I was trying to add the plot summary text area. But I'm getting the text area is null error when I click add button. Before it opens the scene where we add the information for the movie.
Make sure to create setPlotSummary and getPlotSummary methods in your movie class and give a private datafield of plotSummary. Also, make sure to use them in the addeditmoviecontroller class.
figured it out. I forgot to write fx:id
