It seems that node.js support adds the same file-change listener twice.
Reassigning to javascript/Node.js. Petr, please evaluate. Thank you.

Note: May by related to bug 249908?

Comment 3 Tomas Mysik 2015-02-06 14:21:57 UTC

Taking over.

Comment 4 Tomas Mysik 2015-02-23 09:48:00 UTC

I guess a duplicate of issue #250255 - projectOpened/projectClosed not called the same number of times.

Please evaluate, thanks.
