Description fahua jin CLA 2011-11-07 01:22:33 EST 
Build Identifier: 0.7.0.v201111060901

I have following statements in the EGL program, the returned type of function daysDifferent is int. But our EGL compiler does not prompt any error information. If generate the code to Java, then the Java program has error compilation message; If generate the code to JavaScript, then it prints true.

        amon date = "01/01/2011";
        curDate date;
        if(amon.daysDifferent(curDate))
            syslib.writeStdout("true");
        else
            syslib.writeStdout("false");
        end

Reproducible: Always

I have updated the following validators to prevent this:

CaseStatementValidator
IfStatementValidator
WhileStatementValidator

Paul,

Is there a .egl file in our system types that would indicate the lack of support for this conversion?
Comment 4 Paul Harmon CLA 2011-11-07 09:06:18 EST 
You can look at EBoolean.egl (which does not contain any conversion operations), and EInt.egl, which does not contain any conversion operation that takes an EBoolean.
