I have a configuration:

class MyConfig {
    @Option
    private boolean checkbox;

    @Option
    @ActiveIf(target = "checkbox", value = "true")
    @Required
    private String firstField = null;
    
    @Option
    @ActiveIf(target = "checkbox", value = "false")
    @Required
    private String secondField = null;
}

Expected:
when checkbox = true, firstField is required, and seconField is not required.
Actual
when checkbox = true, firstField is required, and seconField is required too (I see validation error on Cloud).
Can't reproduce the same behavior with talend-component:web,
Also. Note. When initializing firstField and secondField with init value, it can be an empty string, the actual behavior becomes an expected behavior.
