Drools error with IKVM -

-

we using drools engine on our client written in c#. using ikvm convert drools jar , our java beans dll's using ikvm. rule similar this:-

rule "aggregate rule"     when          $b : bill(billamount > 100)         $n : number(doublevalue > 100) accumulate ( $l : lineitem() $b.finditems("color", "blue"), sum($l.getsellingvalue()))             voucherseries fact0 = new voucherseries();         fact0.setseriescode( "aggregate voucher" );         insert(fact0 );         voucherlist.add(fact0);         system.out.println("sum" + $n); end

this rule works fine when run java based drools api's, while running ikvm converted drools, throws following error:-

unable cast object of type 'accumulatememory' type 'frommemory'.

any ideas on might going wrong ?

this can have many causes. example classloading problem. can bug in ikvm. etc.

i think not receive helpful answer here. should contact mailing list ikvm many details ikvm version, how have compiled dlls, runnable sample demonstrate problem.

this problem can solve if debug it.
