Re: BeanManager lookup returing null !
hi felipe,
you pass in a scope-annotation as qualifier.
- it can't work, since a scope is no qualifier.
(fyi: please ask questions about cdi on the list for openwebbeans.)

Re: BeanManager lookup returing null !
Felipe,
As a side note I recommend you try Deltaspike core [1] for retrieving
beans. Alternatively you can retrieve with Omnifaces [2] too all though
since Deltaspike is composed by the makers of Weld / OWB that would be my
first bet.

[2] http://showcase.omnifaces.org/utils/Beans

Re: 2.2 stability
I can confirm that I used c:forEach erroneously. Myfaces 2.2.3 running great for me now cheers On 13 March 2014 16:27, Leonardo Uribe lu4...@gmail.com wrote: Hi @Karl I think your problem should be something different. I closed MYFACES-3869, since we have positive confirmation that the fix done works, but we need to analyze your problem and check if there is an error in MyFaces or not. We need more information than just the stack trace. MyFaces default error page gives the component tree using ErrorWriter and indicate which component has the duplicate id. There are some tricks involving programmatic component manipulation that can trigger a duplicate id exception, but not because they are correct and myfaces has a bug but because they are just invalid. In JSF 2.2, with vdl.createComponent it is possible to create programmatically added components using facelets in the right way. It is useful to use ui:debug tag to see the component tree and describe the steps involved in the exception, to help us to understand what could possible happen and how to fix it. regards, Leonardo Uribe 2014-03-13 7:19 GMT-05:00 Howard W.
