    ${var_thrd_2}=   set variable       ${10}

    THREAD    TEST_THREAD1    False
        sleep    1
        ${var_thrd_1}=   set variable       ${2}
        Log    thread is done...
    END

    THREAD    TEST_THREAD2    False
        sleep    1
        ${var_thrd_2}=   set variable       ${11}
        Log    thread is done...
    END

    log    Variable 'var_thrd_1' before: ${var_thrd_1}
    log    Variable 'var_thrd_2' before: ${var_thrd_2}

    sleep    2
    log    Variable 'var_thrd_1' after: ${var_thrd_1}
    log    Variable 'var_thrd_2' after: ${var_thrd_2}```

The warning log come from the RobotFramework Language Server (lsp) VSCode extension because the lsp hasn't been adapted. It will not occur when running robot file from command line. I'll will modify lsp for adaptation

Hi Cuong, hm... then we need a fork of lsp, correct? Thank you, Thomas

[milanac030988]

You've already forked lsp. I've require it 3 weeks ago :)

[test-fullautomation]

Wow, I forgot. But there was no pull-request till now... I synced master with the community.

Then we also have to see that we get our forked lsp into our pipeline and releases. I create a task for this.
