haveServicesChanged

A Workflow Engine function that detects whether the Services for a Situation have changed (added to or removed from). If there are no changes, the action returns false. If there are either additions or deletions, the action returns true. The list of additions and removals is written to the workflowContext under the servicesAdded and servicesRemoved keys.

This function should be in a Situation action-driven workflow engine and should be preceded by the sigActonFilter action with the actionType argument set to include “Changed Situation Services”.

This function is available as a feature of the Add-ons v2.2 download and later.

This function is available for Situation workflows only.

Arguments

Workflow Engine function haveServicesChanged has no arguments.

Example

To detect if a Situation’s services were altered, a SigAction-based engine would contain a workflow with the following actions:

  • sigActionFilter

    • actionTypes : [ “Changed Situation Services” ]

  • haveServicesChanged

If the Situation services changed (via the UI, APIs or standard workflow), the workflowContext would contain these details:

{
    "servicesRemoved": [
        "Manager2"
    ],
    "servicesAdded": [
        "Manager"
    ]
}

Here Services were both added and removed.
