Hi
 
I've got a class EntityBase which inherits from Entity and it is one of my Injected Base Types. I want to create another inject base type which inherits from my EntityBase class.
 
I click on the Injected Base Types and add a new new type. It gets generated, but does not appear in the drop down which lets you assign it to the entity as it's base type.
 
Why is this so? Is this a limitation of devforce, that you have to directly inherit from Entity instead of inheriting from a class that inherits from Entity?
 
Cheers
 
Jacob

You cannot use the Injected Types dialog to make, for example, Order inherit from OrderBase and OrderBase inherit from BaseEntity. We stopped short of providing facilities to define multi-level inheritance stacks in the Injected Types dialog in order to keep the UI simple.

If you need to do the above, do the following:

Here is the relationship we are trying to establish:
Order -> OrderBase -> BaseEntity -> Entity, where -> signifies "inherits from"

1. Open the Injected Base Types dialog and create OrderBase and BaseEntity which both inherit from Entity.

2. Make BaseEntity the default. Click OK to close the dialog.

3. Set Order to inherit from OrderBase.

4. Save and generate the model.

5. Manually change the OrderBase developer class to inherit from "BaseEntity" (originally it should inherit from Entity).

Hi Eileenv,

I don't know exactly about this behavior of Injected Base Types, Thanks for clarifying your answer.
