• [JDev12.1.2, ADF] How do I order dynamic region by a menu bar?

  Hallo,

  I saw the video of this useful Shay https://blogs.Oracle.com/Shay/entry/adf_dynamic_regions_switching_just in which succession of dynamic region is managed by creating a "dynamic region link" for each defined workflow to display in the region.

  I would order the change of dynamic region by clicking on the menu to a menu bar items.

  What is the cleanest to achieve this way? Can I use the scope view bean managed which JDev make me create when I drag the first bounded task flows to create the region? I saw every link that I create is added to the partial triggers in the region...

  My page container (in the region) has its own bean support. To manage the region: could I convert the scope of this bean to 'see' and use it? Or is it a good practice creating a bean completely assigned to the management of the region?

  Thank you

• Changes to engage in all dynamic regions

  JDeveloper 11.1.1.6

  I have a main page with 6 links dynamic region, a region and the buttons Commit / Rollback.

  When I click on one of the links, a different workflow id is returned and the page fragment associated with that workflow is displayed in the region.

  Each page fragment has an af:table which is based on a VO/BC.

  When I try to validate a change in the fragment of the displayed page, nothing is saved.

  I assume this has something to do with the scopes, but I don't know where the problem may be.

  I also noticed that when I make a change (to a field in a table), click on another link and return to the first link, the change is no longer there.

  What would cause validation to not see the change within the region?

  Thank you.

  HU,

  1. What is the scope of the taskflows DC: shared or isolated?

  2. do the validation button has immediate = false set?

  3. where is the commit treated in the region?

  4. What is the parameters of the taskflow?

  5. make sure a validation before moving to an another taskflow?

• Dynamic region of the ADF

  JDeveloper Studio Edition Version 12.1.2.0.0

  We have a Forms application we're calling an ADF application from. The application of the ADF is simple. A page with a dynamic region. The forms application will use a setting of url for the application of the adf to decide which region to show. Can someone explain how best to 1) capture the setting and 2) invoking the correct region. Should I put in place some - type listener of phase on the page or is there a better way?

  Thank you

  Neal

  You can add the page parameter to view activity.

  Select your view activity diagram adfc-config and in the section 'Page Settings' add the new parameter.

  "Of value" set something like: #{param.yourUrlParamName}

  As value 'to' set something like: #{viewScope.targetVariable}

  Then, in the dynamic region bean change getDynamicTaskFlowId() method, for example:

  public TaskFlowId getDynamicTaskFlowId() {
  String target = (String)ADFContext.getCurrent().getViewScope().get("targetVariable");
  if("tf1".equals(target)){
  return TaskFlowId.parse(taskFlow1Id);
  }else{
  return TaskFlowId.parse(taskFlow2Id);
  }
  }

• Dynamic region on the change from the drop-down list of values

  Hi Experts,

  Using the concept of dynamic region, I tried to use buttons as I have 4 buttons and clicking on each button, I am loading the particular taskflow. I used setPropertyListener and type = action to achieve this.

  I have a similar requirement, but I need to use the drop down list here...

  < af:selectOneChoice value = "#{mybean.value}" >

  < f: selectItem itemLabel = "First" Valeurelement = "FirstValue" / > "

  < f: selectItem itemLabel = "Second" Valeurelement = "SecondValue" / > "

  < f: selectItem itemLabel = "Third" Valeurelement = "ThirdValue" / > "

  < f: selectItem itemLabel = "fourth" Valeurelement = "FourthValue" / > "

  < / af:selectOneChoice >

  How can I dynamically load a region on the value selected by the user on top of the data. On the change of the value in the drop-down list, I need to load this particular dynamic region

  JDeveloper version 12.1.3

  Thanks in advance.

  You use a listener to change value of the duo down and detect the region according to the new value of the duo down.

• [ADF, JDev12.1.3] Why dynamic region is not spend if I re - call the currently displayed workflow?

  Hallo,

  I have a page with a dynamic region that is managed by a range backingBean bean.

  Functions "startBtf...". "are called when a menu item is clicked.

  The workflow as BTF3 is called by two different functions and each function passes a different value (used by a component of router) to the workflow through the hash table.

  The problem is that startBtf3_Search is called after the startBtf3_Create (and vice versa) the dynamic region is not updated.

  How can I solve this problem?

  Thank you

  The problem is that startBtf3_Search is called after the startBtf3_Create (and vice versa) the dynamic region is not updated.

  How can I solve this problem?

  You call the taskflow even without leaving the previous.

  To update the workflow, you have several options:

  -Give taskflow refresh 'ifNeeded' parameter and change the value of the input parameter (unfortunately, it is not applicable to your usecase because you use the parameter mapping and not point settings so setting change cannot be detected)

  -use the property RefreshCondition

  For more details, see: 23 by using task flows in regions (12 c (12.1.3))

  BTW,

  currentTaskflowId = "/WEB-INF/empty-btf.xml#empty-btf";
  

  Instead, you can change the return type for getDynamicTaskFlowId() to a string and use an empty string ("" ") instead of emptying the BTF (and in this case you don't need even of TaskFlowId.parse (part)).

• Dynamic region ADF in a popup does not load

  Hi Experts,

  Version 11.1.1.5 JDEV

  I have a page that contains a table, and each row has a command link on one of the columns.

  When I click on the link to order an action listener is called who decides the TF DYNAMICS that must be loaded in a pop-.

  Pop has up to a region Dynamics inside adf.

  The file clicked (using the command link)-based workflows are loaded in the dynamic area of the Popup.

  But, when I click on the link even for the second time or another record, that the pop-up is displayed under vacuum, the taskflow in the dynamic region isn't loaded at all. (getDynamicTaskFlowId is called and is also coated the correct TF to load)

  First, it works as expected, but its not the second time.

  I used conditional activation, but later, due to the above question, I tried to put a phrase #{true} for the property current to test if it works. There can be no.

  Please note that first time no problem. It does not work since the second click on the same record or any other document.

  Other suggestions to solve the problem above are very popular.

  Thank you

• 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.

• Question of dynamic region ADF (jdev 11.1.1.4)

  Hello
  
  I use dynamic region ADF by "Elements of Navigation order" whose action is related to a method of view range bean to set the "taskFlowId" used by "af:region".
  
  I have two 'Navigation command elements' each representing a taskflow bounded on the page (JSPX). One of the taskflow has a page fragment (such as default activity) with the only active filter af:table fell on it.
  
  Questions:
  (1) when I pass between the "Element in Navigation order" links the workflow with af:table filter is not cleared which came in her previous visit. And the table is filtered with his previously entered filter criteria. I want my table to load in the same State without applying the previous filter between the navigation.
  
  (2) even with the visible previously entered filter criteria to revisit the workflow (with af:table), research without erasing the persistent filter gives me the error "try to define a parameter name that does not intervene in the SQL: vc_temp_1.
  
  Grateful for your help!
  
  Kind regards

  Hello

  the problem is there for some time, please look at:
  {: identifier of the thread = 906415}
  {: identifier of the thread = 2157454}

  You have my oracle support? Then you can search for bug 11652292 "Readmises BOUNDED TASK FLOWS FAILED for TABLE FILTERING".

  I don't know exactly yet, but I think that you must call a method which erase the viewCriterias for your view object (the object view for your table). Your method must call oracle.jbo.server.ViewObjectImpl.clearViewCriterias (). Expose the method as a public method (so you can drag and drop of datacontrol to a view or controller) and make that the default activity in the taskflow.

• ADF 11.1.1.7: Control a dynamic region of JSP with a SelectOneChoice

  Hello user community:

  I have a need to understand How to control content within a dynamic on a JSP page region.  In the JSP page content within the dynamic region is determined by a selectOneChoice drop-down list presented to users...  I have spent hours of research and cannot identify the exact procedure for this process.   Please point me in the right direction. I look forward to any input provided.

  Here is my scenario:

  1. users will select a TransactionType in a drop-down list.
  2. According to the selection selectOneChoice the loading of a page of .jsff within the dynamic region.

  Details of the background:

  • I have a dashboard for the details of the Transaction.  This is the JSP page.
  • I have 18 Transaction_Detail fragments of page based on your that take advantage of bind variables & discovers the criteria.  Here are the pages JSFF '.

  
  

  
  

  I want the JSP page to control what JSFF page is loaded in the menu-driven selection of users drop-down.  I found a simplistic example of this ability in blog of Zeeshan Baig.  However, the logic command what JSFF page is loaded if... otherwise based, and using a workflow IDs.  I can use the flow ID of the task, but I only need 1 page JSFF responsible.

  
  

  Thank you very much!

  What you describe is a simple switch of dynamic regions. Watch the video of Shay https://www.youtube.com/watch?v=gNipIBn5Zv0

  Instead use the links to the selected region, you put the id of the workflow in a list that you put on a LOV. When you select a new value LOV the region moves.

  Hello
  
  I have 2 separate workflow in my application. 'Search-user-flow' & 'create-user-flow. I got to view these feeds in my main application (home) as a dynamic region with 2 dynamic links.
  
  My page main split into two panels where I suppose to display dynamic links on the left side and the workflow right. Want to display the default search feeds loading the home page, and when I click on the link for the user to create, create flow must be exposed to the right side. Please help me how to do the same. I was halfway through the path, but not totally.
  
  Here's what I've done so far.
  
  Step 1) creation research-user-flow (this stream were only page fragments not pages)
  Step 2) created create-user-flow (this stream were only page fragments not pages)
  Step 3) slide / move the search-user-flow in right panel of the main page as dynamic and created new "searchFlow" managed bean and the same card.
  -(After this stage, the main research stream fragment appears in my main page)
  -(Managed bean created taskID entry and the method)
  
  Step 4) slide / move the create-user-flow to the left side panel as dynamic link.
  Step 5) slide / move in the research-user-flow for left side panel as dynamic link.
  
  During the loading of my main page, I could see 2 dynamic links in the Panel left side and 1 flow to the right side panel. Now when I click on the Create User link, it's pass the stream and display the stream of the 2nd on the right. So far so good. Now, if I hit any link here after an error. Please help me how to solve this problem and make the works of dynamic region. It is really urgent and fight with past 4 days...

• 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

• How to assign components page parent of a page fragment in a dynamic region

  Hi, I am using JDeveloper 12.1.3. I have a single page request that contains a sidebar (with separator) on the left and a dynamic region on the right. One of the fragments of the page that appears in this dynamic region has a task flow that calls another fragment of page. What I do when this event occurs, it is to dynamically hide (or at least close) the left side panel. I created a bean of support that includes a method to do so. This method works very well when I call it from a test button on the parent page. But I can't understand how effectively call it a method in my stubborn workflow (page fragment). I created the method and incorporated it in the workflow. I refer to the method in the bean support. No errors are generated when I perform the navigation. I have debugging instructions that indicate support bean method is called. But the screen will not reflect the changes on the side panel. I tried to use a parent action in my stubborn workflow (and tried to have this action relative to call the method), but that did not help. I thank you very much for any assistance, you can provide.

  The problem is that you can reach the panelSplitter of off the page on which it is located. If you use a methodcall activity that you call with a parent action you get a new instance of the separator, but not then, you try to change.

  What you can try to bind the separator to a property of bean a bean view extended who resides in the workflow of the parent page. Then you pass this bean as a parameter to the flow of the task of the fragment and call the method within the bean. It of called bean reference and is listed in this article by Frank Oracle ADF May / June 2013. Make sure that you use a component for the bean property reference. On second thought, you might not even to bind the separator to the bean as you can look it up in the page directly using findComponent().
