There is a problem when selecting a view above a list component, on portals.
This has been tested on privated cloud (v4.04) as well as in hosted cloud.
On portals, in "search results" type of pages (list of records) :
When checking the "show view selector" in the list component, multiple views are shown. The portal visitor can select views in the following component :
When the portal visitor switches views. (For exemple, if he selects the second view in the list), the name of the first view is still being shown.
In other words, if you look at the screenshot above : It doesn't matter which view you select, it will always print the name of the first view "M - Demandes a valider", as if the first view was selected.
The filtering works though, so you can see it switches views correctly.
