When launching one of my addons I display a progress dialog. This works fine when executing from XBMC but when launching from a json-rpc call, XBMC hangs with no further information.

PHP Code:

However if I add a notification or as in this case run

PHP Code:
xbmc.executebuiltin('Dialog.Close(all, true)') 

Everything works just fine (continuing from the log above)

I suspect there is some issue with XBMC's "opening stream" dialog showing at the same time. A race condition?
Anyone else experienced this?

Hi,

Code:
21:19:17 T:5764   DEBUG: JSONRPC: Missing property "playlistid" in type

"playlistid" is required. 0 for audio and 1 for video. Try:

Code:
{"jsonrpc": "2.0", "method": "Player.Open", "params":{"item": {"playlistid": 1, "file" : "plugin://plugin.program.x/?x" }}, "id" : "1"}

Let me know if it works because I'd like to interact with addons via JSONRPC as well Smile

I have actually experienced this, but starting from with in XBMC. Though it does not always happen, but often.. I thought I was going crazy.. Smile

Your syntax doesnt work for me. By forcing the dialog to close this works just fine.

Any solution? Should I post a track ticket?

A trac ticket would be a good start.. If you are on Linux(or OSX I think) try to provide a backtrace of the XBMC when the hang up happens. I've been chasing this around(and other hangs regarding XBMC and addons) but everytime I'm in the hunt, I can never get them to come up.

Sorry, running win7 so it will take some time to get linux up and running. I think it has something with the doModal()...

I managed to capture a BackTrace when this happened for me, so I submitted a Trac Ticket for this. Feel free to add to it..
