Bug 345720

Description Dusan Smolnikar 2011-05-13 07:44:50 EDT

Build Identifier: M20110210-1200

In js.browserWindow file, setTimeout function is defined:
/**
 * function setTimeout(arg1, arg2) 
 * @param {Object} arg1
 * @param {Number} arg2
 * @memberOf  Window
 * @returns {Object}
 */
Window.prototype.setTimeout=function(arg1, arg2){return new Object();};

However, the return type of setTimeout function is a number, as seen using the test code:
var test = window.setTimeout(function(){}, 1); alert(typeof test);
Tested on Firefox 4, Safari 5 and Opera 11.

Reproducible: Always

Steps to Reproduce:
In eclipse preferences go to:
JavaScript > Validator > Error/Warnings
and enable JavaScript semantic validation.

Now in a javascript file, enter the following code:

var test = { to : -1 };
test.to = window.setTimeout(function(){}, 1);

Second line now throws a warning:
cannot convert from Object to Number
