Colin,
First - Very cool plugin idea :>
Can you look at the revised plugin example for that blog post here:
http://www.birt-exchange.org/devshare/designing-birt-reports /1101-example-plugin-for-expression-builder/#description
It was modified to work with 2.5.1. Can you verify that it works
deployed for you? If you can send me your plugin in email I can try to
debug it. Note that the arguments for execute have been extended:
public Object execute( Object[] args, IScriptFunctionContext arg1 )
throws BirtException
Also verify you have no dependencies on any ui plugin.
