Plone Error Reporting is a project which facilitates the submission of useful bug reports to Plone.
PloneErrorReporting replaces default_error_message and prefs_error_log_showEntry with pages that facilitate the submission of useful bug reports to Plone.
It is designed with the goal of improving the information provided by bug reporters.
To see PloneErrorReporting in action, first install the product, then create a python script called imabug in the ZMI that contains the single line
raise AttributeError, bad attribute
Now, while still authenticated, load the page http://mysite/imabug. You should see a step-by-step procedure for reporting bugs at the bottom of the error page as long as you are logged in as a Manager. Similarly, when you view bugs in the Plone error log, you will see the bug submitting procedure.
Enhancements:
- Moved the product to use its own translation domain. This fixes an issue were half-translated sentences showed up in the templates.
