• To access the page defined by a dynamic action item

  I have a page element that is defined by a dynamic action. However, if I try to access this page anywhere else on the page element, it is null. Y at - it a specific method to dynamically reference the value of page elements, other than the usual & p2_page_item. reference. TIA.

  Hello!

  Where do you reference point? In another DA, process page?

  & NOM_ELEMENT. the syntax is only for the static text and it will be avoided in SQL and PL/SQL. It will get only value when the page is loaded.

  If you are referencing the element DA or JS, you can get its value with the function $v (for example $v('ITEM_NAME'). If you reference the process item, you can get its value with the standard bind variables syntax (: nom_element) or with the function v (for example v('ITEM_NAME'). If this process is inside the dynamic action, value of the item must be saved before session state.

• BUG? Presentation of elements via Dynamic Action in Internet Explorer generates "null."

  I first noticed this using the newly improved apex.oracle.com. When I have dynamic action that must send the values of page element and the value is null / empty, the call to post/ajax result includes the literal 'null' as the value for this parameter.
  
  for example
  p_flow_id = 65928 & p_flow_step_id = 2110 p_instance = 574862348021401 & p_request = FLOW_PPR_OUTPUT_R1858426911545391_reset_R_1858426911545391 & p_arg_names = P2110_VENDOR1 & p_arg_names = P2110_VENDOR2 & p_arg_values = 3754 & p_arg_values = null
  
  This only happens in Internet Explorer. I use IE9, but it seems to work that way, if I put it in IE8 mode as well.
  
  I returned and tested in the Apex 4.1.1.00.23 and I got the same result.

  Hi Greg,.

  Thanks again for the follow-up. You are right, it is the "Set Value" operation that causes the problem when it is called with a null value. In fact, it's a bug of IE underlaying.

  See http://stackoverflow.com/questions/5387038/null-values-shown-in-form-fields-in-ie and also http://bugs.jquery.com/ticket/5163 strengthening jQuery

  I will file a bug to use jQuery.val () workarounds to the problem.

  Thank you

• Oracle apex dynamic action set value action does not

  Hello
  
  I have two questions, that I am trying to solve. This is the scenario:
  
  (i) 4.0 on oracle 10 g oracle apex
  (II) created a form with the following page:
  -P526_SES_DET_ID
  -P526_VESSEL_ID (selection list)
  -P526_JOB_DATE (date picker)
  -P526_DAY_TYPE (list of selection with values DAY ORDINARY (if P526_JOB_DATE is a day from MONDAY to FRIDAY),)
  SATURDAY (if P526_JOB_DATE is SATURDAY) and SUNDAY/PUB. HOLIDAY (if JOB_DATE is SUNDAY)
  -P526_LABOUR_TYPE (selection list)
  -P526_SHIFT (selection list)
  -P526_NO_OF_LABOUR
  -P526_RATE
  -P526_SES_TOTAL
  
  (1) I created a dynamic action of the value set on the P526_JOB_DATE page element to set the value of P526_DAY_TYPE to one of the three values above depending on the day
  P526_JOB_DATE falls. Parameters are the following:
  
  -Action: Value set
  -Set type: SQL statement
  -SQL statement:
  Select case when (to_char (to_date(:P526_JOB_DATE,'DD-MM-YYYY'), 'DAY')
  like ' % MONDAY % ") then" DAY ORDINARY. "
  When (to_char (to_date(:P526_JOB_DATE,'DD-MM-YYYY'), 'DAY')
  like ' % TUESDAY % ") then" DAY ORDINARY. "
  When (to_char (to_date(:P526_JOB_DATE,'DD-MM-YYYY'), 'DAY')
  like ' % WEDNESDAY % ") then" DAY ORDINARY. "
  When (to_char (to_date(:P526_JOB_DATE,'DD-MM-YYYY'), 'DAY')
  like ' % THURSDAY % ") then" DAY ORDINARY. "
  When (to_char (to_date(:P526_JOB_DATE,'DD-MM-YYYY'), 'DAY')
  like ' % FRIDAY % ') then ' DAY ORDINARY. "
  When (to_char (to_date(:P526_JOB_DATE,'DD-MM-YYYY'), 'DAY')
  like ' % SATURDAY % ") then 'SATURDAY '.
  When (to_char (to_date(:P526_JOB_DATE,'DD-MM-YYYY'), 'DAY')
  like ' % SUNDAY % ") then ' SUNDAY/PUB. HOLIDAY"
  end DAY_TYPE
  of the double
  
  -Page article to submit:
  -Select the Type: Item (s)
  -Article (s): P526_DAY_TYPE
  
  The SQL statement sets the value of P526_DAY_TYPE that when I replace: P526_JOB_DATE with a date like January 11, 2010 format ' and a date is taken to
  Duration otherwise it doesn't.
  
  (2) want to be able to maintain the values of P526_VESSEL_ID, P526_JOB_DATE, P526_DAY_TYPE, P526_LABOUR_TYPE, P526_SHIFT after an insert action as default values for the next create another form operation.
  
  Like all the ideas on how to implement or to solve problems (1) and (2) would be very appreciated.

  If you want to use P526_JOB_DATE in your SQL statement add P526_JOB_DATE to the "referred to submit Page:" field.

• dynamic action - hide values if the element in the array?  syntax error (I think).

  Hello world

  I have an application page that contains a lov (gears).  If a particular device is selected, I want to hide other fields.   The value of the machine could be one of many.  I created a dynamic action using javascript... but I'm really not familiar with javascript and can't seem to make it work.   Note, there is a line below commented that compared to gear to the value of "500".  This line works and mask fields... but I need to make it work for all possible values.  Any help would be really appreciated!

• How to dynamically create action item?

  Hi, I want to dynamically create point.

  Before I want to create using qml, but does not seem possible

  http://supportforums.BlackBerry.com/T5/Cascades-development/how-to-create-action-item-of-page-dynami...

  So maybe better to use C++ to create dynamically,

  I'm already try but are still not

  So I have a custom control qml (a Navigation pane)

  name List.qml

  the structure is like this:

  NavigationPane {}

  {Page}

  objectName: myPage

  {Of container

  ....

  }

  }

  }

  How to add action item to this .qml?

  I'm already try that, but failed

  C++ :

  Engine QDeclarativeEngine;

  QDeclarativeComponent component(&engine,QUrl::fromLocalFile("List.qml"));)

  QObject * object = component.create ();

  Page * myPage = object->findChild ("Edit");  Maybe, on that note, I'm wrong implemented? -> not found?

  ActionItem * action1 = ActionItem::create () .title ("first action");

  my page-> addAction (action1, ActionBarPlacement:nBar);

  Remove the object;

  How to create this dynamic Action item?

  Help, please

  Thank you

  Hello

  QML, the object name must be included between "" marks.

  Name of the object of your Page will be:

  objectName: "myPage"
  

  You can reach any CPP QML object like this:

  This excerpt comes from YourProjectName.cpp

  // create scene document from main.qml asset
  // set parent to created document to ensure it exists for the whole
  // application lifetime
  
  QmlDocument *qml = QmlDocument::create("asset:///main.qml").parent(this);
  
      // create root object for the UI
      AbstractPane *root = qml->createRootObject();
      // set created root object as a scene
      app->setScene(root);
  
  //and here comes the findChild method
  Page* qmlPage = root->findChild("myPage");
  

  After this, you can create any object on the side of C++ QML, as your own code:

  ActionItem* action1 = ActionItem::create().title("First action");
  myPage->addAction(action1, ActionBarPlacement:nBar);
  

  Don't have no need to create a QObejct, or declarative stuff.

• APEX 4.2 limiting size of the value dynamic Action

  Hi all, I'm using ApEx 4.2.5 with 11 g BD and stumbled on this problem.

  I'm trying to set the value of a div within an HTML region. To do this, I use one set dynamic Action launched by a custom event "search" when user press enter or click OK to a search bar. I also use the PL/SQL function as set type body.

  I tested it and it works fine except if the content of the value is large enough (about 30,000 characters or more). I can't find any information about a size limitation for the return value of this type of package. I get this error code: ORA-06502 when I'm looking for a big content, and it seems that this error may occur when "you attempted to assign a value to a numeric variable, but the value is greater than the variable can handle", but I'll be back a PL/SQL CLOB variable in a div, so I don't see any kind of limitation. I think the limitation can be in the call made by apex in the background AJAX...

  I need help on this, thanks in advance.

  Hi gados12,

  gados12 wrote:

  OK, I tried something and the result is weird.

  I created a pakaged function to retrieve the right HTML content that is stored in my CLOB column (because I reached the limit of characters for PL / SQL code in dynamic action)

  So I called my function (allows to name it FNC_GET_SEARCH) my previous dynamic Action Set value. I still get the same error with large HTML content. However... it is there, it's weird.

  So that means the error is not my FNC_GET_SEARCH function, but the dynamic Action itself... So there must be some kind of limitation with this kind of dynamic action?
  Is it because the dynamic action to set the value using the package HTP in the background?

  The DA type 'Set Value' is for session state implementation and display the value of an element of page APEX value that is defined internally as VARCHAR2 (4000).

  As a result, you get the above error. Use the approach mentioned above to manage CLOB based rendering html.

  Also of your FNC_GET_SEARCH function for the display unit test error message.

• Use page LOV which has been defined by a dynamic action

  Greetings,
  
  I have a situation where I need to refer to an item hidden in a SQL statement from the list of values (for a drop-down list). It doesn't seem to work properly. Here's what I have:
  
  (1) using a dynamic action, the value of a hidden element, based on the change of select list 1.
  
  (2) select list 2 has a parent element LOV to select list 1 and the Select statement to select list 2 uses the hidden element that has been defined in the dynamic action above.
  
  I see that the dynamic action works properly. But when I change to select list 1, list 2 Select shows not all values in the LOV.
  
  I hope this makes sense. I wonder if the LOV to select list 2 does not work because the element used in the SQL statement has been defined by a dynamic action?
  
  Thanks in advance!
  
  John

  Since you use a sql query to retrieve a single value, is it necessary to have this value in a field hidden somewhere?
  Could you not change the query for you select second list to limit its results by integrating this query in lov query, for example through an is clause?

• Dynamic action fails using the null value on the list of selection change event

  I have a selection list that I created a dynamic action to which I added a value set to to clear the values of other controls on the form by assigning the value NULL.
  
  This doesn't seem to work, and I can't understand why it does not work.
  
  Event = change
  Selection type = Items
  Items = P4_MYSELECTLIST
  (no other condition for this action, I want it to reset for each change in the selection list).
  
  Fire on the Page Load = False (I only want what he reset values when I use this list of choices, not the page load).
  Set Type = static assignment
  Value = NULL
  Items = P4_ITEM1, P4_ITEM2, P4_ITEM3 (including 2 other lists of selection and control of text)
  Remove the Change = No event

  Xanas,

  If you set the values NULL and not the literal string "NULL" you must change your DA slightly. Modify your game to run JavaScript Code.

  Action = run the JavaScript Code
  Fire on the Page Load = False (I only want what he reset values when I use this list of choices, not the page load).
  Code = this.affectedElements.val ('');
  Items = P4_ITEM1, P4_ITEM2, P4_ITEM3 (including 2 other lists of selection and control of text)

  Edit:
  You can also change the real action to the following if you want to leave your DA as setpoint:

  Fire on the Page Load = False (I only want what he reset values when I use this list of choices, not the page load).
  Set Type = Expression JavaScript
  Value = "
  Items = P4_ITEM1, P4_ITEM2, P4_ITEM3 (including 2 other lists of selection and control of text)
  Remove the Change = No event

  Good luck

• How the dynamic Action to update several items based on a JavaScript Expression producing a table?

  Using APEX 4.2.

  I have the list of selection using a LOV which returns a display value and a value separated by a comma e.g. return 'reserved to items' and "66,88" or "Available items" and "90,23".

  I want that return values for example "66,88" to be assigned to two my form fields.

  I have a dynamic action that fires when the field with the changes of the list/select-LOV. I am using an action of 'Set value' and set 'Expression JavaScript' with the expression itself type value ' $v("P1_MY_SELECT_LIST").split(",") and using Type "Article (s)' selection and listing the two points that I want to set as the items in question (from the description of the JavaScript expression field it appears that a table of the results would be assigned to the changed items , in the order.

  However, the original value of the LOV return value is passed to the first of the elements concerned (complete with the comma if the original return value was of the form '10')

  If I add more REAL action of the JavaScript "alert (" HELLO "+ $v ("P1_MY_SELECT_LIST") .split (", ") [0] +" WORLD "+ $v("P1_MY_SELECT_LIST").split (", ") [1]" ") I * see two expected values.»

  Any ideas what I could do wrong?

  The action 'Set value' affects the value specified to all affected elements: a value to one or more items. To set a different value at different points, you need several actions "Set value", or simply use javascript to do it in one.

  Even if you use a javascript expression that corresponds to a table, the table is just being converted to a string again. It creates a mapping of some sort. That is why for example with '10', she also translated as such. Actually you set this value to these two elements: ' 10, ".split(",").toString () (implicit in the chain of course).

  The code makes it very obvious that it doesn't handle values, as described in the help of the element. Aid is not correct or is the implementation simply not here yet?

  Just look at the javascript for dynamic actions, images/libraries/apex/dynamic_actions.js, service da.setValue directory file:

      function _setValue( pValue ) {
          lAffectedElements$.each( function( i ) {
              // Set all affected elements to the value passed
              $s( this, pValue, null, lSuppressChangeEvent );
          });
          /* Resume execution of actions here and pass false to the callback, to indicate no
          error has occurred. */
          da.resume( lResumeCallback, false );
      }
  

  And when you use a javascript expression:

      } else if ( lSetType === "JAVASCRIPT_EXPRESSION" ) {
          _setValue( lJavaScriptExpression.call( this ));
  

  It's pretty simple. (and this is checked on apex 5. It's the same on 4.2)

• How to use PL/SQL to create dynamic action to set the value of a selection by another list?

  Hello

  I would like to know how to use PL/SQL to create dynamic action to set the value of a list of selection by another selection list.

  

  I wish can create dynamic action to manage the two above the Room select list (: P9_ROOM) and building (: P8_BUILDING).

  When you select "1074" in the bathroom, building highlights like "BRM BLD 5"

  When you select 'Area of the black box' in the room, building must assign the value "7 BLD BRM"

  When the room is Null, building should also be Null.

  I thank you,

  Alice

  I forgot to mention, for the PL/SQL Code, because you are working with items in the selection list, the return values are different from the display on your LOV values, you must instead use the return values.

  Thank you

• dynamic action sets the value of the element, but not save to DB on submit

  I'm working on a page where the value of several to show only the page elements are defined using a dynamic Action.  They are set when the user selects a value in a list of selection (and is based on the value of the selection list).  Dynamic action is triggered on a list selection change event and then runs the real action "set the value.  The selection list displays the names of sales representative.  The three fields dynamically filled are the org structure (that is, their chain management).

  For the action to set the value, I use a defined Type of SQL statement:

  Select VP, DIR, MGR

  of SALES_ORG where SSR =: P20_SSR

  In the affected elements, I have fixed Type of selection to the 'item (s)"and the value of the Item (s) for 'P20_GVP, P20_DIR, P20_MGR.

  Dynamic action works fine for the display of the page (that is, when I select a sales representative in the selection list dynamic action properly updated only display value fields three).  This page is a form in which the user submits information relating to the rep.  When the page is sent, all fields are filled in a new record of DB with the exception of three that were populated dynamically above.  These fields get the values NULL.

  When the dynamic action updates the values in the three fields is - it does not set the value of session?  Why these fields don't are not taken into account in the submit other ideas > process Page?

  I use 5 APEX with Chrome on Mac (Yosemite).

  Thanks for the note.  I didn't only display the items could not be used in this way.  I think I'll take a different approach with the design; given that the org structure is in another table that I can simply refer to that by rep when necessary rather than saving the information uploaded to the page of the form.  The reason why I have not fill the screen only the points of loading the page is because I don't know what the values should be until the user selects a sales representative in the selection list.

  I'll change the design to one of the following:

  1) change the display only items of standard text field.  NOTE: if I make the text read-only field that causes other problems when loading (I get the message "violation of protection Session state").

  OR

  2) do not include org structure in the download folder and just refer to table org Rep when necessary.

  Thank you!

• More than one Page objects of value with dynamic action parameter

  Hello

  How to set the values of the two elements of the page based on another page, article in dynamic action IE

  -variable value tr_type is set using the function get_type

  -passing the p1_code parameter

  TR_TYPE; = GET_TYPE (P1_CODE);

  If TR_TYPE = "DR" THEN

  P1_DR: = P1_AMT;

  ON THE OTHER

  P1_CR: = P1_AMT;

  END IF;

  -If I write the function get_type with Exp of PL/SQL of TYPE 'SET', it triggers the error on the use of the service.

  -If I put body of the PL/SQL TYPE of function 'SET', the page displays error unhandled expception.

  How can I achieve this using dynamic action.

  Hi, IK,.

  Can you please quote the u of changes/amendments made to the code, I am unable to find it.

  Included missing: for element names.

  --value variable tr_type is set using function get_type
  --passing p1_code parameter
  TR_TYPE:=GET_TYPE(:P1_CODE); 
  
  if TR_TYPE='DR' THEN
  :P1_DR:=:P1_AMT;
  ELSE
  :P1_CR:=:P1_AMT;
  END IF;  
  

  Here is my scenario with code.

  I have a form with 4 elements (account (P1_CODE), quantity (P1_AMT), DR (P1_DR, hidden), CR (P1_CR, hidden), I am writing a dynamic action on P1_AMT (change) of the code)

  DECLARE

  TR_TYPE char (2);

  BEGIN

  -calling a function "GET_TYPE.

  -passing the P1_CODE parameter

  TR_TYPE; = GET_TYPE (P1_CODE);

  If TR_TYPE = "DR" THEN

  P1_DR: = P1_AMT;

  ON THE OTHER

  P1_CR: = P1_AMT;

  end if;

  end;

  Again, we know not not how you want to call a dynamic action,.

  assuming that on the evolution of the account (P1_CODE), the function call GET_TYPE(:P1_CODE) to retrieve the type of transaction,

  on the basis of the transaction that you want to set the amount of specific element.

  on the change of point P1_code

  Action: execute the PL/SQL code

  Parameters

  DECLARE
  TR_TYPE  char(2);
  BEGIN
  --calling a function "GET_TYPE"
  --passing parameter P1_CODE
  TR_TYPE := GET_TYPE(:P1_CODE);
  if TR_TYPE='DR' THEN
  :P1_DR:=:P1_AMT;
  ELSE
  :P1_CR:=:P1_AMT;
  end if;
  end;
  

  page elements to present - P1_CODE, P1_AMT

  page items to return - P1_DR, P1_CR

  Check the screenshot

  

  There are other ways to set the values using dynamic action, try the above

  Kind regards
