This trims down the list of objects to 60 objects (which makes 3
batches). I would like to display that number (60) somewhere on my
page. However, these are the results I get:
displayGroup.allObjects().count() 350 (the total
number of fetched objects)
displayGroup.displayedObjects().count() 25 (the
number that fit on that page), or 10 (for the last page)
displayGroup.setNumberOfObjectsPerBatch(0);
displayGroup.displayedObjects().count() 60 (the
number of qualified objects -- this is what I want)
That seems like a bug to me. Maybe that's why I still don't use
display groups. :-)
I do not think so! A display group "manages" 2 arrays; namely,
allObjects and displayedObjects. Each has its own qualifier; well
indeed the allObjects is qualified by the data source and the
displayedObjects by the display group it self.
This has an adventge: while the data source hits the db with its
qualifier, you can change the displayedObjects "in memory", which is
faster.
