constructed, instead I was getting default one for Map mode. When I looked in
code in Component class (I extracted relavent code from Comonent class) I
noticed that actual mapping resides in ComponentType (type variable) which gets
initialized when getType() is called and is cached. This addition of caching I
think broke addTuplizer() method because type will not get recreated again and
you are stuck with the mappings that were in tuplizerImpls map variable at the
time getType() is called. <o:p></o:p></span></font></p>
