I am using the following method in my robot to process the list
of JsonRpcResponse objects
returned from a call to com.google.wave.api.AbstractRobot.submit:
private String getParam(List<JsonRpcResponse> response, ParamsProperty p) {
for(JsonRpcResponse jsonRpcResponse : response) {
Map<ParamsProperty, Object> data = jsonRpcResponse.getData();
String param = (String) data.get(p);
if(param != null)
return param;
}
return null;
}
(from:
http://www.mail-archive.com/[email protected]/msg04969.html)
This is very useful since I can do something like:
String newwaveid = getParam(submit(newwave,
rpcserverurl), ParamsProperty.WAVE_ID);
to get back the id of the newly created wave from the WIAB server.
This was working fine until a few days ago when I started getting
a NullPointerException
from the line:
Map<ParamsProperty, Object> data = jsonRpcResponse.getData();
It seems that the submit call is now returning an empty
list of JsonRpcResponse objects.
Has anything changing in the last couple of days that could have caused
this?
Any help would be greatly appreciated. I have to give a demo of my robot
tomorrow
so I am in desperate need of some assistance.
Thank you,
Patrick Jennings
