Hi,
try changing "ID" to "Id". The thing is that following JavaBeans specification,
only the first letter of the variable has to be capitalized.
For example:
If your bean has a variable "question", the setter method will be "setQuestion",
the getter method will be "getQuestion", i.e. the first letter of your variable
"question" is turned into a capital letter
So, following the same rules, if your variable is "id", the set and get methods
must be "setId" and "getId".
