Hello! I was testing the example from the guide: XML in Basalt, but it does not work straight from the guide.

If you do, in your xml <elem var="${table.value}"> the engine looks up the scope variable as scope["table.value"].

This means that the example:

<frame background="${colors.gray}">
    <label 
        x="2" y="2"
        text="${appTitle}"
    />
</frame>

local scope = {
    appTitle = "My App",
    colors = colors
}

Won't work, instead you have to write:

local scope = {
    appTitle = "My App",
-   colors = colors
+   ["colors.gray"] = colors.gray
}
