Use of oData Navigation in UI5

Hello everybody,

I'm playing around with the Gateway and oData and found the navigation property very interesting.

I've created a OData service (ZSERVICE) with two Service Implementaions ZMASTER and ZSLAVE, and I Created a Navigation MASTERtoSLAVE.

The cardinality is ZMASTER 1 - n ZSLAVE.

Now I want the data displayed in a UI5 Page.

I created two Tables, set the Model of the View to /ZSERVICE and the bound the two Tables to /ZMASTERSet and /ZSLAVESet.

Now every table gets their information. What i want to achive is: Loading of Master Table - > click on Master Table -> Call of OData Service Slave Table with Key and display of Data in Slave table.

Any ideas how to get this to work? Or am I on the wrong path?

Thank you for you input.
