Any idea why builders are deprecated in JavaFX 8 ?

Hi All,
Greetings!
I have worked with JavaFX 2.X. Now I am trying my hand in JavaFX 8 early access. I found that all the builders are deprecated in the jfx 8 build.
Do anybody have any idea regarding this.?
Thanks & Regards,
Sai Pradeep Dandem.

Here is the original proposal for deprecating builders:
http://mail.openjdk.java.net/pipermail/openjfx-dev/2013-March/006725.html
The relevant portions of Richard's proposal:
We made a mistake . . . our implementation has some intractable problems with respect to binary compatibility . . . this was accomplished using generics, and as it turns out, depended on two bugs in JDK 6 and JDK 7 in order to work (although we didn't know it at the time). Those bugs were fixed in JDK 8, and as a result, the builders no longer work correctly for certain cases . . . My proposal after having weighed the options is to phase out the Builders by deprecating them in 8 and removing them from the class path in 9. I believe that FXML or Lambda's or alternative languages all provide other avenues for achieving the same goals as builders but without the additional cost in byte codes or classes.Probably, when Java 8 is released, there will be some documentation that accompanies it which advises on what to use instead of builders.
My guess is that the default recommendation (at least with Java), for better or for worse would be to use FXML or just the standard procedural Java API.

  • HT204655 what i add pictures to photos  then i go to face book to add a photo and it is not there  if i restart my computer the pictures are then in photos using facebook any idea why they are not immediatly availible?

    i go to post on facebook and the piccture i have imprted to photos and i see in photos is not inmy photos to add to post in facebook
    if i restart my computer then they are there  any suggestions appreciated thank you for your time

    I would try quitting your browser and closing down Facebook rather than restarting the whole system.
    My guess would be that, if you have been using Facebook and have already accessed the Photos library, then a snapshot of the library directory (and therefore, pictures) has been taken by Facebook. That may not be updated if you then switch to Photos and import something new, or make changes there, and then switch back to Facebook.
    Restarting Safari, or whatever browser you use, and then re-visiting Facebook may, when you try to add the new picture, refresh the directory and make the change(s) visible.
    This would be my guess, and suggestion.

  • Upon entering a LV project file into VSS, all files in the project are left out. Only the project shell and settings enter VSS. Any idea why?

    Hello! It is my understanding that you need to add the individual files to the Source Code Control along with the .lvproj file.
    Here is a great deal of information on Source Code Control Practices in LabVIEW.

    You may have something as simple as a corrupt cache. Try resetting in Safe Mode and see if that fixes it. If not another thing to attempt is opening Disk Utility and Repairing Disk Permissions, do this action 2-3 times.

        Hi benzgotcha32,
    I want you to have the ability to forward any needed emails! Let's review what trouble is preventing the messages from going out. Which device do you have that's not allowing the messages to be sent? What type of email account do you have? Are you able to create a new email and have that successfully send? I look forward to hearing back from you so we can can get this matter resolved.
    Thank you,

  • My songs are cutting short, any idea why?

    my songs are cutting short, any idea why?

    Assuming you are in a region where you are allowed to redownload your past music purchases, delete the broken tracks from your iTunes library, go to the iTunes Store home page, click the Purchased link from the Quick Links section in the right-hand column, then select Music and Not on this computer. You should find download links for your tracks there.
    If you don't see them straight away it may help to close and restart iTunes.
    While downloading select Downloads in the left-hand column and make sure Allow Simultaneous Downloads is unticked.
    If the problem persists, or that facility is not yet available in your region, contact the iTunes Store support staff through the report a problem links in your account history, or via Contact Support.

  • Some photos from one day are showing up on my photo stream, and others from that same day are not. Any idea why this might be?

    Took a bunch of photos on vacation one day, and it seems like the first batch from one day are not showing up, but then all of a sudden, the ones from the second half of the day are there. They are not showing up on the photostream on my iPhone on which I took the photos, or on my iPad or in iPhoto on my computer. Any idea why this could be happening? All the other photos I took all week showed up on my Photostream.
    Is there anyway to force these photos into the photostream?
    Thanks! Any help would be appreciated!

    photo stream uploads photos from your photo app when it is connected to wifi and the photo app has been closed correctly.  That may be why your seeing photos pop up on different dates

    Under the summary tab in iTunes make sure you have Automatically Back Up This computer. If you have iCloud selected it won't back up when syncing.

  • Tabbing within my project jumps to browser fields even though preferences are set properly. Any ideas why?

    I am developing material in Captivate 8.  The option under Preferences to "restrict keyboard tabbing to slide items only" is definitely checked, but tabbing still leaves the project screen and moves into browser fields in both preview and published views.  Any ideas why this is happening?

    Did something happen to it like sliding off a table or something similar? You might want to consider making an appointment at your nearest Genius Bar and have them look at it.

  • I cannot access any songs on my iPod classic. I had around 20,000 songs on it and it now says I have 12,00o but can't access them. Any idea why this has happened?

    I cannot plug it into iTunes and reload as my MacBook crashed a few days ago and I had to get a new hard drive. Recovery software is unable to retrieve anything from the hard drive.
    All the songs were from CDs so not saved in iTunes.
    The iPod was last plugged into the MacBook one day before it crashed and it was Ok when I ejected it.
    Could it be anything to do with this? Doesn't an iPod have its own memory? Any ideas why it has happened and if their is anyway of retrieving it? Is it best to just take it into an apple shop? I am no longer covered with apple support.
    Thanks.

    When I hover over cover flow it says I have 12851 songs but when I click nothing happens.
    When I hover over artists or albums it says 'no artists/albums'.
    I can upload again from my CDs but just wondering if there is anything to do. I live abroad so all my CDs are in storage.

  • Itunes 11 sorts album under different artists name in the artist view - any idea why?

    I have just be kindly given the Maroon 5 Holiday gift via 12 days (thanks iTunes).  I also have their album 'songs about Jane' and a track from a Rihanna album which is a Maroon 5 track featuring Rihanna but issued on the Rihanna album.
    When sorted by Album the Maroon 5 albums and Rihanna track are sorted together under Maroon 5.
    However, when sorted by Artist the artist for the Album 'Songs about Jane' is being shown as Rihanna (?) but when I check the 'Get Info' data Maroon 5 are clearly shown as the Album Artist.  The holiday gift and the Rihanna track are shown under the artist Maroon 5.
    Wierd ... any ideas why and how to correct?

    Wish I did. I tried the group function but that didn't help in iTunes. The search function is the best I came up with. I can answer the question do you have susch and such artist. But I can't browse for an artist I don't remember exactly or have misspelled. Fortunately I don't think I've bought anything from iTunes that i already had. If you can't see an artist it's possible you think you don't have something you actually do have. Sorry, still hoping for a better work around or better yet a fix.
