Hi all, This question might make me look like a bit of a moaner. Then again, you shouldn't be a member of an internet forum if you'd worry about what other people think of you. Therefore: If you declare a type in one of your rule files, and use that type in another drl file, Eclipse will return an error message claiming that the type in question does not exist. And actually, he is quite right, as the type will only start existing when the kbase is created. So, the rules you created *will* work at runtime (provided you did not commit any other foolishness). The thing is, these errors are a bit annoying. Is there any way to circumvent this, moan-moan ? Or is the only way to get rid of the error messages to create the objects in java? Thanks a lot.
