I have a lot of the the latest bits from Helios loaded. Running on Ubuntu Linux. I'm presented with an error dialog every time I hit save. Here's the corresponding log entry. -- Error Details -- Date: Tue Jun 29 17:15:27 EDT 2010 Message: Errors running builder 'JavaScript Validator' on project 'www'.

My mistake. It happens on every workspace build. I had to remove the validation builder from the project to be able to get anything done. I'll try to run the workspace in debug sometime tomorrow to see if I can identify the what code it's stumbling over.
Do you have any sample source that reproduces this problem?
From what I can tell, one of the YUI JS files that's causing trouble. I haven't had sufficient time to really understand what the code is doing, but the MethodDeclaration(AbstractMethodDeclaration).resolve(Scope) has the following value for "upperScope" --- JavaScriptUnit Scope : /www/eclipse.org-common/yui/2.6.0/build/profilerviewer/profilerviewer-beta.js You can obtain this file from the eclipse.org site: http://www.eclipse.org/eclipse.org-common/yui/2.6.0/build/profilerviewer/profilerviewer-beta.js I'll try to repeat this in a clean workspace.
Ah. No joy initially. But I think I have an isolated example. 1) Create a new workspace 2) Create a new JavaScript project. 3) Drop http://www.eclipse.org/eclipse.org-common/yui/2.6.0/build/profilerviewer/profilerviewer-beta.js and http://www.eclipse.org/eclipse.org-common/yui/2.6.0/build/dragdrop/dragdrop.js into the project 4) Error occurs The error did not occur initially with only the profileviewer-beta.js script in the project. It occurred immediately after adding the dragdrop.js script (thereby invoking the build). The problem disappears when I remove the profileviewer-beta.js script. It then reappears if I re-add the file. If I'm reading the stack trace correctly (which isn't guaranteed), I believe that it's line 698 in profilerviewer-beta.js that's causing the problem: -- resizeable: (YAHOO.util.DragDrop) ? true : false, -- HTH. I can attach my workspace if you think that's valuable.
Error no longer occurs in 3.2.1.
