    what i did was build a generic webservice that supports key and value pairs based on a type. So you can use the same service for multiple f4 helps. Which then has a db table in the backend where you fill in the values. You can also just do one service per combobox if you want to.

    So basically the service returns multiple entities with a key and a value. what you do then is to bind your control s items against that service.

    Something like this:

    <Select id="VehSearchStateInput" items="{ path: '/GenericKeyValueSet'

    }" width="100%">

    <core:Item id="VehSearchStateInputItems" key="{KeyV}" text="{Value}" />


    <l:GridData span="L9 M9 S12" />



    Then in your controller you can define a filter if need be that is called when the control is loaded:

    var oVehState = sap.ui.getCore().byId('VehSearchStateInput');

    var vState = "STATE";

    var oFilter1 = new sap.ui.model.Filter("Type", sap.ui.model.FilterOperator.EQ, vState);


    Then when you add the attribute change : with a function handler to your select control you can define a event that is executed when something is selected.

    You can get which item is currently selected via

    var vState = sap.ui.getCore().byId('VehSearchStateInput').getSelectedKey();

    which you then can put somewhere in your model.

    hope this helps a bit.
