Steps to reproduce:

1. As Admin in Site1: Create a page (page1) with two columns, and set the column on the left as customizable (edit page -> customizable sections -> and check the left column)
2. As Admin: Create an user (member1) and set as member of the Site1.
3. As Admin: Add the AssetPublisher portlet (instanceable) and the Language portlet (non-intanceable) to the default view.
4. As member1: Customize your view adding another kind of portlet, for example, Web Content Display. Also, remove the Language portlet.
5. As member1: You decide to add again the Language portlet to your customized view.

Result: the last step is not possible.

Expected: user can add the portlet again because it isnt in his customized view.

Workaround: the member can reset his view to retrieve the language portlet and start the customization again.
