Subject: ValidateCompareToTag
We have used the <s:validateCompareTo> with the "comparator" attribute, we
have inserted a value binding (like comparator=#{bean.myComparator}) in the
attribute but we have received this exception:
java.lang.ClassCastException: comparator must be type interface
java.util.Comparator but is type class java.lang.String
at
org.apache.myfaces.custom.comparetovalidator.CompareToValidator.createComparator
(CompareToValidator.java:347)
at
org.apache.myfaces.custom.comparetovalidator.CompareToValidator.validate(
CompareToValidator.java:292)
even if we get a java.util.Comparator from the bean.
We have solved the problem with this patch:

if (_comparator != null)
{
ValueBinding vb = facesContext.getApplication
().createValueBinding(_comparator);
- validator.setComparator(vb.getValue(facesContext).toString());
+ validator.setComparator(vb.getValue(facesContext));
}
if (_foreignComponentName != null)
with this correction the "comparator" property receives the object instead
at first it receives a String (the cause of the later exception).
Is it correct or we have used the comparator attribute in a wrong way?
Thanks to all,
