Why setValueExpression method for inputText not working properly

Hi,
JDev Ver : 11g 11.1.1.2.0
I have set value property of input text using setValueExpression method.
First time its working fine and setting value properly but when I set blank value using same setValueExpression method then input text automatically become read only.
I have not explicitly set read only true anywhere in my code.
For settting value I am using #{bindings.iProductName.inputValue} expression while resetting I am using #{''} value expression.
Is there any bug with this method or the I have done is wrong ?
Pls give your comment on this.
Thanks
regards,
devang

Hi,
You're doing something very wrong. If you want to reset the value, you reset the value, not modify the expression. So you need to call .setInputValue(null) on the ValueBinding. #{''} is a r-value, thus read-only.

  • Adobe Photoshop Elements 12: dropdown boxes for tools not working properly in Win 8.1

    Elements 12 system requirements are indicated up to Windows 8.  Does that mean it should also work on any Windows 8 upgrades, more specifically 8.1?  The drop-down boxes for the tools are not working properly in the program.  I've installed it, uninstalled it, and installed it again with the same results.  It worked fine on my old computer with Vista.

    Yes PSE12 will work on 8.1
    If problems persist try re-setting the prefs.
    Go to: Edit >> Preferences >> General (Photoshop Elements menu on Mac)
    Click the button Reset Preferences on next Launch

  • Why do some AVI formats not work properly with IMAQ?

    I've been trying to do work with manipulating AVI files in Labeled, but it seems that mine will not work. Whenever I try to load them I get the error:
    Error -1074396005 occurred at IMAQ AVI2 Close
    Possible reason(s):
    IMAQ Vision:  Invalid AVI session.
    What's strange is some AVI files will be read in fine. If anyone could explain why I'm seeing this error or how to convert my AVI files to the correct version I'd appreciate it. I've attached two files. The one labeled test will not work. The one labeled Balloon will.
    Solved!

    Hi,
    Does my code work fine? I attache the vi as well. I modify my code that is very similar with yours, but it is working fine as well. I put here for your reference. 
    BTW, i can't open your code due to the PNG file without code. You can Save for Previous as 2010 Version, or Edit-->Create VI Snippet...  save as png file with code.

  • Why does my google toolbar not work properly with the new updates. It was such a convenience to use the old toolbar to go to places I had visited before. Now I cannot get those old addresses with anything but Firefox 3.62 or whatever.

    Why does Google Toolbar not work with the newer versions of Firefox.

    Google have stopped supporting Google Toolbar on the latest versions of Firefox. Apparently one of the reasons for this decision is that modern browsers already tend to support many of the functions that google toolbar provides.
    Firefox does allow you to specifically bookmark sites you have chosen, and also automatically remembers many of the sites you visit.

  • Property for fields not working properly.

    Hi
    I am doing some validation on tab strip.
    initially on some value my tab strip is coming,due to visibility binding property.
    now i am trying to do visibility binding on individual tabs of tab strip on user based,which is not working.
    is there any way to make it work out.
    my code:     
       call method wd_context->set_attribute
            EXPORTING
              name  = `PROP_CREDIT`    "Context attr name
              value = space.
    to hide a credit view, i had attached a attr to its transparent cont.,& have passed the value space to make it non visible.
    but it not working,i am doing this like enabled,visible on 3-4 tables,but noting happening.
    pls let me know how to make it work.

    HI Vipin,
    I have tested ouy this way...
    Ihave a TB with 3 tabs, Last tab has got One TC inside which there are 2 other TCs(TC2,3) with Input fields inside them.
    I bound the ENABLED property of TC2 to the ENABLE(wdy_boolean) property and coded in DOINIT of view.
    I didnt code it in modifyview.
    Its working fine for me..
    Please test it in some demo application you will get to know the errors.
    DATA lv_enable TYPE wd_this->element_context-enable.
    * get element via lead selection
      lo_el_context = wd_context->get_element( ).
    * @TODO handle not set lead selection
      IF lo_el_context IS INITIAL.
      ENDIF.
    * @TODO fill attribute
    lv_enable = abap_false.
    * set single attribute
      lo_el_context->set_attribute(
        name =  `ENABLE`
        value = lv_enable ).
    I guess, there is some thing going wrong  in MODIFYVIEW. for every event this gets triggered right.
    Now the TC2 got disabled also the Inoutfield inside it got disabled.

  • Why does 'check for updates' not work?

    Just curious why the updates do not work? Is it just easier to download the release2?

    Check for updates is intended for use after production when we might have small changes to 1-2 files. Our current releases have many changes to many files and might almost be as large as the download. Also, we are still making structural changes to the storage of the code (shifting around preferences, etc). For the Early Adopter Releases, we really want people to download and install in a clean directory. After production, we will support check for update.

  • "Email for Nokia" Not Working Properly after Firmw...

    The "Email for Nokia – 10 Accounts" also called Nokia Messaging does not work after firmware upgrade. 
    I upgraded my E63 firmware from 400.21.13 to 410.21.10 (the latest).   After upgrade, I installed the Email software, ver 9.07(2), from Ovi store.  The problem starts after I entered my email address and password.  The software imported the email account to the Communication --> Messaging  folder (where you used to read your text message). Before upgrading, the email software manages all my email accouts and synchronise up to 10 emails.  Now that nice email software and user friendly interface no longer show up.  Instead it uses that poor design Communication --> Messaging folder.  It only allows maximum 2 email acct. auto retrieval and NOT working with yahoo mail.  
    Please advise how can I get eh Nokia email works again.  thanks

    Very upset with Nokia's tech support service, taking so long not calling back after contacting them.  Finally I found a work around.  After reinstall the email software, setup a new email account never used with Nokia email before.  Then the software will setup correctly instead using the messaging folder.  This is a bug with the Nokia email software and the new firmware.    OR the Nokia email software is intended to do it that way because it's a trial version.  It just let you try it for the first time of installation. 

  • Why are my PalPal buttons not working properly after working fine for weeks?

    I have not touched the site till I heard there was a problem today. The dropdowns are not showing up.
    https://www.appne.net/events.html
    Sometimes if I hit refresh or republish the site, they show up again. then after testing to see if they work, they disappear again.
    I just upgraded to the April 2 release to see if it helps and it did not.
    I talked to paypal and tested the buttons on their testing website and they worked fine.
    I did not use the widget in Muse to create...I cut and paste the code from paypal.com button creator.
    Anyone else having the same issue?
    Please help if so. Thank you!

  • Why does my mac keyboard not work properly and is to do with the extra RAM?

    Like someone else who has posted on this forum I have a problem with my Apple Pro Keyboard (usb, white, english) The keyboard has developed a fault which has resulted in the tab, caps lock and some other keys near them refusing to work. The caps lock light illuminates at startup but thats about it.
    I've run various checks, reset my logic board, unplugged all the cables I can and still nothing. I recently installed two 512mb memory things boosting the machine's memory to 1.5gb. I have since done a full zero install (which was after the fault occured) but the problem persisted.
    Is the memory the cause of this issue or is it time to get a new keyboard? I tried to run the apple hardware cd that came with the machine but it refuses to show up on the desktop and I cannot boot from it.
    Any help would be very VERY much appreciated.
    Also...is there any way of contacting apple with this? The contact us section pretty much just points back to the support site which doesnt have a solution.

    nope that doesnt seem to be it. The caps lock light comes on at startup..so it seems it has the capability to work.
    the keys which dont work seem to be:
    caps
    tab
    escape
    the squiggly thing next to left shift
    and the key next to one
    thanks for the suggestion though

  • I am trying to figure out why my Apple ID is not working properly.

    So at first i was trying to install some new apps from the app store on my iphone 4. And a message box kept popping up saying i needed to "agree to itunes terms of use" and so i would click on it so that i could agree and there was a little box that said "send to email" so i tried clicking on it and nothing would pop up, it was as if it wasnt even a button. So i tried scrolling all the way to page 52 and there was no button that said "agree" or anything like that. So just now i created a new apple ID and i deleted my old icould account and then i signed in the apple store with my new apple ID and password. So then i proceeded to install an app from the itunes store so i typed in my new ID and password and then a little message box popped up saying "This Apple ID has not yet been used in the Itunes store" so i click "review" and it says to choose my country and click next so i click United States and i scroll down but theres no "next" button. like its just blank.
    can someone please help me...

    Go To:  Settings > General > Usage
    This page lists all of the apps that are on your phone,and shows you how much space each is using.  It shows 10 apps, and at the bottom of the list is an option to "Show all Apps."  In addition, they are listed in order of the amount of storage space they are using.
    If you select each individual app by clicking on the ">" beside it, the next page shows the info for just that app, including the name, version, App size, and amount of storage space used by Documents and Data associated with it.  You also have the option there to Delete the App.

  • Why does my location services not work properly?

    Over a week ago, my location services stopped working. I can't view local weather on the default weather app, the default map can't find my location, and none of the other apps I have that look for location can view my location. I tried turning location services off and back on but it won't fix the problem. How can I fix this while waiting for the computer to be repaired?

    Haven't checked at home, but if this is the problem, then how come it still won't work at places like Starbucks or other wifi hotspots? I'm at Starbucks right now, logged on and checked my email so I saw your reply, remembered that the router disconnected me at home last week and then I was able to get back on. So, I thought maybe that's the problem - what you said - so I tested my location on the map and it STILL won't work! I'm so irritated about it, since I rely on that app to help me determine the distance and time to walk to locations from my current location.
    I was able to "solve" the weather app by just adding my city instead of using the local weather. I'm hoping I can try restoring my iPod later this week if the laptop gets fixed by then. I HATE restoring, though. I could do it using iCloud but most of my music is off CD's and I haven't paid the $25 to upload all of that so I'd temporarily lose those songs.

  • Why is the intelligent keyboard not working properly

    I cannot use formulae or perform other functions in numbers on my ipad. The correct keyboard is not opening up when double tapping any cell?

    Not quite sure what you mean by "correct Keyboard". Do you mean the correct functional selection for the cell (Number, Date/Time, Text, formula), or somethign else? I beleive the default is nor number, but it should shift to a different one depending on the current format of a cell.

  • Downloading iTunes 7.6 for windows not working properly

    OK, I downloaded iTunes 7.6 for windows 3 separate times. The first time after completing the download, an error message popped up that states: "iTunes cannot run because some of its required files are missing. Please reinstall iTunes." Well I went back to your site two more times to download the software again, each time I get a pop-up that asks if I want to remove iTunes or repair it, each time I select REPAIR and it goes through the download process and says it is complete. Then each time I attach my shuffle, that error message pops up again and says there that iTunes is missing files. SOMEBODY PLEASE HELP!!!! I CANNOT ATTACH MY SHUFFLE TO ACCESS MY MUSIC!!!!

  • Why is my keyboard is not working properly?

    I just purchased a new MacBook Pro. When I want a question mark, my 'shift' 6 gives me a ^.  When I want a e with s circumflex, it gives me a /. 
    I am properly set on English as my language.Where do I go from here^

    Try a reset first: Press and hold both Sleep/Wake and Home buttons until the Apple logo appears.
    If the reset doesn't fix it, try a restore:

  • Why is tail unix command not working properly on a mounted drive?

    I mounted a remote drive on my mac, smb://some-windows-host/some-folder.
    I thought I'd be able to do a 'tail -f' on a file on this mounted drive, but it seems the changes aren't coming through.  What's wrong?
    Do I have to enable someting?
    Thank you so much.
    JS.

    Kind of late, but for anyone that sees this in the future.
    It's possible that the process that is modifying your file is creating a new file with the same filename.  The 'tail -f' command reads the file based on it's 'file descriptor'.  When the file gets rewritten by the other process, then the file descriptor changes.
    So to track a file by it's name instead of it's descriptor, you should use a capital 'F', like 'tail -F'.
