Action listener problem

I have created the following code and i want the "btnCreate" to open the frame eqstring, i have tried to implement the action listener and it compiles but when i run it the button does nothing
pnlCreate.add(btnCreate);
pnlSimpleExample.add(btnSimpleExample);
pnlHardExample.add(btnHardExample);
pnlTitle.add(new Label("MAIN MENU"));
pnlTitle.setFont(new Font("Arial", Font.BOLD, 36));
// Setup Main Frame
f.getContentPane().setLayout(new BorderLayout());
f.getContentPane().add(pnlCreate, BorderLayout.SOUTH);
f.getContentPane().add(pnlSimpleExample, BorderLayout.WEST);
f.getContentPane().add(pnlHardExample, BorderLayout.EAST);
f.getContentPane().add(pnlTitle, BorderLayout.NORTH);
this.setSize(300, 300);
btnCreate.addActionListener(
new ActionListener()
     public void actionPerformed(ActionEvent e)
     eqstring mainFrame = new eqstring();
     }

ADF TUTORIAL: PROBLEMS WITH "Export Collection Action Listener"

hello all,
environment:
windows xp
jedev 11.1.1.3.0
firefox 3.6.13
tutorial: Developing Ajax-Based User Interfaces with JSF: An Introduction to ADF Faces Rich Client Components
url: http://st-curriculum.oracle.com/obe/jdev/obe11jdev/ps1/adf_richclient/adfrichclient.htm
mainstep: "working with menus"
substep: number 5 "add collection action listener"
until the step "working with menus" works everthing fine. after i added the collection action listener and saved my work, the webapplication will not open. i see only a blank page and no error message.
when i delete the action listener works everything fine again.
how can i fix this issue? thx to everyone.
best regards
gunnar

I'm not sure if this is going to help anyone , but if you're stuck at that point of the tutorial , try to drop the "Export Collection Action Listener" onto the menuItem "Export To Excel" not under it;
So the xml under the source tab should look something like this :
<f:facet name="menus">
<af:menu text="My Options" id="m2" detachable="true">
<af:commandMenuItem text="Export To Excel" id="cmi1">
<af:exportCollectionActionListener type="excelHTML"
exportedId="t1"/>
</af:commandMenuItem>
<af:commandMenuItem text="Show Specials" id="cmi2">
<af:showPopupBehavior popupId=":::p1"/>
</af:commandMenuItem>
</af:menu>
Hope this helped somebody .

How can i disable an Action listener temporary?

hi folks,
I have a GUI with many Jcomboxes. Each one of them has an actionlistener.
The idea was: when one of those comboboxes is selected, then the selected value will appear on ALL the comboboxes (by using setSelectedIndex(int index)).
The problem is when i select a value on ONE of those comboboxes and set it on the others, the actionListener thinks that i selcted a value on the other comboboxes and starts setting the values again... I other words if i select one combobox i obtain an endless loop...
Is it possible to disable the action listener temporary when setting the selectd values on the other comboboxes?

Just use removeActionListener and then addActionListener

How to create a single action listener for a group of buttons

hi there.. i am new at java and i have a problem with my applet..
i am doing a virtual ticket programme..
i have a tab that says books seats.. in the tab, i am suppose to create 50 buttons.
i have done that already by using for (int i=1; i<=10;i++) 5 times for 50 buttons.
but i do not know how to set an actionlistener in the for loop for each of these buttons..
For example, if the user were to chose seat "no3" , a text area(already created) below will show something like "no3" and so on..
how do i bind these buttons into one single action listener so i do not have to create 50 actionlisteners and buttons individually..
appreciate the help..

You're killing me.
class MyFrame extends JFrame implements ActionListener
     JTextArea myTextArea = new JTextArea();
     JButton myButton = new JButton("My Button");
     JButton otherButton = new JButton("Other Button");
     MyFrame()
          super();
          myButton.addActionListener(this);
          otherButton.addActionListener(this);
          setLayout(new FlowLayout());
          add(myButton);
          add(otherButton);
          add(myTextArea);
     public void actionPerformed(ActionEvent e)
          Object source = e.getSource();
          if(source == myButton)
               myTextArea.append("My Button Pressed\n");
          else if(source == otherButton)
               myTextArea.append("Other Button Pressed\n");
}

Fragement page hangs on action listener in task flow

I have a scenario that I have a home page and it has a command button(button1) on clicking of which it replaces the main region through the help of task flow. Now this new page has another command button(button2) which navigates to the invoking page(after execution of some action listener).
The problem comes in when we try to click on the button2, then the page hangs by itself. This however works when we do a page refresh.
Any ideas of why this strange thing is happening?

... not with the information you provide. I assume that the case evaluation is based on invalid data.

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.

My Action Listener doesn't always listen!

hi.
I've set up an action listener on a pop up menu item..
usually when I click on it, I get into the appropriate actionPerformed(ActionEvent e) method.
Sometimes however, nothing happens.. It doesn't enter the action performed method at all.
what could be causing this strange behaviour?

I haven't come across this problem before - can you post your code (if it's not too long) ? or wait up for somebody else to reply!

Listening problem

Ok here goes.
I currently have a main Jframe which contains a splitpanel. On the left side the split panel there is a jtree which is generated using beans. A jtree listener loads on the right hand side diffarent jpanels which are on separate files(classes) depending on which node the user selected. The jpanels loaded contain textboxes, labels and a save button. The problem is, I need the main class(Frame) to know if the save button has been pressed so that I can refresh the tree. Do i need to use a listener on this external class???
any help would be greatly appreciated!!
Thanks in advance.

You should make the main frame an action listener.
public myFrame extends JFrame implements ActionListener Then add it to the save buttons' actionlisteners.
saveButton.addActionListener(this);In the frame's actionperformed event, update the tree.
public void actionPerformed(ActionEvent ae) {
if (ae.getSource() == saveButton) {
// do your updating
}Here is a link that should help:

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?

During what phase do the action listeners get invoked?The invoke application phase, after the update model values phase.

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.

I need a code example for an action listener for a jcheckbox using matisse

I am trying to make it so that when some body clicks a jcheckbox it will put a figure into a jtextfield. Because I am using matisse I need to know the code for the action listener and I need to know quickly as well so I don't have time to look it up with searches etc.
Can anbody provide me with some example code please.

I thought that as you are all more experienced than I am that you would know where to look and as you would have already been to all of the sites you would have been able to save me a lot of time looking for the best one. I didn't mean to insult you sorry, I knew that I would be looking for a long time and hoped that some one could help speed that up for me.
Any way I have obviously annoyed you in that thread earlier this week. I know that you are all pee'd at me and don't believe me and that is fine. I have learnt every thing that I need to learn and would like to thank you for your help although I think that your language in your last post was not very pleasant, but that is ok.
I don't want to continue posting any more. But thank you for your help.

Issue with setting an Action Listener for a Command Button

Hi all,
I'm trying to set an action listener for a CoreCommanButton in a backing bean. Here's my code:
     CoreCommandButton editBtn = new CoreCommandButton();
          MethodBinding mb = FacesContext.getCurrentInstance().getApplication().createMethodBinding("#{backBean.doButtonAct}",null);
          editBtn.setActionListener(mb);
//Action listener method
     public void doButtonAct(ActionEvent actionEvent)
I keep getting a javax.faces.el.MethodNotFoundException error. However when I remove the ActionEvent parameter in doButtonAct(), I get a wrong number of arguments error.
So i'm guessing there is something wrong with the parameters i accept in my action listener method. what can be causing this issue?
Cheers.

I figured this out.
Since doButtonAct() requires an ActionEvent object as a parameter, i needed to define the parameter type when I create the method binding.
Solution:
     Class argsString[] = new Class[] { ActionEvent.class };
          MethodBinding mb = FacesContext.getCurrentInstance().getApplication().createMethodBinding("#{backBean.doButtonAct}",argsString);

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});
