How to get indicator from HandleUIMessage vi to Top Level.vi

[Skoda3]

I want to custumize Simple user interface for testand (Labview). 

I read all of this:

https://www.ni.com/en/support/documentation/supplemental/14/working-with-the-teststand-simple-user-i...

At the : "Handling additional events" there shows how to create callback vi so that we can do some event handling code when UI message comes:

 But If I put some boolean indicator here inside and connect it to connector pane to be used for example to indicate some event is done, i get broken Wire:

Why this is happening and how to get this indicator to the top level vi?

I have some presentations for this in our TestStand user group.  Hope these help:

The key is that you need to pass a reference to your FP object into the callback VI.  The User Parameter has to match so you don't have a broken callback wire.

Hope this helps,

The presentation is ok, but I have some additional questions since I cannot realize it...

I will use TS Simple UI. 

1. First I create Chart indicator on the top level VI front panel like this and create reference of this chart:

2. Second I drag and drop Chart reference created in step 1 into UI Type Def. inside of visible controls section (see red arrow):

3. Then I connect Waveform chart reference into initialization cluster:

4. When I create UserMessage Event Callback, I get broken wire, it says thath TestStand UI Data cluster contains an error:

What I'm doing wrong here?

It looks like you just need to reconnect the control to the type def.  In fact I would make it a strict type def if it were me.

One way to reconnect it is just replace it.
