This should work fine, unless the app.yml you are modifying is not the 
one of the currently selected bundle.

Each time a file is looked for, the bundle mechanism currently looks (in 
order of priority) in the current bundle and then in the depended-upon 
bundles. So, if config/orogen/my_project::Task.yml is in bundle A, 
bundle B depends on bundle A and has no 
config/orogen/my_project::Task.yml, then the one from A is going to be 
taken.

The confusion about loading mechanisms (and about making them more 
explicit) has been the main subject from this week's Roby meeting. See 
some points here:
