[rules-users] Drools 5 Accumulate Function

[Steven Williams]

Hi all,

I am converting over to Drools 5 and have run into a problem with
AccumulateFunction. I changed my classes to implement
org.drools.runtime.rule.AccumulateFunction however this causes the
ClassCastException below:

Caused by: java.lang.ClassCastException:
au.com.promedicus.rules.MaxPriceAccumulateFunction cannot be cast to
org.drools.base.accumulators.AccumulateFunction
    at
org.drools.compiler.PackageBuilderConfiguration.getAccumulateFunction(PackageBuilderConfiguration.java:489)
    at
org.drools.rule.builder.dialect.java.JavaAccumulateBuilder.build(JavaAccumulateBuilder.java:108)
    ...

My guess is this is a bug. For now I will just go back to implementing
org.drools.base.accumulators.AccumulateFunction.

cheers
Steve
