Support for Gantt chart taskContentTemplate

Content

Hello,

I am trying to create custom content within a Gantt chart task. On the OJET cookbook site I am able to put a very basic "Hello world" in using the taskContentTemplate. I have copied over the sample JSON file to my environment and attempted to do the same from VBCS. The same snippet used will not render the content within the task. The "Hello world" will not show up when inspecting the elements so it is not CSS related.

Attached are the file used in https://www.oracle.com/webfolder/technetwork/jet/jetCookbook.html?component=gantt&demo=taskDepTemplates
