Stop the flow of task by program activity

Hi all

I use 11 GR 1 material ADF Faces

I made a method I call whenever an exception is thrown in the controlled beans. It is a way to show all runtime exceptions in a dialog without forwarding to a default error page. I use FacesMessages to show the errors of the dialog box.

But I have a problem/question. If I press a button with ActionListener and Action, and an exception is thrown in the method executed by the ActionListener, how can I do to stop the implementation of the Action? This is because the popup informing them that an error has been produced, is raised me in the next page, called by the Action.

Here is the code:

1. press on a button that executes this method raised a NullPointerException:

* public void doNullPoiner3 (ActionEvent actionEvent) {*}
try {}
System.out.println ("put a message with id");
String s = null;
System.out.println (s.Substring (0));
} catch (Throwable e) {}
CustomExceptionHandler.reportTechnicalException (th, "it1");
}
*}*

2. the code of reportTechnicalException()

* public static void reportTechnicalException (Throwable th String idField) {*}

retry the custom messages (overview and detail)
...
Show the error
addFacesErrorMessage (summary, detail, idField, FacesMessage.SEVERITY_ERROR);

*}*

* private static void addFacesErrorMessage (String summary, String msg, String stId, gravity javax.faces.application.FacesMessage.Severity) {*}

FacesContext ctx = getFacesContext();

FacesMessage fm = new FacesMessage (severity, summary, msg);
String stViewComponentId = (stId! = null & & findComponent (stId))? stId:null;

ctx.addMessage (stViewComponentId, fm);

*}*

Please, can you help me? I only want to stop the execution of the workflow if it exists.

Thank you in advance,
XAVI.

Hello

Having the action listener throw an AbortProcessingException. This is an exception of reserved JSF that prevent the propagation of the event without killing the application.

  • Document Word has stopped the flow manual

    I'm a newbie to InDesign, moved an old document in InDesign and of course, PageMaker on a deadline. My Word text was flowing very well, but has stopped. I see that the link seems to have become not related. Don't know what to do now. Don't want to start over. My InDesign CS3 Visual Quickstart Guide is not of any help. (Mac 10.4, Word 2004)

    When the textflow stops in the middle of a file Word usually has something in the Word file, InDesign does not like. You go back to the Word file, to the point where it ceases to flow, and change it (view all invisible characters in Word to see what is the cause) so he can continue to flow.

  • How to stop the monitor go black after no activity for a short time during the reading of a document?

    When I read an email or document without moving my mouse, the screen turns black after only about a minute and then proceeds to my screensaver.  I have to move the mouse constantly opening my active window.  I can't find out how to disable this "Energy Saving" so I can read the lengthy articles without being interrupted every other minute.  This was VERY irritating!

    Hello

    Open windows control panel, open personalization, click on the link to screensaver at the bottom right and in the next window, set the time in the area of 'Wait' for once you want before the screen saver appears, and click on apply. Or if you never get the logon screen, remove the check mark next to of "on resume, display the login page»  Click on apply to save the changes.

    Then open windows control panel again and click on Power Options, click Change plan settings next to your current power plan selected in the next window, set the time using the drop-down list next to "Turn wide Display" to a more acceptable level and then click on save changes.

    Note:  Set in the Options menu of food to be slightly longer than the time set in the Menu of the screen saver or you will never see your screen saver start.

  • Set initial focus point in the middle of several models, the flow of tasks and fragments.

    Hi guys,.

    With the help of JDev 11.1.1.4.

    I've got the fragments of the page for which I would like to set the initial focus. The problem is that, often, these pages of .jsff are nested in page templates, model train, dynamic regions, etc. AFAIK, the original goal of a component is on the document. The trick is to find what all the prefixes are before the .jsff component.
    pt1:dynamicRegion:3:pt1:t1:0:it1
    Y at - it an easy way to understand all of the prefixes before that: it1, which can often be radically different?

    The easiest way would be to set the initial focus to say "defaultFocus" and have each .jsff has a component id called "defaultFocus? Feels like cheating, but any other way I can think seems much too complicated.

    Thank you

  • I want to stop the flow of particles?

    Hello, I do a particle 'Especially' system but I have a question, when I play the particles, the particles start from nothing and then they continue to be driven until the end (default) but I want somehow 'freeze' the particles in order to animate manually, because I want to move the particles slowly since I do a simulation of ashes I want to know how can I maintain the particles yet so I need to use only these particles (not not with the freezing of the image) for I can be able to change the settings on the timeline.

    Help, please!

    You cannot change the properties of the particles on the fly. attributes such as battery life, speed, etc. are determined on emissions and evaluated in combination with different graphics and gradients and other parameters. You can 'freeze' simulation with physical time parameter, but you cannot change any of these properties for the already born particles. If a particle born after retouching you life may have a different life expectancy, but not one already in your stream.

  • problem on the flow of tasks of adf and dynamic region

    JDeveloper 11.1.1.5

    I created a page jspx for making fun of the home page.

    In the facet of the beginning, there are 2 Ref order link in the region (for the 2 workflow)
    In the facet of the Center, there is a dynamic region. Once you click on the order link, the region will be changed.

    The problem is:

    the workflow has 3 displays (View1-> 2-> the View3), if I run mode 2, when I click on the link even in the facet of the beginning, it does not refer to the View1.

    I want the page back to View1 when I click the link, how can I apply?

    Hello

    You must reload the region to start again. To do this, you can assign to the refreshCondition for connection of the region, in such a way that when it is resolved to true, the region will be reset. No doubt, you can add a parameter to the region and set its value through setActionListener for the click on the link.

    I use a way workflow for the destination server.

    Kind regards

    before you stop your workflow process, you need to calm down activities to bodies (Source and Destination).
    Once that there is no activity, I normally stop the work of the heart rate (if you have one), stop the Capture, arrest the spread and stop applying.
    You can use OEM or have your scripts and run as user admin of streams.

  • How to stop the water flow?

    Hello

    I need to make the water from the shower, when you click on shower.

    And the water should stop after 5 seconds.

    The code is below.

    Water flows well. But I fail to stop it.

    I added a timer that starts when the shower is clicked. And must stop the flow of water after 5 seconds have elapsed.

    With the lines

    If (stop = true)

    {

    break;

    trace ("Break");

    }

    It looks like the for loop breaks right from the start, from the first second. But not completely, somehow 1 or 2 drops are fluid.

    Without these lines, nothing happens when the time is up (5 seconds click on the shower). The water just flows.

    Can anyone help? How to stop water flowing after 5 seconds and cleaning of the table and stage of water drops?

    Thanks in advance!

  • Workflow code example need to stop the treatment when the violation occurred at the time of booking

    Hello!

    I intend to create our own order workflow in a seeded workflow that will include an activity that stops the workflow itself, if a violation was committed at the time of booking. Violation may be some thing as if the order date is more 10 days already at the date of the day, she must indicate the message "order is already spent the days allocated for the booking of an order". Probably a raise form_trigger_failure will be used to stop the flow of work.

    If anyone can be good enough to show me a few codes for this task.

    Thank you.

    Jon

    That's what we did for a similar requirement:

    1. create a copy of the workflow for order OEOH header

    2. create a custom procedure that checks your commits, add messages and returns either a pass or do not have the workflow

    3. create a workflow process that calls the new procedure

    4. place the new process after the eligible book.  The current passes should go to the book stage, the flow of failure should return to eligible book

    5. replace your workflow to header current order by your new custom in oe transaction type settings.

    I couldn't attach a code sample.
