title: Photoshop scripting; dialogue box to open multiple documents, but getting "undefined"
body: <p>I have a dialogue box that allows the user to browse for one PSD file and then to browse for <em>multiple</em> TIF files.  When browsing for multiple TIF files, the text in the edittext box comes out as undefined.  Where as, if I just remove the ability to select multiple files, it works.</p>
