• Impossible to trigger value change listener for a checkbox custom AF: table

  Hi all

  IAM using Jdev 12 c.

  I have a created a table and a list bound to the table. The values are perfectly filling. I added a checkbox as another column. All select/deselect the box, no event is triggered... Please find below the the code I used.

  JSPX code binding the table and column checkbox

  < af:table var = "row" rowBandingInterval = "0" id = "t1" binding = "#{EmployeeTableList.empTable} '"

  contentDelevery value = "#{EmployeeTableList.empList}" = "immediate" > "

  < af:column sortable = "false" headerText = "EMPID" id = "c1" >

  < af:outputText value = "#{row.empid}" id = "ot1" / > "

  < / af:column >

  < af:column sortable = "false" headerText = "EMPNAME" id = "c2" >

  < af:outputText value = "#{row.empname}" id = "ot2" / > "

  < / af:column >

  < af:column id = "c8" headerText = "Select" >

  < af:selectBooleanCheckbox label = 'Label 2' id = 'sbc2' autoSubmit = "true" value = "false".

  valueChangeListener = "#{EmployeeTableList.newlyCreatedMethod}" / >

  < / af:column >

  < / af:table >

  I tried the javascript also, but not luck at all... If you use IAM table datacontrol and adding a column of the box... value change listener is triggering perfectly.

  Please help me. Thanks in advance.

  Hi Ram,

  Thanks for the reply... I can trigger other events in the table.

  Finally, finally, I got solution... I use the scope of the request for the bean managed in my application. I changed the scope of the request to see... then is triggering events to change value perfectly.

  Thanks everyone for the help and support!

• disable the value change listener until the previous process is complete

  I use Jdeveloper 12.1.2

  I have a text field that has a value change listener. The listener calls a function that manages a number of process and queries. The function then clears the text entry field and focus the cursor in the text entry field.

  My problem is that the user will enter the text back to back quickly it causes all locked up. Is anyway to prevent the user to enter additional text before the end of the listener.

  I tried the following, but he has not always prevented the user. At the beginning of the listener:

  FacesContext facesContext = FacesContext.getCurrentInstance ();

  UIViewRoot root = facesContext.getViewRoot ();

  InputText RichInputText = (RichInputText) root.findComponent ("it4");

  inputText.setDisabled (true);

  AdfFacesContext.getCurrentInstance () .addPartialTarget (inputText);

  then at the end of the listener, I re activated the field.

  inputText.setDisabled (false);

  AdfFacesContext.getCurrentInstance () .addPartialTarget (inputText);

  Maybe this can help: http://www.jobinesh.com/2010/10/preventing-user-input-on-fusion-web.html

• 11.1.2.3 JDEV get the selected value of RichSelectOneChoice at the bean (but not in the value change listener)

  We have implemented our own listener of downloading files to export the table data in Excel. The reason for this was that we did not want certain columns to export.

  We have the collectionmodel table. All columns have been extracted from the table and for each column the value inside the component was read and written in the outputstreamwriter.

  Now the problem is, we have a few selectonechoice fell in the columns of the table read-only. For components, it exports the data that the index selected and the value selected.

  Is it possible that I can get the selectedValue of the component of type RichSelectOneChoice in the bean?

  We use Jdev pointers 11.1.2.3... Any are appreciated...

  Found the solution. Add LOV VO as iterator in a combination to page and access it as below... use index that selectonechoice.getvalue returns as well as the name of the iterator.

  BindingContainer links is BindingContext.getCurrent () .getCurrentBindingsEntry ();.
  DCIteratorBinding dciterContainer = (DCIteratorBinding) bindings.get (iteratorName);
  Ri rank = dciterContainer.getRowAtRangeIndex (index.intValue ());
  String val = (String) ri.getAttribute (attrName);

• value change event not called on the evolution of the value falling down

  
  Hello

  I have a drop down with values such as... 1-25, 26-50 and so on.

  I need to see the 1-25 as pre-selected when the page is loaded. and when we change the value in the drop down a listner valuechange is called and will service call.

  But when I again selects the default 1-25, at the time where only the value changes listner is not called.

  To show the value that pre-selected I put:-noOfRecSOC.setValue(1);

  noOfRecSOC is the drop down on the screen.

  You must not directly set the value in the UI component. Use the property value drop-down list together for years by default here. Otherwise the value change listener do not notice the change to the original value (as it is never changed).

  You can use a variable temporary pagedef for the value. check out my blog Creating Variables and attribute Bindings to Store values temporarily in the PageDef | JDev & amp; ADF Goodies to find out how to do this.

• Pass the value to the process of request through javascript

  Hey everybody,

  I am currently struggling with the call to an application process and passing a value to it through javascript. Ideally, my javascript is triggered by a dynamic action, which itself is triggered when a user changes the value of a selection list. Below is the javascript code that is relevant:

  for (k=0; k<active_array.length; k++){
        var request = new htmldb_Get(null, &APP_ID., 'APPLICATION_PROCESS=CAL_COLORS', 0);
        request.add('x01', check_array[j]);
         var ajaxResult = ajax.get();
         alert(ajaxResult);
        active_array[k].parentNode.style.backgroundColor=document.getElementById('P14_TEST_COLOR').value;}
  

  And she calls the application process is also shown below:

  declare
  v_color varchar2(20);
  begin
  select color into v_color from cal_colors where other_user = apex_application.g_x01 and user_id = :USER_ID;
  :P14_TEST_COLOR := v_color
  end;
  

  The issue seems to be that online 03 my JavaScript, especially since my array element is not spent properly in my process. In an attempt to debug this, I added the alert message, however, instead of any relevant information, the alert shows just the HTML page! I'm at a loss as to what I'm doing wrong here, so if anyone has any input, I would very much appreciate it.

  Basically, you need to rewrite in the http buffer, using htp.p:

  DECLARE
    v_color VARCHAR2(20);
  BEGIN
    SELECT color
      INTO v_color
      FROM cal_colors
     WHERE other_user = apex_application.g_x01
       AND user_id = :USER_ID;
  
    htp.p(v_color);
  EXCEPTION WHEN no_data_found THEN
    htp.p('white');
  END;
  

  You could potentially make it much more efficient also. At the present time you loop on what is probably an array of elements, so from a tabular form probably. Rather than call an ajax for each line, you can group together them and make a call.

  Example:

  JS, you can use this to create an array with values to be placed on the server:

  var lArray = [];
  $("input[name=f03]").each(function(){
  lArray.push($(this).val());
  });
  

  And you can use the apex.server.process api to call a process on demand:

  apex.server.process("MYPROCESS", {f01: lArray}, {success: function(pData){console.log(pData);}})
  

  As you can see, the table with the values is put in the table in the f01. You must use the option of success well since it will be asynchronous (htmldb_Get.get is a synchronous call).

  With respect to the CLASS code:

  DECLARE
    l_return VARCHAR2(4000);
  BEGIN
    FOR i IN 1..apex_application.g_f01.count
    LOOP
      l_return := l_return || '"VALUE' || i || '",';
    END LOOP;
  
    l_return := RTRIM(l_return, ',');
    IF l_return IS NOT NULL THEN
      l_return := '[' || l_return || ']';
    END IF;
  
    htp.p(l_return);
  END;
  

  It will loop through the items in the table-f01 and build a new JSON notation and write it back to the http buffer so it returns to the client. It will look like this:

  ["VALUE1", "VALUE2", "VALUE3", "VALUE4", "VALUE5", "VALUE6", "VALUE7", "VALUE8", "VALUE9", "VALUE10"]
  

  I say this because when users use your application, you do not want such a quantity of calls. A single call by treatment action would save a lot of resources. You may have to loop twice on your items to apply your backgroundcolor, but I don't voluntarily not too mention jQuery since you is perhaps not familiar with it and get scared by him.

• Pass the value of the variable during execution

  Hello
  
  I have a package with a set of interfaces and three other variables.
  
  I want to pass the value of the variable at runtime, based on the value passed I want to decide which interface to run then. How can I do this? I got a set variable but I want to asssign the value during execution.
  
  Any help is greatly appreciated.
  
  
  Thank you
  San

  You have many options to achieve this goal.

  1. keep the run settings in the database, extract the Variables in a time of refreshment and use these variables in your Interfaces to get values of execution.

  2. change the value to the variables on the outside. You can declare a variable in a package as a step of the statement, and then use the variable in your interface in a successive step in your package. Then, create a scenario of your package and creating the scenario, it will prompt you to include the variables that you want to include as a startup parameter. Choose the one (s) concerned. Citing this scenario using Java or an OdiStartScen command or by using Webservices ODI externally, you can provide values of the runtime as a result.

  I hope this helps.

• Passing the value of the SQL query select list

  Hello

  In my application users have in their homepage to a region which has two simple things, a part of LIST SLECT lov function and a BUTTON

  There is also another page which has a normal life to report which shows the employees.

  
  

  Homepage the user can select certain number of Department in its 'SLECT-LIST' and click 'open '.

  
  

  For example: If the user has selected a DEP_NUM_5 and click on the BUTTON it will be redirected to the page of a report and gets only showed the employees belonging to the Department 5.

  
  

  The report page contains a simple SQL query, and I understand that somehow I must pass the value in the SELECT LIST, where I now have the '?

  
  

  How can I do this, where should I start?

  Of course I would really appreciate an example of code, if anyone has time to do a.

  
  select "EMP_ID", 
  "EMP_FORNAME",
  "EMP_SURNAME",
  "DEP_NUMBER"
  from EMP E
  where E.DEP_NUMBER = ????????
  
  

  Hi Sozua,

  1. create an item hidden on the page where you have the report.

  I say P2_DEPT_NO

  2 assign to that in your sql query

  select "EMP_ID",
      "EMP_FORNAME",
      "EMP_SURNAME",
      "DEP_NUMBER"
      from EMP E
      where E.DEP_NUMBER = :P2_DEPT_NO
  

  below the area source ther is also an option

  Elements of page to submit-> put this element in this.

  for example;

  Page to submit items: P2_DEPT_NO

  3. change your button

  Action: Redirecting to page of this application

  Page: 2 / / assuming that page 2 is the report page

  Place these items: P2_DEPT_NO

  with these values: & P1_SELECT_LIST.  assuming that selection list is on page 1

  Hope this helps you,

  Kind regards

  Dear friends,

  I have a requirement like when I select a selection list value I should pass this value to sql query where clause without submitting the page

  ex I have a select like: P1_Dept guess I selects the value 10 in this

  then I have a query select * from emp where deptno =: P1_Dept.

  DB. ORACLE 11G

  Suppose we have the selection list with the name P1_DEPT and query for report

  select * from emp where deptno = :P1_DEPT
  

  We create dynamic Action on the evolution of the P1_DEPT point. We will need two real actions:

  1-> set value action

  Set the Type - > body of the PL/SQL function

  The function of body - > return 1;

  Page item to submit-> P1_DEPT

  Change to delete-> Yes event

  Selecttion Type-> trigger element

  2. action-> Refresh

  Selecttion Type-> region

  Region-> your region of report

• Pass the value modal page using static URLS

  Hi guys,.

  I have a simple page with three boxes.

  When one of the check boxes is selected, I want to draw a new page which I use as a modal page (SkillBuilders Modal plug to help).  I need to pass a value of a checkbox (P1_WTD_OPT_OUT) in the new modal page.

  I have the following in the static URL

  f? p = & APP_ID.:2: & APP_SESSION.:2:P2_WTD_ID, P2_WTD_OPT_OUT: & P1_WTD_ID, & P1_WTD_OPT_OUT. :

  where I'm moving the value of P2_WTD_OPT_OUT to P1_WTD_OPT_OUT.

  As I don't submit anything when the check box that calls the modal page is checked, how I would pass the value in the modal page?

  At the moment, if P1_WTD_OPT_OUT is enabled or not, P2_WTD_OPT_OUT is always null when modal page.

  I use apex v4.0

  Any help would be great,

  Thank you

  Here is what goes wrong:

  -page is first rendered, P8_WDT_OPT_OUT is NULL

  -the static url for the modal lov is generated. Given that the item is NULL value in the url for the P9_WDT_OPT_OUT point shall be void in this url

  -l' change event fires. The P8_WDT value is stored in session state

  -the modal opens and navigates to the static url

  End result is that the P9 indeed will be null.

  The solution to this is to not not to set the value of the item through the URL, because it will simply not work. But given that the element of P8 is located in session state, you can use the value of it to the default value of the element on P9.

  On page 8, I changed the dynamic action to not set the value of the element in the URL, and on page 9 I changed the default value of the element.
