Hi, For https://issues.apache.org/jira/browse/WICKET-5196 I tried to make AjaxFormValidatingBehavior a bit friendlier for extension.
Please check AjaxFormValidatingBehavior - https://git-wip-us.apache.org/repos/asf/wicket/repo?p=wicket.git;a=blob;f=wicket-core/src/main/java/org/apache/wicket/ajax/form/AjaxFormValidatingBehavior.java;h=1afcc68533b23b9888112eca0509158b10f99f55;hb=29c952458a8c55974d8e8787fb8cc674e4463824 and the change in its usage - https://git-wip-us.apache.org/repos/asf/wicket/repo?p=wicket.git;a=commitdiff;h=29c952458a8c55974d8e8787fb8cc674e4463824 What do you think ? This change is only for 7.0.0.
