public interface IErrorReporter

An ErrorReporter acts as a container allowing a tag to gather up all errors reported by it's children and report them as a single group. Typically, there should be a single active ErrorReporter so all the errors on the page are reported in a single place. All error reporters must look at any parent tags and also the CONTAINER_ERRORS request variable for an instance of ErrorReporter before becoming the primary ErrorReporter. If another ErrorReporter is defined, the tag should return false from the isReporting() method. Otherwise, the tag may become the primary ErrorReporter. If a tag sets the CONTAINER_ERRORS request attribute, it must clear this when processing it's doEndTag() method because it will not be able to report errors after this point.

CONTAINER_ERRORS

static final String CONTAINER_ERRORS

This is a request scoped attribute name which may contain an ErrorReporter instance. If this is defined, then this is the top most error reporter and should be used to report errors.
