Getting TracJsGanttPlugin to work with Trac 1.4

[seligman@…]

A user has been using Trac 1.0.4. I've tried to set up a separate web server with just Trac under CentOS7, python 2.7.5. I used "pip install Trac" and got Trac 1.4.

The user specifically requested that the TracJsGanttPlugin work. I've been fiddling with the code, and have made the changes indicated below. It's at the point where I don't get error messages when the plugin is enabled... but the plugin doesn't display anything. I tried the example:

[[TracJSGanttChart(sample=1)]]

but I just get a blank line.

Have I missed anything?

The attached files show the code changes I made to trac/env.py, tracjsgantt/tracpm.py, and tracjsgantt/tracjsgantt.py.

I should add: I know nothing about Trac or its API. I've just tried to get things to compile/interpret based on previous tickets I found on the web.
