Comment: Published by Scroll Versions from space WDESIGNER and version 24.0

The Designer supports you during modeling by displaying messages for invalid actions and implementations, and giving you advice on how to fix these errors.

Info

You cannot deploy and start a process service that still has validation errors. You need to resolve them first.

Image Removed

The Designer constantly validates the contents in his editors. The validation results are displayed in the Validation panel.

The panel is available in all editors:

  • BPMN Editor
  • Execution Editor
  • Mapping Editor
  • Form Editor

If you use the panel preset, the validation panel is the second tab in the lower left corner. To return to the panel preset, go to the user preferences and click button Reset Panels.

In the Validation panel, validation findings of a service are displayed. The icon in the panel header indicates if there are any validation issues:

Everything is fine. The service is ready to be deployed.

There are validation issues. You need to resolve these issues before being able to deploy the service.

The list is sorted by error types:

  1. Image Removed Error: xUML Compiler errors
  2. Image Removed Warning: xUML Compiler warnings
  3. Image Removed Info: Designer warnings

Error Types

Three different types of validation messages are displayed:

IconError TypeDescription

Image Removed

Info

Designer warnings are labeled with the info icon. They relate to the active editor (BPMN, form, ...), and indicate that there is a problem in the model.
Despite of these messages, the project still can be compiled and deployed.

Image Removed

WarningWarnings are reported by the xUML Compiler, and refer to the implemented execution.
If the compiler reports a warning, you can deploy the service nevertheless. However, you should check the reported items in your service.

Image Removed

Error

Errors are reported by the xUML Compiler, and refer to the implemented execution. If an error is reported, deployment is not possible.
Check the mentioned parts of the service, and eliminate the cause of the error to enable model execution.

Analyzing Validation Results

The validation panel is available in all editors, and shows Designer warnings (Image Removed) of the current editor, and xUML Compiler messages (Image Removedand Image Removed) no matter where they occur. Use the information given in the validation panel to check the mentioned elements of your service model.

Using the Displayed Information

Image Removed

Validation messages describe the error, and also provide information on how to solve the problem.

Image Removed

The items in the validation panel are links. If you click on a message...

  • ...the related editor opens if not already open.
  • ...the affected element is selected on the diagram pane.
  • ...all other messages concerning this element are highlighted.

Image Removed

This also works vice versa: Click an element on the pane to highlight all messages concerning this element.

Image Removed

Regarding the execution pane, it works the same way. if you click on a message...

  • ...the affected element is selected on the execution pane.
  • ...all messages concerning this element are highlighted.
  • ...the associated BPMN element is selected on the diagram pane.

Image Removed

Same with the Mapping Editor. Click a message to highlight the affected element or object flow in the editor.

Sharing Validation Messages

Image Removed

Tip

Sometimes you want to share a validation message with another developer.

Select the displayed message (or the part you want to share) with your mouse or a double-click. Now you can copy and paste the highlighted content, e.g. to an email or a chat.
