Description Jiri Locker 2013-08-20 07:08:51 EDT
Description of problem:
I want to use a custom accumulate function in a rule like this:
  Number( intValue >= 100 ) from accumulate ( p : Person( sex == "M" ), mysum(p.age))

I have commited a properties file registering my implementation of accumulate function like this:

Despite of that, when I validate the rule, I'm getting an error:
Unknown accumulate function: 'mysum' on rule 'my rule'. All accumulate functions must be registered before building a resource.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:

Actual results:
Doesn't work.

Expected results:
Should be possible to register a custom accumulate function. Either using a properties file as it used to work in BRMS 5.x, or using some other project-level configuration file, ideally through Workbench UI (Project Editor perhaps?).

Additional info:

Drools Workbench (aka Guvnor) has never had explicit support for custom accumulate functions; that said, I've never tried with 5.x. Can you confirm custom accumulate functions work outside of the web application, i.e. plain DRL.

Setting priority to low as this is a nice to have feature, but the focus atm is on fixing bugs.
