How can I call a support bean taskflow method?

Build JDEVADF_11.1.1.3.PS2_GENERIC_100408.2356.5660

I like to call a method (taskflow) back bean!

my bean code:
    public void imageLinkActionListner(ActionEvent actionEvent) {
        String              id      = actionEvent.getComponent().getId();
        int                 linkID  = Integer.parseInt(id.substring(4));
        DCBindingContainer  bc      = (DCBindingContainer)ADFUtils.getBindingContainer();
        DCTaskFlowBinding   tf      = null;
        
        System.out.println("Region Change...."+id+" INT "+linkID);
        switch (linkID) {
            case LINK_CALENDAR_REGION:
                tf = (DCTaskFlowBinding)bc.findExecutableBinding("calendartaskflowPage");                    
            break;
            case LINK_MAIL_REGION:
                tf = (DCTaskFlowBinding)bc.findExecutableBinding("mailtaskflowPage");                    
            break;
          case LINK_ADDRESS_REGION:
              tf = (DCTaskFlowBinding)bc.findExecutableBinding("addresstaskflowPage");                    
          break;
          case LINK_BLOGS_REGION:
              tf = (DCTaskFlowBinding)bc.findExecutableBinding("blogstaskflowPage");                    
          break;
          case LINK_MAPS_REGION:
              tf = (DCTaskFlowBinding)bc.findExecutableBinding("mapstaskflowPage");                    
          break;
        default:
            return;
        }
        if (tf != null){
            uiMainRegion.setRegionModel(tf.getRegionModel());
            uiMainRegion.setValue(tf.getRegionModel());
            tf.getExecutableBindings();
            AdfFacesContext.getCurrentInstance().addPartialTarget(uiMainRegion);
        }
        
    }
I like to call * #{backingBeanScope.mapBean.initMap} *.
My taskflow source
<?xml version="1.0" encoding="windows-1252" ?>
<adfc-config xmlns="http://xmlns.oracle.com/adf/controller" version="1.2">

      <outcome id="__7">
        <fixed-outcome>init</fixed-outcome>
      </outcome>
    </method-call>
    <control-flow-rule id="__2">
      <from-activity-id id="__3">initMap</from-activity-id>
      <control-flow-case id="__5">

      </control-flow-case>
    </control-flow-rule>

Hello

call the bean, the EL in Java using #{backingBeanScope.mapBean.initMap} as an expression of the reference method. If you try and go directly to the bean then chances are that the instance is unavailable. EL in Java using always ensures that

  • How can I call a stage, which is in a sous-suite, of a different sous-suite

    Hi, could someone me, please?

    How can I call a stage, which is in a sous-suite, of a different sous-suite.

    For example:

    Two sub sequence, is called, it is called B. In the order B, there is a step called BStep.

    In a sequence, there is a stage called AStep.

    Now, I Hope AStep can I call BStep, how can I do?

    Thank you in advance!

    Allan,

    What you're asking to do is not a practice of good software.  That's like saying you want to call a single line of code into a DLL.

    The best way to do what you want is to put the steps in a 3rd sous-suite.  Then set the subsequence with the parameters of the step.  Then call this subsequence of a sequence and the sequence B 3rd.

    This way, whenever you update the stage, they both get changes.

    Hope this helps,

  • Installer wrongly claims that it is software counterfeit. I paid for it. How can I contact customer support to fix this?

    EXECUTIVE SUMMARY

    Installer says it is counterfeit software, but is not - how can I get customer support for this problem?

    DETAILS

    On installation of creative suite master collection cs6, the installer says "the product you want to install is not a real software from adobe and seems to be counterfeit. Please report a piracy or contact customer support for assistance. Needless to say that the product is genuine and legitimate. I teach at a University, and I bought a perpetual license for it in 2013. I installed it on my laptop then. I now have a new laptop and installed it on the new. I did not disable the old one because I need to keep at least one that works. Help Adobe says 'one license for Adobe software allows you to install an application on two computers,' which is what I do. The serial number has been validated as correct. The link 'contact customer support for assistance' sending me on this forum, rather than to a real customer support representative. Detection of piracy hits a false positive that annoys a real customer. How can I contact someone who can verify the legitimacy of my account and solve this problem? Thank you.

    Thank you. The pointer finally got someone in a live chat. They suggested that perhaps my install files were corrupt. They were not able to provide the correct hash values (which would have allowed me to check if my files were corrupt or not without having to re - download them) so my only recourse is to download some 10 GB of Adobe and see if that fixes it. I do as we speak, and meanwhile I'll go to bed.

  • I have a licensed version of PhotoShop CS5 and bought a CS6 upgrade.   When I update, it says invalid license id.   What to do next?  How can I contact personal support?

    I have a licensed version of PhotoShop CS5 and bought a CS6 upgrade.   When I update, it says invalid license id.   What to do next?  How can I contact personal support?

    Hi David,

    You must download Photoshop CS6 and enter the serial number for Photoshop CS6 and then you will be prompted to enter the serial number of product qualification.

    Enter the serial number CS5 to install and activate Photoshop CS5 on your machine.

    Please post on the Adobe Forums.

  • How can I call Save as dialog box before you download pdf files?

    How can I call Save as dialog box before you download pdf files?

    Here's my favorite scenario:

    1. the user clicks on the button

    2 Save as dialog box displays

    3. the user chooses the place

    4. a set of PDF files download here OR download a single zip file

    Background:

    I want to ensure that the user sees that the files are downloaded. I'm content to users who are not Web warned.

    Concern:

    1. the user has no idea how to find the downloaded files or files have even downloaded.

    2. I would like to deliver all in the form of zip files. Not sure if the automatic opening of zip files still exist.

    FOR INFO:

    I use jQuery UI buttons. Not sure if that factors in the response.

    Just for clarity, I'm not forcing a download. The user will click on a button.

    Click on a button or click on a link, either way you are technically running a script to force a download.

    I guess that's the PHP on the server.

    Yes but it is only a part of it.  Once the form runs, another script is called that opens the browser download dialog.

    Y at - it a php script to call the open/save dialog box?

    Yes.

    
    

    Name this file zip2download.php.

    Add a link to your HTML page:

    zip2download.php">Download the Zip
