Can you please help how this can be done ? Thanks.

Thanks. What are the steps for adding a custom delete button ?
Are these ok ?
1 ) Add an adf button
2) Add the following in the actions listener : #{bindings.Delete.execute}
3) Right Click button --> create method binding for action
4) Compare date ?
Thanks.

How do I take pics off my photo albums when the delete button is muted?

How do I take pics off my photo albums when the delete button is muted?

Were these photo albums synced onto the iPad through iTunes? If so, the only way to remove them is to do another sync (from the same computer) without the ones you want gone.

Triggering methods when a user clicks on a tabb in a JTabbedPane

triggering methods when a user clicks on a tabb in a JTabbedPane.
How can it be done? what listener should i use?

Well, after READING the JTabbedPane API, it appears
there is an addChangeListener()[/i[ method, so my guess
would be a [i]ChangeListener ?
And the source for the ChangeEvent would be the JTabbedPane
so you could then easily call getSelectedIndex() to find
out which pane is selected.

Hi, thankyou for your response. Can I just confirm that you mean turning the computer on and off again, or re-booting the whole system. If it is the first I have already turned the system on and off, with no luck.

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 did the photos get onto the iPad ? Only photos taken with the iPad, copied onto it via the camera connection kit, or saved from emails/websites etc can be deleted directly in the iPad's Photos app - either via the trashcan icon in the top right corner if viewing the photo in full screen, or via the icon of the box with the arrow coming out of it (Edit button on iOS 6) in thumbnail view.
Photos that were synced from your computer can't be deleted directly in the Photos app - you either need to move/remove/de-select them from where they were synced from on your computer and re-syncing e.g. to remove a synced folder de-select that folder on the Photos tab and re-sync, to remove all synced photos select and sync an empty folder. Depending upon what iOS version that the iPad is on, you might be able to delete all synced photos by swiping across the 'Photo Library' line in Settings > General > Usage > Photos & Camera (that should give you a Delete button but I haven't tried tapping it to see if it works).

^Help me out. Thanks.You don't have a class p2.Two, You do have a class java.p2.Two. Package paths aren't relative.
Also, it's recommended not to use package names containing "java" or "javax" (or is it illegal to do so?). Change your package & folder names.

Calling a method in the backing bean when rendering a table

I'm rendering a table that begins with :
<h:dataTable value="#{showRooms.rooms}" var="rowRoom" ...
There are several properties I'm displaying. Some are just displayed as they appear from the database like:
<h:outputText value="#{rowRoom.roomNumber}"/>
However, some I need to translate so they display a more meaningful message to the users. For example, status is stored 'A', or 'NA', but this should display 'Available' or 'Not Available'. To do this, I'm taking an idea I saw in another forum by providing a method to call and translate the text. For example:
public String getDisplayedStatus(String status) {
if (status.equals("A") {
return "Available";
} else {
My problem is how can I invoke a method and pass in the current value of status for that row in the table. I think I need something like this:
<h:outputText value="#{showRooms.getDisplayedStatus(#{rowRoom.roomStatus})"/>
But that doesn't work. I can invoke the getDisplayedStatus method when passing in a hardcoded parameter, but it won't translate the value of both expressions(the method and the method param). How can I achieve this?
Thanks,
Mike

Yes. I've done that and it does work....sort of. It works as long as I refer to it as 'displayStatus'. It looks up the getDisplayStatus and returns a value. The problem is getting the current status value from the object in the List. For example, the 3rd row in the table has either 'A;' or 'NA' for status. I need to know this value in order to do my translation. The way I see it, I either need
1.)a way to call a method on the backing bean and pass the value of status from the current row into the method.
-or-
2.)in getDisplayStatus, I need a way to access the current row's value, perhaps through an expression. This appears to be what you can do in the AbstractPageBean class that all backing beans inherit in Studio Creator. I've seen code in a getter like 'getValue(#{currentRow.status}'), but I don't know how that is done. I looked for the source to AbstractPageBean on the web but couldn't find it - maybe its not open-source.
Anyway, please share if anyone has a solution. I'm sure this has been done before.
Thanks,
Mike

How to call an action when the user selects a radiobutton

Hai
PLease help me in providing the information.
In my Project i have two radio buttons as
New
Asssessment
when the user selects new button, i want to automatically call an action in the controller(.jpf file)
Simalarly when he selects the other radio button i need to call a separate action in the controller.
Remember i dont have the submit button.
I want to dynamically call an action when the user selects the radio button.
i dont have any field inthe radio button which actually takes action as an attribute .
please provide me the necessary

Hi,
You can use JavaScript to call the action in interest upon the Radio Button Element Being Selected.Should be simple, and if your controller is part of the portlet dont forget to use the jpfScopeId to asscoiate the controller instance with the one in the portlet.
Let me know if you have any further questions.

Calling a method in the Custom ADF component from JSF page

HI.
I have created some custom compoents by extending the core ADF Components. Like i have a ComboBoxDefault component with it's ComboBoxDefaultTag.java and Controls.tld file.
Now my requirement is i want to bind my label to this component from the JSF page. like
<fwcontrols:label binding="#{listComponents.comboBoxDefaultLabel}" id="label1"/>
<fwcontrols:comboBoxDefault binding="#{listComponents.cmbLocales}"
value="en_GB" id="comboBoxDefault" autoSubmit="true" label="label1">
<f:selectItems value="#{listComponents.locales}"/>
</fwcontrols:comboBoxDefault>
In my JSF page the label will have an id, and that id will be specified in the label tag of the component.
In Tag.java file i have overrided the setProperty(FacesBean facesBean). In this method i have bind all my properties. In core JSF the setProperty method is provided with the UIComponent parameter, so i can call my method in component also. Which is not in case of ADF Faces.
My main point is how i can call my method setLabel() which is in ComboBoxDefault.java so that i can set the label.
Thanks in Advance.

Thanks for all your replies. I want this kind of a functionality because Im trying to invove a DC (Child DC) from a Parent DC such that the Child DC's view is displayed onto the view container of the Parent DC. I have embedded using 'interface view of a component instance' in the Parent Window and am able to create the component and set usage though the onPlugDefault of the Child View.
But I observe that when i make a call from the parent, the flow is like this:
1. The wdDoInit of the Child Component Controller gets triggered first.
2. Then the wdDoInit of the Child's VIEW gets triggered
3. and THEN the onPlugDefault of the Child Component Interface View
What I had actually wanted was to Fire onPlugDefault where Im calling a method LoadData(), after which the Child DC's view must be triggered so it can display the fetched data.
What is actually happening is the view gets displayed, but no data is displayed in the view.
Right now I have just given a work around where Im triggering LoadData() of the COmponent COntroller from the wdDoInit of the VIEW.
Is there a better way to do this? I find it strange that I have to load the Data from the view.
Thanks
Jack

Go to sm37 - double click on the job that was failed - Click on Step (on application tool bar) to get the program name - double click on the program name - new popup will be opened - then copy the program and variant
Go to se38 - enter the program - execute (F8) - choose the variant that is there in the background job - run in forground first
if the run is good - then check the program - SE38 - Display the program then see
I just saw the above message BD87... .if that is true, you dont have to do all these
I dont think it is possible to schedule a job with BD87. Is this the first time or is any job completed without errors for this?

How would I call a method inside a dll?

How would I call a method inside a dll? Is it even possible in Java? Like in VB you would do something like this: XXX.dll --> XXX.Activate()... I have already loaded the dll like this:
String xxx = "C:/WINDOWS/system32/xxx.dll";
System.load(xxx);
Please help?
THX

I've got another question.
I've gone through the link you posted and a couple others that I found.
I am able to create an interface using the windows kernel32.dll and go through an example I found.
But when I try to use a dll that I have from another application, I have problems.
Here is what I have for the interface.
public interface IAiCamDeviceControl extends StdCallLibrary {
     public IAiCamDeviceControl INSTANCE=(IAiCamDeviceControl)Native.loadLibrary("D:\\IAiCamDeviceControl.dll",IAiCamDeviceControl.class);
//        public long GetVersion( String s );
//        public long Close();
}The interface that works looks like this:
public interface Kernel32 extends StdCallLibrary {
     public Kernel32 INSTANCE=(Kernel32)Native.loadLibrary("Kernel32",Kernel32.class);I thought that the problem might be using the path name for the library, so I copied it into the system32 directory.
Still get the same error:
Exception in thread "main" java.lang.UnsatisfiedLinkError: Unable to load library 'D:\IAiCamDeviceControl.dll': The specified module could not be found.
My main looks like
public class Main {
    public static void main(String[] args) {
//          Kernel32 lib=Kernel32.INSTANCE;
//          Kernel32.SYSTEM_POWER_STATUS batteryStatus=new Kernel32.SYSTEM_POWER_STATUS();
//          lib.GetSystemPowerStatus(batteryStatus);
//          System.out.println(batteryStatus);
            IAiCamDeviceControl camDev = IAiCamDeviceControl.INSTANCE;
}The commented part is from the version that worked.
All I attempted to do here was just create an instance of the interface.
Any idea why I can't access the dll?
The dll is the same one that is used successfully in VB, C#, and C++ demo programs, so I suspect it is a good dll.
