Hey Again,

This time I really need some help. I'm frustrated and just can't figure out
why this is happening. I am working with the rules engine to create our
purchasing ruleset. I am passing in 2 documents, 1 is the purchase order and
the other is a ruleresult document I came up with. As differnt rules are
fired I want to set flags in this document structure so when both documents
come back into the orchestration I can then route accordingly.

Here is my issue. I have created the following 3 rules:

Approval Needed:
IF
POTotal is greater than 20000
THEN
RuleResult.NeedsApproval = true

Check Items
IF
NOT
IsValidItem(POItems)
THEN
RuleResult.InvalidItems = true
Update(RuleResult)

Invalid Items
IF
RuleResult.InvalidItems
THEN
PO.FinalDisposition = Destroy

This is what is driving me nuts! I am testing the rules in the BRC and the
first go around I get a Match on all 3 rules. Therefore when the 2 rules
that will actually fire 'fire' and my update fact is executed the rule
engine never makes another pass to see that the RuleResult.InvalidItems is
now true which I want to have it fire the Invalid Items rule. It just starts
retracting all the facts and never makes a second pass. I am lost as to how
to structure my predicate on Invalid Items so it is not matched on the first
go around. Please someone help me, I've been tooling with this all morning
and am just stuck. I even tried the microsoft example for chainging:

Rule1
IF
ItemA.ID == 1
THEN
ItemB.ID = 2
Update(ItemB)

Rule2
IF
ItemB.ID == 2
THEN
ItemB.Value = 100

And this didn't work either..... I am obviously doing something wrong but I
dont' know what.

Here is the trace from the BRC perhaps it will help you all see what I am
trying to accomplish
