Using arcpy.Describe Method on Annotation layers

[MikeMacRae]

I'm testing layers in the current document using the

Describe

function. My code is:

for lyr in arcpy.mapping.ListLayers(df):
     if(lyr.isGroupLayer == False and lyr.isRasterLayer == False):
         x = arcpy.Describe(str(lyr))

It's throwing an error on the annotation layer:

"LSDSectionBoundaryAnno\Default" does not exist

I'm thinking that the Describe function doesn't like annotation layers or the subclasses? Can I use Describe on annotation layers and if not, how would I filter out annotation layers? There doesn't seem to be a 'isAnnotationLayer' property.

Thanks,
Mike

Annotation feature classes can be described, but it is that default subclass that is messing you up. I would try something like this instead:

for lyr in arcpy.mapping.ListLayers(mxd):
    if lyr.isFeatureLayer:
        x = arcpy.Describe(lyr)

It talks about this in the third paragraph under the Discussion section in the Layer (arcpy.mapping) help page.
