Thanks, that does stop a newline from appearing (I still only get half a star, but I'm not bothered about that!). However, without setting LANG any xterm windows still cause newlines. I understand this isn't Arcanist's fault, so feel free to close the task.

Apologies, the rule does seem to trigger. I hadn't noticed the "Rules that Affected Me" vs "Rules I Own" in the Herals rule test. It doesn't seem to be aware I'm a user of the selected project, but this isn't technically wrong.

Great! Have you been able to reproduce the Audit action causing the trigger to fail?

Another twist, the list IS produced for projects, just not users. Perhaps this is intentional?

IE+FF both fail to produce the drop down, though both do produce it on the other actions, e.g. send an email. Thanks for the project tip!

Having said that, there is another bug: Though I can create an email rule just fine, selecting "Trigger an audit by" does not allow me to select a user: Typing a name does not bring down the typical list of matched names and leaving the field blank is equivalent to the "Do Nothing" choice.

Thanks for the help!

Can confirm rule creation works fine using Firefox. Error I'm seeing appears in IE 8.0 but doesnt seem to throw a JS error, though this may just be my unfamiliarity with the IE tools. Happy for bug to be closed as IE's fault.

The issue still appears when selecting New rule for "Commits" rather than "Commit Hook: Commit Content". Looking to open an audit on commits which have not passed through Phabricator, which the commit hooks do not have as an option.
