We are migrating from 6.2 to 6.5.
Looks like this paricular "Select All" behavior was changed with 6.5, based on details in release notes [https://helpx.adobe.com/experience-manager/6-5/release-notes.html]
However, we have a requirement to have it working, as it was in 6.2.
Tried debugging on which are the files to be changed etc. So far, have not got any leads on this.
Any thoughts/pointers on how this can be achieved in 6.5, will be really helpful.
6.2 relied on lazy loading, that's why things like Select All and Sorting sucked and only manipulated the first whatever number of elements that loaded.
Good luck satisfying your requirement, you'd likely have better results selling the merits of a "select all" feature actually working as intended rather than to only select 40 results at a time.
hmm true, will try to go based on what you have mentioned.
