Problem: When rebinding an MBO, Unwired WorkSpace keeps the existing parameters, so you must manually create parameters, set correct datatype for the parameters, then map the parameters to the new arguments. But if the argument is a complex (structure) type created during the rebind, Unwired WorkSpace cannot automatically generate the new complex type, and the user cannot set the new complex type to a parameter which causes parameter and argument mapping failure.
Workaround:
From the Properties view, go to the Load Parameters or Parameters tab (depending on where the problem occurred), click Refresh, then click Remap.
Unwired WorkSpace generates load parameters and automatically maps the arguments.
