http://nagoya.apache.org/bugzilla/show_bug.cgi?id=16749 Struts EL tag handlers cannot be reused by containers Summary: Struts EL tag handlers cannot be reused by containers Product: Struts Version: 1.1 Beta 3 Platform: Sun OS/Version: Solaris Status: NEW Severity: Normal Priority: Other Component: Custom Tags AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Struts EL tags appear to be written with a pattern in which the expressions are evaluated at the start of the doStartTag method and the values of the tag attributes are overwritten with the evaluated expression values. This violates the requirement that tag handlers leave the values set by the attribute setters unchanged in case the container chooses to reuse the handler in the same context without calling the setters again. We have seen that in a page where the <html:link> and <bean:message> tags in their EL versions are being used in a <c:forEach> loop, our container (Resin 2.1.6) reuses the same tag handler without calling the setters on each loop iteration. This exposes the expected problem, as on the second and subsequent iterations, the attribute value is set to the result of the expression evaluation on the first iteration and so no longer contains an EL expression. The first iteration result is then returned for every iteration, even though the expression evaluated differently on every iteration. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
