UML22 — Section: 11.3.4

Association fromAction:Action[1] missing the specialization or subsets statement shown in fig. 159. Add OCL statements to constraints. Fig. 161 shows the association +action between i2:ActionInputPin and s1:ReadSetAction and between i4:ActionInputPin and s2:ReadSetAction but this is not an association defined for ActionInputPin in the text or shown on fig. 159. Either correct +action association to +fromAction or add +action as an association of ActionInputPin. I may be totally incorrect but shouldn't there be some link or association from the classifier bar:Signal?

See revised text. The rest is duplicate with 6452.
