Set the sync parameter value before every synchronization from the device application if the default value is not recognized as a sync value.
Problem: A deployed MBO contains a parameter with Filter by unselected, and the default or personalization value is not NULL, and the MBO definition contains an operator that is not equal to the user defined default value for the parameter, as this code segment illustrates:
"id > @OP["id"=""]"
If you do not set a sync parameter value from the device application, and instead expect Unwired WorkSpace to use the default value as the sync parameter value, the default value is not recognized as a sync parameter.
Solution: Set the sync parameter value before every synchronization from the device application in this scenario.
