Although I understand the initial desire to have a web-view interface for the Maven Facade (similar to Nexus' ability to navigate the repo w/ a web browser), I think I'd recommend removing the capability entirely. The current implementation isn't complete and misses a few key areas. Overcoming every complex situation will be challenging and not worth the effort.
I would much rather require the use of the real S-RAMP UI. If there are specific use cases that the Facade view aimed for, implement them as improvements to the UI.
So, I'm advocating that we strip out the Facade view, JSPs, etc. entirely. Thoughts?
