Re: how to make freeMarker simply call toString?

Hello,

The way it works currently is that if FreeMarker doesn't know how to
make string out of a value (an FTL sequence or FTL hash in your case),
it will check if the *wrapped* value (which is made by the
ObjectWrapper from the plain Java object) implements
TemplateScalarModel, and if it does, it will use that to generate the
text to print. So, everything is possible with a custom ObjectWrapper.

As of how to achieve this with an out-of-the box object wrapper...
BeansWrapper does this if you don't
beansWrapper.setSimpleMapWrapper(true) it, except for arrays, but the
toString output of arrays is useless anyway. However, I wouldn't
recommend setSimpleMapWrapper(false), because it mixes the method
names with the keys in the map, which can get quite confusing.

But maybe I can give a better answer (or an RFE...) if I know why is
this needed. So why?
