I am on ArcGIS 10.1 SP1 (Build 3143)
I have a python toolbox that is producing a number of shapefile outputs that I would like to add to the ArcGIS TOC.
Problem I am having is that whilst the layers add to the TOC while the tool is running when it completes the layers are deleted, and I can't seem to find a way to avoid this.
Anybody have any ideas? My code (pretty standard) is below:
mxd = arcpy.mapping.MapDocument("CURRENT")
df = arcpy.mapping.ListDataFrames(mxd."*")
addLayer = arcpy.mapping.Layer(outputFeatureclass)
Thanks for any help!
