Re: Binding to dynamic checkbox in an array doesn't work.

The value attribute of the checkbox was 'false' even though the checked attribute was 'true' when it was checked. That seems weird, I got it resolved by setting this.value=this.checked; in the onclick action.

Thanks

  Check-box value should not be 'false', because whether you check the
box (and receive false) or not (and receive nothning)
  Try value="true". Not value="${true}" although it will work.
  Also you might want to create a hidden input to turn off unchecked
boxes: http://static.springsource.org/spring/docs/current/javadoc-api/org/springframework/web/bind/WebDataBinder.html#setFieldMarkerPrefix%28java.lang.String%29
