Display Processes by Process Model with Status Icons

Tip:  Interface patterns give you an opportunity to explore different interface designs. Be sure to check out How to Adapt a Pattern for Your Application.

Goal

Use an interface to display information about instances of a specific process model.

This design pattern is not recommended for offline interfaces because reflecting immediate changes in an interface based on user interaction requires a connection to the server.

This scenario demonstrates:

  • How to use a!queryProcessAnalytics() to query process data
  • How to display process report data in a grid
  • How to use the process report's configured formatting to customize display
  • How to us a!forEach() to dynamically create a grid's columns

Setup

For this recipe, you'll need a constant pointing to a process report and a process model that has been at least started a few times. If you don't have a process model, you can follow the Process Modeling Tutorial. Once you have some processes, you can follow these steps to create a process report with the default columns and associate it with a constant:

  1. In the Build view of your application, click NEW > Process Report.
  2. Select Create from scratch.
  3. Name the report Processes for Process Model A.
  4. Under Report Type, select Process.
  5. Under Context Type, select Processes by process model.
  6. Specify a folder to contain the report, and then click Create.
  7. Open the process report in a new tab. You will see the Choose Process Models dialog open.
  8. In the Choose Process Models dialog, select the desired process model, and then click OK.

The main expression uses two supporting constants, so let's create them first.

  • UC_PROCESSES_FOR_PM_REPORT: Constant of type Document whose value is Processes for Process Model A.
  • UC_PROCESS_MODEL: Constant of type Process Model whose value is the process you created.

            ) ),
            index(fv!row, fv!item.field)
        )
      )
    ),
    rowHeader: 1,
    pageSize: 20
  )
)

Test It Out

  1. Sort and (if you have enough processes) page your grid
  2. In another window or tab, complete a process and then refresh your interface to see the status change

Notable Implementation Details

  • This example shows how to specially handle one kind of formatting, but the same pattern can be applied to provide an interface interpretation of other process report configurations.
