Build Identifier: 0.7.0.v201110100901

In an RUI project (should have reference to RUI & Dojo widget library), import the attached H2.egl, you will see the exception when preview it in the external browser - egl.eglx.lang.TypeCastException is not a constructor.

The data grid is a very widely used widgets. I set the severity to critical, it should be resolved as soon as possible.

Reproducible: Always

The sample EGL file.
Comment 2 Brian Svihovec CLA 2011-10-11 09:46:41 EDT 
As far as I can tell, it is not possible to assign a record[] to an any[] in JavaScript:

        recordArr recordName[] = new recordName[];
    	record1 recordName = new recordName;
    	record1.field1 = "aaaa";
    	record1.field2 = "aaaa";
    	recordArr.appendElement(record1);
    	var1 any[] = recordArr as any[];

This gives the same exception, but does not involve the usage of DataGrid.

It does not seem that there is a workaround, so I am setting this to Blocker, since it means that DataGrid is unusable.

Hi Scott,
I commit the temporary fix to get over this issue.
The change only affects ArrayType conversion to any ArrayType, I guess the fix won't affect other parts.
You may want to review it and make some changes later when you're back from vacation.
Thanks.
