 Description   

following code throws exception errors (please see attached file) when the amount of contentNodes cannot be divided by 4 (results in an integer)

<cms:contentNodeIterator contentNodeCollectionName="contentCollection" step="4">
<cms:includeTemplate/>
</cms:contentNodeIterator>

if the amount of nodes can be devided by 4, then iteration with step="4" works properly. otherwise it throws an nosuchelementexception. i assume this occurs because after the last iteration haschild() is true, but if there are only 1,2 or 3 nodes left contentNodeIterator is missing the 4th node. the example could be also done with 3 or 5,6,... and it gets more complicated if one uses the 'begin' and/or 'end' attribute as well.

Given the thousands of other issues we have open that are more highly requested, we won't be able to address this issue in the foreseeable future. Instead we will focus on issues with a higher impact, and more votes.
Thanks for taking the time to raise this issue. As you are no doubt aware this issue has been on our backlog for some time now with very little movement.
I'm going to close this to set expectations so the issue doesn't stay open for years with few updates. If the issue is still relevant please feel free to reopen it or create a new issue.
