Strange behaviour when running parameterized test

Hello,

I am using Flex 4.5 and FlexUnit 4.1 inside of the Flashdevelop IDE and I am experiencing some very strange behaviour.

If I have 5 parameters to my test the test runs fine. When I add a sixth parameter of the type Array, I get the following error:

"TypeError: Error #1009: Cannot access a property or method of a null object reference."

Please see below for my example code.

The following parameterized test case runs without a problem:

package {

import org.flexunit.runners.Parameterized;

[RunWith('org.flexunit.runners.Parameterized')]

public class ParameterizedTest {

[Parameters]

public static var testData:Array = [

[1,1,new Array(),1,1]

];

public function ParameterizedTest(

param1:uint,

param2:uint,

param3:Array,

param4:uint,

param5:uint

):void {

}

[Test]

public function testOne():void {

// Test to go here.

}

When I add an Array as the sixth parameter :

package {

import org.flexunit.runners.Parameterized;

[RunWith('org.flexunit.runners.Parameterized')]

public class ParameterizedTest {

[Parameters]

public static var testData:Array = [

[1,1,new Array(),1,1,new Array()]

];

public function ParameterizedTest(

param1:uint,

param2:uint,

param3:Array,

param4:uint,

param5:uint,

param6:Array

):void {

}

[Test]

public function testOne():void {

// Test to go here.

}

I get this error :

com.berog.proj_drum_machine.tests.matrix_test_suite.test_cases::MatrixConstructorTest.test One (1,1,,1,1,) .

TypeError: Error #1009: Cannot access a property or method of a null object reference.
