com.gargoylesoftware.htmlunit.ScriptException: Exception invoking jsxFunction_getComputedStyle about akephalos

[bernerdschaefer]

Appears htmlunit doesn't like something about the javascript. I find it easiest to debug these issues by making htmlunit's logging more verbose. See #50 for being able to configure this, but for now I usually bundle open and then change:

# lib/akephalos/htmlunit.rb
java.lang.System.setProperty("org.apache.commons.logging.simplelog.defaultlog", "fatal")

to something like:

java.lang.System.setProperty("org.apache.commons.logging.simplelog.defaultlog", "debug")

The debug level produces a lot (A LOT) of noise, but can definitely help pinpoint where the issue is.

I receive the same exception when clicking on a link with a data-method="post" attribute. Switching the log-level to debug resulted in:

senny, what did you do to get around this?

Unfortunately I've stared at this output for an hour to no avail. I'm getting to errors: one in this ticket, and another https://github.com/bernerdschaefer/akephalos/issues#issue/55

I didn't have the time to debug the issue any further, I switched back to selenium...

I have the same error,

in view
link_to "more pie", @pie, :method => 'put', :class => "pie_a_lot"

in rspec
click_on('more pie')

Yeah, I'm getting this when telling capybara to click on a link issuing a POST request. It's not even a JS link. As in:

<a href="/therapy_sessions?time=1%3A00+PM" data-method="post" rel="nofollow">1:00 PM</a>

I get this error if my page tested using akephalos icludes css file that contains:
.selectbox.items li>.item{color:#000;cursor:default;display:block;padding:4px 6px;text-decoration:none;}

The problem is with child selector: li>.item

i got this issue and traced it back to a spot where jQuery was being used to modify an element that was not yet attached the DOM. something like:

jQuery("<div id='new-element'></div>").hide().etc()

which i could work around
