Hello! Brand new to Bokeh and not a Python person either (yet). Having said that, I have been able to create a substantial Notebook that reads and plots some fairly complex data, so starting to get the hang of things, but clearly don’t understand how the FileInput widget works. I just want to use it as a selector, then load the file on my own by retrieving the filename property from the widget. The screencap below is probably the quickest way of showing both what I want and what is not working as I expect:
As you can see, I have chosen a file, but it appears that the filename property does not persist after the widget has been run. Is that correct? Am I misusing the widget?
