Running multiple projects load tests sequentially

I've tried the following

def fcdcc =
context.LoadTestRunner.LoadTest.testSuite.project.getTestSuiteByName('MyTestSuite').getLoadTestByName('MyLoadTest')
		def properties = new com.eviware.soapui.support.types.StringToObjectMap ()
		def async = false
		fcdcc.run (properties, async)

 but it errors
