AudioProcessorParameter implementation causes Assertion failure in juce_AU_Wrapper.mm:538 on debugging

Hi! This is my first post so hello world. 

As soon as I tried to implement AudioProcessorParameter I got Assertion failure in juce_AU_Wrapper.mm:538 on debugging with Logic. I tried to debug JuceDemoPlugin with the same results. Any ideas how to fix?

 

Thanks, Karolos

Nevermind, it seems an instance of my plugin that was causing the assertion failure, and its is connected to the min-max value of a parameter that must be 0.0-1.0 range.
