You can delete the model elements from the model search view in IBM Architecture Room LIVE!
Procedure
Deleting a model element from the search window
- You can select a model element from the search result and click the delete option to remove the
model element. All instances of the shape across all whiteboards are deleted, and the list of search
results reflect the change in the number of instances that are found for the element.
- If a class referred in a lifeline is deleted, the reference to the deleted model element in the
lifeline is marked in red to indicate that it is an invalid reference as the model element is no
longer available.
- If an operation referred by a Message is deleted, then that Message must be marked in red to
indicate that it has an invalid reference.
To correct the error state correct, that is to correct the red mark in the diagram, you must
assign a new class to the lifeline or a new operation to the message. The red error marks get reset
and the diagram and its elements become valid.
