Christian, it SHOULD be the equivalent, and for the majority of features it would be. However, in the case of pubsub-2 and I want to say views, it is not.
Shindig parses a gadget spec file and builds a metadata object including a list of features that are required in the gadget. It does not look at forced requires, and it does not walk the dependency tree. So if the <Require feature="pubsub-2"/> tag is not in the moduleprefs of the gadget, it will not be returned as part of the metadata object from shindig. That metadata object is what informs the container whether the gadget is rendered to support pubsub. To my knowledge you cannot get pubsub to work without requiring directly in the gadget spec. >-----Original Message----- >From: Christian Fischer [mailto:[email protected]] >Sent: Monday, October 08, 2012 9:42 AM >To: [email protected] >Subject: Re: OpenAjax Hub - Widget gets no connection > >Hi Erin, > >adding the feature pubsub-2 to the forced libs isn't enough? >This SHOULD be the equivalent to <Require feature="pubsub-2"/> in each >Gadget?
