Description Vladimir Riha 2013-11-27 09:33:03 UTC 
Please try to create new Java project, add JS file with following content:

function test(){
    var a =1;
   return 3; // line breakpoint here
}

test();


 - add line breakpoint 
 - debug file
 - when debugging is paused, hover over "a"

=> tooltip says

"a = >Missing scope<"

Comment 1 Vladimir Riha 2013-11-27 09:42:01 UTC 
It seems like tooltips in general are showing wrong information:

 - Tooltip shows #NUMBER for "global" variables


var a = 1;
function test(){
   
   return a;
}

var b = test();

var c = 1; // line breakpoint here

=> tooltip for b and a shows e.g. #1325 as value of "a"



================================


var a = 1;
function test(){
   var ale = 1;
   return a; // line breakpoint here
}

var b = test();

var c = 1;


=> tooltip says value of "ale" is null



In all cases, Variables window shows correct data
Comment 2 Martin Entlicher 2013-11-27 12:31:26 UTC 
This was already partly fixed by http://hg.netbeans.org/main-silver/rev/15b40f9e6641 but some cases still remain...
Comment 3 Vladimir Riha 2013-11-27 17:03:52 UTC 
Martine, will the fix also cover similar issue with Evaluate expression (should it be supported in this debugging)? Right now it seems to evaluate similarly wrong value as the tooltip.

another case

To be thorough, another case. Add breakpoint to line 19 ("this.name = name") and debug file
 -> once debugger stops on the line, hover over "name" in line 17
=> tooltip shows "name = null"
