[jira] Commented: (WICKET-627) onBeforeRenderChildren should be
made protected
[ https://issues.apache.org/jira/browse/WICKET-627?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12502448 ]
Alastair Maw commented on WICKET-627:
-------------------------------------
Have fixed half of this issue - it's now protected. However, it could do with a similar flag check to onBeforeRender() to make sure people have called super.onBeforeRenderChildren(), otherwise we'll break MarkupContainers.

> I've discussed this with Johan and we think we need to make onBeforeRenderChildren() protected.
> <AlMaw> I have a ValidationTaggedForm extends Form.
> <AlMaw> And in onBeforeRender, I call visitChildren(validationTaggingVisitor)
> <AlMaw> And the validationTaggingVisitor adds a behaviour.
> <AlMaw> If I have a ListView in the Form, onBeforeRender for the Form is called before the ListView populateItem calls.
> <AlMaw> Thus the components added in the ListView aren't visited.
> We can't just swap the order of the calls to onBeforeRender() and onBeforeRenderChildren() in Component#beforeRender() because that will break existing code and the repeaters. Besides, someone will only want to do things the other way around at some later date (e.g. attach a behaviour to a parent using a child then needs to reference/find).
> Suggested solution is to make onBeforeRenderChildren() protected, which will allow as much flexibility as you like.
