JMSTestStep Assertion List

Hello,

I have started to use the JMS Test Step rather than a Soap Request to send and receive JMS messages.

I also use a number of assertions for which I would like to pull a report at the end using Groovy with the list of assertions along with its status.

I have been able to do this for all other steps using something along the lines of:

if ( testStep instanceof com.eviware.soapui.impl.wsdl.teststeps.WsdlTestRequestStep  ||
testStep instanceof com.eviware.soapui.impl.wsdl.teststeps.JdbcRequestTestStep ||
testStep instanceof com.eviware.soapui.impl.wsdl.teststeps.AssertionTestStep )


for ( assertion in testStep.assertionList )
                    {
                        assertionStatus = assertion.status as String
                    }

...which has worked exactly how I want it to.

However, when I try adding:

testStep instanceof com.eviware.soapui.impl.wsdl.teststeps.JMSTestStep 

I receive the following error:

groovy.lang.MissingPropertyException: No such property: assertionList for class: com.eviware.soapui.impl.wsdl.teststeps.JMSTestStep error

I cannot find any documentation on the soapui api docs to help me with this issue. Has anyone else attempted anything similar?
