Hello,

It seems that BeanUtils.populate(bean,map) cannot populate properties whose type
is "double" (or triple, or quadruple...) arrays. 

The following testCase seems to prove this :

        ... 17 more

So, i have tested this with BeanUtils 1.6.1 (but perhaps i have forgotten an
obvious thing ?).

I precise that i must absolutely use this type of functionnality (in struts)
so... i will pass my week end to patch this. I hope that i will give a patch monday.

If somebody find a workaround before monday i really appreciate if he can cc me
