Script ending at loop

GeoffOlson — Mon, 23 Jun 2014 13:28:48 GMT

I'm having an issue getting a loop to run in my map. Something as simple as just trying to print "yay" won't iterate. Here's what I have to even a test that I can't get to run. Am I missing something?

mxd = arcpy.mapping.MapDocument("Current")
mapLyr1 = arcpy.mapping.ListLayers(mxd, "sampleLayer") [0]
cursor = arcpy.SearchCursor(mapLyr1)
for row in cursor:
 print "yay"

I tried the same script in a different mxd and it worked fine. But it still won't run in the map I created it for. What might cause this?

are there any rows in the table?

Yeah, it's not the layer name. Is it possible for an mxd to become corrupt that certain functions won't run?

I created a new mxd with my layers in it and it's working. So I don't know what caused the issue to begin with.

You might try running MXD Doctor on your original map.
