Using command link

Hi!
I am usig jdeveloper 11.1.1.5
I had created a glm0101.jspx,cfs0010.jspx
I need to use a command link for both the jspx
say While clicking glm [command link] i need to open glm0101.jspx and by clicking trialbal [command link] i need to open cfs0010.jspx
If i am not more clear pls visit the site.,

could any body pls help me.,

if you have a navigation case between your current page and the other pages , then set the action attribute for your command button to the navigation case you defined in page flows.

Best approach to using command link from within a custom component

I have created a navigation component "Menu" , used as follows:
<custom:menu />The contents of menu are stored in an xml file and the Menu component delegates the rendering to a custom renderer, which basicaly writes out html links. (Actually, the component does a lot more, but I'm simplifying to get to the point.).
Sometimes, I need to render a command link instead of a regular html link. I don't want to re-invent the wheel here, so I want to delegate this to the standard command link components.
Approach 1: create child components within the Menu component constructor, e.g.
HtmlCommandLink c = new HtmlCommandLink();
          MethodExpression e = FacesContext.getCurrentInstance().getApplication().getExpressionFactory().
               createMethodExpression(FacesContext.getCurrentInstance().getELContext(),
               "#{registrationEditor.enterSubmission}",
               String.class,
               new Class[] { });
          c.setActionExpression(e);
          c.setValue("TestLink");
          c.setTransient(true);
          getChildren().add(c);Approach 2: delegate to the CommandLinkRenderer within my custom renderer, e.g.CommandLinkRenderer delegate = new CommandLinkRenderer();
                    HtmlCommandLink link = new HtmlCommandLink();
                    ExpressionFactory elFactory =
                         FacesContext.getCurrentInstance().getApplication().getExpressionFactory();
                    MethodExpression actionExpression =
                         elFactory.createMethodExpression(context.getELContext(), c.getExpression(), String.class, new Class[] {});
                    link.setActionExpression(actionExpression);
                    link.setParent(component.getParent());
                    link.setValue(c.getLabel());
                    delegate.encodeBegin(context, link);
                    delegate.encodeChildren(context, link);
                    delegate.encodeEnd(context, link);Is either of these a respectable approach - they feel a little hackish. If so, which do you prefer. If not, what do you recommend?
Thanks
Richard

I think either is a fine approach and not at all hackish. I prefer the second, although I couldn't tell you why (just a gut feeling). That said, I haven't tried either so there may be hidden problems. My main concern would be what happens when the request is submitted from the page, that the Restore View phase is done correctly so that the proper event is fired.

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-

Command link used as tree node

I'm using an ADF Tree where one of my nodes is a command link. I've given the link an id="myLink".
When I run the page, the tree shows up fine with just one node.
But the View Page source does not contain any entry that says id="mylink".
Where could be the problem?
Thanks
RV

Hi,
I assume you use ADF Faces RC, because otherwise you would have posted this to the JDeveloper forum. If you add a command link t a node, then this command link is used for any node that is rendered for the tree (unless you implemented it in a way that only has exactly one command link component showing in the whole tree - which I don't think you have).
In JSF you cannot have more than one component with a specific ID, which means that assigning an ID to a command link in a tree doesn't make much sense.
In ADF Faces RC, trees are active components, which means they are created in the DOM and not HTML. So using a DOM inspector like Firebug you should see your tree and link components
<a id="j_id___jsp_tag_ctru4:7:myLink" class="xdk" href="#" onclick="return false;">commandLink 1</a>

Popup window without using a command button or command link in Adf10g

Hi,
I need to show a table in a popup window on clicking in a component in the jspx page. The component can't be a command button or a command link, so i can't use 'useWindow' or 'useDialog'. What can be done in such a case. I am using Jdev version 10.1.3.
I doubt if <af:dialog> or <af:popup> components are available in ADF10g.

Hi,
There's a way, but frakly I would try to change the functional side instead of trying it. Anyhow, if you want to do it, you'll have to use a combination of autoSubmit/onclick along with DialogService.launchDialog (accessible through AdfFacesContext), but that's a very obscure part of the framework.

Using database link in my triggers,urgent

There's DB A on ServerA,DB B on ServerB.Table TA in ServerA's DB and TB on ServerB's DB.My purpose is to synchronize usera.TA with userb.TB real time.
In order to realize it,I created dblink AtoB from A to B using command "create database link AtoB.domain connect to userb identified by userb using 'BTNSname';",it's no problem for I have test on it :select count(*) from [email protected];It's ok to get the result.
But when I create trigger on table TA by using the dblink AtoB.domain to update,delete and insert datas to TB,the error "PLS-00201: identifier '[email protected]' must be declared" occurs while compiling.
The oracle version on the two servers is 8.1.7.
It happens on the production envrionment,but in our lab,there's no problem.The difference between them is that it is cluster structure in production one.
I tried several times,but failed,just wondered if some privilege was not right?But I can do selection from this dblink,only in trigger there's compilation errors.
Really hope that someone could give light on it.
Thank you in advance!
In addition,I did some modification in my triggers to have a try.
I created a synonym for the remote table,and the trigger then updates the synonym instead of the remote table [email protected] .But also failed.
The same error,saying the synonym is not declared.
Any good way to realize the same thing?

Thank you for your answering first.
I don't use replication because the destination table's structure is not exactly the same as the source one.
--The selection was done in the production,connection to the source schema,then select through the dblink from the source to the dest schema,the trigger is created in source schema on source table to handle datas in destination schema's table.In lab,all is ok,no such a problem.
--I created two dblinks,one is connect to source as system user,created a public dblink "create public database link AtoB.domain using 'BTNSname';";the other is connect as UserA,"create database link AtoB.domain connect to UserB identified by UserB using 'BTNSname';".

Command link navigation problems in IE but not firefox

Hi,
I've developed an application using JSF and SDO. I have several pages where the user is displayed data from the database and pages where the user can add data , edit data and delete data.
Each page has a jsp fragment contained in the page. This is based on faces and is the naviation menu. Each link in the menu is a command link and has navigation rules which are global. Now the problem I get is that when I sometimes nvaigate between pages using the navigation or command links in a page the page just refreshes and displays the same page again. But if I keep trying to click the link again then after a few attempts the link goes to the page i've requested. I've added system outs on the actions for the links to see if they are getting called when the page just refreshes. The answer is no as the system out line is never printed unless the action of the link is actually executed.
Now the problem is that this only occurs in ie and NOT in firefox. I'm really confused now!!
Here is some techinical details to help narrow down my situation:
I'm using wsad 5.1.2 which has faces 1.0, ie 6, firefox 1.0.3.
Any help would be appreciated!!

doh! i've solved this problem now....well for now its working perfectly but i'll have to do a bit more testing.
For anyone that has this problem here was my solution...
- In IE i went to tools > general tab > settings
from this menu choose check for newer versions of stored pages to automatically. I previously had every visit to the page.
This seems to have fixed my problem and the reason why it worked in firefox was because the settings for caching were different.

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

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 Issue

Hi,
I am using Jdevloper 11g.
I am facing issue with the following code.
In brief - I am taking Value from session and want to display those values as Command link on jspx, in af:forEach.
When I bind that Command Link with Managed Bean that time it displays Last Element only (Code given below).
When I removed Binding ( binding="#{ManagedBean.schemeName}") at that time it displays all the values on page as Command Link.
Binding is required for my app to find Link text. Is there any alternative?
<af:forEach var="item"    items="#{sessionScope.SchemeList}">
<af:commandLink text="#{item.schemeName}"
                                                id="cb14" immediate="true" partialSubmit="true"
                                                binding="#{ManagedBean.schemeName}"
                                                 inlineStyle="#{item.eligibilStatus eq 'Y' ? 'color:black' : 'color:Red'}"
                                              actionListener="#{ManagedBean.schemeChangeListener}"/>
</af:forEach>Thank You,

Hello,
Thank you,
The solution you had given that is working.
Now my issue is I have created Programmatically VO.
I refereed following link to create Programmatically VO
http://adfpractice-fedor.blogspot.com/2011/01/adf-bc-programmatically-populated-vo.html
but My issue is how to set VOs Bind Variable Value.
Because have to send that value from the bean.
In above link they took two inputText to set Bind Variable value but in my condition I cannot take InputText.
I am setting that value in my Managed bean as shown below.
public void schemeChangeListener(ActionEvent actionEvent) {
      OperationBinding opBinding =
          CommonUtil.getOperationBinding("#{bindings}",
                                         "initParamValues");
      opBinding.getParamsMap().put("custID", customerID.getValue().toString());
      opBinding.getParamsMap().put("accountType", (CommonUtil.evaluateEL("#{bindings.ADAccountType.attributeValue}")).toString());
      opBinding.getParamsMap().put("productID", (CommonUtil.evaluateEL("#{bindings.DMAProductId.attributeValue}")).toString());
      opBinding.getParamsMap().put("entityID", homeEntityID);
      opBinding.getParamsMap().put("schemeCode", linkText);
      opBinding.execute();
}and I have taken that VO as Table on jspx page.
Issue is before going to bean method it goes to View object and show NullPointerException because the values never get set.
The above code is called when the commandLink is clicked code given below.
<af:commandLink text="#{item.schemeName}"
                                              id="sName" immediate="true" partialSubmit="true"
                                              inlineStyle="#{item.eligibilStatus eq 'Y' ? 'color:black' : 'color:Red'}"
                                              actionListener="#{MakBean.schemeChangeListener}"/>is there any solution how can I set the Bind Variable value from bean and get Expected result in table.
Thank you

Command Link : Backing bean setters/getters always invoked

I am trying to understand how to the setters and getters of a request scope managed backing bean are invoked through the navigation flow when using a command link.
It seems that no matter where the navigation rules redirects the page as a result of the action, both the setters and getters of any field bound in the originating page are called.
For example if the originating page has a field name referred by "#{UserBean.name}" to input a username. setName() and getName() are always called as a result of a click on a command link
This behavior is easily seen in a simple JSF example such as http://www.netbeans.org/kb/articles/jAstrologer-intro.html.
If the jsp pointed by "to-view-id" is changed to have no reference to the backing bean or is changed to a jsp with just text, both setters and getters are still invoked.
I could understand why the setters would be invoked (doesn't know ahead of time if the bean will be used?) but at least why the getters?
Last, how to prevent this behavior? The problem is that the backing bean might have complex logic where it will fetch data if a getter is called.
Thanks.

I guess this article might be interesting to get some insights http://balusc.xs4all.nl/srv/dev-jep-djl.html
The setters are invoked to set values and the getters are invoked to get the eventually presetted default values or the previously submitted values.

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.

Command Link attribute is returning null.

Hi all,
I have a pojo iterator with me. I have to generate command link for a attribute from that iterator. I generated them using a ForEach loop as below and put address of employee as an attribute of that tag. Now in the Action Listener i am fetching this attribute using actionEvent as below : -
    public void displayUploadAttachment(ActionEvent actionEvent) {
       System.out.println("Content Id:- "+actionEvent.getComponent().getAttributes().get("adr"));
My action Listener returns it as NULL. I am not getting why it is doing this.
<af:forEach items="#{bindings.myEmpIterator.children}"
                              var="emp">
                    <af:commandLink text="#{emp.firstName}" partialSubmit="true" id="cl22"
                                    actionListener="#{viewScope.empBean.displayEmpAddress}">
                    <f:attribute name="adr" value="#{emp.address}"/>
                    </af:commandLink>
                  </af:forEach>
J dev version
Studio Edition Version 11.1.1.6.0

Hi,
Couple of things to check.
1. Check if the address is really null (instead of #{emp.firstName} as text for the commandLink, try with #{emp.address}).
2. Instead of
System.out.println("Content Id:- "+actionEvent.getComponent().getAttributes().get("adr"));
try
System.out.println("Content Id:- "+((RichCommandLink)actionEvent.getSource()).getAttributes().get("adr"));
