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:

Transaction Posting Confirmation Message and Action Listener behaviour

Hi, I have a scenario that a user is Posting a Transaction and when he press the “Post” Button a, confirmation dialog box should popup asking “Do you really want to Post the record ?”. If the user press “Yes” the record is further process and If the user press “No” then the transaction should not proceed.
I have implemented the main screen(PostTransaction.java) and the popup confirmation window(ConfirmationWindow.java)
Question 1 ) Why the code is not stoping in the Post Button Action listener as in JOptionPane, then how do i know that the user has selected "Yes" or "No" ?
Question 2) Do I have to write the code for posting of a Transaction(postTransaction() method) in the “ConfirmationWindow”? or it should be in “PostTransaction”.

The MII Message listener is a queue. But when I understand you correctly, you do not want to process the messages immediately after arriving in the Listener.
Maybe the categorization of messages is an option for you (see [Sap Help: Processing Rule Editor - Category|http://help.sap.com/saphelp_mii121/helpdata/en/43/e80b59ad40719ae10000000a1553f6/frameset.htm]. You can enter a category for the control recipe messages. The messages will then be placed in the Listener queue. You can use the [Message Services|http://help.sap.com/saphelp_mii121/helpdata/en/43/e80b59ad40719ae10000000a1553f6/frameset.htm] actions to read the categorized messages and process them as you need.
In addition to Manoj, you may also use the [Queueing actions|http://help.sap.com/saphelp_mii121/helpdata/en/43/e80b59ad40719ae10000000a1553f6/frameset.htm] of MII, where you can queue xml contents.
Hope this helps.

SDK 4.5 Form Component and States

I have created a s:Form component that will be used throughout my application. But FormItems are displayed depending on specific states of the main application file. I left the s:states element and its s:State children in the main application and just moved the portion of the form that I wanted to become a component. But I am getting State " " was referenced without being declared in my component mxml file. When I move my s:states elements from my main application file over to my component mxml file, the form does not react correctly.
So how do I get my form to correctly react to changing states in the main application???
Tony
States elements that are residing in my main application file:
<s:states>
          <s:State name="home" />
          <s:State name="searchMedia" />
          <s:State name="smResults" />
          <s:State name="lgResults" />
          <s:State name="addMedia" />
     </s:states>
The above states are tied to "navigation" buttons that also live in the main application file.
Here is the form component that I tried to create, but did not work ("Almost" only works in horseshoes and handgrenades):

Did I do something fundamentally wrong???

Thanks, Andrei!
Same exact problem here and your suggestion works.
However, it breaks things visually in terms of UI.
Will most likely have to address the data provider to limit the data.
Have you filed a JIRA bug with Adobe?

Transparency in Tree component and actions in its sheets

Hello people
I'm doing a kind of catalog, and I'm using a component "tree" for listing.
But here's the problem: I need to use the background I have in the scene, and the component has a white background I need to remove. The workaround I've found is to give 0 _alpha property to the instance of the tree I have in the scene, but it also hides its icons, and I need those visible.
The other thing is that I need that when you run over a leaf, multimedia displays a small view of an image, and when you click-go to a specific frame where I have the large image with description.
If anyone knows how can help me I would be greatly appreciated.
I searched the online help that Adobe is now, and I found these properties of the tree but there is no way to work (at least I need):
themeColor
backgroundColor
backgroundDisabledColor
depthColors
borderStyle
color
disabledColor
embedFonts
Thanks in advance.
P.S: Sorry my bad english

Use xml. Resistance is futile.

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.

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");

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});

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?

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]

I was trying to add a new menuitem to the web console. I have a jsp page like pag1.jsp and has pageForm and pageAction java file. Inside struct.config file I find that form and action files are placed under"com.thortech.xl.webclient.actions.tcAddCommentForm" , but when I search for the tcAddCommentForm, I coundn't find the file. Can u tell me where should I add my form And Action files

Just what to you mean? The Info pane for the iPod in iTunes allows you to sync the iPod contacts and calendar with other calendars and contacts. There is no contacts or calendar in iTunes.

Action listener activation in many phases

I need action listener (methods) to be activated in many phases. I.e., when the user clicks a submit button, I want code to be executed (in my case) after the validation phase and after (during) the invoke application phase. In earlier version of the standard, I would just register 2 listeners, returning the appropriate getPhaseId() value. Since this method is removed from the current standard, things get more complicated.
QUESTION: Why in heavens name was this method removed from the standard? I suppose, because it is difficult to support with listener methods (in contrast to instances)? Bit of a rough solution, no? Or am I missing something?
I have a solution now, I think, that is based on getting the action event immediate, and requeuing the event again and again.
In the JSP, in the JSF form, I have a submit button as follows:
<h:commandButton id="buttonId" value="ButtonText"
                 actionListener="#{handler.buttonListener}"
                 immediate="true"/>The method Handler.buttonListener is:
public final void buttonListener(ActionEvent ae) {
    LOG.debug("Handler. buttonListener called ("
              + "ActionEvent.getPhaseId() = " + ae.getPhaseId()
              + "; ActionEvent.getComponent() = " + ae.getComponent()
              + ")");
    PhaseId phaseId = ae.getPhaseId();
    if (phaseId.equals(PhaseId.APPLY_REQUEST_VALUES)) {
      LOG.debug("-- processing during " + ae.getPhaseId());
      // meaningful stuff here
      // prepare for execution in next phase
      ae.queue();
        /* this sets phase id to the current phase, so it is extremely important that
         * we set the necessary phase id AFTER queuing the event */
      ae.setPhaseId(PhaseId.PROCESS_VALIDATIONS);
      LOG.debug("-- ActionEvent (getPhaseId() = " + ae.getPhaseId() + ") queued");
    else if (phaseId.equals(PhaseId.PROCESS_VALIDATIONS)) {
      LOG.debug("-- processing during " + ae.getPhaseId());
      // meaningful stuff here
      // prepare for execution in next phase
      ae.queue();
      /* this sets phase id to the current phase, so it is extremely important that
       * we set the necessary phase id AFTER queuing the event */
      ae.setPhaseId(PhaseId.INVOKE_APPLICATION);
      LOG.debug("-- ActionEvent (getPhaseId() = " + ae.getPhaseId() + ") queued");
    else if (phaseId.equals(PhaseId.INVOKE_APPLICATION)) {
      LOG.debug("-- processing during " + ae.getPhaseId());
      // meaningful stuff here
    LOG.debug("Handler. buttonListener done");
}The /* */ comment in the code is there because the queue methods (on the event as well as the component) set the phase id of the event to the current phase. If I set the phase id of the event before queuing it, that setting is undone, and I get an infinite loop! This is weird, and my solution is at least shaky: it doesn't feel stable across JSF implementations and future releases. I could not find a queue method that leaves the phase id alone.
QUESTION: am I missing something?

As you can see, I get 3 consecutive calls of my listener method, but they are all during the apply request values phase, and we jump from the apply request values phase immediately to the render response phase, skipping all the other phases, although my listener is actually called 3 times.
QUESTION: what the fuck? What is happening here, and more important, how can I fix it?

I am in touch with IBM about any patch they might have for this. I just thought I'd post details from what I researched.
Basically I found that if I had CommandButton and/or CommandLink components on my page and clicked them for a total greater than 15 times, the application just quit reacting to any of the clicks. After writing a PhaseListener I discovered that after 15 clicks the JSF lifecycle was going straight from the Restore View (1) to Render Response (6) phase instead of going through the ones in between.
I downloaded the JSF source code and tracked down the magic number 15. As mentioned earlier in this forum it has to do with the number of views per session. In the Sun JSF-RI com.sun.faces.application.StateManagerImpl class
the number of views is defaulted to 15. When the number of views hits the max the oldest view is deleted. Somehow I don't think they are deleting the oldest view or else why my app quits after 15 clicks I do not know. Anyway this is a known issue with the Sun JSF-RI and documented in their Release Notes.
Depending on the JSF implementation there may or may not be a workaround. I mean to say the the workaround is not part of the JSF spec but Sun's implementation has a feature where you can configure the com.sun.faces.NUMBER_OF_VIEWS_IN_SESSION value in the web.xml file under the <context-param> tag. If you set the value sufficiently high you lower the risk of the app quitting on you (like a user may be unlikely to make 100 or even 50 clicks on the same page). You might also want to set the state to be saved on the server by setting javax.faces.STATE_SAVING_METHOD to server in another <context-param> tag. Somehow setting this state to client caused errors (NullPointerException) in our app in one of the Faces classes itself.
Hope this helps someone out there.

Property on Backing Bean is Not set when Action Listener is Fired

Why is it that when my action listener is invoked, the property for my other component on the page has not been reflected in model yet?
Here is what I have:
My JSP has the following two components:
<h:inputText value="#{manageQuestionBean.newStory}"></h:inputText>
<h:commandButton value="add" actionListener="#{manageQuestionBean.onAddStory}"></h:commandButton> My Java code has the following:
public void onAddStory(ActionEvent event) {
       //This always prints out 'null'
       System.out.println("The value of 'newStory' is: " + newStory);
      //TO DO: this is where the logic would go for creating a new story object.
    } When I put logging statements inside my setter for the newStory property, I see that it is being set to the right value, but then it being reset to empty string. Why is that? During what phase do the action listeners get invoked?

Which JSF implementation/version are you using?

When I put logging statements inside my setter for the newStory property, I see that it is being set to the right value, but then it being reset to empty string. Why is that? When exactly happens when exactly?
During what phase do the action listeners get invoked?The invoke application phase, after the update model values phase.
You may find this article useful to learn about phases and how to add a 'phase debugger' yourselfl: [http://balusc.blogspot.com/2006/09/debug-jsf-lifecycle.html].

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

JComboBox action listener

I have registered an action listener on a JComboBox.. I change the selected value of this combobox from another component's actions also.. My question is how can i distinguish between an action event in which an item was selected using the combo box directly and an event in which the selected value in the combo box was set by different comopnent.. the actionEvent.getSource gives the combo box itself..
Is using a mouselistener the only way out??

You can't and its a bad design to attempt to do so.dont know about bad design but.. in my case its required. I have to make a file chooser type User interface for browsing an ftp site.. So the combo box needs to be updated when the user changes a directory by double clicking on the directory.. Could i do something else?? please suggest anything u can
>
Is using a mouselistener the only way out?? What about if the user uses the key board to select
the item from the combo box? Would you also need to
write your own KeyListener? Getting very ugly.good point.. didnt think about this....now i understand why they used action listener
>
As a workaround, you could add code to your "other"
compnent:
comboBox.removeActionListener(...);
comboBox.setSelectedItem(...);
comboBox.addActionListener(...);thanks, does this have a significant performance penalty.. I mean it does not look good does it??

Add action listener to table cell

The topic of my previous thread was:
How can I get characters, which user inputs into table cell?
I've added lisateners to table:
table.addKeyListener(new java.awt.event.KeyAdapter() {
            public void keyPressed(java.awt.event.KeyEvent evt){
                System.out.println("keyPressed");
            public void keyReleased(java.awt.event.KeyEvent evt){
                System.out.println("keyReleased");
            public void keyTyped(java.awt.event.KeyEvent evt) {
                System.out.println("keyTyped");
        });But it's not exactly what I need.
I need to do the same, but with table cell.
I want to see user input char by char and set color font for user input string.
How can I add action listener to tble cell?

This is my newly created JTextField which I will use as CellEditor for My JTable
JTextField textField = new JTextField(); //creating Component
        textField.addKeyListener(new java.awt.event.KeyAdapter(){ //adding KeyListener
            public void keyReleased(java.awt.event.KeyEvent evt){
                System.out.println("keyReleased" + ((JTextField)evt.getSource()).getText() + "column = " +table.getSelectedColumn());//test functionality
                if ( isColumnHasSameValue(table.getSelectedRow(),table.getSelectedColumn(), ((JTextField)evt.getSource()).getText() ) ){//test column for equal values
                    ((JTextField)evt.getSource()).setForeground(Color.RED); //if there is equal value set Color.RED for JTextField text
                else{ //else set Color.BLACK
                    ((JTextField)evt.getSource()).setForeground(Color.BLACK);
        table.getColumnModel().getColumn(1).setCellEditor(new DefaultCellEditor(textField)); //set custom CellEditor
private boolean isColumnHasSameValue(int row, int column, String testVal){
        testVal = testVal.trim().toLowerCase(); //put away UpperCase and empty spaces
        for(int i=0;i<model.getRowCount();i++){
           if(i == row){
               continue;//skip selected row where user inputs text
           if(model.getValueAt(i,column).toString().trim().toLowerCase().startsWith(testVal)){
                return true; //if test passed
        return false; //if there are no mathes
    }I have a question:
It seems to me, I did not use optimal solution for JTable values testing.
What can ty else?
Maybe, It is better to use
tableModel.getDataVector();And then use Pattern and Matcher ?
Am I right?

Export collection action listener error after second call

Any Idea?
Jhon Carrillo
Jdev 12c

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.

How to add action listener to internal frame?

I have frame Main where I am trying to add action listener.
Action listener should be listening button in frame Menu.
I think it should be:
Menu frame = new Menu();
frame.btn_start.addActionListener(this);but it seems to be doing absolutely nothing.
If I try to add in menu:
btn_start.addActionListener(new Main());it generates: java.lang.StackOverflowError
What should I do? Please help noob :)

To get better help sooner, post a [_Short, Self Contained, Compilable and Executable, Example Program (SSCCE)_|http://mindprod.com/jgloss/sscce.html] that clearly demonstrates your problem.
You're quite possible adding the ActionListener to the wrong component. And constructing a new instance of a class within the constructor is likely the cause of your StackOverflowError.
