Application.invokeLater (Runnable) in Focus event handlers

Several code examples use Application.invokeLater (Runnable) in onFocus and onUnfocus methods:

protected void onUnfocus() {}

-For example, a user rolling the trackball / slips the trackpad and the system decides that it is time to activate another area.  At this point, the system checks and invokes all sorts of methods - one of them is Field.removeFocus () that must call onUnfocus() in this area. If unUnfocus() is called when the system is not yet completed this transfer of focus. It might not be all-terrain with focus, just a 'right' to receive the focus.

Or take the case when a new screen is pushed. This new screen has not been painted yet, the system has not yet checked if she has any field focusable, etc. - but your onUnfocus() is already known. Is it not strange that you'd better to be careful and annex an action after the dust has settled offshore?

  • Application.invokeLater () and event queue size limit

    Analysis of Application.invokeLater () is insufficient. He mentions a "size limit" of the queue of the event but never defines it or said if it is always applied. Therefore, the contract is ambiguous.

    I would really like to know:

    1. am I guaranteed that an executable that I turn to Application.invokeLater () will eventually race, if the event thread doesn't die?

    2. What is the size limit of the event queue and it's always enfoced or only when the event thread did not intervene?

    3 - How is applied the limit? Runnables get just dropped from the back of the queue and nothing happens?

    I tried.

    The platform throws an exception and judge of the application to be unresponsive not once you have planned a not-very-large number of runnables.

    It is a pity that this is not documented and it is a pity that the queue is so short. Now I have to have a queue in my code to avoid this situation.

  • Creating ent via API and post processing event handlers

    I have a number of post-processing-event handlers defined for the creation of the organization. They all work fine and do what they need to do when I create an organization via the web interface. However if I create an organization that uses the Java API, managers of events do not run. They are not supposed to run? I think that IOM should handle all the same applications - everywhere where they are generated.

    Here is my example of API:

    Import Thor.API.Exceptions.tcAPlException;
    Import Thor.API.Operations.tcOrganizationOperationslntf;
    import java.util.Hashtable;
    import java.util.HashMap;
    Import javax.security.auth.login.LoginException;
    Import oracle.iam. platform. OIMClient;

    public class test {}
    Public Shared Sub main (string [] args)
    {
    Hashtable env = new HashtableQ;
    approx. put (0IMc1 I ent. jAvA_NAMING_FACTORY_INITIAL, "weblogic.jndi.WLInitiialContextFactory");
    env.put (mpta OIMC]. JAVA_NAMING_PROVIDER_URL, "t3: / / localhost:14000");
    OIMClient oimclient = new olMClient (env);
    try {}
    oimclient. Login ("xelsysadm", args [O] .tocharArrayO); II the password is the only argument
    } catch (System.Exception e)
    System.out.println ("ERROR: connection exception.") Please check your username / password are correct. ») ;
    }
    tcorganizationOperationsintf orgManager = (tcOrganizationOperationsintf.class) oimclient.getservice;
    < String, String > HashMap hmorgDetails = new HashMap < String, String > ();
    hmOrgDetails.put ('Organizations.organizationName', 'org test');
    hmorgDetails.put ('Organizations.Type', 'Branch')
    Try
    {
    orgManager.createOrganization (hmorgDetails);
    } catch (Exception e) {}
    System.out.println (e. getMessage())
    e.printStackTraceQ;
    }
    return;
    }
    }

    Try to use OrganizationManager service class in your java code instead of the tcOrganizationOperationsIntf inheritance. Which should trigger the event handler. Recently, I had a problem where using the EntityManager on user has not triggered the eventhandler but only when using the UserManager triggered it.
    It would be possible only when you are using the legacy API, a new orchestration is not produced, and therefore the event handler is not called.

  • Do I need to worry about these event handlers in a grid in a perspective of memory leak?

    I'm pretty new to Flex and could not understand how to add event handlers for components of rendering engine inline article since the script file so that I have attached the listnerers just under the elements themselves (for example < mx:Checkbox... change = "outerDocument.doSomething (event)"... / > "):

                   <mx:HBox width="100%" height="100%" horizontalAlign="center">
                        <mx:CheckBox id="targetCheckBox" selected="{data.@isSelected == 'true'}" 
                             change="outerDocument.checkChangeHandler(event);"/>
                        <mx:Image horizontalAlign="center" toolTip="Delete" source="@Embed('/assets/icons/delete.png')" useHandCursor="true" buttonMode="true"

                             click="outerDocument.editHandler(event);"/>
                   </mx:HBox>

              <mx:DataGridColumn id="Created" width="140" dataField="@createDateTime" headerText="Created"  labelFunction="UiHelper.gridDateFormat" />
         </mx:columns>
    </mx:DataGrid>

    This grid is part of a display which will be destroyed and re-created potentially several times during the session of a user of the application (there's a great dynamism to the app and views are created running). Destroyed by I mean the view that contains the DataGrid above will be is more referenced in some circumstances and a whole new object view is created (which means old datagrid is more referenced and a new one is created).

    I heard that you must clean up event handlers, when they are no longer used, and I know how the view is destroyed, but I do not know how to clean the point added to the renderer components managers event? Is this something that the Flex garbage collector handles effectively?

    In addition, on a somewhat related note, how could I push the element converter to an external component because I need a reference to the datagrid.selectedIndex who, as an external element rendering that I wouldn't have access to this grid containing in my event handlers for the rendering engine option buttons?

    Let's be careful here.  It is true that the cleaning is not necessary, but in the

    provided code snippet, outerDocument is implied to be a .mxml that

    contains the DataGrid control and its components online references because of

    the rendering engine are a function in a script that is not defined in block

    the DataGrid control.

    Although the outerDocument is not destroyed and only the renderers are underway

    created and destroyed, the written code will not cause a leak because the

    rendering made reference to the outerDocument and not the opposite engine.

    And it's because the code in an event handler block is not a request of

    Add an event listener to outerDocument, it is simply a method of a body

    the handler that is attached to an object in the rendering engine.

    What would cause a leak is a call to outerDocument.addEventListener.

  • Event handlers 11gR2PS3 IOM raises but does not commit any changes

    Hello

    We have developed a few EventHandlers that triggers events RoleUser (MODIFY, CREATE, DELETE). An eventHandler does the following:
    -Gets the role that have been added to a user
    -Detects the role information
    -Updates the user with the role to some UDF information

    This feature works fine on its own when only an EventHandler is defined - there is not when having several of the handlers defined in the same time. This seems very strange for us, as some features do not work when this unfortunate error occurs.

    These are the ones we have now:

    Newspapers are populated and APPARENTLY the IOM user is updated (populated UDF and our own newspapers and oracle logs shows that the user object is updated [using the UserManager]), but when you look in the database, nothing happens. No update after all the UDF. It's quite strange and we do not quite understand the EventHandlers point if they cannot live together like that...

    Anyone who has experienced similar problems? Its quite frustrating and chasing a fake bug as it's pretty boring.

    Kind regards

    EIS,

    This has been resolved now. It seems to be related to this Bug:

    https://support.Oracle.com/epmos/faces/BugDisplay?_afrLoop=544812021641634&parent=SrDetailText&SourceID=3-11573477441&ID=11804355&_afrWindowMode=0&_adf.CTRL-State=lmefs64q2_81

    As indicated in the bug, a new orchestration runs and causing the initial EventHandler that triggered, say UserManager.modify (), to stall PENDING - even if there is nothing to be waiting on. The fix pertains to adding the following lines of code:

    try {
    ContextManager. pushContext (role.getKey (), ContextManager.ContextTypes. ADMIN, OimContextProperties. ( ROLE_GRANT) ;
    roleManager.updateRoleGrant (role.getKey (), long of . toString(user.getKey ()), attributes);
    } catch (ValidationFailedException |) NoSuchRoleGrantException | RoleGrantUpdateException e) {}

    ...
    } { finally
    ContextManager. popContext ();

  • Event handlers and the question of access to IOM 11.1.1.5 policy

    Hello

    IOM 11.1.1.5

    We created the Post process event handlers to fill some fields on the user form.
    We created an access policy to configure the AD resource to the user.
    We had used the cards to prepopulate to fill in the form process AD.

    Now, as a user is created through reconciliation:
    (1) user is created at the IOM.
    (2) handlers process events post generates fields (name common example seen on balls)
    (3) access policy triggers and using prepopulate adapters process form is filled
    (4) fields like first name, last name are entered on the form of courses
    (5) the fields that are generated by using common name event handlers are filled under vacuum in the form of courses.

    Reason is that, before the common name is saved on the user (generated by the event handler) form access policy is drawn and prepopulate the recalled adapters and resources is put into service.

    How can I ensure that fires after access policy fields are recorded on the form user generated by post process event handlers.

    Yes, you need a different order for diff eventhandler. But preprocessing and postprocessing can have the same

    for example pre eventhandler-1003, 1005
    post eventhandler may also have some 1003,1005

    but you can't put even in order in the same type of eventhandler

  • Doubts about event handlers

    Hello

    I had some doubts about the event handlers in the IOM 11.1.1.5...

    (1) I want to use the same event handler for the message insert and update Post task... Can I use the same handler for this... If Yes, then how can I make...

    (2) can I create the single class of Plugin.xml and add all the jar files in IE single lib folder and zip them all together... If yes then what changes I need to do? Need only add that the plugin tags for different class in the plugin.xml file files? OR need to do something extra too...?

    (3) if I need to change something in any class handler... Is it need to unregister the plugin and register again...?
    If Yes... Is it need to delete the event handler using the weblogicDeleteMetadata command?

    (4) that we import the event handler of the path as event manager/db /... If we add all the evetn handler.xml files in this folder... As when importing weblogicImportMetadata called recursively all files in this folder... Now, if I need to change anything in one of the event handler class... so if import us from the same event manager/db folder... What to do... Create the copy of the eventhandlers? OR should I not add Eventhandler.xml files to class files, I made the changes...

    (5) given that I need to create emails on the creation of the user while recon and identification of email updated as a first name or surname updates... I had to use in the event handler.xml (entity-type = 'User' operation = "CRΘER") or something else...


    Help me clarify my doubts...

    Yes, on the update post you need to be check first if the first and last name change to update the mail electronic id, rather then calculation always email identification. So, you can check the path name are updated through the previous code.

    Also, if I were to move the listener to drain directly into the clip where the button, how could I make reference to the parent/parent timeline (the main timeline)? Am I right to understand that .This refers only to the current clip?

    Thank you!

    You can place your code in a function that is called when your objects exist.

  • Movie Clip event handler block button event handlers

    Hello - really need help!

    I have a clip that contains a button. (i.e. my_mc.my_btn)

    I have a few event handlers for the clip (my_mc.onRollOut, my_mc.onRelease, etc.) and that they are working correctly.

    However, once I added these event handlers to deal with the clip, my breast my quit clip buttons all work together. It's like movie clip managers are overridding the functionality of the button.

    How to use movie clip handlers and my buttons inside continue to work?

    Help!

    You're right, manifestations of the parent are the substitution or fly, the events of the nested children. See this article for ways to deal with this: http://www.senocular.com/flash/tutorials/buttoncapturing/.

  • Management events JFXPanel drag a expensive impact on performance with event handlers

    We have a drag event handler, which is a bit expensive, takes something like 20 ms. However, the code must be run synchronously.

    Is no problem in a pure environment of JavaFX, less events drag are created when the CPU load is high.

    However, when they are incorporated in the Swing using JFXPanel, this adaptation doesn't kick in, many events drag is created and the application become slow.

    Is it possible to imitate what JavaFX in the JFXPanel scenario?

    The code below is a stand-alone example that shows what I'm describing.

    Some results I got:

    -eventHandlerSleep = 5 - noswing-128 events > drag

    -eventHandlerSleep = 30 - noswing - > 46 events drag

    -eventHandlerSleep = 5-> 136 events drag

    -eventHandlerSleep = 30-> 135 events drag

    Yes, it is a known problem or expected, even if I don't remember the JavaFX bugs filed on this issue. JFXPanel is known to have some different problems with the sending of the event, such as Swing and live JavaFX on two threads. Drag-and - drop are required to be synchronous, so we enter a nested event loop while sending events to the Swing DND to JavaFX. It is the source of performance issues that you observe.
