[rules-users] rule validates in guvnor but errors when running

[kurrent93]

Hi

I'm trying to understand what is wrong with this rule. It validates in
guvnor, but when running it throws an error.

I am trying to write a rule that will fire if there have been less than ten
trades in ten minutes.

This is the rule:
1.	|	rule "Trade Count"
2.	|	    dialect "mvel"
3.	|	    when
4.	|	        Number( trades : intValue < 10 )
5.	|	         from accumulate(
6.	|	         e: TradeOrder( )
7.	|	         over window:size(10m),
8.	|	         count(e) )
9.	|	    then
10.	|	        TradeOrder silverTrade = new TradeOrder();
11.	|	        silverTrade.setMt4username( "4002642" );
12.	|	        silverTrade.setOperation( "OP_BUY" );
13.	|	        silverTrade.setStatus( OrderStatus.OPENING );
14.	|	        silverTrade.setSymbol( "SILVER" );
15.	|	        silverTrade.setVolume( 1 );
16.	|	        silverTrade.setOrderLots( 2 );
17.	|	        insert( silverTrade );
18.	|	        
19.	|	        
20.	|	        modifiedOrderList.add(silverTrade);
21.	|	end

What I assume to be the relevant portion of the stack trace is here:
