The AdaptExpression#evaluate method only checks if there is an adapter provided by the AdapterFactory. An object implementing the IAdaptable-Interface may return additional adapters not available through the AdapterManager.

Examples are the FileStoreEditorInput or WorkbenchPart-Subclasses.

This was a major problem when implementing our Common Navigator Framework ContentProvider, where contribution didn't appear. 

Workaround: 
Never define an Adapter inside an IAdaptable, always delegate to the Platform AdapterManager as implemented in PlatformObject and register a AdapterFactory via ExtensionPoint.


 

Reproducible: Always

Steps to Reproduce:
1. Create a Class implementing IAdaptable and returning an adapter
2. Invoke a AdaptExpression tesing for the adapter on a selection containing the adaptable
