How to validate constraints of complex contract input

Hi
Which version of BonitaSoft are you using ? Community or Subscription.

For Subscription version, you can do this at the Front end. Usually I create a fragment that takes the values and use Javascript to validate my scenario. Hence I can put restriction on data in the Form itsef.

Hello
I am assuming that you have been successful in doing the validation as you wanted ?
If yes, then to return value in javascript, you can use $data.item.enddate
But this is how we do inside a Fragment.

Do you have a sample page that you can share in google drive. I will download it and take a look.
Please do mention which version of Bpm Studio you are using.

Regards

Hi
Here is the link to download the form

I had version 7.8.2 installed . Please see if you are able to import it.
The change is very easy. I can explain it in case you are not able to open the form.

Hello
Here is the Pic

1) Take a Container. Set the value of the container as $item.timerTask
Inside the container, take 1 text widget, 2 date widget and set the value of Text as $item.title, $item.StartDate,$item.endDate
(You have already done this part.)

2)Save the Container as Fragment. Set a Name for the Fragment. Please refer to my Pic 1. After you have already created the fragment it will be available in the form. Just take a new container. drag the Fragment inside the container. Set the value of the container as $item.timerTask (same as before)

3) Edit the fragment and add the following variables inside the Fragment.
i) item - type should be yes you must bind the variable to a variable in the page....
ii) checkDate - javascript Expression -- set the code as below

var dataDa = $data.item.startDate;
var today = new Date();
if(dataDa < today ){
alert("Error: end date should be after today");
}
//return $item.startdate;

3)Save the Fragment. Go back to the Form. click On the Fragment. set item as $item.

4) Remove validation from the form

P.S -i will share screenshots of the steps as well.
