Hello,
I have read your conversion here,
I am having a strange problem in my converter.
case 1:-
JSP
<s:textfield name="myDate"/>
classname-conversion.properties
myDate = tutorial.MyTypeConverter
case 2:-
JSP
<s:textfield name="user.myDate"/>
classname-conversion.properties
user.myDate = tutorial.MyTypeConverter
Now the problem here is that if i use case 1 i am successfully able to call
the convertToString(Map arg0, Object arg1) but in case 2 i am not able to
call convertToString(Map arg0, Object arg1).
