Metadata.other.autodesc always returns undefined

I'm writing a button script that tries to get the image format (JPEG, GIF, PNG, ...) from an image file not taking into account its file extension.

The problem is that I can't find an ImageMeta property that returns this data but I noticed that the Description column in a Lister shows a string that contains what I'm looking for,
e.g. "1920 x 1080 x 24 PNG Image"

I have found in the documentation that the Metadata.other.autodesc property should return this string but I always get undefined as a result no matter the image file I use in my tests.

Here is a snippet of my code:

function OnClick (clickData) {
	DOpus.Output("\nTesting image metadata extraction...");
	var selectedFiles = clickData.func.sourcetab.selected_files;
	var file;
	for (var fileEnum = new Enumerator(selectedFiles); !fileEnum.atEnd(); fileEnum.moveNext()) {
		file = fileEnum.item();
		DOpus.Output("Image file: " + file.name);
		DOpus.Output("  > Description:     " + file.metadata.other.autodesc);
	}
}

It looks like it won't return a value unless you've actually got the Description column turned on in the Lister. We'll get that fixed for the next update.

Thank you. Turning on the Description column works ok. I'll leave it that way until a fix is released.
