[development] Weird behavior on #default_value

[Tao Starbow]

Probably means your #value is getting set through some other mechanism.  
FormAPI can be pretty subtle at times.  I seem to remember having a 
similar problem when I was playing around with #multistep, but I don't 
remember how I fixed it.

good luck,
