Auto generated code for Inherited structure type IDL doesn't seem to work about fast-dds-gen HOT 4 CLOSED

I've tested your IDL and the generated example works for me. Indeed, changing topicKind to WITH_KEY and filling the MsgExtended structure. To make sure. Did you use the last code of fastrtpsgen? Are you setting an std::string larger than 255 characters?

Hi,
Thank you for the confirmation. I will check the following points in the test environments and inform you,
a>latest code of fastrtpsgen
b>std::string larger than 255 chars --->This i am sure i didn't. But let me confirm.

Hi, Viresh and I are work to gether. In addition to what Viresh is reporting, we made one additional change. The change is to use the type name as base type name for registering the topic. We still used the derived type message structure for publishing the messages. We made thsi change to acheive communication between derived type publisher and base type subscriber to evaluate type extensibility. Initially, when we simply use the ild file generated code, it works. But the suscriber example generated from the base type ild file doesn't receive messages from the derivce pblisher. From examples and experiments done with RTI Connext code to acheive the same(Derived Pub->Base Sub), we made the change of type name to base type name for registering the topic. After this change, as soon as the publisher recognises a subscriber, it crashes with segmentation fault.

To answer your other questions, the fastrtpsgen is latest version and the string is about 30 characters long.

Hi, Seems there copypasta error in the code for generate :: getKeyMaxCdrSerializedSize for inherited type. Look at this:

size_t NetData::position::getKeyMaxCdrSerializedSize(size_t current_alignment)
{
	size_t current_align = current_alignment;

    current_alignment += NetData::basic_msg::getKeyMaxCdrSerializedSize(current_alignment); 
    ^^^^^^^^^^ - must be current_align

    return current_align;
}
