Re: xpath 2.0 function bean binding camel xpath annotation

Hi again, 

Thanks for resolving this issue.

But which is the proper resultType for the very useful xpath function
distinct-values which returns a sequence of atomic values?

template.sendBody("<order
customerId=\"123\"><credit><value>10</value><value>10</value><value>12</value></credit></order>");

I can bind this with 
@XQuery("distinct-values(/order/credit/value)") String values  
and get distinctValues: 1012 

but  @XPath(distinct-values(/order/credit/value") NodeList nodes
generates as expected  
Extension function required class org.w3c.dom.NodeList; supplied value of
class net.sf.saxon.value.UntypedAtomicValue could not be converted

Would it be possible bind the result in a List<String> 
something like 
@XPath(value="distinct-values(/order/credit/value)",resultType=List.class )
List<String> distinctValues  ?

l_tsall, haven't had a chance to look at this yet, but I'll see what I can do
(in the next week hopefully)...
