In cascade LOVs (APEX 4.1) problem, using in the report does not define values

Hello

I use APEX 4.1.0.00.32 and I have a simple report as

SQL :*

SELECT * in the region
Region WHERE the like '% "| P3_REGION | » %'
and country like "%" | P3_COUNTRY | » %'
and the city like '% "| P3_CITY | » %'

Elements:*.

P3_REGION:
Select a separate region as d, r of the region of the region

Display the Null value: YES
Value null, display value: - Select -
Return value of NULL: + 0 +.

P3_COUNTRY:
Select distinct country as d, r of the region of the country where region =: P3_REGION

Display the Null value: YES
Value null, display value: - Select -
Return value of NULL: + 0 +.
Cascading LOV Parent article (s): P3_REGION

P3_CITY:
+ select distinct city, city as the region r, whose country =: P3_COUNTRY

Display the Null value: YES
Value null, display value: - Select -
Return value of NULL: + 0 +.
Cascading LOV Parent article (s): P3_COUNTRY


The LOVs work very well and the correct values are displayed if cascade through them

So, I want to the last step to filter the report with the values that were selected in the lovs. And that I does not.
I tried to add a button with the SUBMISSION of the page. After choosing values in all the LOVs and by clicking on the button SUBMIT page supports, alle LOVs are disabled (with value - select-) and the report shows all lines.
I tried to change the "redirecting to Page 3" button and setting the values P3_REGION, P3_COUNTRY, P3_CITY P3_REGION., P3_COUNTRY. & P3_CITY. but without success.
I tried to use the 'Page Action time value' parameter to 'Validate' or 'redirect and set' for all the element LOVs or only the last element LOV, but then the cascade of the LOVs is not working properly and the report does not change.

I am confused as I Don t know what I can do so far. I think this should be a condition easy limit/filter the report with the values in the LOVs.
In addition, it should be possible to choose only the LOV region and then limit the report with this region (not select country and city)

Thanks in advance!

I had a problem similar to a previous version, fixed when I updated element Source value or Expression (the section of the Source) to himself.

I mean:
for the P3_REGION, defined as & P3_REGION element.
for the P3_COUNTRY, defined as & P3_COUNTRY element.
for the P3_CITY, defined as & P3_CITY element.

It will be useful.

  • APEX 5 modal page: CSS for the layout does not work

    Hi experts,

    I have problem with CSS tag in the pages of the dialog box modal.

  • I have a hp compaq dc5800, that is used. The pc does not recognize the network interface card.

    I reinstalled win xp pro. When finished and restared the nic card was recognized that even if the lights are on when I joined cable ethernet an atheist. I installed the drivers but nothing has worked. Why this is happening and what can do? Thanks in advance.

    You are the very welcome.

    You have the small factor form (SFF) or convertible minitower (CMT)?

    Electrical supplies and the form factor of the audio and video cards must be flat with low profile brackets if you have a LTS. Power supply power is also less than a SFF in a CMT.

    I have a dc7800 CMT. I installed a very nice video fanless AMD Radeon 6570 1 GB card in mine and I love it.

    I have installed a sound card, but I guess you could do it.

    I don't know how that everything affects the audio settings in the BIOS.

    Most video cards are the HDMI audio chips on board, and those disable the integrated audio system. He must therefore go back into the BIOS and enable the onboard audio setting.

    It's so everyone guess what happens when you add a new sound card. It neutralizes the again integrated audio system (which would be nice in this case), it neutralizes the HDMI audio (not a problem if you never Hang PC via an HDMI cable)?

    In any case, if you want a sound card, you can get a card PCI or PCIe one that there is a PCIe location in the dc7800.

    If you have a Mini PC, I would not recommend add both a video card and audio, because that can overload the 240W P/S.

  • Problem with drop-down list that prevents the use of the functions, will not go away.

    Hello

    I have Windows 7.  I could not afford MS Office, so I downloaded OpenOffice and, later, LibreOffice.  My problem is, when I open a document to write in a program, a drop-down list (formatting) is displayed.  It starts with "Default" at the top.  The box does not work, if I click on anything that it just flashes.  Or it will disappear.  I tried everything I can think of to get rid of him.  And, as long as it's here, I can't write to a document.  I can close, but only by closing the program.

    Is this problem only with free Office programs.  Sometimes when I am looking for a program in Windows 7, or if I'm looking for the Help menu in 7.

    I'm not very savvy computer.  If you would be interested to help me, thank you very much, but please don't expect me to know some thing on anything whatsoever.  I used to use the mode BACK back in the day, but the subterrain of computers is a subject that I've lost contact with long ago.

    You can also try to test with another Windows user, in case you have a corrupt user profile.

    If things were OK and then maybe a few days ago, System Restore is an option.

  • using firefox 24, yahoo toolbar disappears and the keyboard does not work on some websites

    We have installed firefox 24, yahoo toolbar sometimes disappears. On some web site when trying to enter a password, the keyboard does not work until you double click of the mouse on the registration form. This on two different systems of windows 7. Each thin seemed to work fine before the update prior to the installation of 24.

    Hello

    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.
    • On Mac, you can open Firefox 4.0 + in Safe Mode holding the key option key when starting Firefox.
    • Under Linux, you can open Firefox 4.0 + with leaving Firefox then go to your Terminal and running Safe Mode: firefox-safe-mode (you may need to specify the installation path of Firefox for example/usr/lib/firefox)
    • 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.

    When find you what is causing your problems, please let us know. It might help others who have the same problem.

    I hope this helps!

    You boot from the disk and choose "Try without Unbuntu and change to your computer"?. Honestly, it looks that you have installed. In addition, using raid with Windows Xp support?

    If you have chosen to 'Try' Unbuntu I recommend now you run chkdsk /r from the recovery console. The problem is not with the hard drive probably, but with the file system.

    Download WIndows Xp Recovery Console from HERE. Save the file to your desktop. You will need to burn the iso image to a blank cd using the same way you did to the image ISO of Unbuntu ImgBurn. Although the instructions below refer to a Windows disk, the disk from the Recovery Console that you create will do the same.

    1. Insert the Windows XP CD in your CD-ROM drive and restart your computer. If you are prompted, select any options needed to start (boot) on the CD.
      
    2. when the text portion of Setup begins, follow the prompts. Select the repair or recovery option by pressing R.
      
    3. If you have a dual-boot or multiboot system, select the installation that you want to access from the Recovery Console.
      
    4. When you are prompted, type the administrator password. If you have not set a password for the account admin simply press on enter
      
    5. at the command prompt, type chkdsk/r > press ENTER. (Note: there is a space between the slash and the letter k).
      
    6. at the end of the output of scan type > press ENTER.
      
    7 restart your computer.

  • Problem of USB ports: remove the material does not work. It works on different computers for the same USB devices

    Original title: problem of USB ports:

    I have a computer dell laptop inspiron d1420 provided with Windows vista and I have upgraded to Windows 7 ultimate, I noticed that when I plug in a USB mass storage, when I try to remove it, I don't get the safe delete the message and lately when I try to remove it, I keep getting the message He's busy and I can't remove it. I tried the same USB on another PC and I have no problem at all. I connected a printer, USB cable and wondows llok have not the driver or didn't install the printer, he left as a device not specified with the name of the printer, but I can't print. I tried with another PC that is also running Windows 7 ultimate and I have no problem, windows has installed the driver, because I used the same printer and the same cable. What is the problem with my USB 4 ports and how to fix?

    Hello

    When you get this message while trying to remove a USB, it's basically a lock for this USB device by some process running on the computer. If we know which process is this locking mechanism, we could also find which Service is associated with this problem in the computer.

    To check this, you can use a program called Process Explorer. You can download this program from the following link. Once downloaded, extract the contents of the zip downloaded to a folder on your desktop. Inside this folder, you will see a file by the name of procexp , which is the executable for Process Explorer. The download link is:

    http://TechNet.Microsoft.com/en-us/Sysinternals/bb896653

    First, plug the USB to one of the USB ports. Then, once you have the executable to Process Explorer, right-click on it and then click run as administrator. Please allow all guests UAC can occur. Once the Process Explorer is running, please follow these steps to search for processes using the USB at the moment:

    1. click on Searchand then click on manage to find them or DLL on the options menu at the top.

    2. then in the pop - up which will turn up next, type the drive letter for the USB drive connected to the computer (for example G: or H:) right now and click on Search.

    3. he should then display all instances of the process that is using this USB at the moment with the corresponding process ID (PID).

    Now, once you have the names of processes using the USB at this time, you can terminate them by clicking on them and then clicking on Manage close. Once this is done, you should be able to eject the USB safely.

    I would like to ask the names of processes lock the drive in your computer. This should give us an idea of what we might have to take the next.

    In addition, for the other issue that you mentioned, in which the computer does not automatically and correctly detects the printer when it is connected to the computer, I suggest you to check whether or not your computer Plug-and-Play service is set to automatic. Here's how you can do this:

    1. press the Windows and the R on your keyboard to get to the top of the run box.

    2. type Services.msc in the run box and press enter on the keyboard. Allow all UAC prompts that may coming up next.

    3. once it opens the window of the Services for you, scroll down to the Plug-and-Play service and double-click it.

    4. in the properties box that will come next, the Startup type should be set to Auto and the Status of the Service must be started. If this isn't the case, please put these values.

    5. click on apply then OK, close all windows in the computer and restart the computer once.

    Once these steps was performed, please check if the problem remains the same. We know the results.

    I hope that these steps raises you in the right direction in order to solve this problem. Don't answer if you still need assistance, we will be happy to be of assistance.
