• Two Select lists with Submit single page branching to different page each?

  Hi all
  
  I have a page (No. 1) with two 'select list with Submit"(A and B). This page contains also two branches defined. I want to realize that the first list selection with present (A) would always use the first branching (at page n ° 2) and the select list a second with the submit (B) would use the second fork (at page no. 3).
  
  How can I achieve this? Y at - it a tutorial describing lists of selection and the ramifications?
  
  Thank you for your time.
  
  Daniel

  When the selection list submits the page, the value of "motion" is the name of the selection list item. So all you need to do is add a condition to each Directorate-General: Request = Expression 1 and enter the name of the element (top) in the field of 1 the condition Expression.

• The hide/show button with the AJAX selection list

  I have the button named "QUERY" and AJAX list selection page #2 'ID'. When my selection list value is 100, I would like to display the button, otherwise hide the button. I checked the session values are defined correctly for the selection list when I change the value, but the following code in one of the messages in the forum does not work. is it different for elements of AJAX?
  
  Added the following code to select the list - onchange = "disble_enable_button (); »
  
  function disble_enable_button() {}
  If x$ ('P2_ID') .value = '100'

• Slight problem of AJAX selection list, I hope...

  I probably looked at all the examples that uses AJAX to fill selection lists that are out there and eventually got a job almost completely.
  
  In my application, I use a form on page 23 to create a folder and then also use a form on page 22 to update a record. Two of these pages, I have 2 selection lists that use AJAX to complete each other. On my page of form creation, these two select lists display properly and correctly submit a report page.
  
  Now, when I click on the document I just create the homepage, I get redirected to the update (page 22) page where I just submit all items are displayed correctly except the second selection list. The second selection list displays the correct list of the elements in the selection list, not the one I had just chosen. What is shown is the first option in the selection list, no matter what I had selected when I created the folder. Always the first option display anything in my code?

  Hello

  There are a number of issues here:

  1. remember that creation and editing features are on TWO different pages - when you refer to "the page is not save...". ' is in fact another page
  2. in the CHART table, you have an ID column AND a column RECNUM. You use the RECNUM column in the report link. In the CHART table, there are plenty of duplicates in the column RECNUM, which made it impossible for me to test - whenever I've created a new record that he got the same RECNUM value as an existing record, and I couldn't change then my new record as the process of "search...". ' incorrect 'more than one folder. You must use the ID column in the link, because it is unique
  3. on the selection of CAUSE list, you had a few items in quotes - I have no idea why. It was actually a good deal to do for your original problem. During the construction of the selection list, the value of the CASE is used as the VALUE attribute on the OPTION tag by enclosing it in quotes. What were you end up with is: < OPTION VALUE = '"sometext" ' > 'etc' < / OPTION >. The VALUE is, therefore, ""-an empty string. I removed the quotes from the data
  4. more importantly, as the CAUSE table made a unique ID column, this should be used as a return value for the list and therefore, the value stored on the CARD table. If you do this, you use the quotation marks if they are in some cases

• Fill in the select list with two different queries depending on the user's group

  Hello

Basically each user sees only the projects they are responsible - that works fine. But I want all the people of the admin group to see all the projects - how can I do this?

• 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?

• Cascading - HELP selection lists

  I still missed something in the samples I've seen on the internet at cascading selection lists
  I just need a selection list to determine the choice of another selection list, use simple terms.
  Thanks for your help. Please need as soon as possible.

  Hello

  OK - first of all you must have an item hidden on page 2 that will receive the country code (I'll stick with my example, if that's ok)-say P2_COUNTRY_CODE.

  Now create two selection lists - say P2_STATE_CODE and P2_CITY_CODE.

  It helps if you check that the P2_STATE_CODE list is defined with a default value to ensure that the list can be filtered properly. Create a calculation, to run in the point of process "Before Header" and the conditional on P2_STATE_CODE is null (Type of Condition: the point in 1 Expression is NULL;) Expression 1: P2_STATE_CODE). The value of a "static allocation" of something that will not appear in the list (for example, ZZ for strings) or - 1 for numerical values. You can do this on the list of cities as well if you wish. The two lists must be defined to display null values and have something like - Select - like display null text.

  Your list of States should be created as a Select list with Submit with a list of values based on a SQL statement:

  SELECT STATE_NAME d, STATE_CODE r FROM STATES WHERE COUNTRY_CODE = :P2_COUNTRY_CODE
  

  Your list of cities is a list of select normal with a list of values based on a SQL statement:

  SELECT CITY_NAME d, CITY_CODE r FROM CITIES
  WHERE COUNTRY_CODE = :P2_COUNTRY_CODE
  AND (:P2_STATE_CODE = 'ZZ' OR STATE_CODE = :P2_STATE_CODE)
  

  Now, when the user selects a country from page 1, the country code is spent in P2_COUNTRY_CODE before the loading of page 2. The default values for P2_STATE_CODE and P2_CITY_CODE are defined and the lists are generated - cities list will display all cities for the country selected as the list of States shows only the default value of ZZ and cela "corresponds to" all cities of the country. Then, when the user selects an item in the list of the States, the page is sent and the value of P2_STATE_CODE is updated in the session. As the list of cities is based on this value, when the page is reloaded, it will be updated to filter based on the P2_COUNTRY_CODE and P2_STATE_CODE values.

  The only thing you need to ensure is that P2_STATE_CODE and P2_CITY_CODE are deleted from the cache when you have more page - you can do in the branch back to page 1.

• Select the list with the list of dynamic values with more than 4000 tank of query

  Hello
  
  I have no application where users can store SQL queries in a CLOB column. This query is then used to populate the list, select a dynamic element through LOV. Following the code returns the query for dynamic LOV used to populate the select list. It works fine except when the length of the lv_sqlStatement becomes more than 4000 characters. Then application crashes with "ORA-06502: PL/SQL: digital or value error: character string buffer too small" when Select the list item rendering.
  
  Any ideas how to get around this problem? Any help is appreciated. Do not say to them to write shorter than 4000 queries because I can't (it's operational requirements).
  
  DECLARE
  lv_sqlStatement end_user_set.sql_statement%type;
  BEGIN
  lv_sqlStatement: =: P2_SQL_STATEMENT;
  return ' select the label, value of (' | lv_sql_statement | t ')
  To_char (t.value) if not in (select value from end_user_set_member eusm)
  where eusm. EUSRSET_ID = ' | : P2_EUSRSET_ID | ')';
  END;

  I just blogged about this problem and posted a solution. See this announcement:

• Help with selection lists in the classic report

  Hello
  
  I work with APEX 4.1. Oracle 11.
  
  I have a simple and classic report with 4 columns (username, role, reading, updating). The columns of the reading and the update are select list with values of 'Yes', 'no '.
  
  Report looks like this:
  
  User role name read the update
  JSmith Admin Yes Yes
  LJones Dev yes no
  
  
  My requirement is that when the user selects Yes the update select list, the value of the associated column in the reading should change Yes as well for this particular user name. Change must occur after Yes is selected in the list select update.
  
  Im not very strong with javascript, but for testing purposes I applied: onchange = "alert ('hi'); "in the update column. When I make a change to the update select list, the alert returns to its position.
  
  Can anyone suggest how I can implement the change to the value of associated reading of Yes if the selected update value is Yes, for this particular line.
  
  Thank you
  Laura

• 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

• Select list type delay problem

  I have a Select list with a couple of hundred values produced, in alphabetical order. The first characters of each value in the list is an identification code. In our society, that we know and make reference to our products by their identification codes, and we know them quite intimately. So instead of scrolling to find the ID that we want, we will often simply press the drop down arrow and start typing the identification of interest code, and the advance list automatically to the appropriate location.
  
  So let's say our identification code is CBX197. I hit the drop-down arrow for the field and start typing: C B X 1 and then I pause briefly after typing these four characters (somewhere between 1/2 and 1 second). At this time, these previous characters I typed are "forgotten", so that when I hit '9', hoping to jump down in the section CBX19 of the values, instead it jumps to the first code ID that begins with "9", as if I had never typed the first four characters at all.
  
  So the question is: that that the amount of time that typed characters are held in the drop-down list of controls buffering before being thrown out and is this amount of time something that we can control in Apex? I would like to be able to specify that the buffer is valid for x number of seconds.
  
  Maybe it's just a built-in feature of drop-down lists in general, and there is nothing that can be done about it. But I thought I'd ask anyway.

  In my view, it is HTML implementation, could not see a way to change behavior at the Apex.

  My suggestion to approach, especially due to the high number of options in the list, would be to set up a "list of AutoComplete" (Ajax based), as this demo:

• report of initialization does not not account selection list values

  Hello
  I have a problem to understand the way in which apex treats the sequence of events.
  
  I have a little select lists and checkboxes, which stores the settings for a report) the sql is issued by a plsql stored procedure).
  The items in the lists change according to different users, and values from LOV (with sql). A go button to refresh the report if you change the settings.
  
  Although where the view, the report seems to be after the selection lists, the first time the report not displayed with the settings selected in the lists (the first elements), but rather the default values... even if they do not exist in the current list.
  When you press the Go button it appears correctly.
  
  I also tried to put the report with the conditional formatting, with a request for status = expr 1 (setting like name th button expr1 go)... but the report would never display.
  
  I'm sure there must be a simple explanation... but I can ' t find.
  
  Thank you very much for your help.
  
  See you soon,.
  Boris

  Boris,

  The default was just an example, you can use the code you like in the query to make sure by default to the correct setting for the user. The point is that you (or rather business case) dictate how this default view should look like.

  You will need to fill in a few gaps for us here and tell us how each case should be handled (don't forget, we don't know anything about your precise needs other than that tell us;).

  John.
