[Proto-Scripty] Re: Bug/Issue with autocompleter in IE7, first request doesn't appear, subsequent requests do
We are having this exact same problem, although it only seemed to pop
up with version 1.8.2. We have been using 1.8.1 just fine. Does
anyone else see this?

[Proto-Scripty] Re: Bug/Issue with autocompleter in IE7, first request doesn't appear, subsequent requests do
I think I found closer to the root cause of the issue. In
prototype.js I made a small change to getOffsetParent which fixed my
issue:
The line:
while ((element = element.parentNode) && element != document.body)
Becomes:
while ((element = element.parentNode) && element != document.body
&& element.style)
I'm not sure how or why, but somehow an element gets sent to this
method which does not have a style attribute. The causes the line:
if (Element.getStyle(element, 'position') != 'static')
To throw an exception. I couldn't pinpoint what had changed in
prototype to cause this behavior. We are using prototype 1.6.0.1 just
fine, but 1.6.0.3 on IE6 causes us problems here. Does anyone else
have thoughts?

[Proto-Scripty] Re: Event.observer with mouseup?
Another alternative is to use Prototype's Curry function which let's
you create new functions with default arguments.
So you could write:
Event.observe(window, 'mouseup', alert.curry('hi'));
Joe
As long as you know what curry does, I think this is more obvious for
really simple examples like this.
