Select list not used in graphic Flash

I have a page that contains a Select based on a list Flash chart. I want the table to take the default value of the selection on the first visit. However, when a user visits the page first, the array is empty (no data found). Looking at the session variables, they are zero. Once I have select a value in the select list and send the page, the issuance of securities in the session and the graph built as planned. How can I get the default selection list selected when a user first visits the page? Maybe it's a problem with how I build by default? Any suggestions would be helpful.

In your process to set a default value, check first if the element has the value null.
for example
If: P1_MY_SELECT is null then
: P1_MY_SELECT: = 'default ';
End;

  • selection list loading using the ondemand/ajax process data

    Guys,

    Ive has a selection list that has a query default LOV (select jobname d, jobid r of the work) but now iam trying to create application processes to pass new values LOV (like select ename d, empno from emp by 1 r) replacing the previous lov when a button is clicked

    any idea please?

    good idea to use the function in the pipeline, but I really want to use ondemand/ajax call here I don't mind spending extra energy so long as its feasible

    I never mentioned in pipeline functions.

    A dynamic LOV can be created as either a static SQL query:

    select ename l, empno v from emp order by 1
    

    or in the body of a function that returns a SQL query:

    declare
    
      lov_sql varchar2(4000);
    
    begin
    
      if :foo > :bar
      then
        lov_sql := 'select dname l, deptno v from dept order by 1'
      else
        lov_sql := 'select ename l, empno v from emp order by 1'
      end if;
    
      return lov_sql;
    
    end;
    

    This will allow you to create a dynamic data source for the LOV using some logic is required. LOV options can be modified using standard dynamic action of refreshment. There is no need to create an additional On demand process or write complex AJAX code. Use declarative when possible.

  • Editing cascading from the selection list - not refreshing during the loading?

    Hi all

    I have 2 lists of selection, the latter with an option cascading of LOV.

    Now, this works very well when you select an option in the list 1, list 2 fills correctly.

    Hello

    You have the following items in the pl/sql code of DA:

    begin
    select parent_id, child_id
     into :p1_parent, :p1_child
    from holder
    where parent_id = 1;
    end;
    

    You have the following in the query LOV's P1_CHILD:

    select col2 d, col1 r
    from child
    where col3 = :p1_parent
    

    P1_parent = 1, the LOV query returns 2 rows - DUNDEE and GLASGOW. The list of selection, therefore, cannot set a value. I changed the order of the day of the P1_CHILD page for a multiple-selection list and it works fine now.

  • Y510p is not using Nvidia graphics, only Intel HD4600?

    I just bought Lenovo Y510p with GT755M and HD4600 from Intel on board. They work in the Optimus technology.

    When I try to play Battlefield 3 or 4, this message appears: "device creation error DirectX. Your computer does not meet the minimum requirements to play this game. 'Intel HD 4600 Graphics does not support DirectX 10.0 required'
    When I play other games like the D3 or WoW I want computer performance is on low level (e.g. in WoW I max 25 frames per second in high circles), all games are fixed to prefer Nvidia graphics performance.

    The solution was to reinstall the Nvidia drivers to the previous version.

    Now I play all the games on ultra settings

    Looks like the new Nvidia drivers have problems with Optimus technology.

  • Clear the cache with graphic flash

    Hi all

    On a menu, I have a graphic flash with a link to goto page xx
    The url in the link have the clear cache attributes defined for the same page xx.

    on the same page of the menu, I also provide a list with an option for even goto page xx
    f? p = 103:2:815028013919804:NO:2:


    Now the question
    When you use the menu list of the cache is disabled
    When you use the graphic flash cache is not authorized!

    Some body have an idea how it works?

    Hugo Perfors

    I think that it is a problem of IE. Try to change the caching there options to see if it happens after that. I think that if you are using FF it won't happen.

  • HP Envy 15 laptop TS: PC uses Intel Graphics instead housed within NVidia Graphics

    Hello, everyone!

    My laptop is not using the graphics card Nividia (GT 740 M 2 GB DDR3), but my laptop uses Intel HD Graphics 4600?

    I do not understand why my laptop shows two maps, when I play my games, my PC automatically puts the card for better performance?

    I think that my PC is configured to always use the Intel chip.

    Any help would be helpful at this stage!

    Thanks, Justin

    Hello

    It will automatically switch to the NVIDIA card. If you wish, you can use NVIDIA Control Center to spend yourself:

    1. Right-click any space on the desktop,

  • Invalid results based on the select list

    Hello
    I've set up 4 LOVs cascading in a test application. They fill each value based on the value of the parent cascading with success. My example is based on the query Ajax Denes Kubicek - Section III - for example - http://apex.oracle.com/pls/otn/f?p=31517:135:1771969688591802:NO. But I use 4 Cascading Select list not 4 text fields. My problem is that I am not able to scroll through records using the previous and next unless I select all 4 list selection of waterfall to fill the data in the record. I would like to be able to select the 1st list select then click on the search button to fill in the data of the registration for the selected value. Then use the previous and next to scroll through the data in the record. This code allows selection of cascade 4 list to keep focus when the key search selected. But the correct data are not returned if I only select 1 list select value and then click on the search button.
    //  alert('TagName=' + l_El.tagName + ' id=' + l_El.id)
                    if(l_El.tagName == 'INPUT' || l_El.tagName == 'SELECT') {

    Hi Charles,

    OK - it works now.

    I made a few changes here and there. Basically, I defined by default for four '-1' lists and accounted for this through the page and processes. You had the wrong name for the last item in your function onLoad(), so I've changed that. Also notes that the question of the "closing date" must be formatted with a date MM/DD/YYYY formats to ensure that these are properly (the date of default real format came in the form DD-MON-AA, so you would have questions there if you don't stick to a single format). For each item, you can choose another value by default if it makes more sense for you, but you go through every place where the list is mentioned/used for updating the-1 for her to this new value.

    The processes themselves also tried to update the four lists as you go through the records. As the lists would not necessarily have all the values on them (you can click on search without making any selection, for example), I disabled these bits. However, you you should consider adding to the class section of THS page as new, so that the user can view all the information. The alternative would be to have all the lists display all the values unless otherwise filtered by their parent list - always feasible, but may be confused?

  • 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

  • Tabular returns lines based on the selection list

    Howdy-

    An element of the selection list is used to select a job title.

    The tabular presentation returns lines of documents to be considered annually by the title of the post.

    A single column in a tabular form (the number of the document) is defined as a link so that the user can open and read the document.

    It works beautifully.

    But...

    Some job titles return a row of five documents, still others return more than a hundred, so when paging is used to move to the next set of lines in tabular form, updates the selection list and the selection is lost.  I have the Page Action selection list element when the modified value to Redirect and set the value, but the Type of Source is static that may be my problem.

    How can I use pagination while maintaining the value of the selection list?

    Thanks in advance.
