@fujitatomoya @iuhilnehc-ynos Can you take a look?

[iuhilnehc-ynos]

I can reproduce this issue in my local windows10 env.

After calling rcl_subscription_set_content_filter with (int32_value = %0, {4} ) and waiting for content filter propagation, the first rcl_publish publishing a data that can't be filtered worked as we expected, but the message sent by the second rcl_publish should be received by the subscription, but the data can't be evaluated by the DDS_SqlFilter_evaluateOnSerialized inside RTI_CustomSqlFilter_evaluate.

@asorbini
Could you give me any suggestions?

[asorbini]

@iuhilnehc-ynos I found a small issue in the custom SQL filter code. After resolving it, the test passes consistently. I will open a PR on rmw_connextdds to fix it.

[asorbini]

Fixed by ros2/rmw_connextdds#81

[clalancette]

Closing this out, as it was fixed by the referenced PR. Feel free to reopen if it pops up again.
