LoadFiles works, LoadURLs error in demo and custom implementation

[jjreicher]

1. In my implementation, the header is parsed just fine, but the image never displays. There is no error message. Other cases work fine! I have 5-6 similar examples though with this same issue. I'm using loadURLs.
2. In the online jQuery demo viewer, if I load the case with the file uploader...it works! Displays perfectly.
3. In the same demo viewer, if I load via URL--the image won't show. I get error messages ("not valid DICOM", etc) but they don't make much sense.

Emailed a sample file. Any help greatly appreciated!

Ok I figured out the source of the problem at least...! Still not sure why the difference between the two loading methods though.

Basically in the checks for "vr" if there is a custom DICOM field, and if that field has an empty vr, you'll get some nonsense errors and the page won't load. If you change isOtherVR to true, the file works. I think the function instead needs to first check if empty and accept/pass if so.

Hopefully I can issue a commit if confirmed that this works and doesn't break anything else, but I think this is the issue.

The isOtherVR variable you mention is there: dicomElementsWrapper.js#L231.

The problem seems to be related to the tag (0018,9445) (dictionary.js#L1179)... It is one of these placeholders: "For some Data Elements, no Name or Keyword or VR or VM is specified; these are "placeholders" that are not assigned but will not be reused." (ref: current/output/html/part06.html).
