Hi,
I have a plugin which just is intended to provide an IAdapterFactory. So
I registered the factory. But when requesting the desired adapter always
null is returned. While debugging I found out that, on the one hand
side, the AdapterManager (in the getFactories method) correctly finds
the adapter type. But, on the other hand side, an AdapterFactoryProxy is
used. And the AdapterFactoryProxy checks if the plugin containing my
AdapterFactory is loaded. Unfortunately, my plugin is resolved and not
active and, thus, my AdapterFactory is not used und null is returned.
How can I achieve to get my AdapterFactory be loaded and used? Attached
you can find my manifest, my plugin.xml and my AdapterFactory.

cheers,
Jan

Hi,

To force the load of a class, you can use the "org.eclipse.ui.startup" extension point.
