I have defined several _required_ attributes in my model, some with
default values.
When generating a diagram, if these attributes with default values are
not changed, the resulting semantic model will not include those
attributes with their default values in the element.
E.g.
Pipe 'foobar':
-name="foobar" (String)
-length=10 (Double, default=5, req.)
-diameter=1 (Double, default=1, req.)
-friction=0.35 (Double, default=0.35, req.)
the semantic model diagram xml results as this:
....
<nodes xmi:type="foo:Pipe" xmi:id="_KIzOsO3iEdujV4yBOSY8tQ"
name="foobar" length="10.0"/>
....
Needless to say, the genmodel generated XSD file gives me plenty of
"XSD: The 'use' must be 'optional' when a 'default' is present" errors
(and I understand why). Even the required attributes without default
values get a 'default=""' in the schema.
Is this all a known bug? Or perhaps there's a workaround to it? Or
maybe I'm doing something wrong?
FYI, I'm using GMFv2 M6...
Regards,
Jacob

Jacob,
The options XMLResource.OPTION_KEEP_DEFAULT_CONTENT mapped to
Boolean.TRUE is needed if you want EMF to save features for which eIsSet
is false. I can't reproduce the schema generation problem you describe
but if you can provide a test case that does reproduce that problem,
I'll be happy to have a look.

Actually found something to get rid of the default="" in schema
production. An EMF/ecore editor context menu item for Default Literal
Value which I wasn't aware of, Restore Default Value... apparently if
you just edit/delete a value you had placed in the field, it treats it
as "". This menu item removes it completely, as if it had never been
set at all.
As for the required default values, I started in with some OCL
initialization, probably best that way.
Thanks guys.
