Before Create/UpdateTask you can call "User_AlreadyExist" action and based on true/false from AlreadyExist you can give some feedback message like "User Already exist"..

Let me know if have any concern

hai pratiksha,

    You can set unique index for your attribute, so that you can't able to add same name again. When you try to add same name it showing an error.

Hi Pratiksha,

You can also use other way like you can check user is exits or not on "onChange" property of input box. You can use ajax to check if user exit or not. So, that you can check it on the page itself at once.

thanks....

Hello, 

To check if user exist the best approach is make a query to check if user extis:

You need to add 2 conditions:

1. User.username = Username (to check if username already exists)

2. User.id <> UserId (to check if is a different record, because if you are editing the ID will be the same)

After call the entity check if is empty: If is not empty is beacuse exists a record with the same username on DB and you need to exit the flow and show a error.

Hope this can help you.

Firstly I Create a "User_alreadyExist server" action than in that action I developed the below logic.

Is it correct for avoiding the addition of users with the same name.

Please suggest me

Hi 

Please take some decision based on the User_AlreadyExist action.like

If (User_AlreadyExist=true){

Alert("User already exist")

}else{

Call CreateOrUpdateTask

}

Can you share your module (oml file) to give a look on the app?
