[ http://issues.apache.org/jira/browse/FELIX-109?page=all ]
Felix Meschberger updated FELIX-109:
------------------------------------
Attachment: ComponentMetadata_fm_20060830.diff
The problem is that the ComponentMetadata.addProperty method feeds an internal
Properties instance with the registered property name and value while the
ComponentMetadata.validate() assuems the keys to be PropertyMetadata instances.
I propse the attached fix, which is implemented as follows:
addProperty: feeds a list with the PropertyMetadata instances
validate: iterates the PropertyMetadata list, validates each entry and
fills a Hashtable
with the validated property name and value
getProperties: now returns a Dictionary (which is the Hashtable filled by
validate)
The choice of using a Hashtable instead of a Properties instance is, that the
service property values need not be String objects, while the Properties object
assumes String values.
