Here are the details:

This is how my rule looks like:

//Imports for TO and MathHelper

global com.h.MathHelper math;

rule "Coverage must equal 20% of Coverage C"

auto-focus true

agenda-group "C"

when

            Coverage information exists

            Coverage is not equal to "20" percent of Coverage C

then

            do something

end

[when]There is a Coverage with=covTO : CovTO()

[when]Coverage is not equal to "{value}" percent of Coverage A=eval(math.calculatePercentage(coveTO.getCoverage(), covTO.getD()) != "{value}")

Error: Unable to expand: Coverage is not equal to "20" percent of Coverage C[34,2]: [ERR 101] Line 34:2 no viable alternative at input 'Coverage' in rule "Coverage must equal 20% of Coverage C"[34,20]: [ERR 101] Line 34:20 no viable alternative at input 'equal' in rule "Coverage must equal 20% of Coverage C"

Thanks,

Can't help you - not enough context.
* What's the error?
* How is it used, especially preceding [when] clauses, where covTO ought to get defined

How do we get this done in Drools 5.2.1:

[when]Cov is not equal to "{value}" percent of Coverage A = eval(math.calculatePercentages(covTO.getCoverage(), covTO.getD()) != {value})

This used to compile in Drools  3.

Thanks
