[news.eclipse.tools.emf] Re: Create Child programmatically

[addur737@xxxxxxxx (Artur Kronenberg)]

Hi Ed,

thank you for your fast reply. I tried using the CreateChildrenCommand by 
getting a command from the AdapterFactoryEditingDomain but it somehow did 
not work out for me. I don't quite get how to use those commands exactly 
to achieve what I need.

If I would use the 
AdapterFactoryEditingDomain.createCinnabd(CreateChildCommand.class, new 
CommandParameters(owner, feature, collection<?>) what would be the 
parameters for the CommandParameters.

I have my Editor and therefor I could access everything in it. I still 
couldn't figure out how to get the owner for my new object (i supposed 
this should be the parent node?) If I thate the resourceset from my editor 
and iterate through its contents then I can get my rootNodeImpl and get 
all the childNodes and find out where to put my new created node, but this 
seems to be kind of a weird way to achieve this? 

Also, what would be the feature atribute I would have to set there? From 
debuggin I think the collection I have to pass the commandParameters I can 
get by calling getNewChildDescriptors from my editingDomain? 

Thank you for your help.

Best regards,
Artur
