Adam Winer commented on MYFACES-1197:
-------------------------------------
Mike Y: that is a tough problem: you don't have the current UIComponent to
find from - which is unfortunate. If the target UIComponent had a "binding"
associated, then life would be simple:
<h:inputText binding="#{bean.someComponent}"/>
<h:outputText rendered="#{myFaces.messagePresent[bean.someComponent]}"/>
Mike K.: it would be a very good thing for MyFaces to have a single
VariableResolver that installs a custom "myFaces" object (and only that) - and
with that done, no, there really wouldn't be much in the way of interactions
with other resolvers to worry about, or any safety issues. Then, *within* that
object, you could have any sort of map-property-as-function objects, etc., and
add other things that really belong in the EL instead of as components (a list
of SelectItems for countries comes to mind).
