Thanks for the reply martin
processUpdates isn't called during the initial rendering of the
component.. I want to leave the selection of the country separate to
the component so users can hard code it or choose how the localization
is done..
the tag would look something like this.
<foo:inputBban country="EN" />
So users are free to set the value as they like
<foo:inputBban country="#{myBean.country}" />
I could hack it and do this when setCountry(String) is called on my
component, but seems dirty.. I assume that the JSF api has provision
for this initialization of a component to configure children base on
an attribute value..
I'll keep plugging away, but any input appeciated.
