IMO it's a problem of the FlowScript implementation/Rhino or what 
exactly, that defaults to Double for numbers. Can't this be handled more 
automatically by the FlowScript when calling Java? Christopher?

Thank you very much, this works like a charm :)

My concern above was another one as no "decimal" was involved. I set the 
datatype and the convertor to "float" and the binding had a problem with 
it (no FlowScript "widget.value = 0" involved!). If I remember correctly 
the binding was to an XML file and the element with its value was 

Ok, instead of asking for further help on the last issue I had a look 
into the convertors myself - they are nicely short :) And I guess I 
found the reason for this problem: The PlainFloatConvertor returned a 
BigDecimal object - I guess just a copy & paste problem. I will commit 
it now. Please confirm my observation.
