controlP5 - ControlBroadcaster Unknown Source error

rackatansky

I create cp5 objects in buildGUI() method which is called in constructor of VisualController class:

private void buildGUI() {

        cp5.addSlider("maxVelocity")
             .setPosition(20, 20)
             .setSize(guiDefaultWidth,guiDefaultHeight)
             .setValue(10)
             .setRange(0, 10)
             .setLabelVisible(true);
 // ... 
}

then in VisualController class I have methods that use the value from sliders :

public void maxVelocity(float theValue) {
        maxVelocity = theValue;
    }

then in main PApplet I have :

void maxVelocity(float theValue) {
        vic.maxVelocity(theValue);

    }

which calls VisualController respective method.

Code compiles and app is working but it reports below error:

controlP5.ControlBroadcaster printMethodError
