Description

In my application, whenever I have an error deeper than the action level ( i.e. an exception thrown by one of my DAOs, Managers, or JDBC calls ), instead of the seeing the actual error, as rendered by error.ftl ( i have devMode enabled ),

I get the following error from FreeMarker trying to render the template :

HTTP Status 500 - Unable to show problem report: freemarker.core.NonStringException: Error on line 45, column 27 in org/apache/struts2/dispatcher/error.ftl Expecting a string, date or number here, Expression msg is instead a freemarker.ext.beans.SimpleMethodModel

type Status report

message Unable to show problem report: freemarker.core.NonStringException: Error on line 45, column 27 in org/apache/struts2/dispatcher/error.ftl Expecting a string, date or number here, Expression msg is instead a freemarker.ext.beans.SimpleMethodModel

description The server encountered an internal error (Unable to show problem report: freemarker.core.NonStringException: Error on line 45, column 27 in org/apache/struts2/dispatcher/error.ftl Expecting a string, date or number here, Expression msg is instead a freemarker.ext.beans.SimpleMethodModel) that prevented it from fulfilling this request.

The full stack trace is :
