Hi Rudy,
from-query is only for use with variables, like this:
<bpel:from variable="BPELVariableName" part="NCName"?>
<bpel:query queryLanguage="anyURI"?>?
queryContent
</bpel:query>
</bpel:from>
Since you want to select only the result of a XPath expression, you
should use this construct:
<bpel:from expressionLanguage="anyURI"?>expression</bpel:from>
So,
<bpel:from
expressionLanguage="expressionLanguage="urn:oasis:names:tc:wsbpel:2.0:sublang:xpath2.0"?>current-dateTime()</bpel:from>
should actually work.
HTH,
Tammo
