The Grails cxf-client plugin has been updated to version 1.2.9. When I first deployed the plugin I overlooked allowing checked exceptions and soap faults to bubble out of the client proxy appropriately. I modified the plugin to allow this now. In addition I added a configuration parameter for proxyFactoryBindingId to allow soap 1.2 (set to “http://schemas.xmlsoap.org/wsdl/soap12/”).

Updated Parameter Documentation

The following partial documentation is available in full at https://github.com/Grails-Plugin-Consortium/grails-cxf-client

Property	Description	Required
proxyFactoryBindingId	The URI, or ID, of the message binding for the endpoint to use. For SOAP the binding URI(ID) is specified by the JAX-WS specification. For other message bindings the URI is the namespace of the WSDL extensions used to specify the binding. If you would like to change the binding (to use soap12 for example) set this value to “http://schemas.xmlsoap.org/wsdl/soap12/”. (default: “”)	No
