Hello Everyone: I am looking for a way to leverage the TableTree<https://ci.apache.org/projects/wicket/apidocs/6.x/org/apache/wicket/extensions/markup/html/repeater/tree/TableTree.html> component while getting the Ajax updating behavior of the NestedTree<https://ci.apache.org/projects/wicket/apidocs/6.x/org/apache/wicket/extensions/markup/html/repeater/tree/NestedTree.html> component.
The following post<http://stackoverflow.com/questions/19790545/stop-wicket-from-repainting-the-whole-page-after-each-ajax-call/19806978#19806978> states that when using a TableTree<https://ci.apache.org/projects/wicket/apidocs/6.x/org/apache/wicket/extensions/markup/html/repeater/tree/TableTree.html>, the TableTree#updateBranch<https://ci.apache.org/projects/wicket/apidocs/6.x/org/apache/wicket/extensions/markup/html/repeater/tree/TableTree.html#updateBranch(T,%20org.apache.wicket.ajax.AjaxRequestTarget)> causes the entire table to be updated when expanding a node. In contrast, the NestedTree<https://ci.apache.org/projects/wicket/apidocs/6.x/org/apache/wicket/extensions/markup/html/repeater/tree/NestedTree.html> component overrides the updateBranch<https://ci.apache.org/projects/wicket/apidocs/6.x/org/apache/wicket/extensions/markup/html/repeater/tree/NestedTree.html#updateBranch(T,%20org.apache.wicket.ajax.AjaxRequestTarget)> method so that the table will appear with the sub-nodes expanded without having to refresh the entire table when expanding a node. If I try to override the TableTree#updateBranch<https://ci.apache.org/projects/wicket/apidocs/6.x/org/apache/wicket/extensions/markup/html/repeater/tree/TableTree.html#updateBranch(T,%20org.apache.wicket.ajax.AjaxRequestTarget)> with the same type of Visitor functionality in the NestedTree#updateBranch<https://github.com/apache/wicket/blob/master/wicket-extensions/src/main/java/org/apache/wicket/extensions/markup/html/repeater/tree/NestedTree.java> method to add back only the Item or RowItem component when the node is expanded, only the parent node appears with the expanded icon, but the sub-node does not appear. This makes sense because the TableTree<https://ci.apache.org/projects/wicket/apidocs/6.x/org/apache/wicket/extensions/markup/html/repeater/tree/TableTree.html> component presents sub-nodes as new rows in the table. Is it possible to override the behavior of the TableTree<https://ci.apache.org/projects/wicket/apidocs/6.x/org/apache/wicket/extensions/markup/html/repeater/tree/TableTree.html> component such that the entire table need not be updated when expanding a node? Or am I better off using the NestedTree<https://ci.apache.org/projects/wicket/apidocs/6.x/org/apache/wicket/extensions/markup/html/repeater/tree/NestedTree.html> component? Thank you in advance, - Ephraim
