Error inside PhantomJS when using trigger(:hover)

[Dreyfuzz]

Not sure if this goes here or with PhantomJS, but here's what I got trying to hover

Failure/Error: page.find('#sign_in').trigger(:hover)
     Capybara::Poltergeist::BrowserError:
       There was an error inside the PhantomJS portion of Poltergeist. This is probably a bug, so please report it.

Same thing when trigger('change'). Is click the only supported event or is there a doc page for supported events?

[StuBez]

We're also experiencing problems when trying to use trigger('change'). I tried to find a page of supported events but haven't managed so far. Is there such a thing?

same experience with poltergeist 1.4.1:

Failure/Error: find(:css, '.listitem').trigger(:hover)

Should be closed, as in commit 6c52e69 . find(:css, '.listitem').hover works well.

same thing for page.find("#element").trigger(:keyup)

Found this issue because I tried to use find('#element').trigger('keyup-change') and also got the Unknown event error.
Isn't it possible to just pass the events that get passed to trigger on to the element, as it is an arbitrary string anyway? This way it would not be necessary to define every single event explicitly in the code.

+1 - trigger('change') is throwing this error for me with phantomjs 1.9.0

[mikekellyio]

As an update, I was able to work around this by manually triggering the blur event.

find("select").trigger("blur")

[asiniy]

Same error there

[johanngomes]

Same error here, using trigger("change")
