WebDynpro Does Not Recognize the Data Type

Question

I've had this problem happen to me before, but I can't remember how to resolve it. Basically, there is an SAP tutorial on the GeoMap that says to create a contect attribute with a type of com.sap.ide.webdynpro.uielementdefinitions.GeoObject
When I go to the properties on the context attribute, and click "..." I select "Java Native Type". Then I enter in the type above, and I get an error saying, "Type not found in the scope of the current project".
Do I have to do something prior to assigning the type so that it recognizes the GeoObject. If I search the Java Native Types, there are other GeoObject, but they are not the right ones.
Any help in this one would be appreciated.
Regards,
Tom

Answer 1

This is a Java DDIC type. You may assign it to the context attribute by selecting "Dictionary simple type", choose package com.sap.ide.webdynpro.uielementdefinitions" and here you find type "GeoObject".
For reasons of backward compatibility, the DDIC types for the UI element libraries Core, Standard and BusinessGraphics are all located in this package. For every other UI element library, the package is "com.sap.ide.webdynpro.uielementlibraries.<libraryName>".
General rule: Context attributes to which UI element properties are bound must have DDIC type, not Java native type.
