af:table bad behavior in JDeveloper/ADF 12c | Oracle ADF

Hi,
Few Days ago, we faced one bad behavior while building IMS New ADF Application.
While Leading Oracle Fusion Discussion Group B Team - Saudi Arabia / Gulf Area, Main issue come from the default behavior of af:table component for 12c Latest ADF/JDeveloper .
Normal Behavior in ADF Project is a disaster in 12c (as before in old versions) but little bit different, in few steps i will show the bad behaviors and How to solve completely with one step.

• create small table with insert statement as attached in SCRIPT.sql attached file in the project url and create it into your default hr schema.

• Create ADF - JSF Fusion Application as usual. 

                    

• Build Business Component from table and drop it as Entity Object and View Object as well based on table created.

• Make View Object in No Rows Mode (VO always in Insert Mode Only).

• Make Normal jsf page dropping VO as a af:table and createinsert method as a button in toolbar facet for panelgrouplayout container.

• we have only one record in our table

• Run the page, press createinsert button and you will face this Error Message !!

• Insert Second Record

• Run Page Again, and press same button, wow it works !!, but there is a another bad behavior, Data Duplicated !!
• but wait, why Data Displayed !!, we created new row only and at same time, VO has no row property activated !!

• sometimes if you have Master Detail Relation Ship and you have af:table for detail one, you will face another problems same as “Second Record is not visible !!” and sometimes Fire Validation Error for Required items however u didn’t leave the row !!

Finally, to Stop all bad behaviors from af:table, please change the Change Event Policy property of Iterator to be Non instead of ppr (in page Def base of page)

Now, you have perfect result ..
