Status/Resolution/Reason: Closed/Fixed/

Reporter/Name(from Bugbase): Raymond Camden / Raymond Camden (Raymond Camden)

Created: 09/04/2014

Components: Language

Versions: 11.0

Failure Type:

Found In Build/Fixed In Build: CF11_Final /

Priority/Frequency: Major / All users will encounter

Locale/System: English / Mac 10 All

Vote Count: 8

Listed in the version 11.0.03.292480 Issues Fixed doc 
Consider this example:

<cfscript>
	
	function getfoo() {
		writeoutput("do you see me?");
		return "foo";	
	}
	
	username = encodeForHTML(url.name) ?: "Anonymous";
	writeOutput(username);
	
	u2 = encodeForHTML(url.name) ?: getfoo();
</cfscript>


If url.name exists, then getfoo() should not execute, but it does.

Both Railo/Groovy handle the RHS side correctly.

Should function in line with the languages that inspired this feature, namely Groovy.

Do not try and bend the spoon. That's impossible. Instead, only realize the truth... THERE IS NO SPOON. Then you will see that it not the spoon that bends, it is yourself.

Actually, there is a regression in CF11 Update 3. <cfscript> //foo = "A"; writeOutput(foo ?: "B"); </cfscript> 11,0,0,289822: Returns "A" when foo exists, otherwise returns "B" 11,0,03,292024(PreRelease): Returns "A" when foo exists, otherwise returns lowercase "b" In possiblyNullValue?:valueIfNull, valueIfNull is now returned as lowercase. Thanks!, -Aaron
