[rules-users] Cryptic error message: org.drools.compiler.FunctionError at 191394e

[Scott Reed]

I found the error by commenting out all the code and carefully uncommenting bits of it until the 
error occurred again.

It turned out to be a function in the DRL that called Knowledgehelper.clearAgenda(). From reading 
the Javadocs I assume this has been replaced by Workingmemory.clearAgenda(). With that change the 
DRL compiled OK. I hate to whine, but couldn't we have deprecated the old method instead of just 
removing it?

1)I would really appreciate it if someone could point me to a list of all the API changes that have 
been made.

2)Is the plugin supposed to be working as it is, not telling me where there are errors?
