Spend Parm in the region of contextual event - jdev 11.1.2.3
Hello:I have a general question on the passage with the events pop-up settings...
Here is my configuration: TaskFlowA PageA, TaskFlowB the PageB (pages are fragments dropped like static regions)
I need to pass a parameter oracle.jbo.domain.number to relay to PageB and I do not understand how to do this.
I don't want to use the page bounding PageB and connections to relay this at all, just. (region to region only)
Anyone know the appropriate measures?
I tried to use the contextual PageA event payload, so I have the data I need from it. But how PageB receives these data?
I think that through the method the event binding subscribed or what?
Then, click on a button PageA should define the payload, I understand that.
But how PageB receives the payload? What is a simple way to achieve this?
Can anyone point a simple article that explains this use case?
Thanks for the help.

Hello
payload is the way to go. If you implement the callback model has explained in this document http://www.oracle.com/technetwork/developer-tools/adf/learnmore/regionpayloadcallbackpattern-1865094.pdf, access the value of the payload will become a piece of cake that model works with a managed bean reference set to the receiver limited workflow

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:
and in the code of bean:<af:commandToolbarButton ... actionListener="#{BBean.commandUndoRedo}"/>
and in taskFlow page def: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 when I try to find this event in any other workflow in pageDef - links - ContextualEvents - subscribers-<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>
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(); } You can check

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
PaulHello
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.

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.You define a bean holding your values and pass an instance of the bean as a payload...

How to UN-restrict the movement of the regions to take
The use of Logic Pro 10.2.3, I want to spend an excerpt from a plug to another track (which is not in the same folder to take). This is the procedure I use:
- Make sure the quick slide is off
- Cuts in the region to isolate the part I want to spend
- Drag the region upwards or downwards to the other lane.
This works, because the logic is binding the region so that I can spend only it other ways to take in the same take folder.
Copy and paste also don't work. When I select the region and press Cmd + X, it will appear a notification saying "Command is not available because there is no selected event."
Then, how should I be trying to accomplish this?
It is possible, but not with copy - paste. It takes a little knowledge that is actually. Here it goes:
- When you save a passage while cycling with the option 'Take the folder' selected, logic creates an audio file (record). You see that the regions themselves are just axe-upper regions of this simple Audio file. Watch the project tree, and you'll see what I mean.
- Look at my screenshot with two folders take on two different tracks. Audio the project browser shows two audio files with the individual region
- Suppose that you want to place the last region to take (that I wrote). If I click on it, I'll see what region located in the Audio project (marked on the right) tree
- To move that take to another track and take the folder, you select this folder take (in my screenshot synth) and place the playhead in the mounting position where you want to have its starting position (see arrow).
- Now right click on this area in the project Navigator to open the context Menu. The first command is "Add track" and it's what he does. He takes this region (do you) and adds it to the railway in the region highlight starting at the position of the read head
- In the following screenshot, you can see the result, take it in the folder to the Piano track is now copied to the folder to the Synth track
- "Caution 1: these are clones of the region", which means, in changing a (i.e. trim) will change the other too. TO avoid this, you can copy and paste the region in the first project Navigator before the command "add to the track.
- "Attention 2: destination folder take must be long enough to"accommodate"new take" (adjust to the right) or elsewhere, the region will be places like a region independent and not end up in the folder to.
This all sounds really complicated, but it's not. It's actually quite 'logic' and once you do it yourself and get the hang of it, it is actually quite simple and fast. Even if a procedure to copy - paste would be good to have.
Hope that helps

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)

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 youHello
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

11g: contextual events - how I fires on the change of currency?
Hello!
After posting a question here: 11g: bounded task flows, need help and advice!
I read the article on http://technology.amis.nl/blog/3365/adf-11g-how-events-in-one-region-cause-other-regions-to-refresh because I need to refresh region B when the user selects in the region A.
Now, the comments in this article suggest that contextual events are the mechanism built for that use case. So I tried that first. Online help suggests that this is what I need.
I have read online help and created an event and defined a producer and consumer card in the case where in the page of def. in the parent aid now shows how to raise the event when a methodAction binding is executed. But I need to raise the event when the user selects a row in the table of A region.
1. How do I do that? Where do I put the event? Aid says it is possible, but does not show how. Add a selection listener to support bean and call the event link from active methodAction from there? Or is there a better way?
2. I feel, that - when I use the event to call the ExecuteWithParams method binding consumer - just the VO of the consumer query is executed. That's great. But how to reset the stream to the original action? Just refresh the VO is not enough. I need to reset the stream to the original action (showing a view).
I read http://www.oracle.com/technology/products/jdev/tips/fnimphius/taskflow_in_popup/taskflow_in_popup.html and now I'm completely confused. Use the input parameters or events? If I use events, how to reset (refresh) the task flow?
Thank you
Sascha
Published by: Sascha Herrmann on October 19, 2008 15:33Sascha,
prices area A action B the same transaction? If so and the contents of box B is a dependency of the VO used in A so you have contextual events at all. So if I guess this A region contains a list of departments and region B the employee table (where DepartmentsVO is the parent of EmployeeVO) then do the following
-Navigate to the definition of region B region in the file pageDef
-the right mouse context menu allows to add parameters and then a parameter (for example changeIndicator)
-thread the parameter changeIndicator to the current line of DepartmentsVOIter key str (it's an exposed method directly on the iterator)
-Set the region to ifNeeded binding refresh
-set a partial trigger on the regionB to point to the departmentTable for the region is updated whenever the table changes lineThe parameter that you added just does nothing except it tells the region that binds the region needs to refresh. You that he point to the key of the iterator Department line because it provides the changed value.
If regionB VO is not dependent on the DepartmentVO, then you need create a setting on the taskflow bounded, which takes the value of changeIndicator to write it in pageFlowScope.currRowKey. Then create a currentRowWithKey method that is defined as a default activity and it wire up to pageFlowScope.currRowKey

-WesWes,
in fact when I reproduce with 11.1.1.6 then change value event is created for the event popup I create for a text entry field in a table. I guess you always focus on the table when you create the popup event. Check the Lady of PageDef. If you see the event under the binding of the tree, then I'm right.

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...

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.

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.htmlYou 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();

All the world is facing this problem? Appreciate you could work around that?

in this case, you use an anonymous provider ' *' and have the event tuned receiver that the name of the action. The provider name is visible only when the producer and the receiver of events are mapped in the same or a file for PageDef parent

Get the values of the components within the region on the Parent Page
Hi all
I use Jdeveloper 11.1.1.5.
I just wanted to know that my use case can be mounted to the contextual events or should I use the #{data.pageDef.Attribute.inputValue} to get the values.
I have a stubborn taskflow 'ChildTF.xml' with the fragment to say "child.jsff". Now I dragged the ChildTF.xml the other say 'Parent.jspx' page as a region. In the child.jsff page I had entered with 20 fields of form and all 20 fields are trained since a view object so I do not have the field values related to the managed Bean and on the parent 'Parent.jspx' page, I have a button. Now when you click on the button, I need to get the values of these 20 fields on the page "child.jsff".
How can I achieve this?
Thank you
ShahIf you want to access the same data that is stored in the current line of an iterator, you must add the vo to the pagedef.
