[news.eclipse.technology.gmt.amw] Re: model conforms to metamodel: probl

[Marcos Didonet Del Fabro <marcos.didonet-del-fabro@xxxxxxxxxxxxxx>]

Hello,

this question is more related to the ATL discussion-list (atl_discussion@xxxxxxxxxxxxxxx).

You can try two possible solutions to your problem:

1) the AM3 Ant tasks are not designed to load metamodels (or models) the way you try to 
do. These tasks are designed to load models that are going to be transformed (or injected, 
extracted, etc.), within the same Ant script.
However, due to the way this task is implemented, it may be possible to do as explained in 
a previous post in the ATL list, where you create a root element by hand.

> xmlns="uml2"/>

But in this Ecore model, you do not have the root element (for example, "Model"), so the 
Sample Editor doesn't propose you to create other elements.

The root element must conform to the metamodel you are trying to load, in your case, UML2.

2) another solution is try to use a set of plugins that with an user interface that helps 
to register metamodels and to create models. Instructions on how to download and install 
them are found in the post
