'list' object has no attribute 'split'

TonyAlmeida — Fri, 21 Feb 2014 14:09:19 GMT

I have the following code and i am getting the following error, i am not sure why because the code works in python window in ArcMap but it doesn't work as a Add-in tool. Any would be appreciated.

error

Traceback (most recent call last):   File "C:\Users\talmeida\AppData\Local\ESRI\Desktop10.1\AssemblyCache\{BB229966-100D-4482-A3FE-B298BD262597}\AddPoints_addin.py", line 55, in onMouseDownMap     add_fields = add_fields.split(';') AttributeError: 'list' object has no attribute 'split'

Instead of

if type(add_fields) != list:

if not isinstance(add_fields, list):

or even better:

if isinstance(add_fields, basestring):

jscheirer thank you for the response.

I replaced the line

if type(add_fields) != list:

With broth of your suggestions.
first with

if not isinstance(add_fields, list):

I get the following error.

Traceback (most recent call last):
  File "C:\Users\talmeida\AppData\Local\ESRI\Desktop10.1\AssemblyCache\{BB229966-100D-4482-A3FE-B298BD262597}\AddPoints_addin.py", line 53, in onMouseDownMap
    if not isinstance(add_fields, list):
TypeError: isinstance() arg 2 must be a class, type, or tuple of classes and types

then i replaced it with

if isinstance(add_fields, basestring):

I got this error

Traceback (most recent call last):
  File "C:\Users\talmeida\AppData\Local\ESRI\Desktop10.1\AssemblyCache\{BB229966-100D-4482-A3FE-B298BD262597}\AddPoints_addin.py", line 83, in onMouseDownMap
    edit.stopOperation()
SystemError: error return without exception set

ArcMap seems to just freeze.
My arcmap process icon just keeps going and going.
No point or anything is created after maybe 3 minutes of thinking.

You're shadowing the built-in list type by defining a variable as list. Don't do list = [], rename it something like cc_list.

after replacing list = [] with CC_list = []. I get passed that error but now come to this error.
