Calling Action listener in Custom component

Hello,
I am currently developing my own component containing an hyper-link and I am stuck with the Renderer. What should I put in the href of my "a" tag (<a href="???">) in order to call an Action listener ? I would like my renderer to do something similar to <h:commandLink actionListener="#{myBean.myActionListener}".
Could you help me?
Gerald.</a>

Hello,
Did you achieve this??? I'm also planing to put very similar to your thought. If you have a solution on your requirement, pls mail me to [email protected]
Thanks in Advance.
regards,
Ram

Calling action listener for a BUTTON component in java bean page

Hi,
I have made it like this.
public void handleButtonPressed(ActionEvent event){
System.out.println("success!!!!!");
//code for calling actionlistener
FacesContext fctx = FacesContext.getCurrentInstance();
ELContext elctx = fctx.getELContext();
Application application = fctx.getApplication();
ExpressionFactory exprFactory = application.getExpressionFactory();
MethodExpression methodExpr = null;
methodExpr = exprFactory.createMethodExpression(elctx, "#{exbean.handleButtonPressed}",null,new Class[] { ActionEvent.class });
MethodExpressionActionListener actionListener = null;
actionListener = new MethodExpressionActionListener(methodExpr);
button.addActionListener(actionListener);
Even after making the listener Function as Void wHen i click the button i m getting the error saying."ARGUMENTS MISMATCH,ADF_FACES60097"??
can you help me out?
and in the msg log i m getting this
"SkinFactoryImpl> <getSkin> Cannot find a skin that matches family portal and version v1.1. We will use the skin portal.desktop.
<MethodExpressionActionListener> <processAction> Received 'javax.el.PropertyNotFoundException' when invoking action listener '#{exbean.handleButtonPressed}' for component 'null'
<MethodExpressionActionListener> <processAction> javax.el.PropertyNotFoundException: Target Unreachable, identifier 'custombean' resolved to null"
I Have tried with this giving Void TYPE as an argument
methodExpr = exprFactory.createMethodExpression(elctx, "#{exbean.handleButtonPressed},Void.TYPE,new Class[] { ActionEvent.class });
I M getting the same error.

yeah but i m creating button itself dynamically by java code....
//code
UIComponent button;
button = findComponentInRoot("cb1");
RichPanelGroupLayout pgl;
pgl = (RichPanelGroupLayout)button.getParent();
List<UIComponent> children;
children = pgl.getChildren();
RichPanelGroupLayout pgll;
pgll = new RichPanelGroupLayout();
RichInputText it;
it = new RichInputText();
it.setLabel("New textbox " + (children.size()));
RichCommandButton but = new RichCommandButton();
but.setPartialSubmit(true);
but.setText("Delete");
/*calling actionevent*/
FacesContext fctx = FacesContext.getCurrentInstance();
ELContext elctx = fctx.getELContext();
Application application = fctx.getApplication();
ExpressionFactory exprFactory = application.getExpressionFactory();
MethodExpression methodExpr = null;
methodExpr = exprFactory.createMethodExpression( elctx,"#{inbean.actionPerformed}",null, new Class[] {ActionEvent.class});
MethodExpressionActionListener actionListener = null;
actionListener = new MethodExpressionActionListener(methodExpr);
but.addActionListener(actionListener);
/*end of call*/
children.add(pgll);
children.add(it);
children.add(but);
AdfFacesContext.getCurrentInstance().addPartialTarget(pgl);
//code to call method
public void actionPerformed(ActionEvent event) {
System.out.println("entered sec bean");
return " ";}
this way i m trying to create a button programatically and tryin to add actionlistener which is not working.
the actionlistener is throwing error.... with the line
methodExpr = exprFactory.createMethodExpression( elctx,"#{inbean.actionPerformed}",null, new Class[] {ActionEvent.class});

Error when calling bpm service from custom component

Hi all,
I have built a custom component in order to fetch task related data by calling a bpm service inside the method of my custom service.
This is the error trace i got in audit info.
"not loading page MSG_PAGE because it is up to date with timestamp 1324331008000
Script stack dump (user: abc, request: IdcService=CUSTOM_SERVICE&dDocName=ABC018005)
No resource include or function stack for error. "
What does this error signify?
In the service definition of my custom service, I am using MSG_PAGE as my template. Is it related to this why i am facing the error? how do i get to know for a particular functionality i should use a particular template?
Please provide your inputs asap.
Thanks in advance.

HI jiri,
Please have a look at the stacktrace and provide me a solution as in how to overcome the error.
I had included Report.trace in order to check the flow of the program and found that the problem arises when i establish the connection.

Missing Action Event from Custom Component

Hi JSF Gurus,
I have two custom components, both extends UICommand and have their
own renderers. I use them on two seperate pages, say component1 on
page1 and component2 on page2. And page2 is include inside page2.
I registered an action listener on component2. When the composite page
is rendered, I clicked on component2. However, the registered action
listener was not invoked. Inside the debugging (I'm using IntelliJ
IDEA 5.0) I set a breakpoint inside the decode method of Renderer2
(renderer for component2). I do see the componen2 actually as an
actionLister method binding being set to correct value. I do queue the
new action event to component2 at the end of the decode method. But
the action listerner never invoke.
Any idea what did I miss?
Thanks,
Edmond

Hi Yuki,
Yeah, after I turn on detail JSF debugging as instructed by the book Core JavaServer Faces, I figured out I had a validation error. That solves the mystery.
Thanks,
Edmond

Stellent UCM :: calling javascript inside the custom component

Hi Experts,
I am new to the stellent content server (Oracle content server). Currently we are working on the project which needs to be integrated with the content server for the content selection. I did some prototype to pass back the selection value to the parent window using the javascript window.opener.<parent java script> from a dummy page. Now i am customizing the content server custom component. Unfortunately i cannot be able to call back the parent javascript from the custom component. Seems the window.opener is null.
I have tried with windowUtils.getOpener() method which is available in the content server weblayout. Still i could not be able to call back.
Guys i am looking forward your idea ? If anyone knows the way to resolve this issue or any other best suitable way to handle this please ping me back.
Regards Thiva

How to Call action Listener from Mouse Listener event

One class (class 1)implements mouse listener and responds to a mouse events.
As part of that response it needs to call a variable set method in another class (class 2)and also have that setMethod call it's own ActionPerformed.
Seems the problem is I don't have aaction event to pass
I only have a mouse event. As follows:
class 1
public void mousePressed(MouseEvent e) {
int y1=Math.abs(e.getY()-y);
this.sourceReference.setVar(y1);
repaint();
class 2
int var;
public void setVar(int y)
var=y;
this.ActionPerformed(?? ); //This is what I want to do
Same question slightly different.
From class 1 I scould first call the setVar method
and then issue a call to class 2's ActionPerformed.
But again I don't seem to have the proper action event e to pass it.
Thanks

Do you need any information from an ActionEvent that you'd be calling from the MouseEvent (ie the action command, or somethig) or can you just have the actionPerformed method just call a different method that doesn't need an ActionEvent?
public void actionPerformed(ActionEvent e) {
this.doActionStuff();
public void doActionStuff() {
// does what you want the action event to do
Then from the mousePressed method you can just call the doActionStuff method.
I'm not sure if this helps or not, hope it does.

Decode function not called for a custom component

I know this problem happened in the past - in the EA2, EA4 and I believe the beta version as well, but does anyone know if it has been solved for the release ?
In short - I'm working with the release, created a menuBar component and the decode method in the renderer is not called after I submit the page. In the past, there were rumors that this happened due to relative paths in the JSP (for js files, images, etc.).
Does anyone else have this problem ? or better , know how to solve it ?
Thanx,
Netta.

It's not that simple - The component is getting rendered, all the encode methods are called and the decode is called also , but only the first time the form is submitted.
I added this custom component to the guessNumber application, and I have a menuBar in the greeting.jsp that leads to the response.jsp and vice versa. it looks like this in the greeting.jsp page -

<t:MenuBar id="bar1" styleClass="myClass" >
<t:Menu id="menu1" name="menu1">
<t:Menu id="menu2" name="menu2">
<t:MenuItem id="item2_1" name="item2_1" action="/mytest/guess/response.jsp"/>
<t:MenuItem id="item2_2" name="item2_2" action="http://www.msn.com"/>
<t:Menu id="menu3" name="menu3">
<t:MenuItem id="item3_1" name="item3_1x" action="http://www.msn.com"/>
</t:Menu>
</t:Menu>
</t:Menu>
<t:MenuItem id="item3" name="item3" action="http://www.cnn.com"/>
</t:MenuBar>

In the response it looks like this -

<t:MenuBar id="bar2" styleClass="myClass" >
<t:MenuItem id="item3" name="item3" action="/mytest/guess/greeting.jsp"/>
</t:MenuBar>

and every time a menuItem is clicked on, the JS calls submit form.
Since the menus are rendered, I assume there's nothing wrong with the rendererType and any other renderer problem. Since the decode is called only once, I assume the right form is being submitted.
So, what can cause it to stop calling the decode ???
Could it be that becase I go directly to the page and not through the navigation rules ( I call window.open directly from the JS), it creates a problem ??
Please help, I've been wasting so much time on this !
Netta.

Custom button with action listener - will not invoke action listener

Hi
For whatever reason, I cannot find a concise example of a simple custom component that can invoke an action listener. The tutorials I've read so far either ignore this fundamental topic or only make the slightest make reference to it.
The best I have come up with - in terms of a simple prototype is below... but, the action listener is never invoked.... Can someone tell me what I am missing (full code below). Hopefully, what is missing or incorrect will be obvious to you JSF experts out there.
Thanks for any help!!

got it working....
The changes were:
in "SpecialBtnRenderer"...
--new--
                    mb.invoke(context, new Object[1]);
--old--
                    mb.invoke(context, new Object[0]);
in "SpecialBtnTag"...
--new--
import javax.faces.event.ActionEvent;
--new--
                MethodBinding mb = FacesContext.getCurrentInstance().getApplication().createMethodBinding(specialBtnListener, new Class[]{ActionEvent.class});
--old--
                MethodBinding mb = FacesContext.getCurrentInstance().getApplication().createMethodBinding(specialBtnListener, null);
-Below is the entire application, again -- for those (like myself) who need concrete examples...
I hope this helps someone else! --f

Custom component calling function from main.mxml

I have a main.mxml that has the following function in it:
public function SubChooseField(evt:Event):void{
Alert.show( "Sub has been chosen" );
main.mxml also places the following custom component:
<?xml version="1.0" encoding="utf-8"?>
<mx:ComboBox xmlns:mx="
http://www.adobe.com/2006/mxml"
width="180" close="parent.SubChooseField(event)">
<mx:dataProvider>
<mx:Object data="1" label="choice 1 />
<mx:Object data="2" label="choice 2" />
<mx:Object data="3" label="choice 3" />
</mx:dataProvider>
</mx:ComboBox>
I want it so that when you chose one of the options in the
comboBox, it will call the function SubChooseField in the
main.mxml. But when I compile this, no matter what i try, i get the
error:
Error: Call to a possibly undefined method SubChooseField
through a reference with static type my_custom_opponent.
OR if i change the codeand remove the 'parent' to say:
close="SubChooseField(event)"> i get error:
Error: Call to a possibly undefined method SubChooseField.
any help much appreciated.

Rather than trying to use parent, using events might help
here. In your main mxml file, just listen for the change event that
is dispatched from your custom component. Since it is a ComboBox
component, it automatically dispatches this event. If your
component was more complex, you would need to dispatch a custom
event.
If your custom component was named CustomCombo, then the mxml
in your main file would look something like this:
<ns1:CustomCombo id="cb" x="70" y="39" width="160"
change="SubChooseField(event)"/>

Transient form component and action listener

Hi,
I am binding a transient component to my h:form and wonder why my action listener is not called when update the form. Could someone give me a hint if this is possible? Are transient forms ignoring action listeners? Can some one give my a short example?
Maciek

The actionlistener can do whatever you want. Not sure what you need exactly but it might be better idea to create some Action classes and use them on each button:

Decode-method for custom component isn't called

Hi,
i have writen a custom component which gets some information by command-link. To make the data from the link accessible, i wrote a decode method in my renderer and in me component. But both method are not called from the faces framework.
Dows anybody knows what i made wrong???
Thanks, Sebastian

Hi,
thank you for your reply.
Unfortunately the processDecodes(...) of my component is also not called from the framework. Does anybody knows what i'm making wrong???
Thanks!

How a custom component is called when we install a custom component in UCM.

How a custom component is called when we install a custom component in UCM.
On what event the component services will be activated and called.
Suppose i create a Custom service name MULTIPLECHECKIN then this service will be called on what event and where it will be defined to call.

Saurabh,
the code is packed in the component (see component\Security Filter\java\Security Filter\ModifyAttributesFilter.java - the first Security Filter is the component name, the other Security Filter is the Java package name).
What is important:
- your class must implement the FilterImplementor interface (you will need UCM standard classes - server.zip in your classpath) and its doFilter method
How the filter is executed?
- actually, in this case you don't need any new service - you can use the standard 'hook', which is provided by standard checkin services
- in Component Wizard create a new component, add your compiled class to it (make sure you follow the rules not to end up in classpath issues)
- in Component Wizard click the 'Java Code' tab. Here you can add a Custom filter called validateCheckinData, which is executed by standard checkin services. If you parametrize the filter to call your class created above, you are done.
'Working with Content Components' manual (e.g. here: http://download.oracle.com/docs/cd/E10316_01/cs/cs_doc_10/documentation/developer/using_components_10en.pdf) can give you a basic picture. A better resource is Bex Huff's book - I would recommend you to get it, because it has a step-by-step HelloWorld example which can guide you through Component Wizard. I could also send you my own component (send me an email at [email protected]) which implements a filter for user quotas, so you just need to "replace classes".
As for the other half of your task, searching for the file in the database server will work only if you use database as your storage (ie. install and configure File Store Provider component accordingly). Of course, you could do a search for file in this case - just consider that you will be comparing two BLOBs rather than two relatively short check-sums (most likely strings or arrays of bytes). Besides, it will not work if you use filesystem as your storage.

Action Listener Method called multiple times

I have a page (fragment .jsff), containing a simple input text and a button called "search". When I click on "Search" the action listener is triggered multiple times. (The results are displayed in a table inside a panel collection).
The results are actually coming back ok.
When I debug the code, I can see the action listener method called twice.
Do you know why is that?
What should I be taking care of?
This is my code :
*** Fragment ****
<af:commandButton text="#{identityBundle.search_label}" id="cb1"
actionListener="#{UserDetailsBean.searchUsersListener}"
disabled="#{!bindings.searchUsers.enabled}"/>
*** Managed bean ***
public void searchUsersListener(ActionEvent actionEvent) {
// Add event code here...
DCBindingContainer bindings = (DCBindingContainer)getBindings();
DCIteratorBinding iter = bindings.findIteratorBinding("userIterator");
DCDataRow row = (DCDataRow)iter.getCurrentRow();
User user = (User)row.getDataProvider();
boolean isSearchCriteriaPresent = false;
if(user != null){
String fn = user.getFirstname();
if(fn != null && !fn.trim().equals("")){
isSearchCriteriaPresent = true;
user.setLastname(fn);
user.setNonMTUserLogin(fn);
try {
Map <Object, Object> userMap = PropertyUtils.describe(user);
for(Map.Entry<Object, Object> entry: userMap.entrySet()){
if(entry.getKey() != null && entry.getValue() != null && !entry.getKey().toString().equalsIgnoreCase("class")){
isSearchCriteriaPresent = true;
break;
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
} catch (NoSuchMethodException e) {
e.printStackTrace();
if(!isSearchCriteriaPresent){
user.setFirstname("*");
OperationBinding opBinding = (OperationBinding)bindings.getOperationBinding("searchUsers");
opBinding.getParamsMap().put("user", user);
opBinding.execute();
AdfFacesContext adfFacesCtx = AdfFacesContext.getCurrentInstance();
Map<String, Object> scopePageFlowScopeVar= adfFacesCtx.getPageFlowScope();
scopePageFlowScopeVar.put("userSearchCriteria", user);
ADFContext adfCtx = ADFContext.getCurrent();
Map sessionScope = adfCtx.getSessionScope();
sessionScope.put("userSearchCriteria", user);
setUserSearchCriteria(user);
if(selectedUserID != null){
selectedUserID.setValue(null);
RichTable table = getUserResultsTable();
DCIteratorBinding searchUsersIterator = (DCIteratorBinding)bindings.get("searchUsersIterator");
Row[] rows = searchUsersIterator.getAllRowsInRange();
if(rows.length > 0){
RowKeySetImpl rks = new RowKeySetImpl();
ArrayList keyList = new ArrayList();
keyList.add(rows[0].getKey());
rks.add(keyList);
table.setSelectedRowKeys(rks);
table.setDisplayRowKey(keyList);
refreshState(table);
if(!isSearchCriteriaPresent){
user.setFirstname(null);
else{
deleteUserButton.setDisabled(true);
resetPasswordButton.setDisabled(true);
enableUserButton.setDisabled(true);
disableUserButton.setDisabled(true);
Thanks in advance for your help

Hi,
Can you try this?
1. set partialSubmit=true for the "search" button
2. set "search" button id as partialTrigger in your result table

Listening in main application for event coming from custom component

I have a custom component that im using for a login. i watch videos and tutorials on how to pass variables between custom components and application. the problem im having is that must tutorials or explanation have you put the event on the custom component and then it refers to some function within the main app.
Is there a way to just listen on the main app when that event kicks off? ive been trying for hours and i know there has to be something im missing it cant be that hard. any help i would really appreciate.
Thanks
Miguel

Sounds like you're asking about addEventListener():
     <fx:Script>
          <![CDATA[
               import mx.events.FlexEvent;
               protected function windowedapplication1_creationCompleteHandler(event:FlexEvent):void
                    comp.addEventListener("test", testHandler);
               private function testHandler(e:Event):void {
                    trace(e);
          ]]>
     </fx:Script>
     <local:TestComponent id="comp"/>
Add an event listener on your custom component (first string is the 'type' of the event).

Any Idea?

Hi,
there is a bug filed for this that has been fixed for the first (upcoming) Patch Set of 12c. Until then the solution seems to be to get the current row before exporting the table and then to set it back afterwards. So what you can try is to create a hidden button for the export of the table. Say you name the button "expBut". Then have another button with a action reference to a managed bean. This button now will invoke the following code
1. read the current row from the table iterator (bindings --> (DCIteratorBinding) bindings.get("iteratorName") --> (Row) dcIterator.getCurrentRow()
2. invoke the hidden button: ActionEvent ae = new ActionEvent(expBut); ae.queue();
3. Set current row back to where it was: dcIterator.setCurrentRowWithKey(row.getKey().toStringFormat(true));
At least this seems to be the internal bug fix.
Alternatively, disable PPR on the binding layer (ChangeEventPolicy=None on the iterator) and set the same on the PartialTrigger property of the component.
