On Microsoft Windows 10, the latest version of FileMaker Pro 19, the webviewercomponent uses the Microsoft Edge (Chromium) instead of the Internet Explorer (IE) engine to render web content.
This is a recent move, only available since version 19.3.1 of the product, ref. available here.
From what I can see, you are working on FileMaker Pro 19 version, but you may need to check the minor version, as if you work with 19.1.x or 19.2.x, you are still using the IE engine.
While developing any project, the platform it has to be deployed to must be clearly identified from the beginning. In the previous versions of FileMaker, we still are using by default IE 9 or IE 11 for the webviewer component. It was possible to select the IE engine by changing some Windows registry keys, or with the MBS plugin in order to automate this.
I have tested vis.js with some basic examples:
- FileMaker 17.0.7.700 - renders initial state ony, not working
- FileMaker 18.0.3.317 - renders initial state ony, not working
- FileMaker 19.3.2.206 - all works fine
If you use an older version of FileMaker, consider using an older
version of vis.js.
If you need the latest version of vis.js, upgrade your FileMaker to at
least 19.3.1.
