    Description

      When looking at the Vaadin dashboard, there was a partial pop-up showing an error.

      I was able to extract the following from it:

      Caused by: com.vaadin.event.ListenerMethod$MethodException: Invocation of method valueChange in org.opennms.features.vaadin.surveillanceviews.ui.dashboard.SurveillanceViewGraphComponent$1 failed.
      ...
      Caused by: java.lang.NullPointerException at java.util.regex.Matcher.getTextLength(Matcher.java:1283) at java.util.regex.Matcher.reset(Matcher.java:309) at java.util.regex.Matcher.<init>(Matcher.java:229) at java.util.regex.Pattern.matcher(Pattern.java:1093) at org.opennms.netmgt.model.ResourceId.fromString(ResourceId.java:99)
