I want to use the cron event to periodically syncronize the wave where
I put my robot with an external app. The need is to add a simple text
blip in the wave for each action registered from the external app.
I use Java.
I have two questions:
1. I have seen that my robot cron event starts regularly if the robot
is placed in a single wave (for example every 30 secs). But if I put
the robot in two or more waves I can see only one call and not one
call for each wave.. Is it correct?
2. To use cron and update my waves I found and use this code:
....
if (bundle.getEvents().size() == 0) {
LOG.warning("Cron event now");
....
and it's works (i can see the log in appengine) but when I try to get
the wavelet and append my message:
Wavelet wavelet = bundle.getWavelet();
Blip blip = wavelet.appendBlip();
TextView textnew = blip.getDocument();
textnew.append("30 secs message...");
the function getWavelet() value is NULL.
How can I get wavelet data from wave who contains the robot instance?
Thank you
