Hi Sven, how are you doing? Firstly let me ask you how should I load Zinc. Iâm doing it like this: Gofer it url: 'http://mc.stfx.eu/ZincHTTPComponents'; package: 'ConfigurationOfZincHTTPComponents'; load. (Smalltalk at:#ConfigurationOfZincHTTPComponents) project latestVersion load: 'WebSocket'. (Smalltalk at:#ConfigurationOfZincHTTPComponents) project latestVersion load: 'SSO'. Gofer it url: 'http://mc.stfx.eu/Zodiac'; package: 'Zodiac-Core'; package: 'Zodiac-Tests'; load. Is that the right source/way? Secondly, Iâm experiencing this in the latest version: Whatâs the package that has the missin ZnWebSocketControlFrameHandledEvent? thanks! sebastian o/ blog: http://sebastianconcept.com LinkedIn: http://www.linkedin.com/in/sebastiansastre github: https://github.com/sebastianconcept
