Solved Replace wheat to seeds

First of all, sorry for my english.

I'm trying replace the wheat to seeds(crops), but the block I have clicked don't change!

My problem:

My code:

Code:

case("CROPS"):
            age = bloco.getState().getRawData();
            if(age == 7){
                num1 = r.nextInt(101); //Chance of drop (seed), I want a better way too xD, that's terrible.
                if(num1 >= 0 && num1 <= 10)
                    semente = 0;
                else if(num1 >= 11 && num1 <= 50)
                    semente = 1;
                else if(num1 >= 51 && num1 <= 76)
                    semente = 2;
                else if(num1 > 76)
                    semente = 3;
                num2 = r.nextInt(101);
                if(num2 >= 0 && num2 <= 10) //Chance drop (wheat)
                    item = 0;
                else if(num2 >= 11 && num2 <= 75)
                    item = 1;
                else if(num2 > 76)
                    item = 2;
                event.getPlayer().getInventory().addItem(new ItemStack(Material.SEEDS, semente));
                event.getPlayer().getInventory().addItem(new ItemStack(Material.WHEAT, item));
                acao = "trigo";
                if(descontar(padrao, event, acao)) //That's removing items from the inventory, nothing important
                    bloco.setType(Material.CROPS);
            }
            break;

bloco is the block location.


What's wrong? (except my english xD)
Thank you.

 

I fixed it three hours after create this thread just adding a delay 0.5s.
Thank you anyway.
