Rails spinoffs - Mar 2007 - Enumberable this._each is not a function

I''m trying to use another javascript library from ChartDirector that
lets me zoom in/out in graphs.  Their library also includes AJAX
routines to submit image map data back to the server for updated
graphs.

After I include the prototype libraries and try to zoom in/out, I get
a "this._each is not a function" in the Enumberable class. 
I''ve tried
prototype version 1.5 and 1.5.1 and get the same error.

I believe I''ve narrowed down the issue to when the
ChartDirector''s
AJAX handler tries to send an AJAX call to the web server.

Does anyone have an idea how I can make these two libraries work
together?  My first thought is around Element.addMethods.  Another
thing I''ve thought about is can you force Prototype to ignore
elements, so that I could feasibly ignore the elements that
ChartDirector is manipulating?

Also, if it helps, here is some info from Firebug:
this._each is not a function
  each(undefined)prototype.js (line 428)
  applyHandlers("preupdate")cdjcv.js (line 175)
  partialUpdate()cdjcv.js (line 177)
  applyHandlers("viewportchanged")cdjcv.js (line 175)
  l71(0, -0.002729166666666666, 0.02, -0.1384615384615384, 2)cdjcv.js
(line 170)
  lg1(mouseup clientX=0, clientY=0, 0.5)cdjcv.js (line 163)
  lv(mouseup clientX=0, clientY=0)cdjcv.js (line 161)
  onImgMouseUp(mouseup clientX=0, clientY=0)cdjcv.js (line 125)
  lr1(mouseup clientX=0, clientY=0, "MouseUp")cdjcv.js (line 50)
  onmouseup(mouseup clientX=0, clientY=0)cdjcv.js (line 52)
  [Break on this error] this._each(function(value) {



Thanks for any help,


Andrew

Hey Andrew,

I would be tempted to say they must extend some prototype (possibly 
Array?) with each as well, but in another way.  Then Prototype''s 
implementation takes over, which does require that there is a _each 
method in the object you''re calling it over.  And for some reason,
it''s
not the case just then.
