> Key: FELIX-5038
> URL: https://issues.apache.org/jira/browse/FELIX-5038
> Project: Felix
> Issue Type: Bug
> Components: File Install
> Reporter: Gregor Zurowski
> Priority: Minor
>
> In a Karaf/Blueprint setup, I noticed an issue related to Config Admin and
> Felix File Install where configuration properties are not synchronized with
> the corresponding configuration file once Metatype information is added to
> the bundle.
> In a simple test bundle, the configuration properties are implemented using
> property placeholders in Blueprint as follows:
> {code:title=blueprint/blueprint.xml}
> [...]
> <cm:property-placeholder id="config-test-blueprint-placeholder"
> persistent-id="test.config" update-strategy="reload">
> <cm:default-properties>
> <cm:property name="test.property.1" value="Test 1" />
> </cm:default-properties>
> </cm:property-placeholder>
> [...]
> {code}
> The corresponding configuration file in $KARAF_HOME/etc looks as follows:
> {code:title=etc/test.config.cfg}
> [...]
> test.property.1 = Test Value 1
> [...]
> {code}
> When adding the following Metatype information, the synchronization mechanism
> stops working, i.e. changes made in OSGi config admin using webconsole are
> not written back to the configuration file:
> {code:title=metatype/metatype.xml}
> [...]
> <AD name="Test Property 1" id="test.property.1" required="true"
> type="String" default="Default value 1" description="This is test
> property 1" />
> [...]
> {code}
> The only way to fix synchronization is to add the following attribute
> definition to Metatype:
> {code:title=metatype/metatype.xml}
> [...]
> <AD name="felix.fileinstall.filename" id="felix.fileinstall.filename"
> required="true" type="String" default="" description="Don't
> modify this property!" />
> [...]
> {code}
> This has been also discussed on the Karaf users mailing list, see:
> http://karaf.922171.n3.nabble.com/Blueprint-Property-Placeholders-with-Metatype-Information-td4042619.html
