[jboss-jira] [JBoss JIRA] (DROOLS-5076) Rule compilation fails with date constraints on nested fact types

[Matteo Casalino (Jira)]

     [ https://issues.redhat.com/browse/DROOLS-5076?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Matteo Casalino updated DROOLS-5076:
------------------------------------
    Description: 
As of Drools 7.32.0.Final, patterns containing constraints on nested dates won't compile.

For instance, given the following drl:

{noformat}
declare Fact
    n : Nested
end
declare Nested
    d : java.util.Date
end

rule "with nested date"
     when
      Fact(n!.d >= "01-Jan-2020", n!.d <= "10-Jan-2020")
     then
     end    
{noformat}

we get the following error:

{noformat}
Message [id=1, kieBase=forall-date-constraint, level=ERROR, path=org/drools/reproducer/rules.drl, line=-1, column=0
   text=Unable to Analyse Expression n.d >= "01-Jan-2020":
[Error: Comparison operation requires compatible types. Found class java.util.Date and class java.lang.String]
[Near : {... n.d >= "01-Jan-2020" ....}]
                    ^]
Message [id=2, kieBase=forall-date-constraint, level=ERROR, path=org/drools/reproducer/rules.drl, line=-1, column=0
   text=Unable to Analyse Expression n.d <= "10-Jan-2020":

[Near : {... n.d <= "10-Jan-2020" ....}]
                    ^]
{noformat}

We don't reproduce with Drools <= 7.31.0.Final
