> Key: CMIS-518

> Project: Chemistry
> Issue Type: Bug

> Affects Versions: OpenCMIS 0.7.0
> Reporter: David Ward

> We came across this issue in
> https://issues.alfresco.com/jira/browse/ALF-13088 . This is affecting
> Alfresco OpenCMIS Extensions.
> It would seem that the presence or absence of xalan.jar on the sending side
> can affect the receiver's ability to lookup attributes on an extension
> element.
> The two examples given at
> http://groups.google.com/group/alfresco-opencmis-extension/browse_thread/thread/f9d9152691e5a04f
> are equivalent. They just use different ways of serializing the same
> namespaced XML.
> I think the problem lies in the way that OpenCMIS deserializes extension
> elements. It strips the namespace from all attributes, loading their local
> name into a single map. That means xmlns:propertyDefinitionId and
> propertyDefinitionId:propertyDefinitionId may be considered to be the same
> attribute so one can overwrite the other.
> The attached patch to
> org.apache.chemistry.opencmis.commons.impl.Converter.convertDomToCmisExtensionElement()
> fixed the issue for us, making it only pay attention to attributes in the
> element's namespace. What do you think?
