From Drools 5.2.0, you probably don't need to use eval(callMyFunction()) any more, you can just write it without eval(): callMyFunction()
Be careful with calling custom functions though (especially those that contain loops): if you break delta score evaluation, the performance (and therefore quality of the result) will suffer greatly. Do a "stepLimit" benchmark (see class *BenchmarkApp) to verify your score rules stay fast with and without that extra rule. Also note that you can use inference: rule A salience 1 // optional when Item for SaleOrder in Box then insertLogical of a SaleOrder-Box combination end rule B when accummulate count of (SaleOrder-Box combination) // notice that is depends on rule A having run first then insertLogical of SOFT of minus count end Op 19-08-11 15:06, JimK schreef: > My question is pretty much a duh! on my part, wasn't thinking about all the > syntax options in DRL.
