FXML 8 Binding Expression does not

While I do the Java for 15 years and more, I am new to JavaFX and FXML, so please don't mind if I ask something obviously stupid...

I put in place a liaison between my opinion FXML and the Java controller in the controller's initialize() method.

It works really well: this.countButton.disableProperty () .bind (this.model.countingProperty);

Now, I have discovered the FXML 8 documentation on the Expression bind (http://docs.oracle.com/javase/8/javafx/api/javafx/fxml/doc-files/introduction_to_fxml.html#expression_binding) and tried to do the same here: < button text = "Count" fx:id = "countButton" disable="${controller.model.counting}"/ > but that simply does Nothing. It throws an exception, or there is no link!

What is my fault?

If you want to make available to FXML this 'model', you need to set in FXML (AFAIK).

I don't have the time to test it now, but I think you can do

Model model = new Model(...);
FXMLLoader loader = new FXMLLoader(someURL);
loader.getNamespace().put("model", model);
Parent root = loader.load();

and then the FXML will 'see' the model. But it feels like a bit of a hack.

  • My Port of Air express does not appear on the usefulness of air port on my iPhone

    I have an Apple air port express router to connect the remote speakers. I installed a new router wireless modem Arris and reconnected successfully the apple tv. However, the air port express does not appear on either of my iPhone airport utility or the menu wi fi iPad. So I have no way to connect air port exress my router to base.

    If your AirPort Express Terminal has already been configured as a receiver AirPlay, and it is not on the current WiFi, AirPort Utility has no way to find. I suggest that you use the button on the airport to restore it to factory settings and to reconfigure it according to the manual. You can also configure your new router to use the same SSID and key as the prior network. Then, the airport will not know the difference.

    If Bruce's response does not help, then move all the dbx files in the message a directory of storage for OE will create a new message store.  Then see if that solves the problem.  If this is the case you can use the file | Import | Messages to get from the directory to which you move them.

    Hello

    1. which antivirus program is installed on the computer?

    2. have you upgraded from Windows XP to Windows Vista?

    Outlook Express comes with the Windows XP operating system. It's an e-mail with Windows XP client.

    With Windows Vista email client is Windows Mail.

       

    The ccsvchsy.exe list file you most often is a process associated with Norton 360. However, malware is sometimes assumed the names of the legitimate files in order to deceive the end user.

    I suggest you make a system full scan just to be sure.

    Here is a link that will give you information on how to perform a full scan of the system:

    http://www.Microsoft.com/security/scanner/en-us/default.aspx

    , Note 1: The Microsoft Safety Scanner ends 10 days after being downloaded. To restart a scan with the latest definitions of anti-malware, download and run the Microsoft Safety Scanner again.

    Note 2: The data files that are infected must be cleaned only by removing the file completely, which means that there is a risk of data loss.

  • Airport Express does not work

    I need help. I have an Apple Airport Extreme and extend it with an Apple Airport Express. One day I needed to my extreme, which I did, forward port (which was for the xbox, and I followed this: Xbox NAT open (Apple routers)) I then updated my Airport Extreme. Subsequently, my Express glows green but it does not actually give a signal, I stay connected to the extreme, so I tried to use ethernet with the Express, and who won't let me connect to the Internet. So, I need help.

    If the Express was created to connect to the AirPort Extreme using a Wi - Fi connection, and you later connected to an Ethernet cable to the Express... that creates a huge feedback loop that actually blocks the network provided by the Express.

    You will need to restart and reset the Express back to default settings, then set up again.

    If you want the Express to connect permanently at any time to the extreme by using an Ethernet cable, then you must establish this connection before you implement the Express again. The Ethernet cable can never be disconnected.

    If you want to Express to extend the wireless network, then you use an Ethernet cable to the installation.

    If you need more tips, post back to let us know what operating system your Mac is running or you use a PC or an iPhone / iPad to configure things.

  • my airport express does not extend to my network

    Hello to you all guru out there...

    I 5g internet and comes with the router and signal is fantastic in the main lounge, but it is a large apartment and once I get my room the signal decreases considerably.

    I bought an Airport Express and it connects to the wifi perfectly, green light and everything, but it does not extend my wifi network...

    Do I need to have another Aiport Express hooked up to the main router, then extend the Airport Express wifi or should I get an Airport Extreme?

    Any advice or help is greatly appreciated.

    Thank you!

    Do I need to have another Aiport Express hooked up to the main router, then extend the Airport Express wifi

    Yes, the "main" AirPort Express should be connected to your router using a wired Ethernet cable connection, permanently. This Express will be set to "create a wireless network.

    Other Express your distance can then be configured to "extend a wireless network.  In its current form, your existing Express is configured to "join a wireless network.  It will work for AirPlay like that, or allow you to connect a supported USB printer, but it cannot extend a network provided by a third-party router wireless.

    Regarding matching them things, it would make sense to use two airport expresses, or the two extremes of the airport.  The extreme might be your "primary" router if you wanted to, but the Express would not be able to expand the capacity of faster speed to the extreme.

  • Airport Express does not connect to WiFi!

    My Airport Express has lost its connection to the WiFi and cannot reconnect, keeps flashing yellow!

    It is only used to stream music from my iPad and not connected via ethernet. Its working well for 2 years until he lost the connection to my iPad because I took the iPad out of range of WiFi. Now, I can't get the the airport to connect to the WiFi again.

    I tried to reset button Reset 20 sec, also tried turning setting turned off and now the reset button for a maneuver on once again, however, does not. Any ideas?

    There may be a firmware update available.

  • Forced to model in the file dialogue VI Express does not

    Hi all

    I have a simple VI to open and read a file.  I use 'File dialogue Express VI' to get the file name of the user, in order to use the "pattern" of entry to limit the type of file.  Unfortunately, appears not to limit the list of the files somehow.  I enclose a picture of my code, and the dialog box produced during its execution, which demonstrates that the VI does not indeed limit the list of files.  Is this a bug?  No one knows how to fix?  I'm under LV 2010 10.0 32 bit on a 2.93 GHz Intel Core i7 iMac with Mac OS X 10.6.4.
