(FIX) Messages not updating when using 'js' module

I'm getting a similar error when using the Overlay module:

Fatal error: Call to undefined function current_path() in .../modules/overlay/overlay.module on line 131

Your recommended fix works for me but I'm not sure if the js module is the right place for a fix. If you use the default bootstrap phase DRUPAL_BOOTSTRAP_DATABASE there is no need to include path.inc. But Chatblock uses DRUPAL_BOOTSTRAP_LANGUAGE where path.inc is needed for some modules. So I think it would be better to fix this in Chatblock. This could be done by adding 'path' to the 'includes'-Parameter of the js callback.

So this seems to be a very particular error which, in addition, I rather see fixed in JS. Or try whether an older release of JS works - the module had some changes in the last time, I guess. Just a guess.

The JS module gives you the option to change the bootstrap level. If you don't use this option everything is fine with JS. So I think it's up to the calling module to specify the needed includes, because the JS module has no option to find out which includes are really needed by the calling (chatblock) module if another bootstrap level is used.

The JS documentation says:

... modules may also specify another bootstrap level than the default DRUPAL_BOOTSTRAP_DATABASE,
and additionally required includes files and module dependencies to load.

So I'm unsure if there is a possibility to fix this in the JS module.
