How to test for existence of AcroXFA test objects?

Question

Hi -
I'm writing scripts to test an XFA form with dynamic subforms.  For example, at the end of Part 4, the user hits a Validate button, and if their data is correct, then the Validate button disappears and a Part 5 subform appears.
So my script looks something like this:
Function GetButtonPart4Validate()
   Set GetButtonPart4Validate = PDFDoc("TestForm").AcroXFAForm("form").AcroXFAForm("form1")
.AcroXFAForm("sfPart4").AcroXFAButton("sfValidate")
End Function
Function GetPart5()
   Set GetPart5 = PDFDoc("TestForm").AcroXFAForm("form").AcroXFAForm("form1").AcroXFAForm("sfPart5")
End Function
GetButtonPart4Validate().Click
PDFDoc( "TestForm" ).WaitProperty "ready", true, 60000  ' Wait for event processing complete
If DataTable("boolValidates", dtLocalSheet) = "TRUE"  Then
     If( GetPart5().Exist ) Then
          ' A: Checkpoint Succeeds: Validation was successful
     Else
          ' B: Checkpoint fails: Validation failed
     Endif
Else
     If(  GetPart5().Exist ) Then
          ' C: Checkpoint Fails:  Validation was unexpected
     Else
           ' D: Checkpoint Succeeds:  Validation failed as expected
     Endif
Endif
Unfortunately it appears that XfaSubForm.Exist always returns TRUE.  In other QTP testing domains (eg "Exist Property (WinObject)" in QTP Help), the documented behaviour of the Exist property is to be true if the desired test object can be found in the application-under-test. Typically this means that when the script tries to access an XFA widget which doesn't exist (even something like GetPart5().getROProperty("visible") ), the script stops and thinks for a minute or so, and eventually produces a test error that the object doesn't exist then muddles onward. It is the "stops and thinks for a minute or so" which frustrates me, since these are delays which I am trying to avoid.
Another possible angle I looked into was counting the subforms under Part 5's parent.
PDFDoc("TestForm").AcroXFAForm("form").AcroXFAForm("form1").RefreshObject
PDFDoc("TestForm").AcroXFAForm("form").AcroXFAForm("form1").AcroXFAForm("sfPart5").Refresh Object
' check to see if there is a 'sfPart5'
Dim MyChildren, i
Set MyChildren = PDFDoc("TestForm").AcroXFAForm("form").AcroXFAForm("form1").ChildObjects
For i=0 to MyChildren.Count - 1
    print i & " name=" & MyChildren(i).GetROProperty("name")
Next
This also seems to fail:  Part5 doesn't appear among its parent's children (at least before QTP actually tries to use it).
The PDF Test Toolkit User Guide doesn't specifically mention that Exist or RefreshObject or ChildObjects are implemented, so I can't say AcroQTP isn't working as designed, but if you're looking for suggestions for improvement, I'll vote for fulfilling these parts to the QTP.  Please confirm my conclusions that these are not properly implemented, or whether I'm missing something.
In the meantime, do you have any recommendation on how to proceed?  My present workaround is to look for a "validation error" windows dialog that indicates Part 5 won't exist, but this won't work in future test scripts.
Cheers,
Brent

SOLUTION *1* :-
select customer_name

where account.account_number=depositor.account_number and

group by customer_name
having count(account.account_number) <=1
ok running correctly
That finds customers who have exactly one account at Perryridge.
The assignment is to find customers who have at most one account at Perryridge. You need to include customers with 0 accounts at Perryridge, as well. You could use an outer join, or MINUS, or a NOT IN subquery, or a NOT EXISTS sub-query (as mentioned above) to do that.
Can there be customers who have no accounts at all, at any branch? If so, you'll need to use the customer table in this problem, as well as depositor and account.

select D1.customer_name

          D2.account_number=A1.account_number and

gives error:-
where unique
..........*^*
ERROR at line 3:
ORA-00936: missing expression
Logic of both solution are correct . But Solution 2 gives error in oracle. I want unique construct to work.Sorry, it doesn't in Oracle. I don't know of anything like that in Oracle.
Does "WHERE UNIQUE (SELECT ...)" work in some other database system? Which?
How to do it. Or How can i test for the absence of duplicate tuples ??????
Your Solution 1 is the best way to find customers with exatly 1 account (rather than 0 or 1 accounts) at Perryridge. Is there any reason why you wouldn't want to use it, if you ever needed to find customers with exactly one account there?
