Could not render BurndownChart

Reported by: stanly.lau@… Owned by: Joachim Hoessler
Priority: normal Component: EstimationToolsPlugin
Severity: critical Keywords:
Cc: Trac Release: 0.11


Hi, I had installed EstimationToolsPlugin from and XmlRpcPlugin from on my Trac 11.2.1. However when I tried to insert the sample macro indicated in the website

BurndownChart(milestone=Sprint 1, startdate=2008-01-01)?

I had the following error:

Error: Macro BurndownChart(milestone=Product Backlog, startdate=2008-01-01) failed
unrecognized token: "#"

I had created a milestone 'Sprint 1' with some tickets tagged to it. All the plugins installed are enabled. May I know what could be the problem?

Thank you, Stanly

Forgot to code block the macro in the description. Here it is:

[[BurndownChart(milestone=Sprint 1, startdate=2008-01-01)]]

Hm, I've never seen that error message. Could you enable logging and check if that provides some more information on what goes wrong?

Hi, here's the debug logging turned on.

Resolution: fixed
Status: newclosed

Doh, I think I found the bug: it's not a bug in the plugin, but in its documentation. In the trac.ini file you are not allowed to !add comments at the end of a line, they have to be on a new line instead. So in your trac.ini, I guess you have

estimation_field = estimatedhours   # if you want to use another field than estimatedhours 

but it should be

# if you want to use another field than estimatedhours
estimation_field = estimatedhours    

I fixed that in the installation docs on the wiki page.
