What happens when you set the variable = undefined? I would have expected this to work.
If you delete a variable: delete myVar; then try to access it, it returns undefined. Maybe you could use that behavior.

This question is about Flex 1.5. My app passes some String vars thru the Flex gateway to Java. When the var = undefined on the Flex side, it translates to null on the java side, which is great. When the var = "" (null String) on the flex side, it translates to a String("") on the java side, which ain't null. I would like to check for "" on the Flex side and convert those values to something that translates thru the gateway as a null object, but so far I can't get it to happen. Values are only undefined before they are used; once used and cleared out, they become "" and can evidently never be set back to undefined again. So my actual question is, what can I set the object to be that will translate as null going thru the gateway? I have tried: setting them to undefined; setting myVar = null; setting myVar = x (an undefined variable); several other combinations.
