-------------------------------------
Summary: introduce add(index,Component) in MarkupContainer
Key: WICKET-5170
URL: https://issues.apache.org/jira/browse/WICKET-5170
Project: Wicket
Issue Type: New Feature
Reporter: vineet semwal
Hi,
currently the only way to add new items at any index is removing all children
and then adding/recreating new children ,this might be ok for listview/dataview
since the ideal way of using them is to reconstruct at render ,this though ok
for them but will not be good for a repeater whose size is big/growing repeater
. fortunately markupcontainer provides everything to introduce a method like
add(index,component) which will have functionality like List#(index,element).
the advantages of introducing this method will be in places like an infinite
scroll repeater which can prevent the growing size by removing elements at
start/end depending on scroll position and later can add the items back at
start or end .
