Button to navigate to another page does not not work properly all the time.

Hello

I'm just starting to explore the ADF, I use Jdeveloper 12.1.3.0.0 and integrated weblogic server that comes with the IDE.

I just created a simple application with a welcome page called Main.jsf and then 2 task bounded, streams called SearchStudentsFlow and Studenloansflow, each workflow has a jsf page. The home page has a single button that sends me to the first task flow, SearchStudentsFlow and I can see is the page in that workflow, AwardsSearch.jsf. Also in the AwardsSearch.jsf page I have a button that takes back me to the home page.

The first problem I have is that when I run the application starting at the home page button in the works of the great homepage the first time, the button send me to the AwardsSearch.jsf , but once I decide to go back to the homepage and then click on the button to go to the first task flow the button does nothing. This happens whenever I decide to return to the home page of any page in my project.

Also, I copied the entire previous project into a new project and I decided to use the ADF security infrastructure in this new project to create a log in page create users and give them different roles and levels of access.

I created some users who have access to all pages and all the streams, but when I run the application starts the login page and I login successfully and go to the home page, the button on the home page does not work.


I don't know why the button sometimes works, but not of others and also I do not know why when I use the login page, the button doesn't work. I don't know if these 2 problems are related or not.


This is my code in the homepage:

No idea why the button does not work correctly all the time?

Thanks in advance

Play well!

Now, we understand the problem and can help you solve it.

The problem is that you dropped the home page in the flow of student loan and place you thinking that you must return to the point of departure, the unlimited workflow. Actually, you don't the sheet flow loan student but simply see the homepage as part of the loan flow. The navigation rules remain those defined in the flow of student loan. Now, when you click on a button to jump to the stream of research, the target is undefined zed you simply stay on the same page, the home page.

To make your work use case, you set a return action in the flow of student loan that return to the caller, the flow of research which, in turn, will return to his name the workflow without terminals that hold the homepage. Remove the homepage of flow of charge to students. The case of navigation allows to navigate between the button and the new return action.

In the adf of flow research a wild-card rule that accesses the return operation sends the return flow to the home page. You must remove the sailing time pointing to research prices for the return operation because it can use the same rule of navigation of wild-card then. Then, you add a Bach student load flow navigation rule to the scholarship search page. This navigation is used for the return actionto_searchStudents.

  • Keyboard does not work properly on the Satellite P100-465

    Hello
    Toshiba P100-465, I bought last month and discovered that if you press any key sound (especially the SPACEBAR or enter) between the upper right, it does not work.
    I never saw such a problem anywhere in any laptop. Please confirm if this is the case with all or should I get my keyboard replaced.

    I read this forum for a long time and I have strength to find a lot of comments about it. Because of that I think he cannot be serious and I recommend you contact the partner of service authorized in your country.

    By the way if you press the keys correctly (around using the button) I see no problem there but service can check properly and if problem described is a problem with the hardware keyboard will be replaced free of charge.

    Bye and good luck!

  • My DVD player does not work and all the information I can find is "this device does not work correctly.

    Hi, I have Windows Vista and I use a computer laptop Dell studio. When I insert a disc into my CD/DVD drive, the drive spins and it looks like it is about to start and makes the same noise start several times and then just stops. My computer does not record that there is a disc there. If I double click on the DVD drive in 'My computer' it ejects my disc and says "insert the disc in drive E".

    I went on the 'repair' Microsoft online scanner and it told me that there is a problem, but he can fix it. In Device Manager, under CD/DVD-ROM readers I have Optiarc DVD +-RW AD - 7640S. Under device status - general - properties, it says "this device does not work correctly. He also says that I have the updated driver.

    I even uninstalled the driver as a last resort and then restarted my computer. It reinstalled the driver for me, but there was no change. Please help me!

    Hello

    Step 1: Please do all the same underneath if you did some before as is often total
    a process that solves the problem.

    Try this - Panel - Device Manager - CD/DVD - double click on the device - driver tab.
    Click on update drivers (this will probably do nothing) - RIGHT click ON the drive - uninstall.
    RESTART this will refresh the default driver stack. Even if the reader does not appear to continue
    below.

    Then, work your way through these - don't forget the drive might be bad, could be a coward
    cable or slight corrosion on the contacts (usually for a laptop) and other issues.

    Another possibility is that the cables are loose. Remove ALL power, then make sure that the cables in both
    ends. Remove and replace, do not just tight. For laptops, you can often clean power and
    contacts data with a pencil eraser.

    Some DVD players do not use the Windows default drivers so check with the manufacturer of system and
    manufacturer of device to see if there is a firmware or drivers for your drive if necessary.

    ===============================

    Step 2: You have disc problems as the CD/DVD is actually 4 discs in 1 case (CD & DVD
    Burn and CD and DVD read). So it is not unusual for 1 or 2 operational so that other parts
    do it right.

    Did you follow the Troubleshooting Guide for the reader who still does not work? There are some registry
    entries that do not fix the resolution of problems and those who "could" be the cause.

    Check with your Maker system and a device for the two possible firmware updates and the
    correct registry entries for your car.

    Here are the keys in my opinion, are those in question - for the CD/DVD drive of course subkeys as
    There will be other subkeys in these keys. Do not forget to ask involved specific keys as well as the

  • The top of my page does not work... the scroll bars, menu items, etc. The rest, about 2 inches from the top of the page, works very well.

    My side scroll bars do not work by clicking and dragging. They don't even show when I pass the cursor over them when they are at the top of the page. If I use the drop-down arrow at the bottom, they will come with one click at a time. Then, when they are a couple of inches high, I can choose them and they work fine. Is the same for the menu items at the TOP OF THE PAGE THE. Very frustrating. Even this page. If I scroll down too far and then try to type in this box (because it is now near the top of the page), nothing happens. I can also use the menu to make the bold or italic scrip... nothing on this bar at the top of this box... unless I scroll a couple of inches.

    This problem may be caused by the Yahoo! toolbar as scopes as well down and covers the top of the browser window, allowing links in this part of the screen not clickable.

    Start Firefox in Firefox to solve the issues in Safe Mode to check if one of the extensions or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > appearance/themes).

  • MagSafe adapter does not work after all the stuff that followed and merge card Ok?

    My Megasafe duck-head adapter used with a Macbook pro has stopped working while my back was turned!

    After trying all the controls and the actions described in the Apple support pages, it always dows not turn on or show any current to the small pins when checked with a multimeter.

    It is the death of the adapter or can it receive some kind of CPR?

    Chris.

    Hello!

    Could specify you which checks and actions you have done already?

    Your MacBook came with both a cable to connect to the power supply and plug adapter. Could you try both to see if it works? You might just have a broken charger.

    Please find instructions for that here: reset the management system (SCM) controller on your Mac - Apple Support

    If the battery is good behaviour

    1. Stop the Mac.
    2. Plug the MagSafe or USB - C adapter to a power source and to your Mac.
    3. Use the built-in keyboard, press shift-control-Option on the left side of the keyboard, then press the power button at the same time.
    4. All the keys to unlock, then press the power button to turn on your Mac

    If the battery is removable

    1. Stop the Mac.
    2. Unplug the MagSafe from Mac power adapter.
    3. Remove the battery. (Learn about removing the battery in the MacBook and MacBook Pro computers).
    4. Press and hold the power button for 5 seconds.
    5. Reconnect the battery and the MagSafe power adapter.
    6. Press the power button to turn on the Mac.

  • BlackBerry smartphone WiFi does not work most of the time

    It's like a broken record, I know, but my WiFi does not (most of the time).  It used to work well, but over time he works less and less! I use v5.0.0.979 (bundle 1607, the 5.1.0.177 platform and a Bold 9700)  I get the Green checkmarks for connections and WiFi and a white WiFi icon options.  If I try to use the browser of BalckBerry he started working in WiFi and I can see the blue WiFi on my router shows the data flow and then everything stops in for WiFi is concerned and after a period of time, it either expires or most likely to connect to the 3G network.  I used to (a 3 or 4 months) work just fine, but now very poor.  I tried another router and has the same problem.  I found no solution in the forum that makes my 9700 working properly.  If I connect to the weather apps Bug or Thomson Reuters. WiFi works great, load fast and I can see the data on my router blink indicating data streams, but whenever I use the BlackBerry browser, it won't work!  Crazy!

    I found the same thing as automatic power switch at night is interfering with connections no matter what I did. So I stopped using it and it works fine now manually turn it off. Not much extra actually works!

  • Satellite L500: WLan is de-energized and does not work most of the time

    Hi all, I have a satellite toshiba L500 running windows 7. iprimus have used wireless internet, no problem for a few weeks before that, used it via an ethernet cable as I didnth ave a wireless modem. my phone was off load the other night and went flat, next morning when I woke up and turned on, it wouldnrt to connect to internet after hours and hours of phone calls, iprimus and many resets winsock, ethernet and modem reset cable tests they tell me that the problem is in my laptop...

    So I rang toshiba... and they got forced to go in device drivers, cards, and then network and disable, actually uninstall the wireless drivers and then reinstall... and it worked... Finally... (forgot to add with the confusion iprimus someone had reset my passowrd and I had to configure to the laptop...)

    Anyway, after all of these calls, I did a full restore of the computer laptop, all deleted and reinstalled everything and then reinstall the modem. This time in the configuration of the modem, he told me the wireless network adapter was unplugged and let me only implemented via ethernet...

    now earlier today, I had the internet... but he dropped randomly... pages Web will go slow, sometimes it will reconnect, sometimes he used. now I thougbht could try and uninstall and reinstall the modem again, s soul mistake and this time, can not get the wireless at all.

    Ive google to see if others have had this problem... and seeing what others has written, I went into my battery settings and checked the WLAN will not in mode 'sleep', etc., and ive also checked everythings active. Ive no idea what do, or iprimus and Toshiba will give me answers, both companies are just to blame each other lol
    so I have
    It doesn't seem to be my laptop, as all the lights are on modem... and iprimus keep telling me its not record not not with them (disconnects) so my wireless. Although every time my laptop has left internet, so would my iphone of bfs were testing us and so did my other laptop which is partially drunk but couldn't normally always connect to the net... so as to tell me it is a problem of modem... Ive no idea what to do... and can not keep it via ethernet on the bench in the new House ive, as with 2 children less than 3 years moved in, is asking for trouble...

    someone at - it suggestions?
    Thanks in advance

    That s the best way to get rid of a client who has a problem, I know that those people who don't say, this is not my problem it problem computer laptop s ;)
    I think that the guys running out of ideas.

    However, first try an update of the WLan driver;
    NEST WLan driver can be downloaded here:
    http://APS2.toshiba-tro.de/WLAN/

    If new BIOS BIOS update would be available.
    You should also check the advanced settings of the wireless network card.
    To do this, go to Device Manager-> properties-> Advanced tab WLan card.

    Here you can choose some settings that would improve performance

    Good luck
