Pymel - can't create a string attribute

[Chad_Fox]

Hi all,

I'm trying to create a string attr, but im getting and error saying
the type specified is unknown. The pymel docs say otherwise.

sel = pym.selected()
pym.addAttr(sel[0], longName="ieCacheType", at="string" )

# Error: RuntimeError: Type specified for new attribute is unknown. #

Any thoughts on why?
Thanks!

try using dataType (dt) and not attributeType (at):

pym.addAttr(sel[0], longName="ieCacheType", dt="string" )

Since your selected node has methods you could just call straight off the node itself

sel[0].addAttr("ieCacheType", dt="string")

Foiled by a single letter, thank you for noticing that.

and thanks for the suggestion to use a method. I'll use this approach
instead.

Cheers,
