packages created by api do not appear in EA

[db]

Hi,

I'm trying to create new packages from C# in an existing .eap file. My code looks like this:

Code: [Select]

 EA.Repository r = new EA.RepositoryClass();

  r.OpenFile(@"****.eap");

  EA.Package new_pack = (EA.Package)r.Models.AddNew("NEW_MODEL", "NONE");
  new_pack.Update();
  r.Models.Refresh();
  r.CloseFile();
  r.Exit();


After running this code i'm expecting to get a new root node in the existing file however when i'm opening EA i only see the the original root node (created in EA). I'm sure that the new package is created and is saved to the .eap file because if i run my application more than one time r.Models.Count is increased after each run and if i loop trough the Models i can see the ones i added.

I didn't find any "isVisible" property for EA.Package and searching for the API created package in EA returns nothing.

Am i doing something wrong?

EDIT: the posted code works fine i was writing to a backup copy and checking the original with EA. Sorry for wasting your time.

RTFM: Models

Read only. Models are of type package and belong to a collection of packages. This is the top level entry point to an Enterprise Architect project file. Each model is a root node in the Project Browser and can contain items such as Views and packages.

db, all collection properties are marked as readonly.

You can't

Code: [Select]

r.Models = differentCollection
You can

Code: [Select]

r.Models.AddNew("Something", "")
