Comment 1 David Williams CLA 2010-10-05 03:20:07 EDT 
This sounds familiar ... but should have been fixed by 9/30 (Helios SR1). 

This part of the build id "3.5.2.R35x" looks suspicious. You have probably updated from a Galileo release? You might spell out what you installed and how. 

Might help the team if you attached your "configuration" type data ... from the about box.
Comment 2 Nick Sandonato CLA 2010-10-05 09:14:28 EDT 
I agree with David, this sounds like the case of Helios PDT being installed on top of a Galileo base.

CSSStructuredContentAssistProcessor is a new class introduced in Helios by WTP, which is being referenced by the Helios PDT. So, if css.ui is a Galileo version, you will get this Error.

A clean install of the PDT will likely resolve this problem.
Comment 3 Nick Sandonato CLA 2010-10-11 09:06:20 EDT 
Hi Brandon,

Have you been able to research your environment to provide answers to questions posed in comment 1? Also, have you tried a clean install of Helios with SR1?

Thanks.
Comment 4 Brandon CLA 2010-10-11 10:07:53 EDT 
@ Nick - I have not messed with it.  I had started using NetBeans a little and this issue I have just been using NB.  I have noticed the performance is much faster anyhow.  From my perspective, I would consider this closed as I am not going to hassle with it in the immediate future...gotta get a new web application launched.
Comment 5 Nick Sandonato CLA 2010-10-12 17:41:25 EDT 
Brandon,

Thanks for checking back in. Are there any particular performance problems that you remember or can reproduce that we can take a look at? Feel free to open some bugs.

I'm resolving this as Not Eclipse. This is typically an issue we've seen where newer plug-ins are installed over an older base.

Thanks.
