• The default value for the elements of the page get ready when the session is disabled

  Hello
  
  I am facing this problem, do not know how to solve this problem. Basically, the default value 'elements' on the page don't prepare you when the session is disabled and I visit the page for the first time. So when I check the session for the first time, all page elements are null. But when I revisit the page, page elements sometimes gets.
  
  Don't know what I'm missing here... Someone has encountered this problem before?
  
  Thanks in advance! Kindly let me know if you need more clarification.

  Is there a way that the page element can be defined at the time the page is loaded for the first time?

  Yes. Create a "Page Rendering" PL/SQL process. That it is very early in the page rendering (i.e. "on charge ‑‑ after Header"). Set the value of the element of page here:

  BEGIN
    :P10_MY_ITEM := 15;
  END;
  

• How to display the activated checkbox in selectManyListbox when the page loads.

  I need to display the box on page ready.
  
  Following code shows a checkbox with the checkbox 'All' as well.
  
  < af:selectManyListbox label = "category of FaQ.
  Binding = "#{backingBeanScope.TestBackingBean.catSelectMany} '"
  ID = "catSelMany" autoSubmit = 'true '.
  required = "true".
  valueChangeListener = "#{backingBeanScope.TestBackingBean.handleSelectedCategoryValue}" >
  < f: selectItems value = "#{backingBeanScope.TestBackingBean.product1List}" id = "catSelItems" / > "
  < / af:selectManyListbox >
  
  On the value change listener, next server, I found that the values are in the table. As the selected values are: [0, 1] like that...
  
  How can I put the value as well as on the page load, I can display a selected check box.

  In the code, I see that you have linked the selectItems list to the value property of selectManyListbox which is incorrect. List of the selectItems must be bound to the value property of f: selectItems and the value property of SelectManyListbox should point to a variable of the list with the getters and setters. If you want to show something is selected by default, you must initialize the list linked to the value property with the values you wanted to show as selected.

  Sample:

  
       
  
  
  // Declare and Initialize product1List with the values 0 and 1 if you want to display product0 and product1 as selected by default
  private List product1List = Arrays.asList(0,1);
  //Add getter and setters for product1List

• What elements of the page get included in the URL on doSubmit()?

  It's quite perplexed me.
  
  I have a page with 5 items on the page in a region in a table. All of them are hidden and protected.
  
  The page is loaded with one of these items on the page specified in the URL.
  
  If I use the button to delete one or more rows on the, or click on the button "Add new line", the page is submitted and returns with three of these five elements in the page specified in the URL.
  
  First question: why only 3 and not all 5? Why THESE three? I see no difference between one of the page elements appear in the URL submitted from that which is not.
  
  Second question: I've changed one of these page items to display conditionally. If a certain condition is not met, the field is never out of the page. However, EVEN THEN when I send the page using one of the buttons above, the field is included in the URL submitted! Should that even happen? That actually seems a safety hazard, unless there is something I am doing wrong.
  
  I can probably create a test page to apex.oracle.com if necessary. (It of now on apex.oraclecorp.com, but move it will take time because I'll have to remove some sensitive data). But I hope that it is just some easy concept to explain, I'm just not grasp.
  
  Thank you.

  Hi Keith,

  (1) check the branch. the branch defines what happened on the next page.

  (2) Yes, this is the correct behavior. condition is for rendering, but the direction is fixed.

• Components of the access to the content on the page loading

  Hello
  
  I use ADF Faces 11g.
  
  I have a chart element in a page. The page has a support bean and the graphic component is bound to a variable in backing bean.
  What I want to do is to manipulate this component before loading the page. I tried to implement beforePhase and afterPhase PagePhaseListener and access to the component of these methods, but these methods are called before that the elements on the page are initialized. So I get a null pointer exception when trying to get the component in beforePhase() or afterPhase.
  
  What should I do to access a UI component in the page on all access to the page?
  
  Thank you.

  Hi Deniz,

  Exposing how the page for support of bean and add the component you want to add in the Set accessor of the form method?

  Something like

      public void setF1(RichForm f1) {
        RichCommandButton cb1 = new RichCommandButton() ;
        cb1.setText("Button added from backing bean");
        cb1.setId("cb1");
        cb1.setVisible(true);
        f1.getChildren().add(cb1);
  
          this.f1 = f1;
  
      }

• You will return the "Select an element in the page" button right in Inspector?

  The 'select an element on the page' is to the extreme left now. Since ver.32 FF. As seen in this image:
  https://MDN.mozillademos.org/files/8315/Inspector-select-element-fx32.PNG
  Change for the worse in my opinion. You will return it right into the next version? Thank you.

  N ° it is always on the far left in the current construction of 35.0a1 of Firefox.

  All Toolbox items are on the far right, including the gear button options to define what items to display.

• Get the values of default table row when the page loads

  Hello

  I am running JDev 11.1.1.7. We have a page that contains two tables in a relationship of the master / detail of nickname. We can do a real master ADF / detail with view items related because the query for the 2nd table is complex and works best when queries with binding settings. The View object for the 2nd table has a request with 2 link params as it can get in the first table. Thus, when a line is selected in the first table we want to execute ExecuteWithParams on the object from view of the table 2. We do it in the Bean managed for the page in a method that is the selection to the first table listener. It works fine except when the page initially loads, the first line is selected by default. When the default value is selected the selection listener is not triggered.

  I've seen the suggestion of not having a line selected by default when the page loads by removing the value selectedRowKeys on the table. However, we do not want that the 1st row of the table secondary master to be selected by default and we as the table of detail to show the correct corresponding lines.

  Steve

  Steve,

  Not really sure when you say that the 2nd table is complex and may not use the master detail. If the settings link in the parent table, you can set the ViewLink accordingly and it should work, right?

  In any case, if you're after the execution of methods on the loading of the page, you will find the links below.

  If it's a working group, you can add a methodCall as activity by default and UTF, you can use phase listener (if listener server does not).

• Possible to display an icon from loading until the page load completely?

  4.2.1

  THM:2

  Hello world

  I have an application with two expensive queries that takes a while to load (on the page sent). On the page there is a selection list filter. When the user changes, the page is sent and two classic run reports based on this filter. I have a dynamic action (load which) goes off on the amendment of the list and then submits the page. However, the loading icon is visible until the moment where that page is submitted. Once the page is sent, then also the reports takes some time to display all of the records. Is there a way to display some sort of an icon of loading time of the page load completely? OR this is not possible.

  Thank you!

• Classic report that spans the page loading

  THM:2

  4.2.1

  Hi all

  I have two classic reports side by side, based on a somewhat expensive query that returns a number of lines (500) also, we have a box of research and other filters to work on this report. However, the problem is that when the page loads, since the reports run sequentially, the first report on the left side, extends all the way to the right for a few seconds before returning to the right size. I guess this happens because then the second report query (right) runs and pushes the left up. Is there a way to fix the two classic reports width such that it does not stretch on page load?

  Thank you!

  Region change and put css in the attributes of the region to set the size of the region

  style="height:300px;width:500px;"
  

  or you want scrolling of fixed size, if your report has no more. columns fit more in the size

  style="height:300px;width:500px;overflow-y:auto;"

• Initial request on the Page loading

  Hi all

  I use Jdev 11.1.2.3.  I have a page with a simple table based on a view.  I want that he executed not the query when the page loads.  Now that I've seen many comments on this question and blog of Shay spot on that too, but what I see is the following.  When I have the table on a tab of the Panel with nothing else dressed the steps previously suggested, if the value of itterator #{! adfFacesContext.initialRender} and or affecting the value #{bindings. {LocalDate.inputValue not null}, seem to work splendedly.  But when I put a collection of panels around the table the methods above do not seem to work.  What I lack or y at - it another way I can get cela no query when the page is loaded?

  Thanks in advance for any advice.

  Steve

  #{! adfFacesContext.initialRender} is not very good approach to accomplish your use case, because sometimes is not clear what exactly is 'initial render' (for example, when you have defined a workflow set as region...)

  Instead, you must call YourViewObject.executeEmptyRowSet () before you navigate to the page.

  To learn how to execute the method before loading the page, see this blog: https://blogs.oracle.com/adf/entry/an_epic_question_how_to
