------------------------------------
@ClausIbsen Thanks for your reply
I poked around and found that it was populating the map with
ExchangeHelper.createVariableMap, which called populateVariableMap
{code}
public static void populateVariableMap(Exchange exchange, Map<String, Object>
map) {
map.put("exchange", exchange);
Message in = exchange.getIn();
map.put("in", in);
map.put("request", in);
map.put("headers", in.getHeaders());
map.put("body", in.getBody());
if (isOutCapable(exchange)) {
// if we are out capable then set out and response as well
// however only grab OUT if it exists, otherwise reuse IN
// this prevents side effects to alter the Exchange if we force
creating an OUT message
Message msg = exchange.hasOut() ? exchange.getOut() :
exchange.getIn();
map.put("out", msg);
map.put("response", msg);
}
map.put("camelContext", exchange.getContext());
}
{code}
I was trying to find out where the placeholder's properties were defined as I
couldn't find it in the exchange object, for some reason
exchange.getContext().getProperties() doesn't actually contain this information
(I wonder what properties are returned from getProperties? It was an empty map
when I checked)...
Could you suggest where this information may be stored? I'm offering to make a
patch for this, but I may need a small bit of help finding out where the
property placeholder information could be accessed from :)
