• using the value of the point of application in javascript

  Hi all
  
  Apex 3.1
  
  I have a javascript that calls an application process, please see below. In the application process, I have create/modify the value of an element of the application logic. Later in the javascript, I need to define a page element to the value of the application element that has been created in the application process. All of the alerts that I post for the javascript display this value as empty, even though a similar HTP.prn in the process of the application displays the value! Once the completed script the correct value of the issue of enforcement is in session state. Can someone explain this problem of sync for me? Why can't I get the value of an element of application in javascript code when the application process is called by the javascript code?
  
  Is there a simple solution for me to get this value?
  

  <script>
  function f_ValidateLinkLine(pThis) {
      
     // The row in the table
     var vRow = pThis.id.substr(pThis.id.indexOf('_')+1);
     
     // is Link Line really a number?  
     if ( isNaN(html_GetElement('f20_'+vRow).value)) {
          if (html_GetElement('f20_'+vRow).value.length > 0) {
          alert('Link Line is an invalid number - '+html_GetElement('f20_'+vRow).value);
          html_GetElement('f20_'+vRow).value = '';
          }
     } else {  
         if ( ! isNaN( parseFloat(html_GetElement('f20_'+vRow).value) ) ) {
  
     var link_line = parseInt(html_GetElement('f20_'+vRow).value);
  
     if (html_GetElement('f20_'+vRow).value.length > 0) {
  
        var get = new htmldb_Get(null,&APP_ID.,'APPLICATION_PROCESS=ValidateLinkLine',0);
        get.add('F101_LINK_LINE',html_GetElement('f20_'+vRow).value);
        get.add('F101_INVENTORY_ITEM_ID',html_GetElement('inventory_item_id_'+Number(link_line)).value);
        get.add('F101_QUOTE_LINE_LINK_ID',html_GetElement('f01_'+spacer+link_line).value);
        get.add('F101_QUOTE_LINE_ID',html_GetElement('f01_'+vRow).value);
        get.add('F101_QUOTE_NUMBER',html_GetElement('f19_'+vRow).value);
  
        gReturn = get.get();
  
  
     // The application process can sometimes change the value of F101_QUOTE_LINE_ID
    //  and I need to set f37 to this value when this happens
  
      html_GetElement('f37_'+vRow).value =('&F101_QUOTE_LINE_ID.');  //< -- This does not work, the applicaiton item is blank!
   
        if (gReturn) { 
         alert(gReturn);
        }
   
        if(gReturn) { 
         html_GetElement('f20_'+vRow).value = '';
         html_GetElement('f37_'+vRow).value = '';
        }
  
     }  //End Check Length
  
    } else {
  
    html_GetElement('f37_'+vRow).value = '';
  
    } // is Link Line a number?    
   
   } // End If   
  
  } // End ValidateLinkLine

  Hello

  When you use the point of application in JavaScript, as you do, string &. F101_QUOTE_LINE_ID is replaced by the value of the session state.
  Changes to this value of the item when you call process On Demand do not affect the page.

  Lets take for example,
  You app element value of F101_QUOTE_LINE_ID is for example XX in session state.
  You run the page and view the source of the page that looks like this

  html_GetElement('f37_'+vRow).value =('XX');
  

  Like you have a value hard to JavaScript code.

  Nothing can change this, unless you refresh the page.

  You need return the value of the process On Demand.
  To set the value of code might look like so

  html_GetElement('f37_'+vRow).value = gReturn;
  

  Kind regards

• The value of the point of Application via Javascript

  How do you define the value of an element of application using javascript?

  Hello

  I have not tested, but I think $s not work for point of application. He finds only the page elements.
  You can test

  $s(pNd, pValue)
  
  Given a DOM node or string ID (pNd), this function sets the Application Express item value taking into account what type of item it is. The pDisplayValue is optional. If used for a page item of type "Popup LOV" where the attribute "Input Field" = "Not Enterable, Show Display Value and Store Return Value". It will be used to set the "Input Field". The value of pValue will be stored in the hidden return field.
  
  Parameters
  
  pNd (DOM Node | string ID)
  pValue  (String | Array)
  pDisplayValue(String)

  Hi friends,

  How can I access creator of overlay controls. as a slideshow, image sequence.

  

  Thank you.

  We exposed not access to controls via the interfaces of scripts creator overlay. All the answers that you will not see elsewhere use new mechanisms that we do not support sort.

  That said, I'm certainly interested in exhibiting a supported way to do. Could you share your scenario? If you don't want to post in this thread, send me a private message. Thank you!

• How to set the value of the point of application using pl/sql in the application process

  Hi guys,.

  I want a global variable (application point) whose value will be set to start when a user logs on to the application. The value will be retrieved from the database by using a sql query. I don't exactly know the syntax to set the value of the point of application in the application process. Also, I want to know what type of enforcement process should I use to set the value of the point of application, when a user starts a session. The value of the point of application varies from one user to the user.

  Help, please.

  I use apex 4.2

  Kind regards

  Waqas

  You can use the application element as a link with his name. That is to say. your point of application is named G_MY_APPLICATION_ITEM, then you can / set of access using: G_MY_APPLICATION_ITEM.

  For example

  BEGIN

  -assign as a variable

  : G_MY_APPLICATION_ITEM: = 'LARRY ';

  --

  -use in a SQL statement

  SELECT WHATEVER_COLUMN

  IN: G_MY_APPLICATION_ITEM

  FROM MY_TABLE

  WHERE USERNAME =: APP_USER

  ;

  END;

• Dynamic action to set the value of the point of Application

  Hello
  I want to display a form button that sets a value of the point of Application. Can someone please help and guide how to proceed?
  
  The requirement is, the user will receive a report, they can change a record and a button will allow him to SET the record for the session. When it accesses a different page within the application, they will see that the data relevant to the record that is DEFINED.
  
  Thanks in advance
  Aali

  Hi, Estelle,.

  You can use the dynamic action 'Code from PL/SQL Execute' to fix your application. For example, your code might look like

  begin
      :G_DISPLAY_MODE := :P1_DISPLAY_MODE;
  end;
  

  Page items to submit: P1_DISPLAY_MODE

  P1_DISPLAY_MODE would be the element on your current page where you select the desired value.

  Hope that you give something to play with.

• How to access the tab 'Save all' when I close several jpeg files that have been adjusted with the "color adjust tool? He is currently making me close and save one at a time. Thanks for any help :)

  How to access the tab 'Save all' when I close several jpeg files that have been adjusted with the "color adjust tool? He is currently making me close and save one at a time.  I've just upgraded to El Capitan.  Thanks for any help :)

  I assume that you use the application overview.

  I can't find an answer to back up everything, but a workaround could be while the file menu options are visible, press the option key

  and the point of the window will become close, if you click on that dialogue will ask you if you want to restore the changes or save

  pressing Save will close the image with the changes and then move to the next image and so on.

• How to access the sbRIO DIO pin

  How to access the pin the sbRIO DIO.

  Your FPGA code is more complex that it should be.  Something like this will do what you want.

  

  Now your RT code... You are simply flashing the fater LED that you can see.  While some expected between your output setting.  I would also use a shift register to store the current value and then just reverse.  In this way, that you have only 1 entry per loop.

  

• Multiple column trees: how to access the data in columns? There is a bug?

  Hello

  I have a strange problem. I use tree column multi like this:

  

  In this case, I have the tree column and two other custom columns.

  Now, how to access the data in the SECOND column?

  We can write all the data in a row thanks the EditElementTree:AddElement:ChildText, because it is an array of strings.

  However, when I want to read the data, I use ActiveCelltring, meaning that a SINGLE string and not a string table oO (so I only have the value of the first column and never others.

• How to access the attributes of VO through binding...

  I have a lookup table that has 2 columns namely encode and attrib.

  I created a ViewObject with SQL like:

  SELECT THE CODE, REFER TO THE STUDY_TYPE_CODES

  And he stated in an Application Module.

  Now I want to post it to the end-user as part of a selection
  that should show REFER to but returns the value CODE.

  I want to iterate the elements and generating the choices myself.
  So I tried this on my page:

  < af:selectOneChoice label = "Test" required = "true" >

  < af:forEach elements = "#{bindings." Var StudyTypeCodesVVO1.allRowsInRange}"="row">

  "< af:selectItem value =" #{row.code} "label =" #{row.describ} "id ="si3"/ >

  < / af:forEach >

  < / af:selectOneChoice >

  It gives an error. Looks like how I use
  "#{row.code}" or "#{row.describ} ' is false.  If I ' # {line} "then
  It's OK, and I could see that the line is a

  ViewRow [oracle.job.Key []]

• How to access the BPM 11 g load useful or process varibles in the workflow of ADF

  I'm trying to view/edit the data in a user interface that is linked to a database by using a foreign key, requestId. The foreign key comes from a BPM process where it is spent in the workflow, a human task. The foreign key comes process variables or values of payload. I know that I can simply load the payload in BPM with the data in the tables, but I'm looking for a better solution use the ADF business components to view and edit data directly in the user interface.
  
  The BPM process uses a web service to start the process. Web services takes a primary key as a parameter to reference a column in the database table. The data is pre-filled with content and a primary key reference. The first activity is an activity of the user. I want the workflow behind the user activity to accept this primary key and use to locate the line in the database, so related views of the database delimited ADF business components can work to present the data in the user interface.
  
  I tried two approaches to the problem. The first uses the setCurrentRowWithKeyValue operation. The other changes the SQL where clause, used by the ADFbc iterator only returns one row for the given requestId. Both of these approaches fail to work because I don't know how to access the load BPM or variable data entering the workflow. Here is the piece of code that I used to try to define the row using the value of setCurrentRowWithKey:
  
  public String setRequestId() {}
  
  FacesContext context = FacesContext.getCurrentInstance ();
  Object requestObj = context.getApplication () .evaluateExpressionGet)
  context, "#{bindings."(, Number.class) RequestId.inputValue "};
  If (requestObj is nothing)
  Returns a null value.
  RequestId number;
  requestId = (number) requestObj;
  
  ITR DCIteratorBinding = (DCIteratorBinding)
  
  getBindings () .get ("PatfRequestHdrView1");
  
  itr.setCurrentRowWithKeyValue (requestId.toString ());
  
  Returns a null value.
  
  I didn't get very far with the second approach, change SQL where clause, because I do not know Groovy. I think I need something like:
  
  adf.object.viewObj.RequestId. but it is not a viewObject associated with BPM data, so I don't know that this particular expression will not work.
  
  Any help you can give me is greatly appreciated.
  
  Kind regards
  Mark

  Try this code in your method:

  FacesContext context = FacesContext.getCurrentInstance ();
  String ctx = (String) context.getApplication () .evaluateExpressionGet (context, "#{pageFlowScope.bpmWorklistContext}", String.class);
  String tskId = (String) context.getApplication () .evaluateExpressionGet (context, "#{pageFlowScope.bpmWorklistTaskId}", String.class);
  IWorkflowServiceClient workflowSvcClient = WorkflowService.getWorkflowServiceClient ();
  ITaskQueryService wfQueryService = workflowSvcClient.getTaskQueryService ();
  IWorkflowContext wfContext = wfQueryService.getWorkflowContext (ctx);
  Task myTask = wfQueryService.getTaskDetailsById (wfContext, tskId);
  XMLElement xmlPayload = (XMLElement) myTask.getPayloadAsElement ();
  get the payload as a string simple, useful for debugging
  java.io.StringWriter writer = new java.io.StringWriter ();
  xmlPayload.print (writer);
  String payloadAsString = writer.toString ();
  extract payload values: use methods in Oracle XDK

• How to find the point of intersection of the two geometry?

  Hello
  Could someone give some suggestions on how to find the point of intersection of the two geometry?
  I need just point. (x, y, z)
  Thank you

  Can you post the full result of geometry returned?

  What you should have as a result:

  MDSYS. SDO_GEOMETRY (2001, 1, NULL, MDSYS.) SDO_ELEM_INFO_ARRAY (1,1,1), MDSYS. SDO_ORDINATE_ARRAY (2.0,2.0))

  Notice the sdo_intersection will use only the sdo_ordinate_array, even if the result is a point! (with the SDO_POINT is NULL.)

  where do you find these x, y, z values of?

  On your other question:

  -using the operator space sdo_relate (with mask = ANYINTERACT) will return in pairs, the result of the intersection of each anyinteracting polygon, line combination.

  -of course, these results will vary from point, multipoint, line or multiline even depending on how the interaction takes place.

  -try to explain a bit more what do you mean 'I want only points to return' of nit.
