[flexcoders] Re: LinearAxis - need help with value ordering! (Repost with sample code)
That was going to be my next suggestion, create yourself an inverted
chart space and plot points in that space. You shouldn't have to
change your raw data. In your shoes I would either have a specialised
getter for your y value e.g.
public function get chartYValue():Number
{
return value+((50-value)*2);
}
and bind to that, or if you really need to, have a custom object and
probably a factory class to manage them. I have used this second
approach quite successfully.

Hi Simon,
Thanks for the reply. There are custom label functions for the
various axes, but I need my datapoints to map to reverse order as
well, so I don't think this would work.
My best hack solution right now is to force a reverse by transforming
the data in my dataProvider before charting it: in my case, I'm
charting values 0-100, so I can do something like:
invertedValue = value+((50-value)*2);
Works, but I have to change the data itself, which is going to cause
other problems.
Ely's site is fabulous, but I didn't find an answer there in my
searches.

I'd look at using a custom renderer for the y-axis labels. I'm not

a label function or something similar on the LinearAxis?
Have you poked around on Ely's blog (quietlyscheming.com)
In the extreme case you can always create your own linear axis which
handles the labelling.

Hi All,
Any suggestions on how to get a numerical y-axis to start at the
maximum value and descend on up? For example, the sample app below
starts the y-axis at zero and goes up to 5; I want it to start at 5
and go up to zero: VerticalAxis.reverseDefaultSortOrder() or
something. I've tried and failed with manipulating the
baseAtZero,
autoAdjust, minimum and maximum properties.
Any ideas, kludgey or otherwise??

[flexcoders] Re: Help! Object integrity across DataService.commit()
Thanks again Pete. So I have this in my application code which is stolen directly from the docs: mx:TraceTarget mx:filters mx:Array mx:Stringmx.data.DataService/mx:String mx:Stringmx.data.ConflictResolver/mx:String /mx:Array /mx:filters !-- 2 is represents the LogEventLevel.DEBUG constant. -- mx:level2/mx:level /mx:TraceTarget I created an mm.cfg file for myself after checking where my HOMEDRIVE and HOMEPATH were and put the following in it: ErrorReportingEnable=1 TraceOutputFileEnable=1 I re-started my server and ran the client in the debugger but I don't get any log files created. I am judiciously ignoring the instructions about log paths as you suggested. Any ideas what I have done wrong? I get a whole whack of output into the console window, but no log file. Two other questions for you (or anyone else who knows the answers): 1) where do I go to find out what the integer values of the log levels are? 2) how do I get at an object's address in memory? This may sound a little weird. What I am looking for is that piece of information which shows up in the debugger and looks like @afe634. I am presuming this is an address or an identifer of some kind and I think this is the key to me identifying what is happening to my objects. Their UIDs remain the same, but they are clearly not the same objects as their property values are different. I appear to have several managed objects with the same uid but different property values.

This is just one implementation of the ILoggingTarget API that happens to use the Flash Player trace() API. As you noticed, trace() only works with the debug Flash Player... but you don't have to actually debug to see this output (although that is a common way to do so because of Flex Builder's Console panel records this output too). The other way is to setup mm.cfg in your OS user directory to write out trace info to flashlog.txt. See: http://www.adobe.com/cfusion/knowledgebase/index.cfm?id=tn_19323 But be careful of older comments in articles like this about the property TraceOutputFileName - you can no longer customize the location of flashlog.txt. That is, from FP9 onwards this file appears in a fixed location and cannot be customized. e.g. on typical Windows XP installation, the latest player writes to: C:\Documents and Settings\username\Application Data\Macromedia\Flash Player\Logs\flashlog.txt If you just use mx:TraceTarget level=0 you'll get all events for all categories.

Oh boy, do I feel your pain... 1) Without breaking the licensing agreement I don't see any way round it 2) It is a potentially very valuable piece of technology, but I am increasingly questioning it, especially as it is is largely unproven and still pretty wobbly (and confusing). It will be interesting to see if Adobe have sharpened it all up with LCDS which is currently in beta. I hope so. meanwhile I am engineering its demise in our solution as soon as we have the absolute necessity to go above a single CPU. 3) There are some alternatives floating around. I suspect that a lot of people (myself included) will go back to their server roots and handle this all through HTTP. If you have any existing investment in that technology on your server it is almost certainly worth pursuing that route. FDS/LCDS promises a lot but between the pricing and the opacity it is a hard call to make. Personally I think that the CPU based pricing is ridiculous and is going to prevent the broad uptake of what could be a real differentiator for Adobe of they got it right. Like you I have an impossible task justifying the cost and I can't just pass it on to my customers so it cuts directly into my margin. I wouldn't mind so much if it was solid and proven, but it isn't. This whole problem stands out like a sore thumb for me in what is otherwise a truly excellent platform. Or maybe Adobe are just going to make it all open source and therefore un-licensable. With Microsoft looming, that may not be such a silly proposition. There have been other similar discussions on this board but nobody from Adobe has had much to say about it. I suspect talking about pricing on a technical board such as this is a no-no. However for those of us wearing architect and technologist hats it is a very relevant point and I'd love to hear from Product Management.

[flexcoders] Re: FDS licensing
Thanks for chipping in Matt, I appreciate your input, and I hope I have not offended Adobe PM by suggesting that they have been quiet. However, talk to the sales rep is a step that I don't believe many people will get to, especially the smaller dev shops. John and I seem to be in similar positions as technology evangelists strongly selling the merits of RIA and especially Flex but having to tack onto the end of our pitch oh by the way it costs 750/developer for the IDE and 10k/CPU when we put it into production, so someone had better call Adobe It's hard to get the conversation past that. And I'm not suggesting you are trying to rip anyone off. I also appreciate that Adobe is not a charity and has to make money like the rest of us, I just think as it stands you have a prohibitively expensive pricing policy based on a model which has been shown to be unfavourable both for my customer and me as a vendor (Adobe are not the first people to have a CPU based pricing policy for server components). It would be naive to believe that it is not excluding a portion of the software development community and a big ask that everyone who does evaulation contacts a sales rep. Like you I think you have a useful and compelling offering otherwise I wouldn't be placing a large bet on it. The reality though is that I am going to have to switch away from FDS/LCDS precisely because of the effect on my bottom line. Adobe can choose to ignore that, but I doubt I am alone.

I wouldn't mind so much if it was solid and proven, but it isn't. This whole problem stands out like a sore thumb for me in what is otherwise a truly excellent platform. Or maybe Adobe are just going to make it all open source and therefore un-licensable. With Microsoft looming, that may not be such a silly proposition. There have been other similar discussions on this board but nobody from Adobe has had much to say about it. I suspect talking about pricing on a technical board such as this is a no-no.

[flexcoders] Re: Will Microsoft's new Silverlight Player Kill our beloved Flex ?
...and therein lies another horrible truth, the MBP hardware is a winner, OS/X is not. I myself am using a MBP and it is awesome, but guess what, I'm not using OS/X (although I return for doses of sanity). My anecdotal study of the three Starbucks in walking distance from my house shows 75% of people with MBP's. Closer inspection reveals 90% running Windows. Bottom line is that (normal) people don't really care what software they are running as long as it is good enough, and Windows has made this a reality by ubiquity, not excellence. It is shameful that you need so much processing power just for the operating system, it is lazy coding, but who really cares? Ask your Mum/Mom whether she is bothered whether she uses flash or silverlight. And the previous poster was right, Microsoft do live in their own bubble and their intellectual protectionism is shocking, especially to a European mindset (why don't they just participate rather than trying to own absolutely everything?). However, when your bubble includes 85% of all computers ever built, it is understandable that life outside the bubble may seem somewhat irrelevant, especially if your goals are commercial rather than principled, which Microsoft's undoubtedly are. However, they do have a serious credibility issue in the software development community as this thread (and our avid support of Flash) is a minor testimony to. When I'm placing a trust bet I don't choose Microsoft. As a result I don't think Microsoft are going to retain their position of dominance forever as more and more becomes available through open source initiatives. But the Microsoft monster is here for now and it is smarter as a commercial software developer to use the fact to your advantage than to stubbornly attempt to ignore the reality. And speaking of the tao of programming, I think the only haiku worth remembering in commercial software is that best never wins, and neither does first.

[flexcoders] Re: Where is the data stored..?
My bet is that it is not in the datagrid at all but in the result
object from your dataservice request, i.e. it belongs to
teachernameRequest.lastResult. Is either teacherlist or teacherid an
array (one of them must be)? If you were to make an explicitly typed
model on your client side it would probably be quite obvious where the
data resided.
For this type of issue I have found it a more useful model to think of
controls like the datagrid, lists, comboboxes, etc as renderers rather
than custodians of data. It also seems to fit with the renderer
pattern to displaying data which permeates flex.
Hope that helps.

[flexcoders] Re: Will Microsoft's new Silverlight Player Kill our beloved Flex ?
Does C# kill Java? Does IE kill Firefox? Does SQLServer kill Oracle? Does Windows kill UNIX? Will Silverlight kill Flex? From my 20 odd years of software development, during which time the Microsoft hegemony has been at its apogee, none of the above are true. In fact if you want a really scalable enterprise platform you would choose the right hand side of the list above rather than the left. Where Microsoft win hands down is in Office Applications and desktop operating systems. Excel is quite possibly the best piece of desktop software ever written (Word being the worst) and long may it reign as such. Windows is crap, but it's more than good enough for your average user and most Microsoft desktop products are actually pretty good (c'mon, be generous). I regret deeply that the rest of the world doesn't have a house full of beautiful, stable, simple Macs like I do, but the reality is that they don't as Jason points out. Instead the three or four computers the normal person interacts with in their daily lives are almost exclusively running Windows (even the ATM machines and tills at the supermarket). Not a pleasant truth, but a truth nonetheless. If you are looking for broad adoption and commercial success as a software company you start with Windows. The wonderful reality, however, is that the software industry, like all others in the history of human endeavour, thrives on competition and there is space for more than one company/product/offering to survive. Adobe are not going to be Microsoft. THANK GOD! They have and in my opinion will always have, a distinct and separate offering. If they can't retain that differentiation then they don't deserve to remain in business and the market will take care of them. So this is a bit of a silly thread as far as I am concerned. The answer for me is clearly No for all the same reasons that Microsoft haven't killed any of the other things on the list at the top. They might try, but I think they should be more worried about Google and web based desktop software than Adobe and the flash player.

[flexcoders] Help! Object integrity across DataService.commit()
I seem to be getting object instances changing across a commit() boundary. Half the object ID's change through a commit for no apparent reason. This means I have no capability to manage a parent-child relationship in data. Utter disaster! Here's the situation. I have a parent child hierarchy of objects, from the root to the leaves: PO PP SS SC OP So PO's contain PP's, PP's contain SS's and so forth. I converse with a single data service which delivers a set of PO's and the PP's are thereafter lazily loaded. I don't break the dataservice or object model anywhere below that, so a PP is treated as a single entity and read and written as such with its entire sub-graph of objects. I have two destinations, one for PO's and one for PP's and this all works fine. However, when I create a graph such as the one above and commit it to the server through the PO destination I have different object instances for SS, SC and OP's after the call to commit returns. This is a problem because there are some properties which are specific to the object instance, in particular an object reference to its parent. The object instance of the parent is changing across the commit boundary. Before commit everything is joined up nicely as you would expect: PO @42f2451 PP @43f3629 parent @42f2451 SS @4c0ee71 parent @43f3629 SC @a5d69d1 parent @4c0ee71 OP @a2f5a01 parent @a5d69d1 after commit these are the same... PO @42f2451 PP @43f3629 parent @42f2451 however everything else is different SS @4c0e151 parent @a94d3d1 SC @4ba2d31 parent @4c0e151 OP @new parent @4ba2d31 what's worse is that the new parent instance of PP held on the new SS (i.e. whatever is under @a94d3d1) has itself a null parent reference. That means that after the commit my tree below SS is dangling in the wind and I cannot find the parentage up to PO! This is a complete disaster. It effectively means I have no bi-directional one-to-many support, e.g. no Parent-Child, the most basic of relationships! Worse, if I traverse down from PO to OP I cannot traverse back up again! It goes down one path and up another which ends before it gets to PO. So I have three questions: What am I doing wrong? How do I prevent my object instances from being screwed around with during commit? How do I tell when commit() has finished? Is there an Event I can trap for its completion? Then I could at least repair my tree. very glum... SP

[flexcoders] Re: Grid columns of fixed and equal width
Since you asked so nicely... here's what I understand about column widths in the datagrid control after some experimentation. First off it is the width property of the DataGridColumn that I'm talking about. If you put a value in the definition of all columns, when they get rendered the relative size of the column widths is honored, even through scaling of the width of the grid itself, so the widths seem to be treated as proportions. If you leave one or more of them blank the widths are treated as pixels as far as I can tell. What I routinely now do is have a numbering scheme for the widths where I look at the narrowest column, call that, say, 10 then do everything from there. Here is a fragment of code from my app which has nicely proportioned columns which keep their relative proportions as the window the datagrid is in changes size. mx:DataGridColumn headerText=Name width=30/ mx:DataGridColumn headerText=Owner width=25/ mx:DataGridColumn headerText=Potential width=15/ mx:DataGridColumn headerText=Target width=12 / mx:DataGridColumn headerText=% width=10 / mx:DataGridColumn headerText=Geography width=15/ mx:DataGridColumn headerText=Sector width=15/ mx:DataGridColumn headerText=Product width=15/ mx:DataGridColumn headerText=Currency width=7/ mx:DataGridColumn headerText=Access width=10/ So in your case I would be tempted to try 1, 1 and 1 for your widths and see what happens.

Any hints would be a great help in getting me going.

You are right, there is no min bubble size, and the basic transform
scales the radius, not the area of the bubble, which I find very

two different in terms of their radiusField value are actually 4 times
different in area. This confused the hell out of our users and was

[flexcoders] Re: Bubble Charts (size of the bubble)
do you have the same set of bubbles visible after your slider
magnification as before?
The default bubbleseries sizes the bubbles *that are displayed*
relative to one another based on the radius field (the series has a
display list that it uses for sizing).
If you add or remove bubbles the relative sizes of the remaining
bubbles change. They still refer to the radius field, but because
they are a different set they will have different proportions.
Do you have max and min bubble sizes set?

[flexcoders] Re: Bubble Charts (size of the bubble)
I think it would be illuminating for you to set a breakpoint in the updateTransform method of the BubbleSeries class and check out what flex is doing with renderData.filteredCache. This is what it uses to compute the bubble sizes. You are right, there is no min bubble size, and the basic transform scales the radius, not the area of the bubble, which I find very misleading. What it means is that two bubbles that are a factor of two different in terms of their radiusField value are actually 4 times different in area. This confused the hell out of our users and was logged against us as a bug. I can share an overloaded bubbleseries class with you that I have adjusted to have a min bubble size and which scales the area according to the radiusField and not the radius.

[flexcoders] Bubble charts with only one bubble
Has anyone experienced the problem of a bubble chart with a single bubble not showing that bubble? If I add a second bubble the pair appear, if I remove one of them they both disappear. I have been inspecting the contents of the renderData on the BubbleSeries. When there is a single data point in the biinding the cache contains it as a BubbleSeriesItem and the filteredCache is empty. The cache value has no x, y, z or itemRenderer set up. When a second gets added they both appear in the filteredCache and they have their values populated. I have tried various hacks like moving data from one to another and messing around with the x, y and z values myself, all with pretty disastrous effects. It seems too much of an oversight for the bubble chart to not work with a single bubble, so what am I missing?
[flexcoders] Re: Flex Installation\Compilation Guidelines for AIX OS
I should start by saying that I have not done this with flex, but I have both lead and been involved in many projects where we have had to retro-fit to IBM. The experience has been chastening and it is never a straighforward task. Have you got your AIX hardware up and running with the IBM software actually operating yet? Have you identified any expertise either internally or externally who has experience in AIX? Have you teased out of your client (or whoever is requesting this step) whether it stops at AIX or whether you need to go to DB2 and WebSphere? If not then go and do that first. I'm not sure why you would need to compile any flex code under AIX. The only reason to do that would be if your clients were running their browsers on AIX. Is that the case? The swf and html you generate in flex is piped across to the client machine and run there inside the FlashPlayer, not on the server. So I don't think you need the Flex Builder anywhere other than Windows (or maybe Mac if you prefer to work on a Mac) because your clients are probably running IE on Windows. As for the server, how you should do it and how hard your job will be will depend upon the language you have implemented your server side components in, the application server you are using and the features of your app. If you have a database my bet is the next question you'll get asked is to put it on DB2 and WebSphere, it's part of the IBM religious canon. If you have a C++ back end then you'll need to get familiar with the AIX compiler and get ready to have to change all your code. If you are C# I have no clue how you would go about it, although I bet there is a story. If you are Java you are in better shape, but watch out for differences in XML parsers and compliance to standard interfaces like SQL/JDBC. IBM are as bad as Microsoft for implementing their own versions of standards. You have done the right thing by downloading the AIX server components from Adobe. Now you need to assemble your server in whatever AIX technology is available. Get AIX releases of your app server, database etc. and get it all that stood up and running and delivering pages of any kind. You will probably find all sorts of challenges with that alone if this is your first time with IBM. Once you have done that, and presuming you have been reasonably well behaved, then in theory you should be able to recompile your Java code under AIX and it should run (in theory you should be able to just deploy the same Java component, but that is very unlikely to work). I think you have enough work just to get there. I suspect your situation will either change or become clearer once you have got to that point. Best of luck SP Unrequested editorial comment: If it wasn't for IBM strong-arming its partners, AIX/DB2/WebSphere would have been consigned to the dustbin years ago. It's not that they are really that bad - although DB2 is a bit of a nightmare - it's not even because they are very difficult and subtle and the skills are not widely available - although that is all true too, the real kicker is that there are better things out there which are either free or lower cost. The IBM blue stack only exists because IBM would look very silly taking anything else into its clients and it forces its partners and customers to comply because of its size and because it wants license revenue from its software products which it would otherwise never get. Eventually this rigging of the market will have to stop and I thought they had seen sense with their investment in Linux, but the AIX dinosaur rolls on. --- In flexcoders@yahoogroups.com, sanjaypmg [EMAIL PROTECTED] wrote: Hi All, I have developed an application for windows...

[flexcoders] Re: Flex Installation\Compilation Guidelines for AIX OS
I must be missing something obvious because I'm not seeing why you would fiddle around with compiling mxml files on the server, just put the binaries there. I think this step needs looking at: 2. Compile MXML using Flex builder on AIX. Is there a flex builder for AIX? I doubt it and I don't really see why you need it. Flex builder will generate a *.swf file for you. That swf file runs in the FlashPlayer running in the browser of the end user, not on the server. The target O/S for the swf is Windows unless your client is a very weird world of the end users having AIX on their desktop. If they do, turn the job down, change your phone numbers and run in the opposite direction very fast :-) Your application server just delivers the swf file to the end user's browser. What you do need is AIX software on the server end to respond to the requests that the swf will make back to the server. That's what you downloaded when you went and got the Adobe fds for AIX. What you need to do is get all the bits together on the AIX machine in a WAR file which will run on AIX under the application server in question. Once you have done that, then try deploying it. If you are expected to support this then you'll end up buying AIX hardware, you'll have no choice. --- In flexcoders@yahoogroups.com, sanjaypmg [EMAIL PROTECTED] wrote: Hi SP, Thanks for your quick response Though AIX hardware is up and running at client end so that wouldn't be an issue..

[flexcoders] Re: Finding / Displaying Values in a combo Box
here are some ideas...
second case first...
you could create a TermsCode object with the fields code and
description and a magic toString() function, something like this...
package blah
{
public class TermsCode
{
public var code:String;
public var description:String;
public function toString():String{return description;}
}
}
and populate it with whatever gets returned from your db call. how
you do that will depend entirely on your data access tier. Having
populated the array you can then just bind the dataProvider of your
combo to a collection of these classes and the display will be taken
from toString(). You can then either use selectedItem or
selectedObject on the combo object to manage your selection.
for the first one you have a couple of choices and you'll have to
decide how to go based on extensibility etc. of your app.
Since there are so few things in your list you could just create a
static array of strings with your descripive text in it and
stick-handle the value of the selected index based on inspection of
the text field, i.e.
if (it = A)
{
myCombo.selectedIndex = 1;
}
else if (it = B)
{
myCombo.selectedIndex = 2;
}
etc.
If you wanted to be clever you could probably create an array of
objects indexed by the value of the letter using the somewhat
mysterious object syntax
var x:Object = {}
If you are afraid to tread in those murky waters (as I am) then there
is an interesting possible alternative offered here

Subject: RE: [flexcoders] Re: question about string equality
For AS3, I think it is fine to use the new operator in general - I was
clutching-at-straws as to why something might be different in your
scenario (largely because I know in AS2 there was a difference between
and new String() as there was the concept of primitives and object
forms of the string type and the object form wouldn't serialize
correctly in AMF 0, for instance).
To be honest, I've lost track of the original question in this thread
and am not sure whether you're just looking for the best way to compare
strings in AS3 or you're trying to do more and, say, cater for a case
where you want the empty string being to be equivalent to an
uninitialized state in your program?
I know one scenario that can be confusing is this:
var s1:String = ;
var s2:String = null;
if (s1)
{
trace(s1 was true);
}
if (s2)
{
trace(s2 was true);
}
Neither of these trace statements will execute. I always avoid this
short-cut syntax because it leads to further confusion that all
non-zero-length strings evaluate to true, and a string like false will
just be seen as a String of length 0 and hence true. To be safe, I
always write the condition I'm trying to test explicitly...
if (s1 != null s1 == true)
{
//...

Good point, I didn't include the declarations.
They are both strongly typed Strings, I don't use objects anywhere in
my code.
co is a custom AS object of type Competitor, here's the declaration
of the name member:
public var name:String;
oc is a custom AS object of type ObjectCategory and here is the
declaration of the category member:
public var category:String = new String();
The strong typing answers the question about whether they just happen
to contain strings.
Other than the fact that they belong to custom objects I have written,
there is nothing peculiar about either the string variables or their
contents.
I don't think they are in a custom namespace, but to be honest I'm not
exactly sure what that means, so I can't say with certainty that they
aren't. I think the answer is no.
co.name gets populated by various means, either though a user gesture
in a custom page or by retrieval from a java data adaptor to my
server. oc.category is populated programmatically during execution of
the code in question.
I appreciate you guys looking at this. Right now I have it working as
I expect but it is a bit worrying that I need to do the comparison in
this way only in this instance. That says to me that I don't properly
understand something.
If I want to check equality of the content of two strings should I
always be testing valueOf()?

line 06 is the offending line.
if I have:
06 if (sc.name == oc.category) bFound = true;
the bFound flag never gets set true. I have to have the valueOf()
function in order for the equality to fire correctly.
This is not what I expected. I thought that regular equality would
have sufficed here since sc.name and oc.category are both Strings.
Why am I wrong and why do I need valueOf()?
[flexcoders] Re: question about string equality
Good point, I didn't include the declarations.
They are both strongly typed Strings, I don't use objects anywhere in
my code.
co is a custom AS object of type Competitor, here's the declaration
of the name member:
public var name:String;
oc is a custom AS object of type ObjectCategory and here is the
declaration of the category member:
public var category:String = new String();
The strong typing answers the question about whether they just happen
to contain strings.
Other than the fact that they belong to custom objects I have written,
there is nothing peculiar about either the string variables or their
contents.
I don't think they are in a custom namespace, but to be honest I'm not
exactly sure what that means, so I can't say with certainty that they
aren't. I think the answer is no.
co.name gets populated by various means, either though a user gesture
in a custom page or by retrieval from a java data adaptor to my
server. oc.category is populated programmatically during execution of
the code in question.
I appreciate you guys looking at this. Right now I have it working as
I expect but it is a bit worrying that I need to do the comparison in
this way only in this instance. That says to me that I don't properly
understand something.
If I want to check equality of the content of two strings should I
always be testing valueOf()?

[flexcoders] Re: Save to database
If you are connecting to a db on the server then you have a couple of obvious choices. 1. You can use the built-in capabilities of flex data services which will manage the modifications for you and only notify your server components of changes. 2. You can use an ORM like Hibernate to do the same thing between your server code and the RDBMS. 3. You can write all that code yourself. You can in fact combine any or all of them too. There are probably other options too, but one of these ought to do you. It is generally bad practice for you to be truncating your data before writing. Unless you are absolutely sure the data is that transient you shouldn't do it. I suggest you do a bit of reading about FDS in the Flex docs. Also it is probably worth picking up a book on Hibernate and giving it a thorough read, especially regarding transactions and commit strategies.

[flexcoders] Re: Accessing the parent component properties
I favour events. I have just spent the weekend switching from a (solely) central controller model to an event driven model and here's why. Every time anything happened through a user gesture which changed the state of something in the controller, every binding got updated (as you would expect). As my application became more complex this became an increasing overhead and I found myself more and more susceptible to timing issues (especially with lazily loaded server side data). I may have been doing something wrong but I had a few seconds of binding update on some changes to central pieces of data. It was only getting worse too. In addition I had liberal sprinklings of casts of parentApplication or some such back reference throughout my code to bindable variables in the central controller. It just felt wrong to be hooking up my nicely objectified components to some artefact of the circumstance in which they are being used. This is exactly the opposite way that the Java world is going with the likes of Spring and once you have reaped the benefits of that approach it is very hard to go back. I suppose I have a philosophical objection to doing that so part of my re-architecture was to remove a lot of these implementation dependencies and a nice corollary (which I think justifies my weekend working) is that I now have less code overall, some re-usable libraries and a faster app. I'm not saying that flex/AS in and of itself causes these problems but it is easy to fall back on a central controller model and it is a bit like having loads of global variables. It gets you going in a hurry but is not really sustainable. That's my experience so far anyway. --- In flexcoders@yahoogroups.com, Alex Harui [EMAIL PROTECTED] wrote: Many folks prefer a model/view or model/view/controller architecture and use databinding to hook up to a central model or controller.

[flexcoders] Re: Two-Way Binding Solutions?
You are right, it is because your model.pendingContact and
model.newContact are object references and not object instances. When
you do the assignment you are just pointing them to the same object in
memory - 2 references, 1 object. In your second case you create a
second object, 2 objects, 2 references. This is a familiar concept if
you have spent any time coding in Java.
I'm willing to bet you won't find a cloning technique that will really
suit your purposes (but then I enjoy a flutter). From personal
experience I am yet to find a use for cloning that I have stuck with.
I have used it in Java but every time I have thought it was a
solution it turned out not to be because of some logical constraint in
the data. Most likely there will be some logic implicit in the
member variables or your object (such as id's etc) that it would not
be safe to simply clone. If you have a complex object containing an
array what would you expect it to do? I generally resort to
intelligent copying and a self-impose standard interface across my
code to copy (I used to use overloaded = operators and copy
constructurs in C++ but that's the very distant past).
For the case that you cite you must be binding the individual members
of your VO to form fields to display their values. One approach is to
trap the enter key on those fields and apply the new values back to
the object. That way you only need a single object and its state is
represented by the fields in your form...
mx:TextInput id=txt_Name text={myVOContact.name} enter=saveName()/
...
private function saveName():void{myVOContact.name=txt_Name.text;}
...
You might wind up with lots of little saveX() functions but that
wouldn't be the end of the world.
Alternatively you could probably also bind the assignment directly...
mx:TextInput id=txt_Name text={myVOContact.name}
enter={myVOContact.name=txt_Name.text}/
Not every control support the enter event but there is normally some
analogue, such as a combo closing or a checkbox state changing or a
radio button being selected that will do just as well.
A third method involves putting a submit button on the page. When
clicked, manually transfer the data from the form fields to your VO
and post back to the server.
Unless you are measuring the changes in your data I'm not seeing the
value of a second object instance (yippee, no clone).

I have trying to figure out how best to accomplish the two-way data
binding needed for form entry. Here is what I thought would work,
but it doesn't seem to:
ON MODEL:
I created two variables that hold my VO.
model.pendingContact
model.newContact
The user clicks a button to get ContactVO data from the server. In
the command class I assign the result (which is a typed PHP
ContactVO) to each variable:
model.pendingContact = data.result;
model.newContact = data.result;
I then bind my form fields to model.pendingContact so that the
existing values from the server show up in the TextInput fields.
Lastly, I use the BindingUtil methods to bind the text property of
the TextInput fields back to model.newContact so that I can record
any changes and send them back to the server.
When the user submits the form, model.pendingContact should hold
the old values model.newContact should have the new values.
Correct??
Am I overlooking something. The only way I can get this to work is
if I don't assign model.newContact to the values from the server
and instead create a new instance like this:
model.pendingContact = data.result;
model.newContact = new ContactVO;
However, I can't do this because I need the newContact to start out
with the old values from the server. Is there a duplicate or clone
object method that I need to use so that both model variables can be
assigned to the same object from the server??
Thanks for the help.

[flexcoders] Suspending data bindings during (lazy) server read
I am transfering the head of a hierarchy of objects to the client for them to choose which one they want to see details for. The list returned in this initial fetch is bound to a datagrid control, and some of the data items are displayed in the grid. The rest of the data is loaded lazily through a destination via the java assembler. Once a request for the rest of the object is received I do return quite a lot of data and it can take up to 2 seconds for the response to arrive back at the client. One immediate question is how I show a progress bar or a wait cursor while this operation is occurring. In all honesty I would prefer it was synchronous but I can't seem to force that to happen. So, I have a partially loaded object and when the remainder of the data does finally show up I recalculate some of the fields that I am displaying in the orginal data grid because they may be stale. What I have found is that I get a stack overflow where the data binding manager is busy watching changes to the members of the class that I am busy re-calculating. During recalculation I get an itemPending error which causes my recalc function to be re-called which touches the bound data items which causes the data binding manager to kick off again. And round and round we go until I either run out of stack space or the server stuff returns just in time and my data show up. I have tried to separate out the activities so there is no binding during loading, but this is causing me some horrible usability issues and seems to be a bad way of approaching the problem. What's more the asynchronous nature of the server interaction is such that I can't tell when exactly I'm going to receive the data (I have to rely on trapping itemPending errors) so I don;t really know when it is safe to re-bind. What I would like to be able to do is just suspend the data bindings in the client code while the lazy loading is taking place, and then re-bind when I know I have all the data. Any hints or architectural suggestions would be greatly appreciated. SP

Is it possible for you to give a rough date when we might expect the beta to start (to which you will not be held)?

If the beta is soon I may hold off and put attention elsewhere. Any insight you could give would be greatly appreciated. Kind regards Simon Palmer --- In flexcoders@yahoogroups.com, Jeff Vroom [EMAIL PROTECTED] wrote: My apologies for the Hibernate problems y'all have been having. We do have a bunch of users happily using this for relatively simple use cases but as your domain models grow in complexity, you may run into some problems. Here are the set of problems I currently know about. 1) unique object exceptions during updateItem. The one case where I know this will happen is if you have hibernate associations which do not have corresponding FDS associations (i.e. the hierarchical values). This should be supported and it turns out that the fix for the problem is to use hibernate's merge method instead of trying to do the merge by hand as is done in 2.0.1's updateItem method. The code in updateItem that is causing the bulk of this problem is the code which fetches the current server version to do conflict detection. In doing that, it creates hibernate instances in the session which may conflict with instances that get sent in by the client. Hibernate's merge method takes care of all of this for us. 2) Domain objects need id/equals test which is based on the id. Some of the code in the hibernate assembler is using the equals method when it should be comparing the id properties. You can workaround this by having equals and hashCode methods which are based on the id. 3) Session closed errors trying to fetch associations when we are writing objects to the client. I'm not sure why the current fetchObjectProperties method is not fetching these objects for some people's domain model but if anyone has a test case which can reproduce this I'm interested. It should be walking down all public properties and fetching them - the same way that our serialization code is working but somehow I must be missing something in the traversal code. There is a public beta coming out fairly soon which will have 1) and 2) fixed. I haven't had a chance to backport these fixes to a version of the hibernate assembler which works in 2.0.1 but if there is enough demand (and I can find enough time!) I could probably do that. Of course I'd rather get anyone running into trouble on the beta so we can make sure that version is solid.

Good to hear. was just replying to your previous post in this thread,
and now I see you got it figured out. Excellent.
I still can't figure out how to turn on debug logging in Hibernate,
See this other post where I figured out how to turn on the Hibernate
logging. If you don't know about log4j, I suggest doing a few searches
on it, and reading up about the log4j.properties file. It's a very
powerful tool, and Hibernate has a TON of good logging, but its easy
to get lost in it all if you just turn everything on to debug...
http://tech.groups.yahoo.com/group/flexcoders/message/59623
Hibernate has a sample log4j.properties in the Hibernate/etc directory
The exception is thrown way down in the bowels of the Hibernate
session.save() method which is being called by
HibernateAssembler.createItem. From Jeff's last post he seemed to be
suggesting that updateItem was in some way at fault. I'm not quite
seeing how that relates to my problem, although I am clearly no
expert.
I'm not exactly sure how the problem would occur from createItem(),
but take a look at my post here I mention what was causing it for me
(was a lazy=false setting on the collection association of the object
being updated)
http://tech.groups.yahoo.com/group/flexcoders/message/63471
The issue with the NOT NULL column was that once I had everything
working the behavior it was doing was to null out all the FK values
for the association, thereby dis-associating the children from the
parent, then updating all the entries in the collection to point back
to the parent. Once I made the association nullable, the update
started working. (at least as far as FDS was concerned.
Jeff, if you have a new version of the Assembler code and want a
guinea-pig, send it my way.
Likewise!

[flexcoders] Building the FDS HibernateManager class in Eclipse
Hi, I am trying to debug the FDS HibernateAssembler. I have put the HibernateAssembler HibernateManager HibernateType java files into my own package and adjusted dependencies accordingly. I am unable to build because of the following problem. The HibernateManager.getSession() method contains the following line of code: if (!syncSession DataServiceTransaction.getCurrentUserTransaction() != null) syncSession = true; I get the following two build errors: 1) The project was not built since its build path is incomplete. Cannot find the class file for javax.transaction.UserTransaction. Fix the build path then try building this project 2) The type javax.transaction.UserTransaction cannot be resolved. It is indirectly referenced from required .class files I can't find anything which seems to contain the UserTransaction code or interface. Anyone know what I need to do to my Eclipse project dependencies to have this compile? SP
[flexcoders] Re: FDS DataService.commit() doesn't trigger responder result()...?
No answer unfortunately, but I do have two questions... 1) how do you manage to debug your server side jave code? I am running under JBoss and using Eclipse as my IDE for both Java and FlexBuilder and I can't figure out how to set breakpoints in my Java code or attach a debugger to the server. 2) how do you switch on the FDS logging? not the response you were hoping for I am sure, but you would be helping a fella out :-) SP --- In flexcoders@yahoogroups.com, parkerwhirlow [EMAIL PROTECTED] wrote: Hi again, I've got a simple save case working as far as I can tell (from debugging the server java side, everything is OK after leaving the HibernateAssembler.java updateItem() method.

[flexcoders] parent-child hierarchy of data using Flex, FDS and Hibernate
Hi, I have a 4 level hierarchy of data in my application with a bi-directional one-to-many relationship between each level as follows: PlanPoint (parent) -- UserScenario (child) Scenario (grandchild) -- Competitor (great grandchild) I have a hibernate back end running under JBoss and I am using FDS to synchronise the changes from my Flex UI. My DB will be Oracle, but for the time being I am just testing with a HSQLDB for convenience. I have managed to create a destination in FDS which will retrieve the parent objects. The hibernate mapping docs specify the further retrieval of the graph of objects attached to them. This all works fine and performs reasonably well, although I have been unable to get any meaningful lazy loading to work (a problem for another time). My problem comes in that the user will interact deeply with the graph of objects during the client session. This includes adding, removing and updating objects at all levels. What I can't seem to get right is the interaction in the Flex layer which copes with this level of interaction. For instance if I want to add a new Competitor to a Scenario do I (i) create all new objects on the client and then synchronise the server, or (ii) initiate creation of a new object on the server and then modify it on the client? I seem to have problems in both directions and the same isue for delete and to a certain extent modify. I only have a single FDS destination defined, so any alterations appear to go through the PlanPoint Object at the root of the tree and as a result much more data gets passed back and forth than I would like. I'm not sure if I am just a little simplistic in my design and need more sophistication in my relationship between the client and server, or whether I just need a bit more code in my client to manage the object state. Any guidance would be greatly appreciated as I'm beginning to swim in circles.
[flexcoders] Documentation of FDS estination metadata tag
Does anyone have any reference material on the metadata tag in an FDS destination? It is alluded to in the User Guide with some intriguing possibilities, but I can find no firm documentation or use cases. Any information gratefully received Thanks
[flexcoders] Parent Child hierarchy of objects in FDS Hibernate
I have a hierarchy of objects parent -- child grandchild -- greatgrandchild they are persisted in separate tables and mapped in hibernate as bi-directional one-to-many relationships. In flex I have a destination which retrieves the parent objects and hibernate takes care of retrieving the graph of objects which form the parent-child tree. I have a set of manages AS objects in my flex project corresponding to a simple set of pojos on the server side. I have bound the AS objects to datagrids in my flash application. If I update a parent object the alterations make it cleanly through to my DB (HSQLDB instance for testing). If I alter anything on any of the subordinate objects I get an identity error thrown by Hibernate and the update fails. I am looking for examples of parent child relationships expressed in the destination definitions for the HibernatAssembler in FDS. Anyone tried this? I can't find any fds/hibernate examples out there that aren't completely trivial.
