I agree.

Now the tmp datasource needs to be modified. which in turn sets the process-state to reload-required. Further :test-connection-in-pool() operations will fail until the server is reloaded. Doing that in the middle of the "Create Datasource" wizard is neither user friendly nor obvious for the user.

The user would still be able to test the connection once it was created. Currently this can be done in both the configuration and runtime section. When revisiting this feature, I would also like to remove the test connection feature in the configuration section as it clearly belong to the runtime section.
