Capella/Tutorials/InformationView

This page collects useful things to know about the allmighty Capella 'Information View'. Just type Ctrl-3 + Information View to open it.

The information view has 2 main purposes in Capella:

• Displays validation results
• Can be used to log arbitrary messages

In any case, a message displayed in the view can have more or one Objects, usually Model Elements, attached to it. You can see these attached objects in the context menu of a message (Related Elements is the name I think).

The view can be configured in different flavours:

• Grouped by Message severity
• Grouped by Rule ID
• Flat

The following columns are displayed:

Category: - For validation results, this is the category of the rule, as shown in the Model Validation Preference Page. - For other elements, this is the 'source' value of the underlying Diagnostic. - Special rule for EMF validation diagnostics.

• Severity: Just the severity of the marker
• Rule Set: The marker attribute IValidationConstants.TAG_PREFERENCE_EPF_FILE value
• Rule ID: The unqualified rule ID for validation results, or the diagnostic source for other markers. Special code handles EMF validation markers
• Message: The underlying marker message attribute value
• Date: The underlying marker creation time
• Resource: the value of MarkerViewUtil.PATH_ATTRIBUTE for the underlying marker

Unsolved problems:

• Special code to pretty print maker source attribute for emf validation rules. A diagnostic source is usually a plugin identifier, something more machine readable and we want something pretty-printed..
• Many of the columns are really only useful for validation results, not for arbitrary log entries
• Limited/no support to display tree structures: We start with a Diagnostic, which is a Tree, but the view linearizes it.
