Using Wait Close Event

The Wait close event feature in WeWeb's popup system is a powerful tool that allows your workflows to pause and wait for a popup to be closed before continuing. This creates more interactive and sequential user experiences where you can gather input from a popup and then act on that input in your original workflow.

Understanding Wait Close Event

When you open a popup using the Open popup action in a workflow, you have the option to enable Wait close event:

How it works

1. Your workflow reaches the Open popup action with Wait close event enabled
2. The popup opens for the user
3. Your workflow pauses at this point
4. The user interacts with the popup and eventually closes it
5. Your workflow resumes after the popup is closed

This is different from the default behavior, where the workflow would execute all actions immediately after the trigger.

Returning values from popups

One of the most powerful aspects of Wait close event is the ability to return values from the popup back to the original workflow.

Setting up return values

In your popup:

1. create a workflow on an element in the popup
2. add a Close this popup instance action to the workflow
3. in the data field of the action, add the information you want to return to the original workflow that opens the popup

Accessing return values

1. run your close workflow that passes data at least once
2. navigate to your original workflow that opens the popup
3. now, in any subsequent actions, you will be able to access the data returned from the popup

Common use cases

Confirmation dialogs

A classic use case is creating a confirmation dialog:

1. user clicks "Delete" button on a customer record
2. workflow opens a confirmation popup with Wait close event enabled
3. user clicks "Delete" or "Cancel" in the popup
4. popup closes with data indicating the choice and customer to delete
5. original workflow continues and proceeds with deletion using the passed customer data if the condition to delete is met
