How to clear a typecheck error in a loop

If your application diagram contains an arc that creates a loop between two or more components, StreamBase Studio will display a typecheck error in the Typecheck Errors View and mark the "downstream" components gray. When components are in a loop, it is unclear to StreamBase Studio which schema should be used to typecheck them, because some schemas depend on other components that have not yet processed data. When this typecheck error occurs, select one of the arcs, open its Properties view, and define the schema.

When you click off the Properties View (or click the Apply and Typecheck button near the top-right area of the Properties View), the typecheck error associated with the loop should go away. Then the arc with the schema you specified will turn blue.

If you later update a schema that participates in the loop, the typecheck error will reappear. When you click the arc StreamBase Studio provides an Update Using This Schema link in the Properties View.
