prototype.js Element.select is not side effect free

Reported by Bryan Larsen | April 20th, 2011 @ 02:02 AM

I was doing some testing of hobo-jquery and I ran across a peculiar bug.

I instrumented it with this:

            alert(formlet.find("form :input").length);
            alert(formlet.find("form :input").length);
            alert(formlet.find("form :input").length);

On a page without any forms, it returned "5" the first two times, and returned "0" on the last.

I was able to get rid of it with the attached patch, which is completely unrelated and shouldn't have an effect on anything. It probably indicates a bug in prototype, but the latest version of prototype and lowpro do not fix the problem.

(from [1c377267f73d7f33b56ab7d2df0c1d259e55dc85]) [#944] strange workaround for a bug in prototype.js. You'll need to re-run rails generate hobo:rapid in your applications to pull in this fix.

- State changed from “new” to “resolved”
Closing for now; I'm thinking the next step for this is to rewrite hobo-rapid in jQuery anyways.
