Hi all,

I have some problem with notification in LWRP.  
In this example:  
[https://github.com/optiflows-cookbooks/prosody/blob/LWRP/providers/module.rb](https://github.com/optiflows-cookbooks/prosody/blob/LWRP/providers/module.rb)  
Notifications don’t work as I expect.

For example, I want to update a configuration file when I add a module.  
Template resource is defined in an install recipe and I want to notifies it  
to take care of modification by LWRP. (I can’t use something like ".d"  
folder).  
I also want to restart service and I don’t want to duplicate service code  
(because service can be upstart / init / something else, and this code is  
manage in a different recipe). So a notification on "service[prosody]"  
define in a “service” recipe is something great… I can’t use…

I try with use\_inline\_resources and without.

Can I do something else? Or Am I wrong somewhere?

Latest chef version installed.

Thank you.

Thank you for this answer, but I don't understand what you mean by "LWRP  
resource in your recipe notify the template resource".

I'm dumb, I find the problem... "notifies" wasn't at the good place...

Thanks
