Trying to implement Intro and ran into strange behavior. If I include
(uncomment) the following code in my makeActions method in the
ActionBarAdvisor, then my application opens and immediately closes. The
action is an IWorkbenchAction. This occurs even though I have not yet put
it into the menu itself (I did originally, but am trying to narrow down the
problem).
// introAction = ActionFactory.INTRO.create(window); //
register(introAction);

Well, yes just a few hours ago ... ;-)
NPE is launched because Platform didn't have a product so
test the existence of it with a Platform.getProduct()
and create/register/ure the intro action only if the product is !=null
Once you will have a product configured, the intro will show up
=> use the launch configuration => launch product
Good luck,
Sincerely,
R.C

I have a product - in fact am building the application from the product
configuration. But I went to the product file again and launched from
there, and now it is working. I have changed no code, etc., so am
perplexed, except that now it works. Thanks.
