TransformationException when using a two dimensional String array as parameter and return value of a service operation invoked with ws binding

[Vamsavardhana Reddy <c1...@gmail.com>]

Hi,

I have a service operation that takes String[][] as parameter and returns a
String[][].  When the operation is invoked using a webservice binding, I am
getting a TransformationException.  The stacktrace is given below.

org.apache.tuscany.sca.databinding.TransformationException:
org.apache.tuscany.sca.databinding.TransformationException: No path found

Can someone tell me if we need to worry about multidimensional arrays used
as parameters and return values in service operations invoked over ws
binding?
