A common use case for me is to have optional request parameters for which I'd like to have a default/null value. Something like the iBATIS nullValue.

@RequestParameter(default="#{true}")
Boolean myOptionalReqParameter;

Perhaps this might even allow me to use a normal boolean instead of a Boolean object.

I know I could use a xyz.page.xml file, but for simple things such as this I'd rather not.

Is this something which you think is a good idea?

Cheers,
Micke
