Subject Context availability during method invocation / ReferenceInsertionEventHandler
Date Thu, 06 Jan 2005 15:12:40 GMT
Hi everyone,

I've searched through the JavaDocs' and source code to find a solution 
for the following problem, but I don't think there are any facilities 
for it, but maybe someone has an idea. I would like to simplify the 
following piece Velocity code:

$locale = ... user defined locale ...      // this is done while setting 
up the context

Description: $product.description.toString($locale)
Title: $product.title.toString($locale)

In which the class product has a method 'getDescription' which returens 
a home-made object of the class LocaleData. LocaleData is basically a 
map with as key a locale and as value an object, usually a string. 
Somewhat like a ResourceBundle (but not quite)

The simplified version would be like this.

$locale = ... user defined locale ...// this is done while setting up 
the context

Description: $product.description
Title: $product.title

As you can see, the whole localized stuff is gone. As far as I can see 
this can be done in two ways: Either I extend the Uberspector to 
recognize the return-type of getDescription and create the correct 
handler for it, or I intercept objects of the type LocaleData with a 
ReferenceInsertionEventHandler, and replace them for their data in the 
correct locale. Both ways though, run into dead ends. Both in the 
Uberspector as the ReferenceInsertionEventHandler the context is not 

I found a spark of hope when I saw

     * Execute method against context.
    public Object OLDexecute(Object o, InternalContextAdapter context)
        throws IllegalAccessException, MethodInvocationException
    { ..

in the GetExecutor. Unfortunatly, it seems to be deprecated, and no 
longer in use.

Anyone has any idea how to accompish automatic parsing of localized data?

Thanks in advance,
