[xdata] Fix NPE in FillableForm

Browse source 
Calling write() in FillableForm's constructor causes a NPE because
write() makes use of requiredFields which has not been set at this
time. Furthermore, write() makes use of missingRequiredFields, which
is also populated in that loop. Therefore, we have to delay the
invocation of write() until requiredFields got set.

Thanks to Dan Caseley for reporting this.
