| A Recent Source of the "Could not create action delegate" Error [message #190811] |

When I upgraded to a recent Eclipse integration build, my plugin stopped
working. When I tried to invoke a plugin-supplied action, I got "The chosen
operation is not currently available" at the user interface and "Could not
create action delegate for..." and "...unable to load class..." in the error
log.
After poking around for quite awhile, I found the problem. My plugin
declared the contructor MyPlugin(IPluginDescriptor), but the latest builds
require an argumentless constructor, MyPlugin(), as well. Eclipse couldn't
load my action delegate class because it couldn't instantiate my plugin
class.
I hope this explanation helps someone else with the same problem. /Jim White

the problem disappeared when I recreated a project without OSGi support
