Classes inaccessible from events

Hello,

I’m having an issue were I can’t seem to access custom classes / types from certain events. One that I’m able to consistantly replace is a simple -OnClick. Below is an example using a static member, but this is an issue with instance members as well.

New-UDGrid -Container -Content {
    New-UDButton -id 'btn_TestButton' -Text "$([Example]::staticString)" -OnClick {
        Show-UDToast -Message "$([Example]::staticString)"
    }
}

class Example{
    static [string] $staticString = "I'm a button!"
}

The result is that I see a button with the text “I’m a button!” on the screen, meaning that it can correctly refrence the class, but when it’s clicked I get the following error:

Unable to find type [Example]

However, if I make a function that references the class, it DOES work. This sets the text of the button to “I’m a button!” and displays that same piece of text on the -OnClick event.

New-UDGrid -Container -Content {
    New-UDButton -id 'btn_TestButton' -Text "$([Example]::staticString)" -OnClick {
        Show-UDToast -Message "$(Get-ExampleStaticString)"
    }
}

function Get-ExampleStaticString {
    return "$([Example]::staticString)"
}

class Example{
    static [string] $staticString = "I'm a button!"
}

Anyone have any thoughts or workarounds besides calling object members from a separate function? This works okay for this example, but with instance members, the object has to be stored in a global variable and it doesn’t really make any sense to have to use a separate function to manipulate the object.
