can you show the code where you set date on datagrid?

Subject: [flexcoders] Working with date/Time in FB
There's something I'm not completely understanding yet. I've coded
around it but I'm not feeling comfortable with my solution.
My FB4 app links up with CF9 and I'm working with dates and times.
When I pull up a date from CF9 into a FB4 datagrid the time shows off by
one hour. Eg.
2010-06-01 23:30:00 is in my MySQL DB (11:30pm). When I load the time
from CF9 to a FB4 dataGrid it shows 2010-06-02 as the date and 12:30:00
as the time so the day advances because the time is one hour ahead.
My initial thought is that it's something to do with either the timezone
or day light savings time. Right now I just set a variable that I call
DST, set it to -1 and then subtract it from the date before I manipulate
the date and time.
Even getting the UTC date/time then using the timezone still gets it off
one hour without accounting for DST (that's why I think I'm dealing with
daylight savings time)
Can anyone confirm this or shed any light on what is going on? I don't
want FB to worry about date and time; I want to do all of this through
CF9 on the server side. I don't want to worry if the user has their
computer set correctly for their timezone and daylight savings time. I
just want FB to display the time it pulls directly from the CF9 object I
provide it.
Thanks a ton.

[flexcoders] Job opportunity in Atlanta
Flexcoders, My employer, the Atlanta engineering division of an American manufacturer of international consumer products, is looking for help with a Flex development project. We want a contractor that can start immediately, and the project is long term, with serious potential for permanent hire. I would prefer someone with a strong animation and effects background (a Flash guy would be ideal), to complement my data-flow orientation, but any experienced Flex developer will be able to do the job. This is not an entry level opportunity. We need someone who can be immediately productive. I'd say four years of full-time Flex experience is the minimum, but if you got to that proficiency level in three years, I'd be ok with that. If you are interested, do NOT respond to this message. This is a technical forum, and has enough traffic already, but I doubt anyone will object to this single posting of a real opportunity. Instead, reply to the email address below. It is the company HR person, not me, but if you are a serious candidate, your response will get to me. Note, the physical location is actually in Alpharetta, just off exit 12 on 400.

RE: [flexcoders] What is the best Way - Multiple DataProvider's or one?
As usual, it depends. If your data is small enough and static enough, get it all at once and avoid the inherent latency of remote data retrieval entirely. But rarely is data retrieval or processing the performance bottleneck. Most often it is screen rendering, and TileList can be a hog, depending on how you have implemented it. (How many and how complex are the tiles?) Use getTimer() to benchmark the various steps to verify where your bottleneck actually is. Regardless, consider disabling the TileList while it is rendering. I am not sure what the best event to use to indicate rendering complete will be. Knowing when a screen is fully rendered is not a simple thin, but I do not think you have to get the very latest event, just late enough to prevent clicking on stale data.

In my app I have a tilelist with an array collection as it's dp which is populated via remote xml from a mysql database. When a user clicks a certain category button in my app it sends a request to the server to tell it which category items the user wants to see which in turn changes the array collection that populates the tilelist so it shows items within that category. The thing is though this seems to be a bit unreliable as it means the user has to wait for a while for the dataprovider to change so sometimes they click to the next category and the items from the previous category are still shown in the tilelist. Is it better practice to have multiple dataproviders initialsed at startup which the user can switch between as they click each category rather than modifying the same dataprovider? Basically I'm just wondering what way would you guys do it? I thought using just one dataprovider would slim down the code and make the app faster and more reliable but now I'm not sure.

I know this is very late in the game, and I haven’t read the full thread, but
this seems like a very complicated solution to the problem. Further, the

If you have a string that looks like a number, it will get converted to a

Using e4x and looping over the categories.category XMLList is very simple.
XMLLists are never null, but empty nodes just result in a zero length, which is

Hi Robert. Thanks so much for that my friend.
I have some problems with it though. You see I have an event in my app

i.e. LinksService. send and I've noticed that with your code if there is only
1 link i.e. 1 node and I click the refresh button it seems to keep recreating
that 1 over and over again as if it's recreating the same object in the array
collection or something. This doesn't happen if their are 2 or more
links/nodes/ objects. Perhaps I'll have to get the refresh button to empty
the array collection first before sending the data i.e. it's click function
would be LinksFullAC. flush; LinksService. send() Am I right?
I've also noticed now with your code applied if I select an item in the
tilelist and click the reresh button I get the error Property categories not
found on String and there is no default value which is indicating the error

idea what's causing this?
Another question though what if the xml contains no nodes?
You see my xml file is dynamic, I have a variable in my app called categoryid
and that variable is based on a category that the user selects in my app and
is submitted to getlinks.php which gets all the records from my mysql table
which contain that specific submitted categoryid and output them as the xml

via my app). Is there any way of getting it to handle 0 records/nodes as well
as handling muliple records/1record which it seems to already do?

RE: [flexcoders] Tilelist Populated by Remote XML Only showing Data from files with 1 Node
I suspect you have left the resultFormat at its default object. This has Flex parse the xml into a tree of dynamic objects. It turns xml lists into arrays, and because the player cannot differentiate between an array with one element and an object, you have this known issue. I suggest setting resultFormat=e4x and processing the resulting xml as needed for your dataProvider. You can use the xml directly, or use an XMLListCollection, or convert the data into an ArrayCollection of stronglyTyped value objects. There are other solutions, including inspecting the result object to determine what it contains. You can also use the toArray() function.

RE: [flexcoders] Re: Loading swf in child window?
If I am understanding correctly you will want to use SWFLoader. It allows you to load pretty much any swf. Normally the swf's must be compiled with the same version of AS, because if the two swfs run in different virtual machines, they will only be able to communicate via LocalConnection. You typically use SWFLoader when the swf you want to load is a complete application. those are big, because they include so much of the framework. If your swf is not a full application, you can use modules. The primary value of both is that the loaded thing does not need to be compiled into the loading app. I have loaded applications into applications very often, with several apps in production for years and it works extremely well. All those apps were intranet apps on fast, wired networks, so swf size was not a critical constraint. Communication with the loaded swf is simple via a reference to the .content property. However, there are some timing issues to handle, because the complete event of the swf loader does not mean that the application being loaded is also complete. Here is a sample application that demonstrates this communicatin setup: http://www.cflex.net/showFileDetails.cfm?ObjectID=690 Tracy Spratt, Lariat Services, development services available _ From: flexcoders@yahoogroups.com [mailto:flexcod...@yahoogroups.com] On Behalf Of newflexer Sent: Wednesday, March 24, 2010 10:38 AM To: flexcoders@yahoogroups.com Subject: [flexcoders] Re: Loading swf in child window?

This is because E4X-specific opcodes act like with() construction, i.e. they just push the current XML node context in front of every other context in the context lookup chain. While XML class is dynamic, it is OK to try to access a non-existent property on it, however, the context lookup behavior verifies for the property existence, and if the property doesn't exist, it advances to the next link in the chain - to function arguments - function local variables - class fields - open namespaces - global context. Global context is not dynamic, and it is difficult to believe that some of the scopes will happen to be a Proxy subclass which implements getProperty() + isAttribute(). So, the error you are talking about is caused by that while resolving scope the VM will hit an instance of the sealed class object, which will cause it to throw NPE. But, if you limit the scope lookup to only the context of XML node - that is by calling it on valueOf(), you will not traverse the scopes chain - thus no NPE, you'll get empty-string, which is the default XMLList behavior for converting a null-XMLList. So, it is safe to do: foo/.(trace( valueOf()@bar ) ); but it is not safe to do: foo/.(trace( @bar ) ); Best. Oleg

If you can see the xml when you do:

trace(myXML.toXMLString()); //do yo see the whole xml?
then go one level deeper:
myXML = myXML.data[0]
trace(myXML.toXMLString()); //do you see the data xml
If so, go one level deeper, and trace that, etc.

RE: [flexcoders] Re: I need some basic ActionScript help that I'm stumped on
There is some data type confusion going on here. If you are using the xml
as the data source, how are you getting it into Flex? I strongly suspect you
are letting Flex do its default resultFormat conversion into a tree of
dynamic objects. Actionscript can't tell the difference between an Object
and an Array with a single element so it opts for object. You can't get the
length of an object.
This, selectedItem.links.link is object tree syntax, not XML or
ArrayCollection syntax.
There are several solutions. I advise using resultFormat=e4x, then
processing that xml into an ArrayCollection of strongly typed value objects.

RE: [flexcoders] Re: HTTPService not returning ArrayCollection...
This is an issue when you use the default resultFormat=object. This
causes Flex to convert your xml into a tree of dynamic objects. There can
be problems with this conversion. The problem you posted is one. Another
is that if you have strings that look like numbers, they will get converted
to numbers. Also, dynamic objects are slower than strongly typed objects,
which might be an issue for a complex data grid. There might be other
problems as well. If any of these become a problem, I'd advise using
resultFormat=e4x, then processing that xml into an Array Collection of
strongly typed VOs.
And to clarify, with the default resultFormat conversion, you are getting
Array, not ArrayCollection. Note Steve's code.

This works great when I have more than one object in the XML file. But

Let me give an example:
MyXMLFile.xml:
people
person

lastNameSmith/lastName

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

No, you don't want to do that. You must have your renderer's checkbox state

is changed, change the value in the dataProvider item. To programmatically
change the state of the checkbox, get a reference to the dataProvider item,

You cannot directly access a control in a renderer because they are

Subject: [flexcoders] Accessing checkbox inside a Datagrid ItemRenderer
Hi FlexCoders,
Having some troubles trying to resolve this. I hope someone can give me
guidelines on how I would be able to achieve this.
I need to reference a checkbox inside the datagrid. Below please find some
codes I have used.
mx:DataGrid id=dgCurrentTasks width=100% height=100%
dataProvider={xmllcCurrentTasks} horizontalScrollPolicy=on
verticalScrollPolicy=on
click=dgCurrentTasks_Click(event)
mx:columns
mx:DataGridColumn headerText=Task ID width=70 dataField=TaskID/
mx:DataGridColumn headerText=System width=100
dataField=SystemDescription/
mx:DataGridColumn headerText=Task Description width=300
dataField=TaskDescription/
mx:DataGridColumn headerText=Complete width=30 textAlign=center
mx:itemRenderer
mx:Component
mx:VBox horizontalAlign=center verticalAlign=middle
mx:CheckBox id=cbxComplete
click=outerDocument.cbxComplete_Click(event, data.TaskID,
data.SystemDescription)/
/mx:VBox
/mx:Component
/mx:itemRenderer
/mx:DataGridColumn
/mx:columns
/mx:DataGrid
And the function called by the checkbox inside the datagrid.
public function cbxComplete_Click(e:Event, issueID:String,
systemDescription:String) :void
{
if(e.currentTarget.selected)
{
Alert.show('Are you sure you want to set Task ID ' + taskID + ' to
Complete?',
'Task Complete Confirmation', Alert.YES | Alert.NO, null,
completeTaskAlertHandler, null, Alert.NO);
}
}
And the alert handler
private function completeTaskAlertHandler(evt:CloseEvent)
{
if (evt.detail == Alert.YES)
{
// Do the TASK COMPLETION Here.
Alert.show('Setting Task Status to COMPLETE', 'TEST ALERT');
}
else
{
// Uncheck the checkbox which was checked.
Alert.show('NO??', dgCurrentTasks.selectedIndices.toString());
//dgCurrentTasks.selectedIndices.cbxComplete.selected = false; --- This
does not work...
// I need to reference the checkbox here so that I could UN-Select it.
}
}
Another question, would it be possible that instead of declaring the
function completeTaskAlertHandler, is it possible to simply place it inline
inside the cbxComplete_Click function? Like:
public function cbxComplete_Click(e:Event, issueID:String,
systemDescription:String) :void
{
if(e.currentTarget.selected)
{
Alert.show('Are you sure you want to set Task ID ' + taskID + ' to
Complete?',
'Task Complete Confirmation', Alert.YES | Alert.NO, null,

RE: [flexcoders] advanced datagrid in popped up titlewindow issue
Probably a timing issue. Binding is difficult to debug. Make sure your
dataSource var is bindable. Initialize might be too early. Test the content
in a handler function and also check it in a creationComplete handler. I
rarely use initialize for any data oriented work.

Nevermind...figures it out. I am a moron. Just extended the LinkButton

own to change the stack order, and used the e.target.index (index being
my own custom variable) and it works fine.

Ok, I am requesting the collection brain power to get over this mental
hump of how to add dynamic buttons and have them control a view stack of
modules.
I have 4 different portals for kids, siblings, parents, and hospitals.
When the user logs in, it finds their type and loads an XML document
containing module file names and button names. Each portal contains
different number of modules and depending on the XML document, that can
change.
Right now I am looping through the XML and creating LinkButtons with the
name node being added as the label. Problem is that I want to then
load the modules in a viewstack and use the buttons to switch through
the stack using the index of the loop to tell the button what
selectedIndex of the stack to show. (I.E. the first loop, i = 0, so the
MouseClick eventlistener will set the viewstack's selectedIndex to 0
(the first level). I want the module to match up with the button. Hope
that makes sense
Anyways I am adding an embedded function to the MouseClick eventlistener
I am associating with each LinkButton before I addChild() it to the
application. Problem is, the index I am associating with it is wrong
when I attempt to trace it.
Ok, all that to show you this and hope you can help me. What I want is
to loop through the XML document, create LinkButtons with the label from
thename node and then, when clicked, change the ViewStack (appVS) to
the index that matches the current loop. I am up for both modifying my
code (or pointing out what is wrong) or a better idea.
public function init():void {
for (var i:int = 0; i moduleList.module.length();
i++){
var button:LinkButton = new LinkButton;
button.label = moduleList.module[i].name;
button.setStyle(fontSize,12);
button.addEventListener(MouseEvent.CLICK,
function():void{appVS.selectedIndex=i;});
navACB.addChildAt(button, i);
}
}
The first button should be created, put in the 0 space on the navACB,
and move the ViewStack to the 0 level when clicked.
Next should be created, put it in the 1 space on the navACB, then move
the ViewStack to the 1 level when clicked...and so on.
Thanks!

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?

RE: [SPAM] [flexcoders] Obtaining rendered text from a DataGrid
I will answer, but you probably won't like the answer.
This is simply not possible. In order to optimize performance, DataGrid and
the other list components only create(render) the visible elements. If a
row is not visible, it does not exist. You can't look sideways into your tv
screen and see beyond the edges.
You must do wok like this using the dataProvider.
What are you trying to do?

RE: [SPAM] [flexcoders] Re: Custom ItemRenderer still not working...
Refresh() is intended to re-apply a sort of filter to a collection. If it
is working in your case it is a side effect.
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?
I have an example on cflex. It is more complex than necessary because I
wanted it to be generic:

Well, I found a work-around...
I added the following code inside my ComboBox ItemRenderer:

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.

But instead the second tab header is shown as selected but the content is of first tab. I have attached sample example for reference. Please suggest what do I need to do to fix the problem.

then, I pass that into the Flex app using flashvars:

flashvars, _sPassedUrlParms,

Then I access those flashvar values in Flex using
application.application.parameters object, which will have a property:value
for each passed in url param.
You can also use ExternalInterface to get the URL information instead of
using the javascript, google for examples of that. I found this component
that seems to encapsulate that functionality:

Subject: [SPAM] [flexcoders] Reading URL arguments from within initApp()
I'm working on a registration system that will be used by new and
existing participants. The customer would like to be able to email
existing participants a URL that bypasses the login screen. So, if the
usual URL is
http://www.foo. http://www.foo.com/register.html com/register.html
They would like to use a URL that skips the landing screen and goes
right to the registration details (name, address, etc.):
http://www.foo. http://www.foo.com/register.html?user=bobpassword=pluto
com/register.html?user=bobpassword=pluto
(Those aren't the exact arguments but should illustrate the point.)
I've been hunting around but haven't sorted out where to find the
correct properties. If I can read in the URL, I can pass the data to
my existing login function and carry on from there. If there's a more
standard/best-practice way of starting the app with URL arguments, I'm

RE: [SPAM] Re: [SPAM] [flexcoders] TabNavigator switches to second tab when revealed after a currentState change
A ViewStack is simply a way to switch between components. It has no visible presence of its own. The children of a ViewStack can be anything (in some container), including a full TabNavigator. You can nest ViewStacks as desired. A side note on TavNavigator; if you think you will ever want to dynamically control the visible tabs, say based on user identity/permissions, I advise TabBar + ViewStack. To remove hide a tab in a TabNavigator, you have to manipulate the childen directly. If you use a TabBar, you can control its content just by manipulating its dataProvider. A hidden view will still be in the ViewStack, but its tab will not be visible, thus the view will be unavailable.

The base state for this application is a TabNavigator with three Canvas subelements. On its own, this works fine. When the application loads, I switch away from the base state to a screen to let the user login/get their password emailed/add a new registration. If they want to add a new registration, currentState is set back to to return to the base state - the full data entry form. The funny part is that when the state changes, the selectedIndex of the TabNavigator switches from 0 to 1. I've stepped through in the debugger and before this line the (hidden) TabNavigator has an index of 0. this.currentState = ; // Base state has input form After this line, the TabNavigator has an index of 1. If I explicitly reset the selectedIndex back to 0, the TabNavigator is drawn with elements from the first two pages drawn on top of each other. I can see that the Canvas for index 0 is drawn and the Canvas for index 1 is drawn on top of that. I've tried using a ViewStack instead of TabNavigator but, as you would expect, it makes no difference. I've been going around in circles for some time here without any progress - is this problem ringing a bell? I didn't find anything like it in the archives. I've tried with the 3.2 and 3.5 SDKs but the behavior is the same in both cases. I could skip the TabNavigator completely and do everything with ViewStates but, honestly, I'd rather not.

RE: [SPAM] Re: [SPAM] [flexcoders] e4x to Datagrid not removing the tags when rendered
Yes. I think that will give the automatic column generation functionality a
problem.
I think you should manually loop over the repeat nodes, and for each,
populate a value object with strongly typed properties assigned the values
from the appropriate feature and value nodes. Your code to make the
assignment will have to use the positional syntax instead of e4x filters.
For example in psuedocode:
Var voRepeat: RepeatVO;
For each(var xmlItem:XML in root.repeat) {
voRepeat = new RepeatVO();
voRepeat.featue1 = xmlItem.feature[0].text();
voRepeat.featue2 = xmlItem.feature[1].text();
voRepeat.value1 = xmlItem.value[0].text();
.
myArrayCollection.addItem(voRepeat)
}
MydataGrid.dataProvider = myArrayCollection;

If you dataProvider is valid, you might have just forgotten to specify the

If you are setting that property, then you need to know that dataField can

RE: [SPAM] [flexcoders] How long does it take to learn Flex and get a job?
That question has no answer. When will you know that have you learned Flex? I am not sure I have learned Flex and I have been writing production applications for seven years. You say 1 year, but how many hours a day? If you write Flex apps for forty hours a week for a year, then I would be confident you could qualify for an entry level (whatever that is) position. If you spend four hours a week, I would not be so confident. And there is much more to software development than just coding. But still, go for it. Don't wait until you have learned Flex. Once you get the basics of the language, start trying to find a job. The pressures of deliverables, deadlines, designer/client negotiation and solving business problems are what will really make you learn a language.

RE: [SPAM] [flexcoders] e4x to Datagrid not removing the tags when rendered
First, the DataGrid dataProvider itself must be some kind of list. It can be an ArrayCollection, an XMLListCollection, an Array or XMLList(avoid these if you plan to programmatically update the dataProvider) There are two ways to get an HTTPService result into a dataProvider. One is to bind to lastResult.avoid this. Instead, use a resultHandler to assign the appropriate list type to a variable, and bind to that. If you dataProvider is valid, you might have just forgotten to specify the dataField for the columns. If you are setting that property, then you need to know that dataField can only handle a string, not an expression, and the property specified must be a top-level property of the dataProvider item. If the dataProvider items are XML nodes, the datafield must specify a first-level childNode(data in the text node of that node) or an attribute. If it is an attribute then you need to use the @ symbol. Example: dataField=@myAttribute. Hope this helps.

RE: [SPAM] [flexcoders] What server do I put my crossdomain.xml file on?
I am fairly certain that it will need to go on the server that is hosting the servlet, since that is the only domain that the FlashPlayer is going to know about.

Jeff,
Thanks for the reply. I am confused by the behavior of my Flex app. The
status bar says Transferring data from localhost... and that status
message never goes away. But, as you suggested, the data are complete: I
pop the raw JSON string returned by the webservice into a TextArea, and it's
all there, a string literal representing an array of objects:
[{...},{...},{...}], and the string literal decodes into a well-formed
ActionScript array.
Is there something my results-handler has to do to clear that status
message?
Tim
Maybe I'm missing something here, but to my understanding when the result
event of your HTTP service fires, your call IS complete. You should have
access to the json string that was pulled back from the service. Is there
something else you need that the json string doesn't' supply?

I'm not sure how proper a solution that would be -- there are a lot more
html entities than just those and I don't think writing a replace for each
character makes much sense.
I was initially under the impression that if I used the htmlText property, a
string like something amp; something would auto-magically be converted to
something something. If this isn't the case, is there a property or
component in Flex which I'm overlooking that would automatically take care
of this?
I suppose the main problem is with the text example I presented: This is an
item This is another item In a breadcrumb trail. I suppose using
htmlText would not work because the '' characters would be taken as closing
tags? Maybe I can just write a function to replace '' and ''. (?)
Do you or any others have other suggestions or comments on what a good
approach would be?

You can manually convert the data yourself. Regular expressions are
probably a better way to go, but I do not use them enough to be
comfortable
with them, and use a function like this:
public static function htmlDecode(s:String):String
{
s=s.split(amp;).join();
s=s.split(quot;).join(\);
s=s.split(apos;).join(');
s=s.split(/lt;).join(/);
s=s.split(lt;).join();
s=s.split(/gt;).join(/);
s=s.split(gt;).join();
return s;
}
The replace() function might be better as well.

Hello everyone,
I've recently come across a problem at work where in much of the data
we're
getting is showing up in the data-grid as:
bThe tags showb and the quot; quotes quot; aren't converted!
This is a problem and I'd like to be able to display this correctly:
The tags show and the quotes aren't converted!
We don't necessarily have too much control over the data, so I'm not
entirely sure how/why the items are coming up like this when some items
come
up with characters like in them. For instance: This is an item This
is another item In a breadcrumb trail. This shows up correctly. I'm not
sure what exactly should be done. But again since we don't have
control/access to the data, it cannot be changed or substituted or
converted
to other formats. I thought of using htmlText but that doesn't work if I
have data like the breadcrumb string above because it interprets the ''
characters as opening tags and doesn't render the entire data:
[Bindable]
private var testString:String = lt;bgt;6lt;bgt; quot;sevenquot;;
mx:Text text={testString} / !-- displays testString unchanged --
mx:Text htmlText={testString} / !-- displays: b6/b --
Any suggestions would definitely be appreciated, I'm sure I'm probably not
the only person that's come across this :( But basically we just need all
characters like: lt; to be converted to '' and amp; to be '' meanwhile
data that was encoded properly, data that has '' and '' showing up
correctly should be left the same.
Thanks in advance for any help :)

RE: [SPAM] [flexcoders] Single Record Tables
The best way is to set resultFormat=e4x. The default resultFormat
(object) causes Flex to convert the xml into a tree of nested objects. In
this case, if there are multiple sub nodes, Flex knows to create an array,
but if there is only one node, it just has to create a single object.
You can test result using, if I recall correctly, if (result is Array).
But best practice is to use e4x and then build your ArrayCollection of own
strongly typed VOs.

I have a table with a single record in it and I've been trying to read it

which seemed to work but has stopped working for some unknown reason. This
is my latest attempt to load an ArrayCollection.
Anybody got any suggestions?

RE: [SPAM] [flexcoders] HTTPService Internet Explorer
This is almost certainly a caching issue. If you are using GET as the HTTPService method try POST. Then if that does not work, you can append some random string to the url to prevent client side caching. There will be many code examples if you search for them.
