> Unable to create a custom validator inheriting IntRangeFieldValidator
> ---------------------------------------------------------------------
>
> Key: WW-4167
> URL: https://issues.apache.org/jira/browse/WW-4167
> Project: Struts 2
> Issue Type: Bug
> Components: XML Validators
> Affects Versions: 2.3.15.1
> Environment: Windows 7 64bit, Java Runtime Environment 7, Tomcat 7
> CentOS 5 32bit, Java Runtime Environment 6, Tomcat 6
> Reporter: recyclebin5385
> Assignee: Lukasz Lenart
> Priority: Minor
> Fix For: 2.3.18
>
>
> I created a custom struts validator class which inherits
> IntRangeFieldValidator, but a runtime error occurs when checking a input
> value with the validator.
> When I examined the internal data with a debugger, properties "min" and "max"
> of the custom class were stored as Strings, not Integers.
> Parameters "min" and "max" are read from [ActionName]-validation.xml,
> converted to Integers, and set to the properties of a validator instance
> using OGNL.
> But the conversion to Integers is skipped for a derived class of
> IntRangeFieldValidator.
> The cause seems to be a bug in OGNL library. See
> https://issues.apache.org/jira/browse/OGNL-238.
> Methods setMin and setMax's argument types are the type parameter T in
> AbstractRangeValidator<T>.
> OGNL library handles the type parameter for a directly derived class of a
> generic class, but not for an indirectly derived one.
> A workaround is to override all getters and setters with a parameterized
> class in a custom validator class without using a type parameter.
> That is, when I define a class which extends IntRangeFieldValidator, I have
> to also define methods "Integer getMin()", "void setMin(Integer min)",
> "Integer getMax()" and "void setMax(Integer max)" in the class.
