• How to fix the value of table type defined on page of the ofa LOV

  Hello world
  There's a valueset created in the xx_ap_valueset to say front end which is of type table and created on a table xx_ap_table somewhere with cluase and stopped by the clause.
  
  Is there a way that we can reach this value a page of the OPS LOV? or is it just that I need to create a vo and reproduce the select statement used in the valueset.
  
  
  Help, please!
  
  Thank you
  Sunny

  Sunny,

  You can not attach the Valueset to the Lov directly. You must create a VO for this.

So can someone like me how... the steps... If someone can give me an exmple it would be greate...

  Hello

  best advice is to watch the demo of the component and customize their code. You will need to build a model for this, is an example in the demo. Sources for downloadable demo

• JavaScript allows you to create cascading LOV to the tabular report only works on level 1

  I'm trying to implement a LOV cascading to a tabular report.  I have been using an example by Denes Kubicek (https://apex.oracle.com/pls/otn/f?p=31517:315).  I am able to get this example works when I'm on the workspace hosted APEX (workspacehttps://apex.oracle.com/pls/apex/f?p=67254:1 = COA demo/demo).  The example works as expected in the space of organized labor.

  My problem is when I take the application and import in a workspace internal APEX LOV Cascading sets the value of the first row in the table report; However, it does not define the following lines, and it does not dynamically change the values in the first rows of LOV, when another Department is selected.  I also tested the results by exporting the application on internal site to the hosted site. It works perfectly on the hosted site, but not inside.  Our internal APEX site is running version 4.2.2.00.11.

  The JavaScript code that is executed in dynamic Action is:

  elem var = ' # ' + this.triggeringElement.id;

  var = key "#", "f02_" + this.triggeringElement.id.substring (4);

  var set_list = ' # ', 'f04_' + this.triggeringElement.id.substring (4);

  var key_val = $(key) .val ();

  var elem_val = $(elem) .val ();

  var selected_val = ";

  (apex). Server.Process

  "getEmployees"

  {

  x 01: elem_val,.

  x 02: key_val

  },

  {

  success: function {(pData)

  $(set_list).find('option').remove ();

  $(pData, fonction (clé, innerjson) {} .each)

  $(set_list) .append ($("< option >', {})

  value: innerjson. VALUE,

  text: innerjson.NAME

  }))

  If (innerjson. SELECTED! = ") {selected_val = innerjson. SELECTED};

  });

  If (selected_val! = ") {}

  $('select'_+_set_list_+_'_option').each (function)

  {this.selected = (this.text == selected_val) ;})} ;

  }

  },

  }

  );

  Is it possible that our internal environment lacks some features used in code? How can I check to see if we have a missing function?  There are other reasons that the two environments react differently?

  Any help would be appreciated.

  Thank you

• Shuttle value too long for use in LOV sql cascading

  Hello

  On APEX 4.2.2.0.11 & Oracle 10.2.0.5.0:

  I have a shuttle service set up as well as a select list with of LOV cascading.

  The shuttle shows organization name and returns a list of the IDs of the colon separated.

  The selection list shows the so-called events belonging to the organizations selected in the shuttle.

  The selection list is implemented as LOV cascading with the shuttle as a parent element.

  This works fine as long as the length of the shuttle point value does not exceed 4000 characters.

  If so, the LOV - sql select list will give an ' ORA-01704: string literal too long "-error on the instr function ().

  This is the query:

  Select distinct TST. NAAM as display_value, TST.ID as return_value

  of the OTE ORGS

  Join the LIFO ADG ON (ADG. OTE_ID = OTE.ID)

  Join the DNR PART on (DNR. ADG_ID = ADG.ID)

  Join the TDR ON REGRET (TDR. DNR_ID = DNR.ID)

  Join the TEST TCT ON (TST.ID = RDT. TST_ID)

  where instr (': ' |: P1_ORG |) ':', ':' || OTE.ID | ') > 0

  order by 1

  Does anyone know how to make reference to the shuttle-value in sql, even if it is longer than 4000 characters?

  Well, I found a way to use LOVs cascading on page elements with values exceeding 4000 characters:

  Let's say I have a shuttle named P1_ORGANISATIE with "List of values" box, a dynamic LOV named "Source: lists of values Query" containing the value:

  Select NAAM as display_value, ID like return_value

  of NINEHAM

  order by 1

  If the number of records-NINEHAM is insufficient, the length of the value of P1_ORGANISATIE, which is a list of concatenated with colon separated digital ID, can exceed 4000 characters.

  Now suppose I have a list of selection called P1_TEST that is connected through "List of values"-> "En cascade LOV Parent article (s)" with P1_ORGANISATIE using a named LOV dynamics with "Source: lists of values Query" containing:

  Select distinct TST. NAAM as display_value, TST.ID as return_value

  of the OTE NINEHAM

  Join the AFDELINGEN ADG ON (ADG. OTE_ID = OTE.ID)

  Join the DEELNEMERS DNR ON (DNR. ADG_ID = ADG.ID)

  Join TESTDEELNEMERS TDR WE (TDR. DNR_ID = DNR.ID)

  Join TESTEN TST ON (TST.ID = RDT. TST_ID)

  where instr (":" |: P1_ORGANISATIE |) '':'', '':'' || OTE.ID | '':'') > 0

  order by 1

  In this case, when P1_ORGANISATIE exceeds 3998 characters, you'll get an "ORA-01704: string literal too long"-error and the P1_TEST will show an element called "undefined".

  A way around this is possible because for a named LOV, you can use a "function that returns a sql query" instead of a simple sql query. In other words, we can apply in the context of PL/SQL and thus have maximum for expressions of 32767 instead of 4000 characters. In addition, it is possible to use the two APEX_UTIL. STRING_TO_TABLE and APEX_COLLECTION.

  Setting "Source: lists of query values" on the LOV appointed to P1_TEST with the following code will work:

  DECLARE

  l_selected APEX_APPLICATION_GLOBAL. VC_ARR2;

  l_qry varchar2 (32767): =.

  "Select distinct TST. NAAM as display_value, TST.ID as return_value

  of the OTE NINEHAM

  Join the AFDELINGEN ADG ON (ADG. OTE_ID = OTE.ID)

  Join the DEELNEMERS DNR ON (DNR. ADG_ID = ADG.ID)

  Join TESTDEELNEMERS TDR WE (TDR. DNR_ID = DNR.ID)

  Join TESTEN TST ON (TST.ID = RDT. TST_ID)

  $1

  order by 1';

  BEGIN

  IF: P1_ORGANISATIE IS NULL

  OR LENGTH(:P1_ORGANISATIE)<=>

  THEN RETURN

  Replace (l_qry

  ,'$1'

  ,' where instr (":" |: P1_ORGANISATIE |) '':'', '':'' || OTE.ID | '':'') > 0'

  );

  ON THE OTHER

  l_selected: = APEX_UTIL. STRING_TO_TABLE(:P1_ORGANISATIE);

  APEX_COLLECTION. CREATE_OR_TRUNCATE_COLLECTION (p_collection_name-online 'ORGANISATIE_COLLECTIE');

  FOR id IN 1.l_selected.count

  LOOP

  APEX_COLLECTION.add_member (p_collection_name-online 'ORGANISATIE_COLLECTIE'

  p_n001-online to_number (l_selected (id))

  );

  END LOOP;

  RETURN

  Replace (l_qry

  ,'$1'

  ,'join apex_collections ON APC (APC. COLLECTION_NAME = "ORGANISATIE_COLLECTIE" AND APC. N001 = OTE.ID)"

  );

  END IF;

  END;

• Question of LOV cascading

  Hi all
  
  I have a table that contains the data of students, with columns for the dorm, sports, racing section, floor living room and advise among others. I've implemented a LOV this list each of these columns, so the LOV is defined as:
  
  Display return value of value
  Advisor 1
  Section 2 of the FYE
  University residence 3
  University residence floor 4
  5 sport
  
  Now I want to set up a second LOV that lists the different values depending on which value is selected in the first LOV. So if counsel is selected, each Member of the faculty who is a counselor would be listed in the second LOV. If the Sport is selected in the first LOV, a list of all sports (Football, Baseball, Volleyball, etc.) would be listed in the second LOV.
  
  I tried the following to the second LOV, but it gives an error:
  
  IF: P8_GROUP = "1" THEN
  RETURN
  "select distinct sect of wlwrap where the sect is not null order by 1';
  ELSIF: P8_GROUP = "2" THEN
  RETURN
  "select distinct sport of wlwrap where the sport is not null order by 1';
  END IF;
  
  The error is: error during rendering of the element on the page P8_SUB_GROUP. ORA-20001: the query must begin with SELECT or WITH (P8_SUB_GROUP is the name of the element that uses the second LOV)
  
  Thoughts?

  Hi, wisers

  What version do you use? If it is 4 or higher, you can set the Cascading LOV article Parent (s) with: P8_GROUP in your second LOV and put in place of Page to submit items with the same value. After that, you must create a query like this:
  code here
  Select a separate sect
  of wlwrap
  When the sect is not null
  and: P8_GROUP = 1
  Union
  Select distinct sport
  of wlwrap
  where the sport is not null
  and: P8_GROUP = 2
  order by 1;

  I'm sorry if I do not use the tag for the code properly: P...

• Drop-down list LOV shooting required field validation

  Hello
  
  I use Jdev 11.1.1.6.
  My VO is based on entities. I have 3 domains in this VO as F1, F2, F3
  3 fields are required.
  F1 has Combo Lov-based model implemented. List attribute LOV lookupId returned to F1 and the attribute List lookupDesc at F2.
  F2 is mandatory and can be changed. Idea is that the default text returned by lov and then user can update the description.
  
  Scenario 1: does not work >
  During execution, in mode, create when I try to select a value for this lov combo, it triggers the validation of required field for F2 (only for F2 and F3 not) and does not display the list of values. I can't do to show the list to enter some data in F2.
  < af:inputComboboxListOfValues > a autoSubmit = 'true' and immediate = "false" and a partialTriggers F2 = "id of F1".
  
  Scenario 2: < work >
  For test purposes, if I do unalterable F2 it works perfectly but F2 is editable and mandatory as well.
  < af:inputComboboxListOfValues > a autoSubmit = 'true' and immediate = "false" and a partialTriggers F2 = "id of F1".
  
  Scenario 3: < work >
  On other pages, I've implemented combo lov where the lov is implemented on the reference field and the return value only the Id column and not in any other field. This scenario works perfectly, even with the mandatory fields on the page.
  < af:inputComboboxListOfValues > a autoSubmit = 'true' and immediate = "false".
  
  
  Thank you
  JAI

  Try to remove F2 partialTrigger (a partialTriggers = 'F1 id'),
  and join valueChangeListener on F1, in which you can refresh partially F2 (in code)
  Of course, do autoSubmit F1.

  Scenario 1:
  During execution, in mode, create when I try to select a value for this lov combo, it triggers the validation of required field for F2 (only for F2 and F3 not) and does not display the list of values. I can't do to show the list to enter some data in F2.
  a autoSubmit = 'true' and immediate = "false" and a partialTriggers F2 = "id of F1".

• LOV with modal window

  Hi all
  I need to implement a LOV with a link 'Add' that open a modal window to insert a new row in the table and return the value inserted in the LOV.
  
  Is there anyone to implement this feature?
  
  Thank you
  Sergio

  Ah, I forgot abt the part of the insert, we will need to refresh the LOV article first, and then set its value and then send the page
  Try

  $('#P1_LOV').trigger('apexrefresh');
  $('#P1_LOV').one('apexafterrefresh',function(){
    $s('P1_LOV', pk);
    apex.submit("REFRESH");
  });
  

• 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

  Hello
  I've implemented a LOVs 4 cascading in an app that fills in the correct data from the previous items. My problem is when I click on the search button to complete the registration data on the basis of the 4 values LOV cascading select list lose focus, they reduce to a minimum with no data. Someone at - he never experienced this and knows how to solve this problem? My list of Select cascading use processes of Application and JavaScript to fill in the values. I also use some methods of Application and Javascript based on research, the buttons back and forward to complete searchable data based on the value selected in the LOVs cascade. Help or knowledge is really enjoyed this question. I don't know if it an error in syntax or in the Select list is not searchable form using APEX values. I also have an example in any wants to take a look at the about, thanks again.

  Charles:

  The function "f_query_by_example" JS lent items with a tagname of "SELECT". I changed the line

  If (l_El.tagName == 'INPUT') {}

  to be

  If (l_El.tagName == 'INPUT' | l_El.tagName == 'SELECT') {}

  Good selection lists appear now.

• 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!

• SelectOneChoice show the correct value with switching problem

  Hello

  I use JDeveloper 11.1.1.5.0 and I have a non-trivial application of SelectOneChoice.

  Here's my usecase:

  I have to show LOV to set the State according to the connected person.

  So, I implemented attribute LOVs view that each filtered for in the light of the type of person (owner or non-owner).

  I created switcher LOV for attribute as java method in module impl invoked by EL expression adf.source.getApplicationModule () .getTaskStateLOVSwitcher (adf.object, CreatedByIdFk);

  to get connected user binded query parameter id.

  	public static String getTaskStateLOVSwitcher (ViewRowImpl, String createdById, time stamp dateInsert vri) {}
  	ViewObject vo = vri.getApplicationModule () .findViewObject ("TaskViewParTaskTypeIdEx1");
  	String userId = getBindValue (vo, "BindProcessedByUserId") m:System.NET.SocketAddress.ToString ();
  	Output string;
  	If (createdById.trim () .equals (userId)) {}
  	output = "LOV_TaskStateIdFkOwner";
  	} else
  	output = "LOV_TaskStateIdFkNotOwner";
  	return output;
  	}

  I've used this many fragments of jsff perspective.

  There are fragments where it works fine (but I still don't understand why the switch method is called 3 times)

  And there are fragments where it fails. When there are two lines with different LOV to show SelectOneChoice shows an incorrect value.

  I can see the newspaper that LOV switcher method is called 6 or more times and first 3 times it works with values previously selected line and next time, it runs with the current line.

  He result is SelectOneChoice sets the value of the line previously selected in the first round and goes the LOV index.

  I found in the < getViewPort > ADFc log < ControllerState > message: no port view found ID...

  Is the source of the problem and what is the solution?

  Thank you.

  After eliminating all the differences between 'good' and 'bad' fragments I found a problem in the fragments of masters who defined a real line of iterator.

  Define RangeSize = 10 (not 25) table completely setting to change this behavior in common sense.

  1. I have an attribute of code on the user interface of a view object.
  2. when I enter a value in the text field and tab from the text field, I have to run a query in the managed, get the code_description from the database and display in the code_description text field.
  
  These two steps work correctly with valuechangelistener implementation.
  
  3. If I return an incorrect value for the code then the database query returns no records and then, I display error message for the code field.
  
  Please could you suggest on the implementation of the validation logic. At the present time, I joined bean Validator support. In the validator method, I get the description of code and if it is null then I throw ValidatorException.
  
  Is it possible to attach the error message in the logic of valuechangelistener
  
  Thank you and best regards,

  Hello
  Your scenario is a little strange because you implement a lov with the scenario of the description of our self - most of the time that component with lov and an association to entity added to the view object to retrieve the description. This way you will have validation on the lov entered automatically by the ADF.

  If you insist on your solution, you can show your valueChangeListener FacesMessage. This message can be attached to the inputText component you are using.

   FacesMessage fm = new FacesMessage(FacesMessage.SEVERITY_ERROR, message, details);
   FacesContext.getCurrentInstance().addMessage(, fm);
