• Communication of contextual events between BTF

  Is it possible to have contextual events is based on communication between two defined task flow consumed in a single page.
  
  Note that its not from a page to a TF and or a TF to a page. I went through all the oracle Insider videos, this one I couldn't find it. I am looking for the communication of contextual events in function between two BTF consumed in a single jspx.
  
  Appreciate help on this.

  Hello

  Is it possible to have contextual events is based on communication between two defined task flow consumed in a single page.

  Yes.

  Its the same facility if you communicate from a page to a workflow. The Subscriber and receiver are mapped to the file page pageDef container (declaratively as insider ADF video)

• How to raise a contextual event commandMenuItem

  Hi all, I use Jdev 11.1.1.7 I have a workflow bounded containing a page with af:menu and a commandMenuItem the taskflow bounded is called by a parent taskflow on any element of command menu selection I need some settings back to appellant taskflow. That's why I planning to trigger contextual events on the actionListener to the command menu item. Please let me know if this is correct or if there is no doc who could be referred to achieve. Thanks, Asha

  Contextual events are based on adf link layer if you need 'something' in pageDef, which can produce events (and 'something' in an another pageDef to consume events).

  You may create beans DC and call the method thereof for products/consume the events.

  See also these examples:

  http://www.jobinesh.com/2009/07/programmatically-publishing-contextual.html

  Binary: Outbreak of Navigation from a contextual event handler method

  Or you can spend a few bean managed as BTF input parameter and set the settings back there...

  Or you can use DC Bean that is shared between taskflows...

• Post a contextual event on disclosure - jdev 11.1.2.3 tab

  Hello:
  
  I need to post a contextual event when a component in PanelTabbed (ShowDetailItem) tab is disclosed.
  
  In each tab, there is a stubborn workflow fell as a static region. Open tabs are defined only to be "active".
  
  The published contextual event is consumed in the BTF fell as a region to the ShowDetailItem of the tab.
  
  How declaritively or publish the contextual event to disclose the tab?
  
  Code or section of sample references would be greatly appreciated.
  
  Thank you.

  Hello

  eventProducer is the method name of the producer.

  You need a) create this method as a method of producer
  (b) create DataControl
  (c) add to the jsff where you want to trigger the event.

  You can see the blog below.
  http://www.jobinesh.com/2009/07/programmatically-publishing-contextual.html

  You can download the workspace that explains
  (1) create producer method, data control EventProducer. Put the producer method on task.jsff
  (2) (2) creer create consumer method, data control consumer event.

  Then goto main.jspx where the event has been subscribed.
  Check-in mainPageDef.xml--> ContextualEvents event Publisher.

  To raise the event, you can see Task.java

          DCBindingContainer bc =
              (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
          JUCtrlActionBinding actionBnd =
              (JUCtrlActionBinding)bc.getControlBinding("produceMessage");
          System.out.println("Producer : Programmatic Invokation !");
          ((DCBindingContainer)bc).getEventDispatcher().queueEvent(actionBnd.getEventProducer(),
                                                                   "Hello, Did you call me?");
          ((DCBindingContainer)bc).getEventDispatcher().processContextualEvents();

• Problems with the stubborn workflow

  Hi all
  
  I'm having some trouble with the stubborn workflow. I created the parameters of entry and exit on the workflow and I can't make them work.
  
  Version: 11.1.1.4
  
  Here is my scenario:
  
  1. I created a display on the adf-config to use as my home page
  2. I created two points of view on flows of different delimited tasks two (one for data on employees - a table and one to show the details of the Department - a form)
  3. I dropped two workflows bounded as areas on my main page
  4. I wanted to click on the employee in the area of the employee id and pass the service id in the region of the Department
  5. I converted my employee_id rank to a link and added property inspector set so that I could capture the value of line department id
  6 configure the parameters input and output both bounded task flows (the employee) and pronounce on the Department.
  
  
  However, the value does not seem to the Department defined in the workflow... or so it seems. I'm sure it's user error I'm not sure what I'm doing wrong.
  
  Any suggestions or advice would be appreciated. Are there good ways to see if the values of the parameters are ongoing value and actually passed (as step via the stream in any way and see if my #{pageFlowScope.) Param} is ready?
  
  Thanks as always!

  I guess you need to pass the parameters in a contextual event. The flow of work in the region begins, but normally doesn't end, if you do not get an output parameter.

  Here are some links:

• The use of contextual events to rynefall a model piloted by LOV

  ADF 11gpatchSet1
  
  Hello
  I have the following Setup.
  
  A homepage containing a region.
  In the area there is a table.
  The contents of the table can be changed in a popUp.
  One of the fields in the pop-up window is a selectOneChoice based on a template
  Driven LOV.
  The research used for the LOV table can be changed via a stubborn workflow
  called from the homepage via a command menu item.
  
  What I have to do is to update the query used for the LOV after the stubborn workflow has been
  called.
  
  I looked at contextual events, but I don't know how to close the loop.
  I created an event on the main page to which the region application module is a Subscriber.
  I've added a command button to produce the event and when the button is clicked the
  application of the region (the Subscriber) module receives the event.
  I must now do the same once the stubborn workflow closes, but I'm not
  sure how.
  
  Any body any ideas?
  
  Concerning
  Paul

  Hello

  the stubborn workflow, called in a region, or using an actiity of taskflow appeal? In the first case, a navigation region receiver could be used which detects the closure of the workflow by its viewId null. If you use a workflow activity call, then you might have a method activity that you call upon the return of the workflow. I don't know that you need a contextual event for that.

• programmatic contextual event does not post for first click

  Dear all,

  I use Jdev 12.1.2.

  In my case, I have 2 tabs, Tab1 and Tab2. I bounded 2 TF Tab1 and Tab2.

  When you click on the GotoTab2 button, must open Tab2. what I realized using this link https://tompeez.wordpress.com/2014/09/25/jdev-12-1-3-using-parent-action-to-navigate-tabs-of-a-afpaneltabbed-from-inside....

  
  

  Now I have to send some data during the click on the button for this, I use programmatic contextual events. It's works for the second click, many times it's incompatible.

  
  

  It is code for the event during the click on edition link.

  
  

  JUEventBinding = eventBinding

  (JUEventBinding) BindingContext.getCurrent () .getCurrentBindingsEntry () .get ("eventBinding");

  EventDispatcher = eventDispatcher

  (BindingContext.getCurrent () .getCurrentBindingsEntry ()) .getEventDispatcher ((DCBindingContainer));

  Support useful subject = 'Test '.

  eventDispatcher.queueEvent (eventBinding, payload);

  And the consumer code is as below.

  {} public void filterBytestData (object load)

  System.out.println("---iRNum---"+Payload);

  String testData = load (String);

  AdfFacesContext adfFacesContext = AdfFacesContext.getCurrentInstance ();

  Card pageflowScope = adfFacesContext.getPageFlowScope ();

  pageflowScope.put ("testData", testData);

  }

  And I traced the consumer and his editor in the Test.jsf page for the two regions.

  Am I missing something here, please suggest.

  Thank you

  Able to get it resolved with my colleagues help.

  I had 2 workflow in the PSF page. for the 2nd tab I had task flow as 'deferred' which initializes the workflow, only when the tab is opened. I changed it to immediate, which will initialize the taskflow immediately. It works fine now.

• The use of contextual events for < af:commandToolbarButton... >

  Hi all
  
  I use 11.1.1.7.0 jdev and I cannot upgrade to a newer version.
  
  I need to trigger an event in a region and perform actions according to him in the other. I want to use the ContextualEvent feature as has been described in here . Everything seems clear, but I stuck in how to declare the popup event.
  
  I have a < af:commandToolbarButton... > element to produce the contextual event, I can't change it to something else. "af:commandToolbarButton" isn't Behaivor - ContextualEvents inside-tab to declare a contextual event. Maybe I need to specify it in the other way, for example using an actionListener = "#{viewScope.BeanName.callToEventProducer}" and perform programmatically attempt to contextual event mounted? "
  
  
  in my code I have:
  

  <af:commandToolbarButton ... actionListener="#{BBean.commandUndoRedo}"/>

  and in the code of bean:
  

      public void commandUndoRedo(ActionEvent actionEvent) {
          BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
          JUEventBinding eventBinding = (JUEventBinding) bindings.get("undoRedoEvent");
          ActionListener al = (ActionListener)eventBinding.getListener();
          al.processAction(actionEvent);
      }

  and in taskFlow page def:
  

    <bindings>
      <eventBinding Listener="javax.faces.event.ValueChangeListener" id="undoRedoEvent">
        <events xmlns="http://xmlns.oracle.com/adfm/contextualEvent">
          <event name="undoRedoPublisherEvent"  eventType="Action Event"/>
        </events>
      </eventBinding>
    </bindings>

  and when I try to find this event in any other workflow in pageDef - links - ContextualEvents - subscribers-
  
  I don't see any "undoRedoEvent" or "undoRedoPublisherEvent".
  
  I do well?
  
  Thank you.

  Hello

  You can create A producer events

  And inside the Manager of consumer, you can get a handful of beans of region C (if it is different from A) and update only this part.

  for example.
  This would be your method of consumer (class to create + Create + Add data as the Action method on jsff control)

      public void handleRefresh(Object payLoad){
               FacesContext fctx = FacesContext.getCurrentInstance();
  
          ELContext elctx = fctx.getELContext();
          ValueExpression valExpr =
              fctx.getApplication().getExpressionFactory().createValueExpression(elctx,
                                                                                 "#{backingBeanScope.backing_}",
                                                                                 YourBeanName.class);
          YourBeanName bean = (YourBeanName)valExpr.getValue(elctx);
          bean.refreshT1();

• Contextual event consumer

  Hello

  I use JDeveloper 11.1.1.7.0.

  Then. I have a page that contains a box. The region has a contextual event that fires when the selected item in a drop-down list is changed.

  I am the consumer of the event (on the page) in a java class (which is implemented as a data control).

  My question is, how can I change the value of a value from my page and also refresh (partialTrigger) the element? (my page has a bean class)

• Refreshing data in return of a stubborn workflow (popup)

  JDeveloper 11.1.1.6

  I have a main page that calls a taskflow bounded as a popup. One of the actions is a workflow bounded to add a line in a VO that is used in the home page.

  After you add a line in the VO in the stubborn workflow, the workflow is completed. Unfortunately, the table in the home page is not updated to show the new line added.

  I tried the following techniques to update the table in the home page, without a bit of luck:

  1. Add call action to run the executewithparams in the page to refresh the VO.

  2. added run method to run executewithparams in the stubborn workflow.

  Any suggestion?

  
  Thank you.

  I don't think you should call executeQuery once again because the same view object is used on the home page and the popup.

  What are the properties of the delimited taskflow transaction to view the pop-up window? Are you sharing the data controls with the workflow calling for the popup?

  In addition, if you share the data controls, you can try to refresh the iterator binding (by table) instead, run the query again.

  	DCIteratorBinding = iterBinding
  	(DCIteratorBinding) bindingContainer.get ();
  	If (iterBinding! = null) {}
  	iterBinding.refreshIfNeeded ();
  	}

  In addition, to refresh the component af:table to close the pop-up window.

• How to pass multiple values of payload through the contextual event - jdev 11.1.2.3

  Hello:
  
  How to configure contextual events publish several values of payload?
  
  On click of a button, I'm declaritively publish a contextual event, which works very well when a single value is passed to the event handler.
  
  My event handler method has the signature of:
  eventHandler (String)
  
  But now I also have an oracle.jbo.domain.Number, so my new eventHandler looks like this:
  eventHandler (Number, String)
  
  How to pass two values during editing of the event and how to place the payload with multiple values for the new eventHandler?
  
  All article or code would be greatly appreciated.
  
  Thanks for the help.

• ADF: Can ignore us the default activity of the ADF train in the stubborn workflow. ?

  Hi all
  
  I am a newbie for ADF and JDev. Start learning about the documentation provided for the ADF, I try to create a stubborn workflow that has an element of train and every stop on the train should be activated/skippered by program. I am able to jump the train stops after reading the content provided at http://www.oracle.com/technetwork/developer-tools/adf/learnmore/82-programmatically-navigate-trains-396873.pdf.
  But I'm not able to jump to the default train stop which is the first call of the activity in my case during initialization.
  Here are the steps I followed:
  1 creating a project of viewController and created a workflow in bounded with the component train activated.
  2. added 4 displays with train component marking the first view as default activity appeal.
  3. According to the document, which I mentioned above, I've added bean managed to ignore the train stop by program files.
  
  Now when I run the workflow, I'm able to jump the number of train stops 2/3/4, but I'm not able to jump stop number 1 (first stop which is the default activity) at initialization.
  According to documents from the ADF, for a stubborn workflow must be assigned default activity that is always called first when we enter the stubborn workflow. Which means, default activity will always be called initialization of said defined workflow and never to be ignored by the program. ? Alternatively, if there is a way to jump to the default activity, so please let me know the documentation/measures to do this.
  
  Thanks in advace.

  Thanks Timo. Your idea has solved my problem. :)

  I created a new page in my workflow narrow-minded that I realized as a default activity for the workflow bounded. Then I applied the navigation via router and under certain conditions, I am now able to switch my order to my desired train stop. By this design, I can make another customization on train button(Back/Next).

• How to get the return value of the activity of the method in the stubborn workflow

  Hi all
  
  I use Jdeveloper 11 g R2 (11.1.2.3) & Weblogic 10.3.5.0
  
  I have a stubborn workflow, default activity is a call method than calling a method in the app module
  This method returns an id
  
  I need this code in my project to do something else
  Is there a way I can access the return value of the method call activity?
  
  Concerning
  Mohsen

  Set the value of return as #{{pageFlowScope.myBean.returnValue} pageFlowScope.myBean.returnValue} in the method, call the property inspector and get the value in your managed bean.

  String returnParam = (String) JSFUtil.getFromPageFlow ("returnValue");

• Triggering Validation in a region through a contextual event

  I use JDeveloper 11.1.1.6.0.
  I'll try to find how to trigger the built in validation that occurs normally when occurs a 'submit' action, but have the submit action occur outside of a region, and the validation also occurs in the region itself.
  
  I have a page that contains a dynamic region in it. I will make reference to the page container as the parent and child of the region. The parent and child have all two objects different trades related to them, although they are part of the same module of the application. The parent page contains a submit button that needs to validate the data entered by the user in the parent and child pages. This action should not proceed if there are validation errors in the parent or child. Validation should trigger on the page parent without any work on me because of ADF's handling of the situation. The page of the child is informed of the action to submit via contextual events. I currently where this event can trigger the action of "committing" successfully, but I have no idea how to do to make sure that they cause so a validation control.
  
  Overall throughput I think happen in the final version is probably:
  1: introduce the button.
  2: validation of the parent page is checked (if success, go ahead)
  3: contextual event
  4: contextual event is received by the child.
  5: the child raises his own validation (if success, go ahead, otherwise stop)
  6: the child triggers a validation action
  7: the child sends a contextual response event (signaling he succeeded)
  8: the parent receives the contextual response event
  9: the parent performs an action to 'commit '.
  
  
  I don't know how to do step 5 to happen, and I don't know if steps 7 through 9 are needed again (I have not tested to see if the origin of the validation in the parent or the child will eventually cause all objects changed entity to commit). Any help would be greatly appreciated.
  
  Thank you

  Hello

  You can access a command button on the page fragment and its action event queue. For that access you a managed bean (range backingBean) that contains a handler for the command button and the event queue (so will perform validation as if the user has clicked on it. The command button can also be hidden on the fragment.

  Have a look here for how you can integrate the bean managed as the contextual event handler
