souresh khandelwal,

Sorry, forgot to also mention to add these usings: 

using Terrasoft.Web.Common;

Hello,

In Creatio, signals are event-driven triggers used to start business processes when a particular event occurs on an object, typically the addition, update, or deletion of a record. When a process contains a signal element, it essentially subscribes to a specific system event. When that event is raised, Creatio evaluates all matching subscriptions and initiates the corresponding processes.

In the case where several processes need to respond to changes on the same object but based on different business tasks (such as changes to specific fields), there are generally two architectural approaches. One is to define separate business processes, each with its own signal element. These processes start independently whenever the triggering event occurs and include internal logic to determine if they should proceed based on the field changes. The other is to design a single process with a more general signal and then route the execution flow internally, either through conditional logic or by invoking subprocesses depending on which fields were modified.

Both methods are valid and widely used in different Creatio implementations. The choice between them often depends on the nature of the business logic, the level of process reuse, and how centralized you want the control and evaluation logic to be. Having separate processes allows for more modular and decoupled logic, which can be beneficial for maintainability. A unified dispatcher-style process offers better coordination and visibility but may introduce more complexity up front.

From a performance perspective, it’s important to note that the number of signal-based triggers alone is not typically the main factor that impacts system performance. Rather, it is the overall process design, how much logic is executed, whether service calls are involved, and how efficiently process elements are structured. In environments using RabbitMQ, Creatio is more likely to offload process execution to the background automatically.

If you encounter any issues with a specific process or signal behavior, we recommend creating a support ticket via the Success Portal. Our support team will assist in analyzing and resolving the issue.

If you pass the collection from the list, you have the parent ID already since it would have to exist in the list data. You should be able to get the parent ID by just reading the child data.

Ryan Farley,

Hi Ryan, thank you for your reply!

You're right that if the certificates already had a reference to the activity, I could extract the parent ID from the collection itself.

However, in my case, the selected certificates do not yet have any relationship with the activity. The grid simply displays certificates (filtered by Account), but there’s no link between each certificate and the current activity record.

What I’m trying to do is:

• Let the user select multiple certificates from this grid,
• Then click a button to run a business process that will create the relationship between these certificates and the current activity,
• Which means I need to pass both:
  1. The selected certificate IDs,
  2. And the ID of the current activity page (which isn’t available in the certificate records).

So unfortunately, I can’t infer the parent ID from the child records — I need to explicitly pass both.

If you've come across a similar case in Freedom UI (v8.2+) and have any suggestions on how to pass both parameters to the process, I’d really appreciate it!

Thanks again
