Thanks Edson, however here is more info on the issue as I’ve been playing with it:

1. I have other elements in other objects referenced within the same rule group that start with capital letters and they have no problem. Example:

, FHAMaxBaseMortgageWithToleranceAmt < ($totalLoanAmt+$aggregateSubordinateFinancingAmt)

Compiles just fine in the same session.

2. If I lower the first M to m to make it mICompanyMarketClassification, it compiles in 5.2 but does NOT compile in 5.0.1

3. If I leave it as the capitalized MICompanyMarketClassification, it compiles in 5.0.1 but not 5.2

Thoughts?

Subject: Re: [rules-users] Capitalized element names

Hi Tom,

I've seen this before and AFAIK, the javaBeans spec always transforms the first letter to lowercase when converting a get method into a property name. We can try to address this in future releases, maybe falling back to uppercase if the lower case property name lookup fails, but I don't think there is a solution to keep it as is. In 5.2. you can use the full method name instead, but not sure if that isn't event worse:

MortageInsurance{ getMICompanyMarketClassification() in (“2”, “3”) }

2011/7/26 <Tom.E.Murphy@wellsfargo.com>

In the following rule, the element MICompanyMarketClassification is capitalized due to the MI portion being an acronym for Mortgage Insurance.

This comes from our enterprise data model and is not something I can change.

rule “R1234”

dialect “java”

when

MortageInsurance{ MICompanyMarketClassification in (“2”, “3”) }

then

system.out.printLn(“something”);

end

The rule refuses to compile, giving a message “Unable to Analyse Expression MICompanyMarketClassification == "2" || MICompanyMarketClassification == "3":

[Error: no such identifier: MICompanyMarketClassification]

[Near : {... MICompanyMarketClassification ....}]”

I assume this is caused by the capitalized first letter?

Anything I can do to fix the issue or work around it?
