x:inputCalandar display issues when default fields are changed

[mfaine]

Myfaces 1.0.9

I set the default value for an x:inputCalandar before the page loads if
someone changes either the day of the week or the year and leaves them
blank,   then clicks the popup button.  The display of the calandar goes all
horizontal and will then display NaN for the year.  

Any help would be appreciated.

Thanks,
