[Trinidad] request backed TreeTable

Hi, I have a Trinidad TreeTable displaying my hierarchy of selectable data which works fine.

The problem I having is that when I user selects a row in the table and then navigates away from the page and the returns to the page, the treeTable selection is persisted and the row is expanded and selected? My backing bean is request scoped, which confuses me?

Does anyone know how I can force the TreeTable to return to its original state on every new request?

Many thanks,

Andy

Hi Andrew, 
 
Is the binding attribute set in the <tr:treeTable> tag?  If so, and if
you do not want to persist state across requests, you should clear this
attribute -- especially if the bean in the binding attribute is session
scoped.
 
Take a look at this article for more information:

ic-adf-faces-tree.html
 
Hope this helps,
Todd

Thanks Venktra,

 

My colleague tells me they have tried progmatically clearing the
selectedRowKeys and disclosedRowKeys in the backing bean with no
success, the selected state is persisted and the tree remains expanded.
Removing the context-pararm has had the desired effect I just cant find
any decent documentation around
org.apache.myfaces.trinidad.CHANGE_PERSISTENCE.

 

Regards

 

Andy

Hi Andrew,

I believe this may not have anything to do with change persistence. The
selection and the expansion state is part for the component state
(SaveState, RestoreState). 

One possibility is that you use a request scoped bean to bind the
selectedRowKeys and disclosedRowKeys attributes via EL.

Venkata

Does anyone know here this is documented so I can determine the effect
of removing this will have on my application? I guess this has been set
for a reason :-)

[Trinidad] Help or Links to documentation on Trinidads's conversation and context mechanism

Hi,

Regarding a couple of issues with Seam 2.0 RC 1  , possibly because of the 
combination with Trinidad and other tag libraries, we
are looking for some information on the way Trinidad's conversation and 
context mechanism works,
some links on documentation or also some hints on the mechanism would be 
helpful.

Many thanks,
Wolfgang.

Re: [Trinidad] request backed TreeTable

Posted by omaji7 <om...@gmail.com>.
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
