Core

Workflow Engine 14.1.0

Core

• Fixed an issue where subprocess parameter values were being overwritten by default values of parameters defined in the schema. Now, parameters are no longer initialized with default values when creating a subprocess. If you previously relied on this behavior, you will need to update your existing schemas or set the WorkflowRuntimeSettings.ObsoleteSubprocessParametersInitializationBehavior option totrue. This setting will only affect parameters that are not copied when using the CopySpecified, IgnoreSpecified ot IgnoreAllpolicy. When using the CopyAll policy, parameters will be copied from the parent process, making initialization unnecessary. Overwriting these parameters was a bug and not considered as breaking changes.
• The GetProcessInstancesAsync method for the MongoDB provider has been fixed. Sorting and paging now work correctly.
• The GetSchemesAsync method has been corrected, and tag lists are now generated properly. Sorting and paging for the MongoDB provider have also been fixed.
• The GetTopTimersToExecuteAsync method now throws an exception when the top argument is less than 0. The handling of this argument for the MongoDB provider has also been fixed.

Designer

• webpack has been updated to version 5.94.0.
• axios has been updated to version 1.7.4.

Workflow Engine 14.0.0

Workflow Engine Web API

Introducing a new product in the Workflow Engine ecosystem: the Workflow Engine Web API. This is a library for the ASP.NET framework that allows you to integrate a pre-built Web API into your application for managing data and processes within Workflow Engine instances. This module is easy to integrate and highly customizable, eliminating the need for routine development work to integrate Workflow Engine into your web ecosystem.

Key features:

1. RESTful Data API: Safely interact with the Workflow Engine database without the risk of internal process disruptions.
2. RPC API (Coming soon…): Remotely manage the Workflow Engine Runtime instance.
3. Permission-based Security: Fine-tune access to each API endpoint and generate claims for your users.

For more information, refer to the documentation.

Unique Indexes

• Unique indexes have been added to all database providers:
  • WorkflowGlobalParameter: Type, Name;
  • WorkflowInbox: ProcessId, IdentityId;
  • WorkflowProcessInstancePersistence: ProcessId, ParameterName;
  • WorkflowProcessTimer: ProcessId, Name.
• In MongoDB, the index for the WorkflowScheme collection (Code) is now unique.

You can update the data schema using the built-in migration mechanism for SQL databases, or manually run the update_14.0.0.js script for MongoDB. You may also choose not to use these indexes or selectively apply some of them as needed.

Potential Breaking Changes

• For MS SQL Server only: To add indexes, the field lengths for WorkflowProcessInstancePersistence.ParameterName and WorkflowProcessTimer.Name have been changed from NVARCHAR(max) to NVARCHAR(900). The migration script will automatically check if these fields contain data longer than 900 characters. If such data is found, the script will terminate with an error. In this case, you will need to manually shorten the data in these fields and rerun the migration. If you encounter difficulties during the upgrade process, please contact our support team.

Bug Fixes

• Fixed an issue where calling GetInstancedStatus on MongoDB would result in an exception.

Workflow Engine 13.3.1

Designer

• Fixed a bug that caused the import of the @optimajet/workflow-designer-react package as an ESM module to not work.
