We noticed recently the new warning message added to AEM bulk edit scenario, where user attempt to “Select all” and edit these sub-pages in separate tabs. The warning message says that “Bulk action not supported, The selected action Edit(e) will only have effect X selected items currently loaded…”. As we understand, the justification for that warning message is to let user know that not all sub pages might have been lazy-loaded, and that’s fine. That also explains why the massage doesn’t need to appear when pages have been selected manually. The point is that the mentioned logic might be confusing when there are only few sub-pages to be selected by “select all”. In that case lazy logic is not the case and user can be sure that “select all” picks all the sub pages we have on the screen. Please consider extending that logic, because our customers feels uncomfortable with new behavior and confusing warning. (More detail you can find in thread for Case #E-000797571)
Changing this behavior will lead to better user experience. Also if some users often use Select all and Edit options together for smaller lists of sites it won't be that annoying.
Go to list of Pages where you have 6 elements
Choose Select all elements
Warning about Selecting only visible items is displayed
