dataTable linked with treenode
hi community..
I'm trying to work with a tree and a datatable...
I want that user can click a treenode and thus view a specific datatable.
datatable comes out from a query from a database....
so the click action could pass a value to a variable of datatable bean and customize it....
well my code is this
the htmlx page contain
<ice:form>
<table cellpadding="" cellspacing="0" border="2">
<tr>
<td width="25%" valign="top">
<ice:panelGrid columns="3" cellspacing="5">
<!-- first column, for tree navigation -->
<ice:panelGroup style=" solid gray; height:300px;width:200px;">
<!--
This is a very links tree comprising of only text nodes. The
expand and contract images are rendered because the "imageDir"
attribute on the tree component has been set to a known path.
-->
<ice:tree id="tree"
value="#{tree.model}"
var="item"
hideRootNode="false"
hideNavigation="false"
imageDir="images/xp/css-images/">
<ice:treeNode>
<f:facet name="icon">
<ice:panelGroup style="display: inline">
<h:graphicImage value="#{item.userObject.icon}"/>
</ice:panelGroup>
</f:facet>
<f:facet name="content">
<ice:panelGroup style="display: inline">
<ice:commandLink
actionListener="#{item.userObject.selectTable}"
value="#{item.userObject.text}"/>
</ice:panelGroup>
</f:facet>
</ice:treeNode>
</ice:tree>
<ice:outputText value="#{item.userObject.displayPanel}" />
</h:panelGroup>
</h:panelGrid>
</td>
<td width="75%" valign="top">
<ice:panelGrid columns="1" cellspacing="5">
<!-- Third column, for panel stack -->
<ice:panelGroup style="border: 1px solid gray; width:350px " >
<ice:panelTabSet>
<ice:panelTab label="#{tabset.tabs[0].label}">
<ice:outputText value="#{tabset.tabs[0].content}"/>
<ice:dataTable
value="#{inventoryList.carInventory}"
var="item"
columnClasses="categoryColumn, propertyColumn, valueColumn, unitColumn"
rowClasses="oddRow, evenRow"
styleClass="tableStyle">
<!-- Category -->
<ice:column>
<f:facet name="header">
<ice:outputText value="Category"/>
</f:facet>
<ice:outputText value="#{item.category}"/>
</ice:column>
<!-- Property -->
<ice:column>
<f:facet name="header">

</ice:dataTable>
</ice:panelTab>
<ice:panelTab label="#{tabset.tabs[1].label}">
<ice:outputText value="#{tabset.tabs[1].content}"/>
</ice:panelTab>
</ice:panelTabSet>
</ice:panelGroup >
</ice:panelGrid>
</td>
</tr>
</table>
</ice:form>
the action is registered by
<ice:commandLinkactionListener="#{item.userObject.selectTable}"
value="#{item.userObject.text}"/>
selectTable is the method of the backing bean
public class TableSelectUserObject extends IceUserObject {
// displayPanel to show when a node is clicked
private String displayPanel;
// panel stack which will be manipulated when a command links action is fired.
private TableBean Table;
/**
* Default contsructor for a PanelSelectUserObject object. A reference
* is made to a backing bean with the name "panelStack", if possible.
* @param wrapper
*/
public TableSelectUserObject(DefaultMutableTreeNode wrapper) {
super(wrapper);
// get a reference to the PanelStackBean from the faces context
FacesContext facesContext = FacesContext.getCurrentInstance();
Object TableObject =
facesContext.getApplication()
.createValueBinding("#{inventoryList}")
.getValue(facesContext);
if (TableObject instanceof TableBean){
Table = (TableBean)TableObject;
}
}
/**
* Gets the name of a panel in the panel stack which is associated with
* this object.
*
* @return name of a panel in the panel stack
*/
public String getDisplayPanel() {
return displayPanel;
}
/**

this.displayPanel = displayPanel;
}

*
* @param action JSF action event.
*/
public void selectTable(ActionEvent action){
if (Table != null){
Table.setObjectpath("moon/green/default/power/rtg");
}
}
}
this class call super....class treeBean where for each node I fix
branchNode1 = new DefaultMutableTreeNode();
branchObject1 = new TableSelectUserObject(branchNode1);
branchObject1.setText(sys_opt_array[j]);
branchObject1.setDisplayPanel(study_array+"/"+sys_opt_array[j]);
branchObject1.setBranchContractedIcon(sys_pic);
branchObject1.setBranchExpandedIcon(sys_pic);
branchObject1.setLeafIcon(XP_BRANCH_LEAF_ICON);
branchNode1.setUserObject(branchObject1);
branchNode.add(branchNode1);
tableBean is

public static InventoryItem[] resize(InventoryItem[] oldArray, int newLength)
{ if (newLength < 0 || oldArray == null)
throw new IllegalArgumentException();

int count = oldArray.length;
if (newLength < count)
count = newLength;
for (int i = 0; i < count; i++)

return newArray;

what I get is a static table.....nothing happen when I click... I suppose this happen because every time dataTable is created a new instance of path is read and it can't show any change......
someone could help me please?>
