The execute() exception probably marks the whole transaction for rollback, so your error content never gets committed to the repository.

It's better to return an error HTTP response or, if that's not practical, at least raise an error in the logs.

Thanks,

Hi Mike,

If I really want to catch an error in javascript and ignore it, is it feasible? I tried using the try/catch statement, but seems that it does not work. The script still exist with error so the content got "roll back".

There may be one or two situations when you can catch an exception in alfresco java script and ignore the error. However that is very much an edge case and could be considered a bug.

The rule when using the alfresco or Java API is that exceptions are fatal to the transaction. You may decorate the exception, by throwing another exception but you can't "ignore" one, your transaction is rolling back.
