When activating a proxy (with the Web UI), I always get following error message:
WARNING: EPRs are NULL. Transport configuration may be incorrect
But I just don’t understand why and what it means?

The source of the proxy:
<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse" name="patient_toMPI_pJMS_qPatientToMPI" statistics="disable" trace="disable" transports="jms">
<parameter name="transport.jms.Destination">patient_qPatientToMPI</parameter>
<parameter name="transport.jms.ConnectionFactory">queueNonBlocking</parameter>
<parameter name="transport.jms.DestinationType">queue</parameter>
<parameter name="transport.jms.ContentType">
<rules>
<jmsProperty>contentType</jmsProperty>
<default>application/xml</default>
</rules>
</parameter>
<target faultSequence="errorSequence">

<log level="custom">
<property name="Patient/toMPI" value="proxy (patient_toMPI_pJMS_qPatientToMPI) called"/>
</log>
<sequence key="patient_toMPI_sTransform"/>
</inSequence>
</target>
</proxy>
This has already been reported as a bug here. It will be resolved in future releases.
