-------------------------------------
Summary: Metatype AD empty String default value
Key: FELIX-6009
URL: https://issues.apache.org/jira/browse/FELIX-6009
Project: Felix
Issue Type: Bug
Components: Metatype Service
Affects Versions: metatype-1.2.2
Reporter: Andreas Lemmer
I have an AD with a default value which is an empty string, like
{{<AD id="server" type="String" default=""/>}}
According to the OSGi Spec, the method AttributeDefinition.defaultValue() in
this case must return an array with one element (which should be the empty
string), because the cardinality is 0 (implicit) and the default is defined.
However, the Felix Metatype Service implementation returns null for
defaultValue().
In my use case, this breaks everything, because a null value indicates a
configuration error (default not given, although mandatory) whereas an empty
string is perfectly fine.
