• Dynamic action - when the 'event' and 'condition' seems to have no sense

  Step by step, I am trying to get free Javascript coding so I can rely on what natively offers the Apex. It was an interesting experience, however I have noticed certain situations sicesdonneessontdisponibles options seems to have no sense, at least to date, and you will certainly help me which can be cleared up. I tried to put one of them into words. I just created a new dynamic action that will just set the focus to an element whenever my page is loaded.

  Why my new dynamic action allows me to choose the "Page loading" event and condition "sucks"? I don't understand why this combination is available. There is probably no effect anyway, but I decided to leave the condition "without condition."

  Thanks in advance.

  It's just that there is a basic LOV status of one size for all types of events. Most of the conditions it contains is relevant to events associated with the elements. "Page Load" + "sucks" doesn't in fact make sense, but 'P4_END_DATE' + 'is null' fact. The Condition property remains visible and active so that the option "JavaScript expression" are available, as this can be used to make any event conditional.

• APEX 5. Dynamic action on the CHANGE event does not work after applying the filter on IR.

  APEX 5.

  Dynamic action for the CHANGE event does not work after applying the filter on IR.

  Event: Change, selection Type: jQuery Selector, jQuery Selector: td [header = 'abc'] entry

  Real action

  Selection type: jQuery Selector, jQuery Selector: td [header = 'abc'] entry, Action: run the Javascript Code

  Is TI WHEREAS behavior?

  I know, I can work around this problem by using the Refresh event and javascript, but I prefer DA and if possible Change event.

• PL/SQL in dynamic Action seems to return an incorrect value

  Hi all

  I am very new to the Apex and PL/SQL, so I don't know if I did something wrong here.

  I have a form with a shuttle service (P4_ITEMS) and a field display only (P4_ORDER_TOTAL). I have a dynamic action put in place with the following PL/SQL:

  declare
      tab apex_application_global.vc_arr2;
      total number := 0;
      itemPrice number;
  begin
      tab := apex_util.string_to_table (:P4_ITEMS);
      for i in 1..tab.count loop
          select PRICE into itemPrice from PRODUCTS where PRODUCT_ID = tab(i);
          total := total + itemPrice;
      end loop;
      return total;
  end;
  

  If I understand correctly, tab must contain all the elements that are in the 'selected' part of the shuttle. I try to summarize the prices of selected items and return the set. Pretty simple, right?

  Here is some info on the dynamic Action itself:

  Event: Change; Selection type: Article (s); Article (s): P4_ITEMS (the shuttle)

  The event (the PL/SQL function running) is also set to pull on the loading of the page. It is near the top not to expect results, so during the calculation, display field disappears briefly.

  Here's the number: P4_ORDER_TOTAL updates only correctly when I first load the page. I enabled debugging but I changed my Shuttle, then checked out.

  He recorded the P4_ORDER_TOTAL element. In this case, we will say it was 363.08. I added an item on the agenda and the PL/SQL is executed. The result, however, is 363.08, although he should have gone to the top. If I leave the page and then click its tab again, the order is always there, except that this time that it runs again the PL/SQL and it updates the P4_ORDER_TOTAL field to the correct value.

  Can someone explain what is happening here? I can't understand why it isn't like I intend to work.

  Feel free to ask me more questions if I'm not well explained.

  Thanks in advance!

  At the time the dynamic action is executed, the value of P4_ITEMS is not available for the PL/SQL code in session state, it takes place only in the browser. Include P4_ITEMS in elements of Page to submit property the dynamics of the action so that the changed value is updated in the State of session before the PL/SQL code is executed.

• Level elements dynamic Actions and application

  Request Express 4.1.1.00.23
  
  
  I searched everywhere for an answer on this one and I can't seem to find it. Is it possible to have a dynamic action to interact with an element of application level? If it is possible, is able to have the value field in the when a dynamic action article contains a comparison operator?
  
  An example of a real case would be:
  
  
  Element level application F111X = X
  
  Dynamic action on P4_Item is triggered and disables the field
  
  Case of falsification:
  
  Element level application F111X = Y
  
  Dynamic action on P4_Item is not triggered and the field remains active.
  
  Thank you
  Jon

  Jon,

  I'm looking for an example, and if I use your article page P4 in the box 'When', event could be the change, Type of selection would be the page element.
  P4 would be selected in the drop-down list item (s), Condition would be equal to and value would be TEST with NO quotes!

  It is difficult for me to know when the values of the quote and when not.

  What is it?

• Dynamic action for 2 fields in a table

  Greetings!
  
  I have a requirement where I need to disable/enable a field in a tabular presentation for a specific record based on the value of another field in the tabular presentation for this record.
  
  In a concern for discussion, in my particular case - if FISHCOUNT > 1, then the LENGTH must be disabled. If count < = 1, then the LENGTH must be enabled. It should disable it only records where FISHCOUNT > 1.
  
  I would do it with dynamic action and I learned through this forum (thank you!) that I can use jQuery for the event (when) the section of the dynamic action.
  
  So that the part would look like:
  
  Event: change
  Selection type: jQuery Selector
  jQuery Selector: td [headers = "FISHCOUNT"] select
  Condition: above
  Value: 1
  
  So far so good. But where I'm stuck is how to reference the LENGTH field of the tabular form in the actions of TRUE and FALSE, so that when the change in the event product (FISHCOUNT), the LENGTH is disabled if FISHCOUNT > 1, or LENGTH is enabled if FISHCOUNT < = 1.
  
  SEO so the scope of the CASE of my tabular presentation in the actions of True and False, that's where I need help.
  
  Thanks in advance!
  
  I use APEX 4.1.1

  John,

  You can do this by creating another dynamic action with the event 'Front Page submit' ("framework events" section).
  With real action that executes javascript, load the page uncontrolled.

  $("input:visible:disabled").prop("disabled",false);
  

  This will select all elements disabled entry visible on the page and remove the disabled property.

• change the results of the report with the selection list using dynamic action

  This is one of those situations where if I could understand the appropriate search terms to use, someone else must have asked this question in the past.

• Prevent fireing "Submit BeforePage" - dynamic Action if I click the button CANCEL

  Hello
  I create a dynamic Action on the event "before submitting the Page" which shows me a "Please Wait" - window, if I submit a page. It works very well.
  
  But if I click the button CANCEL, dynamic Action runs as well. Because of that I put the status "request is NOT contained in the Expression 1" and 1 Expression I put BACK, because demand from the button CANCEL is BACK. Unfortunately it is running if I press the button CANCEL.
  
  The action is "executing JAVA-code" and the code is:

  $x_Show('AjaxLoading');  
  window.setTimeout('$s("AjaxLoading",$x("AjaxLoading").innerHTML)', 100);

  What's not here?
  
  Kind regards
  Mark

  Hi Mark,

  If you change your button 'CANCEL' to a "Redirect to the page of this application" button, the page is not submitted and does not fire the event "before submitting the Page.

  Or if you want to stick with the shipment, you can check for this.data in JavaScript code because that will contain the value of the application to send it. So, for example, you could use

  if (this.data != "ZURUECK") {
    $x_Show('AjaxLoading');
    window.setTimeout('$s("AjaxLoading",$x("AjaxLoading").innerHTML)', 100);
  }

• Interactive report case triggering a dynamic action

  Hello

  My interactive report is built, based on the following query

  SELECT ID_OPERACION, NOMBRE_CLIENTE, TOTAL_PAGAR, APEX_ITEM. CHECKBOX (1, O.ID_OPERACION, "onclick ="f_UpdateCollection (this)"', a.c001") "Seleccionar"

  OPERACIONES o, apex_collections a

  WHERE the a.c001 (+) = O.ID_OPERACION

  and a.collection_name (+) = "OPE_COLLECTION".

  
  

  I use a collection because I don't want to lose the selected controls caused by paging.

  
  

  I would like to add a dynamic action that each time check box is selected, an element (P5_TOTAL_SELECCIONADO) summarizes the column TOTAL_PAGAR of all the checkboxes that are selected and each time a checkbox is unchecked the Total_seleccionado subtracts the value of the selected item.

  
  

  How can I do?
  

  Hi Eva,

  Please check again your application and see if it's what you thought.

  I made a few changes. First, here you were talking about P5_... the elements in your workspace apex.oracle, the page number is 1, so I changed the P5_... elements of P1_...

  Then, you let the fire on the boxes page laod on, but you don't want t function to begin to evaluate during page loading.

  There were also a few errors in the javascript code, I suggested. The VALOR_PAGAR selector was not correct, I've changed a little bit. Also all selected text values are strings and adding javascript strings will be just concatonate them. I made string number conversion for you, also taken into account that null values (P1_TOTAL_SELECCIONADO on page loading is null) cannot be cast to number.

  The result is:

  var VALOR_PAGAR = $(this.triggeringElement).closest('tr') .find ('td [headers = "VALOR_PAGAR"]') .text)

  var TOTAL_SELECCIONADO = $v ('P1_TOTAL_SELECCIONADO')

  VALOR_PAGAR = (isNaN (parseInt (VALOR_PAGAR) = VALOR_PAGAR)? 0: VALOR_PAGAR)

  TOTAL_SELECCIONADO = (isNaN (parseInt (TOTAL_SELECCIONADO) = TOTAL_SELECCIONADO)? 0: TOTAL_SELECCIONADO)

  var total = VALOR_PAGAR + TOTAL_SELECCIONADO

  $s ('P1_TOTAL_SELECCIONADO', total)

  This is the code to add checkboxes checked, false action is the same except for total, which is:

  var total = VALOR_PAGAR - TOTAL_SELECCIONADO

  Kind regards

• 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

• APEX 4.0.1: restriction on the maximum number of dynamic actions on a page?

  Hello
  
  I would like to know if there is a restriction on the number of dynamic actions on a page.
  I have a page with 29 dynamic actions. Everything works fine on the page.
  If I create another dynamic action that display only an alert or nothing else, I have the HTTP 404 error message when I try to view the page.
  If I delete the old dynamic action and create a new one so that the page works fine.
  After several tests, it seems that there is a maximum number of DA on a page, but if someone can confirm that?
  
  Environment:
  APEX 4.0.1
  Embedded PL/SQL gateway
  
  Kind regards
  SDDC

  Hi sddc.

  There is no limit on the number of dynamic action that you have on a page, but it is very likely that you hit a size limit of a variable we use during the generation of the JavaScript code for the dynamic actions. You can activate a log more detailed error further details on your 404 error - see http://www.inside-oracle-apex.com/oracle-apex-got-404-not-found-2/ EPG instructions are in the comments.

  BTW, you might be able to reduce the number of you dynamic actions by specifying page several items in the attribute 'Product (s)' from the 'when' the article if all run the same code. Just separate them with a comma (no spaces). Such as: P1_MGR, P1_DEPTNO

• Dynamic action does not work with the item change event

  Hi guys,.
  
  I have a problem with the dynamic Action. On my page, I have three points. (P2_X-> display only, P2_Y-> P2_Z-> button, TextField) and two dynamic actions. One of them is running javascript. When I press the button (P2_Z) this dynamic action affects textfield (P2_Y) value to display only the value (P2_X). (This dynamic works). And there is another dynamic action for the option to display P2_X. This dynamic action fires to P2_X point value changes. This DA (dynamic action) runs a plsql code and inserts the value of the P2_X element in a table (test_tbl). But when I try to do it always inserts the null value.
  
  The plsql code is below:
  
  Start
  INSERT INTO TEST_TBL
  VALUES (: P2_X);
  COMMIT;
  end;
  
  
  You have an idea? If you need, I can give the user for apex.oracle.com past.
  
  Thank you

  Hello

  Do you have the "points Page to submit" to the process of PL/SQL, the value of the correct item? (P2_X)

• Dynamic action - two types of options of "condition"?

  I would like to create a dynamic action that runs when a SQL condition exists is met.  If this is the case, then it will run several true Actions.  If this isn't the case, it will run several wrong Actions.

  I see there is an option of Condition in the when section of her DA, however, seems to be limited to static value comparisons or Javascript.  There is also another section of Condition where you can select SQL exists or various other PL/SQL expressions.  What is the difference between these options two condition?

  Also, when I set the status section to Exists and in the SQL query include an equivalence to an element of the page it does not seem to recognize the value of the page element. For example:

  Select * from my_table

  where PARTY_NUMBER =: MY_PARTY_NUMBER

  It still fails the condition even when a valid part number is entered on the page (him DA is run when MY_PARTY_NUMBER is changed).  I should be able to enter a reference point of page here, Yes?

  Thank you

  N ° you won't achieve what you're trying to do. The standard Condition section in dynamic action controls if the code of the dynamic action is rendered the see page. It has no impact on the question of whether the actions of true or false are performed during the intervention of the user. Control conditions which are those defined in the when the properties of the dynamic action. As they are evaluated in the browser, they must be specified as JavaScript.

  To perform actions conditionally based on the existence of rows in a table requires DA type body of the PL/SQL function or SQL, submitting the values of the requested page, runs the necessary query and returns a value to an element of [probably hidden] page, followed by either an action to run Javascript Code containing conditional logic , or another DA triggered by a change on the hidden element event.

• Infinite loop of dynamic Action

  Hello
  
  I have a page with the number of days, start date and end date.
  If I change the number of days, I want to put the end date, based on the start date + num days.
  I also want to go in the other direction, so if they enter an end date, it will calculate the number of days.
  I have dynamic measures for the latter and both work very well. The problem is that I get a stack overflow error a second about. I guess it's stuck constantly running dynamic stocks 2 one after the other, each triggering the each other.
  
  Does anyone else have this problem? And how do solve you it?
  
  Thank you
  Richard

  Hi Richard,

  I would stick with your PL/SQL code to perform the calculation and follow these steps:

  
  
  1. Create something hidden, that will be used to store the calculated value.
  
  
  2. Ensure that your 'set value' sets the value of the element hidden, with the result of your calculation of PL/SQL.
  
  
  3. In the same dynamic action, create another 'Action', that fires after the 'value of the value"which copies the value returned in the element of the corresponding page. Use the action type 'Execute JavaScript Code', with something like the following:

     apex.jQuery('#P1_END').val($v('P1_HIDDEN'))
     

  
  
  
  This should circumvent the problem of infinite loop and still allow you to use PL/SQL to do the math. I also added an enhancement request to allow optional triggering of the 'Change' event deletion when you use the action type "set the value, in order to more easily avoid this type of scenario. Is considered for a future version of the APEX.

  It will be useful.

  Anthony.
