[flexcoders] Controlling access to a Flex program...

[Laurence]

I have a Flex program that I only want users to be able to access if they're 
already inside a different Flex program I wrote, or inside a web-page on my 
server.

Is there a way, within that Flex program to which I want to restrict access, to 
tell the URL or server *from* which it was called?

In other words, If someone types 
http://www.mydomain.com/MyRestrictedFlexProgram.html directly into their 
browser, I want the program to tell the user they don't have access -- BUT if a 
different Flex program (or a web-page) on my server calls that URL, I want my 
restricted-access Flex program to go ahead and run normally...

Thanks for any help you can give me.

[flexcoders] Flex 4.6 Image Panning and Zooming

[Laurence]

I'm working with Flex 4.6, and I'm trying to allow a user to pan and zoom an 
image that's larger than the display-window...

I've found a couple of Pan|Zoom utilities (Adobe FIG Pan|Zoom and OpenZoom), 
but they're both written for versions of Flex that long pre-date Flex 4.6...

Anyone know where I can find information on how to do this in Flex 4.6?

[flexcoders] Libspark QRCodeReader library, mobile devices, Flex 4.6...

[Laurence]

Has anyone ever gotten the LibSpark QRCodeReader library to work with Flex 4.6 
on a mobile device?

The LibSpark library I'm talking about can be found here:
www.libspark.org/wiki/QRCodeReader/en

I'm trying to get this thing to work in Flex 4.6 as part of a mobile project, 
and when I run it on the desktop emulator, it seems to work fine...  But when I 
run it on the device itself, I get the following error on line 63 of the file 
AdaptiveThresholdFilter.as

Error #1010: A term is undefined and has no properties.

Now, I'm pretty certain this is being caused by the fact that said term should 
be imported from a file called adaptiveThreshold.pbj that is part of an Embed 
statement located earlier in the AdaptiveThresholdFilter.as file.  For whatever 
reason, said file is not being included in the package when I export the app to 
the device, and thus can't be found when I run the program on the device, and 
the app fails...

The Embed statement on line 40 looks like this:
[Embed(source=adaptiveThreshold.pbj, mimeType=application/octet-stream)]

So -- what I need is one of three things:
1) tell me how to force Flash Builder 4.6 to include that file in the packaging 
of the whole mobile app, or
2) tell me how to force Flash Builder 4.6 to actually embed the file within the 
program itself.  Is there something wrong about the above Embed statement that 
would be causing the app to look for the file during run-time? or
3) tell me I'm completely wrong in what I've assumed about this .pbj file 
embed-statement, and you've gotten this LibSpark QRCodeReader stuff to work on 
a mobile device, and you have source-code that I can look at.

Thanks for any help y'all can give,

I wasn't clear before -- I don't know the width of the VBox beforehand.  I was

But the measureText() method worked perfectly for me, thanks.

[flexcoders] AIR and Printing...

[Laurence]

I could really use some major advice here.  We're so close to the finishing 
point on this project, and we're being held back by stupid printing problems...

We have to be able to print with no pop-up dialog boxes, and the choice of 
which printer to send the job to will be affected by the data (i.e. a client 
with reg-code X gets printed on printer-1 and a client with reg-code Y gets 
printed on printer-2.)

We have to automate this, because the temp-workers we hire can't be counted on 
to remember how do it correctly.

So...  Any ideas on how I can deal with this?  Should I dump Flash Player and 
switch to AIR?  Would that give me better control over the printing?  Can AIR 
actually do all that I'm asking for here?  What will switching to AIR mean for 
accessing our data from our ColdFusion/SQL server through https:, if anything?

The installation/authorization stuff I can deal with...  Not being able to

I can find surprisingly little information about printing in AIR -- it's almost 
like printing was an afterthought for Flex and AIR.

Exactly how much more control over printing does AIR give me?  Can it print 
everything without pop-ups?  Can it control which printer the app sends the 
print-job to -- again, without pop-ups?  Those are the two main things I need.

[flexcoders] Re: AIR and Printing...

[Laurence]

It does seem, from reading that document, that you can choose the printer to 
send the print-job to, and set the parameters for that printer, and skip all 
the dialog boxes...  I'll have to play with that...  Thanks!

My next question, then, is accessing remote data -- my Flex app using the Flash 
Player has no problem calling a remote ColdFusion function to grab data from 
the SQL server, and send data back there...  How much does that change in AIR?  
Or is it pretty much the same thing?

 There are lots of new printing features in AIR2.0 which may be why there 
 isn't a lot of searchable info.  The link I supplied implies that in AIR 2.0, 
 you set the PrintJob.printer property to a printer and call PrintJob.start2() 
 to skip the dialogs.  Not sure how it will work on all platforms so give it a 
 try.
 
 Plan B, I think, is to generate a bitmap of the page and upload it to a

 local ones.

[flexcoders] Printing without the pop-up window...

Is there a way to get a Flex program to send a print-job to the default printer 
without it popping up that window where you select the printer and click the 
print button?  I'd really like to be able to do that.

Is that even a function of Flash-player?  Or is that built-in to the browser?

Frankly, I figured all this flap over Flash was because they wanted to try to 
force Adobe to make Flash-player open-source...  And now you're saying that 
even if Adobe does that, they still won't allow Flash on their devices?  That's 
stupid and stubborn of Jobs...

And besides, if I own a device (I don't own any Apple devices, but if I did) I 
should be allowed to run whatever software I want to on it.  It's MY device, 
not his.  I own it, not him -- if he wants to give me one, and pay the monthly 
service for it, then he can tell me what I can run on it.  Only then.  
Basically what Jobs is doing is screwing himself out of any potential business 
that I would ever give him.  (For the project I'm working on now, we had plans 
to purchase about 50 iPads to use on-site.  That's not gonna happen now...  
Glad doin' business with you, Steve -- we'll be buying Google or Dell tablets 
when they are available.)

And it also pisses me off that everyone talks about video on Flash, as if 
that's the only thing it does.  Jobs is singlehandedly ruining OUR jobs as Flex 
developers.  That's really what it boils down to -- he's trying to put us out 
of business.  We already can't write apps for Apple's portable devices -- and 
when he cuts off Flash support in OSX, there goes every Mac in the world.

It's gonna be a hell of a lot more than just 3 portable devices, when Jobs

Macs out there...

The whole reason I chose to learn Flex is that it (at the time) ran on every 
available platform.  It was THE cross-platform language to learn.

 
 You're annoyed because you're being shut out of a market you want to be in, 
 but your arguments as to why you should be allowed into that market are 
 specious. 

My arguments are not specious -- I *was* a part of that market at one time.  
I'm being shut out of a market through NO FAULT OF MY OWN.  Every Apple product 
in the world will soon have zero support for Flash -- that's NOT what I signed 
up for when I learned Flex.  The MAIN REASON I learned Flex was for its 
cross-platform capabilites.  I never had to worry about what system my programs 
were running on.  Now Apple is gone from that equation -- ergo 25% of my 
customers just disappeared, unless I can get them all to buy PCs.  Thanks, 
Steve!

 
 If you buy an iPod/Pad/Phone, you buy it as is, knowing what it can and can't 
 do. It can't do Flash. If you don't like that, don't buy the device, it's 
 really very simple. If you want to hack it to make it capable of running 
 Flash, then sure, go ahead, no-one is going to sue you. You might not be able 
 to claim on your warranty or update the OS once you do that but, yes, it's 
 your choice if you want to go that way. Most people don't because most people 
 can actually live without Flash, believe it or not.

I agree with you here -- knowing in advance that it doesn't run Flash is a good 
thing, and people can then make a choice accordingly.  It just really angers me 
if I were to own a device and some entity somewhere tells me I cannot run my 
own software on it.  I would be ranting against MS or Linux just as angrily, if 
they were to suddenly come out and say I couldn't run a particular piece of 
software just because they don't like it anymore.  (And, yes I read that 
article where MS says that HTML5 is the 'future of the internet.'  They said 
nothing about removing Flash support from Microsoft Windows in that article.  
Steve Jobs IS going to remove Flash from all Apple products everywhere -- 
THAT'S my problem with this!)


 
 If you want to develop for the iP*, then learn objective C or use 
 HTML5/Javascript. If you don't then don't. Again, it's a simple choice you 
 can make.

It's NOT a simple choice -- learning a whole other programming language is not 
a simple task.  Before old Steve-o came out against Flash, I could write one 
program that would work on Windows, Linux, and Mac.  Now Mac is gone from that 
equation -- thanks to some facist prick who thinks he knows everything that 
everyone else should do.

 
 Technologies change, sometimes their fortunes rise and sometimes they fall. 
 Flash has been the undisputed winner in the RIA wars up till now. Jobs is 
 betting the future of the iP* platform on HTML5. Maybe he's wrong about it, 
 but maybe he isn't. Time will tell.

Yes, technologies do change -- but it should be the free market that determines 
which technologies survive and which don't, not some ivory-tower egghead who 
determines by fiat what's best for everyone.  THAT'S why I called Steve Jobs a 
bastard.  Perhaps I should've said elitist bastard to make it clearer.

I truly DESPISE it when ONE person has the power to mess up things in my life.  
If everyone decided ON THEIR OWN to stop using Adobe Flash, that would be a 
completely different story -- the majority would have spoken, and I could more 
easily accept the outcome.  But Jobs is simply deciding that he knows best, and 
we're going to all follow him because he's so damn smart.  THAT is not the free 
market!

Figured this one out myself...  Turns out it had nothing to do with the theme, 
and everything to do with the fact that my data-grid was too wide to see the 
scroll bar.  As long as the Datagrid's verticalScrollPolicy is set to on or 
auto the vertical sroll bar will appear, it would seem...  

I just thought with all the scrolling changes that came about in Flex 4, maybe 
something got messed up.  But it was just me.  :-)

[flexcoders] Is it a ValueObject, or is it a String.

[Laurence]

I have a function (not written by me) that's returning either a String or a 
ValueObject, depending on whether or not it finds a match in an ArrayCollection 
of ValueObjects.  If it finds a match, it returns the ValueObject that matches 
the search string.  If it doesn't find a match, it returns the search-string 
itself.

So, here's my question -- how do I know if what's being returned is a String or 
a ValueObject?

I need something like the following:
   if returnedItem isString {
  //do stuff needed for when match isn't found
   } else {
  //do stuff needed for when match is found
   }

But I can't figure out how to word that 'if' statement -- how do you ask it if 
it is a String or a ValueObject, without knowing in advance what it's going to 
be?

Thanks,

Mableton, Georgia, USA

[flexcoders] Re: Is it a ValueObject, or is it a String.

I could've sworn I tried that, and it didn't work...

I did find something that worked, even though it's a bit of a hack...

if (String(returnedItem) == [object Object]) {
   //I know it's a VO and not a String
}

So that works...  I'll give your suggestion a try and see if that works -- 
although I think I tried it already.

Thanks for the suggestion,

[flexcoders] FocusOut event fires over and over...

[Laurence]

I want a pop-up window to appear when someone tabs out of a particular 
TextInput in my app.  So I simply set its FocusOut event equal to the function 
that makes the pop-up window appear...  Sounds simple enough, right?

But the FocusOut event keeps occurring over and over...  I type something into 
the TextInput then hit Tab.  The pop-up window pops up the way it's supposed 
to.  I select something in the pop-up window (or close it without selecting 
anything) and it pops right back up.  It's like my TextInput is re-gaining 
focus and then losing it again (which makes the window pop-up, again, forcing 
me to select something or close the window, which makes it happen again, etc.,

So how do I prevent this from happening?  Why is FocusOut occurring over and 
over and over like that?  I've tried, in my FocusOut handler, setting the focus 
onto another TextInput before calling the pop-up window, but that does no good 
-- same exact results.

This is incredibly frustrating!  Anyone have any ideas?

[flexcoders] Re: From your own experience how long does it take to learn AS3?

[Laurence]

It's also important to get your information from more than one source.  I used 
three different books, Lynda.com, and Adobe's Flex-in-a-week online videos 
(plus this forum, and dozens of Flex Blogs that I've found through Google 
searches).  Each one of them has their strengths and weaknesses -- the way that 
one of them explains a particular concept might just click better with your 
mind than another way.  So definitely don't limit yourself to only one source 
of training.

Indeed, like another poster has said, four weeks is nowhere near enough time to 
master this.  I've been doing Flex programming for over 18 months now, and I 
still have to refer to the documentation constantly (there's just SO much 
syntax, I don't think I'll ever have it all memorized completely).  Plus, I'm 
still learning new stuff every single day!  Even after 18 months!  This forum 
has been INVALUABLE to me in that regard.

And I have had many years of programming experience -- at one time or another 
I've written small- to medium-sized projects in maybe a half-dozen different 
languages, going all the way back to the 1980s.  With no programming experience 
at all, you should allow yourself even more time than average to learn this 
stuff.  You'll need to have lots of patience with yourself -- Rome wasn't built 
in a day, you know.

So definitely continue your lessons on Lynda.com.  Maybe buy a couple of books 
on the subject too, and definitely check out the Adobe Flex-in-a-Week free 
online video courses at Adobe.com.  (Of course, don't go through all that 
training material at the same time -- pick one and complete it before you start 
another.)  And, definitely keep this forum bookmarked on your computer -- it's 
a fantastic place to ask questions when you just can't figure it out on your 
own.  (Personally, I've found that going through the process of explaining my 
problem to others has often resulted in my finding the solution on my own -- it 
forces you to see your problem through the eyes of a potential responder, which 
can often lead to a eureka! moment while you're writing out your question.)

Best of luck to you!  A year from now, you'll look back on this and say to 
yourself Wow!  I've really learned a LOT that I didn't know back then.  It's 
a great feeling.

[flexcoders] Re: FocusOut event fires over and over...

[Laurence]

That doesn't seem to work either.  Focus keeps returning to the original 
TextInput for some reason...  I've even tried manually setting the focus to the 
next TextInput immediately after removing the FocusOut event listener on the 
first TextInput, before calling the pop-up window -- still doesn't work right; 
focus keeps going back to the first TextInput when the pop-up window closes.

Now, if I click somewhere else on the screen -- in other words, I don't click 
or tab into the next TextInput -- the window pops up just the one time...  I do 
not have any FocusIn or FocusOut parameters set in that second TextInput, so I 
don't know why clicking or tabbing into that second TextInput would cause the 
problem...

Anything else I should try?  This is just ridiculous -- it *should* work, but 
for some reason focus keeps getting sent back to the first TextInput.

I'm running Flex Builder 3.5a, and Flash Player 10,0,42,34.

Thanks,
L

[flexcoders] Re: What book in Flex would you guys recommend for a newbie ?

[Laurence]

I learned a lot from Adobe Flex 3: Training From The Source.  It takes you 
through an entire project, from start to finish.  They also have their own 
web-page and a discussion group as well.  Very, very helpful.

The book:
http://www.amazon.com/Adobe-Flex-3-Training-Source/dp/0321529189/ref=sr_1_1?ie=UTF8s=booksqid=1269025874sr=8-1

The web-site and discussion group:
http://www.flexgrocer.com/flex3.htm


Another good book is Flex 3 Cookbook.  It lists specific examples to solve 
specific questions you might have while working on a project.  It's not the 
book you want to start with, but it's a great reference to have when you've 
actually started working on your own projects.
http://www.amazon.com/Flex-Cookbook-Code-Recipes-Developers-Developer/dp/0596529856/ref=sr_1_1?ie=UTF8s=booksqid=1269026139sr=1-1

 As to the question of which books, I would say you would learn a lot from

 If you are still trying to learn AS3 then Essential ActionScript 3.0 is a

[flexcoders] Re: Automatically update ValueObjects...

[Laurence]

Tracy:  It does appear that using a relative path will not work...  At least 
not in the .CFC files...  (It does appear to work if I specify the 
relative-path in the Flex .AS component, and the full-path in the .CFC files, 
however...)  So apparently CF is looking for the path relative to the web-root, 
not to the .SWF's path...  If anyone knows how to change this behavior, I'd be 
very happy to hear it.

Valdhor: I need a separate working folder so that when I'm making changes, 
people can still use the app (in the live folder) for testing purposes 
without receiving silly errors that will pop up from time-to-time because I'm 
in the middle of editing something...  It's caused confusion before, and I'm 
simply trying to make it so the testers see as few errors as possible...  Of 
course, we have a completely separate server for our actual web-site, so it 
doesn't affect end-users...  But on the test-server, this issue has cropped up 
more than once, so I keep a separate working-folder and live-folder on the 
development server.

 Is there any specific reason you need a Working Folder? If this is new 
 code, don't you need new ValueObjects? If this is existing code and you need 
 to add new properties to a ValueObject, (I don't know if ColdFusion does, but 
 PHP does) you can subclass the existing ValueObject and add properties to the 
 new class. Either way, there is a new ValueObject class that will not affect 
 existing code.

[flexcoders] HTTPService not returning ArrayCollection...

[Laurence]

I'm trying to read data from an XML file, and put that data into an 
ArrayCollection.

This works great when I have more than one object in the XML file.  But when 
there's only one object in there, my HTTPService RPC returns it as an Object 
instead of an ArrayCollection of Objects.

So when I assign the event.result to my ArrayCollection I get a Cannot Convert 
to ArrayCollection error message...

Let me give an example:

MyXMLFile.xml:
people
   person
  firstNameJoe/firstName
  lastNameSmith/lastName
   /person
/people

If I have more than one person/person pair in my XML file, then they get 
returned as an ArrayCollection in event.result.people.person.  But with only 
one person/person pair in my XML file, event.result.people.person is an 
ObjectProxy -- which can't be converted to an ArrayCollection, apparently.

If event.result.people had a length property, I could just loop over it for 
{length} number of times and addItem() each person to my ArrayCollection -- 
but I see no length property on the event.result...  So how do I get this to 
work?  I won't know in advance how many person/person pairs are in the XML 
file, so I can't make any assumptions about the length...  Could be 1, could be 
100...

Is there a way to programmatically tell whether or not 
event.result.people.person is an ArrayCollection or an ObjectProxy?  If I could 
tell what it was, then I could use that information to let the program decide 
how to deal with it...

At 11:24 PM 3/2/2010, you wrote:


First, let me say that I have been roundly criticized for taking the 
approach of NOT using VOs.

Second, I use .NET  FluorineFX.

Yes, well, unfortunately it's way too late in this project to change 
our back-end.  It's gonna be CF9...  Period...  My bosses would 
*kill* me if I went to them now and said Hey, you know all that 
money we spent on CF?  Well, it was a complete waste.  Yeah -- that 
won't go over well...  Besides, they're already using CF on their 
production servers, and they're quite familiar with it.  It's not 
going to change...  .NET and Flourine are out...  Sorry...

So there has to be a way to do this with CF9.  I just haven't found 
it yet...  I'm still hoping to get a response here with regards to that...


If one were clever, using the approach above, one could create a 
Flex app that requests a table structure from the DB, and builds a 
data entry screen on the fly. You may want a schema table that 
contains data validation type info that would be read in conjunction 
with the table structure to allow edits to be performed by flex.

I have no clue how to do that...  I don't know what a schema table 
is...  I have heard of the term schema, but that's pretty much as 
far as my knowledge goes...  How do you create a schema table?  And 
how can I get CF9 to deal with it?

I do like the idea of building the data-entry screen on-the-fly, 
though -- that's probably what we're going to have to do...  I've 
actually already done that with one part of the program that deals 
with a variable number of fields that are all the same general 
type...  I guess I'll just have to migrate that to the rest of the 
program, to deal with these dynamic VOs.  (That is, if someone will 
ever tell me exactly how to create one...)


By the way, my main reason for resisting the VO structure, is I 
thought that keeping multiple copies of the VO in sync would be a 
PITA. Anytime you modified a table you need to modify at least two 
VOs, and potentially recompile middle tier and presentation layer programs.

Well, that does seem to be exactly the problem I'm running into 
here...  And I've still not heard anything from anyone about creating 
dynamic VOs.  I've read a couple of things about creating bindable 
dynamic objects, but I just can't figure out how to change that 
into a VO that gets passed back and forth between Flex and CF9.  If I 
could figure that part out, then this might work...  So, does anyone 
know how to create such an animal?

Alternatively, there was a suggestion earlier that I use an 
associative array within my VO to grab the changed fields.  I said 
that I'd never been able to get CF to return such an array, but I got 
no response on that...  Can anyone tell me how to get CF9 to return 
an associative array within a VO?  In case there's just no other way 
to do it...

This MUST be a common problem here...  Databases DO change all the 
time.  You can't tell me that Adobe hasn't created a secure way to 
deal with this...  Someone out there must know how to do what I'm 
trying to do here...  At this point, I'm willing to pay for the 
answer.  I've got to figure this out. And soon!

Except he's implementing it with LINQ and .NET 3.5   Anyone know how

[flexcoders] Dynamically create a Value Object...

[Laurence]

The program that I'm working on is for a company that does registrations for 
conventions and trade-shows.  Different clients want different information 
stored for each show.  Most of the information is the same from show-to-show, 
but every show has certain customizations that need to be done.

The way they're doing it now is by going into the source code of their program 
and modifying it that way.  We could do the same thing with our Flex app, but 
I'm trying like heck to avoid that...

The problem I'm running into is the Flex Value Objects -- they pretty much have 
to be compiled into the .SWF file, which means we're stuck modifying 
source-code and re-compiling for each individual show.  Not the solution we 
want.

Is there a way to dynamically create and/or modify Value Objects so they can be 
changed without re-compiling the .SWF file?  So that if a particular client 
wants stuff tracked that a different client doesn't want tracked, we don't have 
to create a generic version of our database that has all these extra fields in 
it, which most clients don't need?

As it stands right now, the Value Objects force us to make every database for 
every show exactly the same -- unless we modify the Value Objects for each 
individual show and re-compile a separate .SWF file for that show...  If there 
were a way to write, say, an .XML file that the program could read and modify 
itself accordingly for each show, that would be brilliant.  Is there a way to 
do that?

Thanks,

[flexcoders] Re: Dynamically create a Value Object...

[Laurence]

I should also mention we're using CF9 on the back-end.  So the VOs have to be 
defined in .CFC files as well.  So if anyone can tell me how to do dynamic VOs 
in both CF9 and Flex, that'd be wonderful.

Alternatively, if there's a way to transfer data between Flex and CF9 that 
doesn't involve VOs (but is still strongly structured and typed, like VOs are), 
then perhaps we need to do it that way?  I'm extremely confused here...  I've 
written this program from the beginning with statically-defined VOs, and now I 
discover that that's just not going to work.

So if anyone can point me in the right direction to help me learn what my 
alternatives to statically-defined VOs are, I'd really appreciate it.  I have 
found a couple of blog posts about bindable dynamic value objects, but only 
how to create them in Flex -- not how to export the data in them from Flex to 
CF9.  And the posts are pretty darn confusing, anyway...  Heck, at this point 
I'd be willing to PAY someone to teach me how to do this, one-on-one.  I really 
need someone who's an expert in both Flex 3.5a and ColdFusion 9.

Thanks,

[flexcoders] Re: Dynamically create a Value Object...

[Laurence]

We're using an SQL database with a ColdFusion intermediary between the Flex 
app and the database...  I've used XML files to configure a couple of the 
components -- give the user the option to change the layout of a component, for 
example, by modifying the contents of a config.xml file, that sort of thing...  
But I don't see us replacing our database with a bunch of XML files...  (Or 
maybe I completely misunderstood your reply, which is quite possible...)

I was hoping that there might be a way to get the program to modify its VOs by 
reading from an XML file what fields I want the VO to store...  But honestly, I 
don't care where that info is stored...  I just need to figure out how to 
dynamically modify a VO (and have ColdFusion realize that the VO has been 
changed by the Flex app) so I can deal with databases that have had fields 
added or changed without having to re-compile the entire program every time...  
And then, of course, how to reference these dynamically-modified VOs in my 
program.

Thanks,

[flexcoders] Re: Dynamically create a Value Object...

[Laurence]

Thanks for the suggestion...  I may be able to make that work...

If I understand you correctly, I'd need to return an array-within-an-array kind 
of thing...  My normal array of VOs, with one property of each VO being an 
array itself...  Sounds easy enough...

But I've tried before to get CF to do that (for a different problem), and 
failed...  Does anyone know how to get CF to return an array-within-an-array 
kind of structure?  I kept getting weird errors the last time I tried something 
like that - it kept acting like I was trying to create a two-dimensional array, 
when I only wanted a 1-dimensional array nested within another 1-dimensional 
array...  So obviously I was doing something wrong there...

Any suggestions are appreciated - thanks,
L.

 You could probably try having a base VO for all the properties that you know

 a Dictionary or a generic object used as an associative array to handle all

 and when it comes to extra properties, throw them in that one extra VO
 property.  You'd have to have some kind of parsing method on both ends but
 I'd think this would work without too much trouble.

[flexcoders] Re: Security issues SOLVED. (Mostly...)

[Laurence]

Ok, then...  Fantastic.  I am using AMF to communicate with the CFC's, and I'm 
using the SecureColdFusion channel I created to transfer the secure stuff, and 
the regular ColdFusion channel to transfer the non-secure stuff...  So even if 
I serve the .SWF over HTTPS, nothing will change (except I won't need to set 
'secure=false' in my crossdomain.xml file.)  Perfect.

So far, the only major differences I've noticed between CF8 and CF9 are the 
configurations of the channels themselves.  I found a comparison in this 
article: 
http://help.adobe.com/en_US/ColdFusion/9.0/Developing/WS5B9C73A8-5FA2-4a54-B0C6-CECA2E20052D.html

That, and the fact that my un-patched CF 8.01 server didn't enforce the 
public vs. remote policies on the functions in my .CFC's.  I've checked all 
my CFC functions to ensure that they have 'access=remote' set in the 
cffunction declaration.  Other than that, I've made no changes to my .CFCs, 
and they work fine with CF9.

But I've only been running CF9 for about a week or so?  I'm sure I'll notice 
other differences as time goes on.  But, so far, the transition to CF9 really 
hasn't been all THAT bad.  Just gotta make sure you specify CF9 when you're 
asking for advice -- that was my earlier mistake, assuming CF8 and CF9 were 
more similar than they actually are.

Best of luck in your transition.  Hope my experience helps you to avoid a 
couple of the pitfalls I fell into.  :-)

 It depends on how you are communicating with the CFC.
 
 If you are using the remoting protocols, then how those channels are

 test) https channels under an http web server. If you want secure data 
 transmission under AMF then you need to create and use a secure channel.  
 
 If you are using other means (wsdl, URL, parameters, etc.) to move data back 
 and forth, then the web server protocol comes into play.
 
 It would be nice for someone from Adobe to comment on this, especially with 
 some sort of overview of the differences between CF8 and CF9.  I'm going to 
 have to move soon to CF9 and you've already found one difference in the 
 services-conf.xml file (the endpoints) that I'm going to have to deal with.

[flexcoders] Re: .CFC cannot be accessed remotely...

[Laurence]

I'm guessing you're right.  I was running CF 8.01 (not ever patched, to my 
knowledge) on the old server, and CF9 on the new one.  So that explains the 
lack of enforcement of public vs. remote on the old server.

Where do I go to keep up with the patches for CF9?  Is there a single page 
somewhere that lists all the patches that have been released for CF9?  I'd like 
to do a better job of keeping this server up-to-date.

Thanks,
L.

[flexcoders] Re: SQL Question

[Laurence]

First off, I would suggest making your query much simpler, just to diagnose the 
problem.  Then add complexity to it and see if/when it goes wrong...

Start with (for example):
SELECT roomDisplay, roomID, ageGroup, accountType
FROM chatrooms
WHERE
cfqueryparam value=#arguments.accountType# 
 cfsqltype=cf_sql_varchar / IN (accountType)
AND cfqueryparam value=#arguments.ageGroup# 
 cfsqltype=cf_sql_integer / IN (ageGroups)

See what that returns for you...  Then start adding your Concat statements one 
at a time and see what changes.  It may not be following the same logic you are 
in your head, and this will force you to see it one step at a time, so you can 
figure out why it's doing what it's doing...

Best of luck,

[flexcoders] Re: Still getting Security Sandbox violations...

[Laurence]

Well, the lesson learned here is -- trust that the services-config.xml file 
that came with your CF installation is probably properly formatted.  Don't make 
changes unless you know precisely what you're doing.  :-)

In all seriousness, though, don't go copying everything from your old 
installation to your new one.  You will overwrite files that are important.  
You have to manually go through each file and ensure that EXACTLY the same 
stuff belongs in there on the new CF as did belong there on the old CF.  It's 
painstakingly slow, unfortunately...

[flexcoders] Security issues SOLVED. (Mostly...)

[Laurence]

So, here's my crossdomain.xml in its final form:

cross-domain-policy
site-control permitted-cross-domain-policies=master-only /

allow-http-request-headers-from domain=www.mydomain.com headers=* 
secure=false/
allow-access-from domain=www.mydomain.com secure=false /

/cross-domain-policy

This allows all the stuff on the SecureColdFusion channel I created to work 
just fine, as long as I access the site from mydomain.com and not from 
localhost or myserver01 (its NetBIOS name).

Even if I put allow-access-from domain=localhost/ (or 
domain=myserver01/) in there, it still won't allow access from localhost (or 
myserver01), because the security certificate is issued to mydomain.com -- the 
names don't match, so the browser/Flash/CF rejects it.  (I don't know exactly 
which one is rejecting it, but somewhere along the line it's being rejected 
because of the name-mismatch.)

The only way that I can see to change that behavior is to create two more 
virtual websites that point to the same location, and give each of those 
virtual sites their own certificate (one assigned to myserver01 and one 
assigned to localhost.  Otherwise, I can't access the app on my local server 
if the Internet goes down.  Yuck.  (If anyone knows a better way, I'm all ears.)

The one thing that still bothers me about this setup is the 'secure=false' 
tags.  I cannot get a straight answer as to exactly what this does to my 
security.  It enables http .SWFs to access https data, sure.  But does that 
mean it's disabling all https when it does that?  Or does it mean that it is 
secure during transit over the Internet, but not when it's being held in the 
Flex app?  Or does it mean something entirely different?  There is no site that 
has a direct answer to this -- they all just say it's not recommended due to 
security issues, or something along those lines.  But they don't specify WHAT 
security issues there are.  I need to know -- I can't serve my entire app over 
an https connection because it'll be too slow, but I must have secure access to 
some of the data...

So if anyone can answer the 'secure=false' question specifically, I would be 
very grateful.

Thanks,
L.

[flexcoders] .CFC cannot be accessed remotely...

[Laurence]

I've reinstalled everything on my server, including FlexBuilder and 
ColdFusion...

Now, when I run my app from within FlexBuilder, I get the following error 
message:
The method 'updateLoginInfo' in component 
C:\Inetpub\wwwroot\QMS\cfcs\dao\LoginDAO.cfc cannot be accessed remotely.

What does that mean?  It accesses the .CFC file when it reads the login info, 
but won't access it when it updates (writes) login info?  I really don't get 
that...

One note: I did have a problem importing the project into FlexBuilder.  It kept 
looking for a file called {CFROOT_FLEX}/wwwroot/WEB-INF/flex/libs/fds.swc but 
that file (and the entire folder, for that matter) isn't on this computer 
anymore...  Is that causing the remote-access problem?  If so, where/how do I 
get my CF web-inf/flex/libs stuff back?  I've installed CF9, and I was 
running CF8 before, so is there something in FB3 that I have to change for it 
to realize I'm now using CF9?  Should I have installed FB3 before I installed 
CF9?

Thanks for any help you can give me.

[flexcoders] Still getting Security Sandbox violations...

[Laurence]

Here's my crossdomain.xml file:
?xml version=1.0?
!DOCTYPE cross-domain-policy SYSTEM 
http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd;
cross-domain-policy
allow-access-from domain=*/
/cross-domain-policy

So how is it, with EVERY domain allowed, I'm getting the same old Connection 
to https://mydomain.com/flex2gateway/secureamf halted - not permitted from 
http://mydomain.com/myappfolder/myapp.swf;?

Now, I've read some of the information on policy files...  They mentioned 
something about setting secure=false in the allow-access-from line if 
you're accessing https: data from an SWF file that was loaded with the http: 
protocol.

I have two questions about that:
1) If I set secure=false won't that negate the whole point of using a secure 
channel in the first place?  I mean, why have a secure channel if you're going 
to set secure=false?!  (Further, if I put my actual domain in there instead 
of *, setting secure=false still gives me the Security Sandbox violation 
anyway... So what's the point, really?  secure=false doesn't seem to be what 
I want here.)

2) If I go ahead and set secure=false and leave the domain=*, instead of 
getting the Security Sandbox violation, I'm getting a Channel.Connect.Failed 
error NetConnection.Call.Failed: HTTP: Status 404: url: 
'https://mydomain.com/flex2gateway/secureamf'  So HTTP 404, that's 
file-not-found...  What file is it not finding?

How hard is it to understand?  I purchased a copy of ColdFusion 8 about two 
years ago.  We've been running it this entire time.  I had been running the 
32-bit version of CF8, and recently discovered that enabling 32-bit apps on our 
64-bit version of IIS is what was causing all the security problems (or at 
least it appeared to be the case, because when I formatted and re-installed 
everything, the IIS server started doing its weird stuff again immediately 
after I installed the 32-bit Reporting Services for MS SQL Server 2005.)

Anyway -- long story short -- I need to install the 64-bit version of CF8.  But 
my license key won't work with it.  It only works with the 32-bit version of 
CF8.  I can go all the way through the install process on the 32-bit version of 
CF8.  But on the 64-bit version, it chokes when I enter the key.  The very same 
key that WORKS in the 32-bit version.

So all I need is a key that will work with the 64-bit version of CF8.  I've 
been on the phone and on the live-chat with Adobe tech-support for HOURS!!!  
And they just don't get it!!  I just need a damn key that will work.  I've 
given them my existing key, and they tell me that it is a valid key.  So why 
won't it work with the 64-bit version of CF8?!!!  It's a simple request -- give 
me a key that will work with CF8 64-bit!  Damn!

[flexcoders] Re: Any Adobe folks on here?

[Laurence]

With the help of an Adobe person who e-mailed me privately, we have figured out 
what is wrong...  Apparently 64-bit ColdFusion 8 is only available for the 
Enterprise Edition.  My key only covers the Standard Edition.  So at least we 
know why the key wasn't working.  Why the customer-service and/or tech-support 
people couldn't tell me that is just beyond me...  Would've save a LOT of time 
if they'd just known that fact from the beginning.

Anyway -- now my problem is this:  How do I install 32-bit CF8 on a 64-bit IIS 
without killing CertSrv?  Heck, I guess I should join a CF group, eh?  LOL  I 
think I'll do that right now.  But if there are any folks in the Flex group 
here who've dealt with this problem, please feel free to e-mail me.

Thanks,

[flexcoders] Re: Any Adobe folks on here?

[Laurence]

Well, I figured this one out, too...  Apparently it's not possible to install 
32-bit *anything* on 64-bit IIS, unless you put IIS into 32-bit mode by 
running the following script:
C:\Inetpub\AdminScripts\cscript.exe adsutil.vbs set 
W3SVC/AppPools/enable32BitAppOnWin64 true

And it's that script that kills CertSrv on 64-bit IIS.  This flag must be set 
to false in order for CertSrv to work on IIS.

So to solve the problem, I talked my boss into buying 64-bit ColdFusion 9 
Standard Edition Upgrade.  Hell of a solution, eh?  LOL

Anyway -- thanks to the guy from Adobe who e-mailed me off-list (and especially 
thanks to the group-member here who forwarded my e-mail to him!!)  Without your 
help, I'd never have figured this out.  (I'm not naming names, in case they

  How hard is it to understand?  I purchased a copy of ColdFusion 8 about two 
  years ago.  We've been running it this entire time.  I had been running the 
  32-bit version of CF8, and recently discovered that enabling 32-bit apps on 
  our 64-bit version of IIS is what was causing all the security problems (or 
  at least it appeared to be the case, because when I formatted and 
  re-installed everything, the IIS server started doing its weird stuff again 
  immediately after I installed the 32-bit Reporting Services for MS SQL 
  Server 2005.)
  
  Anyway -- long story short -- I need to install the 64-bit version of CF8.  
  But my license key won't work with it.  It only works with the 32-bit 
  version of CF8.  I can go all the way through the install process on the 
  32-bit version of CF8.  But on the 64-bit version, it chokes when I enter 
  the key.  The very same key that WORKS in the 32-bit version.
  
  So all I need is a key that will work with the 64-bit version of CF8.  I've 
  been on the phone and on the live-chat with Adobe tech-support for HOURS!!! 
   And they just don't get it!!  I just need a damn key that will work.  I've 
  given them my existing key, and they tell me that it is a valid key.  So 
  why won't it work with the 64-bit version of CF8?!!!  It's a simple request 
  -- give me a key that will work with CF8 64-bit!  Damn!
 

[flexcoders] FlexBuilder 3 and ColdFusion 9 Extensions...

Anyone know where I can download the ColdFusion 9 Extensions for  Eclipse?  I 
can find only the CF8 Extensions...  I'd really like to install the CF9 
Extensions, assuming they exist...

Thanks,

[flexcoders] Re: Any Adobe folks on here?

That is exactly correct.  You can have either a 64-bit app pool or a 32-bit app 
pool running on any given site.  But not both at the same time on the same site.

[flexcoders] I hate dealing with security issues...

[Laurence]

Ok.  I finally figured out how to create my own security certificate on my 
Windows 2003 server, using Certificate Services.  I can access my server using 
https:// right now -- the browser gives me an error because it's not a trusted 
cert, of course, but https:// does work if I ignore the not trusted message...

So, I'm trying to secure a ColdFusion 8 data-channel on my intranet.  I've 
edited the services-config.xml file to give me a cf-amf-secure channel, and I'm 
directing one of my remote objects to my new SecureColdFusion destination...

Obviously the CF part appears to be working -- because it IS attempting to 
access https://localhost/flex2gateway/cfamfsecure.  But every time it does, I 
get a cross-domain policy error.  If I run the program in Debug mode, I 
actually get a failed to load https://localhost/crossdomain.xml; error message 
immediately before I get the general security sandbox error.

What I think is happening is that Flex is trying to load the crossdomain.xml 
file through https:// not http:// and the untrusted security certificate is 
preventing the crossdomain.xml file from being loaded.  I did add a 
'Security.loadPolicyFile(http://localhost/crossdomain.xml;);' command to my 
program, and that didn't change anything.  It still gives me the failed to 
load error.  Did I mention I hate security issues?

Anyway -- I think the trick is to somehow make Flex trust my self-created cert. 
 If I can do that, then it should be able to load crossdomain.xml from the 
https.  Can anyone help me get Flex to trust my self-created certificate?

Thanks,

[flexcoders] Re: I hate dealing with security issues...

[Laurence]

Ok...  I installed the Cert in IE.  It shows up in the Trusted Root Authority 
tab in Internet Options.

Now, I'm getting the following error:  (I've replaced my actual domain with 
{myDomain} in the following example)
Warning: Domain {myDomain} does not specify a meta-policy.  Applying default 
meta-policy 'master-only'.  This configuration is deprecated.  See

file permissions.

*** Security Sandbox Violation ***

permitted from http://{myDomain}/QMS/QMS.swf


So is the lack of a meta-policy now causing my problem?  (I did read that 
website it links to -- totally didn't understand a thing...)  I'm no longer 
getting the error loading policy file message, so I assume that means it's 
loading.  And {myDomain} is listed in the policy, so I really don't understand 
why this isn't working...  It should.

Did I mention I despise security problems?

Thanks for any help you can give me.

[flexcoders] Re: I hate dealing with security issues...

[Laurence]

Ok - I've already posted a reply to this once, but that was an hour ago and it 
still hasn't showed up in the messages list.  So my apologies in advance if 
this winds up being a double-post.

Anyway -- I followed the intstructions for importing my cert into IE.  I can 
now browse to https://{myDomain} with no cert-errors.  But Flex still isn't 
dealing with it correctly.  (Obviously, I've replaced my real domain with 
{myDomain} in this example.)

I get the following error:
Warning: Domain {myDomain} does not specify a meta-policy.  Applying default

So I'm no longer getting the error loading crossdomain.xml problem that I had 
before...  But now this new error about a meta-policy?  I went to the web-site 
it told me to go to, but I didn't understand a damn thing.  Is my lack of a 
meta-policy the problem here?

So someone please give me a clearer understanding of what a meta-policy is, and 
how to create one?  (If that is, indeed, my problem...  It's still telling me 
there's a lack of policy file permissions which is completely wrong -- 
{myDomain} is in there...)

Thanks for the help.  I truly despise security issues...  Ugh...

[flexcoders] Another security question...

[Laurence MacNeill]

With all this talk about security, I figured now was the time to get 
SSL running on my Windows Server 2003 computer...

I'm sure that others here have dealt with this before -- so although 
it's not specifically a Flex topic, I'd imagine it'd be of interest 
to enough members that my posting this here won't be totally 
offensive to everyone.

Anyway -- I installed Certificate Services from the Add/Remove 
Programs on the Control Panel.  That seems to have completed successfully.

I've completed the steps in IIS to 'request a certificate' -- saved 
the request to a file on my desktop.

Now, the next step is supposed to be going to 
'http://localhost/CertSrv' and creating a new certificate from my 
.txt file that contains the saved request.  But when I browse to that 
page, it says 404 Page Not Found.

I've checked all the usual suspects -- IIS shows that CertSrv is a 
valid page, all the proper .ASP files are in there, ASP services are 
enabled on my IIS server, at a command prompt 'certutil -vroot' says 
all the virtual pages and directories are properly installed...   I'm 
just at a complete loss as to why my browser can't find the CertSrv 
page...  Heck -- I even re-booted the computer, just in case that was it.

Anyone dealt with this before?  Got any tips?

[flexcoders] Re: Flex Project Hosting

[Laurence]

If your host can send a .SWF file to the client's browser, you can run a simple 
Flex program. 

If you want the program to do anything useful, like storing data on the server, 
for example, the host needs to offer back-end support for ColdFusion, and some 
sort of SQL database.  There are many other back-ends that will work also 
(besides ColdFusion), but I'm not knowledgeable enough to list them all here... 
 Someone else, I'm sure, will have that info.

[flexcoders] Re: Limited Heap Space Problem

[Laurence]

Well, first of all, I'd try to find another way of allowing users to view your 
50 .PNG files, without embedding them in your code.  That'll free up a TON of 
memory.  (It's why Hard Drives were invented.  GRIN)  Maybe load them into 
memory from a folder, as they're needed, rather than embedding them all?

Through a little experimentation, I've found that you CAN increase the Xms and 
Xmx variables to 1024m, if your -XX:MaxPermSize is 512m or less.  (And 
obviously the -XX:PermSize must be equal to or less than -XX:MaxPermSize.)

Also, each thread you're running will use a stack -- if the stack size is too 
big, that will limit the number of threads you can run.  So maybe the default 
stack size is too large for your particular app?  Try adding an -Xss1204k to 
the .ini file and see if that changes anything...

Best of luck.

communicate with the server via SSL, or some other method whereby the 
credit-card numbers it sends to-and-from the server are encrypted.

Here's how it's structured currently:

   mx:method name=getPayments result=roGetPaymentsResultHandler(event) 
fault=roFaultHandler(event)/

fault=roFaultHandler(event)/
/mx:RemoteObject

there a way to encrypt just that one mx:RemoteObject?  If there is a way to 
secure just the one object, how is that done?

Re: [flexcoders] Re: Custom ItemRenderer still not working... [1 Attachment]

[Laurence MacNeill]

I fear I'm not explaining the problem properly.  So I'm attaching a 
screen-shot of what the problem is, exactly.

As you can see from the screen-shot, the selected combo-box is 
displaying a number -- the correct number ($275.00) -- in the main 
display area.  But in the combo-box's drop down, are two completely 
unrelated numbers ($315.00 and $325.00).  If you were to select, say 
$315.00, the displayed number would change to $255, and the next time 
you open that combo box, the drop-down would show the proper numbers 
($255.00 and $275.00).

I hope that helps to explain the problem, if there are some folks out 
there who aren't understanding it.

shows up in there, too...  At least, on my computer it does.  :-)

One thing I noticed, however, is that in Firefox the Flash-version 
shows up as 10,0,32,18 -- even after I visited the adobe.com site to 
update it to the newest 10,0,42,34 version...  Bug or deliberate?

Re: [flexcoders] Re: Custom ItemRenderer still not working...

[Laurence MacNeill]

I just installed the latest nightly-build for Flex 3.6 -- version 3.6.0.13443.

THAT FIXED THE PROBLEM!!!

Weird that 3.6.x would fix the problem, whereas 4.0.x didn't...

And I still don't know where to get that 3.5.0.13209 or later that 
Alex Hauri talked about...  Latest 3.5 build I can find is the 3.5a 
that I've already got...  If someone could show me where to get 
3.5.0.13209, I'd appreciate it.

So -- I guess the only question I have left is this:  Can I use 3.6 
in a production build, or is it too beta for that?  I'm reluctant 
to trust a nightly build to a production environment...

Thanks,
L.

Know an easy way to export my SQL data as something I can post here?  Something

the test-program can read?


 Your DataGrid is not editable, correct?  And your render is not set
 as an editor, right?

The data grid IS editable, and one of the columns has renderer-as-editor set.  
NOT the column that's giving me the trouble.  In fact all the columns have 
editable set to false, except one column -- again, NOT the one that's giving me 
trouble.


 I assume you have debugged this and have tested to see that the
 dataProvider is set when you set selectedItem?  Maybe there is a
 timing issue with the bound dataProvider. Loop over the items to
 make sure the item exists.  And make sure it matches the
 selectedIndex.  I'd probably suggest you do this any way and use
 selectedItem always.
 
 I would use a conditional, testing for the selectedItem, rather
 than blindly setting selectedIndex every time.

Not 100% certain what you mean here...  Check to see if the selectedItem isn't 
null?  The problem I'm having is not that the selectedItem changes (or appears 
to change) when you scroll.  It's solely in the drop-down.  The data that 
appears in the drop-down will change from time-to-time as you scroll -- but the 
selected value doesn't change ever, unless you change it manually.  And when 
you do change it manually, it shows the value it's supposed to show!  Then you 
re-open the drop-down and THAT show's the correct values, too!  That's what's 
so weird about this problem.


 Finally, I strongly suggest you move that work into
 commitProperties() The set data() function gets called much more
 often than you may realize.

I've never used the commitProperties() function...  What does it do?  And when 
does it get called?  Would that work 100% of the time?  Basically you're 
telling me to do super.data = value in the set data() function, then 
populate the drop-down and selectedItem stuff in the commitProperties() 
function?  Is that what you're saying?

I'll be working on writing a test-case -- the biggest part of it seems to be 
exporting my data.  I can't find a shortcut to doing that.  But if you can 
answer my above questions, then maybe I won't have to write the test-case?

Anyway, thanks a bunch!

Yeah, one should be good enough, I agree...  If you notice, however, that I set

when the database has been corrupted or accidentally changed, and none of the

[flexcoders] Re: Custom ItemRenderer still not working...

Well, I found a work-around...

I added the following code inside my ComboBox ItemRenderer:
override protected function focusInHandler(event:FocusEvent):void {
 listOfFees.refresh();
}

For some reason, with this in there, you have to double-click on the combo box 
to open it, but the drop-down shows the correct data 100% of the time.  Good 
enough for now.

Yeah, I figured as much.  I noticed that if I opened then closed then re-opened 
the drop-down, the data would sync itself properly.  Adding this refresh() 
statement was a way to force that to happen -- the user clicks on the combo 
box, the refresh happens (forcing the box closed), then the second click opens 
the drop-down with the proper data...  Total hack-job, but it works.

 
 I couldn't find your previous post to look at the code, but I still suspect
 recycling issues.  For a combo box, you have to do two actions on set data
 (actually  in commitProperties, of course).  You must re-assign to
 dataProvider, and you must set the selectedIndex (you can only use
 selectedItem if your items are simple strings or numbers).  Are you doing
 both of those things?

when I change the 'EventVO.as' such that course_fees is an ArrayCollection

a problem with my CF code (EventVO.cfc and EventDAO.cfc)?  How do you get CF to

not possible...

listOfFees an Array or ArrayCollection...

 Subject: [flexcoders] Trying to use an Array inside a VO.
 

 I have a Value Object called EventVO.  Inside this object, I want there to be 
 an Array, in addition to the various Strings and ints that are in there 
 already of course.
 
 My problem comes in the initialization function.  It currently looks 
 something like this:
 public function EventVO ( param1:String= , param2:int=0) {
 this.param1 = param1;
 this.param2 = param2;
 }
 
 Let's say I want to make param2 an Array instead.  I would think it should 
 look something like this:
 public function EventVO (param1:String= , param2:Array= []) {
 this.param1 = param1;
 this.param2 = param2;
 }
 
 But that gives me the following error:
 1047: Parameter initializer unknown or is not a compile-time constant.
 
 So how the heck do you initialize an Array inside a list of 
 function-parameters ?  This has been driving me CRAZY!!  I can't find the 
 answer anywhere.
 
 Your help would be greatly appreciated.  Thanks.

[flexcoders] Custom ItemRenderers and scrolling on a DataGrid...

[Laurence]

Ok, I know this question has been asked a thousand times (or more), but when I 
search for information on Item Renderers here, it just returns SO many results 
that I just can't find what I'm looking for...

How do you get a custom Item Renderer not to change its data when you scroll 
down a list on a DataGrid?  I just can't remember the trick to making it 
happen...

Here's the link to a site with an example of what I want to do: 
http://butterfliesandbugs.wordpress.com/2007/09/11/dynamic-itemrenderer-using-a-combobox/
  

If you take that above example, and set the DataGrid's rowCount = 3, then 
scroll it back and forth a few times, it corrupts the data in the ComboBoxes... 
 How would you fix that?

Of course, that doesn't work...  It simply creates a blank array that's

[flexcoders] Searching a DataGrid...

[Laurence MacNeill]

Hi,

I have a DataGrid that contains a long (sometimes VERY long) list of 
names -- anywhere from a couple hundred to over 5,000.  I need to be 
able to allow the user to search this list by typing a name (or 
part of a name) into a TextInput and clicking a button.

Implementing the TextInput and the Button are no problem of course, 
but how do I get the DataGrid to scroll down to the closest match in the list?

Thanks,

Being relatively new to Flex, I'm probably not qualified to answer

CF to be the more straightforward approach, albeit the more 
expensive one, when compared to JSP.

FlexBuilder just makes it so easy (especially with the CFEclipse 
add-on) to work with your CF server-side stuff at the same time 
you're coding in Flex.  And the CF-wizards that are included with 
FlexBuilder are so easy to use -- only a few clicks to create the CF 
VO to go with your Action-Script VO, with minimal changes needed in 
the wizard-generated CF code to make it work.

I just find woking with CF to be a ton easier than working with JSP, 
I guess is what I'm trying to say.  FlexBuilder was created by Adobe, 
so they're probably biased towards CF, which is probably why working 
with CF within FlexBuilder is easier out-of-the-box.  But it works well for me.

first time I use the FindAny() method, it works fine.  The second 
time I use it, it doesn't seem to find anything.  Do I have to reset 
the cursor before I can use it again?  Move it back to the beginning 
of the ArrayCollection so it will be able to find everything?  I 
would think that FindAny() would find any instance of the search 
object, no matter where it is in the collection, but maybe I'm wrong.

So, do I need to reset the cursor to use FindAny twice?  And, if so, 
how do I do that?

Thanks,
