Subject Re: [BeanUtils] BeanUtils.populate is not working
Date Wed, 03 Nov 2004 00:07:07 GMT
I think I unnderstood what happened.

Inside bean utils (I don't know why) the timesatamp value become a string.
And Bean util (I don't know why either) can set a string to a timestamp
property, but not to a date property.
