I am writing an arcpy script that at one point uses MultipleRIngBuffer, and then modifies the attribute table of the features that are created. I have created a GUI for the tool as a script in a toolbox. The first parameter is the input feature class, which will be buffered and have its attribute table modified. It is of "Feature Layer" type.
If I use the table of contents entry for the feature class which I wish to buffer, I get this error:
ERROR 000732: Input Features: Dataset GPL0 does not exist or is not supported
However, if I use the direct path to the feature class (i.e. through ArcCatalog), it works.
I am hoping to resolve this somehow because I want users to be able to drag and drop TOC entries into the GUI like they can with any other tool.
