Hi,
The texo model converters can only be used with Texo generated pojos. When Texo generates pojos it also generates
separate model classes which map the pojos to the emf model (and back). The Texo model converters need this extra model
mapping code (which is generated in separate classes from the pojos).
This also explains the exception as it seems that you are trying to convert non-texo generated code.
