Re: [Maya-Python] Re: .MFileIO.getReferenceFileByNode - // Error: (kInvalidParameter): Invalid parameter
The only thing you can do is use MGlobal::executeCommand to run the referenceQuery command in C++. I would log a defect with Autodesk about this, since it's such a big hole in the API.

[Maya-Python] Re: .MFileIO.getReferenceFileByNode - // Error: (kInvalidParameter): Invalid parameter
Most referencing commands/functions require you to pass in the reference node (i.e. node type is "reference"). It looks like you are trying to use a reference*d* node -- the sphere. You can query the reference node for a reference*d* object with `referenceQuery -referenceNode ref:pSphere1`. This should give you something like sphereRN. You can then get the MObject for sphereRN, pass it to getReferenceFileByNode and it should work. I don't think this particular referenceQuery functionality is exposed in C++. It really should be. It's annoying that MFnDependencyNode has isFromReferencedFile, but doesn't give you a way to query which reference it's a part of.

Re: [Maya-Python] List referenced files
Hi Marcus, Just a quick note about the fileNames attribute. It's actually obsolete and hasn't been used since Maya 6.0. It was only kept around for backwards compatibility. After Maya 6.5, reference paths are only accessible via the referenceQuery and the file command. Other attributes that are not used anymore include connectionList, setAttrList, addAttrList, deleteAttrList, brokenConnectionList, parentList, edits and multiParentList. placeHolderList is still used, though. It looks like the node docs don't really state this, but they totally should!

Re: [Maya-Python] List referenced files
It's stored in internal data structures. So the only way to access/change it is via the referenceQuery command, the file command or MFnReference.

Re: [Maya-Python] List referenced files
`file -q -list` will return all the file reference paths and string attributes marked as usedAsFilename. So it saves you from having to iterate over the nodes in the scene yourself. This is how Maya gets a list of files for the File Archive Scene feature. You can also access this functionality from outside Maya with the `maya.exe -archive scene_file` flag. As long as your plugin nodes mark their file path attributes as usedAsFilename, or override the MPxNode::getFilesToArchive function, it should pick up the paths.

[Maya-Python] Re: MFnNurbsCurve closestPoint issue C++
I ran into a very similar problem with MFnMesh:: getPointAtUV a few months ago. The solution in my case was to use the MDagPath constructor instead of the MObject one for your MFn* class. Apparently, functions that require a dag path won't actually return an error if you used the other constructor to build your MFn* object. They just fail silently. I logged a bug for the getPointAtUV issue. If this turns out to be a similar thing, I think you should log it. Autodesk needs to know how painful this is for customers. Maya's API should either return an error, or use the first path to an object under the covers. In fact, pretty much anything other than failing silently would have been nice.
