Help with Master/Detail app. when the database tables are empty?

Hi,

I have created a master / detail application and the master table and the detail table do not have any records. I can create the application without problem and as I need it only for new records entries, I configured it to start in insert mode.

Now the problem I have is that the detail is not shown until I record data in the master, that is, until I click on the save button. Until then, the application shows me the empty detail so that I can add records in it.

Is there a way to create a master / detail application that stores the data in memory and that the data is recorded only if the save button is clicked?

thanks for your help,

Aldo
