• Select list no display display value will return null instead

  I've been using selection for several of my applications list and something happens in this application that I can't identify. I have two select elements (with submit to point 3.2), Department and org (i.e., division). The user enters information about employees to the employee. If the Department is selected, the list of selection org is filled with only these associations related to the Department. Which works very well.
  
  The problem is...
  When information on the employees of the table is displayed (after it is registered, of course). the Department and org appear as "null", even if the line of database contains the correct data. It does not display the name of the Department and the division.
  
  Can someone please?

• How to fill in the right side of the shuttle with display/return values?

  Hello
  
  I know, the right way to fill in the right side of the shuttle's only:

  declare
       v_list     apex_application_global.vc_arr2;
  begin
       select profile_name return_value
         bulk     collect
         into     v_list
         from     user_profiles
        where     user_id = :p61_user_id;
  
       return (apex_util.table_to_string (v_list));
  end;

  It is comfortable for the user to see the name of the profile.
  However, I need a profile_id as return value, as I have on the left side of the shuttle.
  
  The left side of the shuttle is filled with a selection list with display/return values, as you know.
  I need both sides of the shuttle to return profile_id in order to create a merger.
  
  How is it possible to fill the right side of the shuttle with display/return values?

  Make a selection list on the left side of the shuttle to return profile_name as return value as well.
  In this way, the two parts of the shuttle will return the same value, which could be used as a State of fusion.

• Reset the value of the selection list

  APEX version: 4.2.2
  
  I'm fighting to implement a solution to reset the value of an element from the list of selection on a page in my application.
  
  I currently have about 4 pages in my application with a level of tabs with every page on its own tab.
  
  I have a report of Emp page that lists employees. The page contains an element of selection list for emp_no who submits the page when the value changes. The query for the list of selection queries the emp for name and emp_no table. It has:
  Display additional values: Yes
  Display Null values: Yes
  Display NULL value: all THE
  Return NULL value:
  (no value for the return NULL value)
  Page, in itself, works the way you want. During the first visit to the page, EVERYTHING is selected and the report shows all the EMOS. If I select a specific employee, the page refreshes with just this employee.
  
  On the Main page is another employee list report. The report has a link between the employee id column and the Emp report page. The link sets the value of Emp.emp_no to the value of Main.emp_no. It works very well so if I take emp hand 123, 123 shows Emp.emp_no and the report shows that retail for emp 123.
  
  The problem is when a specific employee has been selected previously from the homepage or the Emp page and I click on a tab to another page, say the status tab / page and then click on the tab of the page of the Emp. The current behavior of the page, is that it continues to show some used was previously selected regardless of how it has been set, either Emp or to the homepage page. I want to reset select Emp.emp_no ALL (or null) if I navigate to the page of the Emp to any other page except hand or Emp itself.
  
  I searched through the forums and tried to use processes at the level of the page and after region to reset the value of Emp.emp_no, but nothing has worked. I believe there is a 'simple' way to do it that doesn't require coding on each page to set Emp.emp_no on a null value before calling it.
  
  I would like ideas on solving this seemingly simple task that has managed to escape.
  
  Thanks in advance.

  Use a query in your link for filtering the selection list. Create a compuation on the definition page of the selection to NULL list if the request is NULL > PL/SQL Expression >: APPLICATION IS NULL. In this way, you can check the list of selection gets nulled while accessing the page normally.

• Not allowing a value for a selection in a Select list

  Version 4.1.1.00.23

  Hello

  I created a Select list to display projects within a Department (that we call groups).

  A group will have projects, however, more than one group may have a project with the same name.

  If my application for the display of the list select the data in a hierarchical format like this:

  Group 1

  Proj Grp 1

  Proj Grp 1

  Proj Grp 1

  Proj Grp 1

  proj Grp 3

  Group 2

  Proj Grp 1

  Proj Grp 1

  Proj Grp 2

  Proj Grp 2

  Group 3

  Proj Grp 1

  Proj Grp 2

  proj Grp 3

  What I'm looking for, it's to NOT allow 'Group' level to be selected in the list. Only allow the level of project to be selected values.

  The query is:

  WITH t
       AS (SELECT 'Group: ' || vg.group_name name
                 ,vg.group_id
                 ,NULL id
                 ,1 AS weight
           FROM   vertical_group vg
           WHERE (vg.group_id = :P100_GROUP OR :P100_GROUP = 0)
           UNION ALL

  SELECT name

  Can someone help me with this?

  Is there additional information that I can provide?

  HTML optgroup element is used for the structure select of the lists in this way. Select standard lists the APEX and LOVs do not have support for generating optgroup of the items in the lists of options, but point of plug-ins with this feature are available.

• The highlight in the selection list values

  I have a list of selection of a code that display additional values. Usually I would only code values where the obsolete_ind = "N" and limits the selection to these codes, but when a record is displayed with a code rendered obsolete once the record was initially created, I MUST allow display additional values. IIF, that I don't have, the first value in the list by default, and it seems that it is the current value, which is not true!
  So, I have 'show extra values', but I would like to avoid the registration of 'saved' by using the now obsolete value. Of course, a validation that will solve, but the user will not know who are the valid codes to select.
  Can specific values highlighted in red or something? If the tag selectlist < option value = "" > id has also been = "", a code for the dynamic action, but I do not see how to add this 'id' to the tag option. "
  Any suggestions?

  Some options that come to mind
  -use apex_item to build your selection list, the parameter cattributes allows you to easily add custom attributes to color some entries
  -Several times in the past, I've seen some old values of code marked with an asterisk, then users are educated to know that they are the older options and validation (browser or submit) it applied.
  -Having a display-only field that shows the current value and a selection list that offers only the current options

• Select the value of the text element based on the selection list

  Hello
  
  I have a selection list that displays a number of codes of a table, and I want to display the description of the code (from the same table) in a field of text next to it.
  
  The selection list works good based on an LOV, but I can't seem to find how to get the return value, so I can identify the correct description of the table to be displayed.

• Null value in the selection list

  I was wondering if there is a way to get a select list to return a value zero?
  
  I have a query with a condition like this where clause

  instr(upper("TYPE"),upper(nvl(:P3_TYPE,"TYPE"))) > 0 

  Where: P3_TYPE is a selection list. However, when it is null, no value no is returned in the report of sql - I guess that the nvl function is not picking up with the null value. I just that it displays all of the records when the value is zero in the list.
  
  Thanks in advance,
  Trent

  use

  instr(upper("TYPE"),upper(nvl(DECODE(:P3_TYPE,'null',NULL,:P3_TYPE),"TYPE"))) > 0
  

  When your selection list returns "null" for NULL values. Please note that select the return list value is a string that is not equivalent to PL/SQL NULL

• 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?

• Problems of selection list static apex

  I have a selection list (P147_EVENT_TYPE) with only two values, defined as:

  Static: Hurricane; HURRICANE, River; RIVER

  The selection list filter a report. The user selects 'River', they see all the events of the River in the report. The user selects "Hurricane", they see all the events of the River in the report.

  I wanted to make changes so that there would be a possibility to see "All events". Inside the element, so I changed:

  Display nulls-> Yes

  Null value display-> all Types of events

  Return NULL-> white left value

  The query of the report itself along the lines of:

  SELECT name, type

  Areas

  where ((P147_EVENT_TYPE = "Hurricane" or P147_EVENT_TYPE = "River")

  or P147_EVENT_TYPE is NULL)

  Normally coming to the page on the report, the selection list should display 'All Types of events' and the report is expected to be Hurricane events and river. However, when I get the report selection list (P147_EVENT_TYPE) is displayed for 'River '. It has three choices in there (River, hurricane and all Types of events), however, if I select "All Types of events" in the selection list, it is just for the river. Is it possible to change this? Can I not use a static selection list with a default value type? Any help on that would be great. Thanks in advance for your help.

  It looks like somehow the default value is used for 'River '. I'm trying my earlier suggestion and see what's the result. It must be fast to try it. You can also set up on apex.oracle.com so we can fix it.

• DA to select list does not work

  Hi friends,
  
  I have a two of my form fields.
  
  person ID < li >
  < li > manager name (selection list)
  
  I gave a value for the id of the person as '270' by default. So I need to write a dynamic action so that he'll be looking for the name of Manager according to the id of the person '270'.
  
  As my manager name is a type of list, select, I gave the following query in the definition of LOV from this point of
  

  select papf.full_name d, papf.person_id r
  from per_all_people_f papf,
       per_all_assignments_f paaf,
       per_all_people_f supf, hr_all_positions_f hapf, hr_all_organization_units haou
  where papf.business_group_id = 216  
  and papf.person_id = paaf.person_id and hapf.position_id=paaf.position_id and haou.organization_id=paaf.organization_id
  and  NVL(paaf.supervisor_id, papf.person_id) = supf.person_id
  and sysdate between papf.effective_start_date and papf.effective_end_date
  and sysdate between paaf.effective_start_date and paaf.effective_end_date
  and sysdate between supf.effective_start_date and supf.effective_end_date
  and sysdate between hapf.effective_start_date and hapf.effective_end_date
  and papf.person_type_id = 5145 
  order by 1   

  It comes from the DA, I wrote for the column id of person.
  
  For the real action, I gave as "Set value" and gave the following query
  

  select supf.full_name
  from per_all_people_f papf,
       per_all_assignments_f paaf,
       per_all_people_f supf, hr_all_positions_f hapf, hr_all_organization_units haou
  where papf.business_group_id = 216  
  and papf.person_id = paaf.person_id and hapf.position_id=paaf.position_id and haou.organization_id=paaf.organization_id
  and  NVL(paaf.supervisor_id, papf.person_id) = supf.person_id
  and sysdate between papf.effective_start_date and papf.effective_end_date
  and sysdate between paaf.effective_start_date and paaf.effective_end_date
  and sysdate between supf.effective_start_date and supf.effective_end_date
  and sysdate between hapf.effective_start_date and hapf.effective_end_date
  and papf.person_type_id = 5145 and papf.person_id = :P6_PERSON_ID

  Article submit page: P6_PERSON_ID
  
  Affected item: P6_MANAGER_NAME.
  
  Shortly after the loading of the page, the field of the crib should display the name of the Manager for the LOV '270' value that is in the element id of person. But it does not show the name in the selection list item.
  
  
  Suppose that, if the Manager's name is in "view only" means that it works, but if the manager name field is in LOV means, it does not fetch the value and it displays only the display null value in this area.
  
  I don't know why him DA does not work if the field is in LOV.
  
  Brgds,
  Mini

  Hey Mini,

  a page of type element "select list" always stores the return value (second column of your LOV) in the page element. So in your case, you actually rename the element of your page to P6_MANAGER_ID (to take into account that this is an ID) and change your 'Set Value' query for the papf.person_id

• Cascading selection lists - does not

  I'm trying to implement the Ajax solution cascading select list of Denes Kubicek.
  [http://apex.oracle.com/pls/otn/f?p=31517:119]
  But something is wrong with my configuration.
  
  I created all the pieces, but for some reason it is like the
  Attribute of the HTML form element defined on my point P3_emp_dept is not called.
  OnChange = "get_select_list_xml1 (This, 'P3_emp_name');
  
  The two elements of P3_emp_dept and P3_emp_name selection list are defined as "Select generic list".
  For the Source, I tried the two "Always" and the "only when... sucks.
  Source type is defined as the "column of the database" P3_emp_dept and P3_emp_name respectively.
  
  When you fill out a blank page after choosing the P3_emp_dept, the P3_emp_name
  selection list is empty.
  
  When you change an existing record, if a different value is chosen for P3_emp_dept,
  the selection list for P3_emp_name still shows in the former Department employees.
  
  Any ideas?
  Thank you, Sue

  Sue:

  The second parameter to the function 'get_select_list_xml1' must be the name of the selection list that displays the names of the employees.
  Modify the call to this function for the 'Exchange' event handler declared to the selection list.

  onchange="get_select_list_xml1(this,'P3_EMP_NAME');"
