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

It seems I am unable to insert a new fact from within a drl function. I tried this: //////////////////////// package com.sample declare Dummy end function void init() { insert(new Dummy()); // Doesn't compile } rule "init" salience 999 when then init(); insert(new Dummy()); // Compiles end //////////////////////// Is the above supposed to work?
