             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.
