ANY REPLY MADE TO THIS MESSAGE WILL NOT BE COLLECTED AND INSERTED IN THE BUG DATABASE. http://nagoya.apache.org/bugzilla/show_bug.cgi?id=3668 Summary: Validation error reporting Product: Tomcat 4 Version: 4.0 Release Candidate 2 Platform: All OS/Version: All Status: NEW Severity: Major Priority: Other Component: Jasper AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Jasper does not create jsp:id attributes for custom actions in the XML View of the document passed to a TagLibraryValidator. Errors found by a validator can therefore not be associated to the location of the error in the JSP page source. The spec does not require the use of the jsp:id attribute, but considering that Jasper is the Reference Implementation, I feel that it really should. Also, Jasper reports all types of validation errors (found by Jasper itself or by a validator) with a full stack trace. Considering that the stack trace does not provide any useful information in this case, and that the error message is targeted to non-programmers ("page authors"), I suggest that only the validation error message is displayed for validation errors.
