------------------------------------------
Hi Erin,
Two things:
1) Is this only a problem with custom features? Do you see this issue in the
scenario above when "myCustomFeature" is replaced with a feature built into
Shindig? If it is only a problem with a custom feature, how are you
contributing it?
2) Is this only an issue with pubsub-2 and other features within extras? For
instance, if myCustomFeature requires settitle, will has_feature('settitle')
return true?
Also, was this something you were investigating and planning on posting a patch
for? If not, I can certainly assign this JIRA to myself and have a look.

> Key: SHINDIG-1855
> URL: https://issues.apache.org/jira/browse/SHINDIG-1855
> Project: Shindig
> Issue Type: Bug
> Components: Java, Javascript
> Affects Versions: 2.5.0-beta3
> Reporter: Erin Noe-Payne
> Priority: Minor
> Labels: features
>
> When the list of gadget features is processed, only features that are
> required directly from the module prefs are taken into account - the
> dependency tree is not traversed.
> This will cause an issue for the following example:
> - MyGadget requires myCustomFeature.
> - myCustomFeature requires pubsub-2 as a dependency.
> - pubsub-2 is not added the MyGadget's features list
> - When the container checks has_feature('pubsub-2'), it will return false
> - The gadget does not properly implement pubsub-2.
