Select the list when the button display problem in Oracle Apex

Hello world

I use a button that displays a selection list box (contains two values) click on...

Whenever the button is touched for the first time, the selection list box does not appear properly... the list box is displayed in a smaller size if the values it is not visible...
However it appears correctly when I hit the button for the second time... its strange...

Help, please!

Kind regards

There are two options. One is to create a Page process that fires before header or after and sets the value of the element. This method works when the value is independent of the other page elements. If the value is dependent on other page items, you can set all at once in the same process.

Example:

declare
  var_field1   VARCHAR2(40);
begin
  var_field1  := :APP_USER;
  :PX_USERNAME  := var_field1;
  select COUNT(row_id) into :PX_USER_COUNT from users;
end;

This example illustrates two ways to define the elements of the page: one using another variable and the other as a result of a pass-through select query. You can also use the function calls, the application variables and more.

  • By selecting the buttons "through" other objects

    This makes me crazy... especially because I'm sure it'll turn out to be something incredibly simple...

    I created a few 'pop ups' using a smartshape, legend text, an image and a button and them grouped.  The groups are hidden when the entrance to the slide, they are displayed by selecting the corresponding button on the page, and are hidden by the button in the group.

    The problem is that when I have these groups 'show' on the page that I have them set up so that they cover the buttons on the page... so the learner needs re - hide the group before showing another.  But it seems that when I try to select the button within the group to hide this group, instead it is by selecting the button in the same place, but 'below' of the group.  I checked all my orders, three times, and all the button functions are correctly configured.  In addition, groups are placed above the buttons of the page on the timeline.

    I've only tested using the option "Preview"... I have not published to see if the same thing happens in the final product.

    Any ideas on what I'm missing?

    Thank you.

    Never have two interactive objects in the same place at the same time is

    my bike. At least, you must disable the buttons under those that are

    active.

  • Click on the button "display remote content" content remote does not show. If I go back to e-mail even later "display remote content" is not on the page.

    The "issue" essentially lines the problem.
    No distance shows content when the user clicks on the button "view remote content. Once it has been clicked on a specific email, if I go back to the same email, the button "display remote content" is not on the e-mail page and no remote content shows again in the body of the email.
    I use an updated version (24.4.0) of Thunderbird.

    The problem is often caused by anti programs anti-virus and other security software blocking Thunderbird to get the remote images. The GET for images using a web port usually and some security software not see Thunderbird as a browser and block access.

  • Left mouse click selects the button but does not execute the action of the button (for example close)

    HI - this seems to be a problem with Windows rather than the mouse, so any help would be greatly appreciated!

    First of all - I have a trackball M570. Works fine connected to another Windows 7 machine.

    But on a single machine including windows 7... I can use the left click for most, but in some applications, when I click a button it not actually click the button. Yes, he selects the button but it does not perform the button action. I also see the issue in the boxes, I can't put a tick in the boxes. Or at least I just figured someway by combining fast random space bar presses and presses mouse, but it is obviously not right. Couldn't find anything useful in google, so I thought I would try here in hope!

    Thank you for the pointers !

    Cheers, Jim.

    HI - Finally - I found a solution.

    First of all - the following solution worked for me, but there are possible solutions mentioned on the thread I linked in my previous email.

    The mouse is a Logitech wireless, with the SetPoint software installed. I also had a Microsoft wired keyboard and just in case that was the problem, I replaced it and - YES! All good new - in fact explains some other issues, I was less concerned. The problem with the keyboard was somehow screwing of the mouse.

    Since then I have been reduced to a media volume on the keyboard button, no idea how to solve this problem, and the replacement keyboard was free, so just get rid of the old. Note: I could use the old keyboard when I downloaded the Microsoft Mouse and keyboard Center, installed and disabled the offending button.

    Thank you, maybe my solution might help some people out there.

  • The firefox button and the button display the panorama are two disappeared in FF4 RC1

    I upgraded to FF4 RC1 two days earlier and noticed that he was missing the button display the panorama and the firefox button, which is supposed to replace the file, edit, view menus etc. had not yet done. So basically, I'm still stuck with the buttons of the menu style FF3.

    If you hide the menu bar, you should get the Firefox button. That right-click on a toolbar and deselect the option "menu bar".

    For the Panorama button, right-click on a toolbar and then choose Customize to open the Customize toolbar window. Drag the "Groups of tabs" icon to the toolbar, then click done.

    Hello hpgirl18, try Firefox Safe Mode to see if the problem goes away. Safe mode is a troubleshooting mode, which disables most of the modules.

    (If you use it, switch to the default theme).

    • Under Windows, you can open Firefox 4.0 + in Safe Mode holding the key SHIFT key when you open the desktop Firefox or shortcut in the start menu.
    • Or open the Help menu and click on the restart with the disabled... modules menu item while Firefox is running.

    Once you get the pop-up, simply select "" boot mode safe. "

    If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to understand that one. To do this, please follow article Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems .

    To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.

  • Reactive Muse: by selecting the button home on small devices to move content to the left

    Hello

    After two successful fixed sites it's the first time I use sensitive Muse. I have the problem that small appliances on the content of my page document can be moved horizontally, although there is no hidden content on my canvas. It is extremely irritating when you use the home button (that means selecting the logo on the top which has an anchor to the departure site / homepage). Not only, everything is moving upward, as it should, but at the upper left corner...

    Here is the link to my test site on BusinessCatalyst: home

    No idea how to solve this will be much appreciated!

  • Update of the elements on the Page regarding filters in Oracle APEX interactive report

    I recently started using interactive reports in my Oracle APEX application. Previously, all pages in the classic application reports. The interactive report in my new page works fine, but now, I would like to add a summary box/table above the interactive report on the same page that displays values added some columns in the interactive report. In other words, if my interactive report displays 3 names of separate Manager, 2 separate offices and 5 different employees, my summary (box) will contain a line and three columns with numbers, 3, 2, and 5, respectively.

    So far, I did this job creating the box summed up as a classic report that account of the distinct values for each column in the same table that my interactive report pulls. The problem is when I try to filter my interactive report. Of course, the classic report is not updated based on the interactive report filters, but I don't know how I could link the two so that the classic report meets interactive report filters. From my research, there are ways to refer to the value in the search box of the interactive report using javascript/jquery. If possible, I would like to refer to the value of the filter of the interactive table with javascript or jquery to refresh the summary box whenever a new filter is applied. Does anyone know how to do this?

    Thanks, Patrick! I was always getting some of the old filters for a reason, but I was able to use the tables included in queries to retrieve my ID to report, that I used in the APEX_IR. Function GET_REPORT.

  • Progressively display areas in Oracle Apex 5.0 (universal theme)

    Hello, what I am trying to achieve:
    https://apex.oracle.com/pls/apex/f?p=63709:1:2676260562286:

    So basically I have 3 region on page load all regions must be hidden, after that the user click on the button (Let's Say ADD_REGION) first region will appear on new clicks of the user on the same button second region indicated even for the third.

    in the link above I created a region called JavaScript_Working in HTML.
    I want something even for areas of oracle apex.

    Tried:

    (1) based on the ID of a region I created a DA who will hide the region during the loading of the page, but after clicking on the button it does not return.

    (2) Css: inline Css section of a page where I had called Display: none with region Id prefix.

    (3) javascript: get Null drop back so this idea.

    Any advice will be good enough.

    Always:

    Identification information: new_b/new_b/new_b

    App: Apex_Community

    ID: 63709

    page: 1

    Thank you.

    This function added

    function check_then_show(p_region) {
    
        if ($(p_region).css('display') === 'none') { // if  hidden
          $(p_region).show(); //  show
          return true;
        }
        return false; // keep looking for next region
    
    }
    

    and this at the click of a button

    if (check_then_show('#region1')) {}
    else if (check_then_show('#region2')) {}
    else if (check_then_show('#region3')) {}
    

    That will keep test in the order provided.

    Looks like you were something already to help the regions of catalog, you would like to combine? It was just the first idea that worked

  • The buttons display based on users

    Hello

    I have 2 types of users using my request. They are admin and developers. They have different privileges. When logged on as Administrator , 2 buttons namely approve and reject must be visible. When you are logged as long as developers, only one button named forward must be visible. Please guide me to achieve.

    Buttons have Condition attributes and authorization scheme. You can use one of these two conditionally display a button.

    In your case, I'd both DEV and ADMIN authorisation schemes. Much easier to reuse in other situations.

    (You can actually create only the ADMINISTRATOR and approval {no ADMIN} allows to inform developers. This can lead to problems in the future when groups of users adding more)

  • ADF Mobile: contact is created on the device that, after the user selects the button AUTHORIZE

    My app allows users to quickly and easily add contacts on their IOS phone.  I need help capturing the "do not ALLOW" button click.

    Background:

    When you add a contact to the users device phoneGap prompts the user "Allow PAP to access Contacts?".  After that this alert is displayed, the user must select "Allow" or "Disallow".  Of course if the user selects "Allow" my code works perfectly.

    However, if the user selects "Do not allow" I'm not able to capture this selection and process accordingly.

    Here's the line of code that treats the newContact for this user to the application.

    Contact newContact = device.createContact (contact);

    where the 'contact' has been resolved with the user data

    You would offer your expert opinion on how to do it please?

    Hi Firefox

    I right click on the download to open it and the box "you have chosen to open" appears in the lower right of the screen with the "radio button", already selected for "open with...
    So far, all this is perfectly normal.
    However if I click on the "Browse" button to make a choice then the title at the top of the box, closing "Cross" and the "OK" button all gone gray and are unusable.
    In addition, all the page Firefox is frozen / crashed and cannot be closed.
    I have no other option but to reboot the PC.
    I tried various suggestions I found on your forums, including the removal of cookies, disable hardware acceleration, and I uninstalled and reinstalled Firefox 12.
    I looked at your "troubleshooting information" and it does not show a graphic driver problem. However, my driver is the latest driver nVidia for my GeForce FX5200 card and it worked fine with firefox 12.
