Thank you, Holger. I'll explore the options. As always, I appreciate the
prompt response.

I narrowed it down specifically to the instance variable declarations. If I 
simply add these declarations and nothing else, I get the error. I'm adding 
instance variables using the common approach:

   MyClass extend [

        ...   "Various selectors added for extension"

How can we figure out why this error occurs? I can try to put together a very 
minimal Seaside app to reproduce it in that context if needed.
I am afraid it is a known issue. When using gst-remote (the scripts/
the Smalltalk In Smalltalk (STinST) parser is being used to parse your extension
and it doesn’t seem to handle instance variables.

With my time constraints I just maned to switch the order, load my code before
gst-remote is being used. :(

The STInST package is in packages/stinst/parser and based on the refactory
browser. With the there are some examples. I used VisualGST in
the past to debug it but then renamed the namespace so I would use a different
parser than VisualGST is using itself. There are also some testcases that could
be serve as an example.
