I have the following situation:

Im using 2 Tables, and generated teh CRUD for them for GWT 2.1.
In the Detailsview of Entity1 i have to generate Entity2 and save it to the Database.

How to do that ?

Here the relevant Code:

Is there a relationship between your two entities?

If there is, then there should be an example of how to manage the related objects in the edit view.

Thanks,
Jack

Hi !

There is no relation.

I have the RequestFactory in a Singleton, and accessing them globally right now,
it seams to working.

Is there a better was to doing this ?
