Test plan:
[1] Apply the example patch for a Blur action in barcode.pl.
[2] Check that barcode.pl is active in your framework and that
autoBarcode is not disabled.
[3] Open the browser dev console.
[4] Tab a few times through barcode in the neworderempty form of
Acquisition. If you leave the field, the Blur event fires.
=> Without this patch you will see two console lines (FF may
show a little '2' icon at the right side) added. With this
patch just one.
