My Two-year Pain with JDeveloper

The problem I am about to describe has been around since JDeveloper 10g, and the problem is explained by Didier at “http://blogs.oracle.com/Didier/2006/11/22#a162”. The Visual Editor does not display the Trinidad and MyFaces or JSF components in the preview but rather in rectangle or outline view.
Imagine spending a week over this very issue. I have read Didier, and Frank Nimphius (much older) solutions but nothing came out of it. It seems that even JDeveloper insiders don't know what the problem/solution is. As I alluded earlier, this problem is over two years old [since 10g]. I should know because, over the years I have abandoned JDeveloper thrice because of this problem. But I return due to amnesia and belief that SURELY, the JDeveloper team must have rectified the problem.
I would like to ask JDevelper insiders as to why even after two years the problem still persist. And further, why no one has a STRAIGH-FORWARD ANSWER to the problem. If one can't figure out what is causing the problem, how could one solve the problem.
I thought the problem originated in “web.xml.” but these few days, I am not sure anymore: I have two web projects, the WYSIWYG works fine in one but not the other. I tried using the good project's “web.xml” and “faces-config” in the bad project but to no avail. As I said, this problem is TWO YEARS or so old; does anyone know EXACTLY the cause(s) of the problem?
Tool Set
Trinidad 1.2.6 (I am not using ADF Faces)
JDeveloper 11g Preview 3
MyFaces 1.2.2
OS: Linux
Thanks in advance

Hi,
note that Trinidad 1.2.6 requires JSF 1.2, which is added to JDeveloper 11 (as you use it). The default bundling of Trinidad is 1.2.4 and will be updated to a newer version with the next technology preview. I don't expect this Trinidad version to work in 10.1.3.
I didn't try to configure Trinidad 1.2.6 in JDeveloper 11 TP3, but since the changes are only on the component level, you should be able to do this by swapping out the Trinidad libraries in JDeveloper 11
Frank
Ps.: I don't have a Linux box available to verify a possible platform issue. However, if you can't get it working, maybe you have the chance to verify this on a Windows box.

  • UPGRADE PARTY! ***TWO YEAR CONTRACTS ONLY***

    Now we all know we are SUPER PSYCHED for this new iPhone 4. FINALLY, VERIZON. YOU SHOULDA HOPPED ON THAT BOAT WHEN IT WAS IN DOCK FOR YOU.(You know we had the opportunity to have the iPhone first, right?) Anywayssss, the ones that are happy are the ones that have upgrades. For those that have invested in Androids and phones that have released since last May, but would rather have an iPhone, you're in bad shape (like me). We have signed a two year contract, with no way of getting out of paying a full ridiculous price for another phone. Should Verizon give free upgrades? Anyone else agree? What do you think?
    Note: I'm not a fan of haters. 

    Well what aggravates me is that they are being wishy washy on allowing annual upgrades...which is a legitimate upgrade that is currently on our account.  Other rumors are that the annual upgrade will magically disappear on the 16th.
    So why all of a sudden can we not use an upgrade that we rightfully earned (if this is the case).  And if its not the case and we can use it, then please have your website reflect this when we check eligibility for the iPhone...especially when it shows us eligible for any other phone on the site at a discounted upgrade price.
    Treat your loyal customers well....give us what we've rightfully earned.

  • Signed up for two years two months ago and now they are taking away my Music Channels!!

    I signed up for the triple play back in December for two years, HD ultimate. I received an E-mail yesterday that all of my Music channels 1800 to 1845 will be gone unless I pay another $35 a month!!
    I called up and Verizon says our provider is changing their plan. I indicated I signed a two year contract with Verison and I can care less about their provider isssues.
    So what are my options? Anybody else dealing with this **bleep**?
    Thanks

    I wouldn't assume because you or others may not have receive notice as an indication that this isn't possible. For example, I have yet to receive any notice from Verizon about the removal of the Bridge TV & Funimation channels like many other customers. Verizon is dropping the ball with exisiting customers and their own customer service reps based on conversations I had with them. I'm not sure if it is conscious tatic or effort of not informing exisiting customers of programming changes. But it seems to be an ongoing issue by just the posts you see on this forum.

  • I ordered my Macbook Air with Aperture two years ago. I now have an iMac - can I use that with Aperture in any way?

    I ordered my Macbook Air with Aperture two years ago. I now have an iMac - can I use that with Aperture in any way? I appreciate that it is a different computer but I am now the end user of both devices and I was just wondering if it was possible.
    Thanks,
    Sean

    The answer would be in your software license agreement for Aperture. However if you cannot locate it you can ask in the Aperture forum, the link for that is:
    https://discussions.apple.com/community/professional_applications/aperture
    However I believe you can have Aperture installed on two machines however only one may be using it at a time.
    On the new iMac launch the Mac App Store - Purchased - look for Aperture and download to your new machine.

  • Hi, i've just got a problem with my macbook pro: I bought it two years ago and suddenly, it stopped working. Im freaking out. No answer from the people hwo suposed to know about these problems. Any tip??

    Help!
    i had a problem with my macbook pro: on tuesday 16th (agoust, 2011) I went to a friend's house and show her some document i had in my computer, then i turned off my mac and it asked me: "there are some actualizations available, do you want to update before turn off?" i clicked on yes, waited for update and then the macbook turned off. When I got back home, I tried to turn it on again.... but nothing: it didn't sound baaaammmmm as allways, it didn't reacted. I tried again, but useless.
    The next day i went to one of these "authorized management centers", but they coudn't say anything or do anything about it. First they told me the problem was the battery, then the hard disk, then the video card... but don't. I left my mac there by two weeks, hoping they could help me, but they didn't. So I picked it up and go to other place.
    The rare thing is that i have just two years with my mac, and i didn't do anything stupid on it (didn't fall, get wet, microwave, hot, shocked, hit or anything) It just stopped working. Two times it turned on. But if not, it's the same story:
    When i pushed the button to turn on, sounds like baaaaaammmm, but then again, and again, and again, and the screen doesn't get blue or anything, it appears a foder with a "?" and then the computer turns off...
    Im wondering if this is a problem on this computers, because some of my friends told me things much like that that happened with their macbooks.
    What's going on??? why this is happening?? cn you help me?

    This article may help: A flashing question mark appears when you start your Mac.

  • HT204053 Can you merge two Apple IDs into one?  It was a common issue caused by the iPhone 4 and has been corrected, but transferring purchases in iTunes is a pain with two IDs.

    For a brief time when iPhone 4, iOS 4 came out, many of us ended up with two Apple IDs.  I want to know if anyone can please provide me with simple step-by-step instructions on merging two Apple IDs into one?  It would make transferring purchases on iTunes much easier and reliable.  I realize i desperately need an iOS update, but i had no laptop for over two years!  I'm posting a cry for help on that in another community.  Thank you all.

    No,
    Apple IDs cannot be merged. You should use your preferred Apple ID from now on, but you can still access your purchased items such as music, movies, or software using your other Apple IDs.

  • Two years later, a random, hopeless e9105z PC from Hewlett Packard with continual freezes.

    I posted a message over a year ago with no luck, and wanted to see if a second posting would give any advice.
    In short, my PC freezes randomly, with no predictability or triggering events.  The only thing that happens is the system locks up, the mouse pointer is frozen on the screen, and the system is essential unuseable.  All I can do is a hard power down.
    Over the 100+ freezes I've had, here are some odd things that have happened:
    (1) Around 30% of the time, pressing F8 to run system diagnostics fixes the problem.  When I run system diagnostics, 90% of the time, the system comes back perfectly clean.
    (2) Of the times that systems diagnostics has been run, here are the errors that have been found:
    --several times, it warned me that my Western Digital 640GB HDD was about to fail
    --two times, it warned me that I had no boot path
    --two times, it warned me that my Intel X-25M SSD was on the fritz
    (3) Sometimes I can turn back on and be okay, other times, I have gotten something to the extent of 'boot sector missing, press Ctrl-Alt-Del to reset'
    (4) system has been unplugged/replugged several times, motherboard dusted off, SATA connectors unplugged/replugged, etc.
    (5) the system sometimes will fully boot up in Safe Mode, other times it just freezes up during the initialization.  when it does hang in Safe Mode, it does not get hung up on the same file twice.  
    (6) For Windows Update, the NVIDIA nForce Serial ATA Controller June 2009 driver update crashes my system.  I have to do a system restore.  This update is hidden/disabled in the Windows Update profile
    Recently the freezes are happening once every 1-3 minutes every time I turn on.  They used to go once every 2 months, then maybe once every 2 weeks.  Tonight, oddly enough, my computer has worked for over an hour without problem.
    HP's tech support has been useless.  It seems like they are more or less following a flow chart that has little applicability to this situation.  Telling me that my printer and Microsoft keyboard were the problems.  (Really?  Am I that stupid?)  They succeeded in gringing me down over the phone.  And besides, I'm out of warranty.  
    Is this most likely a bad motherboard, or an NVIDIA chipset bug, or a Windows 7 compatibility issue?  I have no idea where to start (or end) in this problem.
    My configuration:
    Win7 clean install
    6GB memory (Stock)
    Phenom II X4 945 (stock)
    Intel X-25M primary/boot 
    Western Digital 640GB HDD (stock)
    Microsoft mouse
    Microsoft keyboard
    A printer that is hooked up about 30% of the time (Lexmark X8350 POS)
    Any help is appreciated.  
    Thanks,

    I am having a similar issue with random freezes/hangs as many posts with my Pavilion Elite m9350f that I bought a year ago or so.  I have automatic update turned on and have gone to HP and MSFT sites to ensure all drivers/software are current.  I have also attempted to clear the fan and heat sinks of lint.
    This has been a chronic issue since the PC was new that has good days and bad.  On good days I will not see a crash at all.  Bad days, the PC will randomly hang every 5 minutes or so EVEN when cold, while in BIOS setup, and operating in safe mode.  The software applications I use don’t seem to be relevant (they are limited to Office Pro 2010 and StarCraft II).  The typical “crash” is a hang that freezes the display and all user I/O.  USB ports will often power down (laser mouse light will often turn off as does PS2 keyboard).  I also don’t hear the buzz of the hard drive (it appears to spin down).  I do hear the fans even after a hang.  A power cycle is needed to reboot and bring the PC back online.
    The ‘crashes” seem to corrupt data on the HD.  As a workaround to fixing this issue, I reinstalled/repaired Vista several times because as time from install increased, it seemed bad days became more prevalent.  Then, three months ago, because the PC crashed too hard to reload/repair vista, I installed Windows 7 and replaced the hard drive.  When I attempted to attach the faulty hard drive as a secondary drive, my PC would not boot (faulty drive was confirmed?). 
    Now with the new OS and HD, I am seeing the same problem again.  Like you I am running out of ideas.  I took the PC in for troubleshooting with the GeekSquad where they kept it for a week (three days longer than planned) to run several virus scans and hardware diagnosis programs.  All test passed.  The tech claimed to not duplicate a crash so I thought maybe it was my keyboard and mouse.  I bought new keyboard and mouse on the way out of the shop.  When I got home, the hangs continued…another bad day.  The event log recorded several crashes while the PC was in the shop…I hate being told lies.
    My PC Event viewer logs close to 50,000 events most of which mean absolutely nothing to me.  I am unable to find events that appear prior to the 41 and 6008 recovery error notices that might signal a cause.  However, I am getting many instances of Event ID 12 with indicates “The platform firmware has corrupted memory across the previous system power transition.  Please check for updated firmware for your system.”  I assume this means to look for an update to motherboard BIOS?  I am working on finding the right BIOS now.  I don’t believe it likely a BIOS update will fix the hang issue.
    Reading through the forums, I see this issue on many different PC models configured with many variants of software.  Like you I don’t have my PC working correctly yet.  Maybe we just need to accept that we bought a lemon and start replacing parts?  I’m thinking power supply and motherboard…

  • My Iphone 5 will no longer work with my two year old Bose dock?  I'm using an "Apple" 30 pin to Fire adapter

    My Iphone 5 will no longer work wiht my Bose Dock?  The dock is two years old and I'm using an "Apple" 30 pin to Fire adapter?  It stopped after software upgrades?

    I Have the exact same issue. Bose sound dock 3 and it does not work for me with my iPad air 2 and iPhone 5 anymore.
    Used to to work fine 2 weeks ago.
    Is it to do with updating to iOS 8.1.3?

  • So for the past two years I've shared an iTunes with my sisters. This year i want to take my iPhone off, but keep my music. How do I do this?

    So, for the past two years I've shared an account with my sisters. This year I got my own laptop and I want to take my device off that iTunes, but still keep the music I bought. How do I do this?

    You should be regularly importing your photos on your device to your computer. That is where all of your photos should be permanently stored. What is on your device is selected when you do a sync to iTunes. Once you select your device, you click on the Photos tab, and select which photos, albums or events you want specifically downloaded to your phone. If they have all been backed up to your computer, then you will be able to select whichever ones you want on your new device.
    Contacts would be backed up as a part of the backup process to iTunes. Here is a support article with specific information about what is backed up:

  • I am currently on a plan with my parents, but my two years is up and I am due for an upgrade. My plan was to drop from my parents plan and join my fiancee's. Will I be able to get a discounted phone, and keep my existing number?

    I am currently on a plan with my parents, but my two years is up and I am due for an upgrade. My plan was to drop from my parents plan and join my fiancee's. Will I be able to get a discounted phone, and keep my existing number?

    You'll need to do an Assumption of Liability. The parent that is the account owner and your boyfriend will both have to be at the store to do this. Your line is actually your parents and it will be your fiancee's once the change is made. But you should be able to get your upgrade and you definitely get to keep your number. Also depending on your fiancee's credit history there may be a security deposit required.

  • I have my ipad notes linked to gmail and suddenly disappeared when I put the sim card into a new iphone, the funny thing is that almost all disappeared except 4 and with different dates up to two years. Why did this happen? No way to recover them?

    Wow, Karan Taneja, you've just embarrassed yourself on a worldwide support forum.  Not only is your post ridiculous and completely inappropriate for a technical support forum, but it also shows your ignorance as to whom you think the audience is.  Apple is not here.  It's users, like you. 
    If you would have spent half the time actually reading the Terms of Use of this forum that YOU agreed to by signing up to post, as you did composing that usesless, inappropriate post, you (and the rest of us on this forum) would have been much better off.

  • My ipod works fine, but won't connect to my car anymore.  It did for two years, I have had the car checked out, and the car works with others' ipods and iphones.

    My Audi is set up to be iPod compatible.  For the first two years of the cars' life, my ipod worked fine.  When it went out, I had the dealer replace the connection wire and check the system.  My car now works fine with iphones and others' ipods, but not mine.  I tried rebooting it and powering down, but nothing has worked to get the car to recognize the ipod.  Would really appreciate anyone's thoughts on the matter.  Many thanks.

    So you tried everything here:
    iOS: Device not recognized in iTunes for Windows
    If you  have iTunes 11 turn on the Sidebar. Go to iTunes>View and click on Show Sidebar. You can also do a Crtl+S to show the sidebar. The sidebar is where Devices appears. and Control+B to show the Menu bar
    Try connecting to another computer to help determine if you have an iPod or computer problem.
