Hi All,

I am trying to generate Employee MBO from webservice
datasource.

My webservice is returning a simple Employee instance with
following fields

int empId;
String empFName;
String empLName;
int deptId;

First I am trying to add Attributes by dragging the
getEmployee webservice method which returns an employee by
taking empId as input.
During this process I am trying to see the Preview of this
operation.
I found that it is calling the webservice method correctly
and web service is returning an employee also but
MBO generation wizard failed with following error.

Execution failed: The data type integer does not support
conversion for empty string.

It looks like it is trying to convert null to int for empId.

Can you please help me to solve this issue.
