Design tab shows nothing

All of a sudden the design tab is not showing any of my UI components. The application compiles and runs showing all components though. Something I've changed in the code obviously has confused JDeveloper (3.0) but what? How do you debug these types of problems?
bob

Did you create the components using the Design tab and component palette, or did you code them by hand?
If you coded them by hand, then you need to make sure of the following:
1. Your constructors use the following syntax:
JButton b1 = new JButton();
vs.
JButton b1;
2. You have a jbInit() method in your frame class (or applet) that includes the adds for your components.
If you created the code yourself versus letting JDev do it, then JDev needs specifically formatting things in order to 'reverse-engineer' the code back into a GUI mode.

  • Screen only shows 3 tabs and nothing under each.

    I turn on ATV2. I only get the 'internet', 'computers' and 'settings' tabs. Nothing under 'internet'. Can't share comp. And everything under 'settings' is still there. I checked for updates. It tells me it's up to date. I wanna watch netflix or youtube. What can I do? Please help.

    This issue can be caused by the Babylon Toolbar 1.1.8 extension

  • JDeveloper Design tab stopped working

    Hello,
    Once upon a time
    Without an obvious reason
    My JDeveloper 11R2 design tab stopped working. It's just showing me page blocks instead: http://img827.imageshack.us/img827/5954/designbroken.png
    Preview tab is also broken: http://img688.imageshack.us/img688/7563/designbroken2.png
    It is just a JSF facelets page, nothing unusual. And it is not only this page, but all of them, so it is IDE trouble, not my code.
    Tried to restart. Tried to reboot. Nothing.
    On runtime everything's fine.
    I really wouldn't like to reinstall JDeveloper and resotre all the IDE and IntegratedWebLogic configutration back again.
    Is there any hope for solvation?
    Thanks.

  • Netbeans visual web app design tab won't load?

    Is there anybody that has the following problem when trying to start a new visual web application in Netbeans 6? If so, could you help me fix the problem?
    Every time I try a new visual web application in Netbeans, the design tab won't load and I get an error message. I can use the Java tab and the JSP tab with no problems. It's just that the design tab says "please wait loading" but it nothing ever shows up. I can basically do everything else, except for dragging things from the palette to the design tab. The error message is:

  • Can't edit in Design tab - "overflow: hidden (double-click to edit)" - cause, remedy?

    In the Design tab, the content of some web pages becomes uneditable (where it had previously been editable), even though it is in an editable region in the template. All of the uneditable text has a black background. When the cursor is floated over this text a popup gives the message "overflow: hidden (double-click to edit)". (Note: the text is still editable in the Code tab.) Double clicking in the Design tab often doesn't do anything but sometimes corrects the problem. The following also didn't help:
    1. Making revisions in the Code tab and then refreshing. (The revisions show up in the Design tab but the text there is still uneditable.)
    2. Closing and reloading the page.
    The content of other pages that use the same template remains editable.
    What causes this problem?
    What is the best method to prevent it and correct it?
    DW CS6
    Win7 x64
    Thanks,
    Don C.

    The problem is always a side-effect of the use of the overflow:hidden style. So why use it? It's tremendously valuable as a way of clearing floats inside a container, rather than adding a float clearing page element. And besides, if you can still edit the content in Code view, why worry? Anyhow, paste this into a new HTML page and try it.
    <div style="height:100px;overflow:hidden;">
    <p>This content will not be editable without double clicking on it. Furthermore, any floats contained within this div will be cleared before closing the div, allowing the div to completely wrap its contents.</p>

    </div>
    In Design view, you will only see two paragraphs. When you click in either of those two paragraphs, you will not be able to edit anything. When you double click you will see the div expand to show all 4 paragraphs, and you will then be able to click and edit at will.

  • Adobe muse - can't see my Edge animation in design tab!?

    I have a problem, when i have made mit edge animation, and placed it in muse, i can't see it in the design tab, but when i click the preview tab i shows, and i can also see the animation in browser!? Anyone who can help? :/

    Hi,
    Yes I've had the disappearing animation problem. It shows in preview but not in design,
    I deleted and re-inserted it. That cured it - but for how long.
    This latest update has been a disaster for me.

  • Got an alert from Mozilla FireFox saying I have virus on CPU, however, Avira software showes nothing. What to do?

    While browsing a Mozilla Firefox alert popped up, stating that I had some activity going on. It said push the start tab to run a test, I did this. The results were that I had a virus (Trojan horse and Malware) on my computer. To fix, it said to download something from Creative Technologies...I did not download - not knowing what it was. My Avira anits-virus software shows nothing. Who is right/trust, and what should I do if I encounter it again???
    thank you for your help
    gerry

    If you suspect malware issue, Do a malware check with some malware scan programs. You need to scan with all programs because each program detects different malware. Make sure that you update each program to get the latest version of the database before doing a scan.

  • My mac mini is running slow.  Bought it in 2009.  Activity monitor shows nothing running that should not be.  Someone suggested it might be my operating system?  Check for software updates, and I am current.  Suggestions?

    My mac mini is running slow.  Bought it in 2009.  Activity monitor shows nothing running that should not be.  Someone suggested it might be my operating system?  Check for software updates, and I am current.  Suggestions?

    Open Activity Monitor, Show:>All Processes, sort on CPU%, see if anything using too much CPU% when this happens, click on Memory tab, do you have many Pageouts?
    Open Console in Utilities & see if there are any clues or repeating messages when this happens.
    Check the S.M.A.R.T. status of the drive in Disk Utilty by highlighting the Drive & looking at the bottom of the window.

  • Trying to open a new tab and nothing happens

    All of a sudden, when I click to try and open a new tab, absolutely nothing happens,

  • Firefox just updated to 5.0.1 when it opens it opens two tabs, one a restore session tab and the other Firefox home tab. Nothing appears in the restore tab and everything freezes. Only way to get out is to ctrl, alt, del.

    After updating to Firefox 5.0.1 and trying to open Firefox, it opens two tabs. One is the restore session tab and the other is the Firefox home tab. Nothing opens in the session restore tab and once the Firefox home tab loads the browser screen freezes with no crash ID's listed. The only way to get out is thru the task manager and ending the process. Firefox worked fine before updating.

    Hi glivezey,
    Try typing ''about:home'' into the address bar. Is that the page you are looking for? If so, go to ''Tools > Options > General'' and save it as your homepage. If that home page doesn't show up the next time you start Firefox, you should look at [[Preferences are not saved]].
    Hopefully this helps!

  • Design tab issue with Premade template

    I just purchased a premade template and am trying to customize it for me in  Dreamweaver. I am unable to click on the design tab it will only display the code tab when I open the .xml file. Is there some sort of prefrence I have wrong or can I not access the design tab function on premade templates. Also I am only using the trial version for now.
    Thank You

    Design View in DW shows only files which contain HTML markup e.g. HTML, PHP etc.
    An XML file is text only (usually data to populate something in a HTML page or settings for a feature in a HTML page) - so there's no HTML page to show.
    Open a HTML or PHP page in Design View.

  • Firefox won't open .ppt downloads. Instead it merely opens a new tab with nothing in it. How do I fix this?

    I used to be able to open .ppt files on webpages with Firefox. But now they don't open. Instead, Firefox opens a new tab with nothing in it. I have already checked the settings for which programs are to be associated with which files, but it is still not working.

    Uninstall the Ask toolbar and it should work again. There is a compatibility issue with the Ask toolbar and Firefox that prevents new tabs from being opened.
    There are a couple of places to check for the Ask toolbar:
    * Check the Windows Control panel for the Ask Toolbar - http://about.ask.com/apn/toolbar/docs/default/faq/en/ff/index.html#na4
    * Also check your list of extensions, you may be able to uninstall it from there - https://support.mozilla.com/kb/Uninstalling+add-ons

  • Visual Studio Tabs - Show Title instead of Work Item Number?

    When opening individual work items in Visual Studio, the tab in the document well just says "Task 100485" or "Bug 38374".  Is there a way to instead have it show the Title of the work item?  Just showing the number isn't really
    helpful when quite a few are kept open.

    Hi Brian,  
    Thanks for your post.
    We show view the work item Title in each opened work item form in VS. As the work item’s tab has fixed width in VS, so if show the work item Title in each work item’s tab in VS, it will costs the wide width, if work item’s title is long, maybe two or three
    work item tabs can show in VS at the same time.
    As far as I know there’s no default way to change work item’s tab show work item Title in VS. For this scenario, please
    submit it to User Voice site at: http://visualstudio.uservoice.com/forums/121579-visual-studio. Microsoft engineers will evaluate them seriously.

  • HT201272 i can't see my purchased apps in itunes on new ipad when I go into the itunes store. It shows nothing. I haven't changed my ID or country of purchase. It shows that I would have to rebuy them when I go into the store.

    i can't see my purchased apps in itunes on new ipad mini. when I go into the itunes store. It shows nothing. I haven't changed my ID or country of purchase. It shows that I would have to rebuy them when I go into the store. Is there something in settings on Itunes I need to change? I do not have cloud.

    Yes I am looking in the app store. When I look in Itunes on my computer and look at purchased apps it is there. And when I go on my other device and look at apps purchased all apps are there.
    The new ipad doesn't show any apps purchased when I click on apps purchased and when I search the app store it doesn't show it is purchased. I am wondering if I am just missing something...need to turn something on in options or something. Never had this problem with previous ipad when I set it up.
