[rules-users] Can I insert a fact from within a drl function?

[Wolfgang Laun]

insert and its cousins all depend on a context where the variable drools is
defined and supplie by the parser, and this is restricted to consequence code.

import org.drools.runtime.KnowledgeContext;

function makeFact( KnowledgeContext kContext, ... ){
    Fact f = new Fact( ... );
    kContext.getKnowledgeRuntime().insert( f );
}

then
   makeFact( kcontext, ... );
end
