Redmine

As Ruby noob I tried to understand how to implement context menus in Redmine, but currently I'm stucked with some (derivation?) problems with the view hooks and the Gantt class.

• the context menu attributes for CSS
• the context menu hooks / placeholders in show.erb
• added the context_menu_link() for each issue, which causes the following error:

Has anybody a hint how to solve this undefined method error? I already tried to let the class Gantt inherit the view listener hook class, but this lead to much more errors :(

Please try out the attached patch series.
By applying the patches, a context menu is added on each issues and gantt bars. You will be able to manipulate the issue through the context menu. I think the gantt chart will be easier to use.

This simple patch greatly improves UI/UX of gantt.
Let's deliver this feature in the next major release.

Committed in the trunk.
Mizuki ISHIKAWA, thank you for improving Redmine.

I've added some basic assertions for this feature.
