Broken custom variables

[Ben Wagner]

Hi XNAT team,

  I've been getting some wackiness with custom variables lately, but have hit a real stumbling block today.  I'm trying to add new custom variable and I'm getting the following in the restlet.log:

Any suggestions?  Running 1.9.2.3.

Thanks,

Follow up with more wonkiness.  The custom variable finally showed up, but now none of the other custom vars on showing up in the session, but are in the XML.  See attached images.  Any suggestions?

Hmm..

So, it looks like the definition for this specific group of custom variables was lost/overwritten.  I added them back AND then RESTARTED and they reappeared.  It seems like with each edit lately I'm having to manually restart for them to show.  That's now how it's supposed to work.

Ideas?

Ben
