Re: how to make freeMarker simply call toString?

Hello Dánie,

You advise works great, thank you very much for the fast response!

As for your question, I need it because I do not know the types of
variablles that arrive to my template.

My only option to display it is to follow the rule:
When I have an expression ${someObject.someFieldOrPropertOrMethod} to be
displayed
in case it returns a primitive i want it to be cast to String via it's
Wrapper class (Boolean, Float, etc)
in case it is an object that overrides Object's toString() I want it to be
displayed as a result of toString() execution.
in case it is a sequence that does not override toString() (e.g array,
list, set) I want it to be displayed as
[value1.toString,...,valueN.toString]
in case it is a Map that does not override toString I want it to be
displayed as [{key1.toString(),value1.toString()..., ]

Am I right that all I need to do, is to override BeansWrapper?

Once again, thank you very much for supporting this great project and for a
lighting fast response on Sunday :-)

Regards,
Vitaliy
