Description

Bug Description When I trigger an update with viz.properties(), the window does not update.

Reproduction Steps Enter steps to reproduce the behavior:

  1. In python, run viz.properties([...], win='mywin')
  2. Open visdom in the browser
  3. Update the window with viz.properties([...], win='mywin')
  4. The property window does not update
  5. Refresh the browser. The property window contains the correct data.

Expected behavior The property window should update with new values.

Screenshots N/A

Client logs: The javascript console shows a warning:

main.js?v=47fc3afa811b358b354df09184e392e7:19 Warning: validateDOMNesting(...): <tr> cannot appear as a child of <table>. Add a <tbody> to your code to match the DOM tree generated by the browser.

However, I tested a patched version with <tbody> and it still had the update bug, even though the warning went away. So it looks like this not an issue.

I added some console.log statements inside of the render() functions, and it looks like the pane is re-rendering with the correct values. Somehow that update is not being reflected in the DOM.

Server logs: N/A

Additional context Using Chrome 78.0.3904.108 on Mac. Using visdom 0.1.8.9

Research direction
Investigate the React render function for the properties pane in main.js. The bug is likely related to how the component updates its state or how the DOM is reconciled. Check if there is a missing key prop or improper use of state. Also verify if the issue persists with newer versions of React or if it's a compatibility issue with the browser. Look at the console warning about <tr> nesting even though adding <tbody> didn't fix the update.
