Subscribe for inherited topic with @key attribute

[tonichedgehog]

Hi, I'm have a question on subscribing on the following topic:

@nested
struct Foo {
    @key long number_1;
};

@topic
struct Bar : Foo {
    long number_2;
};

Removing the @key attribute from Foo::number_1 produces the expected result, my subscriber receives updates on the (now unkeyed) sample. With the @key attribute, my subscriber won't receive any updates. I suspect I'm missing something, essential here, and would appreciate some help pointing me in the right direction.

I'm using CycloneDDS 0.10.4, with gcc13 under MSYS2.

Thanks in advance, /T

Ok, found that this issue is already fixed on master with 7c299e45. Putting that on top of 0.10.4 solves the problem.
