Prototype error - iterator is not a function

I''m starting to learn to use Prototype (v1.5.1.1) along with Mootools.
However I keep bumping into the same problem:

All of the inserts result in the error "iterator is not a function" at
line 542 of Prototype

memo = iterator(memo, value, index);

Am I missing something obvious here? I''m wondering if there''s
an
incompatibility between Prototype and Domino (which I''m using as the
web server)?

Does anyone have any ideas on this? I can post some of the code that
gets generated if that helps but I suspect that it''s something more
fundamental like the codepage not being what Prototype or Domino
expects.

Thanks,

Pseudonym

Javascript (and therefore Prototype) operate on the client side, so
it''s _extremely_ unlikely that an incompatibility with the web server
is causing the problem.

However, it''s hard to say what the problem is without seeing the code
that''s generating the error. I mean, I _could_ give you a generic
explanation, but it will be little more than a restatement of the
error message you''re getting.

Re: Prototype error - iterator is not a function

Thanks for your response. I''ve actually managed to prove on a test
server that the fact that Domino doesn''t use UTF-8 by default
isn''t
the root cause. This is an attempt to mimic the code sample at
http://demos.mootools.net/Fx.Slide however I get the same error at the
same line with several other tests. Prototype and mootools
scriptlibraries are the latest non-beta downloads from their
respective websites.

Re: Prototype error - iterator is not a function

Hi,

I would suggest you used Prototype 1.6 (which has been released
minutes ago) instead of 1.5.1.1.

Secondly, I very much doubt that you can use both mootools and
Prototype on the same page, as both of them cover really similar
ground.

I would suggest going with either one of those two libs.

Regards,

Tobie

Re: Prototype error - iterator is not a function

Got it working now:

var slide_misc = new Fx.Slide(''divmisc'');

should be

var mySlide = new Fx.Slide(''divmisc'');

There were a few other things I had wrong as well.

Re: Prototype error - iterator is not a function

Mootools once began as an effects library (moofx) for prototype, much
like scriptaculous, but they discontinued support for prototype when
they created their own javascript library.

A lot of the modules and methods in mootools are ''inspired''
from
prototype (amongst others), so i is likely they will clash when used
together on a page... Though it is safe to use the mootools effects
library (moofx) as prototype doesn''t venture in that area of
javascript.
>From my own experience I found out that although you can download aspecial prototype version of moofx (http://moofx.mad4milk.net/
#prototype) it is far from bug-free.
