I am using the "Modules" feature of the Mercurial SCM plugin. Unfortunately, this feature does not work as expected.

After starting Hudson, a build will be triggered as soon as a file in the specified module was changed. After a change to a file outside this module, the plugin does not trigger a build as expected ("No changes").

However, although there is a change to a file within the module afterward, the plugin does not detect any change ("No changes"). Though, the "Last Mercurial Polling Log" shows these changed files; there are lines starting with "files:<MODULE>/..."

Restarting Hudson or reloading its configuration does work as a work-around: the next poll will trigger a build - until there is a change outside the module again.
