latex2edx source_code not being saved to problem

[ichuang]

In Studio, when a latex high-level-source problem is edited, the changed latex source_code is not being saved back into the problem metadata.

This is happening in a largely stock edX instance, running fd4d81

The latex2edx conversion happens fine, and the newly generated xml is fine and is saved. Only the source_code field appears not to be getting updated.

Perhaps this has something to do with changes made in XBlock?

Looks like the issue is that module_edit.coffee (see https://github.com/edx/edx-platform/blob/master/cms/static/coffee/src/views/module_edit.coffee) no longer takes the data from elements with data-metadata-name (ie the textarea created in https://github.com/edx/edx-platform/blob/master/cms/templates/widgets/source-edit.html).

This is the line which used to do the right thing to get source_code saved into metadata:

     _metadata[$(el).data("metadata-name")] = el.value for el in $('[data-metadata-name]', $metadata)

but it has gone away due to the new metadata editing framework.

@cdodge?

I believe that @cahrens fixed this awhile ago. Please let us know if you're still seeing this issue!
