[AG-DEV] AG3 Shared App Migration

[Susanne Lefvert]

Hello Todd,

This document describes the issues in more detail.  I would recommend  
reading it while looking at the shared presentation code that we  
already converted.

Just trying to migrate my SharedDesktop shared app to AG3 and seem to  
be running into a couple of
the issues listed here:

http://www-unix.mcs.anl.gov/fl/research/accessgrid/wiki/moin.cgi/ 
SharedApplicationMigrationIssues


Can someone expand on some of these issues?  Specifically:


* Connection id needed for venue data store - should be retreived  
via .app file.


	I think you are just referring to the venue data store - not the  
shared app datastore - correct?




* Reactor imports and wxCallAfter interleave call needed for events  
to function.
	Figured out this one I think.  Added:
		try:
		        from twisted.internet import threadedselectreactor
		        threadedselectreactor.install()
		except:
		        pass
		from twisted.internet import reactor

	plus the reactor.interleave(wxCallAfter) call in the panel code




* More restrictive rules on data format for events - do not send  
tuples and dictionaries.
	Running into this issue right now :-(  Was sending a tuple - what  
are my choices now??


* Data received from the application service (sharedAppClient.GetData 
()) may be unicode - convert
data to correct type.

	Haven't got the data yet - so can't know if I'll run into this  
issue.  Can someone expand?



* Get public id of sender by using the new event method; GetSenderId()
	Expand?



Thanks!

Todd
