• How to set the default value in the select list to cascaded

  Hello
  I use Denes Kubicek cascade example list of selection http://htmldb.oracle.com/pls/otn/f?p=31517:119
  
  And I want to give cascading the selection list with a default value. So, anyway, I use this application process:
  
  < pre >
  BEGIN
  OWA_UTIL.mime_header ("text/xml", FALSE);
  HTP.p ('Cache-Control: non-cache');
  HTP.p ('Pragma: non-cache');
  OWA_UTIL.http_header_close;
  HTP.prn ("< select >");
  HTP.prn ("< option value ="' | 1 |) "" > ' | '- all employees-' | ' < / option > ");"
  
  FOR c IN (SELECT ename, empno
  WCP
  WHERE mgr =: cascading_selectlist_item_2)
  LOOP
  HTP.prn ("< option value ="' | c.empno |) '">' || c.Ename | ("< / option >");
  END LOOP;
  
  HTP.prn ("< / select >");
  END;
  < / pre >
  
  How can I select for example empno default 1000?
  Thanks in advance.
  Jacob

  Jakob,

  In this case, your default value is

  HTP.prn (')' || "- All employees - | '');

  However, you can set the default value in the loop as you want. You just say that is your default - first, second, third...

  In the list select ajax there's no submit and no calculation of values then I assuem your default is the punch one you wan to display when a selection list has been changed?

• Need help to select lists in cascade and Update button in IR

  Hello
  
  I try to use cascading Select lists in a form that is called when the button update (see photo) is pressed in an IR problems I encounter are 2:
  
  1. during execution of the first of the form (that is to say by pressing the update or create in IR), the first Select list values but the 2nd is empty. If I change the value of the
  Select the first list then 2nd fills with the correct values, etc. I want the two 1st AND 2nd list to fill in the entry on the form.
  
  2. in addition, while pressing the button update, the 2nd list select do not seem to have the correct value selected, that is, the value that is actually in the database (IE in the)
  database file), but always the 1st available in the select list 2. The value of the select list 1 is always that of the recording.
  
  Any help will be appreciated. The following information:

  Ok. Now remove the javascript code that has been added in the footer.
  Change the LOV query for the 2nd item in list be

  SELECT descr_local descr_local, id of

  WHERE iface_protocol_id =: P63_IFACE_PROTOCOL_ID

  Set the Source used for this item "Always, replacing any existing value...". »

• How a select list to cascaded in a table?

  Hello

  I would like to know how to create a pick list cascading tabular.

  In the screenshot next, for example, when select "2081: Alice Fan", the next filed should watch only "ID: name of the element" belongs to Alice.

  

  Usually I do this simply for an article by implementing the SQL query and cascade LOV parent as follows.

  However, I can't find it in the form of tables?

  

  

  One can help with the solution?

  I hope that this can be done to reload partially after the first field had changed, but not to present an entire page.

  Thank you!

• How do the default editing a selection list after a change in another list of selection is made (not in cascade LOV).

  Hello

  I searched for the answer for a while now, but could not find a solution to my problem. It's a rather trivial issue, but after dealing with more urgent problems, I stuck with it and I can't move forward I use Apex 4.2.1

  OK, lets start with a description.

  I have two selection lists. After making a choice in the first, I would like to than the second value to change. It is not cascade LOV case, however, at least I don't.

  Let me give you an example. Suppose we have a table with name and default to the occupation.

  Name	By default occupancy
  John	Doctor
  Mark	Firefighter
  George	Firefighter
  Tom	Concierge

  End user first selects the name in the first list, then the occupation of another. It's perhaps not clearly in the example given, but the order of the questions.

  What I want is to force a change in the second value in the list after a choice in the first. So after the name is chosen, the occupation should switch to the default.

  The assignment is the most typical, but not the only one. So I want the end user to be able to change the occupation if necessary. Tom of sense is not to be janiotor, it can be whoever he wants this is why it is not cascade LOV problem.

  I tried with dynamic action - definition of value and then refresh. It works when the second selection list is the text field. I can't find a way to make it work with another selection list.

  Hope you can help.

  Concerning

  AEMs salvation,

  What I wanted with display and return value, you usually have a list of selection like this query:

  SELECT occupation d, occp_id r

  OF professions

  If your return value is an identifier. To use the text as return value is rather rare. Where my question, because obviously you must select the return value in your query, NOT the display value.

  So let me explain what is a set value. It takes the value of the server by using your query and AJAX in the background, then uses Javascript to set the value of the item in the browser.

  At this point your selection list still has the OLD value in the session. Then, you do a refresh and the element uses the old value, and it seems that nothing happens.

  So solution:

  -clear default values, you don't need those

  -get rid of refresh it in your DA

  Kind regards

  but I don't know how to get the value of DL_DETAIL_PROJECT_ID?
  
  Also the list of regular article values of the shows an option for cascading lists, but the form of tables, list of the values section is not, is it possible to have cascading lists in a record on a tabular presentation?

• In the form of cascading select lists - what am I doing wrong?

  Friends,
  
  Hope you can help, I'm trying to figure out how to build a tabular presentation that contains the cascading select list.
  
  What I do is to reproduce the excellent example Denes Kubicek has developed here: http://apex.oracle.com/pls/otn/f?p=31517:176 in my own work space.
  
  While I can see it working on the environment hosted by Denis, I can't make it work in my area. I must be missing a step (or several!) After trying in vain to operate for several hours, now I'm hoping you can help.
  
  That's what I did:
  
  Created a sql report using the exact same sql provided.
  
  Created a process page (rendered page side) using the same code.
  
  Added javascript code to my html page header section
  
  Created a process of application, called tab_casc_sel_list which runs on request
  
  When I run the following page occurs:
  
  The select deptno list shows 'Research' while the employee select shows 'Ford '.
  
  However, when I change the selection dept list I get the following results:
  
  Use Internet Explorer: The list of selection used now becomes empty and shows no entries
  
  The use of Firefox: the employee entries are still posted, but they are not restricted by Department.
  
  What did I miss?
  
  Thanks in advance for any help you can provide.

• Help with cascading pop-up list on slot form of table

  I'm new to APEX (on APEX 5.0) Please bear with me!  Let's say I have a tabular form with 4 columns (A, B, C, D)

  Here's the logic:

  1 column A is just a static list of 2 values.

  2 column B is determined by what you choose in column a.

  3. column C is determined by what you choose in column A and column B

  4 D column is determined by what you choose in column A and column C

  
  

  I need a list of popup cascading for columns B, C and D but since its under table, with several lines it is difficult.  I followed this link:
  

  Jari APEX blog: 'cascading' list Article on slot form table

  I was able to get the above to work in my application to meet business #2 logic, but I can't figure out how to make it work for the logic #3 and #4 because there are several critical values.  Is there an easier way to do this?  Can someone help me understand what the javascript code does in the link above?

  More precisely:

  (function ($) {;})

  / * Cascading pop-up list * /.

  $.fn.htmldbCascadePopup = function (parent, tempItem, options) {}

  options = $.extend({)

  loadingTxt: 'Loading... '. »,

  loadingCss: {'width': '80px","float": 'left'}

  (}, options);

  return this.each (function (i) {}

  var $self = $(this);

  $anchor = $self.next ("a").

  $parent = $(parent) .eq (i).

  popupFn = new Function ($anchor.attr("href").substr (11));

  $parent.change (function () {$self.val("").effect("highlight",{},2000) .focus () ;});})

  {$anchor.click (function (e)}

  e.preventDefault ();

  var parentVal = $parent.val ();
  

  if(!parentVal) {parentVal =' ";};}

  Apex. Server.Process ("DUMMY", {}

  p_arg_names: tempItem,

  p_arg_values: parentVal

  },{

  data type: "text",

  beforeSend: function() {}

  $self

  . Hide()

  .after ($("< div/>", {"html":options.loadingTxt,"la classe css":options.loadingCss",": "ui-saisie semi-automatique-chargement"})

  . Width ($self.outerWidth ())

  . Height ($self.outerHeight ())

  );

  },

  complete: function() {}

  popupFn();

  $self

  . Show()

  . Next ("div. UI-AutoComplete-Loading")

  . Remove();

  }

  });

  });

  });

  };

  (}) (apex.jQuery);

  I have a Monday deadline for this so my time is up.  Here's what I did to help someone, even if it has a very quick and dirty solution.

  After the example of Jari blog work, I learned the following: Popup LOVs have a display value and a return value.  They correspond each to their own field in tabular form.  For example, the display for my column 'B' column is f10 and the back column is (hidden) f09.  Column C depends on A and b.  So, I did the return value of B for the concatenation of A & B.  Then I pass that value into a variable of the APEX with Jari javascript and try the parse to the LOV for column C.

  It gives me values in the table that I don't really want.  If column A is supposed to be "12345" and column B is supposed to be "XXXXX", then the value in column B is "12345". XXXXX. "  So I'll make a post process clean.

  All this could be increased if I know enough javascript to add multiple parameters to the code of Jari.

• Selection list cascading in the dialogue window

  Hello

  I'm developing in Apex 4.2.5.

  I have an Apex with a classic report region, in which a link edit page opens a dialog window (in the same page apex) to edit the selected line. The same dialog window is used to create a new line. The dialog window contains a cascading pick list. Two selection lists are defined to display NULL values and correctly fill in mode 'create '. My problem is that mode "Modify" the list of the second selection is not good value. The second selection list contains it however the right subset of values according to the parent, select the list and therefore don't does not contain the correct value, but it is not selected.

  I use a javascript function to fill in the fields in the dialog.

  ....

  $s ("P3_EVENT_TYPE", arguments [1]);

  $s ("P3_EVENT_SUBTYPE", [2] arguments);

  ....

  Then the display of the dialog window

  openDialog ('editEvent');

  
  

  The population of P3_EVENT_SUBTYPE list seems to happen but sometime after that all the fields in the dialog were assigned and the dialogue window displays.

  I see that I need to somehow update the list of selection in cascade, P3_EVENT_SUBTYPE, before assigning the value. My problem is how can I do this in the same javascript function?

  Kind regards

  Derek

  Eventually answered my own question-

  I created a hidden field in which to store the value of the event subtype.

  Created a dynamic of Action, after refresh of affected P3_EVENT_SUBTYPE subtype value = hidden field event.

• Can a selection list cause two lists of parent of Cascade?

  4.2.1

  THM:2

  Hello world

  I have two regions

  Region 1 has a selection list and a text called order box and category of the order. There could be several orders in a category. When I choose a selection list order, he fills the text box with the corresponding category by using dynamic "SetValue".

  Now, I also want the second region that has an another LOV orders, fills only order_ids not selected in region 1 LOV however, it should show only other orders in the same category.

  So something like select commands from P4_ORDERS1 where category and <>P4_ORDERS order_id = P4CATEGORY

  But seems to not work. I created this on Apex

  https://Apex.Oracle.com/pls/Apex/f?p=64292:4

  workspace: ryansun

  user: [email protected]

  PWD: ryansun123

  Ideally, when I select the No. 1 of the order of P4_orders, P4_ORDERS1 should show 4 for the other order_ids, that p4_orders1 will be null.

  Thank you

  Take at look at page 5 and 6.

  Page 5 the query for the LOV P5_ORDERS1 was modified to use the value of P5_ORDERS.  Not really necessary to include the value of P5_CATEGORY

  Page 6 the parent element is P6_CATEGORY for the LOV is updated when the value of P6_CATEGORY is modifed by the dynamic Action.  Dynamic Action will present the P6_ORDERS value in session state to be used by the LOV P6_ORDERS1.

  As for the original question in the title, a list of selection may have two lists of parent of cascade? The answer is Yes.  You can include 2 (separate control) in the area of the waterfall LOV article Parent (s).

• Possible a bug of cascading select list

  Hi people,

  I created a dynamic action "onChange" in a page called "P5_COD" element Always of value of "P5_COD" changes, it runs the PL/SQL code above to fill the page elements with data from database:

  Select

  PERIOD,

  BEGIN_DATE,

  END_DATE

  in

  : P5_PERIOD,.

  : P5_BEGIN_DATE,.

  : P5_FINISH_DATE

  Of...

  BEGIN_DATE and end_date are page elements "selection list. They are "Cascading LOV Parent article (s)" of the PERIOD (select list too).

  The problem is: 'onChange' dynamic action doesn´t work to load the elements of page BEGIN_DATE and end_date.  BEGIN_DATE and end_date loading default data, not the data of database.

  Any idea?

  Thank you

  First of all the code you listed does not change the value of objects client only in session state-side. In other words only on the server.

  Use a dynamic action of type 'Set value' to change the value on the client side.

  Then change the value of P5_PERIOD will trigger the change of the P5_BEGIN_DATE LOV: P5_FINISH_DATE and the values of these elements are initialized to null (client side only).

  In a similar challenge to define the value of the mother and child at the same time, I'm done setting the value of the child element in a hidden item. And on the afterrefresh event of the child, the value is set to the child.

  See this demo , I realized for the challenge.

• Editing cascading from the selection list - not refreshing during the loading?

  Hi all
  
  I have 2 lists of selection, the latter with an option cascading of LOV.
  
  Now, this works very well when you select an option in the list 1, list 2 fills correctly.
  
  My question is when I re - complete list 1 and list 2 from a single onload procedure 1 load properly, list 2 does not show the correct value (but it has not the right value is session).
  
  This feature exist?
  
  Please let me know if you need more information.

  Hello

  You have the following items in the pl/sql code of DA:

  begin
  select parent_id, child_id
   into :p1_parent, :p1_child
  from holder
  where parent_id = 1;
  end;
  

  You have the following in the query LOV's P1_CHILD:

  select col2 d, col1 r
  from child
  where col3 = :p1_parent
  

  P1_parent = 1, the LOV query returns 2 rows - DUNDEE and GLASGOW. The list of selection, therefore, cannot set a value. I changed the order of the day of the P1_CHILD page for a multiple-selection list and it works fine now.

• Help with dynamic action and the selection list item

  G ' Day Apex gurus.
  
  I have problems trying to achieve to trigger the Help window from an element automatically select. A Help window is triggered when it is clicked on the label of an item, but my customer wants to be triguered automatically as soon as the user clicks to view the options in the select list.
  
  I think I should be able to do with dynamic actions but I can't function.
  
  I know when someone clicks on the label of the item selection list trigger this JavaScript
  
  JavaScript:popupFieldHelp('277938589795252851','1545903379570909')
  
  So I want to trigger the javascript also when the user click on the item selection list and pull down the options and for that I think that the dynamic action is the way to go, but I can't do things.
  
  That's what I have to do:
  
  I created a dynamic option as follows:
  
  Name: test
  Sequence: 30
  Even: click
  Selection type: product (s)
  Article (s): P1_RATING <-a selection list item
  Condtion: - no requirement.
  
  Real Actions
  Sequence: 10
  Action: Run the JavaScript Code
  Fires when the result of the event is: true
  Fire on loading the page: checked
  Code: javascript:popupFieldHelp('277938589795252851','1545903379570909')
  
  Thank you anyone who can tell me what I'm doing wrong here or bring a solution to my problem to trigger the Help window from an element automatically select.
  
  Kind regards
  Carlos

  Hi Carlos,

  I've set up a test case of exactly in the same way and it worked fine for me. I've created a page element called P1_DA_DEMO and added some values of the static selection list, then added a help text. I used the settings are lower, I suggest you try again, but also make sure that you have no other Javascript errors on the page. Use a tool like firebug to check.

  Name: Action Dynamics demo
  Sequence: 10
  Even: click
  Selection type: product (s)
  Product (s): P1_DA_DEMO<- a="" selection="" list="">
  Condtion: - no requirement.

  Real Actions
  Sequence: 10
  Action: Run the JavaScript Code
  Fires when the result of the event is: true
  Fire on loading the page: unchecked
  Code: javascript:popupFieldHelp('277938589795252851','1545903379570909')

  Scope of the event set a Bind s.

  Thank you

  Cascade of LOV... reference http://andrejusb.blogspot.com/2008/12/cascading-lovs-in-oracle-adf-11g-update.html
  In the right table defined the PRR on the component of column 1, column 2. Also set the AutoSubmit/PartialSubmit for the component of Column1.
