#<NoMethodError: undefined method `layout_scene' for #<Java::JavafxStage::Stage:0x5eea82fc>> about jrubyfx HOT 5 CLOSED

huh, thats odd. are you sure all the files in core_ext are in the jar? Only other suggestion is why are you calling stage.layout_scene(500, 250, :black) ? The with() function makes it implicit: layout_scene(500, 250, :black)

Thats actually just code I copied from one of the samples. Except that when I got this error the first few times, I changed it to an explicit call on stage to see if that made a difference which it didn't. Same error. But yeah, definitely checked and the files are in there, including stage.rb where that method is defined.

yea I know where it came from, I ported that sample to JRubyFX 😀

hmm, put a puts "hey I was included!" in stage.rb and make sure its called. alternatively, puts file on line 232 of dsl.rb and make sure all extensions are loaded.

Hah. Nice work on that, I always thought that was a pretty demo from GroovyFX, ScalaFX, etc. Was happy to see JRubyFX in those brilliant gradients.

So after all our tail-chasing earlier, lol, finally got a chance to look back at this. I added puts "hey I was included!" at the bottom of stage.rb, then for good measure, also went into dsl.rb and added it like this:

    def self.load_dsl
      rt = "#{File.dirname(__FILE__)}/core_ext"
      Dir.glob("#{rt}/*.rb") do |file|
        puts "Before require"                                # See if the block is running at all
        require file
        puts file                                                     # See if the require itself is messing up
      end

Rebuilding the jar and then just using it to run the file works fine, and we get a bunch of output like:

 java -jar jruby-log.jar hello.rb 
Before require
file:/home/eric/projects/jrubyfx_projects/jrubyfx_web/jruby-log.jar!/jrubyfx/core_ext/radial_gradient.rb
Before require
file:/home/eric/projects/jrubyfx_projects/jrubyfx_web/jruby-log.jar!/jrubyfx/core_ext/drag_event.rb
Before require
...
file:/home/eric/projects/jrubyfx_projects/jrubyfx_web/jruby-log.jar!/jrubyfx/core_ext/node.rb
Before require
hey I was included!
...

But when I try using the javafx Launcher again, back to that error:

Exception running Application:

Gotta get some sleep here, but wanted to get this recorded.

BTW, that error was the only output. Nothing from our puts statements.
