Hi,

i had the attached source for my service. My problem is on windows this
service works realy good and my navigation tree is displayed fine.

I work with 2 resources. (resJahr and resPerson) All things that are in
the second resource are not displayed in Linux.

On my navigation tree i use a AdapterFactoryContentProvider. Can this be
the problem?

Can someone take a look at my file. Please have a special look at
resJahr and resAlles.

If i change the things like in the TeneoLibraryPersistenceService2.java
its the same problem.

Thanks Waldi

Hi Waldi,
You say not-displayed, but did you debug down into the resPerson resource in case of linux? Is the resource contents
empty? Or is it more an issue on the UI side you think?

Ok sorry. It was my faul. I check out a wrong version of the Model from
the SVN SORRY. It is boring. Forget it. Embarrassing (Red Head).

Hmm ok.... Now, if it no problem for you, I would ask another question:

I try this:

private void removeTeilnehmer(zlvp.Gruppe gruppe, Person teilnehmer){
Command cmdRemove = RemoveCommand.create(p.getEditingDomain(), gruppe,
ZlvpPackage.Literals.GRUPPE__TEILNEHMER, teilnehmer);
Command cmdAdd = new
AddCommand(p.getEditingDomain(),p.getResourcePerson().getCon tents(),teilnehmer);
if (cmdRemove.canExecute()) {
if (cmdAdd.canExecute())
{
p.getEditingDomain().getCommandStack().execute(cmdRemove);
p.getEditingDomain().getCommandStack().execute(cmdAdd);
}
}else{
System.out.println("Hat ned geklappt");
}
}

1Gruppe-N Persons (I had change my model)

But all my Persons get deleted in the database. But I would only delete
the association. How can I do it?

With a 1Group:NLeiter:1Persons the command work realy fine.

Sorry again for the circumstances.....

Hi Waldi,
Sorry, I am not sure why but I had not yet answered your post....

I am not sure but I think Leiter-Person is a containment relation? Then Teneo will automatically map this as a delete
and orphan-delete cascade setting. You can see the hibernate mapping to check this.
If you don't want this then there are two options:
- set a OneToMany annotation with the specific cascade you want
- set the PersistenceOptions.CASCADE_POLICY_ON_CONTAINMENT (this is currently set to ALL, mening also orphan-delete)

This last option influences all containment relations.
