Hello all, I'm having an issue with my grails app, I have the Daily Sheet domain class with hasMany relationships, there is the DailySheet code:

class DailySheet extends Sheet {
    String status = 'Nuevo'
    Date startDate
    Date endingDate
    String comment = ""

    static hasMany = [ analyzes:DailySheetAnalysis,
                       tasks:Task,
                       machines:MachineDailySheet,
                       attendances:Attendance,
                       externalEvents:ExternalEvent]
    static belongsTo = [workplace:Workplace]

    static constraints = {
        endingDate nullable:true
        comment nullable:true,blank:true
        status inList:['En proceso','Aceptado','Rechazado']
    }

    static mapping = {
        comment sqlType:'text'
    }
}

And there the Task code:

class Task {
    String description
    Date beginDate
    Date endDate

    static belongsTo = [sheet:DailySheet]
}

I save a DailySheet with 5 task and it works correctly, but I when modify the object and send it from the frontend, the DailySheet with 3 task (I removed 2 task in the frontend) the Tasks are not deleted in the database, there still the 5 tasks. The frontend is developed in VueJS and send the object as JSON, there aren't problem:

const { status, data } = await thanatosApi.post('/dailySheet',{ dailySheet:dailySheet.value })

if(status === 200){
    Notify.create({
    timeout:1500,
    message:'Registro guardado, subiendo fotos...',
    actions:[{icon:'close',color:'white'}],
    type:'positive'})
}
