Has anyone gotten EntityQuery to work with AJAX pagination? Right now the only way I can
get it to work is by putting the EntityQuery component in CONVERSATION scope.
When it isn't in CONVERSATION scope it will not work properly. I can page forward
through the list and back through list. But after I leave the first page I can't ever
go back to it using repeated clicks of "Previous Page" or clicking "First
Page" Also, I can not access the last page of the list though repeated clicking of
"Next Page" or clicking "Last Page"
In both the First Page and Last Page not displaying, I can tell from the debug statements
that the query is getting executed with the correct firstResult and returning the correct
data. But the page does not update.
I don't see why I'd have to put the EntityQuery into CONVERSATION scope
non working example

from TestCode c" max-results="5"/>
