OpenSAML user discussion

Good Morning Everybody,

I have recently written a SAML extension using opensaml. It works nice
and fine. However recently I realized extension that it creates has
md:Extensions not saml2P:Extensions.
I thought  default buildObject method ExtensionBuilder is creating
md:Extensions.

I did following:
1)

ExtensionsBuilder extBuilder = new ExtensionsBuilder();
                
Extensions extensions =
extBuilder.buildObject(SAMLConstants.SAML20_NS, Extensions.LOCAL_NAME,
SAMLConstants.SAML20_PREFIX);

It builds the object but when marshaling it it gives:

java.lang.ClassCastException:
org.opensaml.saml2.common.impl.ExtensionsImpl cannot be cast to
org.opensaml.xml.schema.XSAny

I see my self registering all custom object using

org.opensaml.DefaultBootstrap.bootstrap()
Configuration.registerObjectProvider(.........)

Just to try my another way:

2)
 But it does not build extBuilder.

QName extQName = new QName(SAMLConstants.SAML20_NS,
Extensions.LOCAL_NAME, SAMLConstants.SAML20_PREFIX);
ExtensionsBuilder extBuilder =
(ExtensionsBuilder)builderFactory.getBuilder(extQName);
Extensions extensions =
extBuilder.buildObject(SAMLConstants.SAML20_NS, Extensions.LOCAL_NAME,
SAMLConstants.SAML20_PREFIX);

I believe i am missing something based on the fact that everything
runs when I just use default (i.e md:Extension).

Any insight will be highly appreciated.

Thank you.
