Problems removing caption from image?

pe2smugmug

So I'm not sure if I'm making the call wrong, but to remove a caption from an image, I have been using
smugmug.images.changeSettings, and setting the "Caption" argument to be a string of length 0, but this doesn't seem to have any effect for me.

I'm using the JSON interface on 1.2.0.

Has anyone encountered this before or is it more likely a bug in my code?

Thanks,
Evan

So some additional testing reveals that if I set the caption to a single space (ie. " "), then the caption appears to be properly deleted. Additional calls to get the caption show it to be saved as an empty string "".

Is this standard was for deleting a string?

Sending null or an empty string for many values ususally means: Do not update the string, leave it as it is.

Same for an image's caption: Sending an empty string for Caption means "Don't update caption, leave it as it is."

So what is the "correct" method for clearning a caption?
