The exception is caused by the stricter handling of $(htmlstring) as documented here: http://jquery.com/upgrade-guide/1.9/#jquery-htmlstring-versus-jquery-selectorstring

By replacing var dom = $(data); with var dom = $($.parseHTML(data)); in orchard-workflows.js on line 88 the problem can be fixed. The next exception is then raised on line 138 when calling jsPlumb.addEndpoint. ;-)

OK, http://jsplumbtoolkit.com/ doesn't seem to like JQuery 1.9
The second exception is difficult to fix because the min version of jsplumb is used.
BTW, it should be a script added in the ResourceManifest.

I can contact the owner... but before I do, has anyone else already done this?

I haven't found a way to submit an issue on the github project.

If you can contact him, it would help.

It took me some time, but I found out what’s going wrong. The problem is, that the response (data) is surrounded by some whitespaces.
$(data) (jquery < 1.9) ignored surrounding whitespaces, but jquery 1.9 does not. Hence the jquery object contains three DOM nodes (instead of one), two of them are text nodes. Because jsPlumb iterates over all DOM nodes, something within jsPlumb goes wrong (not sure what exactly is happening there).

Trimming the response before parsing it solves the issue.

var dom = $($.parseHTML($.trim(data)));

Submitted a wrong patch (6911), 6907 is the right one.
