Does anybody have an idea what I am doing wrong?
Using the latest snapshot of tapestry5.
In the following code :
@Inject
private ComponentResources resources;
/**
* Act upon the "link"
*/
void onSelected()
{
Link link = resources.createActionLink( "action", false,
contextArray );
}
I get a NPE with the following stack trace
