Issue seen in QT creator 4.9
if a js function has multiple arguments, when saving the file the separating comma is ommited and args concatenated. eg
function myFunction(myVal1, myVal2)...
when saving it becomes :
if the qml file is edited and saved in external editor, reloads ok - occurs only when saving file from within QT Creator.
If the QtQuick/QML/JS Editing "enable autoformat on file save" option is deselected saves ok.
