Do you really need to assert an Iterator into memory? this does not "sound" good to me...
If you really need, IMO you have 2 options: either create your own wrapper for the "array iterator", that is not a "final" nor "private" class, or disable shadow facts for this class only. If you need to change anything in it, make sure you do that inside a modify() block, not using update. http://blog.athico.com/2007/12/modify-block-for-java-dialect.html http://blog.athico.com/2008/02/shadow-facts-what-you-always-wanted-to.html []s Edson 2008/4/1, Narendra Valada <[EMAIL PROTECTED]>: > > Hi, > > I am upgrading to Drools 4.0.4 and I am getting this exception when > executing this rule: > > rule "insert iterator" > when > somecondition > then > insert(Arrays.asList(some array).iterator()); > end > > Here is the exception.
