ?
