UML/SysML: Cameo Simulation Toolkit 19SP3: GOTCHA/TIP: ConstraintBlock constraints: Not every available constraint language can handle Enumeration literals (if in doubt choose 'English')
UML: Cameo Simulation Toolkit 19SP3: GOTCHA: CreateObjectAction ignores an Artifact as 'classifier' even though Artifact is a Classifier
GOTCHA: UML/SysML: Cameo Simulation Toolkit 19SP3: A [true] or [false] guard on an ActivityEdge MUST be a LiteralBoolean, not just characters typed in, or the evaluation may give unexpected or ill-defined results
UML/SysML: Cameo Simulation Toolkit 19SP3: A parent Activity with a DecisionNode that uses a Activity as a decisionInput Behavior terminates immediately after the decisionInput terminates (but OpaqueBehavior works)
UML/SysML: Cameo Simulation Toolkit 19SP3: GOTCHA: Will not evaluate a guard using a token from a decisionInputFlow UNLESS a decisionInput Behaviour is explicitly defined (but Alf does)
Webel: SysML: DO NOT sacrifice modelling naming conventions for the mere sake of carrying organisation-specific names! Instead use tagged values of custom stereotypes as metadata to carry alternative names in parallel with systematic model element names.
Sample problems and example diagrams in graphical language specifications are NOT necessarily indications of how one should model on a real-world project! They often just serve to demonstrate a particular aspect of the specified language.
UML/SysML: If you have a Boolean "state flag" attribute corresponding to a State you MUST set it on an 'entry' of the State, not on the 'effect' of a Transition into the State (otherwise with multiple incoming Transitions it could be WET and breaks SSoT).
UML/SysML: When you use an AddStructuralFeatureValueAction to set one end of a bi-directional Association it also sets the other end.
BUG: Cameo Simulation Toolkit 19SP3: StateMachine: Crashes with an irrelevant "memory error" report if you fire a signal Trigger during execution of an 'entry' Activity with a timer
