Description Libor Zoubek 2012-08-23 09:36:59 UTC 
Description of problem: If I try to convert instance of java.lang.Boolean class to javascript Boolean type I am getting invalid value, see example:

var my = java.lang.Boolean.FALSE;

var myjs = Boolean(my);
myjs; // is TRUE!!!

Comment 1 Lukas Krejci 2012-08-24 08:00:03 UTC 
This is a consequence of javascript's rules of Boolean conversion - http://www.w3schools.com/js/js_obj_boolean.asp.

Because the variable "my" is an object (not a raw boolean value) and it is not null, javascript initializes the myjs variable to true, just as it should according to the rules outlined in the above link.

I think this works as expected, even though it is confusing.

If you had:

var my = java.lang.Boolean.FALSE.booleanValue();

the rest of the code would have worked as expected.
