Master Details form (LOV based on Detail Column of Join Condition)

Question

I have created a master detail form where user_id is joining master and details.
I have created one dynamic lov based on child user_id in detail block to diplay all user who works under current user.
Problem : When i want to select Insert detail action in detail block the dynamic lov should read the user_id which is going to be inserted when you press Save button. Means as its not getting populated till one click on save button my lov is not getting refereshed.
Please advice what should i do.
Thanks

I solved myself by modifing some guru's script from this forum little bit. I am adding here for feedback or use to any.
htp.p('<script language="JavaScript1.3">
function getMstFieldValue(form,fieldName)
var objName = "";
var tmp = "";
var dAction = "";
var sel_idx = 0;
var cnt = 0;
var instance = 0;
var slicedName;
var fillData = new Array();
var blkname;
for(var i = 0; i < form.length; i++)
slicedName = form.elements.name.split(".");
tmp = slicedName[2];
instance = parseInt(slicedName[3],10);
blkname = slicedName[1];
//alert("Fld "+tmp+" blk "+blkname+ " instance "+instance);
if (!tmp)
continue;
objName = tmp;
if (objName == fieldName && blkname == "MASTER_BLOCK")
return form.elements[i].value;
function setDetFieldValue(form,fieldName,value)
var objName = "";
var tmp = "";
var dAction = "";
var sel_idx = 0;
var cnt = 0;
var instance = 0;
var slicedName;
var fillData = new Array();
var blkname;
for(var i = 0; i < form.length; i++)
slicedName = form.elements[i].name.split(".");
tmp = slicedName[2];
instance = parseInt(slicedName[3],10);
blkname = slicedName[1];
//alert("Fld "+tmp+" blk "+blkname+ " instance "+instance);
if (!tmp)
continue;
objName = tmp;
if (objName == fieldName && blkname == "DETAIL_BLOCK")
form.elements[i].value = value;
</script>');
