Extend the Context of the GeoServiceView 

The context already contains the context attributes for the start and destination addresses. You now want to add the context attributes and context nodes essential for GeoService applications to the GeoServiceView context.

Procedure

In the View Designer, switch to the Context tab and extend the existing context structure as shown in the figure below:

Make the following settings for the properties of each context element:

Context Element	Type	Properties	Value
DestinationAddress	Value node
geoPos	Value attribute	type	com.sap.tc.webdynpro.clientserver.uielib. graphics.api.WDGeoPosition
GeoData	Value node	cardinality	0..n
geoObject	Value attribute	type	com.sap.ide.webdynpro. uielementdefinitions.GeoObject
RouteInformation	Value node	cardinality	1..1
Distance	Value attribute	type	double
Duration	Value attribute	type	time
StartAddress	Value node
geoPos	Value attribute	type	com.sap.tc.webdynpro.clientserver.uielib.graphics.api.WDGeoPosition
mapBorder	Value attribute	type	com.sap.tc.webdynpro.clientserver.uielib.graphics.api.WDGeoBorder

 

Assign a Java Native Type as the Data Type to a Value Attribute

The values of the value attributes geoPos and mapBorder require a Java Native type as the data type. Proceed as follows:

...

       1.      To open the dialog box for selecting the Java Native Type data type, choose  (in the value column for the property type).

       2.      Select the radio button Java Native Type and choose Browse… Another window appears.

       3.      In the input field for value attribute geoPos enter WDGeoPosition (or, as value for value attribute mapBorder enter WDGeoBorder, respectively). You can now select the WDGeoPosition in the bottom list. Choose OK to confirm.

       4.      Choose Finish to confirm. 

       5.       

Assign a Simple Type as the Data Type to a Value Attribute

The value of the value attribute geoObject requires a Simple Type as the data type. Proceed as follows:

...

       1.      Use   (in the value column for the property type) to open the dialog box for selecting the data type Simple Type.

       2.      Select the DDIC Simple Type radio button and open the node DtDictionary – com.sap.ide.webdynpro.uielementdefinitions. It contains all data types that refer to specific UI element properties.

       3.      Select the data type GeoObject and choose Finish to exit the dialog box.

Result

You extended the context of the Web Dynpro application ”Using Geo Services”.
