Mule - how to get Mule to throw an exception if XML schema validation fails

I'm using a Mule schema validation filter to validate an incoming XML file against a given scheme. Below is my configuration for the schema component: `<mulexml:schema-validation-filter schemaLocations="${app.home}/classes/schemas/Library.xsd" doc:name="Schema Validation"/>` The issue I'm having is that when a file fails to validate against the schema, Mule silently blocks the message from continuing - i.e. no error/exception is thrown. Through a little experimentation I discovered that if I add the following to my log4j.properties file, I can see the 'errors' in the schema validation: `log4j.logger.org.mule.module.xml.filters.SchemaValidationFilter=DEBUG` Since these errors are 'DEBUG' level logs and no actual exception is thrown, my flow doesn't revert to the exception strategy I've configured. So the question I have is... Is there something I can do here to make Mule revert to an exception strategy if there is an error in the schema validation? I've included a copy below of the debug logs that I see when a file fails to validate. Thanks in advance. ``` DEBUG 2014-04-15 11:19:20,705 [[processes].orderInputFileConnector.receiver.01] org.mule.module.xml.filters.SchemaValidationFilter: SchemaValidationFilter rejected a message

also found the following solution which doesn't give any errors inside of Mule Studio. It involves defining the Schema Validation Filter globally and referencing it inside a message filter like so: ``` <mulexml:schema-validation-filter name="myValidator".../> <flow> <message-filter throwOnUnaccepted="true"> <filter ref="myValidator"/> </message-filter> ```
