Couldn't find uploaded files in AtmosFox explorer

Karthik,

In Atmos, ObjectPaths that end with a slash are directories, and the upload helper requires the exact destination path, not the directory you want the file to be placed in.  Therefore, the code should be:

            ObjectPath path = new ObjectPath("/karthik/UploadFiles/Element.docx");

            string file = "C:/Users/karthike/Desktop/Element.docx";                                       

            ObjectId objectId = upload.CreateObjectOnPath(path,file, acl, null);

That's correct; the ObjectPath->isDirectory() method simply checks the syntax of path to see if it's a directory.  This is to keep all operations that involve network access constrained to the EsuRestApi object, preventing objects from having methods that create "hidden" network access to Atmos.  To check whether a directory really exists, you'll need to perform some operation such as getSystemMetadata() on it.  If it does not exist, an EsuException will be thrown with code 1003 (the requested object was not found).

Why does an Object path get asserted as a directory path (using esuPHP) even if the path is invalid?

$dirPath = new ObjectPath('/syntacticallyvalidbutnonexistentdirectory/');

Looking at EsuObjects.php it looks like it doesn't verify if the path actually exists, just if the ObjectPath looks to be valid syntax for a directory path.
