Problem

-- getting this error when running a specific map

[XOB - 106] - Data Tree Error (Illegal meta data handle)

Resolution

* the parser got "lost" and is unable to parse the flow properly

* a possible cause is that 2 objects of different types have the same name in the Mapping Flow

Ex : a step of type "Step" has the same name as a Map-Broker

* check the name of the objects in the Mapping Flow that throws the error, make the according change
