When you initially click the promote button for promoting a content view, you are presented with the lifecycle path.

The "Library" environment has a checkbox on it. When the generation of the page content is very slow, it can be very confusing because the publish action already put content into the library.

1) By default, when the lifecycle path is first displayed, there should be no checkboxes available.
2) Once the back-end finishes calculations, at that point we should update the page with a checkbox on the proper environment.
3) While calculations are being done on the back end, there should be a visual aid (spinner) to let you know something is happening.
