Hello,

I'm trying to add a custom SAMLObjectContentReference to my signature.  Here is the code I am using to generate the content reference:

SAMLObjectContentReference contentReference = new SAMLObjectContentReference(assertion);

contentReference.setDigestAlgorithm(SignatureConstants.ALGO_ID_DIGEST_SHA1);

contentReference.getTransforms().add(SignatureConstants.TRANSFORM_ENVELOPED_SIGNATURE);

contentReference.getTransforms().add(SignatureConstants.TRANSFORM_C14N_EXCL_OMIT_COMMENTS); 

signature.getContentReferences().add(contentReference);

When I run this code, the following error occurs when marshalling the assertion:

java.lang.ArrayIndexOutOfBoundsException: 3

at org.apache.xml.security.transforms.Transforms.item(Unknown Source)

at org.opensaml.common.impl.SAMLObjectContentReference.createReference(SAMLObjectContentReference.java:143)

at org.opensaml.xml.signature.impl.SignatureMarshaller.createSignatureElement(SignatureMarshaller.java:114)

at org.opensaml.xml.signature.impl.SignatureMarshaller.marshall(SignatureMarshaller.java:69)

at org.opensaml.xml.io.AbstractXMLObjectMarshaller.marshallChildElements(AbstractXMLObjectMarshaller.java:316)

at org.opensaml.xml.io.AbstractXMLObjectMarshaller.marshallInto(AbstractXMLObjectMarshaller.java:224)

at org.opensaml.xml.io.AbstractXMLObjectMarshaller.marshall(AbstractXMLObjectMarshaller.java:130)

at org.opensaml.xml.io.AbstractXMLObjectMarshaller.marshall(AbstractXMLObjectMarshaller.java:86)

There should only be 2 transforms, where is it getting the index of 3?

Thanks,

Jason
