Hi,

I guess the problem is the specificity of view parameter processing.
When validating a view parameter for an initial GET request, the
<f:loadBundle/> is not yet available, so we got an empty value of
requiredMessage attribute at that moment. Is this true? If this is
true, it seems that <f:loadBundle> cannot be used for requiredMessage
attribute of <f:viewParam>.
