Sven Ackermann commented on WICKET-6339:
----------------------------------------
Sorry, I do not have enough time at the moment to provide a test case. Our
setup is quite complex for this and I'm not allowed to provide you with our
code.
The problem is actually very obvious. If I have a situation like this:
RootMarkup
- MarkupFragment 1 (startIndex=2, size=10)
-- MarkupFragment 2 (startIndex=3, size=5)
then for MarkupFragment 2 the iterator will start at root index 2, but should
start at 5 (startIndex of its parent MarkupFragment 1 must be added).
> Wrong implementation of MarkupFragment.iterator()

> URL: https://issues.apache.org/jira/browse/WICKET-6339
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 7.2.0
> Reporter: Sven Ackermann
>
> The method returns {{getRootMarkup().iterator(startIndex, size)}}, but this
> only works when {{getRootMarkup() == getParentMarkup()}} or all intermediate
> {{MarkupFragment}}s start at index 0.
> The {{startIndex}} of all intermediate {{MarkupFragment}}s must be added,
> otherwise the iterator starts at a wrong index.
