JSF Command Link inside DataTable has to be clicked twice in order to work

I currently have a command link inside of a dataTable. However, when I go to the page and click the link nothing happens. It appears that the page is refreshed but looking at the logs nothing is done. However, if you click the same link again everything is updated properly. How do I get the command link to work properly? And, I have everything operating in the session scope.

No I do not have h:messages on the page. Just add it for debugging purposes. There might have been a validation or conversion error occurred which wasn't 'catched' by any h:message.
Unfortunately, upgrading to another version isn't an option at the moment. OK, I checked the MyFaces page and 1.1.5 is indeed the latest JSF 1.1 implementation.
Is there any other possible solutions that are more like a hyperlink than the command button. What exactly is causing the problem that I described?Have you tried if it works with a button or not? Only then we can be more sure about the cause of the problem.

Command Link inside of datatable

I have the following problem when I put a command link inside a datatable.
The action or actionlisteners never get called. Now here is the funny thing.
1. If I move the action link outside the datatable it works.
2. if I change the scope of the bean to session it works
3. if the datatable contains more than 1 row it works
The last one tells me this is a bug.
To test this I change the sql query to limit the result so 1 row would be returned.
The sql query returns a CachedRowSetImpl
I believe this is a bug.
<h:dataTable rows="6" first="0" id="table" binding="#{event.eventdata}" value="#{event.eventdetails}" var="eventdetail">
<h:column>
<h:commandLink value="#{eventdetail.title}" action="#{event.resaveEventaction}" actionListener="#{event.resaveEventdetails}" id="test" >
</h:commandLink>
</h:column>
<h:column>
</h:dataTable>

Here is some additional information that makes this more confusing.
The following code is used to populate the datatable
public CachedRowSetImpl getEventdetails(){
     CachedRowSetImpl rs2 = null;
     String selectedeventmy = selectedevent;
     int rowcount = 0;
     try {
          sql = "SELECT * FROM event where eventid='"+selectedeventmy+"' ";
          rs2 = RunQuery.mysql(sql);
          rowcount = rs2.size();
     } catch (Exception e) {
          // TODO Auto-generated catch block
          e.printStackTrace();
     return rs2;
where RunQuery.mysql is
public class RunQuery {
     public static CachedRowSetImpl mysql(String sql) throws Exception {
          CachedRowSetImpl crset = null;
          InitialContext initCtx = new InitialContext();
          Context envCtx = (Context) initCtx.lookup("java:comp/env");
          try {
               DataSource ds = (DataSource) envCtx.lookup("jdbc/associations");
               Connection conn = null;
     Statement stmt = null;
     conn = ds.getConnection();
     stmt = conn.createStatement();
     stmt.execute(sql);
     ResultSet rs = stmt.getResultSet();
     crset = new CachedRowSetImpl();
     crset.populate(rs);
     rs.close();
     stmt.close();
     conn.close();
          } catch (Exception e) {
               System.out.println(e.getMessage());
          return crset;
if I replace the line
String selectedeventmy = selectedevent;
with String selectedeventmy = "61";
it works properly.
selectedevent is populated from the following triggered by another action event on another page. ? The funny thing is if the result set returns more that 1 row all works ok.
public String viewDetails(){
     System.out.println("Running view Details");
     int selectedrow = eventlist.getRowIndex();
     Object selected = eventlist.getRowData();
     Map rowdata = (Map) selected;
     selectedevent = rowdata.get("eventid").toString();
     System.out.println("Selected Event:"+selectedevent);
     outcome="eventdetails";
     return outcome;
}

Command Link inside table to external website in popup window

Hi,
I am trying to have a command link inside a table which is on the tables id. I know that if I have control of the destination page I can use setCurrentRowKeyValue. However I do not have control of the external website. So I cannot add it into my faces-config.xml file? I have tried putting a GoLink and a GoButton but I get the following Illegal character in fragment error, when I put my destination URL in. An example of the format the URL is:
http://www.bbc.co.uk/radio?&music=#{row.PrimaryKey}&adf=123
Where I am adding in #{row.PrimaryKey} which is the Id of the row. I would like to have the new page opened into a pop up window if this is possible.
I am not sure if this can be done in the backing bean or whether my approach is the correct one?
Many Thanks
Steve

something like...
<af:goLink text="#{row.PrimaryKey}"
destination="http://www.bbc.co.uk/radio?&music=#{row.PrimaryKey}&adf=123"
targetFrame="_blank"/>Regards,

Styling command link inside a panel List

Hi All,
I have the following layout:
PanelBox
--panelList
-- CommandLink
I would like to style the command link under the panel List component. I have tried skinning the command Link component individually as well as applying styling to panel List component. Both didn't work( I haven't debugged this yet with firebug). From the skinning document, it has been mentioned that Style the root component of the command Link/Panel List. In this case, how do we style the command Link component. Basically, i would like to apply style for Link active, hover and focus.
Thanks,
Bala

As far as I am aware, you would need to skin the specific component irrespective of the parent componet/root.
For your usecase, you take look at the skinning demo application for the various skinning selectors for the command link at
http://jdevadf.oracle.com/adf-richclient-demo/faces/components/skinningKeys/commandLink.jspx
Thanks,
Navaneeth

Command Link with Datatable doesnt work

I had read the previosu posts stating that commandLink with the datatable will be corrected with the new version of Jsf- 1_1_01 .I installed the new version and the commandLink doesnt work inside a datatable still

try initialising the List attached to the dataTable
in the constructor or use an outputLink
-DevioutputLink is similar to <href in jsp.It cannot implement the actionListener and action parameters which a commandLink does. Using a constructor for initializing is fine but when i want it to implement certain method then it creates a problem.

Hi,
the real problem of the original poster seems to be <af:commandLink text="#{row.GlobalDealId}" id="cl1" action="createMDM" immediate="true" partialSubmit="true"> having immediate set to true in which case the request goes from restore view to render response. You usually use immediate=true on a command item to cancel an action (bypassing all the other JSF lifecycle steps).
Peter551059,
you don't give us much information about your case. So if the problem is IE9 and you verified IE9 is supported for the version of JDeveloper you use, then - in case you have a support contract - my best advise is to file a service request and have support looking at it just in case you hit a defect that should be filed as a bug

Any help is appreciated.
Thanks.

I'm having same issue in JDev 10.1.3.4. When I click first item in the table to go to the detail page, command link switch to display third item. This happens only after I click on the column sorting or after createInsert new record.
I used af:setActionListener for link from the table:
<af:commandLink text="#{row.UsrUserid}" action="editUser">
<af:setActionListener from="#{row.rowKeyStr}"
to="#{processScope.requestRowKey}"/>
</af:commandLink>
I got the value from the detail pagedef:
<action IterBinding="SssUsersView1Iterator" id="setCurrentRowWithKey"
InstanceName="SSSServiceAppModuleDataControl.SssUsersView1"
DataControl="SSSServiceAppModuleDataControl"
RequiresUpdateModel="false" Action="96">
<NamedData NDName="rowKey"
NDValue="#{processScope.requestRowKey}"
NDType="java.lang.String"/>
</action>
Any suggestions? Thanks.

Af:tree with command link

hi experts,
am using jdeveloper 11g version 11.1.1.5.0 - adfbc components - oracle db 10g.
am trying some examples regards,
af:tree with commandLink,
here what i did:
i achieved the af:tree with the help of some association between two tables and then i exposed in ui,
you can see in this pics1 :
http://www.4shared.com/photo/kGE2M1yl/pics1.html
and then af:tree output can also seen in pics2:
http://www.4shared.com/photo/GQTB9icb/pic2.html
this is the code for af:tree
<af:tree value="#{bindings.ApplBusFunSuiteView1.treeModel}"
                     var="node"
                     selectionListener="#{bindings.ApplBusFunSuiteView1.treeModel.makeCurrent}"
                     rowSelection="single" binding="#{backing_untitled1.t1}"
                     id="t1">
              <f:facet name="nodeStamp">
                 <af:outputText value="#{node}"
                                 binding="#{backing_untitled1.ot1}" id="ot1"/>
              </f:facet>
            </af:tree>ok thing which i did all are ok.
but my need is :
you may see in pics2.
http://www.4shared.com/photo/GQTB9icb/pic2.html
i make red mark on the on a child.
here am going to explain my need
in the picture you can see CRM as parent
MKG as first child
MKG3200 as last child.
command link should be appeared.
when i click that it will navigate to the corresponding page.
for eg: if i click MKG3200 navigate to the MKG3200 page.
how can i do this.? i need some guidance.
sorry for my poor english.

Command Link usage in JSF datatable

Hi,
Following is my requirement. Can any one help me in resolving the issue.
I hava a JSF page which displays a datatable. One of the columns in the datatable displays a command link. When the user clicks the link in a particular row. Details correpsonding to the particular row have to be displayed in another page. I am using action attribute to perform the navigation from first page to next. Inside action method in the backing, is there any other means to get the row data from the datatable for which the link is clicked.
Please help.

Command Link as a row of a datatable in JSF

Hi All,
I am new to JSF. I have a Datatable with n number of rows.
I would like to have a command Link in each of the rows, so that when i click the command link i should get the data of the entire row in my edit page.
Can anyone suggest how can i achieve this.
Regards
SN

Hi,
Do following:
1- add a datatable in your page and fill it with data comes from database(Assume u have no problem with datatable)
2- add a column as commandLink in data table. e.g.
<h:column>
<f:facet name="header">
<h:outputText value="name" />
</f:facet>
<t:commandLink action="editObject" immediate="true" >
<h:outputText value="#{theobject.name}" />
<t:updateActionListener property="#{objectForm.id}" value="#{objectDto.id}" />
</t:commandLink>
</h:column>
in this code:
"name" is header of column,
"editObject" is defined in navigation rule to navigate to edit page, lets say object form.
"theobject.name" the value that mouse gets finger over it!
"objectForm.id" the pointer to an "id setter" of a managed bean (named objectForm) defined in faces-config.xml. In this setter you can load corresponding data from database
"objectDto.id" the pointer to an "id getter" of a managed bean (named objectDto) defined in faces-config.xml. this getter return the id of the entity row you clicked on.
3- Clearly, you need to defined all managed beans, and dont forget to have a customized setter for id of objectForm (setId) to load the entity from database and fill all editable properties(as you like) in this function (setId).
4- you need a JSF page to redirect to it for editing properties and feed by objectForm
5- Thats it :)

JSF Command Button and Command Links

The main page of my JSF application has a Save button and Command Links. After making any changes on the main page the user should click Save before using any of the Links. Most of the time almost all users do this. However, some users are making changes then clicking a Link, thereby losing their changes.
I could always execute my save method in the backing bean when a link is clicked, but, most of the time this would be doing a lot of processing which usually would not be necessry.
Is their some way to check if any changes have been made and then doing the save only when necessary?

Anybody?
What would be beneficial is something like this. If somehow it could be determined if any of the JSF fields on the page were modified. Then, in the backing bean method that handles the ActionEvents for the links, I would check if changes were made and, if so, call my save method.
In other words is it possible to determine, in the backing bean, whether or not JSF fields have changed?

Command links in h:datatable not working

I have some command links in h:datatable which are not working. When I click the command link all I get is a referesh page(same page is displayed with datatable values as null). But when I put command link outside h:datatable, the navigation takes place properly. Any idea what could be worng

You can try using t:dataTable from tomahawk.jar, instead of the h:dataTable. Make the following changes in your code.
1. Add the taglib uri in your JSP as,
<%@ taglib uri = "http://myfaces.apache.org/tomahawk" prefix="t" %>
2. Add the tomahawk-1.1.3.jar to your WEB-INF/lib folder.
3. Instead of using h:dataTable, use t:dataTable.
4. After the form save your bean's state as,
</h:form>
<t:saveState id="viewForm" value="#{stateBean}"/>
Here, id can be any name and the value should be the name of your bean, how u have used in your JSP.
I hope this will help you.

Dynamic datatable and command link

I'm having a problem creating CommandLink's automatically. What we have is a tag, which can contain a set of data. We need this on several locations, so we have to create a datatable dynamically. When you press a link, it should be possible to retrieve the ID of the component on that specific row.
The problem is, we can create the table with the necessary data. When I construct the column with the ID (and the link), it fails.
Code:
HtmlCommandLink link = new HtmlCommandLink();
Application app = FacesContext.getCurrentInstance().getApplication();
ELContext elContext = FacesContext.getCurrentInstance().getELContext();
ValueExpression ve = app.getExpressionFactory().createValueExpression(elContext,"${" + TABLE_VAR_NAME + "." + property + "}", Object.class);
link.setValueExpression("value", ve);
link.getAttributes().put("rowId", ve.getExpressionString() );
link.addActionListener(
    new ActionListener(){
     public void processAction(ActionEvent arg0)
          throws AbortProcessingException {
          LOG.info(">>>>>>>>>>>>> Linked pushed !!" +
          arg0.getComponent().getAttributes().get("rowId"));
selectColumn.getChildren().add(link);
datatable.getChildren().add(selectColumn);The rowId is always #{row.code}, instead of the actual data. Is there a way to create a command link dynamically, press it and retrieve the ID of that field? That expression should be evaluated at runtime and added to the datatable, but that doesn't happen apparently.

I've read your article, but I didn't find anything I could use. Facing a deadline and don't really have time to try out multiple (possible) solutions. The problem is that all the examples I can find point to MethodBinding, but I don't need that. I just need to get the ID of the row that was clicked, nothing more.
This works fine:
link.setValueExpression("value", ve);I don't see why the other expression isn't evaluated.
I can do getParent().getParent() to get a reference to the DataTable, but the datamodel on that object is empty btw.

JSF Command Link inside DataTable has to be clicked twice in order to work
