Yes, it is possible to specify a specific version of asset in changeset. though this is not supported by Change-set editor at the moment, you have to edit the content of change-set xml file manually. For example, below is generated by change-set editor: <change-set xmlns='http://drools.org/drools-5.0/change-set' xmlns:xs='http://www.w3.org/2001/XMLSchema-instance' xs:schemaLocation='http://drools.org/drools-5.0/change-set http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-api/src/... > <add> <resource source='http://localhost:8080/drools-guvnor/rest/packages/defaultPackage/assets/sss/source' type='DRL' /> </add> </change-set> If you want to use a specific version of asset "sss", what you need to do is to modify the source URL, make it pointing to the specific version of the asset source. eg: <resource source='http://localhost:8080/drools-guvnor/rest/packages/defaultPackage/assets/sss/versions/2/source' type='DRL' /> This is to get version 2 of asset "sss" source.
