http://issues.apache.org/bugzilla/show_bug.cgi?id=37918 Summary: EL cannot find valid getter from object when using some inheritance Product: Tomcat 5 Version: 5.5.12 Platform: PC OS/Version: Windows XP Status: NEW Severity: normal Priority: P2 Component: Jasper AssignedTo: tomcat-dev@jakarta.apache.org ReportedBy: [EMAIL PROTECTED] Is just have found an strange error. I don't know how is the EL built inside Tomcat, but here it is... This is the stacktrace: javax.servlet.jsp.el.ELException: Unable to find a value for "porOrden" in object of class "net.sargue.escuder.webapp.persistencia.CategoriasServiciosDB" using operator "." at org.apache.commons.el.Logger.logError(Logger.java:481) at org.apache.commons.el.Logger.logError(Logger.java:498) at org.apache.commons.el.Logger.logError(Logger.java:611) at org.apache.commons.el.ArraySuffix.evaluate(ArraySuffix.java:340) at org.apache.commons.el.ComplexValue.evaluate(ComplexValue.java:145) at org.apache.commons.el.ExpressionEvaluatorImpl.evaluate(ExpressionEvaluatorImpl.java:263) at org.apache.commons.el.ExpressionEvaluatorImpl.evaluate(ExpressionEvaluatorImpl.java:190) at org.apache.jasper.runtime.PageContextImpl.proprietaryEvaluate(PageContextImpl.java:922) at org.apache.jsp.ges.stats.resumenServicios_jsp._jspx_meth_c_forEach_3(org.apache.jsp.ges.stats.resumenServicios_jsp:565) at org.apache.jsp.ges.stats.resumenServicios_jsp._jspService(org.apache.jsp.ges.stats.resumenServicios_jsp:170) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:97) at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:322) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264) at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.apache.catalina.core.ApplicationDispatcher.invoke(ApplicationDispatcher.java:672) at org.apache.catalina.core.ApplicationDispatcher.processRequest(ApplicationDispatcher.java:463) at org.apache.catalina.core.ApplicationDispatcher.doForward(ApplicationDispatcher.java:398) at org.apache.catalina.core.ApplicationDispatcher.forward(ApplicationDispatcher.java:301) at net.sargue.escuder.webapp.controladores.BaseServlet.forward(BaseServlet.java:61) at net.sargue.escuder.webapp.controladores.KStats.doGetAction(KStats.java:78) at net.sargue.escuder.webapp.controladores.BaseServlet.doGet(BaseServlet.java:22) at javax.servlet.http.HttpServlet.service(HttpServlet.java:689) at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at net.sargue.escuder.webapp.controladores.KLogin.doFilter(KLogin.java:38) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:178) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:126) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:541) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:868) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:663) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:80) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:684) at java.lang.Thread.run(Thread.java:595) The class net.sargue.escuder.webapp.persistencia.CategoriasServiciosDB has a getPorOrden() method inherited. It looks like: public class CategoriasServiciosDB extends CachedLocalSortableEntityDB<CategoriaServicios> {...} And the superclass looks like: public abstract class CachedLocalSortableEntityDB<E extends SortableLocalEntity> extends CachedLocalEntityDB<E> { public SortedSet<E> getPorOrden() {...} } So it should work. The strange part is, if I redefine the method on the derived class just as this: public SortedSet<CategoriaServicios> getPorOrden() { return super.getPorOrden(); } It works. I'm using it as a workaround, but I think it's probably a bug in the EL resolver? -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
