LotusScript:  problem using Evaluate statement.

pentapod asked
Last Modified: 2013-12-18
I have a form with 6 fields, called

When I put test fields on the form I can see that


gives exactly the right results... ie if the user's name is Approver_3, then it returns "3".

I have an action button, behind which is various script including:

Dim Authorized As Variant

However, the Evaluate statement above doesn't work.  No matter what, I get Authorized(0) = 0.

What am I doing wrong??

OK, I changed the code to:

     Dim session As New NotesSession
     Dim ws As New notesuiworkspace    
     Dim db As NotesDatabase
     Dim uidoc As notesUIDocument
     Dim approverlist As String
     Dim Authorized As Variant

     Set uidoc=ws.currentDocument

Approverlist = uidoc.fieldgettext("approver_1") + ":" + uidoc.fieldgettext("approver_2") + ":" +uidoc.fieldgettext("approver_3") + ":" +uidoc.fieldgettext("approver_4") + ":" +uidoc.fieldgettext("approver_5") + ":" +uidoc.fieldgettext("approver_6")
         Authorized=Evaluate("@Member(@UserName;'"+ Approverlist +"')")

.... It doesn't give an error, but it still doesn't work.  I can see that Approverlist contains my hierarchical name, as well as others separated by :s, but Authorized(0) = 0.

Any thoughts?

Simply Pentapod,
The Approvelist is not a real LIST to Notes the way you created it.  Use this:

Authorized=Evaluate("@Member(@UserName; @Explode('" + Approvelist + "';':'))")



Do I need to change the creation of Approverlist?  Because it still isn't working... sigh...  :(

My Approverlist looks like this:

"Pentapod/BR/SPE:Fred Bloggs/BR/SPE:John Doe/UK/EU/SPE:::"

My @username is Pentapod/BR/SPE

@username returns the full heirarchical name, its not returning 'Pentapod/BR/SPE'!  Are you sure that 'Pentapod/BR/SPE' is stored in the field (in that exact syntax) on the form?  If it is then in the formula change from @username to @v3username.



Oh - you're right!

OK, using
     Authorized=Evaluate("@Member(@name([CN];@UserName); @Explode('" + Approvelist + "';':'))")

and changing Approverlist so that it uses CN format only, it still doesn't work though...

Maybe there's a better way of going about this.  All I want to know is how, using LotusScript, to tell whether the current user is one of the users listed in the fields on the form.


This is the simplest of ways!  Why you want to complicate things with script?

Just tell me whats the formula in the field, or give me a sample field value...the formula that fills approver_1 for instance.



There is a form that the user creates, to request equipment purchase.  The user fills in the equipment details and prices, and then lists the names of the approvers in the fields Approver_1, Approver_2, etc.  The number and names of the approvers vary depending on what equipment is being purchased and for who, so this information can't be fixed.

Then the user presses a "send to approvers" action button and the database sends an email to the first approver with a doclink.  The first approver goes to the document and clicks on an "approve" or "reject" action button at the top.

The Approve button has to: 1. check that the user who clicked it is one of the approvers listed;  2. stamp "approved" with the date and time if the user is an approver; 3. find the next approver (if there is one) and send an email with doclink; and 4. check to see if that was the last approver, and if so, change the status to "approved" and notify the initiator of the request.

Right now I have got it to work by doing it another way.

     approver(0) = uidoc.fieldGetText("Approver_1")
     approver(1) = uidoc.fieldGetText("Approver_2")
     approver(2) = uidoc.fieldGetText("Approver_3")
     approver(3) = uidoc.fieldGetText("Approver_4")
     approver(4) = uidoc.fieldGetText("Approver_5")
     approver(5) = uidoc.fieldGetText("Approver_6")
     For i = 0 To 5
          If currentuser(0) = approver(i) Then
               Authorized = 1
          End If

Still, it would be nice to know how to manipulate a list using script.

There is a whole section in the help file on Lists.  Its really simple, a list is associated with an array.  But when you get a value from the ui with fieldgettext, u will get a string value.  You should use the backend and u will capture the list in an array eg item=doc.approver_1, now item will be an array.  You can use a forall loop or a for loop to traverse the array.  For assigning, use doc.replaceitemvalue("approver_1",array).  Thats a short description.



Don't have time to try it at the moment, but I'm accepting your answer as I'll be travelling for the next 3 weeks.  I'll check it all out when I get back.  Anyway the database is working with the work-around so it's no longer urgent.  Thanks for the help,
