AXEvent : ax_event_handler_declare always returns the same declaration id

[polodroid74]

Issue description

When trying to declare multiple events, calls to ax_event_handler_declare() always returns the same declaration id. Here is a code snippet to illustrate where the problem occurs :

int tar::setupFloodStateDeclaration(std::unique_ptr<tar::EventData> &event_data){ //This function is called with several EventData structures
    AXEventKeyValueSet *key_value_set = ax_event_key_value_set_new();
    GError *error = nullptr;
    const std::string flood_str = "Flood"+std::to_string(event_data -> flood_level);
    gboolean state_value = false;
    ax_event_key_value_set_add_key_value(key_value_set,
                                         flood_str.c_str(),
                                         NULL,
                                         &state_value,
                                         AX_VALUE_TYPE_BOOL,
                                         &error);

    ax_event_key_value_set_mark_as_data(key_value_set,
                                        flood_str.c_str(),
                                        NULL,
                                        &error);
    //Declare event
    ax_event_handler_declare(event_data -> event_handler,
                             key_value_set,
                             false, /* Indicates a state full declaration. */
                             &(event_data -> event_id), <------------------------------ Here we will always have 1.
                             (AXDeclarationCompleteCallback)declarationComplete,
                             event_data.get(),
                             &error);
    ax_event_key_value_set_free(key_value_set);

Hi @polodroid74 , thanks for reaching out, we'll get back to you when we had time to look in to this.

A quick look in the code, the id is expected to be stepped.

It's important to create only one AxEventHandler and reuse it throughout the program, see for example subscribe_to_events. The same should go for declaring events. Could this be it?

Yes this is it. Thanks a lot !
