qTask_Notification_Send and EventData - do not work once?

Hi!

Example code:
producer:

typedef enum {NO_FLAG = 0, FLAG_ENLARGE, FLAG_REDUCE, FLAG_POWER_ON, FLAG_POWER_OFF} Flags_enum;


qSM_Status_t State_Button_Release (qSM_Handler_t m)
{
	static qSTimer_t timeout;

     Flags_enum     flag[1];

	switch (m->Signal)
	{
		case QSM_SIGNAL_ENTRY:
			qSTimer_Set(&timeout, TIME_BUTTON_RELEASE);
			break;

          default:
               break;

		case QSM_SIGNAL_NONE:
			if (qSTimer_Expired(&timeout))
			{
			     m->NextState = State_Button_Wait;
               
                    switch (Button.Count)
                    {
                         case 1:
                              flag[0] = FLAG_ENLARGE;
                                                      
                              break;

                         default:
                         case 2:
                              flag[0] = FLAG_REDUCE;
                                        
                              break; 
                    }

                    qTask_Notification_Send(&Task_Set_Light, flag);
               
			}

			if (BUTTON_PRESS)
			{
	               m->NextState = State_Button_Push;
			}
			break;
	}

	return qSM_EXIT_SUCCESS;
}

consumer:

typedef struct
{
     Flags_enum     flag;
}User_Data_t;

void Set_Light_Callback (qEvent_t e)
{

     User_Data_t*   Data = (User_Data_t*)e->EventData;

     switch (Data->flag)
     {
          case FLAG_ENLARGE:
               if (PWM.PWM_Phase == 100)
               {

               }
               else
                    {
                         PWM.PWM_Phase++;
                    }
               break;

          case FLAG_REDUCE:
               if (PWM.PWM_Phase == 0)
               {

               }
               else
                    {
                         PWM.PWM_Phase--;
                         
                    }
               break;

          case FLAG_POWER_ON:
               PWM.PWM_Phase++;

               if (PWM.PWM_Phase == PWM.Save)
               {

               }
               break;

          default:
               break;
     }

}

In the function Set_Light_Callback() I get NO_FLAG (sendings FLAG_ENLARGE or FLAG_REDUCE).

If the code is changed like this:

qSM_Status_t State_Button_Release (qSM_Handler_t m)
{
	static qSTimer_t timeout;

     Flags_enum     flag[1];

	switch (m->Signal)
	{
		case QSM_SIGNAL_ENTRY:
			qSTimer_Set(&timeout, TIME_BUTTON_RELEASE);
			break;

          default:
               //break;    <- comment

		case QSM_SIGNAL_NONE:
              <....>

         }

}

In this case, everything is fine, but the Set_Light_Callback() function is called 2 times. Is this a bug?

//Sorry for the english language

hi @dashkova ,
State_Button_Release only changes if the BUTTON_PRESS it's true, otherwise, the state remains, and later notifications can be sent to Task_Set_Light,

Hi!
Hmmm...
Fixed the code (data via argument):

int main (void)
{
UserData_t       Data;

qOS_Add_StateMachineTask(<...>, &Data )

It works!
