portlet preferences and portlet instances

[erezharari]

is it true that portlet preferences on user level is the same for the portlet instance for all its portlet windows?
say i have the same portlet instance multiple times in a page or multiple pages and the user changes the portal preferences - does this change apply to all the windows the portlet instance is in?

what about window properties? are they different for each user?

It is true for shared pages, it is not true in a dashboard.

[erezharari]

oh,
so in dasboards each window has dedicated set of user-portlet preferences?

[julien1]

yes.

it could be possible to achieve smth similar with shared pages but would require a modification of the CustomizationManagerService to return a key for customization based on the window id + user id instead of only the user id

here is the relevant code:

Instance instance = instanceContainer.getDefinition(instanceId);
 if (instance != null)
 {
 // If we are in the context of an existing user we get a customization for that user
 if (user != null)
 {
 String userId = getUserId(user);

 // And if it is in a dashboard context we get the per window customization
 if (isDashboard(window, user))
 {
 // That's how we manufacture dash board keys
 String dashboardId = window.getId().toString();

 //
 instance = instance.getCustomization(dashboardId);
 }
 else
 {
 instance = instance.getCustomization(userId);
 }
 }
 }
