Summary: Missing EL Coercion causes argument type mismatch
Product: Tomcat 6
Version: 6.0.14
Platform: Other
OS/Version: Windows XP
Status: NEW
Severity: major
Priority: P2
Component: Servlet & JSP API
AssignedTo: tomcat-dev@jakarta.apache.org
ReportedBy: bernhard.huemer@gmail.com
I'll attach a sample web application reproducing the error. Note that this error
only occurs when using Tomcat 6.0.x (i.e. it works with Jetty as it uses Sun's
EL RI). Moreover it doesn't matter which JSF implementation you're using to
reproduce the error (I just wanted to mention that as it's definitely no bug in
MyFaces even though the following stack trace shows a FacesException).
The exception stack trace:
javax.faces.FacesException: Exception while calling broadcast on component :
{Component-Path : [Class: javax.faces.component.UIViewRoot,ViewId: /home.jsp][
Class: javax.faces.component.html.HtmlForm,Id: j_id_jsp_923754602_1][Class:
javax.faces.component.html.HtmlCommandButton,Id: j_id_jsp_923754602_3]}
