Re: [rules-users] Disabling strict mode in 5.4
The exception below is one of thousands like it. The problem is that the
data is coming from a Map and in strict mode mvel is unable to determine
the type. This rule works fine with strict mode off in 5.0.1 and 5.2.
The rule is:
rule "PEL_CHANGELIST_RES.AUTH.Actual First Name" extends
"PEL_CHANGELIST_RES.AUTH.Actual Person Base"
when
DalMap($existingValue : this['PERSON.FirstName'] != null) from
$existingPerson
DalMap($mergedValue : this['PERSON.FirstName'] != null) from
$mergedPerson
$lowerExisting : String() from $existingValue.toLowerCase()
String(this != $lowerExisting) from $mergedValue.toLowerCase()
then
$changeList.add(EncounterConsts.Episode.PersonRole.Person.path);
update($in);
end

Line 3 of the error message suggests that the parser isn't able to
determine the type of $existingValue as java.lang.String. So, strict
or no strict, the problem might be in the rule. Show?

How do you disable strict mode in 5.4? We are using the code below
and
getting strict mode exceptions. It worked in prior versions. Do you
have
to use the new APIs to disable strict mode?
PackageBuilderConfiguration pkgBuilderCfg = new
PackageBuilderConfiguration();
MVELDialectConfiguration mvelConf = (MVELDialectConfiguration)
pkgBuilderCfg.getDialectConfiguration( "mvel" );
mvelConf.setStrict(false);
mvelConf.setLangLevel(5);
PackageBuilder builder = new PackageBuilder(pkgBuilderCfg);
builder.addPackageFromDrl(new StringReader(drlString));
An example exception:
