While running .fdepl files with commonapi getting an error message as the one which is mentioned below -

@swatitupat123 Can you tell me whether you are using enumeration inheritance (enumeration X extends Y {}) in your Franca IDL? I am experiencing the same issue and boiled it down to this inheritance relationship.

The problem is that when trying to access the currents enumeration width by calling getSomeIpEnumWidth(_obj) on an enumeration that has a base type this leads to a null pointer. Therefore the subsequent comparison with the base width is going to fail. The following snippet silently ignores this null pointer, but this means we wouldn't have any width in case of an inheritance relation.
