Transition hook criteria from not respecting empty string

[christopherthielen]

I want to trigger a transition hook which only fires if the user enters a specific state without having a from state, e.g. they land on the page by typing in the URL or following a direct link.

I assumed this would be accomplished via:

$transitionsProvider.onBefore({
    from: '',
    to: 'welcome.*',
  }, transition => { ... });

However, that seems to capture any transition to any welcome.* route, as I suspect the empty from value is being ignored.

Is there another way to have hook criteria match only when there isn't any from state?
If not, can it be implemented so that an empty string (as opposed to undefined / null) triggers this check?

The docs don't document this use case either.

Agree this is a bug.

@adamreisnz I'm unable to reproduce this in angular-ui-router 1.0.0-alpha.1 through 1.0.0-rc.1

Can you please check?

Closing because I cannot reproduce. Reopen if you can reproduce.

Think it might be working now
