Eugeny,
Another approach that we've talked about in the past around this same
problem is that rather than having a specific tab type for housing an
XBlock, we'd allow XBlocks to expose a course_view, which the XBlock could
use to render any course-level content (perhaps configuration details,
perhaps something like the Discussions tab, perhaps other uses). Those tabs
could be rendered for any XBlock type that appeared in the course.
Questions I have about your proposed implementation:
- what will the XBlock usage_key would be?
- where will the XBlock content (scope.content) would be stored in OLX?
- How does an XBlock define a view that's specific to the tab?
- For instance, I assume that the Discussion block would have a
different display in the tab than it would inline.
