[rules-users] FW: Capitalized element names

[Wolfgang Laun]

Edson,

please also not JBRULES-3147: Regression: all uppercase field reference
results in compile error. Some forms used to work in 5.1.1 that don't in
5.2.

I've added the gist of this thread to JIRA-3147.

>    If one works and the other doesn't, then we have a problem. It must
work if you make the first letter lowercase, as that is part of the
javabeans spec.
>    Feel free to open a JIRA and we will take a look at it.

>> 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?

>>    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”) }
>>

>>
>> 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?
