Behavior Events not firing in library components

Posted on by jfrenc

I have a component library with a header component that has a button on it. The button OnSelect calls my coponent's OnClick method. In my app where I'm using the component, clicking on the button is not firing the OnClick method recently. This was working before (at least a week or two ago). I don't know if it's caused by a recent power apps release (maybe related to this issue: https://powerusers.microsoft.com/t5/Power-Apps-Experimental-Features/Latest-update-stops-Behavior-Events-accessing-component/m-p/2256007#M643 ?).

I can create a component in my Power App and the event fires for that one, but the component in my component library will not fire events (tested with two different components - both don't fire). It's also not showing the correct value of variables (they're always blank in the event expression window. I set ShowMenu to false in App.OnStart, but you can see here it looks like it is Blank:

Please share the library that you had the issue with when you can.

The app no longer references the component library. I could share the component library with you, but I don't see a way to export that from the Apps -> Component libraries page.

Is it possible for you to share your app and component library? I'd like to look at your setup and see if I can repro it myself.

@anhtruongMSFT , I'm on 3.23082.20, one version behind you. Hopefully I'll see it working again in the next version when I get updated automatically. Since I moved my components back into my app and it's working that way, I'm going to leave it as-is for now.

@jfrenc you can check and change your app/library version by going to Settings -> Support

Can you remind me how to check the version? I don't remember where to find that.

Re: Behavior Events not firing in library components

Hi @jfrenc , I have tried on my own with a component library and an app that have a similar set up as you have. I have a label that has Visible set to ShowMenu and my buttons are the same as yours. They are working as expected and both library and app are on 3.23083.16 version.

@ShantanuP , I'm assuming you're asking me for the expression, since it's my post (RameshMukka, I hope we get it solved for your sake, too).

Here is my definition of the event property:
Event property definition
Here is the OnSelect of the icon in the component.
Component's Button OnClick

Here is the app using the component and setting the OnMenuClick event. This fires now that I moved the component back into my app, but it stopped working when the component was in a component library (although it had worked for a couple of months previously):

@ShantanuP
I don't have the code now. But its about having multiple patch functions on one of the component Event type properties

Re: Behavior Events not firing in library components

Can you please share the expression on OnClick so that I can try to repro this on my end?
