If caching is on, and a template has been previously cached due to a #parse or
#include directive, subsequently using the other directive will cause a
ClassCastException and fail.
Example: if I have two templates, the first one loaded includes the line:
#include( "include/header.vtl" )
and the second one the line:
#parse( "include/header.vtl" )
When the second page is viewed, a ClassCastException is thrown with an error in
the log like:
[error] #parse() : arg = include/header.vtl. Exception :
A solution might be to include the resourceType as part of the key when
caching/retrieving the resource, within the getResource() method of the
org.apache.velocity.runtime.resource.ResourceManagerImpl class. Alternatively
seperate caches could be used for the different types of Resource.
