For more precision, I had to return an occurrence handle of a non-database entity

Hi,

I am not sure if I remember it correctly, but I believe that you have to declare the operation in the entity themself:

As public operation in the business object model, so an signature is generate for this operation.

Only if you have a signatur for the entity you can pass it through different components.

Best regards

As descrided in the documentation (under the voice Occurrence operation) I found a working solution as follows

- I wrote code in the occurrence operation in the model entity definition

- I compiled occurrence operation signature using  /ceo

and everything works good.

On the contrary, when I use a  "public handle", the handle returned by an occurrence operation is always NULL.

How is the code with newinstance ?

It seems, that the handle is local defined and therefore no longer valid, when the operation returns.

Try to use a component-variable / typ="public handle" for the  newinstance command

and assign this to your out-parameter.

Good luck,

Rik
