Override mechanism for custom extension parser [message #408207]

Hi!

I've registered a custom extension parser for the extension '*' to
enable the extended meta data feature for my XMI resources (by setting
default save and load options).

The custom extension parser seems to override the default xmi parser
that is registered for '*' too, but I'm not sure if it is allowed to
register more than one extension factory for the same extension, because
the extension point documentation does not say anything about that issue.
(Precedence is undefined; future EMF versions may throw an exception; etc.)

Error log says:
!MESSAGE Both 'org.eclipse.emf.ecore.xmi' and 'com.dgr.profi.core'
register an extension parser for '*'

Is there a "legal" way to override the default extension parser?
Is there a better way to define default load/save options for resources?

Thanks,
Mario

Mario,

No, you can't globally register more than one parser for the same
extension. Each resource set has a local resource factory registry, so
it's better for a case like this to register you stuff local to your
application's resource set.

No. And you're bound to break something else with what you're doing, so
better not do it rather than try to make it look like everything is all
fine by disabling a warning.
