UIDoc.SaveAndClose() Close is not allowed when there is any open sub-transation

[Anonymous]

Hello,

I am trying to open a family and close the old family however I am reciving the message Close is not allowed when there is any open sub-transation, transation or transation group.

My code is something like this:

        Dim activeDoc As Document = commandData.Application.ActiveUIDocument.Document
        Dim oldUIDoc As UIDocument = commandData.Application.ActiveUIDocument
       Dim strNextFile As String = "c:\aa.rfa"

         Dim NewUIDoc As UIDocument = commandData.Application.OpenAndActivateDocument(strNextFile)
         Try
               oldUIDoc.SaveAndClose()
          Catch ex As Exception
             MsgBox(ex.Message)
         End Try

How do I close any open transactions and is OpenAndActivateDocument creating the ofending transation?

Any ideas?

Thanks

try setting the active document to be the new family opened.

Hello,

Thanks very much for the surgestion.

I tried to set the active document to the new family by setting the active view to one in the new family. But was still getting the same exception. "Close is not allowed when there is any open sub-transation, transation or transation group".

I tried to move the close to before the OpenAndActivateDocument however I then get the problem the active document cannot be closed.

Any other ideas?

Kind Regards

Do you have something like this above your class definition:

<Autodesk.Revit.Attributes.Transaction(Autodesk.Revit.Attributes.TransactionMode.Automatic)>

If so, you need to change it from Automatic to Manual and handle transactions yourself.  When it is set to Automatic, Revit starts a transaction for you prior to calling your code and then commits the transaction if your code exits successfully.  For information on handling transactions, see: http://wikihelp.autodesk.com/Revit/enu/2012/Help/API_Dev_Guide/0135-Advanced135/0142-Transact142

Hope that helps,

Thanks very much for the idea.

But my code already uses Autodesk.Revit.Attributes.Transaction(Autodesk.Revit.Attributes.TransactionMode.Manual

If you comment out the SaveAndClose method, does your code open and activate aa.rfa?  I'm wondering if the call to open that file is failing so that the document you are attempting to close is still the active document (which would give you the same message that you are getting about having an open transaction).
