[jira] Commented: (MYFACES-1197) Docs for ifMessage component

Martin Marinschek commented on MYFACES-1197:
--------------------------------------------

After some time has passed by, I'm thinking differently about this one as well.

This is my current take at this problem:

1) go with Adam's suggestion of using a custom VariableResolver which adds a new implicit object (let's call it myfacesContext), add an attribute storedComponentClientId to this implicit object.

2) create a new component which does nothing but setting the parent-client-id into this myfacesContext, e.g.: <t:storeParentComponentClientId param="#{myfacesContext.storedComponentClientId}"/>
where param is optional (by default, it's set to where the example points, you can change this to somewhere else if need be).

3) now you can use this stored-client-id in your el-expressions, and do a lot more than what ifMessage would provide.

regards,

Martin
