"message:" binding with dynamic param in template

[sub <b4...@nwldx.com>]

Hi!

I'm trying to use a parameter with the message binding expression to get the
translation from my properties file:

messages.properties:

color.red=rot
color.blue=blau

template:

<t:loop source="colors" value="color">
    ${message:color.${color}}
</t:loop>

instead of "rot" I get "${message:color.red}" as the output.

What's the correct syntax to get this working? Or do I need a complete
different approach?

Cheers,
sub

There's no syntax for what you're trying to do.

As always, when there's logic, do it in Java, not in the template:

@Inject
private Messages messages;

public String getColorName() {
	return messages.get("color." + color);
}

<t:loop source="colors" value="color">
      ${colorName}
</t:loop>
