[flexcoders] Question on extending components for Mobile Apps
Hello All, If I am to create custom components inside of Flash Builder for Mobile, does it always have to begin by extending the View Class? I'm not talking about custom controls, but Views that would contain a ton of custom controls (one being a Loader component). Up until now (for non-mobile apps), I've always started by extending the UIComponent Class since that is probably the most basic class to build upon. Thanks for any advice you can throw my way, Mike
Re: [flexcoders] Re: opening another Window in Flex for commenting on data entered in TextArea compon

[flexcoders] Re: Line Chart, I have a X value, how can I find the Y value?
I did something like this for EBay. I defined a hierarchy of Equation classes, including linear, nth order polynomials, power law. The base Equation class provided common functionality such as data initialization and solving for the unknown gien a variable. Applications could then be written that called the library function in real time, so a mouse could be tracked while live X and Y intercepts were displayed, etc. Sorry I can't offer the source code. Hopefully this gives you an idea of how you might proceed. Mike
[flexcoders] Re: Using modules and remote objects
I recently did something like this for Cisco. They needed a way for a sub-Application to invoke a method in another sub-Application, which might not be loaded. The solution was to derive the sub-Applications from a common base class and use the main Application as a broker. The broker listened to function invocation request events. Results of the method calls were made available by a custom event that was dispatched by the called method upon completion. Here is a clue to how to implement this type of mechanism: the SWFLoader that loads a sub-Application has a property called content, which is actually the sub-Application's FlexGlobals.topLevelApplication once the sub-Application loads. Confused? I created a UML sequence diagram, a static object model diagram and a text narrative to document how the mechanism worked. Anyone else attempting something similar is well advised to do the same. Mike

[flexcoders] Re: Web Services and ObjectProxy question for the Flex Gurus
Michael, The Flex SDK can do what you want, but the default behavior is for it to unwrap collections and enclosing types which only contain one item. This default was not a good idea, IMO. Have you tried setting Operation.forcePartArrays true? http://livedocs.adobe.com/flex/3/langref/mx/rpc/soap/Operation.html#forcePartArrays You will need to obtain the mx.rpc.soap.Operation from the WebService first. You can alter the default behavior by writing a custom deserializer (which is a non-trivial task, made more difficult by the ASDoc being turned off.) For more information about Flex WebService, see my slide show and YouTube video at http://www.slideshare.net/mslinn/using-flex-with-enterprise-web-services Mike I'm using Flex 4 and I set the returntype for the webservice to return an array of Cars - Cars[]. If the web service returns more than 1, it successfully deserialized the data and returns an array of Car objects. BUT, if only one is returned, it returns an ObjectProxy, obviously because it cannot convert it to an array.
[flexcoders] Problem with data displayed in Drop Down, versus actual underlying data
Hello All, I am banging my head on the wall with this issue - I have 1 dropdown control's dataProvider, tied to the remoting results of another dropdown's database query. You can keep selecting a different value from the primary dropdown, and the secondary dropdown updates the underlying dataset beautifully, BUT if you click the secondary dropdown to display the actual values, it still displays the list from the PREVIOUS database query. The interesting thing is, if you click an actual value from the dropdown, it selects the correct underlying value contained in the index position, although the displayed value is wrong (the value from the previous query). I am using Cairngorm for my framework - and have the model.returnedQuery tied to the secondary dropdown box - so whenever I kick off a command, the values automatically update, since the dataProvider is tied to the model. Do any of you, have any ideas as to what's causing this? Thanks in advance for all your help, Mike P.S. I am using Flash Builder 4 compiling in Flex 3.5 (this problem still existed when using Flex Builder too).

Re: [flexcoders] session variables
On the server you have code that tracks who is logged in. In Flex, when a user logs in, you end the first session when a second active session is started for that user. In Flex, ping the server every so often to check whether or not you need to kick the Flex user off due to this policy violation rule. Show a message like a second active logon has been detected, so you have been logged out. This isn't a trivial feature to implement. Maybe a first step would be to log more data so you know how common the problem is. It might turn out to be a minor issue that isn't worth dealing with, or an issue that can be handled differently, such as by reminding suspected violators of the rules via an E-mail. -Mike Chabot On Sat, Mar 13, 2010 at 2:32 PM, iloveyouwisconsin iloveyouwiscon...@yahoo.com wrote: I have a flex app that users pay to subscribe to my content.

Re: [SPAM] [flexcoders] Obtaining rendered text from a DataGrid
I have no control over the dataProvider at all. Performance is not an issue, because the data extraction only happens once, and it can be time-sliced it so the webapp does not appear to freeze. Passing through multiple event handlers, including EnterFrame would be perfectly acceptable. 3) Depth: Since you have no control over the renderers, you don't have any way of knowing whether they're composed of containers within containers, etc. True. The routine needs to deal with that. 4) Layout: Presumably, you want to have the text appear in the same order it appears in the columns, and then within the individual renderers. There's no guarantee that your iteration will go from top left to bottom right, so you'll have to record where the text was found and then arrange it in some way that tries to make sense (but may not, depending on what is going on in the renderers). Yes, doing this right will be a lot of work. 5) Random surprises from the renderer developers. If the renderer developer makes a reference to its parent, owner, or something else like that and you instantiate it in a way that doesn't involve a List of some sort, you may wind up with Null Pointer Exceptions. They may come up with other stuff that won't come up in your testing with reasonable renderers that you wrote, but it will be your fault when they do something stupid and YOUR logic errors out. Yep, that is true. In short, you have to work together with your other team members one way or another to make this work. There are no other team members. This is a library routine. I want this to be as general as possible, and am prepared to do what it takes to make it work properly. Why not just shortcut to the most performant method? Performance is not important, general utility is important. The library feature should just work, no excuses.
[SPAM] Re: [SPAM] [flexcoders] Obtaining rendered text from a DataGrid
Because this is an library for exporting to other formats I only need to instantiate one renderer at a time. Memory requirements should therefore be modest. I have implemented a mechanism to export the display lists of non-text item renderers. The tricky part is learning how to instantiate any type of renderer on demand. Hopefully constructive suggestions will be forthcoming soon.

And I still haven't figured out what you'd do for renderers that don't display any text. And I'm pretty sure I could write a renderer that you could never figure out which children have text. But given all that, then start copying code from DataGridBase.as. CreateColumnItemRenderer, setupItemRenderer and some calls to validateNow should get the renderer in its final state, and code in FocusManager, addFocusables walks children in the two known ways of figuring out your children. If you run into TextFields, pull their text or htmlText and if you run into TextLines Not sure what you'll do there.
[flexcoders] Obtaining rendered text from a DataGrid
I need extract the rendered text from all cells of a DataGrid, whether or not
they are all displayed. The following code dies because renderer is null:
public var dp:ArrayCollection = new ArrayCollection();
/** Obtain formatted text data from the DataGrid's dataProvider.
* Other data generated by item renderers such as images are ignored. */
protected function extractData(originalComponent:*):void {
var dg:DataGrid = DataGrid(originalComponent);
for (var col:int=0; coldg.columnCount; col++) {
var rowArray:Array = [];
for (var row:int=0; rowdg.rowCount; row++) {
var index:int = dg.indicesToIndex(row, col);
var renderer:IListItemRenderer = dg.createItemRenderer(index);
var value:* = renderer.data;
rowArray.push(value);
}
dp.addItem(rowArray);
}
}
Most of my posts to this group go unanswered. Hopefully this one won't suffer
the same fate! :)

Re: [SPAM] [flexcoders] Obtaining rendered text from a DataGrid
I need to post the displayed data to a server, complete with formatting. The dataProvider does not help much; I'd have to replicate the work that the datagrid does in determining the properties displayed by each column, and duplicate the job of the item renderers in order to extract the displayed property of each column. I see that itemRenderers can be created ad hoc, so it must be possible to shove data into them and obtain the displayed values. ... it is nice to get a response, and so quickly too :)
[flexcoders] Re: Obtaining rendered text from a DataGrid
I meant formatting, as in currency, decimals, thousands separators, etc. but I don't need stylesheet info like font size or face. Seems like your approach may be exactly what I need. indexToItemRenderer() returned null, but maybe I invoked it improperly. I suppose you mean Flex DataGrid Excel Export, $7. If that product includes source code, then it would be a worthwhile source of inspiration. Does the download include source?

I can only suggest a 'try'...did you try using the datagrid's indextoitemrenderer method instead of creating a new item renderer... I have seen something similar in the DataGrid to Excel component on Flexdownloads.com but there the exercise was limited to extracting data from datagrid using the label function of the datagrid or if no label function specified, just use the data displayed, without the formatting css.

Re: [SPAM] [flexcoders] Obtaining rendered text from a DataGrid
I must take the DataGrid as I find it. If no labelFunction is defined, that approach won't work; also each item in the dataProvider might be manifested in 0 or more columns. This approach probably won't be general enough. Thanks, Mike You should be able to do this by running the labelFunction on all items in the dataProvider. You'll need to change the method signature to allow for a null dataGridColumn, or pass in a dummy dataGridColumn. HTH; Amy
Re: [SPAM] [flexcoders] Obtaining rendered text from a DataGrid
Alex, Your code is very interesting, and quite instructive. Thank you. You said that your code handles labelFunction and dataField; however the asdoc for the itemToLabel() method reads: public function itemToLabel(data:Object):String Returns the string the renderer would display for the given data object based on the labelField and labelFunction properties. If the method cannot convert the parameter to a string, it returns a single space. ... no mention of dataField. Am I missing something? The goal is to export the text from any datagrid's displayed cells into a 2D array that is sent to a server. In the general case, one cannot assume anything about the dataProvider, or how the text in each DataGrid's cell is constructed. There are no constraints on the types of renderers that need to be supported. The export should handle any datagrid handed to it. This means that if item renderers are used, they need to be instantiated and the text values for each cell read out... and the export routine has to figure out how to do this without any clues beyond what it can discover from the dataGrid. Something to go 'hmm' about... Mike --- In flexcoders@yahoogroups.com, Alex Harui aha...@... wrote: I'm still not sure what your goal is and what things are under your control. I can have a renderer that displays content not found in the data provider, or one that shows colors and no text. A renderer can have multiple text widgets inside it and be mixed with other controls. Is there some constraint on what kinds of renderers you want to grab text from? Usually, you own the renderers. Are folks supplying renderers for you to use?
[flexcoders] Re: What's up Adobe?
It's too late, the damage is done, but I agree also FWIW. An Adobe VP told me about Flex being the open source branding, and Flash being the commercial product branding. There is no way that customers will figure that out. They have enough trouble understanding that developers are left-brained and designers are right-brained. One should not target a single brand at two classes of individuals who have different educations, different values, different world views, drive different cars and listen to different music. If you believe you know of a top-notch designer who is also a top-notch developer, your standards are too low. One cannot excel at both career paths - humans are too finite. Mike ... who tries to excel as a developer and has great respect for excellent designers âYes, I can see your point. I think the two of us are the only people who think that the Flex brand is weakened by the Flash moniker.â No, there are more of us... We just arenât as vocal!

[flexcoders] Using PlotSeries icon in a seperate control

[flexcoders] asdoc Error: Property is write-only.

[flexcoders] Re: Inserting Datagrid printscreen in PDF with AlivePDF
I gave up on AlivePDF. All it can do is provide fuzzy screen grabs; the width and height of the displayed UIComponent determines the printed output, which sucks. No pagination is possible. The Flex PrintGrid is also inadequate for reporting needs. Instead, I wrote a Java program that create PDFs from an application's data, using the iText library. This is the same library that Cold Fusion uses for creating PDFs. The Flex client sends the data that needs to be printed to a server using an HTTP POST, and my little Java program generates the PDF. The result is a crisp, paginated document. The data is sent as XML; the only tags I currently support are image / and table /, and just enough attributes to satisfy this client's needs. BTW, iText allows other PDFs and files to be merged, and the generated PDF could even contain a Flex app and data... but that is another story. Sorry I can't provide the source at this time, because it was paid for by my client. If they are willing to make the source available at another time, I'll publish it. It only took about 10 hours to write a POC, not a big deal. If another client wanted this, I could write a similar program easily enough. Mike
Re: [flexcoders] Flash Player Security Bug

[flexcoders] Swing Layout Manager Equivalent in Flex 3
I have built many GUIs with Swing and two of the Swing Layout Manager Options I found most useful were Flow and Border. I have a design goal where I am creating a component that has a Data Grid under a set of control icons. If the browser window shrinks to the point the control icons can no longer be shown without scrolling I would like them to flow down to the next row and the panel or canvas they are on be doubled in height to accommodate the wrap around row of icons. I tried FlowBox but that only works if i have it double high all the time and that defeats the purpose. I suppose I could run some code in the resize event handler and if the size drops below the width of the icons, I could then double the hieght and if it grows back to wide enough I could halve the hieght. But I am lazy and was hopping there was a Swing Layout Manager equivalent. -- View this message in context: http://www.nabble.com/Swing-Layout-Manager-Equivalent-in-Flex-3-tp24634003p24634003.html Sent from the FlexCoders mailing list archive at Nabble.com.

[flexcoders] Question about accessing Flex from Java
Hi, I have a question about accessing Flex from Java. Some context: I am writing automated JUnit integration tests that will call the remote objects in the Flex application that is under test. We also have Junit unit tests and will have automated Flex GUI tests ... but this question is specifically about the integration tests that I want to write in Java with JUnit to call the remote objects. I have a simple integration test that accesses the application: AMFConnection myamfConnection = new AMFConnection(); And I *think* it will be easy enough to call the remote objects. But first, I need to login or authenticate ...and I am puzzled. The Flex application under test uses ChannelSets ... and this is specifically where I am puzzled. I am having trouble figuring out how to login, authenticate, or otherwise create the ChannelSet from a Java client. So this is my question how to access and authenicate with a Flex application from a Java client? Any advice or code snippets is much appreciated. Thanks! Michael Foley

RE: [flexcoders] Server Side Cache and AMF
Excellent, thanks. Ollie Seth Hodgson wrote: Flash Player and AIR send AMF requests in the body of HTTP POST requests. The POST method (http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html - section 9.5) is technically not cacheable by HTTP components (proxies, browsers, etc.) unless the AMF endpoint explicitly enables this by setting necessary HTTP response headers to allow caching. I think in general, AMF endpoints do the opposite and set response headers to explicitly disallow caching to deal with old buggy proxies that cache things they shouldn't. Because your Flex app is running in a stateful client, the need for caching along the network path is reduced. Your app can hang onto data from the server as long as you think is prudent, and it can fetch more or refresh existing data as needed. Traditional web apps on the other hand often end up triggering many duplicate requests as the user navigates forward and back through pages, so caching along the network path is essential to protect your servers from inadvertent DoS attacks :) Best, Seth From: flexcoders@yahoogroups.com [mailto:flexcod...@yahoogroups.com] On Behalf Of Mike Oliver Sent: Sunday, January 11, 2009 4:26 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Server Side Cache and AMF What are the pros and cons to using a serverside cache or proxy cache with Flex and AMF?

[flexcoders] Re: Best way to toggle elements in ArrayCollections
Jason,
I'm doing something similar with checkboxes and the DataGrid.
Are you able to turn the visibility of your component on/off ?
Rather than modify the dataset, you may be able to use a checkbox event
to trigger the visibility change of your display component.

This is the dataprovider for another visual component (this is not the

is to change what's contained in the array collection.
My question is, while I can think of ways to do this (adding and

[flexcoders] Flash Detection
Hi, I have a program which has a normal desktop setup (installshield). After install and on launch it launches an IE window and inside it's Flex. Now I want to require minimum version of 10, but it's breaking my program using javascript detection as in http://www.adobe.com/products/flashplayer/download/detection_kit/. My question is, is it possible to detect version of Flash not through the browser? I want to be able to read some registry. Otherwise, can I bypass the automatic detection and upgrade mechanism by any chance? I'm having major problem with the way Adobe is doing it, which is upgrading, closing the window, and relaunching the same page. Can I detect that it's less than 10, than just give user a link (redirect to some other page), without going through how Adobe upgrades inside the browser? Thanks, Mike
[flexcoders] DateField JDBC
It seems odd or even cumbersome to tie the DateField control through to a Date column in a JDBC database using the text property of the DateField. The format out of the DateField doesn't match the format for a JDBC date so you must reformat the 01/21/2009 to 2009-01-21. That's not so tough, but it seems odd that there isn't a method to get the right format string out of the control. The selectedDate is ok, but if you are using a REST interface, then you need to convert that to a string...shouldn't controls be created to serve the most common implementations and isn't backing a form with JDBC one of if not the most common implementation? -- View this message in context: http://www.nabble.com/DateField-JDBC-tp21593640p21593640.html Sent from the FlexCoders mailing list archive at Nabble.com.

into the parameters with
parameters[dsFieldName.substr(0,dsFieldName.length-3)] =
e.currentTarget.itemEditorInstance.selectedItem.data;
and that saves to the database, all great...however, the
editorDataField=selectedItem puts [object Object] into the Grid instead
of the data element.
I tried editorDataField=selectedItem.data but that fails. I tried value
and text but it saves the Label.
So what do I put in the editorDataField to save the 'data' to the Grid
instead of the object string or the label?

Strange. Setting editorDataField to 'value' should work if you have a

The ComboBox won't select the item based on the value of the 'text'
property, so you'll have to do the selection for it, by overriding the
data setter.

super.data = value;

[flexcoders] MySql timestamp column type and Flex DateField
How do I tie a DateField control to a Value Object with a Timestamp column in the database. I am getting java.lang.IllegalArgumentException: Timestamp format must be -mm-dd hh:mm:ss.f at java.sql.Timestamp.valueOf(Unknown Source) at com.corent.odicx.goms.dao.OrdersVO.setEvent_Date(OrdersVO.java:93) the DateField format string only modifies the display. the selectedDate output doesn't seem to have any methods that take a format string to format for Timestamp. I suppose I could just pull the year month and day out of the selected date and format my own string but that seems like a waste and I am basically lazy. anybody have a cool way to handle this?

RE: [flexcoders] FlexBuilder on 64bit machine any good?
I've had pretty good luck with it so far - I have it running on 3 different laptops and 1 desktop PC - ALL are 64-bit Operating Systems. I should say that 2 machines are running Vista x64 and 2 are running XP x64 Edition. One weird part when running on Vista (if you are using ColdFusion) is configuring IIS - it's fairly involved and can be frustrating. Lots of articles on the net though regarding how to set it up. One cool thing too, is Adobe has a 64-bit version of ColdFusion - so it takes advantage of all the RAM. My laptops are all limited to 4 gigs of RAM, but my desktop has 8 gigs. I am still using my previous FlexBuilder.ini file, which of course specifies all the RAM preferences. As far as I know (at least in my case) FlexBuilder and/or Eclipse is still only 32-bit, so they are still bound to the 32-bit limitations. Overall - I had good luck with it.

Re: [flexcoders] Command Proxy
You can still use a command proxy architecture with Adobe AIR 1.5 in the same way you could use it with previous versions of Adobe AIR. It is just a proof of concept, so I havent really done any additional work on it (besisde, c# / .net development is not much fun on Mac). You can grab the source from here: http://code.google.com/p/commandproxy/ and find more info here: http://www.mikechambers.com/blog/2008/01/17/commandproxy-net-air-integration-proof-of-concept/ Does that answer your question? mike chambers m...@adobe.com On Dec 15, 2008, at 7:38 AM, flexaustin wrote: I asked this in an earlier post, but hoping Alex can ask Mike Chambers about the status of the Apollo + Command Proxy project he started.

Do we have this access yet?
[flexcoders] help me settle an argument
I have a colleague that is of the opinion that SQL statements in Java Code such as DAO classes is bad practice, that the SQL statements and parameter tokens be externalized into Contants or property files. I maintain that is not only not necessary in general but given our loosely coupled service oriented architecture the classes are largely not in any sort of complex dependency so modifying code doesn't have the ripples of monolithic desktop or client server applications. So while it is true you can change the SQL statement if needed without changing the code and even change syntax if you need to change databases, how often does that happen anyway? And how often do you change the SQL without having to change the classes? I look at DAO classes from Adobe Labs and Sun Microsystems and see SQL statements in the code so I figure if it is good enough for them it is good enough for us. What say you all? -- View this message in context: http://www.nabble.com/help-me-settle-an-argument-tp20876256p20876256.html Sent from the FlexCoders mailing list archive at Nabble.com.
[flexcoders] Modules and Sessions
We are planning on the following organization for an Application. Base Application this will contain a scalable application with a canvas and an Toolbar across the top. The Application will be secured by user login in a popup form window. The tool bar buttons will load modules in the canvas from separate Module WebApps for ease of Maintenance and flexibility. Before we get too far I wanted to ask this group if there are any gotchas in our plan? Specifically, are we correct that the user session is based on that base application and any modules that load will consistently use the user session in the base application? Are there any coding practices we need for the AMF in this model? We assume the modules and the actionscript for those modules carry the user session the same as if the module was loaded from the same root path as the Base Application, right? Just being cautious.

Re: [flexcoders] Flex 3 - Export to Microsoft Excel?
If you send the data to the server, create the Excel file there, then send the result back to Flex, you will have the full power of the numerous server-side Excel file creation methods at your disposal. If you want the chart in Excel to look the same as it looks in Flex then you might have to convert it to a bitmap first. Either that or recreate the chart on the server. If all you need is a simple copy/paste solution, then the method Paul mentioned would be easier to implement. -Mike Chabot On Mon, Dec 1, 2008 at 1:13 PM, sailorsea21 [EMAIL PROTECTED] wrote: Hi everyone, is it possible to export to Excel?

[flexcoders] Help! - Creating MS Access data source using ColdFusion 8 (64-Bit) w/Win2k3 (64-Bit)
Greetings All - I am currently moving my Flex Application (which uses ColdFusion as the backend) to my customer's production server - and I am coming to grips with a frightening discovery: Microsoft has decided to drop JET support, for servers running in 64-Bit mode. For some reason, this also translates to ADOBE not providing a native Access ODBC Driver in ColdFusion 8 (64-Bit Edition). I understand that there comes a time in the software business, where we must abandon older technologies in favor of new. However, there is usually some advanced notice given, in addition to backwards compatibility options for people that simply can't conform to the new ways. As a company, WE have upgraded all of OUR servers software, to the latest technologies. But that doesn't change the fact that we have CUSTOMERS that provide data to us, using virtually the only portable Database format available (an Access .MDB file). I know this is the FlexCoders list and this is largely a ColdFusion question, but I can only assume that a large number of you have been faced with this problem it makes sense to ask for help here. With that said, has anybody come across any solutions, that would allow for creating an Access data source using ColdFusion 8 running on Windows 2003 Server (in a 64-Bit environment across the board)? If a solution isn't found on this, heads will fly around here - as huge investments have been made in order to launch this Flex Application. Thank you in advance for any information that could help shed some light on this problem. Mike
Re: [flexcoders] ArrayCollection
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Tracy Spratt wrote: The issue is that there is only one “lastResult” for the entire framework. “There is only one result” No, this is not correct. Because they are asynchronous, there can be multiple pending RPC data calls. There is no assurance that the first RPC call is the first returned. I guess I just have not developed large enough applications to see what you are stating here. I normally create a HTTPService object then call 1-2 asynchronous calls depending on user interaction with the app. Between the time the result returns, lastResult is set, the result event is dispatched, calling your handler, and your handler gets to the line that uses lastResult, it is very possible that another result has returned, overwriting the value in lastResult. Typically it is actually set to null by the framework, rather than sneaking in some other data, but that is just as dangerous. This was a real issue in a thread six or eight months ago. This all really depends on how you develop the application. I am not saying you are wrong or stating something incorrectly, just that this example is not relevant to most people creating small/medium apps. Most people are doing good to even have a single HTTPService object within their code. If you only call a single RPC at a time, there will be no problem, but complex apps often have many outstanding calls an a given moment. Ah, I see. I appreciate the insight. Why take any risk? Is there some reason you **like** lastResult over using the event.result object? I am not taking a side on anything really. I am just stating that in my little experience, as well as documentation and other resources read, that the lastResult-method is used by the vast majority. I personally appreciate you explaining the lastResult vs. event.result methods. Tracy Thanks Tracy. Mike Duncan ISSO, Application Security Specialist Government Contractor with STG, Inc.

I am not quite sure by what you mean ...are not garrunteed that it will
have the value in the result you expect. There is only one result. And,
by dangerous, are you talking about a memory leak or something?
If there is a case when I get no results, then I can understand this
logic, but in my case, there is always at least one result. A single
child within the root element of the returned XML that is.
I appreciate the heads up though.

In most cases it will work ok but the correct way is:
scans = new ArrayCollection([event.result.vector.scan]);
lastResult is intended only for use in binding expressions.
