Ah sorry.. It seems my first message hasn't been accepted by the user-list...
I post it again here:
After we upgrade to Drools v 5.5 there are hundreds of errors in test cases
related to our rules.
One of which is related to this ClassCastException which I noticed it occurs
when we have nested OR statements
Here is one example:
rule "employeeContributionStartDateAfterAccountStartDate"
ruleflow-group "EmployeeValidation"
when
// We only want this rule to fire when we are using the
create:Employee node. NOTE that the startDate or contributionStartDate
cannot be updated
EmployeeDetailsRulesModel(create == true)
// Get the date to validate
Employee( $contributionStartDate : contributionStartDate != null )
(or
(and
// i.e. The contribution start date and the account start
dates are both specified.
Account( $accountStartDate : accountStartDate != null )
eval( $contributionStartDate.compare($accountStartDate) < 0
)
)
(and
// The contribution start date is specified but the account
start date is not, but should be defaulted to today.
Account( accountId == null, accountStartDate == null )
SystemConstants($today : currentSystemDateWithoutTime)
eval(
$contributionStartDate.compare(jaxbUtils.toXMLGregorianCalendarDateOnly($today))
< 0 )
)
(and
// for an existing account where the account start date is
not specified.
Account( $accountId : accountId != null, $accountStartDate :
accountStartDate == null )
$composerMemberAccount : BaseMemberAccount() from
memberAccountDAO.getMemberAccount($accountId)
eval(
$contributionStartDate.compare(jaxbUtils.toXMLGregorianCalendarDateOnly($composerMemberAccount.getFundStartDate()))
< 0 )
)
)
then
error(ApplicationArea.EMPLOYEE, kcontext);
end
Here is the error message:
