On Command Link Action is not Firing

Hi
I am using JDev Version 11.1.1.6
I have command link where i wrote a method in bean for Action. And the same command link has the showpopup behaviour
My assumption was on click of command link Action method fires first then showpopup behaviour fires next.
But when i click on command link action method is not firing, only showpopup behaviour is firing .
is it expected behaviour?
Many Thanks,
~Jagadeesh Badri

Hi Jagadeesh
Yes, it is an expected behaviour. The documentation about af:showPopUpBehaviour says that:
The showPopupBehavior tag cancels the client event defined by the triggerType. Canceling the client event will prevent delivery to the server. This is significant for action events raised by command family components because the server-side action listeners will be ignored. All actionListener method bindings and associated action listeners will not be invoked when the triggerType of "action" is used.
This means that if you use the triggertype of action, then your action method in the link will be ignored. Maybe if you change the triggerType to 'Click' you will get your actionListener triggered and the popup showed.

Actions do not fired inside af:table

Hi,
I have recently faced a problem within actions inside af:table. Such that: The action of a commanlink (the command link resides in a af:table column) does not executed (the backing bean do not get hit). The suprising thing is: The command can be executed outside af:table. I do not get any error or warning.
I will be apprecitated if you provide help.... The list the table I hope it will also provide help... The command link actions do not provoked (both of them).

Hi,
more likely is that the table is not enclosed by a form tag. Forget about what the previous poster said about the token, it doesn't hold true in your case

Command link action not being called

Hi,
I raised another bug about this and I thought I had fixed this but it seems to have come back again! Here are the details:
The Problem
- I have a jsf application that uses SDO to manage database calls/changes. In the application I have a navigation menu which consists of command links. From time to time (doesn't always happen) you click on a link and the page just refreshes and you are not taken to the requested page. Now this doesn't happen all the time! I've looked at logs and added debugs but I can't find anything apart from the face that when the page just refreshes the action behind the command link is not called.
Has anyone experienced this before? I'm using wsad 5.1.2 and have this problem and the version of faces is 1.0.
Please help as I have no idea what is causing this!!

yep, sorry for reposting but in that post I said I had it fixed but obviously its not. What's really change is that I cant recreate this problem on my laptop but on our dev and test environments this problem still exists. My initial thoughts is that this is an environment problem but i'm not totally convinced as the was settings etc are the same as on my laptop.

Delaying the command link action till user presses Yes/No in dialog

Hi ,
On a command link in an af:table i am trying to display and Yes/No Dialog box. On clicking the link, the action binded with the link gets executed first and then the dialog gets initialized. Can we some how deffer the link execution till the user presses Yes/NO?
following is the code
=======================================================================
<af:column id="c13" headerText="Lock">
<af:commandLink
text="lockUser"
disabled="#{!bindings.lockUser.enabled}"
id="cl1"
action="#{searchBean.lockUser}"
partialSubmit="true"
partialTriggers="cl1" >
<af:showPopupBehavior popupId="::p1"
triggerType="click"/>
</af:commandLink>
</af:column>
=======================================================================
<af:popup id="p1" partialTriggers="p1">
<af:dialog id="d2" dialogListener="#{searchBean.dialogListener}"
partialTriggers="d2" title="xcx" type="okCancel"/>
</af:popup>
=======================================================================
public String lockUser() {
BindingContainer bindings = getBindings();
OperationBinding operationBinding = bindings.getOperationBinding("lockUser");
Object result = operationBinding.execute();
System.out.println("***111");
if (!operationBinding.getErrors().isEmpty()) {
return null;
searchUser();
return null;
=======================================================================
public void dialogListener(DialogEvent dialogEvent)
String ss="HHH";
System.out.println(ss);
if (dialogEvent.getOutcome().equals(DialogEvent.Outcome.ok))
lockUser();
System.out.println("SAVE your work here");
}else
System.out.println("Do Not Do Any Thing");
=======================================================================

This should be possible, if you remove the action from the af:commandLink and execute the action in the dialoglistener
    public void dialogListener(DialogEvent dialogEvent)
        Outcome lOutcome = dialogEvent.getOutcome();
        if (lOutcome.equals(Outcome.ok))
            // do the navigation
            ControllerContext ccontext = ControllerContext.getInstance();
            //set the viewId – the name of the view activity to
            //go to - to display
            String viewId = "Emp";
            ccontext.getCurrentViewPort().setViewId(viewId);
            // or execute a method....
    }Timo

Command link action

I am using a commandlink with an action that returns a value for navigation. The action fires every other time I click the link.
Here is my tag:
<h:commandLink
id="customer"
action="#{navigateBean.customerSelected}"
target="content">
<f:verbatim>
<P>1. Customer</P>
</f:verbatim>
</h:commandLink>Any thoughts?
Thanks!
Ted

The target attribute seemed to work, but I couldn't get around the action firing every other click. I ended up doing away with frame navigation and used the panelNavigation tag from MyFaces wrapped in a facet tag. Must be a frame issue.

Command link / button action is not taking place if i use it in iterator.

Hi,
I am new to ADF, i am facing 1 issue while implementing ADF mobile browser application.
Issue: command link / button action is not taking place if i use it in iterator. its just refreshing the page it self and displaying as no records.
Scenario is i am populating the search results in results page from search page using iterator, i want to get the complete details in different page (results page -> details page) .
I have tried in different ways.like
case1:
<tr:panelGroupLayout id="pgl2" layout="vertical" styleClass="af_m_panelBase">
<tr:panelHeader text="#{classviewBundle.SEARCH_RESULTS}" id="ph1"/>
<tr:iterator id="i1" value="#{bindings.SubjectVO1.collectionModel}" var="subject"
varStatus="subIndx" rows="100">
<tr:panelBox text="#{subject.Subject} #{subject.CatalogNbr} - #{subject.CourseTitleLong}"
styleClass="af_m_listingPrimaryDetails" id="pb1">
<f:facet name="toolbar"/>
<tr:table var="ssrClass" rowBandingInterval="1" id="t1" value="#{subject.children}"
varStatus="clsIndx" rowSelection="none"
binding="#{SessionBean.subjectTable}" verticalGridVisible="true"
emptyText="No Records" width="100%">
<tr:column id="c9" sortable="false" styleClass="width:100%">
<*tr:commandLink text="Section: #{ssrClass.ClassSection}-#{ssrClass.SsrComponentLovDescr} (#{ssrClass.ClassNbr})"*
id="commandLink2" styleClass="af_m_listingLink"
*action="#{pageFlowScope.BackingBean.searchaction}"></tr:commandLink>*
//remaining code
in this case commandlink action is not able to invoke serachaction() method
case 2:
<tr:commandLink text="Section: #{ssrClass.ClassSection}-#{ssrClass.SsrComponentLovDescr} (#{ssrClass.ClassNbr})"
id="commandLink2" styleClass="af_m_listingLink"
action="classdetails}"></tr:commandLink>
in this case its not able to navigate to classdetails page.
I gave correct navigation cases and rules in taskflow,but its working fine when the command link is out of iterator only.
i tried with actionlistener too.. but no use.. please help me out of this problem .
*Update to issue:*
The actual issue is when i use command link/button in an table/iterator whose parent tag is another iterator then the action is not taking place.
the structer of my code is
< iterator1>
#command link action1
< iterator2>
#command link action2
</ iterator2>
< /iterator1>
#command link action1 is working but "#command link action2" is not...
Thanks

Hi,
To solve my problem I used a af:foreach instead.
<af:forEach items="#{viewScope.DataBySubjectServiceBean.toArray}" var="text">
<af:commandLink text="#{text.IndTextEn}" action="indicator-selected" id="cl1">
<af:setActionListener from="#{text.IndCode}" to="#{pageFlowScope.IndicatorCodeParam}" />
</af:commandLink>
</af:forEach>
By the way you need to convert the iterator to an Array using a ManagedBean.
public Object[] toArray() {
CollectionModel cm = (CollectionModel) getEL("#{bindings.TView1.collectionModel}");
indicators = new Object[cm.getRowCount()];
for(int i=0;i<cm.getRowCount();i++){
indicators[i] = cm.getRowData(i);
return indicators;
public static Object getEL(String expr) {
FacesContext fc = FacesContext.getCurrentInstance();
return fc.getApplication().evaluateExpressionGet(fc,expr,Object.class);
Hope that helps-

h:CommandLink : Action event not called on the first click

Hi,
I am facing a problem here.
I have a JSF page:
When I first load the page, I have few text boxes and dropdowns. With out doing anything If I click the <h:commandLink I call an action in my pagecode.
But the problem is on the very first load of the page, without doing anything if I click on the command link action event in my pagecode is not called, but If I click on the link the second timethe pagecode actionevent is called.
So I think tried submitting the form in the JSF page onclik of the commandlink it works in my Local IBM RAD. But doesnot work in the WebSphere Portal.
So can you tell me if I can submit the form atleast once when the page loads for the first time
This is my command link:
<tr>
<td colspan="2" align="center">
<h:commandLink styleClass="commandLink" id="lnkBtnCreateUser" action="#{pc_Createuser.doLnkBtnCreateUserAction}">
<hx:graphicImageEx styleClass="graphicImageEx" id="imgBtnCreateUser" value="/theme/images/btnCreateUser.gif" style="border:0;cursor:pointer" onclick="return onFormSubmit();"></hx:graphicImageEx>
</h:commandLink>
</td>
</tr>
function onFormSubmit(){
//enabling all the disable components
So can anybody please help me on this. Why exactly the pageCode action event is not called for the very first click ???

seems that a prependID="false" attribute in the respective form was causing the trouble. At least it's working now that I've deleted it.
I introduced it, because last time the component ID's messed up the output of the error/success messages ("j_id:xxx isn't that of a usefull information to the enduser).

My command link doesn't work

hi all,
i have a created a page where i am performing a web type search with search form and search results on the same page and i have also implemented the conditional display of search results table as directed by the ADFBC guide.
i.e., I created a managed bean where in am setting the searchFirstTime flag. here is the code of my managed bean.
public class UserState {
private static final String SEARCH_FIRSTTIME_FLAG = "SEARCH_FIRSTTIME_FLAG";
private HashMap hmUserSettings = new HashMap();
public UserState() {
try{
System.out.println("setting the user settings in constructor");
hmUserSettings.put(SEARCH_FIRSTTIME_FLAG,true);
}catch(Exception e){
e.printStackTrace();
public boolean isSearchFirstTime(){
Boolean firstTime = (Boolean)hmUserSettings.get(SEARCH_FIRSTTIME_FLAG);
try{
System.out.println("setting the search flag in isSearchFirstTime firstTime.booleanValue() :"+firstTime.booleanValue());
if (firstTime == null){
firstTime = true;
}catch(Exception e){
e.printStackTrace();
return firstTime.booleanValue();
public void setSearchFirstTime(boolean searchFlag){
try{
System.out.println("setting the search flag searchFlag :"+searchFlag);
hmUserSettings.put(SEARCH_FIRSTTIME_FLAG, new Boolean(searchFlag));
}catch(Exception e){
e.printStackTrace();
In the search results table one of the columns is a command link, clicking on which opens a pop up window where i have some more details being displayed.
here is the code of my jspx page for the command link
<af:commandLink text="#{row.OrderNumber}"
binding="#{backing_TestDDPUD.commandLink1}"
action="#{backing_TestDDPUD.commandLink1_action}"
useWindow="true"
partialSubmit="true"
windowHeight="200"
windowWidth="500"
id="commandLink1"/>
i have specified the action to be performed,in the backing bean of my page, here's the code
public String commandLink1_action() {
BindingContainer bindings = getBindings();
OperationBinding operationBinding =
bindings.getOperationBinding("setCurrentRowWithKey");
Object result = operationBinding.execute();
System.out.println("inside commandLink1_action");
if (!operationBinding.getErrors().isEmpty()) {
System.out.println("$$$$$$$$$$$$$$$ has errors $$$$$$$$$$$$4");
return null;
DCIteratorBinding ib = (DCIteratorBinding)bindings.get("OeOrderHeadersViewResultsIterator");
Row row = ib.getCurrentRow();
Number numHeaderId = (Number)row.getAttribute("HeaderId");
FacesContext fc = FacesContext.getCurrentInstance();
// 2. Create value binding for the #{data} EL expression
ValueBinding vb = fc.getApplication().createValueBinding("#{data}");
// 3. Evaluate the value binding, casting the result to BindingContext
BindingContext bc = (BindingContext)vb.getValue(fc);
// 4. Find the data control by name from the binding context
DCDataControl dc = bc.findDataControl("TestDDAppModuleDataControl");
// 5. Access the application module data provider
ApplicationModule am = (ApplicationModule)dc.getDataProvider();
ViewObject vo = am.findViewObject("OeOrderLinesAllView");
vo.setNamedWhereClauseParam("theHeaderId",numHeaderId);
System.out.println((vo.getNamedWhereClauseParam("theHeaderId")));
return "dialog:orderDetails";
my problem is that now when i enter a search criteria and execute the search, the search results are displayed properly in the table but when i click on the command link it does not open the pop up window, it does not even enter into the commandlink1_action() method..here's the log which i get after i click on the command link..can somebody please tell me what is going wrong or what exactly is happening

hi Frank,
i have my table inside a panel page which is already sorrounded with h:form so i cannot sorround my table again with h:form or af:form. the command link in the page was working fine, till i included the code for the conditional display of the results table. If i look at the log printed after i click on the command link, i don't see any of the sop's being printed that i have given inside the commandlink1_action() method, i have a feeling that my action method is not being called at all and i am not able to figure out why the sop in the isSearchFirstTime() method is being printed 4 times.

ADF Tree Command Link + Content Menu

Hi,
I am trying to build a tree, in which the nodes should have a command link and a context menu enabled. Using JDeveloper 11.1.1.6.0, however the context menu is not showing up, if the command link is enable for a particular node. If the command link option is not set for a node, then the menu option does shows up. Below is what my code looks like. Has anyone faced a similar issue/know of a solution?
My Code is something like -
*<f:facet name="contextMenu">*
<af:popup id="p1" contentDelivery="lazyUncached">
<af:menu text="Location Menu" id="m31"
visible="#{pageFlowScope.TreeData.showLocationMenu}" contentDelivery="immediate">
<af:commandMenuItem text="Add new Department"
id="cmi2" partialSubmit="true" immediate="true"
actionListener="#{pageFlowScope.TreeData.createDepartment}">
<af:setPropertyListener from="#{node.viewType}"
to="#{pageFlowScope.formView}"
type="action"/>
<f:attribute name="node" value="#{node}"/>
</af:commandMenuItem>
</af:menu>
</facet>
<f:facet name="nodeStamp">
*<af:commandLink text="#{node.key} #{node.text}"*
*action="#{pageFlowScope.DynamicRegionBean.getDep}" id="cl1" partialSubmit="true" immediate="true"/>*
*</f:facet>*

Hi Timo,
Yeah... adding an output text, shows the context menu on the text, however I was looking for something like one 'text' rendered and it doing the option of both.
Something like what we can do for any hyper link, if click on it, it opens that link or else if I right click on the link, it gives me options like - Open in new Tab/Window etc.
Any suggestions??
Thanks

Resetting the id of dynamically generated JSF custom command link

I have a java faces page which displays data from an arraylist.
This list is populated when user inputs data in the input text field and clicks "Add Group" button.
The arralylist consist of another arraylist within the former.
I have created a custom command link for the former arraylist.
As an user can add data to the arraylist so can he remove it from the arraylist.
The command link has a method binding "closeTask" which is invoked when command link is clicked.
This action removes the clicked element from the arraylist and displays the fresh list.
The key field from the bean in the former arraylist is set in request, and is retrieved in the "closeTask" method to be assigned to the command link output text id (i.e. it identifies the element that is to be deleted from the arraylist).
This functionality does not work as expected, i.e. command link component is not created/rendered during deletion as it is created while addition.
As a result eventhough the element is removed from the arraylist, the id corresponding to the fresh arraylist is not refreshed and for further actions correct id is not passed and the deletion function does not work.
How can I have resolve this problem?
The sample code is included.
Thanks in advance.

You cud define jsObjectNeeded and onClientClick properties for the htlm component and catch the event to find itz ID.

Command link usage.

Hi,
I am using </h:commandLink > tag to generate command links in each row of <h:table> tag. simple code i am using:
<h:dataTable value="#{projectBean.projects}" var="projectsData">
<h:column>
<f:facet name="header">Name</f:facet>
<h:outputLink value="#{projectBean.getProjectDetails">
<h:outputText value="#{projectsData.name}"/>
<f:param name="pId" value="#{projectsData.projectId}"/>
</h:outputLink>
</h:column>
<h:column>
<f:facet name="header">Date</f:facet>
<h:outputText value="#{projectsData.stDate"/>
</h:column>
</h:table>
I am able to generat the link with the param value passing but the action method is not getting invoked on press of the link, could any one help me in usage of commandlink tag in invoking action page.
Regards
Mruthyunjaya

I have used the command link instead of outLink also the tag is under form tag only but still the link action is not executed.
if i changed the bean to session scope it is running fine, but as the bean is session scope it is displaying old values along with new values, i.e. the form is displayed with repeated values.
can some one help me in solving this problem.
thanks

Pagination issue with Command Link

Hi
I have a HtmlDatatable in which I am I am using pagination. Pagination is working fine the issue is one colum has been used with commnadlink.
Whne I use the pagination(Say when I click next or last) i am not getting the hyper link in that column.
Any idea?
Thanks in advance

Hi,
hard to say. Looks as if the browser blocks the command link when the note window launches as modal dialogs would do. There are two reasons for this IMO
1. The hover code also executes when you want to click the link, which means that you don#t get to executing your action. Work around is to detect whether the note window is open and if don't try and re-launch the note window
2. If you use showPopupBehavior to launch the note window, then this actually kills all action listener methods (which then may be a second reason). So my suggestion is to try and launch the hover popup from JavaScript using an af:clientListener
Sample code: Sameh Nassar: JavaScript With ADF Faces Samples
the client listener should listen for the mouse over event.
If none of this help and you have access to customer support, I suggest to create a test case and file a service request. My current guess though is that the reason for the behavior is in in your code (browsers tend to work differently in the way they execute JS events too).

Issue with command link in chrome/mozilla

Hi All,
I have designed a simple jspx page having a command link component.
This command link component is tied up with two sets of operations associated with it -
> Displays a note window using hover action.
> Launched a popup on clicking the link components.
While performing some test runs on different browsers, I noticed different behavioural pattern -
> Internet Explorer - Placing the cursor on link displays the note window and the command link remains enabled for the user to click on it and launch the popup.
> Mozilla/Chrome - Placing the cursor on the link displays the note window, however, on the clicking the link, the popup doesn't launch. The user has to move and place the cursor again on the link to perform the desired event.
Request your guidance on troubleshooting the problem.
I am using JDeveloper version 11.1.1.7.

Ankit Gupta
