Resolution: Affected version:


According to the Wiki formatting help, You can link to wiki pages of another project using the following syntax.

[[sandbox:some page]]

However, it does not work if the name of the destination project includes "[" or "]" character.

For example, suppose that there is a project named "[Foo]Bar". If you want to link to wiki pages in the project, the syntax is "[[[Foo]Bar:PageName]]". However, it does not generate any link.
