I have a template with a pojo in the context with a method called
thumbResource(String, String)
When I parse the template with an null for the second parameter
$myPojo.thumbResource(main, null)
it throws the exception.
Debugging it in eclipse is just says :
java.lang.IllegalArgumentException: wrong number of arguments
It is thrown in the method.invoke method below ASTMethod.java
try
{
/*
* get the returned object. It may be null, and that is
* valid for something declared with a void return type.
* Since the caller is expecting something to be returned,
* as long as things are peachy, we can return an empty
* String so ASTReference() correctly figures out that
* all is well.
*/
Object obj = method.invoke(o, params);
if (obj == null)
{
if( method.getReturnType() == Void.TYPE)
{
return "";
}
}
return obj;
}
catch( InvocationTargetException ite )
{
return handleInvocationException(o, context,
ite.getTargetException());
}
/** Can also be thrown by method invocation **/
catch( IllegalArgumentException t )
{
return handleInvocationException(o, context, t);
}
I will try to debug it further.
Thanks
