We have a Flex application which doesn't currently use the Flex framework as an RSL. We're considering switching, but we're not sure what proportion of users will already have the framework cached.There's an added complication in that we're using the data visualisation components too, and we may have a choice as to which version of the framework we use.
View 2 RepliesHow do you know if the browser is actually using the cached swf RSL/library for Flex projects? I would like to be able to do different things from the preloader based on whether or not the user has never downloaded the library vs. they have it already cached by their browser.
View 1 RepliesIn my application, I make numerous calls to preload images to brower cache in the background using Loader instances and ignore the complete event. I don't store the results in the application, but rather want to store them in the browser cache. The images have long Expires header dates.
When I want to use a particular image(s), I again use a Loader instance and call the same url and listen for the complete event to load the file to an Image.
The problem is that when I re-request the url for the "cached" image, it is making an http request with response 200 status, which I presume means it is hitting the server. How do I make sure that a request for a cached image never hits the server from Flex? I am finding that any request to a url for a cached image (with a long expires header) is making another request to the server, or at least that is my interpretation of it in Firebug.
I have a project that is for several customers, the only difference is in the DB, everything else looks the same, except for the main page's text. That is loaded from an external swf file. I created a library, compiled it as an swc, imported it and using it as an RSL. The problem is that if once I've opened the page, and afterwards update the rsl (because changes in the text are needed), than it's already cached by the browser (not the flashplayer's cache but we shouldn't discuss this please!) and the updated swf won't be loaded. If I use it as an external, the page won't even start up (the browser says it's loaded, but it's blank, not even the loading progess bar of flex appear)
<local:MainPage includeIn="default" currentState="{MainPageState}" id="Page"
width="100%" height="100%" />
this is the code on the main page, if I comment this out, than the whole thing loads, even with the use of the "external" link-type. in the design view, I see the component, but I get a warning for the library:
Design mode could not load MainPage.swc. It may be incompatible with this SDK, or invalid.DesignAssetLoader.CompleteTimeout)
I'm currently working on a project that needs to request a url multiple times. Having studied the the HTTP Proxy (Charles) it seems that AIR will cache the first response and then return the same response for each subsequent request.Does anybody know how to know if the response has been cached other than setting the URLRequest to useCache, but this doesn't say if the response was a cached response or not. The digest isn't set on the URLRequest either, although it does mention this is for swz only, so how does it know if the content is the current content or not? Is the responseHeaders used to find out how long to hold the cache i.e.Cache-Control: max-age=900
Also does anyone know how to flush/purge the cache or are we at the whim of the GC and in that case how does it know if to leave it in the cache or now?This makes sense to me, but still I would like to know how to regulate this cache.Further more: I've tested a set up where parallel URLLoaders (10) are made and created which open the same url to see what happens in that instance. It seems that each parallel request is made until a successful response is given, all subsequent calls are then cached. Calls which are sent out before the successful request is then completed. It looks like the items which are already in being processed do not use the cache and return with correct data.Additional The AIR runtime doesn't even send a "If-Modified-Since" header, so the cache isn't even honoring HTTP protocol. So it seems as if Adobe has implemented it's own version of a cache which doesn't even use HTTP/1.1 Header Field Definitions.

View 14 RepliesI need to get the propotion on a text and NOT the textfield that the text is in. I've have trying to use a bitmap and then get the highest and lowest pixel (Y) on the text and also the moast left and right pixel (X) and then take the difference in X/difference Y and then get my propotion. Unfortunately i won't get the same propotion as if I'm looking och a text written in eg word.
Dose anyone now why? Can I found the propotion in any other way?

View 1 RepliesI have a rather large Flex SWF and am breaking it up into separate Modules. There is some overlap between the modules and I want to put all of this into one shared RSL. The problem is that this RSL gets really large as soon as I use any Flex code because it has to include the Flex Library.Flex Builder doesn't seem to give me the option to use the Flex framework RSL in a library. Also compiling with compc and passing the runtime-shared-library-path doesn't seem to actually use the rsl.So it seems like this is something that is unsupported? Does anyone have any idea how I can do this? Is it just not possible? Is this something that is likely to be supported in the future or already supported in Gumbo?

I was reading these days about large projects implementation in python and Flex, and very often people praise the use of framework (like Cairngorm, PureMVC or others) over traditional OOP coding.
I think i dont really understand the advantage of using FW, which is the strong point over classic programming? how big should be the project in order to use FW? it is intended mainly for web-applications? or can be used for desktop apps as well?

View 1 RepliesWe're working to build the front-end of our application and struggling with selecting a good UI framework since we're not experienced UI people (we're mainly back-end developers). The central issue is that we don't know what we don't know and don't know how to best weigh our different options.At the moment, we're evaluating Flex, ExtJS, and Vaadin. Is there another option we should consider? What, are the major elements we should evalutate on?

I'm attempting to create a Flex Project that will cause the Flash Player to cache the Flex framework. Flex Builder comes with Flex SDK 3.2.0.3958 and setting the Framework Linkage to use Runtime shared Library (RSL) under Project Properties -> Flex Build Path will separate the framework from my main application and I see that my project's bin-debug directory contains framework_3.2.0.3958.swf and *.swz for distribution.Flex SDK 3.4 fixes a few bugs, so I configured it as another available sdk and set it as the default SDK. When I compile, I expect the bin-debug directory to contain framework_3.4.0.9271.swf and *.swz; however, Flex Builder is still writing framework_3.2.0.3958.swf and *.swz.

From what I understand a framework reduces complexity in areas that are common, like a log-in system. I use ASP.NET MVC at work and have done some work in Zend Framework but do not get how a framework helps with client side development. The reason ASP.NET MVC is used at work is for Unit Testing - does a Flex framework help with this too? why I should or should not use a framework with Flex?
