But the same session is being reused to apply the second set of rules and the

I only see that drools pick the XOR-Group and just skips the AGENDA-GROUP
when it generates the drl for the decision tables.
Can somebody please verify the same and tell if AGENDA_GROUPs are supported
in Decision Tables?
Thanks

You can use eval expressions.
Try -
eval(m1.startDate.isBefore(m1.LDOS))
or
eval(m1.getStartDate().isBefore(m1.getLDOS()))
