XTemplate with TextResource as source

[micgala]

Hi.

Does anyone know how can I create an XTemplate with a TextResource as a source?

I've tried this, but it fails by telling me that the value must be an expression.

private static final String TEMPLATE_STRING = NotificationResources.INSTANCE.templateBar().getText();

public interface SlotTemplates extends XTemplates {
@XTemplate(TEMPLATE_STRING)
SafeHtml hello(TemplateBean data);
}
