Hello All,
Has any one had any luck using the special command
"PERFORM-ACTION-SEND-EVENT F" to send events to their own custom Java
module?
>From an active link on a button I action the following "Run Process"
command.
PERFORM-ACTION-SEND-EVENT F536870916 MYTESTEVENT "$message$"
Checking the logs on my Java Module, Mid Tier DV and Tomcat I fail to
see any thing happen when this command is run and think it could be a
configuration issue on the server? Also I have had success when sending
events back to the parent form from the JavaScript calls created by the
Java module.
The Data Visual Module/Definition Registration is similar to that of the
BMC's CIViewer. I'm running 7.0.1 patch 2, The midtier is running on
IIS->Tomcat
My source code below is a modified version of HelloWorldPlugin from the
Arswiki web site. I've added some logging and javascripts to send events
to
The mid tier and parent form.
Thanks,
Graham
