How to call a method when navigating records?

Jdev 11.1.1.2.0
I have an app displaying records one at a time in a panelFormLayout.
I have a selectManyShuttle object linked to the form with a PartialTrigger.
The shuttle is being populated using the methods from the SRDemo app and are functioning correctly when adding/removing records including the correct parent id through the partialtrigger.
But, the shuttle is not refreshing as the parent record is changed. I have to manually refresh it.
How can I attach a method call #{backing_MessageTrainingCenters.refreshSelectedList} to fire when the parent record navigates or is there a way to do this automatically?
Same question with the commit button. I currently have a save button for the shuttle and a commit for the parent. I would like to call the method to save the shuttle records when the commit is pressed.

What I've done to sort of get this to work
In the backing bean (using the SRDemo stuff) I changed the refreshSelectedList to use an ActionEvent
public void refreshSelectedList(ActionEvent event) {
refreshSelectedList = true;
I right-clicked one of the the built in nav buttons and told it to create method binding for action then took that method and made it take a string for the operation.
public String navAction(String navigate) {
BindingContainer bindings = getBindings();
OperationBinding operationBinding = bindings.getOperationBinding(navigate);
Object result = operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
return null;
return null;
I made 4 buttons and set the ActionListener to #{backing_MessagePrograms.refreshSelectedList} on each one then did a create method binding for action.
Inside each of these methods I made a call to navAction(String navigate) above passing in the operation I want.
public String cb8_action() {
cb2_action("First");
return null;
This works ok for this single scenario but I have 2 multi select lists to refresh when navigating. So I'm still stuck with trying to tell the other component to refresh.
I cannot find the "magic" that happens when I click the button with the listener ActionListener set that makes it refresh.
How can I tell both multiselect components to refresh from one of my methods?
or
*How can I set a button to use 2 ActionListeners like #{backing_MessagePrograms.refreshSelectedList} & #{backing_MessageTCs.refreshSelectedList}?*

How to call a method when the browser is closing

Hello,
In my application I need to execute a specific treatment when the WD4A application is closing. So how can we have a handle method for this specific event.
I've seen some documentation about the "exit plugs" , and about the doonclose method of the window.. but I don't think it can be useable for me in this case.
Can you please help me
Thanks in Advance
Hamza

I wrote an insert into the method i set up a break point, the program never call this code and therefore, the new row is never inserted.
But i think, it's a misunderstand.
to summarize :
I have an application in WD4A
The application is running, and then I decide to close the browser (in my case internet explorer) and before the browser close I want to execute a piece of code.
If the method wddoonclose is to be used, is there any default handler or listener to trigger it automatically on the browser closing ?
If no, how to trigger a method base on this special event .
Thx
Hamza

How to call a method when initialing the page?

Help! I need to call a method to get some information from server to create a part of the page.
But I don't konw what to do, Is there a function similar to the Flex's createComplete in JavaFX.

You can also use the public override function run() function to ensure it is executed first.

How to call a method defined in AM when I select any value in LOV

Lets say there is a LOV. The scenario is as soon as I select any value in LOV, a method needs to be called which I have written in the AM. And the output of the method is displayed in a output text box.
I am not able to understand how to call a method when the user selects any value in LOV.
This is wht I did. I had created the binding for the method. Changed the autosubmit property of the LOV to True, and in the properties of the output box, in the partial submit trigger property, passed the ID of the LOV. But I didnt get any place where I need to call the method. I am also not able to drop an action listener on the LOV

Hi,
+"its showing an error(underlined in orange)."+
Any reason you don't share this error with us? Anyway, here is how it goes
1. LOV, set autosubmit="true" and configure a value change listener
2. Expose the AM method as a method binding in the PageDef file
3. In the value change listener:
BindingContext bctx = BindingContxt().getCurrent();
BindingContainer bindings = bctx.getCurrentBindingsEntry();
OperationBinding method = (OperationBinding) bindings.get("name of method binding in PageDef");
method.getParamsMap().put("argument name1", value1);
method.getParamsMap().put("argument name2", value2);
Object retVal = method.execute();
if(!method.getErrors().isEmpty()){
//handle errors
else{
//write retVal to the managed bean variable that is referenced by the outputText value property
//PPR output text component
ADFFacesContext.getCurrentInstance().addPartialTarget(outputTextRef);
}Note that you may have to set clientComponent = "true" on the output text component

How to call a method from a separate class using IBAction

I can't work out how to call a method form an external class with IBAction.
//This Works 1
-(void)addCard:(MyiCards *)card{
[card insertNewCardIntoDatabase];
//This works 2
-(IBAction) addNewCard:(id)sender{
//stuff -- I want to call [card insertNewCardIntoDatabase];
I have tried tons of stuff here, but nothing is working. When i build this I get no errors or warnings, but trying to call the method in anyway other that what is there, i get errors.

Can you explain more about what you are trying to do? IBAction is just a 'hint' to Interface Builder. It's just a void method return. And it's unclear what method is where from your code snippet below. is addNewCard: in another class? And if so, does it have a reference to the 'card' object you are sending the 'insertNewCardIntoDatabase' message? Some more details would help.
Cheers,
George

How to call a method in jsf after stop typing in test box?

Hi all,
In my jsf page i have a text box in which user type some text field like "abc". i want after stop the typing i want a method to be called automatically and a datatable will be populated sith some result. my problem is is how to call the method automatically so that the user does not have to click any button after typing in the text box? plz help..
Edited by: sailajoy on Dec 23, 2008 3:36 PM

If it is after certain characters that the user types you can ascertain that the entry is done you can use onkeyup and within the javascript count the characters an when the necessary characters are set do the action you need to do.
There should be some way by which you can suggest that the user has stopped typing i.e. either the max length has reached or the user has hit tab or went to another field. Going on other field too you can bring the focus back to your original field from where the user had hit tab. If you are thinking of something liek google suggest then AJAX is the best way to implement it.

Beginner's query: How to call a method on close of a frame?

Hi. I wrote a frame that inherits from JFrame. There I called *"setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE)"* (more or less). I now wish that the frame would call a method when it closes.
How can I define that? I assume some action listeners should be added, but I would appreciate a thorough reply.
Thank you!!

Could someone please explain to me the main difference between adapters and listeners? WindowListener is an interface, if you use it then you have to implement all its methos whether you use then or not while WindowAdapter is a class which implements WindowListener and provides empty implementations of all the methods in the listener, so basically by using windowAdapter you are avoiding
the implementation of methods which you don't required.

How to call java method having array as argument from c++ ?

Hello sir,
how to call java method having array as arguments from c++;
here is java code which is called from c++
class PQR {
     public void xyz(int[] ia) {
     System.out.println("hi");
          for (int i = 0; i < ia.length; i++)
               System.out.println(ia);
suppose all jvm invocation is done...

For someone well versed in java, C++ and JNI although tedious that should be obvious.
For someone not well versed in all three it is going to be very difficult.
Even for someone that does have knowledge in all of those areas coming up with a C++ interface that reflects that functionality in a dynamic way such that anyone is will to use it is going to be quite an adventure.
At any rate to start building it you do exactly the same thing that you would in java.
1. Extract everything in the jar via the zip package
2. For each found instance extract all of the methods, return types, parameters, etc and build a description tree for each class.
Doing all of that in C++ is going to take a LOT of code. If someone wanted an estimate from me it would take me 6 months to do it. And before I would even attempt it I would get them to explain to me in detail exactly how they thought they were going to use it when I was done because I can't see any reasonable way to do that.
I left out the description tree itself. I suppose you could duplicate the entire reflection api in C++.
Now perhaps if it was much, much more constrained, like to only those classes that implement a single interface then that would be more reasonable.

How to call java method on page load?

How to call java method on page load?
Thanks

Hey Dan,
Well, if you want to execute a java method when page is load, you need to put the clientlistener in af:document. Let me to show you an example (I can't find my post :P),
JSPX page:
<f:view>
<af:document>
<f:verbatim>
<script>
    function loadPage(event) {
        alert('Hello World!');
</script>
</f:verbatim>
<af:clientListener method="loadPage" type="load"/>
</af:document>
</f:view>If you try this code you can see that when the page has been load, you recieve the alert "Hello World!".
Furthermore, this is the javascript AJAX function that let you to call a servlet:
function ajaxFunction () {
    var httpRequest;
    if (window.XMLHttpRequest) {
        httpRequest = new XMLHttpRequest();
    } else if (window.ActiveXObject) {
        httpRequest = new ActiveXObject("Microsoft.XMLHTTP");
        httpRequest.overrideMimeType('text/xml');
    httpRequest.onreadystatechange = function() { alertContents(httpRequest); };
    httpRequest.open('GET', '/appname/servletname', false);
    httpRequest.send('');
function alertContents(httpRequest) {
    if (httpRequest.readyState == 4) {
        if (!httpRequest.status == 200) {
            alert('Request error. Http code: ' + httpRequest.status);
}Where 'appname' is your application name and 'servletname' is the name of the servlet that you want to call. Obviously, you can call any URL ;)

How to call a method in private section of a class in the public section

Hi Everybody,
i have written a method(meth1) in the private section of a class(C1).
it is as follows
class C1 definition.
private section.
methods: meth1 importing im_dt1 like tp1
                                         im_dt2 like tp2
                                         im_dt3 like tp3
                                         im_dt4 like tp4
                           returning value(re_dt1) like tp5.
endclass.
i have the final data that has to be displayed in internal table re_dt1.
now my question is how to call this method present in private section into public section and display the data present in re_dt1.
Thanks,
learning.abap.

Hi,
what you need is one public method being called at start-of-selection. Within this the private methods have to be called.
The question is, why has the method for reading the database tables to be private? If you have only one private method reading all database tables the public method being called at start-of-selection will only consist of a call-method statement.
This seems to be one call to much.
The logic for reading the different database tables is hidden inside the class anyway.
Is there any further logic reading the different database tables?
Have always all table to be read? If not another approach would be one private method for each database table being called by a public method deciding which table has to be read:
public section.
methods get_data returning value(re_Dt1).
private section.
methods:
get_table_a returning value(im_dt1),
get_table_b returning value(im_dt2),
get_table_c returning value(im_dt3),
get_table_d returning value(im_dt4),
combine_data importing im_dt1
                                im_dt2
                                im_dt3
                                im_dt4
                        returning value(re_dt1).
*- implementation of public method:
method get_data.
data: lt_dt1 ...
           lt_dt2,
           lt_dt3,
           lt_dt4.
* here decide which tables have to be read:
lt_dt1 = get_table_a( ).
lt_dt2 = get_table_b( ).
lt_dt3 = get_table_c( ).
lt_dt4 = get_table_d( ).
re_dt1 = combine_data( i_dt1 = lt_dt1
                                       i_dt2 = lt_dt2
                                       i_dt3 = lt_dt3
                                       i_dt4 = lt_dt4 ).

How to call a method in the servlet from an applet

I want to get the data for the applet from the servlet.
How to call a method that exits in the servlet from the applet? I want to use http protocol to do this.
Any suggestions? Please help.
thanks

Now that Web Services is around, I'd look at possibly implement a Web Service call in your applet, which can then be given back any object(s) on return. Set up your server side to handle Web Service calls. In this way, you can break the applet out into an application should you want to (with very little work) and it will still function the same
