Updating individual branches using a TableTree
Hello Everyone: I am looking for a way to leverage the TableTreehttps://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 NestedTreehttps://ci.apache.org/projects/wicket/apidocs/6.x/org/apache/wicket/extensions/markup/html/repeater/tree/NestedTree.html component. The following posthttp://stackoverflow.com/questions/19790545/stop-wicket-from-repainting-the-whole-page-after-each-ajax-call/19806978#19806978 states that when using a TableTreehttps://ci.apache.org/projects/wicket/apidocs/6.x/org/apache/wicket/extensions/markup/html/repeater/tree/TableTree.html, the TableTree#updateBranchhttps://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 NestedTreehttps://ci.apache.org/projects/wicket/apidocs/6.x/org/apache/wicket/extensions/markup/html/repeater/tree/NestedTree.html component overrides the updateBranchhttps://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#updateBranchhttps://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#updateBranchhttps://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 TableTreehttps://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 TableTreehttps://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?

Re: Updating individual branches using a TableTree
Hi, NestedTree utilizes its hierarchical markup to update the expanded branch only. This is not possible with a tabular markup. Either you - use NestedTree if you don't need columns and get partial updates for free - use TableTree because of needed columns and live with complete updates (similar to changes of sorting order in a DataTable) - or invent a solution that replicates the magic of the old (deprecated) tree implementation (it was able to update a subset or rows with a lot of specialized rendering code) Have fun Sven On 26.08.2015 21:20, Ephraim Rosenfeld wrote: Hello Everyone: I am looking for a way to leverage the TableTreehttps://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 NestedTreehttps://ci.apache.org/projects/wicket/apidocs/6.x/org/apache/wicket/extensions/markup/html/repeater/tree/NestedTree.html component.

Inserting/Persisting data into the DB
Having trouble getting my setTestValue method to persist my data in the db ..
i do not see any exceptions but data is not hitting the database.. I am
using Hibernate and postgres db

Wicket page test 3.0.1 is now available (for Wicket 7.0 and 6.x)
Dear all, Wicket page test 3.0.1 is now available. It now works with Wicket 7 (and 6.x) and can reliably wait for the loading of the response page. It is a library allowing you to unit test your Wicket pages easily, supporting AJAX and Javascript without changes to your pages. It's available from maven central. Check out the tutorial at http://wicketpagetest.sourceforge.net to get started! -- Kent Tong IT author and consultant, child education coach
