Description Vladimir Riha 2014-01-03 17:25:09 UTC 
Please try following code in either JS file or embedded in HTML:

var pool = []; // purple

function makeRequests() {
    pool = []; // green
    for (var i = 0; i < numberOfRequests; i++) {
        pool[i] = i; // green
    }
}



and notice "pool" variable:
1) On line with declaration, it is purple but 2 following occurrences are green
2) Navigator shows pool twice, once in global scope, once below makeRequests function
3) if you select "purple" pool and press Ctrl+R, two following occurrences are not renamed (also "mark occurrences" ignores them). The same happens vice versa, if you try "green" pool and repeat, only 2nd green is highlighted/renamed, purple one is ignored.

It seems to be caused by the pool = [] inside makeRequests function. It is reproducible also if the entire code is inside another function

I'd vote for P2 but I don't have a string opinion (it is reproducible in 7.4 as well and no one noticed it)

Comment 1 Vladimir Riha 2014-01-03 19:25:35 UTC 
Seems like it happens just with [] array. If pool would be 

var pool = new Date()

and the same in makeRequests() it works, the same for {} or combination of both => P3
Comment 2 Petr Pisl 2014-01-16 10:37:05 UTC
