JFXPanel has quite a few issues (look for JFXPanel or Swing in Jira). 
Among those is the filechooser problem. It is probably just one instance 
of the problem that a JavaFX stage cannot be modal or on top of Swing 

To work around this we have to put JFXPanels in JDialogs. Not really 
sexy: apart from the overhead in code we know today that we have to 
touch this again one day to convert the JDialog to a stage.

Regarding your problem of how to get from a node to the JFXPanel: no 
idea why you would want to do this. I have a dozen jfxpanels but never 
needed such a thing. I guess you could extend JFXPanel and add a 
reference to the fxpanel to some userdata on a node, or something like that.
