Hi, I have a problem that i don't understand and i hope you can help me with.
I migrate from Tomcat 6.0.20 to Tomcat 6.0.26 and suddenly i get an exception like this: 05-Jul-2010 16:22:50 org.apache.catalina.core.StandardWrapperValve invoke SEVERE: Servlet.service() for servlet jsp threw exception javax.el.ELException: Cannot convert CREATION_TIME of type class com.docbox.tag.DocboxListColumn to class com.owt.tag.ListContent.GenericListColumn at org.apache.el.lang.ELSupport.coerceToEnum(ELSupport.java:155) at org.apache.el.lang.ELSupport.equals(ELSupport.java:110) at org.apache.el.parser.AstNotEqual.getValue(AstNotEqual.java:39) at org.apache.el.ValueExpressionImpl.getValue(ValueExpressionImpl.java:186) at org.apache.jasper.runtime.PageContextImpl.proprietaryEvaluate(PageContextImpl.java:935) at org.apache.jsp.owt.list_005fcontent_jsp._jspx_meth_c_005fwhen_005f1(list_005fcontent_jsp.java:876) at org.apache.jsp.owt.list_005fcontent_jsp._jspx_meth_c_005fchoose_005f1(list_005fcontent_jsp.java:846) at org.apache.jsp.owt.list_005fcontent_jsp._jspService(list_005fcontent_jsp.java:282) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) etc etc................................... What i don't understand is why, with the same code , Tomcat 6.0.20 didn't complain. Is the type check in ELSupport stronger now? In my case i try to compare two different enums: DocboxListColumn and GenericListColumn, but they both implement interface ListColumn. I hope you can help me with an answer Thanks in advanced Roxana Frunza
