No errors, where should blank page, I start?

I use JDeveloper/ADF 11.1.2.3.  I have a bounded task flows with fragment of a page in it.  I have a page that shows the workflow in a region.  I run the page of JDeveloper.  The browser displays a blank screen - nothing on the screen, not even the header and footer of the page template.  The log shows no errors.  I tried to run in debug mode, but I don't know what to look for or where to put breakpoints.

No idea where to start looking for the problem?  Curiously, this page fragment used to work fine - but I tried to revert to a version that worked and still have the problem.

Well, I just thought of it - the fragment needs to support a bean, and I did rebuild the workflow and I forgot to put the bean support in the reconstructed stream of the task.  BUT - it is such a blatant mistake that I wonder WHY no error appeared in the newspaper saying something like "can't find bean named nomBean."

  • New cartridge HP 1320, installed, print without error messages and blank pages.

    HP laserjet 1320 running Windows 7 a new cartridge installed. About 20 pages have been printed perfectly well use few months. A day after the image were printed and the printer was arrested after the execution of the work; then, when the printer was turned on to the different print document, it has started printing blank pages without error since the same test page.  

    The Q5949XC cartridge was removed and turned to redistribute the toner in addition to recycle power but the problem persists.

    Please notify.

    Thank you.

    Try to print a test page for the device control panel & see the result.

    If internal printer test pages doesn't have an image printed on (blank page), try to replace (if available) by another toner cartridge or toner cartrdige tested with another printer of the work.  This is to confirm if the fault is with the toner cart. or with the printer hardware.

    If the fault is with the printer hardware, then you may have to contact HP technical support & have the product hardware identified & solved problem.

  • 6500 not print, ejecting just blank pages

    The 6500 it's print-no errors, but only blank pages come out.  Watch print preview also just a blank page.  All inks are full, then, really, don't think it's printer since preview before print empty watch.  Any ideas?

    Experimentation-changed (grey print) black to print all colors and pages came out with just the part of printed color, so obviously the question is the black ink cartridge, but preview how print also shows it blank if only the black ink used?  I tried 3 different applications.

    The 6500 is not printing in black ink and it has no alignment of the printhead several times.  There are no errors.  I watched a lot of suggestions on different forums and none seemed to work for everyone.

    After much experimenting, I'm not sure of what went around, or if it is a combo of what I tried, but it finally works.

    Here's what I did:

    -wind cleaned on black ink cartridge.  The State of the computer ink isn't the real situation; need to go to the printer printer status report, and mine showed the black cartridge empty, even if it was new and full.  I guess this caused ink status report print preview to display a blank page to print.

    -removed all cartridges and then went out the door-cartridge (right lever) and cleaned all the goop and ink variances using water and a soft cloth

    -clean all the points of connection to the black ink cartridge

    -still didn't work so partial reset (shot taken and shut off the power and then after 20 seconds, holding the key # and 3 keys on the printer and no power to the top.)  Still no go; always attack has no alignment; test pages would print color only

    d ' ran computer print head clean utility and after that, chose the command 'second clean print head ".

    - AND IT WORKED. !!!

    I used about a quarter of the ink in the cartridges of color do all the tests, etc.

    Good luck to all.

  • "I update firefox from 7 to 8 and now when I run firefox every time it opens the page 'do start with firefox', in options I select the option ' display a blank page" How can I solve this problem?

    I update firefox from version 7 to version 8, now when I run firefox every time it itself open the Web "to start with firefox", in firefox options I select the "show a blank page" but his does not work. I use firefox on windows XP - SP2.

    Try to restart Firefox, the time of a page (s) after the beginning of a new version should disappear. In fact this last time with 8.0 they did not come to the top for me.

    If it works then raise Subject: config and insert the url of the page into the filter. Right-click on anything that appears and use "Reset".

  • Where should I start simulation?

    Good day guys.

    I am Hari and I'm in my last year of biomedical engineering.

    I started my project in the field of rehabilitation (wheelchair).

    I think the production of simulation for my project...

    Can someone help me where should I start? And what are the things I should be aware off the coast?

    Thank you.

    Hello Harry

    Don't know what you mean by output of simulation and what hardware/software architecture and software you are using for your project.

    Usually you will use the compactrio hardware and write the FPGA VI and RT VI and also Windows vi if you want a user interface to monitor the status of the flags temporarily or send a few entries in RT VI. If this is the first thing to think about, and there is a lot of work to get a good system for such a request so started to work hard now, I'll propose.

    It is possible to test your written FPGA vi once in simulation mode by running the FPGA vi on computer simulation. This method determines only if there are no errors in the code and I want to save me time taken by FPGA to compile the code. You don't use it to simulate inputs and outputs on your hardware. To perform tests on your platform of rio, for example, features "will I get results if the input is x? You can use EITHER distributed Manager after you have written your FPGA code and compiled. There are good tutorials on the Web site OR distributed Manager OR.

    There are also third-party tools used to simulate and perform the simulation co precise Cycle using MentorGraphics ModelSim simulation package but you know VHDL for this. You don't really need it if you want to do a project.

    NEITHER really supports students working on projects. Your best bet is to give a call to OR and tell them you want to do this project using materials and you are thinking of rio platform. The sales engineer in your area can visit you and guide you through all the steps, and you may be lucky to get free training on the course OR FPGA and real-time application of OR.

  • Cannot configure FF to start with a blank page from today - now starts always with previous session

    I have the Options set to always open with a blank page and until today, which has always worked. But today it always opens with the tabs from the previous session. I certainly do not want. I've upgraded to version 38.0 but this made no difference.

    You can check if you have a user.js file in the Firefox profile folder that affects the pref browser.sessionstore.resume_session_once true value.

    You can use this button to go to the Firefox profile folder currently in use:

    Windows hides certain default file extensions.
    Among them are .html, .ini and .js, .txt, so you can see only file name without the file extension.
    You can see the type of actual file (file extension) in the properties of the file via the context menu in Windows Explorer.

    The user.js file is present than if you or another software has created this file and normally it wouldn't be here.

    You can check its contents with a text editor (right click: 'Open with'; do not double-click).
    The user.js file is read whenever Firefox is started and initializes the preferences to the specified value in this file, so the preferences set via user.js can be changed temporarily for the current session.

    You can remove the user.js file if you do not create this file yourself.

  • After installation or upgrade to Firefox 31, starting Firefox does not display the home page, personalize displays a blank page and the radio button does not work

    I am the admin of Windows for a University Department and install PC with Firefox all the time. This problem does not occur with every PC I would maintain, only a selection bit (model different laptops with Windows and update 1 8.1.) Until today, it has happened with the new user (with admin rights) accounts that I place on laptops for our staff. Today, this happened with the account administrator while setting up a new laptop. In all cases so far, I have install Windows from a registered image that was created by using sysprep.

    I tried many suggestions to reset Firefox, removing the profile of Firefox users, removing the Windows profile users, uninstalling/reinstalling Firefox, uninstall/reinstall of Firefox and the latest Java, but nothing helped. After uninstalling, I run an application to delete the caches and temporary files and even remove manually the keys to register HKLM\SOFTWARE\Mozilla and HKCU\SOFTWARE\Mozilla. I restart and make sure that the installation folder is deleted after uninstalling.

    Results are the same: after installing Firefox 31, the initial settings for migration, IE or Chrome pop up and after having clicked on the button finish, Firefox starts but does not display the home page of the new user, only a blank page. By clicking on the Options (3 bars) button does nothing. Right click in the appropriate box, the shortcut menu appears, so I can choose to customize, but which opens another tab with subject: Customize the URL and the page is blank. In the right click context menu, I can activate the menu bar and get options from that.

    My last attempt helped a little. I uninstalled Firefox 31, cleaned, removed the profile user Firefox, rebooted and then installed Firefox 30. Initial start-up runs and tells me that I'm not up-to-date and the works of button Options. But I can't always customize.

    Then I upgraded to Firefox 31, but then it's back to no start page, no options button and no customization. I can go down to 30 and get customize practically works again.

    Addon only is for McAfee Scriptscan to Firefox 15.1.0, just after installation is disabled.

    Any help would be appreciated. Thank you.
