[#6645] - Pagination issues when unset items at getItems()
- Expected Behaviour
- 28 Jan 2016
- Medium
- Build: master
- # 6645
Steps to reproduce the issue
At any component /models/bars <-- bars is the plural of model bar (could be articles or whatever)
Unset some (or all for example's sake) items at public function getItems()
for ($x = 0, $count = count($items); $x < $count; $x++)
{
unset($items[$x]);
}
Expected result
I would expect the pagination to contain no pages
Actual result
Depending on the number of items before unset varies from 1 to N pages
System information (as much as possible)
Joomla 3.4.1
definitely occurs on previous versions as well
Additional comments
I suspect that JModelList "calculates" pagination taking into account only the getListQuery and not the getItems() of the model
Is this normal?

Closing as expected behaviour based on the comment above

Because of performance reasons it tries to return only the count of the records as seen here https://github.com/joomla/joomla-cms/blob/staging/libraries/legacy/model/legacy.php#L326 in a second db call. If that is not possible it does a second query, getting all the items. So this behavior is expected.
