Hello,
i have an Object with two multi-valued attributes. One of these
attributes is editable over a gmf editor. the other attribute is
effected programmatically. When i save the object, there is only the
first attribute saved. The second is not in the xmi representation. Why
is that?
Thanks for your help

Jörg,
I see. Only an XMIResourceImpl will save multiple root objects, because
it serializes a "fake" XMI root elememt. An XMLResourceImpl will only
save a single root object, so you'd need to define a class whose
instances can hold multiple objects and use one of those as the root.

Hello,
hmm multiple roots would be okay, i need the correct childrentree. but
in the xml representation he has now one root with no childs. The
rootelement has children in a contained elist. How can i get them into
the resource. the add method ignores now the none root elements.
Thanks
Jörg

Jörg,
Keep in mind that generally adding a child to the contents of a resource
will remove it from the parent. So perhaps you need to be more careful
that if eContainer() != null and if eResource() != null that you don't
try to add that object to the root of a resource because it's already
indirectly contained by a resource.
