hi, looks like your data comes as a primitive int, hence the type cast exception. On 17/05/2011 09:42, Giorgio Spagnardi wrote: -- Greg Stasica PaceMetrics Ltd.

Really, it's not my code so I don't know way :( and looking for $cm, I found it seems to be already an int!

And this just can't be cast to java.lang.Integer. There are several ways for creating an Integer from an int, but why do you do the cast at all? -W On 17 May 2011 10:42, Giorgio Spagnardi <g.spagnardi@reply.it<mailto:g.spagnardi@reply.it>> wrote: Hi to all, I used the business rule guided editor to write a new rule.
