Description Tom McKay 2012-02-08 18:00:18 UTC

Description of problem:

When manifests contain more than a handful of products, the load time of the Systems/Subscriptions becomes large, making it difficult/impossible to use.

The reason is that for each product in the manifest, the engineering sub-products are listed. Then for each of those, the repo information is listed (GPG, url, etc.). This last detailed information results in both a lot of calls to the backend candlepin as well as a large amount of processing by the javascript in the client browser.

There are several possible remedies:
1) Do not show the detailed information
2) Make the call to get details be AJAX
3) Add a small pagination to the displayed subscriptions

For now R&D will implement #1 with an eye towards picking a better solution in version 1.X

    788657 - to not display product content details in the System/Subscriptions tab of UI

Went w/ option #1 with an eye toward reworking all the subscription pages later.

To test, import expand the subscriptions listed on the Systems/Subscriptions tab and note the listed products expanded below: Just the name(s) are shown.

I have no access to any manifest with more than about 5 products.  However I did verify that the subscriptions pane just shows the name of the product.  Verified, CloudForms System Engine Version: 0.1.304-1.el6
