[bug] .changed() not working

[d.healey]

Unless I'm doing something stupid, the .changed() function isn't doing its job.

This should print 0.5, right?

const var Knob1 = Content.getComponent("Knob1");

inline function onKnob1Control(component, value)
{
	Console.print(value);
};

Content.getComponent("Knob1").setControlCallback(onKnob1Control);

Knob1.setValue(0.5);
Knob1.changed();

@d-healey it works if you call it from another function (like a button)

[d.healey]

@iamlamprey Yeah I tested that too

Could this possibly be affecting my automation issue?

[d.healey]

@Dan-Korneff I don't think so because that works in HISE, but the problem here doesn't.

[Christoph Hart]

@d-healey The problem is that calling changed() in the onInit callback doesn't fire the callback. I took a look at the code and it explicitely cancels the execution:

https://github.com/christophhart/HISE/blob/d3f364f5c2832770a8bade634607e0f70b55f9df/hi_scripting/scripting/api/ScriptingApiContent.cpp#L944

I don't remember exactly why I did this (passive aggressive note to past me: a comment would have been helpful...), but I'm sure there are a few edge case problems that arise from this (eg. it will fire a bit later anyways because of the user preset load).

I've added a warning message that tells you that this function will not do anything, so now you're at least not left in the dark with that problem.

@Christoph-Hart Thank you for your response. What if I call the callback explicitly?

@Christoph-Hart Thank you for your response. What if I call the callback explicitly?

I just use a one-off timer...

[Christoph Hart]

@clevername27 if you mean calling the function directly then it will work (like any other function as long as its defined before the call), it‘s just the connection value change -> callback that is disabled during onInit.

@Christoph-Hart Thank you,
