Android Cache Event Listener

Hello guys,
I'm working in a project with HTML5 and Cache Manifest for Android or IOS device. The files was cached nicely for both devices, but, when I add event listener to the cache application on android device, it doesn't callback and the cache status stay 0.
My code example is: http://gist.github.com/felipehaack/c858e416e7187763739d
I really appreciate some help

I've sent this to our test team and they're taking a peek. I know we tested it in the past and it worked.

How to write a multi threaded Cache Event Listener

I have a distributed data cache called tokenCache for my application. I have also added a mapListener to this cache to listen to a particular kind of events.
tokenCache.addMapListener((MapListener) new TokenCacheListenerBean(), new MapEventFilter(tokenFilter), false);
So bascially everytime a token (The domain object of this cache) is updated the entryUpdated() method in my EJB TokenCacheListenerBean is invoked.
The issue I have though is that, from what I observe on running my code is that the Cache Listener is single threaded. So if two Token Objects on my tokenCache are updated,
lets say Token Object A and Token Object B one after the other, the entryUpdated() method in my EJB is invoked for Token Object A and once the invocation is complete
then the entryUpdated() method is invoked again for Token Object B(). At a given point of time there is only one instance of TokenCacheListenerBean EJB. Is there a way to
make this happen in multi-threaded manner ?
Is there a configuration setting somewhere which allows multiple CacheListeners to be instantiated at a given point of time ?

asdlCache.remove(asdlID);
jcaBean.provision(provisionAsdl, newToken.getTokenID());
logger.info(ConnectionManager.printTokenCache());
logger.info(printASDLCache());
}

Here is what I am asking!
I have added 2 listeners (Listener A and Listener B) which each listen on for changes made to 2 different token Cache Objects (Token A and Token B).
for (i = 0; i < 2 ; i++) {
Token tokenAdded = new Token(UUID.randomUUID().toString(),TOKEN_AVAILABLE, networkID);
tokenCache.put(tokenAdded.getTokenID(), tokenAdded);
     tokenCache.addMapListener((MapListener) new TokenCacheListener(), tokenAdded.getTokenID(), false);
Now assume that updates are made to Token A and Token B simuntaneosly.
Why do i observe in my diagnostic messages that only one Listener is invoked at a given point of time.
Which means I see Listener A getting invoked and then once invocation of Listener A is complete I see Listener B bieng invoked.
Ideally I would want both listeners to be invoked simultaneously rather than in a one off fashion.
Here is the code for my token cache Listener

Mixed/Double cache event listener events

Hi all,
Doing some very basic testing here now as we see what we can only assume to be strange behaviour.
Let's start with something simple:
package com.test;
import com.tangosol.net.CacheFactory;
import com.tangosol.net.NamedCache;
import com.tangosol.util.MapEvent;
import com.tangosol.util.MapListener;
public class RunKeyListener1 {
     public static void main(String... args) {
          NamedCache myCache = CacheFactory.getCache("my-cache");
          myCache.addMapListener(new MapListener() {
               @Override
               public void entryUpdated(MapEvent event) {
                    System.out.println("Key Update: Old: " + event.getOldValue() + ", New: " + event.getNewValue());
               @Override
               public void entryInserted(MapEvent event) {
                    System.out.println("Key Insert: Old: " + event.getOldValue() + ", New: " + event.getNewValue());
               @Override
               public void entryDeleted(MapEvent event) {
                    System.out.println("Key Delete: Old: " + event.getOldValue() + ", New: " + event.getNewValue());
          }, "Key1", false);
          myCache.put("Key1", 1L);
          myCache.put("Key1", 2L);
          myCache.remove("Key1");
Running this with default settings we get as expected this output:
Key Insert: Old: null, New: 1
Key Update: Old: 1, New: 2
Key Delete: Old: 2, New: null
All good so far, so let's add another listener on the same node, but now let's do a simple event transformer (which doesn't do anything actually):
Event transformer code:
package com.test;
import com.tangosol.util.MapEvent;
import com.tangosol.util.MapEventTransformer;
public class VoidTransformer implements MapEventTransformer {
     @Override
     public MapEvent transform(MapEvent event) {
          Object oldValue = event.getOldValue();
          Object newValue = event.getNewValue();
          MapEvent newEvent = new MapEvent(event.getMap(), event.getId(),
                    event.getKey(), oldValue, newValue);
          return newEvent;
Updated test code:
package com.test;
import com.tangosol.net.CacheFactory;
import com.tangosol.net.NamedCache;
import com.tangosol.util.MapEvent;
import com.tangosol.util.MapListener;
import com.tangosol.util.extractor.IdentityExtractor;
import com.tangosol.util.filter.LessFilter;
import com.tangosol.util.filter.MapEventFilter;
import com.tangosol.util.filter.MapEventTransformerFilter;
public class RunKeyListener2 {
     public static void main(String... args) {
          NamedCache myCache = CacheFactory.getCache("my-cache");
          myCache.addMapListener(new MapListener() {
               @Override
               public void entryUpdated(MapEvent event) {
                    System.out.println("Key Update: Old: " + event.getOldValue() + ", New: " + event.getNewValue());
               @Override
               public void entryInserted(MapEvent event) {
                    System.out.println("Key Insert: Old: " + event.getOldValue() + ", New: " + event.getNewValue());
               @Override
               public void entryDeleted(MapEvent event) {
                    System.out.println("Key Delete: Old: " + event.getOldValue() + ", New: " + event.getNewValue());
          }, "Key1", false);
          MapEventFilter mapEventFilter = new MapEventFilter(MapEventFilter.E_ALL, new LessFilter(IdentityExtractor.INSTANCE, 50L));
          MapEventTransformerFilter transformerFilter = new MapEventTransformerFilter(mapEventFilter, new VoidTransformer());
          myCache.addMapListener(new MapListener() {
               @Override
               public void entryUpdated(MapEvent event) {
                    System.out.println("Filter Update: Old: " + event.getOldValue() + ", New: " + event.getNewValue());
               @Override
               public void entryInserted(MapEvent event) {
                    System.out.println("Filter Insert: Old: " + event.getOldValue() + ", New: " + event.getNewValue());
               @Override
               public void entryDeleted(MapEvent event) {
                    System.out.println("Filter Delete: Old: " + event.getOldValue() + ", New: " + event.getNewValue());
          }, transformerFilter, false);
          myCache.put("Key1", 1L);
          myCache.put("Key1", 2L);
          myCache.remove("Key1");
I would expect the output from this to be:
Key Insert: Old: null, New: 1
Filter Insert: Old: null, New: 1
Key Update: Old: 1, New: 2
Filter Update: Old: 1, New: 2
Key Delete: Old: 2, New: null
Filter Delete: Old: 2, New: null
Instead I get this:
Filter Insert: Old: null, New: 1
Key Insert: Old: null, New: 1
Filter Insert: Old: null, New: 1
Key Insert: Old: null, New: 1
Filter Update: Old: 1, New: 2
Key Update: Old: 1, New: 2
Filter Update: Old: 1, New: 2
Key Update: Old: 1, New: 2
Filter Delete: Old: 2, New: null
Key Delete: Old: 2, New: null
Filter Delete: Old: 2, New: null
Key Delete: Old: 2, New: null
Similarly, changing the filtered listener to a lite listener this is the output:
Key Insert: Old: null, New: null
Filter Insert: Old: null, New: null
Key Insert: Old: null, New: 1
Filter Insert: Old: null, New: 1
Key Update: Old: null, New: null
Filter Update: Old: null, New: null
Key Update: Old: 1, New: 2
Filter Update: Old: 1, New: 2
Key Delete: Old: null, New: null
Filter Delete: Old: null, New: null
Key Delete: Old: 2, New: null
Filter Delete: Old: 2, New: null
Seems like the events are doubling up. Any clues?

Event Listener dispatcher giving an ClassCast Exception in C++ 3.6.1

Hi,
I have attached a Event listener to underlying NamedCache and when I update the cache entry I didn't get any alerts. But When I checked the
coherence log I found following Exception available. But I'm not doing any sort of Casting as mentioned below.

When I wrote a sample application It works without any problem. Only difference of above exception coming program is this c++ library is loaded true JNI and relevant event listener is added during a JNI method call. Please explain me why this exception is coming. I have attached the relevant code as well.

Hi,
Even when I try to to test the MemberListener while closing the Coherene Java Cache Cluster I can see following Exception. Something similar to EventListener.

Error ocurring when Event Listener methode in "for statement" is called

Hy guys,
I would be gratefull if somebody could answer me how can I
call a method from flex in "for statement", that is actually in my
remote service implemented. I call the method loadAssetsResult()
(event listener method in my action script) and get a collection of
objects back. In the same method I want to iterate throught this
collection and call another method from remote service, that is
specified for this object. Problem is when I call this remote
method inside of this loop statement. I get the error when I write
my code like following one:
public function loadAssetsResult(event:ResultEvent):void {
for (i=0; i<event.result.length; i++) {
a = new Asset();
a.longName = event.result
.longName;
a.shortName = event.result.shortName;
a.isin = event.result
.isin;
a.nsin = event.result.nsin;
a.currentDayClose = event.result[0].currentQuote.dayClose;
//Schluskurs
assets.addItemAt(a, i);
RO.getIndicatorCollection(i);
DataBinding();
When I comment the row: RO.getIndicatorCollection() it works,
of course without these additional data that I get from that
method. I need to call this method inside loop statement (for each
object), but I don't know how, without getting this error?
please somebody help me with some ideas

Kris,
First of all you should increase the value of logging-config/character-limit element in tangosol-coherence.xml to see the message entirely. The default setting is 4096 which is not enough to see your exception text.
When you do that I believe you will see that the actual exception is java.lang.ClassNotFoundException indicating that the node that has the listener installed doesn't know about the class that is being put into the cache and could be easily fixed as shown here: http://www.tangosol.com/faq-coherence.jsp#classnotfound
Please let me know if that doesn't help.

Adding an event listener to combo box

I am working on a mortgage calculator and I cannot figure out how to add an event listener to a combo box.
I want to get the mortgage term and interest rate to calucate the mortgage using the combo cox. Here is my program.
Modify the mortgage program to allow the user to input the amount of a mortgage
and then select from a menu of mortgage loans: 7 year at 5.35%, 15 year at 5.50%, and
30 year at 5.75%. Use an array for the different loans. Display the mortgage payment
amount. Then, list the loan balance and interest paid for each payment over the term
of the loan. Allow the user to loop back and enter a new amount and make a new
selection, with resulting new values. Allow user to exit if running as an application
(can't do that for an applet though).

The OP already did this to both JComboBoxes.
mochatay, here is a new actionPerformed method for you to use.
I've improved a few things here and there...
1) You can't just cast the ActionEvent's source into a JComboBox!
What if it was a JButton that fired the event? Then you would get ClassCastExceptions (I'm sure you did)
So check for all options, what the source of the ActionEvent actually was...
2) You can't assume the user will always type in valid data.
So enclose the Integer and Double parse methods in try-catch brakcets.
Then you can do something when you know that the user has entered invalid input
(like tell him/her what a clumsy idiot they are !)
3) As soon as user presses an item in any JComboBox, just re-calculate.
I did this here by programmatically clicking the 'Calculate' button.
Alternatively, you could have a 'calculate' method, which does everything inside the
if(command==calculateButton) if-block.
This will be called when:
a)calculateButton is pressed
b)when either of the JComboBoxes are pressed.
public void actionPerformed (ActionEvent event)
        Object command = event.getSource ();
        if (command == calculateButton) //calculates mortgage payment
            int year = 0;
            double rate = 0;
            double mortgage = 0;
            double interest = 0;
            /* If user has input invalid data, tell him so
            and return (Exit from this method back to where we were before */
            try
                year = Integer.parseInt (mortgageTerm.getSelectedItem ().toString ());
                rate = new Double (interestRate.getSelectedItem ().toString ()).doubleValue ();
                mortgage = new Double (mortgageAmount.getText ()).doubleValue ();
                interest = rate / 100.0 / 12.0;
            catch (NumberFormatException nfe)
                /* Display a message Dialogue box with a message */
                JOptionPane.showMessageDialog (this, "Error! Invalid input!");
                return;
            double monthly = mortgage * (interest / (1 - Math.pow (interest + 1, -12.0 * year)));
            NumberFormat myCurrencyFormatter;
            myCurrencyFormatter = NumberFormat.getCurrencyInstance (Locale.US);
            monthlyPayment.setText (myCurrencyFormatter.format (monthly));
        else if (command == clearButton) //clears all text fields
            /* Better than setting it to null (I think) */
            mortgageAmount.setText ("");
            //mortgageTerm.setText(null);
            //interestRate.setText(null);
            monthlyPayment.setText ("");
        else if (command == exitButton) //sets exit button
            System.exit (0);
        else if (command == mortgageTerm)
            /* Programmatically 'clicks' the button,
            As is user had clicked it */
            calculateButton.doClick ();
        else if (command == interestRate)
            calculateButton.doClick ();
        //JComboBox mortgageTerm = (JComboBox) event.getSource ();
        //String termYear = (String) mortgageTerm.getSelectedItem ();
    }Hope this solves your problems.
I also hope you'll be able to learn from what I've indicated, so you can use similar things yourself
in future!

Can't remove event listener from Image

I'm clearly missing something and would appreciate some help. I'm trying to run an event handler when an Image completes loading, then remove the handler so that it won't run again should the image be reloaded later.
The problem that I'm having is that the event handler simply wont' go away, despite calling removeEventListener on the Image object.
The following example demonstrates the problem (the example doesn't actually do anything useful...it's just the shortest example to demonstrate the problem). (To run the app, you'll have to provide any ol' JPEG file named "myImage.jpg" in the "src" directory of your project).
What I expect to happen is :
     1) on startup, the image loads and loadComplete() runs.
     2) loadComplete removes the event Listener so that subsequent re-loads won't re-fire the handler. I only want the handler to run once.
     3) "loadComplete" shoudl be displayed in the Debug console.
     4) A button click should display only "Changing Image" in the Debug console
What I get instead is that the loadComplete handler isn't removed, and every time I click the button, loadComplete runs when the image is re-loaded   (i.e., every button click results in both "Change Image" AND "loadComplete" being displayed in the Debug console).

Hi,
You can remove only event listeners that you added with the addEventListener() method in an ActionScript block. You cannot remove an event listener that was defined in the MXML tag, even if it was registered using a call to the addEventListener()method that was made inside a tag attribute.
Check this page for reference.
http://livedocs.adobe.com/flex/3/html/help.html?content=events_05.html
You can modify the code a bit a get it working
<mx:Image width="655" height="181" id="myImage" scaleContent="true"
          x="100" y="100"
          creationComplete="myImage_creationCompleteHandler(event)"/>
private function myImage_creationCompleteHandler(event:FlexEvent):void
     myImage.addEventListener("complete",myImage_completeHandler);
     myImage.load("myImage.jpg");
private function myImage_completeHandler(event:Event):void
     myImage.removeEventListener("complete",myImage_completeHandler);

How do I assign a mouseclick event Listener to a simplebutton already nested in a movie clip when it's dropped on stage?

I'm trying to assign a mouseclick event listener to a simplebutton nested within a movie clip's later frames, starting at frame 2 and up. This card, however, is not added to my game until later, and when the player clicks on it/turns it over.
There are four files involved in this program:
#1 The main actionscript file, which corresponds to
#2 my dreamQuester .fla file.
#3 my artifactCard file movieClip's corresponding .as file,
#4 my combo1.as file corresponding to a an instance of a simpleButton named combo1 that is already
nested --and this instance is already named-- inside/as a child of said artifactCard movieclip.
What I've done so far isn't working:
In my main dreamQuester.as file, when a player clicks on an artifactCard, its MOUSE_DOWN event
listener takes them to this function (clickArtCard), where the trouble is at:
// player clicked on the artC card--which is a child of posArt1 on stage--to turn card over:
        function clickArtCard(a_event:MouseEvent) {
            var thisArtCard:artifactCard = (a_event.target as artifactCard);
            thisArtCard.gotoAndStop(unclickedArt1); // go to frame number of artifact
                                // card where combo1 button is.
            thisArtCard.removeEventListener(MouseEvent.CLICK,clickArtCard);
            thisArtCard.buttonMode = false;
            trace("combo1.combo is:" + combo1.combo);
            trace("posArt1.artC.combo1 is:" + posArt1.artC.combo1);
            posArt1.artC.combo1.addEventListener(MouseEvent.MOUSE_DOWN, comboClickedWHO);
when the artC card--the static public instance of artifactCard--is clicked, it only gets to the
trace("posArt1.artC.combo1 is:" + posArt1.artC.combo1); which returns this error message:
TypeError: Error #1010: A term is undefined and has no properties.
    at MethodInfo-61()
So do how would I declare a static public variable of this simpleButton at the start of my main .as
file to make it defined to get a mouseDown actionListener into my pre-existing-and-named-instance
combo1 simpleButton?
perhaps there is a way, while the debug movie program is running, to click on the simpleButton and see exactly
what it's parent heirarchy is, to see the name of all parents above the simpleButton incase they are
different then what I think?
(just in case, I was hoping to squeeze a zip file containing these files to be less than 9MB incase someone was willing to look at my files to see what I've done so far, but 9 megs is just too big! even though all graphics I've imported where turned into vector graphics with trace bitmap. I wish there was a way to check the file size of each symbol in Flash CS4, here...)
Thank you so much for any help!

Just use a
stage.addEventListener(KeyboardEvent.KEY_DOWN, keyPressed);
function keyPressed(event:KeyboardEvent):void {
     //trace(event.keyCode);
     if(event.keyCode == ???){
          // play the sound
Where I show the "???" you would replace with the keyCode for the key you want pressed for that sound. To determine the keyCode you can use the trace line that I have commented out.
Note that when testing in Flash you often need to disable the keyboard shortcuts in the Flash Player in order to be able to use alot of the keys. You will find this option in the Control menu options in the player.

How can I check if a function is or is not called from the event listener? in Flash CS4 (AS3)

Hi,
I came across a little problem.
I put an event listener inside a for loop and the for loop inside a function.
I want the for loop to end as soon as the event listener inside the for loop calls its function.
Here is the general code for a better picture.
Code:
this.addEventListener(Event.ENTER_FRAME, function#1);

Thank you for any help!

that for-loop (if it executes), defines listeners for interactive objects. that will complete long before any object is clicked.
Well yes but it does it again and again (frames per second times seconds = number of times it goes through the code if i'm not mistaken), because it is inside a function, and through testing i found out that it works like this:
Example:
there are 5 my_mc's in my project: (my_mc_0, my_mc_1, my_mc_2, my_mc_3, my_mc_4)
if i click my_mc_0 function#2 is called and executed. BUT only after the loop finishes (i know this from tons of testing)...which is unnecessary since you cannot click two places at once. This might not be a problem in this example because i am only using 5 my_mc's buy if i use 500000000 my_mc's it would make a lot of difference.
is there a way to stop the loop if the function is called?
...maybe there is a better way to write it, the only alternative i know that works is if i manually write every single listener and this also is logical in this example but as i said next to impossible if the numbers get bigger.
-Note
I didn't specify this earlier but function#2 makes the if statement false so it wont jump back into it.
Thank you for the help I really appreciate it!

Help with event listener

I'm having some trouble trying to figure out how this event listener will work.
The main application is building an arrayCollection of a calendarDay custom components which is displayed by a DataGroup.
Within each calendarDay custom component i may create an arrayList of a DriverDetailComponent custom components displayed within the calendarDay by a DataGroup.
If a user double clicks on the DriverDetailComponent that is two layers in I would like to change states of the main application. I'm having trouble figuring out what item in the main application to set the listener on. Please help.
I can't figure out how to post the below as scrollable code snips so this is very long.
Main application code:

I'm trying to add a listener to [this JOptionPane pane dialog box|http://beidlers.net/photos/d/516-1/search_screenshot.JPG|my dialog box], so that when it pops up, the cursor is in the text box, but then if the user clicks a button other than the default, the cursor reverts back into the text box.
The code I have is this:
// BUILD DIALOG BOX
JLabel option_label = new JLabel("Select a search option:");
// Create the button objects
JRadioButton b1 = new JRadioButton("Search PARTS by name");
JRadioButton b2 = new JRadioButton("Search ASSEMBLIES by name");
JRadioButton b3 = new JRadioButton("Search DRAWINGS by name");
JRadioButton b4 = new JRadioButton("Search all by DESCRIPTION");
b1.setSelected(true);
// Tie them together in a group
ButtonGroup group = new ButtonGroup();
group.add(b1);
group.add(b2);
group.add(b3);
group.add(b4);
// Add them to a panel stacking vertically
JPanel panel = new JPanel();
panel.setLayout(new BoxLayout(panel,BoxLayout.Y_AXIS));
panel.add(b1);
panel.add(b2);
panel.add(b3);
panel.add(b4);
JLabel name_label = new JLabel("Enter a search term (add *'s as required)");
JTextField name = new JTextField(30);
name.addComponentListener(new ComponentListener() {
public void componentHidden(ComponentEvent ce) { }
public void componentMoved(ComponentEvent ce) { }
public void componentResized(ComponentEvent ce) {
ce.getComponent().requestFocus();
public void componentShown(ComponentEvent ce) { }
Object[] array = { option_label, panel, name_label, name };
// GET INPUT FROM USER
int res = JOptionPane.showConfirmDialog(null, array, "Select", JOptionPane.OK_CANCEL_OPTION);
String searchTerm = name.getText();This sucessfully has the focus in the text box when opened; is there a way to get the focus to go back into the text box after the user clicks a radio button?
Thanks!

you will need to add ItemListener to the JRadioButtons

Remove event listener from loaded external swf

I have a main movie timeline that loads an external swf. When I unload the swf from the main timeline I get an error from this: my_FLVPlybk.addEventListener(VideoEvent.COMPLETE, vidEnd);
is there any way to remove the event listener from the loaded swf from the main timeline?
THANKS!

if you're publishing for fp 10+, use unloadAndStop() applied to your swf's loader. that has a fair chance of solving the problem.
if that fails, you should explicitly stop my_FLVPlybk.

Keyboard Event Listener doesn't work in Browser

Is there a reason why a keyboard event listener would not work if the flash is embedded in an HTML? The rest of my game is running fine in the background, but I can't launch the movieClip "nextCar." My code is below, if that makes any difference...
function goNow (event:KeyboardEvent): void {
    thisOtherKey = event.keyCode;
    if (thisOtherKey == 32) {
        nextCar.gotoAndPlay(2);
        parkingQue.play();
        tries++;
stage.addEventListener(KeyboardEvent.KEY_DOWN, goNow);

This may be a silly question, but have you tryed clicking on your swf after it opens up in the browser, and then trying the keyboard controls?
I don't know of any issues that cause event listeners to workwhen debugging, but not in a browser. So, I'm thinking maybe your just not focused on the swf.

How to send the Event Listener arguments in AS3?

In MXML
<mx:Button click="clickHandler();"
mouseDown="downHandler(event);" mouseOver="overHandler(btn);"
mouseMove="moveHandler('RAJAN');"/>
but AS3
var btn:Button = new Button();
btn.addEventListener(MouseEvent.CLICK, clickHandler, flase,
0, true);
only this kind of AS3 event only added, any other possibility
to pass the arguments to handler function.
please help.

From that link:
If you define an event listener inline (inside the MXML tag),
you can add any number of parameters as long as the listener
function's signature agrees with that number of parameters.
If you add a listener with the addEventListener() method (in
ActionScript), you cannot pass any additional parameters to the
listener function, and that listener function can declare only a
single argument, the Event object (or one of its subclasses).
To pass additional parameters to listener functions defined
in AS, you must define the parameters in the listener function and
then call some other method passing it the additional parameters in
the call from the listener.
You can also define your own custom events, and then you are
free to define what args your event listeners take, and access the
data from the event object.

Is there any event listener for changing the selection of layer?

Hi all,
I am looking into an event listener which fires on changing the selection of layer. I found 'Select' event listener which fires on selecting the different object.
Actually the problem with Select event listener is that when we select an object and move it and deselect it by clicking on the document, event fires on the selection of that object. But if we again select the same object and move it, no event is fired at that time.
Is there any workaround of this? So that the event is fired every time when we select the same object.
Please help me on this..
Regards,
VG.

Thanks for the reply..
Actually I want the same behaviour as in illustrator i.e
- Select a layer. (Notifier calls the listener)
- Move it.
- Click on the document.
- Again select the same layer. (Notifier calls the listener again)
- Move it.
But in photoshop,
- Select a layer. (Notifier calls the listener)
- Move it.
- Click on the document.
- Again select the same layer. (Notifier doesnot calls the listener again as the layer is already selected in panel as you explained.)
- Move it.
Is there any way to get the same behaviour of illustrator in photoshop?

How does custom event listener work.

Hi,
With reference to Custom Event Listener, I wanted to know the behaviour of Custom Listener whether they are sync or async.
For Example :
Suppose i have a method1() which has the listener1() get invoked at some operation at line #1 of method();
The task of listener1() takes 2 minutes aprox.
Then my question is does method1() waits until listener1() finishes its task(2 Minutes) ?
What is he default behavior of listner1()
Can we change the default behavior of custom listners ?
Thanks & Regards,
