Form Field updated on open

weblike

Hello,

In previous post I asked a newbie question, but I figured it out after little documentation.

Now I hope this is not stupid like the previous, but after reading, watching tutorials still can't figured it out..

I have an Order APP, with Orders and OrdersDetails BO's.

When I make them Peer Relationship the creation form it's working fine. When I create an order, in the same time I can add order_details..

If I make the Owner/child relationship between BO's ...I have to create the Order first-> save it -> only after this I am able to enter the order_details...

OK..Why I want the Owner/child relationship? Because like it's says in docs...when deleting order..all child order_details are deleted...and I don't want my DB to be messy when users begins to add/modify/delete orders...

When I open the Order form the OrderID in the form is not updated. I tried to use some rules to update the OrderID when I open the form but no luck...
I have this rule:
IF Order IS NEW THEN Order.OrderID=MAX Order.OrderID+1

I guess I have to add one more rule..but don't no what yet..
Thank you

You should be able to create related objects without having to save the order first regardless of relationship type - you don't need any special rules for this. I cannot say what's wrong if it doesn't work for you.
