Loading list select cascade lov

• 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

• 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!

• Handling cascading LOV (multi-Select parantes LOV)

  Hello
  
  I use LOV cascade.
  
  P1_PARENT - Parent LOV (i.e. multiple selection)
  P1_CHILD - child LOV
  
  LOV Parent being multiple selection, so it will have the following values... P1_PARENT = AA:BB:CC
  
  and where clause in the LOV cascading should be like

         where col1 in (:P1_PARENT)
     

  -How to convert the element value for P1_PARENT of AA:BB:CC to "AA", "BB", "CC"
  - Is there an another way manage in cascade LOV (to select several parent LOV).
  
  Select the list of P1_CHILD

   
      select d, r
    from test
   where col1 = :P1_PARENT
   where col1 in (:P1_PARENT)

  Thank you
  Deepak

  Hi Deepak,

  In where clause for the LOV child, you can use instr function as:

  (instr(':'||:P1_PARENT||':',':'||col1||':',1) > 0 ) 
  

  To access the individual elements in the multiple selection: P1_PARENT, you can use:

  DECLARE
  
  l_selected HTMLDB_APPLICATION_GLOBAL.VC_ARR2;
  
  BEGIN
  
    l_selected := HTMLDB_UTIL.STRING_TO_TABLE(:P1_PARENT);
    FOR i IN 1..l_selected.count
    LOOP
          //  your code here...access individual elements using  l_selected(i)
    END LOOP;
  
  END;

• Apex 4.0 Cascading list Select: ajax with umlaute German problem

  Hello world
  
  Apex 4.0
  Papa PlsqlNLSLanguage: GERMAN_GERMANY. WE8MSWIN1252
  
  I have problems with German umlaute and selection in ajax cascade (cascade LOV Parent article) lists.
  Data are filled in the selection list without a page refresh when the parent select list of changes, but specific signs such as the German umlaute are also weird characters.
  Looks like there is a problem of charset with ajax.
  
  It is the only part of the application where the specific signs such as umlaute are messy. Everything else is fine.
  
  I already tried to figure out if I can escape the umlaute in javascript (file apex_widget_4_0.js) but without success here.
  
  Can someone help me with this problem?
  
  Thanks in advance,
  Markus

  Hi Markus,.

  your character specified in your DAD won't. As mentioned in the http://download.oracle.com/docs/cd/E17556_01/doc/install.40/e15513/otn_install.htm#CHDHCBGI installation instructions, APEX Oracle always requires AL32UTF8.

  >
  3. look for the line containing PlsqlNLSLanguage.

  The PlsqlNLSLanguage determines the language setting of the DAD. The character portion of the PlsqlNLSLanguage value set must be set to AL32UTF8.
  Although the character of database set AL32UTF8. For example:

• problems with customization select lists and popup LOVs

  Hello
  
  
  I have 2 problems on selection lists and popup LOVs.
  
  The first is on a list in tabular form.
  It must be created with APEX_ITEM. SELECT_LIST_FROM_LOV or similar and take its values of a named LOV.
  This worked fine, but now it should also have the possibility to enter a free value.
  I tried to accomplish this by creating an APEX_ITEM. POPUP_FROM_LOV, but there is a problem with the function which is called the icon of the right arrow to the input field (for eg. genList_f11_5()).
  If the line is added by addRow, then it works fine, but if the line is not empty
  Then the function call is as genList_f11_$ _row () and the input field becomes worthless, when an LOV is selected.
  
  
  The other problem is on a list of selection that should have the opportunity to enter a custom value and
  It should also be able to select multiple values. I tried to implement this in a text box that contains the selected values, and a multiple select list, with an event handler in each option. The user can click on options and they would be copied into the text box. The problem is that I couldn't make the event handler works in Internet Explorer.
  
  I would like ideas on one of these problems.

  Hello

  It can be created at APEX_ITEM. TEXT.
  APEX_ITEM also generates the name attribute that I use the jQuery selector in the sample.
  Use jQuery UI autocomplete just similarly as in my example with APEX_ITEM

  How can I select for example empno default 1000?
  Thanks in advance.

  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?

• In cascade LOV - Dynamic action time-out

  See https://apex.oracle.com/pls/apex/f?p=57688:32

  X 1 selection list is set 1,2,3

  X 2 a parent selection list cascading as X 1 and ajoute.1/.2/.3 to X 1

  There is a change DA on the text field to set the 2 selection lists to the value set in the text field. For example, if I set the text field to the 1.2 version, I want X 1 to 1.2 to 1 and X 2. There are therefore 2 actions to set the value; first of all to define X 1 and secondly to set X 2.

  The problem is that when X 1 is set, the change event on X 1 fires and refreshes the LOV for X 2 and the 2nd real action should fire after the LOV refresh but (probably), it fires too early and not ends not change the value of X 2, so it remains empty. I tried assigning no on the first real action to remove a change event, but that will not work because I need the modification to the fire action when X 1 changes to the LOV to X 2 can be updated.

  The annoying thing about this is that it works sometimes (X 2 is set correctly) and sometimes does not (X 2 remains empty). I guess it depends on timing of millisecond level between when X 2 refresh is complete and the 2nd shot of real action.

  What this kind of thing done? Almost need a sleep/delay after the first action to set the value so that the change/refresh LOV event to take place and then run the action to set the value to 2. But the presentation with the help of setTimeout and similar delays can ruin the execution has / synchronous Javascript engine and crash the browser so I am reluctant to go this route...

  Help? Thank you

  Select cascading lists work correctly with the principle of cooling they are triggered in the front and after the events of refreshment. You can link to this event, and then set the value.

  Your first action is a defined value which is synchronous and triggers a change event.

  Here is a pure js to take on this:

  $("#P32_X1").on("change", function(){
    // do something when X1 is changed
    console.log("change x1");
    //wait for X2 to finish refreshing before setting its value
    //.one() will bind a handler which will unbind after it hass handled once
    $("#P32_X2").one("apexafterrefresh",function(){
      apex.item("P32_X2").setValue("1.1");
    });
  });
  
  //when text changes and set a value on X1
  //setValue already fires a change event
  $("#P32_TEXT").change(function(){
    apex.item("P32_X1").setValue("1");
    .change();
  });
  

  To do this in your DA, you bind the time Manager to the second list before leaving the event which it will update. I would not put it in a DA on X 1 because this event of change may occur when it is too late already (may, may not - asynchronism), simply because there is already a change on it due to cascading select lists event handler. So ideally, before you trigger the change on X 1 event and, therefore, during the change of Manager of the TEXT.

  $("#P32_X2").one("apexafterrefresh",function(){
    apex.item("P32_X2").setValue("1.1");
  });
  

  You will need to define what is set as the value of X 2 of course, that you have given, I can't tell what it is, so I've hardcoded value (and FYI my value will work only if X 1 made 1, of course, because only then be X 2 hold 1.1).

  Some links to docs:

• Double output on Cascade LOV

  Hi all.
  I spent 3 days of testing in this case, I have the script online at:
  
  http://Apex.Oracle.com/pls/Apex/f?p=78875
  
  I have 3 LOV:
  
  #1 is just ok
  #2 needs value between 1 # (returns a copy)
  #3 requires value of #2 (returns duplicate also)
  
  The user for the development is test/test123
  
  I really appreciate any help you give me.
  
  my version of the apex is 4.2 also
  
  Thank you!!

  Well, I agree, it was weird enough I just had to take a look. I saw fire ajax twice for very strange select statements.

  Snooping in your template page I noticed that you had commented on the #BOX_BODY tag #.

  #BOX_BODY # is mandatory, so I put back it. I think you could fool APEX because you had it on the page, but it was all inside of a comment.
  in any case... I do not fully understand why JS code that refreshes selects it was added twice to the page, but it's fixed now. :)

  Just make sure that you have your BOX_BODY tag in all your pages. Even if you don't want to use it. :)

  Oh and FYI, the elements need not be added to the Articles Page to submit because the list of element Parent of Cascade LOV already takes care of this.
  Assistance on the ground + "you can then use these page elements in the where clause of your SQL statement"list of values"". "+"

• In cascade LOV and calling a javascript function thro dynamic action

  We have a page where there are lovs cascaded to the country / state. The selection of State list is cascaded with country LOV. We also request a javascript to normalize the child lov (State), so that if there is no value in the list, the lov will be disabled and if there is only one value for show, which will be set as default (enabled). However, it seems apex runs javascript code standardize everything first and then generates the list for the lov State, then the State lov is always disabled.
  
  I created a page similar to apex.oracle.com with choice of Department lists and employee. The link to the page is http://apex.oracle.com/pls/apex/f?p=40631:2
  
  In this page, the employee selection list is cascaded to the Department. (1) to any value other then 'IT' or no selection value in the list of DEPARTMENTS, the list of employees must be enabled and should list all the names of appropriate employees. (2) for the selection of the 'IT', it should be disabled with the default selection as "no data found". However it does not for 1). Could someone find the problem and give a possible solution.
  
  Javascript code executed (that thro NatStandardizeLOV1('P2_EMPLOYEE') dynamic action for Department change is lower.
  
  < code >
  function NatStandardizeLOV1 (pitem)
  {
  var obj = document.getElementById (pitem);
  obj. Disabled = false;
  obj.options [0]. Text = "SΘlectionner one..";
  
  
  If (obj.type is "select one")
  {
  
  If (obj.length == 1 & & (obj.options [0] .value == ": obj.options [0] .value == null))
  {
  obj.options [0]. Text = "No. Data."
  obj.disabled = true;
  }
  If (obj.length == 2 & & (obj.options [0] .value == ": obj.options [0] .value == null))
  obj.options [1]. Selected = true;
  }

  Natarajan,

  The question is one of the time. You're service is running before the Ajax request (triggered by the LOV cascading) brings back the items. So change the 'when' of dynamic Action so that it fires the event "After Refresh" of the question of the Department rather than the event change.

• Apex 4 Cascading LOV s how to define a child LOV back to the null return value

  Hello
  
  My problem is that I use the new dynamic action to implement features of LOV cascading to the Apex 4 which means not having to submit the page to update child LOVs after parent LOV changes.
  
  What I find, is that when you change the value LOV parent, then the child LOV (which has a return value of zero) is not or by default in the return value zero (in my case no selection should return-1) if the list is filtered to a different set of values, which is not a selection valid. The LOV child is left without a choice when I need its default value to the return value zero (-1, which represents all values).
  
  Also, I expected to do before the page is sent and filtering to the bottom of the hierarchy of LOVs can work when the child is zero (-1, which means that all values) and in turn her child LOV (s) will also the child null filter.
  
  Any help would be appreciated.
  
  Thank you

  Hi 804641,

  I don't know if I get your problem and I tried to reproduce.

  http://Apex.Oracle.com/pls/Apex/f?p=2672:6 is my example with a LOV cascading where I also defined a dynamic action that is triggered when P6_EMPNO changes and it shows the current selection.

  Maybe it helps if install you an example on apex.oracle.com and provide space to work/user/pwd, so that I can have a look. I'm not sure about your sentence "help for a new dynamic to implement cascading LOV feature", because dynamic actions are not necessary for LOVs cascading. It is a characteristic of the types of items themselves where you just set the attribute "Cascading LOV Parent éléments".

  Concerning

• Reuse cascading LOV in several pages?

  For example, if you page elements to make the car and identify the model, model car as element Parent LOV cascade so that every time the car has changed, the LOV for model would be updated. (Copied from documentation: P)

  Thus, the request for model car LOV is defined as

  select car_model d, car_model r
  from car_models
  where car_make=:CAR_MAKE
  
  

  And on the page, I establish a page CAR_MAKE and use it as the "Cascading LOV Parent article (s). So far so good.

  I want to use this LOV in another page. The problem is, APEX reject create me CAR_MAKE in another page, saying "name of the element is already used by another page or application.

  Addition of the LOV even for each page (only using linked different variable name), is there a solution?

  I thought to use a copy of the car to point application dynamic action game and referred to the point of Application in the LOV. Is it guaranteed that the dynamic action complete before the LOV is updated?

  Request Express 4.2.0.00.27

  If the parent element names differ only in the number of page as in your example, you can use:

  select car_model d, car_model r
  from car_models
  where car_make=v('P'||:app_page_id||'_CAR_MAKE')
  

  Beware that you add the element relative to Cascading article (s) Parent LOV because apex generator won't recognize him.

  In this way, that you don't have to change the standard LOV when used on a new page.

• Display data in Table a selection of LOV

  Hi all

  I have a scenario in which the JSF pages contains a LOV and table of the ADF.

  My requirement is to display the rows in the table based on the value selected in LOV.

  The table and the LOV were built out of same data control.

  I use Jdeveloper - 11.1.2.4.39.64.36.1 version.

  Tips gently on the way forward.

  Best regards

• Cascade LOV display text (based on LOV) report clasic

  Hi Experts,
  
  It is possible to use cascade LOV - item is displayed as text (based on LOV) in clasic report? (Display AS)
  I would like to refer to another column displayed in the report in LOV.
  
  Example:
  

  select description d,
         val_strg2 r
    from domain_cntr
   where cntr_name = 'CH_PRIM_ST_NOTE'
     and val_strg1   = #PRIM_STATUS#
     and active_idc  = 'Y'

  #PRIM_STATUS # is the column I would like to reference.
  
  Is this possible? IN THE CLASSIC REPORT

  J :D

  Hello
  >

  >
  Yes.

  It can one thing long enough to encode, so be prepared for that.

  Here's how:
  a. use the APEX_ITEM API in your report query. Be sure to only specify the p_item_id parameter, using #ROWNUM #.
  b. in the LoV wrtie Parent a trigger of onChange event which triggers a JavaScript function and pass it the ID of the item.
  (c) in this JavaScript function makes a call to get AJAX < select >... < option... >... < / select >, in short the full HTML of the child LoV
  d. push this HTML fragment in the child Lov. You build the ID of the target based on the ID of the parent. E.g. f01_0001 to f02_0001.
  e. you can further keep the invisible or disabled child initially and then make it visible/enable after it is filled.

  Kind regards
