Metatype configuration supported data types - tables/lists? [message #1592110] Thu, 29 January 2015 23:09 Go to next message

I was wondering if OSGI-INF/metatype/xxx.xml configuration file supports more complex types like lists with multiple columns or editable tables.

I am looking for something similar with the elements found on the kura Admin pages (Firewall or Packages) as I would like for example to be able to edit in a config interface the setting for all 60+ GPIO pins on BBB and avoid a very large xml file with simple fields like strings and boolean values.

Thanks for any guidance.

Hi Dan,

The metatype configuration files adhere to the OSGi Compendium spec (v4.3) [1] for the Metatype Service. If you haven't, it is properly worth reading the sections on Configuration Admin and Metatype Service. The spec states that the Metatype Service is only intended for simple data types. As you may have noticed, Kura displays these attribute definitions as:

if options are present => display drop down list
if type is boolean => display true/false radio buttons
else => display input box

The tabs you described are not using the Metatype Service or Configuration Admin. They are using internal data models to track changes made through the web UI. For dealing with a large set of inputs, I would recommend using a configuration file or for GPIO have a look at the device I/O features [2] we recently added. Otherwise, I think you would need to extend the UI and create your own custom tab.

Let me know if I can clarify anything further.

Hello, David

I am wondering if you have any suggestions on how to extend the Web UI and create self-defined tabs. I really like the way that in Cloud Service, we can just click Cloud Service, Data Service and MqttDataTransport to switch to different configuration page. I wish I can do that for my application as well.

Thanks
Phoebe

I'm also willing to learn as Phoebe, if those utilities are possible.
