[flexcoders] Actionscript SAX Parser ?
Hi Flex Folks, Is there a purpose-built incremental SAX Parser component available for ActionScript? Some background (please excuse the novella): In a Flex project I shipped about 4 months ago, I needed to accommodate a web-service that can sometimes return a large amount of data. I saw that many people recommend modification of the service (or creation of an intermediate proxy) such that results are paged. For that specific project, it turned out that I could actually modify the service to produce paged output (as I had written the web-service earlier)... but I was left feeling very uncomfortable about that as a solution for a number of reasons. In most cases, I would not have the ability to alter the web-service, so I'd be forced to create a proxy service... but this has many disadvantages, the worst being that I'd have to make (a lot of) bandwidth available for the proxy to run from my own servers, despite all the data being available from third-party web-services; this has ongoing cost implications for similar projects. I found that with server-side paging, the user experience was degraded unless I also created a paged DataGrid in my Flex UI. This was a clumsy exercise as I could find no pre-built data-bound paging component independent of any existing UIComponent. My users also reported that client-side paging is very inconvenient for large datasets (I tried various page-set sizes). I did not ship a useful feature (drag and drop re-ordering of rows) as there was no way (without getting insanely complicated during drag) to drop a bound row to three pages ago near the bottom. What I *really* wanted was something I've come to rely on in past years: an incremental SAX parser. This is really standard fare in Perl/Python/Java/.Net/C++, so I'd have thought something similar was available for ActionScript. A SAX parser in combination with a WebService object and a Socket object could form a very flexible event-based WebService-like component. Alas I found nothing. The closest I came was the SAX parser included in a href=http://xmljs.sourceforge.net/;XML4Script/a; while it was ECMAScript, it looked quite tedious to port/integrate. I didn't have the time before, but I can see that it will be immensely useful in the future. An event-based parser: * offers much more flexibility in Flex UI development, * allows me to provide almost instant results/feedback to the user, * uses constant memory (a requirement for large result-sets). The SAXWebService could be a subclass of WebService, exposing another result-like event matchRow, but would return a fragment/object for each matched row in the returned XML data and would do so as soon as enough data has been received from the SOAP endpoint. All the other pieces are there; here's how a SAXWebService would work: 1. Create a WebService object internally to fetch, validate and instantiate WSDL, and to obtain an endpoint. 2. Take some user supplied matchRow query (XPath) to match a row. 3. During the send method, open a seperate Socket connection. 4. Get the URLRequest from the WebService object, serialise and send to the endpoint over the socket. 5. Set up an event FSM such that when data is received from the socket it is buffered. 6. A SAX event handler is written to match the available data against the match query. 7. The SAX parser is fed the buffer (or perhaps an offset portion of the buffer), which it parses as data becomes available. 8. The SAX parser will raise an event each time the query matches. The buffer can be optionally truncated (instead of using an offset) to enable constant-memory operation. Am I missing some wonderful existing prior art? Has no other developer requested this before? If not, I guess I'll have to find time to write it. -David.
Re: [flexcoders] render values from datagrid
Hi,
just copy and paste this code in flex builder mxml file
it will create a data grid with some data
i need to click on any element of that grid and need to reach to some
specific state.
i don't know how to do cell presssing in datagrid???
/
the same thing i did in flash like this:
sheetGrid.dataProvider = myArr;
var editGridListener:Object = new Object();
editGridListener.cellPress = function(evt_obj:Object) {
colDetails = sheetGrid.getItemAt(evt_obj.itemIndex);
// FOR ROWS: evt_obj.itemIndex
// FOR COLUMNS: evt_obj.columnIndex
for (var i in colDetails) {
if (i == Project) {
Proj = colDetails[i];
}
if (i == Description) {
Desc = colDetails[i];
}
if (i == HoursSpent) {
Hr = colDetails[i];
}
}
how to do this in FLEX

[flexcoders] Anyone doing the XULRunner + Flex thang ?
Hi Folks, I have some experience deploying XULrunner applications (standalone not .xulapp type). I've found XULrunner to be preferable to Apollo (as it stands) for various kinds of non-Flash interaction with the host system and the user. I noticed some interest in a SWFRunner project at http://osflash.org/pipermail/osflash_osflash.org/2006-February/007659.html but it looks like this has not really developed any further. Is anyone else doing this? Care to share your experiences? One of the major concerns in that thread was that one can't distribute the Flash plug-in without a license from Adobe (fair enough). My *ugly* *hack* work-around was to also ship the useIEforThisFrame FireFox extension and have the Flex application run in the IE frame. That way, in the unlikely event that the user does not have the Flash ActiveX component installed on their system (or has version 8 or below), the standard install plugin page appears and the user can continue by installing it then moving on (didn't need to restart XULrunner). I feel sick re-living this tale of woe. Is is legal/ethical to detect flash (presence/version) in XULRunner and - if not found - download and install the NSplugin version of the Flash plug-in? Perhaps if a normal browser window was launched to take the user to the appropriate page on the Adobe's website automatically (where they can accept the license terms)? -David.

fyi, content added from updateDisplay You may know this or you may not but, you do not addChild() in updateDisplayList(). You would do that in commitProperties(), then update displayList() will be called to size you new children.

The way I solved it was by using a custom label function for each
column. Instead of specifying a dataField, you define the following
function inside a script tag:
function myCustomDataLabelFunction(item:Object,
column:DataGridColumn):String
{
return item.product.name;
}
Then you declare the column like this:
mx:DataGridColumn labelFunction=myCustomDataLabelFunction
headerText=Product/
Basically, your label function gets invoked on each item, when the
column needs to know what to display on that row. And you have to
return the value you want to be displayed.
I hope this helped,
Andrea.

H, still baffled. I tried as you suggested and still can't seem
to save the xml. Also, you said they do save the data type of a
complext Did you mean they do NOT save the type and when you
read it back you just get type Object? I thought that's what I read
in the user guide and that you need to use something called
registerClassAlias if you want to store a type. I tried looking
into this also and don't understand how to use this correctly. I'm
starting to get frustrated.

Also I use SO as well and they do save the data type of a complex

[flexcoders] Help with my first Flex App...
This has got to be a simple one. I am writing the tiny app given in
a video tutorial by Sho Kuwamoto. The tutorial is on displaying
flickr pictures in a basic tilelist control and is located here:
http://labs.adobe.com/technologies/flexbuilder2/tutorials/sho_kuwamoto
/
I have identified these KEY points:
1. An HTTPService call, of which mine looks like this:
mx:HTTPService id=service
url=http://api.flickr.com/services/rest/?
method=flickr.photos.searchamp;api_key=f09abdbe2fada94609244a5de3f4b8
deamp;per_page=9amp;tags={input.text}/
2. I call the web request with a button click like so:
mx:Button x=262 y=18 label=Find id=button1
click=currentState='Results'; service.send()/
3. Finally, the data provider for the TileList control in the
tutorial is:
dataProvider={service.result.rsp.photos.photo}
However, while watching the video, as he types services. he gets
two options, result and resultFormat, however, I am only getting
an option for resultFormat? This is leading me to believe that
maybe the .result property has been removed??? And that is why my
application fails?
The end result is that I have this thing setup identical to the
tutorial but it just won't do anything on the results display. The
only thing that is different is that I went to Flickr and created my
own account and search feed at
http://www.flickr.com/services/api/explore/. (This is exactly the
method used to create a feed in the tutorial)
I have uploaded the project bin folder here:
http://brad.melendy.com/code/flex/flickr/Flickr.html
I'd love to see this work and it looks so easy in the video (15
minutes!) but I've spent several hours on this now to no avail.
Thanks for any help out there

[flexcoders] crossdomain.xml security issues
I'd like to create a simple Flex application that can be distributed to any (ie. untrusted) source that reads data from my web server using AMFPHP. I understand that this requires a crossdomain.xml file. I'm trying to get my head around the security implications of open (ie. allow all) crossdomain.xml files. Basically I understand that issues arise when there is an open crossdomain.xml file on a domain that uses cookie/session-based authentication as the SWF can read/forge the cookie info that is sent in the HTTP header. This allows cross-site forgeries and other unintended consequences. My main concern is with server security though. What are the implications as far as compromising the security of the server aside from cross-site forgeries? The Adobe article linked below suggests that crossdomain.xml files may allow access to other private severs on a network which is obviously quite serious. If I understand correctly, a lot of the risk can be mitigated by hosting the crossdomain.xml file on a separate sub-domain from the domain with the user authentication mechanism. Is this as straightforward as setting up an Apache virtual host for a sub-domain which hosts a simple PHP script/gateway that forwards/returns requests to the domain which contains the data source? How have others got around this problem? Can you provide me with a brief explanation of your solution. Cheers, Darren.

[flexcoders] Tree can't render properly XML data containing two similar text nodes
Hi there,
There must be something terribly wrong with the Tree component. Here
is a very basic Flex app sample in which I try to have a Tree
component render some very basic XML data.
The trick is that in this XML, two text nodes have the same value (a
in my exemple). I can't see why this would be any problem. However,
when you fully expand the Tree, you'll notice that you just can't
rollOver and select one the nodes. You may rollOver and select a first
node, but when trying to roll over the other one, the Tree highlights
the other node, and you cannot select it at all!
It looks like for the Tree, there was only one XML instance for this
text node, and that both itemRenders rendered this same object.
I understand this might have to do with the fact that XML objects are
compared by value, not by reference (unlike as2 XMLNodes if I remember
correctly):
var n1:XML=new XML(item/);
var n2:XML=new XML(item/);
trace(n1==n2);// output:true
Note that this is just one of the numerous bugs I encountered when
dealing with the Tree component and XML. But I chose to post on this
one because it's pretty basic.
Any help or comment would be much appreciated!
Please tell me that I got something wrong and that the Tree component
isn't actually broken...
:)

Hi Barrie, thanks for the response. In terms of collaboration, anything will do. I tried a great example using Flash Media Server 2, which was a chat client. Each client was informed when a new client joined or typed a message. That's exactly what I was looking for, as we created one the other week that was based around polling. It worked, but it wasn't elegant. The price tag on FMS seems steep too (not compared to FDS!). $4000 for 150 concurrent users? Or more users if you throttle their bandwidth. The ideal solution for me would allow data-push and be able to communicate with ASP.NET. I have looked at WebOrb, but again, $10,000 per CPU is a little high.

Mark, I'm nowhere near the expert that Tom or others here are on this subject ... ... and there are some good blog posts around (and the Adobe site itself) with decent detail on all of it ... but... I work at a university and they're forever going on about collaboration, whether it's research partners, academics or student teams. I'm hunting for a project to put this into practice... (in a nutshell) both remoting and webservices follow the typical request/response. so any sync'ing of data needs polling so the clients can find out if server has new changes. but FlexDataServices (or LiveCycle DS now-a-days) has a handle back to each client from the server so it can push events/notifications telling the clients that the server's data has changed. this gives a pretty powerful hub-type configuration where one client commits updates on the server which can be sent back to all the other clients in a heartbeat. however, this is NOT peer-to-peer collaboration. the server is definitely in the middle of it all, receiving and broadcasting to subscribers. Which is OK if the data/documents/whatever is to be persisted and managed on the server. Keep in mind, that sort of technology isn't cheap - not compared to webservices... I'm no expert on all of this and I've got my own issues trying to work out how flex can do true peer-to-peer collaboration (no FDS). I'm also unsure what the upgrade path will be with our FlashMediaServers (FMS) while I wait for ColdFusion8 (and it's reported LCDS and FMS integration). but I do hope that's helped somewhat. Others can chime in with much better replies. this is just something quick to help lift the fog. what sort of collaboration do you need to do?

This is my xml: list month month=3 year=2007 day date=01 impressions=407/ etc... /month month month=4 year=2007 etc... day date=30 impressions=657/ /month /list More months will be added with time so I need to set a variable always with the values of the lastest month: endDate = new Date(2007,5,30) Accessing the beginning of the month is easy enough: startDate = new Date([EMAIL PROTECTED],[EMAIL PROTECTED],[EMAIL PROTECTED]); But how to get to the last node attributes if the last mode is constantly changing? Thanks for any help, Moca

XP, OSX, and Vista only ... leaving out millions on 98 (of course), ME(ppaaaeee), Win2k, Linux, etc. but really is that an excuse not to foster a healthy hosted Flex Data Services Ecosystem. I need to create a powerful, scalable RIA that can serve thousands of users ... probably only a few hundred simultaneously. And I don't have a lot of money ...

[flexcoders] Showing item roll over color in a data grid manually
Guys, We are having a data grid and a pie chart which show the same data. What we want is when user does a mouse over (or item roll over) over a wedge in pie chart, then the corresponding row in data grid should also show a itemRollOver color and vice versa. Any suggestions will be appreciated. Regards, Sandeep
[flexcoders] Tree and XML data containing two similar text nodes
Hi there,
There must be something terribly wrong with the Tree component. Here
is a very basic Flex app sample in which I try to have a Tree
component render some very basic XML data.
The thing is that in this XML, two text nodes have the same value (a
in my exemple). I can't see why this would be any problem. However,
when you fully expand the Tree, you'll notice that you just can't
rollOver and select one of the nodes. You may rollOver and select a
first node, but when trying to roll over the other one, the Tree
highlights the other node, and you cannot select it at all!
It looks like for the Tree, there was only one XML instance for this
text node, and that both itemRenders rendered this same object.
I understand this might have to do with the fact that XML objects are
compared by value, not by reference (unlike as2 XMLNodes if I remember
correctly):
var n1:XML=new XML(item/);
var n2:XML=new XML(item/);
trace(n1==n2);// output:true
Note that this is just one of the numerous bugs I encountered when
dealing with the Tree component and XML. But I chose to post on this
one because it's pretty basic.
Any help or comment would be much appreciated!
Please tell me that I got something wrong and that the Tree component
isn't actually broken...
:)
Here's the MXML (bug found when compiled with Flex Builder 2.0.1, Mac
OSX and Win XP. Hotfix2 didn't fix anything):

[flexcoders] Object to XML
Hi folks...
Anyone knows if is possible to do something like the XStream on flex?
That means convert an object directly into a XML, without manual work.
Class:
package test {
public class TestObject {
public var a: String = a paramater;
public var b: String = b parameter;
}
}
When I convert to XML result me something like:
test.TestObject
aa paramater/a
bb parameter/b
/test.TestObject
The problem is this XStream lib is for Java, not for flex.
Any light?

[flexcoders] My problems with Events
Hi, I'm doing a little application example while learning different topics. I'm in the Events topic now ,which I'm still struggling to understand (Capture, bubble phases). The application is very simple having a display list as follows. MainSprite ChildSprite TextField The Child Sprite has a certain dimension width, height. It contains the Text Field, width also dimension set smaller than Child Sprite. I've added an EventListener to the Child Sprite, the Event type is CLICK. The event handler will change the backgroung of the Child Sprite. The problem is that the event is triggered only if the mouse pointer enters the TextFiled area, which is a non expected behaviour. The Event should be dispatched as soon as the mouse pointer enters the Child Sprite area. Can please someone explain brievely if this is the correct behaviour and what should I do to trigger the handler event as soon as the mouse pointer enters the Child Sprite are, not until it goes the the text field area. Thanks

Re: [flexcoders] Flex and Flex Data Services Hosting .... Silverlight is coming ...
I haven't read the FDS license agreement. That said, you can get a dedicated box for relatively cheap and many such plans allow you to install whatever you want on the box. In such a case, I would expect you to be able to install FDS w/o any problems. If you only need a single Flex app on the server, you can use the free version of it. This approach is not the same as a $3 a month shared PHP / MySQL hosting, but I suspect that FDS is not geared towards that market. Joseph S. Terry, Jr. wrote: OK. Adobe...

[flexcoders] still missing flashlog.txt on OS-X
another article on how to get the trace output in firefox (or console.app): http://www.visible-form.com/blog/view-trace-statements-in-the-terminal-on-os-x/ BUT... I don't get it. I'm *sure* I installed the debug player when I installed Flexbuilder a couple of months ago and sure enough, when I write crap Flex code, the flash player tells me (more or less) what I did wrong on runtime errors. AND I've just re-installed it again, based on the articles. but I'll be blowed if I can find flashlog.txt anywhere. The /Library path is correct up to (just before) /Logs and then it's all wrong. but /Users/username/Library/Preferences/Macromedia/Flash\ Player/ must be correct `cos that's where my LocalSO's are. where's my flashlog.txt? it's not where it should be but I can't work out why not... frustrating.

I think i found the answer...
This code forms a component used in an accordion has as it child,
there are two of these in the accordion. whats happening is when the
accordion is created the child hidden gives me this error, while
visible one works fine ...
i think that until this second child is visible, the repeater (rep)
never gets a valid instance and the 'arrivedDS' function can't do its
thing.
any ideia about how to solve this???
some help would be excellent
thanks a lot

[flexcoders] Struggle with TileList refresh
I have a tileList that does not update its itemRenderer when the
dataProvider is changed. In one scenario I have a drag and drop to the
TileList that always updates the dataProvider (XMLList) but will not
reflect the change in the display. I can force a refresh by iterating
over the XMLList like so after a drag/drop event
**workaround***
var n = screensList.length()
for(var i:int=0; i n; i++){
IList(navScreens.dataProvider)[i].displaySeq = i
}
Okay that works, the TileList gets refreshed, although I would expect
there is something I am missing that would do this automatically.
Scenario 2
I created a new state that presents a small editing window to change
the data for items in the same TileList - this works fine for changing
the data directly in the dataProvider(XMLList). When the state is
returned to baseState the TileList once again does not refresh - If I
click on the item just edited and reopen the editor all the changes
appear in the editor window !. Trying the workaround used in Scenario
1 does not refresh the list.
Is there not a fool-proof method to force TileList to always reflect a
change in its dataProvider ?
Re: [flexcoders] Re: y nobody replies to my mails :(
It looks to me like people are responding to your questions. Maybe they're not going through. Otherwise, a few bits of advice (some of which you're already doing). 1. Make sure emails only have one question or all questions in the email are related to each other. This just makes it easier for someone to organize their response. (If the questions are really simple then this one probably doesn't matter as much.) 2. Posting code examples is good. Posting long code examples are bad. No one's going to read through hundreds of lines of code for you. Try and cut down example code to a simple case. 3. Make it obvious through the subject and/or the first few lines what part of the framework the problem deals with. People on this list have specialties and you want to make sure that the people who know how to help actually read the email.

Subject: [flexcoders] Help with my first Flex App...
This has got to be a simple one. I am writing the tiny app given in
a video tutorial by Sho Kuwamoto. The tutorial is on displaying
flickr pictures in a basic tilelist control and is located here:
http://labs.
http://labs.adobe.com/technologies/flexbuilder2/tutorials/sho_kuwamoto
adobe.com/technologies/flexbuilder2/tutorials/sho_kuwamoto
/
I have identified these KEY points:
1. An HTTPService call, of which mine looks like this:
mx:HTTPService id=service
url=http://api.flickr. http://api.flickr.com/services/rest/?
com/services/rest/?
method=flickr.photos.searchamp;api_key=f09abdbe2fada94609244a5de3f4b8
deamp;per_page=9amp;tags={input.text}/
2. I call the web request with a button click like so:
mx:Button x=262 y=18 label=Find id=button1
click=currentState='Results'; service.send()/
3. Finally, the data provider for the TileList control in the
tutorial is:
dataProvider={service.result.rsp.photos.photo}
However, while watching the video, as he types services. he gets
two options, result and resultFormat, however, I am only getting
an option for resultFormat? This is leading me to believe that
maybe the .result property has been removed??? And that is why my
application fails?
The end result is that I have this thing setup identical to the
tutorial but it just won't do anything on the results display. The
only thing that is different is that I went to Flickr and created my
own account and search feed at
http://www.flickr. http://www.flickr.com/services/api/explore/
com/services/api/explore/. (This is exactly the
method used to create a feed in the tutorial)
I have uploaded the project bin folder here:
http://brad. http://brad.melendy.com/code/flex/flickr/Flickr.html
melendy.com/code/flex/flickr/Flickr.html
I'd love to see this work and it looks so easy in the video (15
minutes!) but I've spent several hours on this now to no avail.
Thanks for any help out there

Re: [flexcoders] RangeError: Error #2006: The supplied index is out of bounds.
try this:
var numChildren:Number = canvas.numChildren -1;
for (var i:int = numChildren; i = 0; i--) {
if (canvas.getChildAt(i).visible == true) {
canvas.removeChildAt(i);
}
}
You were having 2 problems. First, let's say that you have 7 children and
remove 5. By the end of the loop, the child with the highest index will
have an index of 1 (0 indexed), yet the loop will be trying to access the
child at 6. Since the child indexes only go up to 1 this will throw a range
error. If you go from the highest index down, you will always be inside the
legal range because you can't remove faster than you decrement the counter.
The second problem is this: Let's say you had children A, B, C at indexes
0, 1, 2. You remove child and index 0 and then increment your counter.
During the next loop the children will be B, C and the child at index 1 is
C. You've missed checking B. If you go from the highest index down, you
don't have this problem.
I don't think I explained this very well. Every once in a while the verbal
part of my brain stops working well with code. Hopefully it was good
enough.

[flexcoders] Linux Flash Player 9 buggy ?
Hello folks, I finally made my switch to GNU/Linux. It has been an awesome experience so far (both in terms of fun and learning). I'm using Ubuntu 7.04 (Feisty Fawn). However, I found out that the Linux version of Flash Player 9 appears to be somewhat buggy. It starts with the context menu, though not a bug in itself, its appearance is kind of ugly and out of context. Then, in the official adobe website, the dhtml drop-down menus appear below the flash header. This is more another one of the please, support gnu/linux at once! messages. Please, provide native Linux support for the Adobe family of software - PS, FB, FL and so on. The FUD that Linux users don't pay for software is certainly not a fact. The Linux world has changed and is constantly changing. Many Windows users are making the switch to GNU/Linux for various reasons. It is currently a very good alternative to Windows and I'm sure many flash developers are currently using it. I just feel that Adobe currently only fills some gaps and don't treat the problem from the root. The lack of Linux Flash Player releases for quite some time is an example of it. Marcelo.

RE: [flexcoders] Help with my first Flex App...
When referenceing in AS, use result, when binding, use lastResult:
dataProvider={service.lastResult.rsp.photos.photo}
But I strongly advise using a result handler instead of directly
binding. It is much easier to debug with a handler. I also advise
using resultFormat=e4x Default is mx:Object.

Subject: [flexcoders] Help with my first Flex App...
This has got to be a simple one. I am writing the tiny app given in
a video tutorial by Sho Kuwamoto. The tutorial is on displaying
flickr pictures in a basic tilelist control and is located here:
http://labs.adobe.com/technologies/flexbuilder2/tutorials/sho_kuwamoto
http://labs.adobe.com/technologies/flexbuilder2/tutorials/sho_kuwamoto
/
I have identified these KEY points:
1. An HTTPService call, of which mine looks like this:
mx:HTTPService id=service
url=http://api.flickr.com/services/rest/?
http://api.flickr.com/services/rest/?
method=flickr.photos.searchamp;api_key=f09abdbe2fada94609244a5de3f4b8
deamp;per_page=9amp;tags={input.text}/
2. I call the web request with a button click like so:
mx:Button x=262 y=18 label=Find id=button1
click=currentState='Results'; service.send()/
3. Finally, the data provider for the TileList control in the
tutorial is:
dataProvider={service.result.rsp.photos.photo}
However, while watching the video, as he types services. he gets
two options, result and resultFormat, however, I am only getting
an option for resultFormat? This is leading me to believe that
maybe the .result property has been removed??? And that is why my
application fails?
The end result is that I have this thing setup identical to the
tutorial but it just won't do anything on the results display. The
only thing that is different is that I went to Flickr and created my
own account and search feed at
http://www.flickr.com/services/api/explore/.
http://www.flickr.com/services/api/explore/ (This is exactly the
method used to create a feed in the tutorial)
I have uploaded the project bin folder here:
http://brad.melendy.com/code/flex/flickr/Flickr.html
http://brad.melendy.com/code/flex/flickr/Flickr.html
I'd love to see this work and it looks so easy in the video (15
minutes!) but I've spent several hours on this now to no avail.
Thanks for any help out there

Subject: [flexcoders] Struggle with TileList refresh
I have a tileList that does not update its itemRenderer when the
dataProvider is changed. In one scenario I have a drag and drop to the
TileList that always updates the dataProvider (XMLList) but will not
reflect the change in the display. I can force a refresh by iterating
over the XMLList like so after a drag/drop event
**workaround***
var n = screensList.length()
for(var i:int=0; i n; i++){
IList(navScreens.dataProvider)[i].displaySeq = i
}
Okay that works, the TileList gets refreshed, although I would expect
there is something I am missing that would do this automatically.
Scenario 2
I created a new state that presents a small editing window to change
the data for items in the same TileList - this works fine for changing
the data directly in the dataProvider(XMLList). When the state is
returned to baseState the TileList once again does not refresh - If I
click on the item just edited and reopen the editor all the changes
appear in the editor window !. Trying the workaround used in Scenario
1 does not refresh the list.
Is there not a fool-proof method to force TileList to always reflect a

[flexcoders] Re: Bindings, E4X, and bindProperty()
On 5/25/07, Justin Patrin [EMAIL PROTECTED] wrote:
I'm just getting to the point in my flex application where I'm trying
to implement binding between my model and view. I've set up
bidirectional binding in the model and UI by setting a binding in
each. The model uses normal object syntax to bind to the value of a UI
element and the UI element uses E4X to bind to a node in the XML
model.
This works great when I'm using curly braces to define the bindings
directly in the MXML. I get changes in the UI to propagate instantly
to the model and changes in the model to propagate instantly to the
UI. Great, I can now both save a load my data.
The UI element looks like this:
mx:TextInput id=firstName required=true
text={model.personal_stuff.question.(@page_id ==
'personal_page_1').ApplicantFName}/
The problem comes when I need to define my bindings in a different
way. Currently many of my UI elements are defined in generic
components which will be used in multiple applications with different
models. I need to be able to set the bindings differently for
different uses of the component. I though, no problem, I'll use a
Binding tag.
mx:Binding source=model.personal_stuff.question.(@page_id ==
'personal_page_1').ApplicantFName.toString()
destination=firstName.text/
This works fine if it's set up in the component that holds this
element, but if I put it in an extended component, Flex fails with a
runtime error about multiple child sets. Now, I can put this binding
tag in the MXML where I'm including this component but I'd rather not
so that I can make my code more modular and maintainable.
The last option is to do this through ActionScript so I've tried to
use BindingUtil to set up the binding. The obvious methods didn't work
as E4X doesn't seem to be supported in the string syntax of the
binding chain but it does seem to be possible to use the getter
methods to get the value as well. The following will vause the correct
value to be loaded into the UI element but only initially:
public function getTT(personal_stuff : XMLList) : XML {
var node : XML = personal_stuff[0].question.(@page_id ==
'personal_page_1')[0];
return node;
}
public function getName(h : XML) : String {
var n : XML = h.ApplicantFName[0];
var s : String = n.toString();
return s;
}
BindingUtils.bindProperty(firstName, text, model, [personal_stuff,
{name: question, getter: getTT}, {name: ApplicantFName, getter:
getName}]);
However, further changes to the model's value don't cause the UI
element to be updated.
I'd love some help with this as the bindProperty's complex methods
(through the chain and with the getter functions) don't have too many
examples. For now I'm likely going to go with setting the Binding tags
in my main Application where these pages are defined but I would like
to know ow to make the AS version work as well, for future reference.
*Bump*, anyone else doing binding with E4X or XML structures?

If I understand correctly, a lot of the risk can be mitigated by hosting the crossdomain.xml file on a separate sub-domain from the domain with the user authentication mechanism. Is this as straightforward as setting up an Apache virtual host for a sub-domain which hosts a simple PHP script/gateway that forwards/returns requests to the domain which contains the data source?

Okay that works, the TileList gets refreshed, although I would expect
there is something I am missing that would do this automatically.
Scenario 2
I created a new state that presents a small editing window to change
the data for items in the same TileList - this works fine for changing
the data directly in the dataProvider(XMLList). When the state is
returned to baseState the TileList once again does not refresh - If I
click on the item just edited and reopen the editor all the changes
appear in the editor window !. Trying the workaround used in Scenario
1 does not refresh the list.
Is there not a fool-proof method to force TileList to always reflect a
change in its dataProvider ?

[flexcoders] How to get the target node in dragEnter()
I need a reference to the tree/xml node that is the current target of a drag/drop operation from within dragEnter. All of the examples I see use calculateDropIndex and set the selectedItem, but I do not want to select the tree item on dragOver. How can I tell what the drop target node is? Tracy
Re: [flexcoders] Struggle with TileList refresh
Yes I think my XML is well formed - not sure how to trace the overrides set
data()
Interestingly I did find that if I change the TileList display dimensions to be
very small then restore to original size this obviously forces the itemRenderer
to refresh - there's gotta be a better way to force it without using a resize
effect.

And you are using the XML api (appendChild, etc.)

H after rewriting the process to use XML the result is the same.
itemRenderer just will not refresh its display while the underlying XML
dataProvider is actually modified.
I'm about to abandon the TileList in favor of a AS created display array
after
spending 2 days on what should be a simple implementation. I still
believe
there's a simple solution - something I am missing.

Instead, use XML, or XMLListCollection.

Subject: [flexcoders] Struggle with TileList refresh
I have a tileList that does not update its itemRenderer when the
dataProvider is changed. In one scenario I have a drag and drop to the
TileList that always updates the dataProvider (XMLList) but will not
reflect the change in the display. I can force a refresh by iterating
over the XMLList like so after a drag/drop event
**workaround***
var n = screensList.length()
for(var i:int=0; i n; i++){
IList(navScreens.dataProvider)[i].displaySeq = i
}
Okay that works, the TileList gets refreshed, although I would expect

This doesn't mean having a compliant SAX parser with it would hurt - to the contrary. If anyone would like to help me on this (greatly apprechiated), please feel free to contact me directly.

Hi everyone, Is it possible to have two area series, stacked on top of each other, superimposed (overlaid) to a line series? The idea is to have the area chart stacked and the line series appear in front of the stacked area chart. Thanks, Ivan.

Re: [flexcoders] show value in combobox
Kanu,
It is not recommended to use scalar values into your dataProvider, instead
use the format {label:varun},{label:manav} instead of using varun, manav
... etc.
For solving your issue, use the selectedItem property on the combbox.
thanks
Harish
