[flexcoders] How do I dispatch an everything PropertyChangeEvent on this?
Hi guys, Disclaimer: this is probably a stupid question, but I've been trying to figure this out for way too long! I've got some code that does all sorts of things to this.foo, this.bar, and this.baz etc etc. At the moment I'm dispatching several standard PropertyChangeEvents as I change fields. What I'd like to do is once I've finished all my voodoo, dispatch a single event that says everything needs to be updated, but I need to do it to this rather than on a reference in a parent object, as it's a non-visual component that has no idea where it sits in the object graph.

public class FooBar extends EventDispatcher {

//Pay attention to me!

RE: [flexcoders] ShowDataTip makes charts impossible to destroy arrgghh!
Not sure, how you are cleaning up your charts, but datatips are part of the systemManger.toolTipChildren. The best way to get rid of datatips is to position the mouse pointer where there are no items, which would make the number of datatips on the chart to be zero, which will remove the existing datatip children in InstanceCache's set count method by calling removeChild method. The src of datavisualization (which has charts, advanced data grid) should be in your sdk\lib\DMV-source.jar, which should get extracted once you apply your license. -Sunil From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Ryan Sent: Thursday, May 15, 2008 11:13 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] ShowDataTip makes charts impossible to destroy arrgghh! hi- we are working on using the Profiler in FlexBuilder 3 to improve our app's memory use.

This involves cleaning up a tangled web of references to get them out of memory. this works fine, except for charts which have the showDataTips property enabled. When the chart has been moused over and the dataTip shown, destruction becomes impossible!

Re: [flexcoders] invalid column widths in DG before render.
In Flex, if a UI component has not been displayed, it has not yet measured it's size. This is what happens with the DataGrid as well. You could set the creationPolicy to all and wait for the creationComplete event before you retrieve the column widths and height.

Re: [flexcoders] Re: Include images in SWC via compc
You can inspect the contents of the SWC with WinRar or a similar tool. It is
just a zip-like container. Within it you will find at least 2 files:
library.swf - This swf contains all compiled information
catalog.xml - This file contains information about the contents of the swf
As for information about the swf, this is described pretty well in the
catalog.xml. If you want more information,
there are a few applications that can inspect the contents of an swf. Some
are even written in Adobe AIR.

In Flexbuilder, I had the images checked on the Assets tab, and the

-locale en_US -source-path=../locale/{locale}
-include-resource-bundles=images,UIStrings -include-file myapp.css
../stylesheets/myapp.css
Is there really no wildcard way to include all the images in the SWC
from the command line without listing them explicitly in a config

Assets tab?
The properties files references the images like this
zoom=Embed(images/zoom.png)
I assume we would have to use images/zoom.png as the name in a

[flexcoders] itemFocusout in datagrid
Hi friends,
Iam writing itemFocusOut event for my data grid and the code is as
follows.
public function focusOutHandlerEvent(event : DataGridEvent):void{
var validateValue : NumberValidator = new NumberValidator();
var validationResult : ValidationResultEvent;
validationResult =
validateValue.validate(event.itemRenderer.data.number);
if(validationResult.type ==ValidationResultEvent.INVALID){
errMsg=invalid;
}else{
errMsg=valid;
}
}
// Item Edit End Event
public function preventDefaultMethods(event : DataGridEvent):void{
if(event.reason ==DataGridEventReason.NEW_COLUMN ||
event.reason==DataGridEventReason.NEW_ROW ||
event.reason==DataGridEventReason.CANCELLED){
// keep the data as it is.
return;
}
if(errMsg==invalid){
event.preventDefault();
}
}
Is this a proper way to implement the itemFocusOut event. Moreover when i
enter the 'Enter' key it throws an error #1009, findNextItemRenderer()

Hi Jeffrey,
You shouldn't attempt to send UI components from one app to another;
you just need to send enough info to the peer for it to simulate the
same behaviors as you're doing locally. There's no out-of-the-box

Try sending identifiers for the component you're dragging, as well
as for the drop target. In your messageHandler() method in the
receiving app, use these identifiers to get references to the local UI
components that match, and reparent the 'dragged' component under the
local 'drop target' component. The reparenting could be simple and
direct, and you could try to animate it once you get the basic
scenario working if you wanted (you know where the 'dragged' component
starts and where it ends up so maybe you could do a straight line
animation to simulate the original drag and drop). Sorry, don't have
time to code up anything at the moment.

You can put anything you like into the body, or headers, of an
AsyncMessage; a string, a number, an anonymous Object, a typed Object
(if you use a typed Object be sure to tag it with [RemoteClass]
metadata). You can control which subscribed Consumers receive the
message by using the Consumer.selector property (a SQL-92 expression
evaluated on the server against the headers of incoming messages; if
the message headers satisfy the expression the message will be
delivered to the Consumer), or by using the Consumer.subtopic property
to subscribe to a subtopic (or range of subtopics) within a
destination and using the Producer.subtopic property to control which
specific subtopic sent messages go to.
When building 'screen-sharing' style applications like this, you
need to really keep network latency in mind. Some GUI frameworks will
'summarize' events before handing off to even local processing (i.e.
collapsing a bunch of individual key strokes into a summary string
containing all the characters typed since the last event dispatch and
just dispatching that single event). This becomes even more important
when you're considering sending lots of high frequency events over the
network to peers.
In this case, I'd recommend sending a single message to subscribed
peers on drop complete, indicating which component was dragged and
dropped along with its final location. You can then either just
reparent the corresponding component immediately on the receiving
peer, or animate it along a simple path. There are lots of options
with this sort of thing, but you shouldn't try to generate and send a
message for each pixel it is dragged.
Hope that helps,

[flexcoders] Rich Text Editor - putting the toolbar above the textArea
There seems to be some weird things going on with the RichTextEditor layout that i cant quite understand. If you look at the RichTextEditor class (F3) its actually an mxml file made up of a Panel with two child components (TextArea and ControlBar containing a ToolBar). When i do traces i get this: trace(rte.numChildren) // 1 trace(rte.getChildAt(0)) // textArea trace(rte.getChildAt(1)) // throws error So, its ignoring the ControlBar as a child component - even though you can see it in the MXML. Given that the ControlBar has no id, this makes it difficult to target since you cannot do so directly via actionscript OR the Display List as evidenced above. The only way i can get to it is via teh parent property of teh RichTextEditor's tooBar property (as i said above, the toolbar is a child of the untargetable ContolBar which can also be referenced through the RichTextEditor property toolbar) eg. rte.toolbar.parent // this is a reference to the ControlBar With this in mind - the only way i can work out how to swap the components around is the following: var displayObj:DisplayObject = rte.toolbar; rte.toolbar.parent.removeChild(displayObj); rte.addChildAt(displayObj, 0); This seems like a clumsy workaround. Is my understanding of the AS3 Display List flawed, is there are more direct way i am missing?

RE: [flexcoders] coldfusion and Flex?
To my knowledge, no, you can't have CF7.02 and CF8 running on the same box, except maybe if one of them was a standalone instance or something, but it would be messy, and I doubt its worth the trouble. If you're really concerned that the upgrade is going to break something, then use VMWare or similar product to build your CF8 evaluation instance and test your code there. My experience tells me that as far as remoting is concerned, there's not a lot of difference. As far as project settings, if you're using default services-config.xml I doubt there will be an issue.

[flexcoders] Re: AIR drag/drop via asynchronous download
I'm trying to create a drag/drop app where the data to be 'dropped' is actually on a remote filesystem. I'm using Cairngorm I have a Command that is fired by NativeDragComplete in the View and downloads the selected files to a temp directory, then populates the Clipboard with an AIR File list of those files. So far so good, but obviously the drag/download operation is asynchronous, so can I create some kind of callback to the drag handler in the View so that it knows when the clipboard data is ready, or just tell the Command where the drag went? Or is there a better way to do this?

The 'is' operator works on values. A value like 5 'is' both an int, a

values for each of these types.
But I would expect a var declared as

Well, it turns out that doesn't work either if the int is positive. If

[flexcoders] Is there a way to change the timezone of Date object in Flex 1.5?
Hi, I'm working on an application with Flex as front end. I need to interact with back end only with GMT+0 date times or with the same timezone which my server is set up on. But as I've found out, any datetime instance created in Actionscript is by default will have the time zone set to system's local time zone. Also when this date is recieved on server as a result of time zone offset the date may skip a day or lag a day to what user has specified. Similar problem happens when recieving the date also, that is, any GMT +0 time which is received is converted to local time before displaying on the screen :(. Since i'm using DateField to get user input, any date chosen from DateChooser popup will be set to local time zone. Also the parseFunction property which can be set on a DateField is invoked only when the date is changed by typing manually into the text box, so we have no control over what is set through the DateChooser popup. Let me explain exactly what problem I am dealing with - Suppose the the server timezone is MST (GMT - 7) and the client machine is set on IST (GMT + 5:30), so there is a time difference of 12:30 hrs between the client and server. Now if a Date object is created and sent to server from the client machine any time before 12:30 PM (IST, say 11:00 AM on 22 May), flex gatway performs the time conversions according to the timezones of client and server and subtract 12:30 hrs from the time passed from the client and therefore the time goes to the previous day and the date received on the server is 21 May, 10:30 PM, which is not the date client has sent. So to resolve this issue, I want to set the timezone of the Date objects to what is there on the back end, so that no conversions take place while passing on the Date objects to the server. I know the Date object has timezone information relative to GMT and we can set the time to GMT time using Date.UTC(), but it does not change the timezone to GMT which will not serve the purpose. What I wanted to know if there is a way we can change the timezone of the Date object and if anyone has been able to do it (either with Flex 1.5 or 3.0)? If yes, could you please be generous enough to share the solution you appllied... Thanks

[flexcoders] Binding Model to selectedItem property not updating
I'm currently refactoring a small application to be more MVC and am running
into a few binding issues.
In my Model, I store all my dataProviders, which are Arrays (because they
will not change) and I also have a typed object that stores my form state as
individual objects. In my View, which is mostly a bunch of ComboBoxes, I
have set the dataProvider to bind to the arrays in the Model, and set the
selectedItem to bind to the form state properties. I added a button which
will update the form state for one of the properties when clicked, which
works (the ComboBox updates to the expected value) the first time, but not
on subsequent clicks. I've attached a listener to the valueCommit event on
the ComboBox, and it does fire the first time.
I've tried changing the Model to use ArrayCollections instead, and used the
Collection API to try and update the selectedItem (by setting the form state
model to the value of a getItem() call) but that isn't working either.
Is there a better way to handle storing and binding form state in a well
designed Flex app? I'm not using a framework, and don't really want to at
this point in time (the app is fairly small, and the deadline is approaching
quickly.)
Any help or insight is greatly appreciated!
- Ken
Code snippets:
The ComboBox:
mx:FormItem label=Age
mx:ComboBox id=age dataProvider={model.ageList} rowCount=10
selectedItem={model.quotingFormState.age} /
/mx:FormItem
The function called to update the ComboBox (works on first click only):
private function updateAge():void {
model.quotingFormState.age = model.ageList[5];
}

RE: [flexcoders] LCDS and channel usage
Hi Robert, Chances are you're trying to use DataService with auto-sync enabled over an AMFChannel that doesn't have polling enabled; if that's the case you won't receive any pushed updates. Auto-sync can be disabled for a DataService (say you're just doing CRUD interactions with the server and don't need pushed data in your app), and in that scenario using an AMFChannel with polling disabled works fine. Any channel type can be used with any service component. There's a general overview of the channel options and why you'd prefer one over another here, and the doc team is currently working on lots of improvements to the official docset in these areas: http://www.dcooper.org/blog/client/index.cfm?mode=entryentry=8E1439AD-4E22-1671-58710DD528E9C2E7 In terms of which channels are used by the client to interact with the server, this is defined by the order that Channels are assigned to your client-side ChannelSet (if you set things up directly in code). Or in the more automatic case, it's based on your services-config.xml file default-channels config, or a specific service's default-channels or a specific destination's channels. The best practice is to just define this list once at the top level in services-config.xml within the services section: services ... default-channels channel ref=rtmp/ channel ref=amf-polling/ /default-channels /services This default setting is applied to all services and destinations, unless you override at a specific service or destination. There's really no good use case to do that though, so just define the set of channels clients should use here at the top level. This list of Channels is what is burned into your swf when you compile with the -services option, and it's used to dynamically construct a ChannelSet on the client at runtime. There's no magic in the ChannelSet to determine which Channel from among the set to connect with - it starts with the first, and advances through until it successfully connects. If it looses connectivity, it continues through the list from its current position. So this component provides reconnect and high-availability by falling back through its options. So for the example above, the client will first try to connect via RTMP to your server-side RTMP endpoint's URL, and if that fails (say the client has a firewall blocking that port), it will fall back to a connect attempt over your AMFChannel (which has polling enabled). Hope that helps, Seth From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Robert Csiki Sent: Friday, May 16, 2008 8:33 AM To: flexcoders@yahoogroups.com Subject: [flexcoders] LCDS and channel usage Hi there, What channels are compatible with what service objects?

Also: for each of the available services (DataService, HttpService, WebService, RemoteService), whenever they support multiple channels, what's the order these channels are being tried by the framework?

RE: [flexcoders] Re: RTMP port 2038
The RTMP endpoint runs its own internal server process to handle RTMP connections. This process needs to bind a port to accept connections on. If you're running multiple web apps on the same server, each with their own RTMP endpoint, these endpoints need to use unique ports (you can't have multiple processes bind the same server port to accept connections on). We deploy into a Java server as a web app which has pros and cons, and while the pros outweigh the cons, in this specific case RTMP configuration is not as trivial as it would be in a perfect world when you're deploying multiple apps in the same container. For servlet-based HTTP traffic, the servlet container is handling all network connections and IO, and routes inbound requests to the proper web app based on the requested URL; the web apps themselves aren't handling any network connections or HTTP traffic directly. This means that all of your web apps can be exposed on a single HTTP port (80 or 8400 or whatever) uniformly. But for RTMP, where we have to handle the networking ourselves, there's no safe way to have a single RTMP endpoint that services connections for any and all web apps because we're running within the context of a specific web app rather than as core code in front of all the web apps, and web application startup order isn't guaranteed to be deterministic and individual apps can be undeployed/redeployed at runtime making sharing a single RTMP endpoint defined in one web app with other web apps something we haven't tried to support - there are all kinds of ways for things to go wrong with that. An analogy would be trying to run each of your web apps in a unique instance of your Java server on the same machine. Try starting up multiple instances of Tomcat, each hosting just one of your web apps, where each Tomcat instance is configured to handle HTTP traffic on port 8400 - it doesn't work. So you need to define a unique port for each RTMP endpoint, and you'd need to build your client for each web app to use the proper corresponding port.

In my Model, I store all my dataProviders, which are Arrays (because
they will not change) and I also have a typed object that stores my form
state as individual objects. In my View, which is mostly a bunch of
ComboBoxes, I have set the dataProvider to bind to the arrays in the
Model, and set the selectedItem to bind to the form state properties. I

expected value) the first time, but not on subsequent clicks. I've
attached a listener to the valueCommit event on the ComboBox, and it
does fire the first time.
I've tried changing the Model to use ArrayCollections instead, and used
the Collection API to try and update the selectedItem (by setting the
form state model to the value of a getItem() call) but that isn't
working either.
Is there a better way to handle storing and binding form state in a well

My question is, is there any way to get code hinting for MXML assets working in included as files? Often in my projects I use a pseudo-code behind for MXML files by simply including the AS code in the source prop for the Script tag in the MXML file. Say in CustomComponent.mxml, we have mx:Script source=CustomComponentCode.as/ ... mx:Button id=daBtn/ The problem is, in CustomComponentCode.as, I don't get code hinting for MXML assets declared in CustomComponent.mxml -- daBtn does not trigger code hinting, which is a real pain. I suppose one solution is to declare all component instances in AS, but that completely defeats the purpose of MXML. For smaller components, I usually land up coding the entire component in one MXML file, then separate out the AS from the MXML when it's done, but this can lead to spaghetti code, so it would be great if I could use the two files right from the start. I don't want to get into a debate about code behind techniques; I know there are other, more robust ways of using code behind such as using bona-fide classes, but the include technique seems a lot more logical and straightforward to me.

[flexcoders] SQL Lite syntax issue, need something cleared up regarding SELECT
While working on the login functionality of the application I'm
developing, I noticed that SQL seems to be interpereted differently
than what I'm used to. Here's my current select statement that I'm
using for validation:
sqlText = SELECT * FROM Up18Technicians WHERE TechName = + userName
+ AND Password = + pass;
Which translates to:
SELECT * FROM Up18Technicians WHERE TechName = Ross AND Password = 358029
Now, when the application gets to the execute portion, it throws this
error:
SQLError: 'Error #3115: SQL Error.', details:'no such column: Ross',
operation:'execute'
at flash.data::SQLStatement/internalExecute()

at
MatMgr_Proto/__btnLogin_click()[C:\Tech_Connect\MatMgr_Proto\src\MatMgr_Proto.mxml:18]
This indicates that it is trying to find columns by the name of what
was entered instead of trying to find values in those columns matching
what I entered. I looked up SQL as its understood by SQL lite, but it
seems a bit confusing and I'm unsure if it's even the problem. If it
is, then I'm just wondering if it may have something to with perhaps
the AND keyword isn't understood or maybe there's something up with
how I'm using the WHERE clause.
Here's the function I'm using to perform this in case it helps:
public function techLogin(userName:String, pass:String):void
{ //This loads information needed to login technicians
sqlText = SELECT * FROM Up18Technicians WHERE TechName = +
userName + AND Password = + pass;
trace(sqlText);
selectStatement = new SQLStatement();
conn = new SQLConnection();
selectStatement.sqlConnection = conn;
conn.open(dbFile);
selectStatement.addEventListener(SQLEvent.RESULT,
selectTechLoginResult);
selectStatement.addEventListener(SQLErrorEvent.ERROR, errorHandler);
selectStatement.text = sqlText;
selectStatement.execute(); //Error happens here, doesn't go any further

Subject: [flexcoders] SQL Lite syntax issue, need something cleared up
regarding SELECT
While working on the login functionality of the application I'm
developing, I noticed that SQL seems to be interpereted differently
than what I'm used to. Here's my current select statement that I'm
using for validation:
sqlText = SELECT * FROM Up18Technicians WHERE TechName = + userName
+ AND Password = + pass;
Which translates to:
SELECT * FROM Up18Technicians WHERE TechName = Ross AND Password = 358029
Now, when the application gets to the execute portion, it throws this
error:
SQLError: 'Error #3115: SQL Error.', details:'no such column: Ross',
operation:'execute'
at flash.data::SQLStatement/internalExecute()
at flash.data::SQLStatement/execute()

10]
at
MatMgr_Proto/__btnLogin_click()[C:\Tech_Connect\MatMgr_Proto\src\MatMgr_Prot
o.mxml:18]
This indicates that it is trying to find columns by the name of what
was entered instead of trying to find values in those columns matching
what I entered. I looked up SQL as its understood by SQL lite, but it
seems a bit confusing and I'm unsure if it's even the problem. If it
is, then I'm just wondering if it may have something to with perhaps
the AND keyword isn't understood or maybe there's something up with
how I'm using the WHERE clause.
Here's the function I'm using to perform this in case it helps:
public function techLogin(userName:String, pass:String):void
{ //This loads information needed to login technicians
sqlText = SELECT * FROM Up18Technicians WHERE TechName = +
userName + AND Password = + pass;
trace(sqlText);
selectStatement = new SQLStatement();
conn = new SQLConnection();
selectStatement.sqlConnection = conn;

[flexcoders] Re: RTMP port 2038
Thanks Seth, you've explained it pretty clear. I got it - unique RTMP port is required for each RTMP endpoint. Robert --- In flexcoders@yahoogroups.com, Seth Hodgson [EMAIL PROTECTED] wrote: The RTMP endpoint runs its own internal server process to handle RTMP connections. This process needs to bind a port to accept connections on. If you're running multiple web apps on the same server, each with their own RTMP endpoint, these endpoints need to use unique ports (you can't have multiple processes bind the same server port to accept connections on). We deploy into a Java server as a web app which has pros and cons, and while the pros outweigh the cons, in this specific case RTMP configuration is not as trivial as it would be in a perfect world when you're deploying multiple apps in the same container. For servlet-based HTTP traffic, the servlet container is handling all network connections and IO, and routes inbound requests to the proper web app based on the requested URL; the web apps themselves aren't handling any network connections or HTTP traffic directly. This means that all of your web apps can be exposed on a single HTTP port (80 or 8400 or whatever) uniformly. But for RTMP, where we have to handle the networking ourselves, there's no safe way to have a single RTMP endpoint that services connections for any and all web apps because we're running within the context of a specific web app rather than as core code in front of all the web apps, and web application startup order isn't guaranteed to be deterministic and individual apps can be undeployed/redeployed at runtime making sharing a single RTMP endpoint defined in one web app with other web apps something we haven't tried to support - there are all kinds of ways for things to go wrong with that. An analogy would be trying to run each of your web apps in a unique instance of your Java server on the same machine. Try starting up multiple instances of Tomcat, each hosting just one of your web apps, where each Tomcat instance is configured to handle HTTP traffic on port 8400 - it doesn't work. So you need to define a unique port for each RTMP endpoint, and you'd need to build your client for each web app to use the proper corresponding port.

[flexcoders] Panoramics XDEPTH HDRI 32bit Images
Hi Everyone,
I would like to bring peoples attention to the 32 bit XDepth (
www.xdepth.com ) image format, and if possible get some help on how
to get this to work within FLEX.
I suspect it won't be possible at the moment.
In the ideal scenario, I would like to combine a panoramic image in
the XDP format, as the .xdp image can be renamed to .jpg its easy to
bring the image into flex or any other program and edit with it as
normal.
The developers of XDepth have provided me with the code to use in a
normal web page, but I have no idea if it can be used in flex.
or If it can be integrated to control the images once it has passed
through Flex or Pano2VR
I have a number of 32bit images and panoramics (which I am not sure
if the panoramics are now only 8bit after they pass through the pano
creation software) , I assume so???
If I am not mistaken the only way to use the panoramas is probably
flash paper or something
If anyone would like access to these image for testing purposes I
would be happy to provide some.
this is the only code i have
object id=xdcont classid=clsid:AB21F56B-651E-4644-994D-

RE: [flexcoders] Is the context-root value burnt into SWF?
A context root is a Java servlet-ism, which allows the container to route
incoming requests to the correct web app. In HTML-land if you're using relative
URLs, you generally never have to worry about this because the right value will
be used automatically. It's a little more complicated for a non-HTML client.
The context root for a web app can either be empty (i.e. /) or non-empty (i.e.
/MyApp), and on the client when a swf loads, it can inspect its URL but it
doesn't have any way to know what the server-side context root is. The
MessageBrokerServlet that processes HTTP-based requests from Flex clients is
not relative to where the swf was loaded from. You can define its path, which
will generally be something like:
http://{server}:{port}/{context.root}/messagebrokerservlet, but it could be
anything. To send a request to it successfully, the client needs to use the
correct context root. Take your URL below for example,
http://localhost:8080/MyApp/..., is the context root / or is it /MyApp - who
knows? Only the server. So unlike server name and port, the swf can't
dynamically determine the correct context root value at runtime on the client.
This means you need to either:
1. Specify it at compile time by hardcoding the proper context root into the
URL in your services-config.xml file, or by using a {context.root} token in
your URL in services-config.xml and passing the desired value at compile time
using the mxmlc -context-root flag.
2. Hardcode it into your client side ActionScript code.
3. Use the web tier mxmlc compiler which can replace a {context.root} token
with the correct value using HttpServletRequest#getContextPath() when you
request a .mxml in the browser

[flexcoders] bug in setMonth() method?
Hi, all;
I'm working on making an app that will allow users to navigate from
one month to the next based on a start date and end date. I noticed
some interesting effects with the date object and days that fall
outside the 1-31 range (http://tinyurl.com/5qc46j), so I thought I'd
try something similar with months.
What I find is if the current month is 11 and you add 1 to it, you'll
actually wind up with a date that's not in the _next_ year, but one
in the year following.
Here's my code
public function makeDisplayedMonths(beginDate:Date, endDate:Date):void
{
var today:Date= new Date();
//set up date for loop
var parseDate:Date = beginDate;
//equalize parsedate and enddate
parseDate.setDate(1);
endDate.setDate(1);
while (parseDate = endDate) {
//update date
parseDate.setMonth(++parseDate.month);
trace(parseDate, endDate);
}
}
the trace is this
Tue Jul 1 00:00:00 GMT-0500 2008 Thu Jan 1 00:00:00 GMT-0600 2009
Fri Aug 1 00:00:00 GMT-0500 2008 Thu Jan 1 00:00:00 GMT-0600 2009
Mon Sep 1 00:00:00 GMT-0500 2008 Thu Jan 1 00:00:00 GMT-0600 2009
Wed Oct 1 00:00:00 GMT-0500 2008 Thu Jan 1 00:00:00 GMT-0600 2009
Sat Nov 1 00:00:00 GMT-0500 2008 Thu Jan 1 00:00:00 GMT-0600 2009
Mon Dec 1 00:00:00 GMT-0600 2008 Thu Jan 1 00:00:00 GMT-0600 2009
Fri Jan 1 00:00:00 GMT-0600 2010 Thu Jan 1 00:00:00 GMT-0600 2009
Note that it goes from Dec 1 2008 to Jan 1 2010, skipping 2009
altogether.
Obviously now I know this I can code around it, but it seems like it
should either throw an error that the month is out of range or just
keep incrementing.
Or have I missed something here?
Thanks;
Amy
[flexcoders] Re: Is the context-root value burnt into SWF?
Thanks Seth, I understand it's different in Flex world.
So does this mean customers are stuck with the context root we used when
compiling the application (e.g. which is equals to the application WAR
filename, less the extension)? We do not package the source code, all
they get is the SWFs and some html wrappers.

MyApp.war, depoly it on my Tomcat, startup tomcat, access the
application using http://localhost:8080/MyApp, everything works fine (I
have an index.html there that serves up the SWF)
Now, if I want to deploy using a different context root for my
application (say MyApp1)... call it using the URL
http://localhost:8080/MyApp1 ... nothing would work this time. The SWF
still gets loaded, and that's it. It seems this context-root value
that's set in flex_config.xml gets somehow burnt in the SWF? what can I
do to have the app running under a different context root, without the
need to rebuild the SWF?
Also, a question: why this context-root configuration is required in
Flex environment? An application normally auto-detects it's context root
at runtime. An application is usually untied from a specific context
root and can be deployed using any context root.

[flexcoders] Re: Respecting backgroundImage aspect ratio
Hi Greg, Without going under the hood, you'll probably want to add a couple more layers to your component. The backgroundImage propeties of a container don't allow you to use the maintainAspectRation property. However, the Image control does. So, one way that you can work around this is to use a Canvas as the main component container and layer a VBox on top of an Image (used for the backgroundImage). This gets trick sometimes; depending on how you set the parent and/or child dimensions. But, if you set either the Image height or width exclusively, and use the maintainAspectRatio, the image will scale correctly. -TH --- In flexcoders@yahoogroups.com, Greg Hess [EMAIL PROTECTED] wrote: Hi Folks, Our application lets a user specify an image to use as a background for a component. We need to scale the image to fill the VBox container (max width or height) respecting the aspect ratio of the image. I have been setting the backgroundImage, and backgroundSize=100% styles on the VBox but the image is being stretched. How can I do this? Cheers, Greg
RE: [flexcoders] Re: Is the context-root value burnt into SWF?
What about allowing your customers to edit the HTML wrapper to pass a flashvar
in to the swf that explicitly defines the context root they're deploying to?
Your code could check for this value and do your own string replace of any
{context.root} tokens in your channel uris with this value before connecting
(be careful when handling empty context root values).

RE: [flexcoders] Re: LCDS and channel usage
Probably because if you're only using just one or the other in your app (data management or remoting) those would be the preferred default channels. But if you're using multiple services in the same app, which is common, you'd want to avoid defining unique channels for each service and instead use a common set of default channels across all of them.

route incoming requests to the correct web app. In HTML-land if you're
using relative URLs, you generally never have to worry about this
because the right value will be used automatically. It's a little more
complicated for a non-HTML client. The context root for a web app can
either be empty (i.e. /) or non-empty (i.e. /MyApp), and on the client
when a swf loads, it can inspect its URL but it doesn't have any way
to
know what the server-side context root is. The MessageBrokerServlet
that
processes HTTP-based requests from Flex clients is not relative to
where
the swf was loaded from. You can define its path, which will generally
be something like:
http://{server}:{port}/{context.root}/messagebrokerservlet, but it
could
be anything. To send a request to it successfully, the client needs to
use the correct context root. Take your URL below for example,
http://localhost:8080/MyApp/..., is the context root / or is it /MyApp
-
who knows? Only the server. So unlike server name and port, the swf
can't dynamically determine the correct context root value at runtime
on
the client.
This means you need to either:
1. Specify it at compile time by hardcoding the proper context root
into the URL in your services-config.xml file, or by using a
{context.root} token in your URL in services-config.xml and passing
the
desired value at compile time using the mxmlc -context-root flag.
2. Hardcode it into your client side ActionScript code.
3. Use the web tier mxmlc compiler which can replace a
{context.root}
token with the correct value using HttpServletRequest#getContextPath()
when you request a .mxml in the browser

Subject: [flexcoders] Is the context-root value burnt into SWF?
Hi there,
Say I'm using a context root value MyApp when compiling my
LCDS-based Flex application. I package everything into an archive
called
MyApp.war, depoly it on my Tomcat, startup tomcat, access the
application using http://localhost:8080/MyApp, everything works fine
(I
have an index.html there that serves up the SWF)
Now, if I want to deploy using a different context root for my
application (say MyApp1)... call it using the URL
http://localhost:8080/MyApp1 ... nothing would work this time. The SWF
still gets loaded, and that's it. It seems this context-root value
that's set in flex_config.xml gets somehow burnt in the SWF? what can
I
do to have the app running under a different context root, without the
need to rebuild the SWF?
Also, a question: why this context-root configuration is required in
Flex environment? An application normally auto-detects it's context
root
at runtime. An application is usually untied from a specific context
root and can be deployed using any context root.
Thanks, Robert
[flexcoders] Re: Cannot install featurecom.adobe.flexbuilder.feature.standalone 3.0.194161
Perhaps you could get your admin to come over, give you full admin rights, install FB3, then reduce your rights again? or is that E a B? ;-) more like a PITA - or rather a snowflakes chance in hell. I bring this up because (like a mine canary) I may not be the only one this happens to. What I'm getting at is that I already have enough perms to install software as an Administrator (like Apache, ColdFusion, video card drivers and other stuff) but FlexBuilder fails. So far it's the only install to do so. there must be something in the install process that's choking, and at a guess it's tied up with how the FB libraries are added to the core Eclipse. I'm going to try a seperate Eclipse + FB plugin install on Monday to see if that works. It's a pity I didn't have access to this environment during the FB3 beta - it might have come in handy as feedback.
[flexcoders] Trying to apply scale9grid to an image loaded at runtime
I need to be able to load an image, allow the user to specify the scale9grid values, and then scale the image. I've tried a bunch of different things but either the scale9grid values aren't used or I get an invalid parameter exception. Is it possible to do this? Thanks, Tom
[flexcoders] How to do Flex,coldfusion and LCDS?
Hi, Please give me a idea how to set up the development enviroment for the purpose. I use Flex with remote object before but I do not have idea for developing with LCDS. Please let me know if you need some url for this. Thanks Mark

Hi Greg,
Without going under the hood, you'll probably want to add a couple more
layers to your component. The backgroundImage propeties of a container
don't allow you to use the maintainAspectRation property. However, the
Image control does. So, one way that you can work around this is to use
a Canvas as the main component container and layer a VBox on top of an
Image (used for the backgroundImage). This gets trick sometimes;
depending on how you set the parent and/or child dimensions. But, if
you set either the Image height or width exclusively, and use the
maintainAspectRatio, the image will scale correctly.

Hi Folks,
Our application lets a user specify an image to use as a background
for a
component. We need to scale the image to fill the VBox container (max
width
or height) respecting the aspect ratio of the image. I have been
setting the
backgroundImage, and backgroundSize=100% styles on the VBox but the
image
is being stretched.
How can I do this?
Cheers,
Greg
