DateRangeSlider error not logged nor shown in CLI

Community Support

Hello all,

I have just started developping a small Bokeh app template (GitHub - hyamanieu/softfocus: Interact with a database of tidy data tables using Bokeh) and I noticed the following bug:

  • Insert a DateRangeSlider of which max and min are the same date
  • Output (client side): blank page
  • Output (server side): everything looks fine in the CLI
  • logs: no unusual message, also with the options --log-level debug or --log-level info
    It took me a while to find the origin of the problem due to the lack of logging.

Am I missing something in the log settings? How could have I found the origin of the blank page quicker?

Conditions:

  1. Tested on both Windows 10 and Ubuntu 16.04
  2. Python 3.6, tornado 4.5.2, bokeh 0.12.15
  3. Firefox

Also, thanks so much for this library! I would have hated having to learn Javascript :slight_smile: .

Cheers,

hyamanieu

Hi,

Seems like a bug, so a GH issue full full details (especially including complete code to reproduce) would be appropriate.

Thanks,

Bryan
