Groovy Error - java.lang.String exception thrown

Hi,

I'm getting a java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.String exception thrown in a groovy step.

I have a test case property which holds a count variable for use every time I loop through a template test case. My groovy step is to be used to call some custom reporting functionality.

def currentTest = context.expand( '${ReferenceData_DataSource_Request#Test_Name}' )

// read the "ReportCount" property
def count = testRunner.testCase.properties["ReportCount"].value
log.info(count)

// read all the previous test step results up to the current test step
def results = testRunner.results
log.info("Reading "+results.size()+" previous test step results...")

// loop through the results and check for falures
// if it is the first loop in the template test will start at position 0 of results, else start
// at the updated count position.
while(count if(results[count].status.toString() == "FAILED"){
break
count++
}
}

// if any of steps fails - log some error condition otherwise report test case passed
if(count log.info(currentTest+" : Failure in TestStep ["+results[count].testStep.name+"]")

for(msg in results[count].messages){
log.info(msg)
}
}
else
{
log.info(currentTest+": PASSED")
}

// set the "ReportCount" property for use in the next loop of the template test case
log.info("writing count value to ReportCount: "+results.size())
testRunner.testCase.properties["ReportCount"].value = results.size()

The folloing output is produced in the groovy log:-

The script appears to work for the first 3 loops but then throws the Exception. Anybody got any suggestions?

Cheers
