Node in the fxml file not visible

• My event.result may or may not return a node in the xml file. How can I avoid that TypeError: Error #1009:

  My event.result may or may not return a node in the xml file. How can I avoid that TypeError: Error #1009: cannot access a property or method of a null object reference.

  I have a very simple question. I want to take the value of

  Event.Result.Item.nodeindex1.nodeindex2.Row.MyValue;

  and assign it to a text field

  mytextTi.text = event.result.item.nodeindex1.nodeindex2.row.myvalue;

  But if a part of the tree is missing, which is also valid, so I get TypeError: Error #1009: cannot access a property or method of a null object reference.

  I tried various solutions such as the following. Is there any simple way to do this?

  If (event.result.item.nodeindex1.nodeindex2.row.myvalue! = undefined)-does not work

  Unfortunately, one must test all levels to ensure that it is not null before the reference to it. You can take advantage of the short-circuit evaluation in tying together, for example

  if (event.result.item
      && event.result.item.nodeindex1
      && event.result.item.nodeindex1.nodeindex2
      && event.result.item.nodeindex1.nodeindex2.row
      && event.result.item.nodeindex1.nodeindex2.row.myvalue)
  {
      // access the variable
  }
  else
  {
      // one of the XML nodes in the path is null
  }
  

  Or you could stay away from her a little hacky and wrap the reference in a try/catch block.

• How to include a license header in the fxml file?

  How to include a license header in the fxml file?

  I tried the xml block comments <! - mylicense here - >

  but it has not been accepted by the manufacturer of the screen.

  Also, I asked, even if it had been accepted, would have saved the return - or deleted header screen generator?

  All XML documents must begin with an XML declaration.

  If you have your file fxml starting with the following lines:

  Hello

  XYChart should be passed their axis in the constructor.
  Developer SceneBuilder preview comes with a set of elements dropable XYChart where the nature of the X axis and the Y axis is preconfigured.
  In other words, when you drop an AreaChart in SceneBuilder, the area chart is preconfigured with a NumberAxis Y and a CategoryAxis X.
  From what I see, it seems that your series requires a X NumberAxis and Y NumberAxis.

  A way to make your example work replace manually

  
  
  
  
  
  
  

  with

  
  
  

  in the FXML file. SceneBuilder should be able to happily work with such a file, it's just that at the moment the library in SceneBuilder has all XYChart configured in this way.

  Hope this helps,

• I try to install vista on my laptop but a letter of the key is not visible, all the other parts are very well including the serial code, is there another way to get the key of the other information?

  Taché product key

  Hello

  I try to install vista on my laptop but a letter of the key is not visible, all the other parts are very well including the serial code, is there another way to get the key of the other information? The laptop currently has non-OS I've tried to reinstall.

  Thank you

  Product keys are bit-agnostic - they don't care if it's 32-bit or 64-bit.

  However, cannot legally use the recovery disk from one computer to a different constructor machine - as other licenses are not properly paid..

  There is nothing nonetheless to try all possible variations on the absence of character (there are only 25, after all the )

  Other than that, your best option is to contact the manufacturer and order a set of recovery disc for the machine. I do no download available for Vista with SP2 - but you can download Vista with SP1 and create the disc.

• Hello! I get the message "File not found" when I try to access my photos

  Hello! I get the message "File not found" when I try to access my photos in lightroom, and I can't find my photos! I had cleaned up my Mac and deleted by mistake in a different location and now only a gray peak appears in LR, along cable message, file not found. I had saved the raw disk backup files, but it won't let me import into lightroom. (Alright will appear in the import box, but it won't let me even click on it to add. Help!

  In the grid, right-click on an image of 'missing', select 'go to the folder in the library.

  If the folder view does not resemble what you show Finder, right-click on a folder and select 'Show the parent' '; repeat if necessary.

  This will show you where LR thinks that the file was originally.

  You can try to put the images where they were, or place them go elsewhere and 'move' the file in LR.

  Fluidity in the mode of the image is not visible in the magnification of 100% and above.
  It is perfect between 25% and 66%. If I disable hardware acceleration, it works but slow. Does not work with the PSD, jpeg, 8 or 16-bit. I have reset the PS.

  A Mac video card with 512 MB of vram is marginal. A 256 MB card enable GPU mode to liquefy to work at all, even on the small images. The smaller image work about only works in CPU mode, make a smaller selection just the part of the image you want to distort and then start fluidity in CPU mode using the down option. It will be slow but should work. Get a stronger video card (more vram) would be the best solution.

• Models of DW: 'this document uses the following files not in this site.

  I recently started using DW templates in CS6. It was a bit frustrating at first, but seems well wouth it. I've created quite a few pages in the folder root of hares and have no problems there. However, I created a new folder to a different section of my site (mysite.com/new_folder/new_page.htm), and then went to save a new page of the model and got the message "this document uses the following files not in this site. Its the same site, just a new folder which is placed at the root.  When I save the page in the new folder there to make a copy of duplicant images, css scripts and place them in the new folder to work? Must be a way to do it and have DW know where to find the original files surely?

  Thank you

  I downloaded a test page... It turns out that the 'message' was just misleading and all the Info page has correct links. Everything is good

• Stage Builder 2.0 do not open the FXML files

  Hello!

  I have a problem with my JavaFX scene Builder v2.0 - b14.

  From time to time, the FXML cannot get Open. I have never changed the FXML manually.

  If I Rename the file, I can Open the FXML.

  Anyone have this problem or knows how to solve this?

  I've found a workaround.

  1. Copy the file to another location
  2. Then open it is possible
  3. Save it in the original location

  Think it is a bug of builder 2.0 scene.

• My vmdk files not visible from vpshere but visible from ssh console

  Hello

  I would use my dataontap virtual appliance of Netapp communities tar file.

  Their installation guide, they show just to put this on the data store tar file.

  This tar file contains the following files:

  DataONTAP.vmdk

  DataONTAP.vmx

  DataONTAP - flat hard

  DataONTAP - nvram.vmdk

  DataONTAP-nvram - flat hard

  DataONTAP - s001.vmdk by DataONTAP - s126.vmdk (126 disk files)

  DataONTAP - sim.vmdk

  DataONTAP - var.vmdk

  DataONTAP-var - flat hard

  I put this vsphere on the data store file and extract it to ssh connection on esxi with the command "tar".

  All files are now visible to PuTTY connection on esxi

  1 / but when I browse datastore, I see not all vmdk files. (missing 126 files on disk)

  2 / when I turn, this virtual machine, I have this error "DataONTAP - sim.vmdk file not found on /vmfs/volumes.../.

  But this file exist on the path specified error.

  Configuration:

  ESXi 5.1, NFS datastore.

  Stand-alone node (without cluster)

  No vcenter

  Spatial data store are free and available.

  Checksum for this tar file are OK.

  Thank you very much

  Concerning

  The files in the archive are the data files, and not the descriptor. I guess DataONTAP - sim.vmdk is the file descriptor for these files DataONTAP - sXXX.vmdk . To ensure that this is the case, please attach the DataONTAP - sim.vmdk.

  If this is the case, here are the steps that should make the usable virtual machine:

  1. load the muliextent module
     vmkload_mod multiextent
  2. Rename the virtual disk file to a temporary file name
     vmkfstools EI DataONTAP - sim.vmdk DataONTAP-sim - old.vmdk
  3. clone the virtual disk in a format supported the original file name
     vmkfstools-i DataONTAP-sim - old.vmdk DataONTAP - sim.vmdk - d thin - an ide
  4. unload the module multiextent
     multiextent vmkload_mod-u

  At this point, you should be able to turn on the virtual machine. If everything works as expected, you can delete all the temporary files of DataONTAP-sim-old * hard .

• If the Photos are not Visible after their exportation from Photos for Mac

  Export of Photos may write JPGs invisible on the disc, if the photos are exported with the option ' file name: use the title.

  If the first affected user a title to the picture, the deleted the title text, photography will have an empty title and the exported photos will be simply named ".jpg" and treated as invisible system files.  This bug can fill the disk with lots of image files, which are not visible in the Finder, unless the hidden files are made visible.

  User bikedaveca reported this bug today:

  See discussion: exported photos do not appear in the Finder

  More in this tip of the user:

  Bug: export of Images with "file name: U title" exports the files as Invisible, if the title has been deleted

  As a precaution, keep at least one printable character in the title field, when when you remove a title from a photo, so you can see, she had a given title.

  As a test, import three new pictures, for example:

  

  The first has a title, the other had a title, but removed, the third one never had a title and watch "Untitled."

  When I select and export them with ' file name: use Title ", only two photos will be displayed in the Finder.

  The problem is, that deleting a title does not remove the title, but adds an empty title. If the photos are exported with the filename ".jpg".

  

• Share photos added to the photo library via the menu are not visible on the Photos

  Hello

  I started using DxO OpticsPro 10 to process Raw files. When I used the share menu in this application to "Add photo" pictures are exported but not visible in the Photos app. I see that they are in the photo library (Show Package Contents > Masters), but they are not visible in the Photos in the Photos app. However if I use "Export to Application" instead of "Add photo" in DxO OpticsPro the Photos app opens and the image is visible.

  You can't always do and changes directly to the photo library - you must use the program of Photos to import photos - adding photos to the library has no positive effect (and may even cause problems)
