The new portlet works pretty well, but there is one annoyance that you may want to eventually fix. New resource items do not show up after adding and saving and then going directly back into the configuration. You have to click on the Cancel button and then click on the Configure option again to see the new item. The steps to reproduce the problem are as follows:
1. Options -> Configure
2. Click on the “New Resource Link”
3. Type in the title, description, url, etc.
4. Select the groups
5. Click the save button
6. You will see the new resource item in the list.
7. Options -> Configure
8. You will not see the new resource item in the list.
9. Click on the cancel button.
10. Options -> Configure – now you will see the new item in config UI.
