Array.prototype.call definition breaks jQuery 1.2.6 (OK in 1.2.3)

Reported by: geary Owned by: flesler
Priority: major Milestone: 1.3
Component: core Version: 1.2.6

Blocked by: Blocking:


If a program defines an Array.prototype.call() method, the makeArray() function in jQuery 1.2.6 becomes confused and handles arrays incorrectly. This is because of the array.call test in makeArray().

script.aculo.us effects.js v1.7.1_beta3 defines such a method and breaks jQuery. effects.js v1.8.1 no longer defines this method, so the practical impact of this conflict may be small, except for people who are using the older version of effects.js.

This conflict is the cause of the problem reported in this thread:


The fix is not immediately obvious to me, but I posted a couple of simplified test cases for 1.2.3 and 1.2.6 here:

You can fix this issue by just upgrading to Scriptaculous 1.8.x.

So I see no point on hacking our code for this.
