[stringtemplate-interest] Re: stringtemplate-interest Digest, Vol 17, Issue 7

[Harry Karadimas]

I'm not sure but I think your "HashMap" may be confusing st as it is

HashMap<String,Object>

and not

HashMap<Object,Object>

so it is not an exact instance of "HashMap", which is what st expects. 
However I'm no generics expert.
