Java getdata parent node
The JSF and primefaces versions can be seen in the pom.xml I paste here:Ĭom.Ĭlass for data information for the tree: Document.javaĬode: Select all package. by exists and getData API calls, and the watches left on the parent node by. Tested in chrome and opera with the same behavior. Some successful ZooKeeper API calls can leave watches on the data nodes in. The server used is apache tomcat 8.0.26 in windows. The former excludes the context and the latter includes it. One can navigate to higher levels of the XML tree (parents, grandparents, great-grandparents, and so on) using either ancestor:: or ancestor-or-self. I tried different combinations of updating properties, including partiallySelected property update, but I couldn't fix the problem. The latter is a shorthand for parent::node( )/X, which will select all siblings of the context node named X, including the context itself, should it be an X. Other combinations of selecting and unselecting nodes produce strange behaviors, too. Then the 2016->A->X node is unselected, and the 2015->A->Y node is selected! Then this problem is solved, but if you do next step:
JAVA GETDATA PARENT NODE UPDATE
I force to update the "selected" property to false in the onNodeUnselect method (and to true in the onNodeSelect method). In fact, by debuggin, in this moment in the page the checbox is unselected, as expected, but after running the code, it is selected automatically. If you debug the code, in this step, at the begining of the "onNodeUnselect" method, the selected property of 2016->A->Y is true, and false is expected. Then, the 2015->A->Y node is unselected, but the 2016->A->Y node is still selected. Nodes 2015, 2016, 2015->A and 2016-A are selected, too, so all its children are selected. To reproduce one of this strange behaviors, you can follow the next steps:
JAVA GETDATA PARENT NODE CODE
I attach my complete code at the end of this post. A button to show selected nodes are included in the page (It can be seen that selected nodes from selection property are not updated if the selected property of the node is updated programatically, but that is a minor problem that I think I could solve in the backing). I used the code showed in this web as sample and I modified it (. All JavaFX Node instances in the scene graph share a set of common properties which are defined by the JavaFX Node class. I used select and unselect p:ajax events and I use the update property to render the form again to see the changes in the tree. The JavaFX Node class,, is the base class (superclass) for all components added to the JavaFX Scene Graph.The JavaFX Node class is abstract, so you will only add subclasses of the Node class to the scene graph. But if I am selecting/unselecting nodes in 2015 branch, and then I select/unselect some node in 2016 branch, some unexpected strange behaviors could happen. If for instance, I only select and unselect nodes in the same branch, there are no problems.
1) Every left node is always lesser than its parent node. A binary search tree extends upon the concept of a binary tree. Each node can have one parent and a maximum of two children.
What I want to do is that when I select (unselect) the 2015->A->X node, the 2016->A->X is selected or unselected, too, and viceversa. The binary tree is a tree where each node (except the leaves) has two children. The problem happens by selecting or unselecting a node programatically. Since inner interface is static by default, you can't refer to T from static fields or methods.I am having some problems with tree nodes (I tried it with Tree and TreeTable and the problem is the same).
The error is because you are accessing a non-static instance variable from within a static methodĪll member fields of an interface are by default public, static and final.
