I have been plugging along quite deligently on a GUI tool that I have posted on here before. This time i am asking about an error I get that seems to occur when i try to use insertRow() along with a registeredVersion of a featureclass.

The script works perfectly fine when it is not operating on a versioned data set, and so I am a little confused about how to proceed.

Error when edit.startEditing(True, False)

workspace already in transaction mode

Error when edit.startEditing(True)

error return without exception set

Here is some code I am using, the input is just a .csv of y,x coordinates.

import arcpy, os f = open(".../swPointTest.txt") lstNodes = f.readlines() try:     edit = arcpy.da.Editor(r"Database Connections\PW_Tax_sql_PW.sde")     edit.startEditing(True, False)     cntr = 0     with arcpy.da.InsertCursor(r"Database Connections\PW_Tax_sql_PW.sde\PW.PW.swNodes",("SHAPE@XY", "ASBUILTID","PROJECTID")) as cur:         for node in lstNodes:             cntr += 1             vals = node.split(",")             latitude = float(vals[0])             longitude = float(vals[1])             ABID = "FTR-" + str(cntr)             PID = float(1354.07)             print("Latitude: " + str(latitude) + " x Longitude: " + str(longitude))             rowValue = [(latitude,longitude),ABID,PID]             print(rowValue)             cur.insertRow(rowValue)             print("Inserted Node")     edit.stopEditing(True) except Exception as e:     print(e.message) finally:     f.close()

Thank you for any insight you may be able to provide.

Just to add, after a little bit of digging i managed to find a thread here about a similar issue has persisted since 10.0. It seems like my issue is related to this one.

For versioned data, we should start Edit session, without UNDO. So first parameter should be False

edit.startEditing(False)   (or)  edit.startEditing(False, False)

And use the startOperation & stopOperation methods on each feature insert.

See the simple example from help document - Editor example 2

I added your recommended changes but I continue to get the following errors

Editor.startEditing(False)

...

Editor.startOperation()

   > error return without exception set

Editor.startEditing(False, False)

...

Editor.startOperation()

   > workspace already in transaction mode

Here's what I use

edit = arcpy.da.Editor(workspace)
try:
    edit.startEditing(multiuser_mode=True)
    edit.startOperation()
    with arcpy.da.InsertCursor(in_table, field_names) as cursor:
        #
        # do stuff
        #
    edit.stopOperation()
    edit.stopEditing(save_changes=True)
except:
    # Attempt to clean up edit session
    try:
        edit.abortOperation()
        print "operation aborted in except"
        edit.stopEditing(save_changes=False)
        print "edit stopped in except"
    except Exception as otherErr:
        # Handle unexpected error when stopping edit
        print otherErr
        pass
    # Re-raise original exception
    raise
finally:
    del edit‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

You should be able to use Editor in a with statement to do all the cleanup automatically but I can never get it to work on versioned data.
