Cascading LOV using Javascript

I have the following data
I have 4 potential values for the cascading_selectlist_item_2 .
MAN, ENR, PRE, NMAN.
All 4 should return data
MAN - 46
ENR - 44
PRE - 54
NMAN - 4
When I change the value of my parent cell to NMAN I get what I would suspect.
If I change it to any other value my Select List is BLANK
Not even the htp.prn('<option value="1">- All Values -</option>');
If I limit in my view(apexim.vw_hrw_lov_sel ) to only include less than 10 values child LOV will populate.
ANY IDEAS

Dan thank you for the response.
I dont have Firefox (dam coorporate policy)
I cannot recreate on the APEX SITE.
I realize that in some cases my Select list does return more than 10 Rows.
so the assumption a made in my first post is incorrect.
I think I need to do some more exploration I think that the problem may be data related
I FOUND IT there was a & in the data at the 10th record.

  • Cascading LOV used as part of  From ?

    Background - We are using views because we need to join tables from Oracle instances. We're running 4.1.0.00.32
    All my report forms start with a select list:
    e.g. Item
    P4_INST
    select INSITITUTE_NAME d, CODE r
    from CRIN_DWDB_INSITITUTE
    P4_INST returns one of the following:
    AM
    CF
    FA
    I want to create P4_SUBLIB which would use the selection from P4_INST in the From clause to submit one of the following:
    am_al_items
    cf_al_items
    fa_al_items

    Concatinating the code to the table name will definately not work. Can you please show us the ddl for the three tables and if there is a code column in these tables is the value the same as the prefix of the table? in other words for table am_al_hol_locn will the code column be set to AM? if that is the case then the following should work:

    where code = :P4_INST

  • Get('XML') doesn't work, but get() does in javascript - CASCADING LOVs

    I'm trying to get cascading LOVs working in Apex 3.1.0 in Oracle 11g. When I call get.get('XML') it returns null in firefox and empty string in IE6. If I change it to call get.get() then it returns the XML as a string into Javascript.
    The Application process is getting called in both scenarios as i've put PL/SQL logging to disk in order to prove it. The XML being returned is very basic so i'm sure it's not a problem with formatting. I'm not getting any exceptions thrown in javascript either.
    Is it possible to use get.get() and then convert the text into an XML object which is returned as per get.get('XML') which at least will allow me to get something working ?
    thanks

    &lt;div id="XMLOUTPUT" style="border:1px solid blue; width:200px; height:200px;"&gt;&lt;/div&gt;
    &lt;div id="XMLOUTPUT2" style="border:1px solid blue; width:200px; height:200px;"&gt;&lt;/div&gt;

    &lt;a href="javascript:getMyXML();"&gt;Click&lt;/a&gt;Click on Click at the bottom of the page. The first DIV gets the get.get('XML') object and the second one the get.get() and a popup message tells you how many "select" items are in the XML version.
    As far as I can see, this works fine.

  • How to use a cascading LOV as a Web Services Consumer?

    How to use a cascading LOV as a Web Services Consumer?
    We are trying to populate a prompt programmatically.
    Our program is a Web Services Consumer.
    As an example we use Island Resorts Marketing
    The cascading LOV for City is
    Country -> Region -> City
    The City object is key-aware to the customer table
    The query is
    Customer | Revenue
    (where) City = [prompt]
    In order to make the key-awareness work, we must select the value (rowIndex) from the LOV
    When we run our program below, the LOV for City is not populated, as expected since we must first select the Country, then the Region.
    The code snippet below shows that the LOV for Country is populated. We have no idea how to go from there.
    Any hint will be immensely appreciated.
    Let us know if anything is unclear in the code.

  • Cascading LOVs (APEX 4.1) problem, using in report does not set values

    Hi,
    i am using APEX 4.1.0.00.32 and i have a simple report as
    SQL:*
    SELECT * from region
    WHERE region like '%'||P3_REGION||'%'
    and country like '%'||P3_COUNTRY||'%'
    and city like '%'||P3_CITY||'%'
    Items:*
    P3_REGION:
    select distinct region as d, region as r from region
    Display Null value: YES
    Null display value: - select -
    Null return value: +0+
    P3_COUNTRY:
    select distinct country as d, country as r from region where region = :P3_REGION
    Display Null value: YES
    Null display value: - select -
    Null return value: +0+
    Cascading LOV Parent Item(s): P3_REGION
    P3_CITY:
    +select distinct city as d, city as r from region where country = :P3_COUNTRY
    Display Null value: YES
    Null display value: - select -
    Null return value: +0+
    Cascading LOV Parent Item(s): P3_COUNTRY
    The LOVs work fine and the correct values are displayed if cascading through them
    So in the last step i want to filter the report with the values that were selected in the lovs. And this i get not working.
    I tried to add a button with SUBMIT of the page. After choosing values in all LOVs and clicking the SUBMIT button the page submits, alle LOVs are cleared (with value - select -) and the report shows all rows.
    I tried to change the button to "redirect to Page 3" and setting the values P3_REGION, P3_COUNTRY, P3_CITY to &P3_REGION., &P3_COUNTRY., &P3_CITY. but without success.
    I tried to use the setting "Page Action when Value Changed" to "Submit" and/or "Redirect and set value" for all Item LOVs and/or only the last item LOV, but then the cascade of the LOVs does not work properly and the report does not change too.
    I am confused as i don´t know what i can do until now. I think this should be an easy requirement to limit/filter the report with values in the LOVs.
    Furthermore it should be possible to choose only the region LOV and then limit the report with that region (without choosing country and city)
    Thanks in advance!

    Hi Dan,
    thank you for your answer. I have the solution now from Kleber_M, this works.

    1. Use bind variables in my query. It would look something like:

    WHERE region LIKE '%'|| :P3_REGION ||'%'
    AND country LIKE '%'|| :P3_COUNTRY ||'%'
    AND city LIKE '%'|| :P3_CITY ||'%'
    This was only a mistake when writing the post, i forgot the colon. I use bind variables of course.
    2. Make sure you have a comma separated list of item names that the report depends on beneath the SQL Query where it says Page Items to Submit. This will make sure that the value of those items on the page are bound into session state prior to the query executing.I tried this, too, but without success...
    3. Use Dynamic Actions to perform the refresh action when any of the three items changes. This would be both more performant and a better experience for the end user than a full page refresh.How can i do this. This sounds good, because when refreshing the page often some items oder actions are done that i don´t want to.

  • Set Cascading LOV Item using Dynamic Action

    Hi all,
    I have the following page item:
    P1_USERNAME
    P1_COMPANY  (LOV)
    P1_DIVISION (LOV)
    P1_DEPT (LOV)
    Item P1_COMPANY, P1_DIVISION, and P1_DEPT are cascading LOV on my page.
    I also have a table that contains the user and his/her company, division, and department.
    So I have a dynamic action that when P1_USERNAME is entered. The dynamic action will pull the COMPANY, DIVISION, and DEPT information from the table and populate the page item accordingly.
    I got the dynamic action working, I can confirm this by checking the Session State of the items.
    BUT I cannot get the LOVs to display the selected value from the session state. They always reset back to "- Please Select -", which is my display value when NULL.
    For example:
    I have a record like in the table:
    Username :alex
    Company : Finance Inc.
    Division : Admin
    Dept : HR
    When I entered the username into P1_USERNAME, this is what I see in the screen.
    Username :alex
    Company : - Please Select -
    Division : - Please Select -
    Dept : - Please Select -
    While the session states of the items have been set correctly as per the record in the database.
    Has anyone experienced this before?
    I think it's because the parent LOV (company), reset the child LOVs (division and dept), when the dynamic action kicks in.
    Thanks.

    I've just taken a look at your sample page and don't think this issue is actually too complicated to solve. (Actually, it was I who was mucking around in page 1, sorry for that. I was looking at it and then had to go. Picked it up again later on and just made a copy this time)
    You change the employee. The dynamic action fires, executes plsql and sets the values in the company2/division2/dept2 fields
    Company 1 is a cascading lov. Empo has changed? Company refreshes. Cascading for division and dept as well.
    You can see this happening in sequence as well when looking at the page. Select emp, it'll hang for a second. You then get the select list refresh icons.
    The sequence in which this happens is of course a bit wrong. You set the values for the items on the client side first, but then their refresh is kicked in, and so the value setting is simply lost again.
    What makes this annoying is how P1_EMPNO is a cascading lov parent of P1_COMPANY. Changing P1_EMPNO will refresh the lovs beneath it. However, you can't simply set their values after you've retrieved the user's company/division/dept, because each lov is dependent on the one above it. Eg you change the employee. The company lov is refreshed. Because the it is refreshed, the division lov will refresh. Now you can set the value of the company lov, but not that of the division one. Why is this? The lov for division requires the value of company in the session state. If you'd set the value for company after it has finished refreshing, it will already be too late for division to pick up the value set. .
    I made a copy of your page to page 5, “tom”.
    The first I did was removing the cascade from the company lov. You don’t need this. There are simply no parent lovs for this lov, as is evident from the sql for it. The companies always remain the same companies even when you select another person; it is not dependent on another item for its values.
    Then the timing issues come in play, and with them there is also the issue of the session state.
    So now companies always show. You pick a user, it runs the PLSQL block and put values in the P5_xxx2 items. P5_COMPANY can be set now, and this is in the set value of the dynamic action. By not suppressing the change event, a refresh will be triggered on its cascading lov, P5_DIVISION.
    Refreshing P5_DIVISION will only get the new lov values (constrained within the chosen company) for this item though, and not set the value. We already have the values in P5_DIVISION2 however, and thus can use the “After Refresh” dynamic action on P5_DIVISION to do this. In short: company gets set, divisions refresh to show the correct divisions, and then the selected value is set. Again, by not suppressing the change event on this item the depending lov on DEPT will be refreshed.
    Then by using another “After Refresh” dynamic action on P5_DEPT we can set the selected value once more.
    Also important is that I changed P5_DIVISION to submit P5_COMPANY when it is refreshed, and P5_DIVISION when P5_DEPT is refreshed. This makes sure that the correct set of values is retrieved and probably why you were struggling aswell. After company has changed and division has refreshed, the value on division is set. But the correct divisions are shown only because the chosen company has been set in the session state.
    The same for division - dept. After the refresh of division, the chosen value for division is set. This change will trigger the refresh on dept, and because dept has the division in its page items to submit list, the correct values will be retrieved.
    Take note that the “debug items” are required in this solution though. Just set them as hidden and unprotect their value. Your goal should be to reduce the amount of roundtrips to the server. Why do a plsql (ajax) call just to retrieve a session state, when the value is already on the page and all in one action? Three hidden items is just so much easier than 3 extra ajax calls, the tradeoff is plenty.
    There is one more noteworthy point, and that is the fact that dept is being retrieved twice. That makes sense because of the cascading lovs. Initially company is changed, and this will refresh division and this in turn will trigger a refresh on dept. At this point the lov for dept will be empty, because division will be empty. Because we set the value of division again after it has refreshed, this will trigger a second refresh on dept, though now the correct list of values is retrieved because division has a value set. Not that big an issue, but good to point out. If you’d have another cascading lov beneath dept, it would refresh three times.

  • Apex 4.2.1 - mobile theme display bugs and Cascading LOV bug

    I've setup a test at http://apex.oracle.com/pls/apex/f?p=35331 - username/password is test/test
    Simple page to show some issues I'm running into. Wondering if work-arounds exist or if a patch would be available before we'd go live.
    First and second issue are the same I believe. So - a normal text box (label1) looks fine. But, Label2 is a Display only item and Label3 is a read-only select list item. As you can see - both of the values appear smack dab right beside the label and not in line with the other fields. It's totally ugly and not usable as is. I've tried to move this over, but the label goes with it. I can see no way of doing it, but wondering if there's some hack I can put in to solve it...
    The last issues is with a cascading LOV. Simple table setup. Static on the first, the second a simple query that filters on the first. If you set the select list to Value Required and not to display null values - then when you click on the Second List button - it just hangs. The page is unusable. I suspect this has to do with the null or something. But - doesn't appear to matter if anything is chosen. Note - if the list is large - which I think then uses a different UI control, this is fine. Only when one of the lists is small does the issue reproduce.
    Any workarounds or fixes? Any ideas?
    Thanks

    Hi,
    I would suggest to not mix different questions and a thread for each of them. Makes it easier for others to follow.
    About your problem with the cascading LOVs, it appears that this is/was a bug in jQuery Mobile which we use under the hood. I was able to reproduce the problem with APEX 4.2.1 using jQM 1.2.0, but was not able to reproduce it with APEX 5.0 which will use jQM 1.3.0RC1 or higher. The problem occurs if a select list is empty.
    There are different workarounds available:
    1) set the attribute "HTML Form Element Attributes" of P1_CLOV_2 to data-native-menu="false"or
    2) set the attribute "Display Null Value" of P1_CLOV_2 to Yes and "Null Display Value" to - select - (or something similar). The "Value Required" = Yes will still guarantee that a value has to be picked. Having the extra null entry will guarantee that the select list always contains an entry, that seems to workaround the bug in jQuery Mobile.
    I have filed bug 16355963 - jquery mobile: empty select list causes javascript error
    to track that this is definitely fixed in APEX 5.0.

  • Cascading LOV in a Tabular form

    Hi Guys,
    I have read numerous articles on the generation of cascading LOV's in a tabular form but havent been able to get it working
    I have created an example in my apex workspace at:
    http://apex.oracle.com/pls/apex/f?p=4000:1500
    workspace XXAPPS
    Username guest
    Password demo
    app no 17551
    Page 2
    In my test scenario, I have an emp table, dept table and an office table.
    Within my tabular form(based on the emp table), I have a deptno column and an office column.
    Depending on what the user selects in the deptno column, I would like the corresponding list of offices associated to that dept LOV to be returned in the offices LOV.
    The table structure is
    EMP
    EMPNO
    ENAME
    JOB
    MGR
    HIREDATE
    SAL
    COMM
    DEPTNO
    OFFICE_ID
    DEPT
    DEPTNO
    DNAME
    LOC
    OFFICE
    OFFICE_ID
    OFFICE_NAME
    DEPTNO
    When the user selects a deptno in the LOV I would like that to control the values that are returned in the office LOV.
    I have used Jari's blog post:
    http://dbswh.webhop.net/dbswh/f?p=BLOG:READ:0::::ARTICLE:2003800346210117
    but as you can see it isn't quite working in that the office LOV is not returning anything.
    I am pretty new new to JavaScript and jQuery so am no doubt doing something wrong as some of the steps are causing errors and are confusing me a bit e.g. step2 is causing the page to return blank (I have commented the code out in the example)
    Any help would be greatly appreciated.
    Thanks

    It seems to me that the on demand process is not being called because I changed the code to:
    DECLARE
    l_sql VARCHAR2(32700);
    BEGIN
    IF APEX_APPLICATION.G_x01 IS NOT NULL OR APEX_APPLICATION.G_x01 IS NULL
    THEN raise_application_error(-20001,'code gets here');
    l_sql := 'SELECT competency_id AS RET
    ,competency_description AS DIS
    FROM XXMEL_FOCUS_COMPETENTCIES
    WHERE competency_category_id = ' || APEX_APPLICATION.G_x01 || '
    ORDER BY competency_description
    APEX_UTIL.JSON_FROM_SQL(l_sql);
    ELSE
    HTP.prn('{"row":[]}');
    END IF;
    just to see if the code is getting to the process but the error message that I put in the PL/SQL is not firing.

  • Cascading LOV bug??

    Hi all...
    please help with this issue.
    Not sure whether it is a bug or browser issue.
    APEX: 4.1
    Browser: IE 7
    Database: 11g
    If i have a cascading lov, and if i have a some javascript
    under the HTML FORM ELEMENT ATTRIBUTES ""onchange="alert('hi');"""
    The on-change event is firing twice.
    why is it firing onchange twice?
    please check the following app.
    http://apex.oracle.com/pls/apex/f?p=41803:2
    select a dept, you will get 2 alert messages.
    Is there any fix for this?

    Hi Earl...
    Thanks for the reply.
    Yup..as you said , it seems it a browser issue (IE 7).
    Instead of using the onchange javascript .. i moved my javascript code to "dynamic action". It works fine now.
    Thanks for the reply.

  • New Plug-in item doesn't work as cascading lov

    I have just finished creating a new plug-in that is a searchable select list. I want the LOVs to be cascading. In other words if I have another item on the page I want to be able to specify in my plugin item that the parent LOV is that item. How do I make it work with the cascading LOVs. I am guessing that I have to add some code to my render function but I have no clue what and there are no examples of how to do this. I did find the following in the api documentation but I am not sure how to use it or whether it is what I am looking for
    apex.widget.initPageItem
    Here is a link to an example of my new plugin. There are 2 items on the page. Z is set to have X as its cascading LOV parent but it doesn't work and would like to know how to make it work. You can also download my plug-in from this page and try it yourself.
    http://apex.oracle.com/pls/apex/f?p=32395:3

    Hi,
    the "apex.widget.initPageItem" will not help you in your case, it's used to register callbacks for $s, $v, show, hide, ... if you have a more advanced item type. You can have a look at the "Star Rating" plug-in which implements several of these callbacks.
    For adding cascading LOV support, please have a look at our own select list implementation in /i/javascript/uncompressed/apex_widget_4_0.js
    Search for
    apex.widget.selectList = function(pSelector, pOptions) {to get a blue print implementation for all the steps you have to add to your widget to add cascading LOV support.
    If you need further help, please let me know.

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

    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 reference 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 it possible ? IN CLASIC REPORT
    regards
    J :D

    Hi,
    >
    Is it possible ? IN CLASIC REPORT
    >
    Yes.
    It may a rather long thing to code, so be ready for it.
    Here is how:
    a. Use APEX_ITEM API in your Report Query. Make sure you specify the p_item_id parameter , using #ROWNUM#
    b. In the Parent LoV wrtie an onChange event trigger that fires a JavaScript function and pass the ID of the element .
    c. In this JavaScript function make an AJAX call to get the &lt;select&gt;...&lt;option...&gt;...&lt;/select&gt; , in short the complete HTML of the child LoV
    d. Push this HTML fragment into the Child Lov. You construct the ID of the target based on the ID of parent . E.g. f01_0001 to f02_0001.
    e. You may additional keep the child invisible or disabled initially, and then make it visible/enable it after it is populated.

  • Loading select list cascading lov

    I have three select list which each have a cascading parent lov, except the first one.
    1.- TOOL
    2.- CATEGORY
    2.- SUBCATEGORY
    Of those 3 select list items... what I save is the "return value" of the subcategory, which is an ID. So the problem appears when I try to edit the information after I save it. I tried to fetch the information in the "source type" area with a "sql return value" and also with the "default value" area, but it showed errors when I want to create a new record... So I'm wondering if I can bring the data with javascript or another manner... thanks
    regards, bernardo

    Hi Bernardo,
    the problem on your page 3 is that P3_CATEGORY isn't populated by a database column. That's why when you view an existing record it will not show anything. And because the value is NULL, your 3rd LOV (P3_CATEGORY_ID) will not find something because P3_CATEGORY is null or has an invalid value.
    You have two options:
    1) Add CATEGORY as database column to your PROBLEMS table or
    2) Use a computation or process to fetch the CATEGORY based on your sub category (P3_CATEGORY_ID) and populate P3_CATEGORY with that value. This computation/process has to fire after the "Fetch" process.
    See my example computation on page 3. In addition I have also set P3_TOOL as "Page Items to Submit" for LOV P3_CATEGORY_ID, because you should always specify all the columns which are used in the SQL statement in "Cascading LOV Parent Item(s)" or "Page Items to Submit".
    Hope that gives you a direction.

  • Cascade LOV in Apex 4.0

    Hello Apex Fun
    how can i make cascade list of value in Apex 4.0 ? i tried cascade which enabled in list of item properties but contain problems , please help me
    also when use that cascade the Arabic characters shown unclear ..
    Edited by: Moh Loay on Aug 24, 2010 2:46 PM

    Hi Moh Loay,
    I think you have to help me with that one, because I tried to reproduce that on apex.oracle.com and was not able to.
    1) I have created page http://apex.oracle.com/pls/apex/f?p=47158:22 which is a cascading LOV on the tables DEPARTMENTS and EMPLOYEES.
    2) For Department "Construction" I modified some of the employees to contain arabic and chinese characters
    3) I executed above page
    4) Changed the department to "Construction" which refreshed the employees select list
    5) Opened the Employees select list and everything shows up as I have entered it.
    Can you please verify with the above page that it looks good for you as well. Maybe it's an operating system/browser issue?
    If the above test case works for you, can you please create a test case with your failing data on apex.oracle.com so that I can have a look what's actually wrong. After you have done that, please provide the workspace, user and password so that I can access your application.
    Thanks

  • Cascading LoVs in Apex 4 based on a shuttle box

    I've set up cascading LoVs based on a shuttle box. When values are moved to the right-hand side of the shuttle box, the cascaded LoV items have their existing values cleared.
    Is this a bug? Is there a fix or a workaround?

    Hi again,
    I made an unconditional process, sequence 1, but the only
    thing working is the :P11_message is filled.
    BEGIN
    htp.prn('<script>alert(''Two is more then one'', Ok)</script>');
    htp.prn('<script language="JavaScript" type="text/javascript">alert(''TEST'')</script>');
    htp.p('<script>alert(''Two is more then one'', Ok)</script>');
    htp.p('<script language="JavaScript" type="text/javascript">alert(''TEST'')</script>');
    htp.p ('javascript:confirmDelete(htmldb_delete_message,''TEST'');');
    htp.prn ('javascript:confirmDelete(htmldb_delete_message,''TEST'');');
    htp.print ('javascript:confirmDelete(htmldb_delete_message,''TEST'');');
    htp.p('TEST');
    :P11_MESSAGE := 'TEST';
    end;
    Does any one have more suggestions.
