Device Synchronization Returns no Data

Problem: Improper syntax in generated code calls causes device synchronization to return no data.

Explanation: This may originate from a misconception about the syntax of generated code calls. In this code example, the deployment_unit file, customer_list_unit.xml, used to autogenerate the class objects, contains this section: 

<synchronization-parameter name="city" type="string?"/>

This indicates that the class object created from the XML requires "city" to be specified prior to syncing with the object.

Solution: Research the mobile business object (MBO) design in Eclipse.

  1. Make sure that the synchronization parameter is mapped to an attribute:
    1. In MBO properties, from the Synchronization tab, select a sync parameter.
    2. Select an attribute for the "map to" column.
  2. After making the change, regenerate the classes, and resynchronize the MBO on the device.
