Calling action listener for a BUTTON component in java bean page

Question

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.

Answer 1

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});
