------------------------------------

             Summary: Unable to create empty or single valued String array property
                 Key: FELIX-4047
                 URL: https://issues.apache.org/jira/browse/FELIX-4047
             Project: Felix
          Issue Type: Bug
          Components: Maven SCR Plugin
    Affects Versions: maven-scr-plugin-1.12.0, maven-scr-plugin-1.8.0
            Reporter: Thomas Joseph


There is no way that I can declare an empty or a single valued String array is property.

@Property(label="Multivalued Property", value={"only-single-value"})
private static final String MV_PROPERTY= "multivalued.property";

OR

@Property(label="Multivalued Property", value={"only-single-value"}, unbounded=PropertyUnbounded.ARRAY)
private static final String MV_PROPERTY= "multivalued.property";

OR

@Property(label="Multivalued Property", value={"only-single-value"}, cardinality=N)
private static final String MV_PROPERTY= "multivalued.property";

All would generate the same DS XML file as:
<property name="multivalued.property" value="only-single-value"/>


As of now the only workaround is to declare an array with at-least two entries:

@Property(label="Multivalued Property", value={"only-single-value", ""})
private static final String MV_PROPERTY= "multivalued.property";

OR

@Property(label="Multivalued Property", value={"", ""})
private static final String MV_PROPERTY= "multivalued.property";
