Hi, My project is build in JSF, Hibernate and Faclets. i m using trinidad treetable tag to build a tree with multiselection nodes. Now i m facing a problem to initially selection of the nodes when page is loaded at the first time. i have tried alot to accomplish this task, but still unable to retain it. There is an attribute of "selectedRowKeys" in TreeTable which takes the object of "RowKeySet", but when i am building the tree in my bean, i don't know the RowKeys generated, so how do i get my desired RowKeys to be selected in the tree?
i am trying to provide the code below myTree.xhtml <tr:treeTable id="testTreeTable" value="#{RoleManageBean.tree}" var="node" rowSelection="multiple" initiallyExpanded="true" rowBandingInterval="1" horizontalGridVisible="true" verticalGridVisible="true" selectedRowKeys="#{ RoleManageBean.selectedRowKeys}"> <f:facet name="actions"> <tr:commandButton id="treeTableSelectButton" text="Submit Sel." action="#{RoleManageBean.treeTableSelect}" /> </f:facet> <f:facet name="nodeStamp"> <tr:column headerText="Name"> <tr:outputText value="#{node.name}"/> </tr:column> </f:facet> <f:facet name="pathStamp"> <tr:outputText value="#{node.name}"/> </f:facet> </tr:treeTable> MyBean.java public class RoleManageBean implements Serializable { private TreeModel tree; private RowKeySet selectedRowKeys = null; public TreeModel getTree() throws Exception { Application[] applications = dbops.getAllApplications(); List<Node1> empty1 = Collections.emptyList(); List<Node1> root1 = new ArrayList<Node1>(); List<Node1> apps = new ArrayList<Node1>(); for (Application application : applications) { Set<ApplicationPage> appPages = application.getApplicationPage(); List<Node1> pages = new ArrayList<Node1>(); for (ApplicationPage applicationPage : appPages) { pages.add(new Node1(applicationPage.getPageName(), String.valueOf(applicationPage.getPageID()), empty1)); } apps.add(new Node1(application.getApplicationName(), String.valueOf(application.getHomePage().getPageID()), pages)); } root1.add(new Node1("Applications", "0", apps)); tree = new ChildPropertyTreeModel(root1, "children"); return tree; } public RowKeySet getSelectedRowKeys() { selectedRowKeys = new RowKeySetImpl(); selectedRowKeys.add(String.valueOf("1,0")); System.out.println("called"); return selectedRowKeys; } public void setSelectedRowKeys(RowKeySet selectedRowKeys) { this.selectedRowKeys = selectedRowKeys; } Any guideline will be appriciated. Thanks in Advance Majid.
