Description:
Based on Alexander and my recent interaction with customer -

labels of components are not updated at runtime if the value is
specified as i18n value from a resource bundle.

testcase:
- create an app with a resource bundle (<f:loadBundle
basename="mybundle" var="messages"/>). the resource bundle should
contain the key "mykey"
- create a page
- add a text field to the page. specify the label of the text field as
"#{messages.mykey}"
- add a static text to the page. specify the text of the field as
"#{messages.mykey}"
- add the ability to change the language of the app (as described in
various tutorials, for example at
http://bookshelf.sfbay/jets/Rave/Tutorials/tutorials/13_internationalizatio
n/demonstrating_i18n.html

now the test:
- start the app. the label for the text field and the static text should
display the same value
- change the language of the app with the dropdown
-> result: the text in the static text changes, but the label of the
text field does not (but it should IMHO)
