K2 Workflow Event Wizards: Configuring the Start Rule of an activity

When working with K2 Workflow components, it is often necessary to specify when a K2 Workflow component may execute. We can control the time of execution, by configuring what is called a “Start Rule”.

In today’s blog, this is exactly what I’ll show you how to do. First we’ll need a Workflow Activity. A Workflow Activity is a container for K2 Workflow components. Drag-and-Drop an event from the toolbox onto the K2 Workflow Designer, the event will automatically be placed inside a Workflow Activity.

K2 SmartForms Rule Interaction

K2 SmartForms Rule Interaction

When working with any K2 SmartForm project, you sometimes find that pieces of functionality mimic another or call the same procedures.

In K2 you can’t physically copy and paste rules, but you can execute one rule from within another rule.

This is really convenient when you have to execute the exact same set of conditions / functions from multiple control interactions, and it also makes later changes a lot simpler since the change needs to be done in only one place. When you need something extra to be done that the “base rule” doesn’t take care of you can just piggy-back it before or after the referenced rule as needed.

Registering a new SQL Server K2 Service Instance and generating associated K2 SmartObjects

The K2 SmartObjects available in the K2 Designer are usually associated with Data Sources registered via the SmartObject Services Tester.

In this blog I’d like to show you not only how to register a new SQL Server Service instance using the K2 SmartObject Services Tester, but generate the associated K2 SmartObjects as well.

For the purposes of this blog I have created a new Database in SQL Server called CompanyDatabase and created three associated tables i.e. Customers, Products and Invoices.
