Author: jverhaeg(a)redhat.com Date: 2008-06-10 18:16:01 -0400 (Tue, 10 Jun 2008) New Revision: 260 Added: trunk/dna-common/src/main/java/org/jboss/dna/common/collection/Problems.java trunk/dna-common/src/main/java/org/jboss/dna/common/collection/SimpleProblems.java Removed: trunk/dna-common/src/main/java/org/jboss/dna/common/collection/Problems.java trunk/dna-common/src/main/java/org/jboss/dna/common/monitor/NullProgressMonitor.java Modified: trunk/dna-common/src/main/java/org/jboss/dna/common/collection/UnmodifiableProperties.java trunk/dna-common/src/main/java/org/jboss/dna/common/monitor/ProgressMonitor.java trunk/dna-common/src/main/java/org/jboss/dna/common/monitor/ProgressMonitorWrapper.java trunk/dna-common/src/main/java/org/jboss/dna/common/monitor/SimpleProgressMonitor.java trunk/dna-common/src/main/java/org/jboss/dna/common/monitor/SubProgressMonitor.java trunk/dna-common/src/test/java/org/jboss/dna/common/component/ComponentLibraryTest.java trunk/dna-common/src/test/java/org/jboss/dna/common/monitor/SimpleProgressMonitorTest.java Log: DNA-75: Added ability to add problems to a progress monitor. Also clarified some documentation and removed NullProgressMonitor (used only for testing) in lieu of using a mock object.
