[flexcoders] Trapping on BlazeDS server a lost connection to a Flex client. How?
Hi all, I think it has been asked before but I don't recall any answer as this is: 1. Not a Flex directly related issue, 2. Not even a BlazeDS issue per se, My client-server application depends on a Flex client and a Tomcat + BlazeDS + MySQL + Hibernate backend server. It tracks whether a user is logged in by keeping a InSession boolean field in the database. This InSession starts the session clock by the time the user has properly logged in and stops by the time he has properly logged out by Exit the app. Then the database is updated and that user is marked as InSession=false, while that session has been timed. But if the communication channel goes down (Internet, LAN, etc), or the client's browser is inadvertently force closed, the database loses track/sync of the user and keeps reporting as InSession=true, while session time keeps running indefinately. What I need is a server side procedure that: 1. Either catch an exception on losing connection event, or 2. in a continuous loop scans for connected users (out of a list of InSession=true) Obviously losing the client-server connection is a very generalized problem to track and needs more specific solutions. I am not sure if this can be solved in BlazeDS level, or I have to go to WEB server sockets. But may I ask if anyone has a suggestion, or some relevant documentation for me to study? Thanks all George
Re: [flexcoders] Trapping on BlazeDS server a lost connection to a Flex client. How?
If you are using sessions you can add a session destroy filter in tomcat that retrieves the user id from the session and updates the db that the user has logged out - that will work - the only problem is that if you use a long session timeout your db field will be updated at the end of this period...

You will either have to disable the datagrids click event handler on that
specific column or figure out a way to put each link in its own column.

I'd add to that: if you're going to go with this method, you're probably going
to want to pass in a function or two that will give you back the strings you
want to use. You'll attach these to the ClassFactory like so:
cf:ClassFactory = new ClassFactory(com.yourDomain.view.CustomRenderer);
cf.properties = {string1Function:someFunction;
string2Function:someOtherFunction};
Another way you can handle this is to use the DataGrid_withStyle at
flexdiary.blogspot.com, then have your styleFunction pass back an object with
properties that you'll then use to populate your strings in commitProperties
(see the example itemRenderer for how you can handle grabbing the style
information and use it).

[flexcoders] Adobe pulls Single CPU and 100-user licenses
I'm curious how many of your projects were deployed into production using the no-charge Single CPU (or the 100-user departmental) licenses of LCDS 2.x. Since the release of LCDS 3.0, neither of these licenses exist. This leaves our small business customers running in production using the Single CPU license with no upgrade path going forward, unless they can come up with the steep license fees for ES2. I doubt any of our customers will be able to afford it. Needless to say, this seriously impedes our ability to do business on the LCDS platform going forward in the SMB market we serve. It also leaves our hands tied with respect to the software we've already developed and deployed. BlazeDS is not an option - it would require a total rewrite of client and server, and mass annihilation of features. How are these changes affecting your business?

below, and some timee there are some of the columns need to hide and show
too.How can i do this?
var xLabels:Array = (Xs[0].label as Array);
labels = new ArrayCollection(xLabels);
var hObj:Object=new Object();
for (var lObj:int=0; lObj labels.length; lObj++)
{
hlabel =labels[lObj];
}
public var arrRawData:ArrayCollection = new ArrayCollection();
__model.arrNewData = event.result.rawdata.record as ArrayCollection;
var xmlResult:XML = XML(event.result);
Any help would be greatly appreciated.

[flexcoders] Re: Should I follow this recommendation when it comes to Flex learning curve?
Why can't you learn both at the same time? Flex by itself is all nice and dandy but the power comes from being able to create cross-browser, desk top deployable front-end to business processes and data. Techincally, the business logic can be built into Flex for a lot of stuff, but it's actually better to do that elsewhere like a middleware between the data and front end. Anywho... having skills to handle both modeling data on the server, processing it via the business logic layer, and then serving it up/to the flex front end is some strong Kung Fu. --- In flexcoders@yahoogroups.com, fred44455 fred44...@... wrote: I already know some html and CSS .

It might be a good opportunity to loosely couple things and apply a more Service Oriented Architecture approach.

[flexcoders] Resize and Save an Image
Hey does anyone know if it's possible to resize and image in flex and save it to a mysql database so that I have say a 512x512 and a 60x60? If so, is there a tutorial out on the web somewhere? This is just to avoid having to resize it myself manually when I receive the 512x512.
[flexcoders] Drawing a Grid
Does anyway happen to know the best way to draw a grid inside of Sprite that uses the least amount of mem/processing? I have a sprite that can be up to 40,000 pixels wides by 40,000 pixels high and I need to draw a grid in the background of the sprite, similar to Visio. The issue is when I just try drawing the lines in the sprite it takes up a huge amount of memory. I was wondering if maybe I only draw the lines 2x the width and height of the screen and then if the user scrolls the swf then redraw the lines based on position? Anyone ever tried this or have any suggestions or examples?
[flexcoders] Troublesome problem with debugger - local variables not showing
I ran into an extremely strange problem today with the debugger. Placing a breakpoint in a certain function was NOT showing my local scope variables in the list. At all. The only thing I have showing is this and, if the function has any inputs, _arg1, _arg2 etc. Some variables I can place a watch on and I can see, but others in the same function show that they do not exist. Oddly, the code seems to trace properly as I step through it. I have run into strange problems before with the debugger losing sync with code, etc that were usually fixed with a clean (and occasionally a restart of Flex) but nothing I do clears this. I have found, however, that *moving* the function to some other place higher up in the file will allow it to work. I have noted also that it is not tied to a particular function, but rather their seems to be a place beyond which in my file that this problem occurs. Of course the obvious thing would be to try and isolate where that point is, and examine the code, but I cannot find anything suspicious. Has anyone seen a problem like this??

[flexcoders] Re: Resize and Save an Image
If the image is in a container, you could capture a bitmap of the container
component and save that:
import flash.display.Bitmap;
import flash.display.BitmapData;
import mx.core.UIComponent;
import mx.graphics.ImageSnapshot;
private function getSnapshotImage( component:UIComponent ):Bitmap
{
var bitmapData:BitmapData = ImageSnapshot.captureBitmapData( component
);
var bitmap:Bitmap = new Bitmap( bitmapData );
return bitmap;
}

[flexcoders] ContextMenu: is there a maximum number of menuItems that can't be exceeded?
Hello everybody,
I'm working on a snippet which must cover the lack of a column selector
or column chooser in the AdvancedDatagrid component.
I noticed that the maximum number of menuItems is 16 and the menuItems
exceeding 16 will not be shown. Has anyone encountered this issue? And
how have you solved it?

{
public function CustomDataGrid()
{
super();
this.contextMenu = generateContextMenu();
}
override public function set dataProvider(value:Object):void{
super.dataProvider = value;
this.contextMenu = generateContextMenu();
}
private function generateContextMenu():ContextMenu{
var newContext:ContextMenu = new ContextMenu();
newContext.hideBuiltInItems();
var items:ArrayCollection = new ArrayCollection();

Re: [flexcoders] Read svg file in FLEX
Hey flexlearner, What's your question exactly? How to parse XML? After you parse the XML (you can use e4x) you'll convert SVG attributes into actionscript graphics functions like graphics.lineTo(). Are you having trouble with something in particular?

Re: [flexcoders] Adobe pulls Single CPU and 100-user licenses
I am saddened by this situation... if you read a couple of posts on my blog you'll understand at least one of the reasons I left Adobe: http://blog.jvroom.com/2009/12/11/understanding-the-market-for-software-platforms/ http://blog.jvroom.com/2009/10/29/tips-for-buying-and-selling-enterprise-software/ In terms of how to go forward for customers that can't afford the new license, has anyone seen the flex 4 license for fds.swc? That gets shipped with the Flex Builder data tools and unless they changed things since I left, contains the client half of the LCDS APIs. Maybe there are restrictions in how that code can be used though? It has the hardest part of the association implementation, offline, etc. in there. If you can use all of the client features, you could emulate the server parts you use on blazeDS or GraniteDS so you can move your applications over to a different infrastructure without having pay the big license fee and rewrite your client apps. Doing simple CRUD stuff using BlazeDS would be pretty easy, in fact you can do that with FB 4 's data management just not using the assembler interface on the server. That does not do sync, associations, change batching though. The two trickiest features in LCDS2.6 were auto-sync and RTMP. If you don't need those (i.e. manual sync and long-polling are ok), it is not a huge bit of server code to replace the rest since most of that is in BlazeDS. Are there enough affect customers out there that we should start a project around this? I'm in the middle of a pretty big project of my own and so don't have a ton of time but would be happy to chip in.

Since the release of LCDS 3.0, neither of these licenses exist. This leaves our small business customers running in production using the Single CPU license with no upgrade path going forward, unless they can come up with the steep license fees for ES2. I doubt any of our customers will be able to afford it. Needless to say, this seriously impedes our ability to do business on the LCDS platform going forward in the SMB market we serve. It also leaves our hands tied with respect to the software we've already developed and deployed. BlazeDS is not an option - it would require a total rewrite of client and server, and mass annihilation of features. How are these changes affecting your business?
RE: [SPAM] [flexcoders] How to parse xml with namespaces
Namespaces are a pain. You can declare a default' namespace, assigning it http://www.w3.org/1999/xhtml;. That will give you access to the nodes without a specific namespace. Then I guess you will need to use the :: syntax for the specified namespcaces. Google this there are several detailed discussions.
