             Summary: TextMarker: Rule matching on annotations with different boundary visibility
                 Key: UIMA-2761
                 URL: https://issues.apache.org/jira/browse/UIMA-2761
             Project: UIMA
          Issue Type: Bug
          Components: TextMarker
            Reporter: Peter Klügl
            Assignee: Peter Klügl


There are actually two problems with annotations with different boundary visibility. Annotations
like Name (covered text "Peter ") where (with default settings) the begin anchor is visible,
but the end anchor is invisible (because of the space).

The first problem is that the direction in which the rule elements match using dynamic anchoring
is important, if any results are returned. An example: The rule "CW Name;" matches differently
depending on the rule element which starts the match.

The second problem is that there is additionally a bug in finding the next matching position,
if the current match ends with something invisible.
