Hi Richard,
thanks a lot for your code. This works also fine with me (I tried that
before) But if you switch from
<bean:write name="myObject" property="address"/>
to
<html:text name="myObject" property="address"/>
and then submit these values to antoher form, or you change it and submit it
to the same form, I get the beanutils. populate error. The output is always
fine, but the input is a mess.
I hope you also have a solution for this!
Thanks a lot
Michael
