Hi Kevin,
the component you're looking for is OutputRaw:
http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/corelib/components/OutputRaw.html
If you prefer to code your own component with MarkupWriter you'd do it like
that:
public class PlainOutput {
@Parameter
private String text;
void beginRender(MarkupWriter writer) {
// any string operation may be here, null-checks etc.
writer.writeRaw(text);
}
void afterRender(MarkupWriter writer) {
writer.write("Cheers");
writer.writeRaw("<br />");
writer.write("Christian");
}
}
