Can't seem to access Arrays which are initialized in a constructor

[Lewis Flanagan]

Hey, I've run into a problem with my project. I can't seem to access Arrays which are initialized in a constructor. Here's a simple class that

illustrates the problem.

public class ArrayTest 

{

val classFieldArray: Array[Int];

val classFieldArray2 = new Array[Int] (10, 0);

def this ()

{

classFieldArray = new Array[Int] (10, 0);

}

public def isFine ()

{

val localArray = new Array[Int] (10, 0);

localArray(2) = 5;

}

public def isAlsoFine ()

{

classFieldArray2(2) = 5;

}

public def wontCompile ()

{

classFieldArray(2) = 5;

/*Cannot assign expression to array element of given type.

Expression: 5

Type: x10.lang.Int{self==5}

Array element: ArrayTest.this.classFieldArray(2)

Type: x10.lang.Int

Cause: Method apply(i0: x10.lang.Int){x10.array.Array#this.region.rank==1}[]

in x10.array.Array[x10.lang.Int]{self==ArrayTest#this.classFieldArray,

ArrayTest#this.classFieldArray.region!=null} cannot be called with arguments

(x10.lang.Int{self==2}); Call invalid; calling environment does not entail

the method guard. */

}

}

the methods isFine () and isAlsoFine, compile fine. The method wontCompile, won't compile. The error message eclipse gives is the comment below it. I download the version of x10 I'm using just before break so it should be the most recent version. Can anyone tell me why this is happening? I'd be appreciative.

Instead of:

val classFieldArray: Array[Int];

Write:

val classFieldArray: Array[Int](1);

That will tell the compiler you are using 1-dimensional arrays.

Thank you!
