Want to add Action Listener programmatically on a button created Progammatically.

Scenario is,

I want to add the listener of pressing a button I've manually created and added to the page over time.

public void editPanel (ActionEvent actionEvent)
{
System.out.println ("invoked");
}

This is my code to the action listener, she is hard-coded

Hey Zaid,

Try the following code.

1. create the inner class on your managed bean.

private class MyListener implements ActionListener {

{} public void processAction (ActionEvent actionEvent)

write your action listener code here...

System.out.println ("invoked");

}

}

2. then add actionListener class to your button.

Addpopup RichCommandImageLink = new RichCommandImageLink();

addpopup.addActionListener (new MyListener());

    I know it's very basic, but I get a message that says "current selection cannot have actions applied to it" when all I'm trying to add actions to the MovieClips and buttons, in addition to the images, I placed in the library. When I select the stage, however, I can apply actions to him. Anyone know what I'm missing? Thanks in advance.

    you shouldn't really apply actionscript to objects. There is nothing has nothing lost it doing so.

    Welcome on the support forums.

    I suggest that you crush navigationclick (and maybe keychar if you want to enter, return back... to do something).

    Please note that blocking operations, such as networking, must be executed on a separate thread. Do not put this code directly in the event handler.
