Moodle 2.0 Preview 4+ (Build: 20100710)
In the Lesson questions, in Moodle versions prior to 2.0 it is possible to use the HTML editor to format not only the question text (Page Contents) but also the Answer and Response texts.
This feature seems to have disappeared from 2.0.
Unfortunately, when upgrading from 1.9.x to 2.0, when Lesson questions' Answer and Response texts had been formatted in 1.9.x, their text is rendered as HTML tags, see attached screenshot.
To Lesson maintainer : please make the Lesson edit page look more like the Quiz edit page, including HTML editor for all editable texts (Page Contents, Answer and Response texts.
All Lesson bug reports continue to be automatically assigned to Mark Nielsen, who seems to have stopped maintaining the module quite some time ago. Please change the tracker to assign to current Lesson maintainer, whoever he is.
