The party leaders incited Trump as a means to get media attention for their convention. It was not a popular choice and a lot of the delegates and party members were asking the invitation be revoked because it can send confusing signals to the rest of the world that aren’t familiar with the party. Since the leaders refused to revoke the invitation the members took it upon themselves to make it clear they don’t support Trump hence all the booing/heckling. There were also apparently a lot of rubber chickens that were confiscated by secret service that were going to be used as noise makers.
