The Joy of Flex

Great session today. You covered the topic very well and touch on the key parts.

Thank you, The session was very informative

Please say there will be a way to see a video of this. I’ve been struggleing to find info on this kinda stuff for ages and the slides allude to all the info i’ve been needing. Does anyone have access to a recording???

Someone at the Tuesday afternoon session asked about a problem they were having with pooling of remote data calls. It took me a while to find the reference, but here’s the info i gleaned from the Flex 1.5 documentation regarding simultaneous remote object calls;

Data service tag properties

If your application requires several RemoteObject calls to occur simultaneously, be aware that while the remote calls will be made in parallel, the results will not be returned to the Flex application until ALL the remote calls complete on the server.

This is because a single connection pool exists in the Flex gateway which executes the requests and returns when those requests complete.

You can circumvent this by modifying each tag. Add an endpoint attribute such that each URL is unique (see example). This causes the instance on the server to create a unique connection.

Example:

It has been found that while the Opera browser has no problem with this, IE seems limited to 4 concurrent requests. There may be a way to modify the registery entry for IE to increase this, but it has to be done by the end-user.

This was the solution to the problem we had with data pooling in our Flex 1.5 application. From the sounds of it, this same issue may still exist.

Thanks for the great talk…

oops, you’ll have to check the web page to see the example…

Yes a connect eSeminar on adobe would be great!!! I’ll keep an eye out

Just an addition to things that affect the efficiency of cacheAsBitmap
