| How to create a new EMF child object (that is properly linked into the model)? [message #428107] |

I have an object that is JobListType and I want to create another
object that is JobType and get it properly inserted in my EMF model
with the JobListType object as its parent.
In the example below, my model is called TestExplorer, and "object" is
of type JobListTypeImpl
// get the adapter factory
TestExplorerItemProviderAdapterFactory af =
(TestExplorerItemProviderAdapterFactory)adapterFactory.getFa ctoryForType(object);
// get the item provider
JobListTypeItemProvider ip =
(JobListTypeItemProvider)af.createJobListTypeAdapter();
// create the new JobType item
JobType newJobFile = TestExplorerFactory.eINSTANCE.createJobType();
I see that this just created a new item, but did not make "object" its
parent. How do I get object associated with it? I searched around
and found commands like CreateChildAction and CreateChildCommand, but
I couldn't find any examples of how they are used--and it was asking
for a bunch of parameters I didn't know how to fill in.
There must be a simple way to create a new child object from another
object--could someone point me in the right direction?

object is an instance? I'm not sure this makes sense...

Hmmm.

Of course not. The create method creates a blank new object that's not
related in any way to any other objects, yet.

Is there some object.getJobs().add(newJobFile) you can use?

It's odd that you seem to be mixing the EMF Edit stuff with the basic
model manipulation stuff....

I'd expect that object, being of type job list would have a getJobs()
method that returns a list and that you could add a newJobFile to it.
Of course in the generated editor, you'd have the option to create a new
child job for it, right?

Thanks,
It looks like using the following does what I wanted:
((JobListTypeImpl)object).getJob().add(newJobFile);
