Can not open FXML after a while

Even though this question has been asked long time ago and it already got an accepted answer, I want to contribute my solution to this problem because it differs from the other solutions and in addition is very simple.

This particular problem happened to me just a few mins ago and all I took to solve was:

Windows XP/7

  • Opening the Windows Taskmanager
  • Switch to the applications tab
  • Right click the SceneBuilder (named: yourFileName.fxml)
  • Select 'Maximize'

Windows 8+

  • Opening the Windows Taskmanager
  • Switch to Processes Tab
  • Click the dropbown for JavaFX Scene Builder x.x.exe
  • Find the FXML file that is not opening
  • Right-Click > Press Maximize

Description above works for Windows OS, on other OS the corresponding application managing program should do the same.

That worked for me just perfect. No copying and/or overwriting needed.


A simple workaround is:

  • copy the fxml in some other place
  • open it
  • save it to the original place(overwrite old)

That is just a workaround, but works.
It would be great if some other, better solution is found for this.
