Description Vladimir Riha 2013-11-28 16:10:13 UTC 
Please try to debug this file:


var d = new Date();
var x = 1;
var y = {a: 1, b: new Date()};
var f = function() { // line breakpoint here
};


and open Variables window

=> value of "d" is undefined, but it should be expandable object (Date), tooltip shows string value of Date, but in HTML5 project, it is again expandable object

Comment 1 Vladimir Riha 2013-12-12 15:32:09 UTC 
Please notice that also "b" on line 3 has wrong (but different) value in Variables and tooltip:
 - value in Variables is {}
 - tooltip over b shows null

Comment 2 Martin Entlicher 2014-02-09 13:10:51 UTC 
The value of "d" is fixed by http://hg.netbeans.org/core-main/rev/e3c406e084af
But I do not think we can easily fix the "tooltip over b" problem.
The tooltip would have to detect somehow, that "b" is actually under "y" and evaluate it as "y.b", not "b" only.
