are you using the ProtocolBrowser class that comes default with Pharo 5? (In the Spec-Examples package). This is different from what is in the booklet, the code in Pharo 5 is not up to date. For now, you should define a new protocol browser class (MyProtocolBrowser for example) and the other classes that are in that section. Sorry for that...

Does this mail seem too brief? Sorry for that, I don��t mean to be rude! Please see http://emailcharter.org .

Subject: SpecBooklet: Strange behavior of ProtocolBrowser

Hi,
I'm playing with the ProtocolBrowser class, as coded in the
"SpecBooklet.pdf" document (release of the 3rd August 2016).
I'm using Pharo 5.

I'm experiencing a strange behavior of the ProtocolBrowser instance:
-if I open a ProtocolBrowser instance, and I click on a "api" item, I
do not get any code in the text pane.
-If I open another ProtocolBrowser instance then I do not see any code,
even in the "api" protocol than the "api-events" one.
-If I open a further instance then the widget works correctly, showing
the "api" or "api-events" code in the text pane.

Please note that the ProtocolBrowser is instantiated as follow:
(ProtocolBrowser new) openWithSpec

Could my Pharo image be faulty?
Is there some problem with ProtocolBrowser>>initializePresenter?

Thanks,
Matteo Bellotto
