Page is not inserting data in the table ??

I created a Card Page which has a Page Part (Of type list). My problem is that in my Part page I cant insert any Rec. The Part Page allow me to enter the new row but once I refresh the row disappear.

I checked all the followings:

  1. My Page allow insert

  2. There is no code on the target table which deletes my new Rec

  3. I have fill the Primary key and still after inserting the row and then press F5 (Refersh) My recorded disappeared.

Whats wrong here ?

I found the issue, My part Page had the wrong type. It should be of type “ListPart”
