h:outputScript missing target error
-----------------------------------
Key: MYFACES-2584
URL: https://issues.apache.org/jira/browse/MYFACES-2584
Project: MyFaces Core
Issue Type: Bug
Components: JSR-314
Affects Versions: 2.0.0-beta-2
Reporter: Werner Punz
Priority: Minor
There is a bug in our workflow regarding the h:outputScript which prevents an
error message to be shown if the target is not present although being set.
Following behavior, make a html page with normal <head and <body tags, not
<h:head, or h:body
now set the outputScript target to head, and see that nothing happens no error
message nothing.
A black box test against mojarra revealed that mojarra places a FacesMessage
error in the message displaying
that the target could not be found.
The problem lies within our own lifecycle here, following happens, we have a
component event listener on our outputScript
which registers itself als componentResource under the target.
Now if head or body renders it gets the resources registered for the target
head or body and renders them.
But the problem now is, if there is no dedicated h:head or h:body the resources
will never get called and hence nohting happens.
I personally see two solutions to the problem, one being a head or body check
on the outputScript side, but this is inperformant.
The better idea probably would be simply to also use event mechanisms on the
head and body to save a marker somewhere (request maybe) which then later can
be checked on the outputScript component side, and if the corresponding marker
to target is not present we simply add an error...
