Description Tom B CLA 2011-10-19 05:18:44 EDT 
Build Identifier: 20110218-0911

An exception with message 'a null value was used' is thrown when comparing nullable dates with null,  using the '== null' operator

Reproducible: Always

Steps to Reproduce:
1. Generate EDate001.as an EGL Test Driver (Java) file is in org.eclipse.edt.eunit.test/api.eglx_lang
2. Run the generated file EDate001_pgm.java

Testcases 3,5,6 fail with exception. Problem can be toggled by commenting out the assertTrue statement and regenerating. These testcases were copied from EString001.egl and modified to use date variables.
Comment 1 Tom B CLA 2011-10-19 05:20:31 EDT 
the dates are declared with the ? operator e.g. myDate date?
Comment 2 Jeff Douglas CLA 2011-10-21 16:04:26 EDT 
fixed

I question some of the other tests in this testcase.

For example, 
	function runAssignmentFunction02(){@Test}
		myDate date?;
		LogResult.assertTrue("nullable initialization", ((myDate != "") == false ));
	end


why would a null date be expected to be = and empty string?
