[JAVASERVERFACES_SPEC_PUBLIC-1162] Dynamically created ClientBehaviors do not call addComponentResource Created: 07/Feb/13  Updated: 13/Aug/14

Both Mojarra and MyFaces 2.1.x implementations behave the same

  • If I dynamically create UIComponents using the new Application.createComponent( context, componentType, rendererType ), I find they automatically add any dependent resources (JS/CSS) to the h:head. This is fantastic.
  • If I dynamically create ClientBehaviours using Application.createBehavior( id ), no dependent resources get added.

Am I supposed to add such resources manually? For example:

UIOutput js = new UIOutput();
js.getAttributes().put("library", "mylibrary");
js.getAttributes().put("name", "bar.js");

FacesContext context = FacesContext.getCurrentInstance();
context.getViewRoot().addComponentResource(context, js, "head");

If so, how am I supposed to know what they are? For example, if I am dynamically adding an AjaxBehavior the exact name of the JavaScript file depends on which JSF implementation I am using.

Also logged as https://issues.apache.org/jira/browse/MYFACES-3610 (but got no response, so I'm trying it as a spec issue)

The MyFaces team have indicated this may be a bug in the spec:

"the reason it does not work is because javax.faces.component.behavior.AjaxBehavior does not have @ResourceDependency attached"

Could you please discuss?

I checked javax.faces.component.behavior.AjaxBehaviour.java in the latest 2.2 snapshot...


...and it doesn't appear to be annotated there either?

Set priority to baseline ahead of JSF 2.3 triage. Priorities will be assigned accurately after this exercise.
