Working with fzZzy on #divmod, I made the following change to my local twisted/web/woven/flashconduit.py to make LivePage work for me. I'm using guard sessions (which appear to not be supported by the current code) so in my case the sessions are stored on the SessionWrapper. I really don't know squat about the way the code should be, so hopefully someone else can take a look at this and apply a real patch. I'd gladly do the real thing, but it would take me a *lot* longer to do. :-) Thanks. -Justin --- flashconduit.py.orig 2003-11-17 13:18:37.000000000 -0600 +++ flashconduit.py 2003-11-17 13:18:43.000000000 -0600 @@ -16,7 +16,8 @@ #self.lp.unhookOutputConduit() def lineReceived(self, line): - session = self.factory.site.getSession(line) + #session = self.factory.site.getSession(line) + session = self.factory.site.resource.sessions[line] self.lp = lp = session.getComponent(interfaces.IWovenLivePage) lp.hookupOutputConduit(self) ----- Original message ----- From: "Justin Johnson" <justinjohnson@fastmail.fm> To: "Twisted-Python" <twisted-python@twistedmatrix.com> Date: Thu, 13 Nov 2003 11:19:09 -0600 Subject: Re: [Twisted-Python] LivePage CACHING Problem I found the following post that looks similar to my problem. http://twistedmatrix.com/pipermail/twisted-python/2003-May/004170.html But since I have my own tap, I copied the code from web/tap.py into my code to start up the FlashConduitFactory.

Hi,

I am currently trying to use LivePage to update the cells of an html table with results from processes initiated in various PB services. The client intiates requests in the services and those services call back into the client's (a pb.Referenceable) remote_updateStatus method to update the table which displays the results. I have test code that simulates this and everything works fine. Javascript is sent to the browser to update the cells of the table. Works really slick. However, now that I tried to hook it up to PB, the LivePage javascript sending part isn't working. When I make the page.sendScript(script) call I get the following in the log.

2003/11/13 10:25 CST [Broker,client] Sending javascript to page <twisted.web.woven.utils.WovenLivePage instance at 0x4089944c> 2003/11/13 10:25 CST [Broker,client] CACHING [<twisted.web.woven.utils.Script instance at 0x4089906c>]

All future sendScript calls append the script to the cache. Everything else is working appropriately, and all code is executing as I'd expect, except that the javascript doesn't send properly. Is there something in particular I should be looking for here? I don't see what I'm doing different, but since LivePage is quite magical to me I'm not sure where to look.

On a slightly different note, is there LivePage-ish support in nevow, and do you recommend moving to that yet?

Thanks. -Justin
