> session properties data are shared by multiple pages launched on the same client. (we can compare in the vision “world” : the tag client for multiple desktop from the same vision client are shared) Is there a way to have some session data not shared by all pages of the same session ? My idea was to use session.custom.myprop[pageId] But I have to bind session custom prop data. Can we make some kind of indirect binding with session custom prop ?
