How can I expand one node in a Tree2 component?
I am using this java code...:
public TreeModel getTerminalTreeData() {
TreeNode treeData = new TreeNodeBase("terminal", "Terminal", false);
TreeNodeBase terminalNode = new TreeNodeBase("terminalInfo", "Details", true);
treeData.getChildren().add(terminalNode);
TreeModel treeModel = new TreeModelBase(treeData);
TreeState treeState = treeModel.getTreeState();
if (!treeState.isNodeExpanded(treeData.getIdentifier())) {
treeState.toggleExpanded(treeData.getIdentifier());
treeModel.setTreeState(treeState);
}
if (!treeState.isNodeExpanded(terminalNode.getIdentifier())) {
treeState.toggleExpanded(terminalNode.getIdentifier());
treeModel.setTreeState(treeState);
}
return treeModel;
}
And this is mye jsp code..:
<t:tree2 id="terminalTree" value="#{searchAssitBean.terminalTreeData}" var="node" varNodeToggler="t"
preserveToggle="false"> <f:facet name="terminal">
<h:panelGroup>
<f:facet name="expand">
<t:graphicImage value="../images/yellow-folder-open.png"
rendered="#{t.nodeExpanded}" border="0"/> </f:facet>
<f:facet name="collapse">
<t:graphicImage value="../images/yellow-folder-closed.png"
rendered="#{!t.nodeExpanded}" border="0"/> </f:facet>
<h:outputText value="#{node.description}" styleClass="nodeFolder"/>
<%--<h:outputText value=" (#{node.childCount})" styleClass="childCount"
rendered="#{!empty node.children}"/>--%> </h:panelGroup>
</f:facet>
<f:facet name="terminalInfo">
<h:panelGroup>
.......
</h:panelGroup>
......
But all nodes are collapsed when the page is shown... What am I doing wrong?

BTJ

Solved it by changing my java method to..:
public TreeModel getTerminalTreeData() {
TreeNode treeData = new TreeNodeBase("terminal", "Terminal", false);
TreeNodeBase terminalNode = new TreeNodeBase("terminalInfo", "Details", true);
treeData.getChildren().add(terminalNode);
TreeModel treeModel = new TreeModelBase(treeData);
TreeState treeState = treeModel.getTreeState();
String[] tmp = treeModel.getPathInformation("0:0");
treeState.expandPath(tmp);
return treeModel;
}
Haven't tried your way...

Re: How can I expand one node in a Tree2 component?

You also need to expand "0". Have a look at UITreeData:
public void expandPath(java.lang.String[] nodePath)
URL: http://tinyurl.com/2dn8qx
If that doesn't work hopefully the author kicks in on this discussion.

And this should work? Because it doesn't for me... I now have the following java code..:
public TreeModel getTerminalTreeData() {
TreeNode treeData = new TreeNodeBase("terminal", "Terminal", false);
TreeNodeBase terminalNode = new TreeNodeBase("terminalInfo", "Details", true);
treeData.getChildren().add(terminalNode);
TreeModel treeModel = new TreeModelBase(treeData);
TreeState treeState = treeModel.getTreeState();
if (!treeState.isNodeExpanded("0:0")) {
treeState.toggleExpanded("0:0");
treeModel.setTreeState(treeState);
}
return treeModel;
}
(I have also tried 0:1, 0:2, 1:0 and 1:1...)
and jsp code..:
<t:tree2 id="terminalTree" value="#{searchAssitBean.terminalTreeData}" var="node" varNodeToggler="t"
preserveToggle="false">
but the tree appear with the nodes collapsed.... What am I doing wrong?

0:0 for root and the first child
0:1 for the root node and its second child
etc.

Resetting the expanded state of Tree2 component?
Posted by "Sanghavi, Shubhra" <Sh...@qwest.com>.
Hi,
tree2 component with clientside toggle is being used on the JSF page
as follows :
<t:tree2 id="clinTree"
binding="#{catalogBackingBean.clinTreeData}"
value="#{catalogBackingBean.treeData}"
var="node" varNodeToggler="t" clientSideToggle="true">
<f:facet name="X">
<h:panelGroup id="group01_ClinTree">
<f:facet name="expand">
<t:graphicImage value="../yellow-folder-open.png"
rendered="#{t.nodeExpanded}"
border="0"/>
</f:facet>
<f:facet name="collapse">
<t:graphicImage value="../yellow-folder-closed.png"
rendered="#{!t.nodeExpanded}"
border="0"/>
</f:facet>
<h:commandLink id="clinTreeLink"
immediate="true"
action="#{catalogBackingBean.evaluateClinTree}"
value="#{node.description}"
styleClass="smalltext">
<f:param name="clinTreeCd" value="#{node.description}"/>
</h:commandLink>
</h:panelGroup>
</f:facet>
<f:facet name="H">
<h:panelGroup id="group01_RC">
<f:facet name="expand">
<t:graphicImage value="../yellow-folder-open.png"
rendered="#{t.nodeExpanded}"
border="0"/>
</f:facet>
<f:facet name="collapse">
<t:graphicImage value="../yellow-folder-closed.png"
rendered="#{!t.nodeExpanded}"
border="0"/>
</f:facet>
<h:commandLink id="rcLink1"
immediate="true"
action="#{catalogBackingBean.loadRCDetail}"
value="#{node.description}"
styleClass="smalltext">
<f:param name="rcId" value="#{node.description}"/>
</h:commandLink>
</h:panelGroup>
</f:facet>
<f:facet name="W">
<h:panelGroup id="group01_RCValue">
<f:facet name="expand">
<t:graphicImage value="../yellow-folder-open.png"
rendered="#{t.nodeExpanded}"
border="0"/>
</f:facet>
<f:facet name="collapse">
<t:graphicImage value="../yellow-folder-closed.png"
rendered="#{!t.nodeExpanded}"
border="0"/>
</f:facet>
<h:outputText value="#{node.description}"
styleClass="smalltext"/>
</h:panelGroup>
</f:facet>
<f:facet name="L">
<h:panelGroup id="group01_clinleaf">
<t:graphicImage value="../document.png" border="0"/>
<h:commandLink id="clinLink1"
immediate="true"
action="#{catalogBackingBean.loadClinDetail}"
value="#{node.description}"
styleClass="smalltext">
<f:param name="clinCd" value="#{node.description}"/>
</h:commandLink>
</h:panelGroup>
</f:facet>
</t:tree2>
The tree is generated based on the user input from a drop down menu. The
issue is that the expanded state of the tree carries over from the first
tree to the next even though a new TreeModel is instantiated each time.
I tried setting togglePreserve to false , which basically collapses the
tree for each new request. But then it responds the same whether a new
tree was generated or some other action was performed on the JSF page.
I then tried usign UITreeData collapseAll method on clinTreeData too.
That did not help either. Am I missing something here ?

Ok, I have also tried using "terminal" and "terminalInfo" as node id, but should I use "terminal:terminalInfo" or?

tree2 uses the tree path (node indexes separated by colons), not the
tree identifier to expand/collapse nodes.
