JS Errors in TreePanel with anim:true and Prototype adapter

[neongrau]

when you try to expand/collapse a node you'll get an infinite loop generating this error

this.transforms has no properties
[Break on this error] this.transforms.each(function(transform){
effects.js (line 982)


or is there a specific prototype version needed? i currently have the default one from rails 1.2

I had the same problem under different circumstances (when I called highlight on an element).

To fix it, I downloaded scriptaculous directly from the site (http://script.aculo.us/downloads) and unpacked it into the public folder.

Then, instead of the usual:


<%= javascript_include_tag :defaults %>

I did:


<%= stylesheet_link_tag "/ext-1.0/resources/css/ext-all.css" %>
<%= javascript_include_tag "prototype" %>
<%= javascript_include_tag "/scriptaculous-js-1.7.0/src/scriptaculous.js?load=effects" %>
<%= javascript_include_tag "/ext-1.0/adapter/prototype/ext-prototype-adapter.js" %>
<%= javascript_include_tag "/ext-1.0/ext-all-debug.js" %>

The ext-prototype-adapter seems to play nicer with the vanilla scriptaculous rather than the one packaged with Rails.

Hope that helps!

good to know, thanks!

I was getting a similar error message (this.transforms has no properties) using FX on a toolbar. When I swapped out what I think was the official scriptaculous downloaded files (not the ones that came with Rails) with the prototype and scriptaculous files from the Ext distro, it all worked fine. (Ext 1.1)
