Bonita 7 - does it support auto-populating data values in UI?

In Bonita 6.x forms, it was easy to flow a piece of data from one UI to the next. In 7.x, I can't seem to do the same thing - please tell me if I am wrong.

For example, I want to create a simple process, where User1 enters a STRING, and User2 clicks APPROVE.

For both 6.x and 7.x I create a business data object, and then add a business variable for that object.

In 6.x I then create an instantiation form which automatically creates a text box and links that text box to the variable. I then create a 2nd form for Step1 and it automatically links that text box to the variable too, so on the 2nd form, I can see the input from the 1st form.

In 7.x, I cannot see how to automatically link a text box to a variable from a previous step. I watched a video here: https://vimeo.com/131090490 and the developer wrote a lot of code to do this very simple thing, see 10:00 to 15:00. He got the context object, found the related data object, created a variable..

In the documentation here: http://documentation.bonitasoft.com/getting-started-tutorial-0#define-bo...

It states that you must now manually add operations to store the variable results from the UI inputs. In 6.x, this was done automatically. Is this supported in 7.x also?

Is it true that in version 7 this has got harder, and there is no automatic functionality to link my data between 2 forms, I must create new variables, call out to external API, add operations manually to store the results etc?
