Grep scripting bug?

[Marco_Lugli]

The following grep search works fine from within Indesign (finds all prices that don't have the "€" symbol at the end):  ((\d+)?(\.?))+(\d{1,3}),(-)?(\d+)?(?!(.*)?(€))  If I try to translate the same search expression into a script, it doesn't work anymore:  ((\\d+)?(\\.?))+(\\d{1,3}),(-)?(\\d+)?(?!(.*)?(€))  How could this be possible? Am I doing something wrong or is it a bug of the software?  Any suggestions would be much appreciated  Thanks in advance

app.findGrepPreferences=app.changeGrepPreferences=null;

app.findGrepPreferences.findWhat="((\\d+)?(\\.?))+(\\d{1,3}),(-)?(\\d+)?(?!(.*)?(€))";

toFind = app.activeDocument.findGrep();

alert(toFind.length)
