Improved version, use a Managed Bean (does not need to be managed can be just a class)
Java class:
package com.my.javaclass;
import java.io.Serializable;
import com.ibm.xsp.extlib.tree.ITreeNode;
import com.ibm.xsp.extlib.tree.impl.BasicLeafTreeNode;
import com.ibm.xsp.extlib.tree.impl.BasicContainerTreeNode;
import com.ibm.xsp.extlib.tree.impl.BasicNodeList;
public class javaclass extends BasicNodeList implements Serializable {
private static final long serialVersionUID = -7600042596799645230L;
public javaclass() {
BasicContainerTreeNode newContainer = new BasicContainerTreeNode();
newContainer.setLabel("Dynamic Container Node");
BasicLeafTreeNode newNode = new BasicLeafTreeNode();
newNode.setLabel("Dynamic Basic Node");
newNode.setSubmitValue(/*some value you want to submit*/);
newNode.setSelected(/*some boolean function*/);
newContainer.addChild(newNode);
addChild(newContainer);
}
}
Thank you so much for the code! This solves a huge problem that I have.
ReplyDeleteCan you tell me if I generate a dynamic set of BasicLeafTreeNodes by reading some documents to generate the setSubmitValues, how can I go back and update the setSelected value to true when a node is clicked?
Well when creating that dynamic set, you need to add a submitValue and a selected value on each node.
ReplyDeleteIn the navigator onClick event you add something like this :
(you can also use a sessionScope variable instead of this managed java bean class Main.Navigation)
Just store the submittedValue somewhere...
Main.Navigation.currentCategory = context.getSubmittedValue();
Example :
ContainerNode1
- ContainerNode2
- newNode1
// the submit value should contain the entire string parent\\child\\child
newNode.setSubmitValue("ContainerNode1\\ContainerNode2\\newNode1");
newNode.setSelected(Main.Navigation.currentCategory.equals("ContainerNode1\\ContainerNode2\\newNode1");
