POP + javascript :doesn't save to the session

Question

hello,
I have a select list and a popup. I'm trying to assign the value to the POP item using javascript but it's not working.
Here is the Link: [link |http://apex.oracle.com/pls/otn/f?p=11910:1:1730577978881661::::: ] .
Select any value in LOV ID. observe "mnually set" appears in the POP.
click "submit". Validation " not null" will fail...
Here is debug and javasript:
Session State: Save form items and p_arg_values
0.04: ...Session State: Saved Item "P1_LOV_ID" New Value="2"
0.04: ...Session State: Saved Item "P1_AJAX" New Value="21"
0.04: ...Session State: Save "P1_TEMP" - saving same value: "2"
0.04: ...Session State: Save "P1_LOV_SUBMIT" - saving same value: "%null%"
*0.04: ...Session State: Save "P1_POP" - saving same value: "undefined"*
0.04: Processing point: ON_SUBMIT_BEFORE_COMPUTATION
<skip>
javascript:
function set_Value_LOV(pThis,pSelect){
var l_Return = null;
var l_Select = $x(pSelect);
var l_Value = " Manually set" ;
l_Select.value = l_Value ;
The LOV defined in POP is static and has one line.
the interesting caveat:
in IE 7 the validation fails. in FF3 the field has "undefined" string and apparently this doesn't' fire up the validation. At the same time it should be "manually set"....
Maybe i should use some other property of the POP DOM object to actually set the value ?
Please help

Hello Andrey,
>> i love Oracle, but, man, this is sick
First, I’m sorry I didn’t have time to check your example sooner. It happens sometimes, you know your day job … :)
Secondly, your popup problem, not saving session state, has nothing to do with Oracle or APEX. It’s actually HTML.
The type of popup item you chose to use sets the item to a disabled state – you can see that the content of the field is gray. Disabled items don’t get to be submitted to the server – this is the HTML part - hence session state can’t be saved – directly – using this item. That is the reason for the other item, the hidden one. This is a regular item, which gets to be submitted, and the APEX engine takes its value and set it as the session state of the original popup item. In your case, your JavaScript code only updated the disabled item, so the session state source remained empty.

Arie.
