OA Extension for opportunity create page - Multi Entity Extension

Question

Hello,
i'm trying to achieve a multi Entity Extension.
We are storing additional attributes in a custom table for opportunities. i'm trying to extend the existing Opportunity Create Page to create an other record in custom table.
Here is what i've done.
1. i've defined a new entity object for custom table
2. i've defined a new view object for custom Entity
i'm trying to figure out whether i can use a view link to link OpportunityCreateVO and custom view object. But jdeveloper is erroring out when i try to create a view link.
Moreover i'm wondering whether i'll be able to achieve a multi Entity Extension?
Any inputs will be helpful
Thanks
Mahesh

Answer 1

Thanks for the hint. i could extend the VO and include both the enitity objects.
According to the documentation, i've done the substitution and included new fields in the page using personalization. But unfortunately, row is not getting inserted in the table for the second custom entity object. Is there any additional step i'm missing out?
Appreciate your inputs
