ASF GitHub Bot commented on WICKET-6503: ---------------------------------------- GitHub user svenmeier opened a pull request: https://github.com/apache/wicket/pull/250 WICKET-6503 render cleanup and ajax This is a combined effort to: - align Ajax requests with the way components are prepared in normal request, i.e. beforeRender is called on *all* components, before any of them is rendered - unify rendering of components separately as part of a page only vs. a whole page - improve performance by prevent unnecessary traversal of the component hierarchy - cleanup component's internal methods and flags You can merge this pull request into a Git repository by running: $ git pull https://github.com/apache/wicket WICKET-6503_ajax_feedback_prepare Alternatively you can review and apply these changes as the patch at: https://github.com/apache/wicket/pull/250.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #250 ---- ---- > Ajax refresh and feedback panel > ------------------------------- > > Key: WICKET-6503 > URL: https://issues.apache.org/jira/browse/WICKET-6503 > Project: Wicket > Issue Type: Bug > Components: wicket > Affects Versions: 6.28.0, 7.9.0, 8.0.0-M8 > Reporter: Martin Makundi > Assignee: Sven Meier > Labels: ajax > Attachments: AjaxRequestTarget.diff.txt, > Wicket8_Quickstart-IListener.zip, Wicket8_Quickstart-nested.zip, > Wicket8_Quickstart.zip > > Original Estimate: 4h > Remaining Estimate: 4h > > For normal rendering we have: > {{{{ /** > * We need to postpone calling beforeRender() on components that > implement {@link IFeedback}, to > * be sure that all other component's beforeRender() has been already > called, so that IFeedbacks > * can collect all feedback messages.

It seems to > be a typical problem that the feedback of an ajax update occurs too late. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
