Lov iterator refresh issue

Question

HI friends!
I'm using JDeveloper 11g
I've got a problem with a lov attribute in my application.
I need to implement the following scenario:
I have an adf table Licence in my jsf page. One of the table columns includes a lov attribute which values must be selected from a list box (a list data source is LicenceProducer lov view object).
If there is no required licence producer in the drop down list we can trigger a pop up dilaog (kind of lov dialog) and create a new one row in the data source iterator.
Then the required attribute value of the newly created row must be passed to the list in the source jsf page and become a currently selected value for the lov attribute of the Licence VO.
SO i've have implemented almost the whole scenario:
1. created an appropriate lov attribute in Licence VO with LicenceProducer VO as a list data source
2. created a bounded adf task flow which is resonsible for displaying the pop up lov dialog with all insert/commit/return new value functionallity.
Everything works just greate except that the lov iterator is never refreshed after returning from the pop up dialog.
The updated content of the list box is only seen after reloading the source jsf page. Setting partial page rendering (for the Licence adf table) on returning from the pop up dialog does't work.
I saw a number of posts on this issue but never found any good solutions.
I think that i must somehow get an access to the lov iterator (data source vo) wich is not the same as the base LicenceProducer view object and refresh it programmatically.
PS. if i brought my issue in a not sufficiently clear way. please answer the quite simplier question. Is it possible somehow to add a lov functionallity with the possibility to add new rows into lov iterator?
Thanks in advance. Alex.

Thanks friends.
It is so greate to see somebody notice your question and even have the similar problem.
First to Paul
1. Yes I have a model driven LOV, i.e. i defined the lov functionalty for the attribute in a VO.
2. I'm using JDeveloper 11g as you might be using.
3. Actually i'm afraid i have not fully understood your approach with a row impl class. AS i could notice there were no worthy changes added into the row impl class after i had redefined VO's attribute to use a lov view object.
it would be greatly appreciated if you let me know more detail about your solution.
By the way i have noticed one interesting thing as I was experimenting with my issue. It turned out that the lov iterator refreshes just excellent on returning from a pop up "manually created lov dialog" after i click a rollback button of the data control
where the VO iterator containing the attribute with the lov functionalty exists. Give it a try and you'll see, no other standard operation button gives the same effect!!!!! I realized it accidentially myself.
To Hasim
if i understand you right your assumption is to refresh a row iterator which is the basis for the lov attribute and then refresh a page element where the lov attribute has been dropped?
If so than i've tried it because this is the first thing comes into mind. But it doesn't work, i think that this basis iterator we select for the list of values of the required attribute in VO is not the same as a real list Datasource iterator...
If i understood you wrong please give me know and explain please your approach. Your opinion is interesting for me.
I address our experts ones again with a rather simplier question. Is it possible to create a model driven lov attribute where it would be possible to insert new rows into the list of values during the ongoing user session?
Alex.
