[flexcoders] Flex Charting chart updated event?

[Maciek]

I need to update some UI elements when a chart receives new data from
its data provider and is done updating (specifically, it updates the new
minimums and maximums for its axes). I've looked at the Flex Charting
events, and I don't see anything like this. Anyone know of related
events I could listen for?

Thanks,

Re: [flexcoders] mxml loader

[Maciek]

I don't think this is possible, since MXML is actually compiled down to
ActionScript. I believe the closest you can come to this is have a web
service that will invoke the compiler and build mini-swfs (same mxml
that you were thinking of sending around, plus just enough skeleton code
to get it to compile), then send you the actual swfs. Then you can load
the swfs. This might not give you the performance you'd like, though...

Re: [flexcoders] Re: application exit event?

[Maciek]

Unfortunately, we can't help but litter in this situation: we open a
URLStream connection, and Flash Player (in Internet Explorer) does not
drop the connection when the corresponding URLStream object is destroyed
(I assume that it probably would drop the connection when GCing). This
is a Comet-style connection that must remain open while the Flex
application is running, so it's not something we can clean up "when
we're done" without having access to an application exit event. The user
killing the browser at any moment is not a problem for us, because in
that case, the connection is dropped properly.

I'll try Sherif's Javascript suggestion, although I was hoping there
would be something cleaner.

RE: [flexcoders] Re: What is the best way to compare two arrays element by element ignoring the o

[Maciek]

True. However, andrii's solution does amortize the cost of the
comparison across all array modifications, so you don't incur it all at
once when doing the comparison. Depending on the actual requirements of
the situation (and assuming you control array modifications, and are not
just trying to compare two arrays you've been handed out of the blue),
this may be a useful trick.

Indeed. Granite Data Services includes gas3 in recent versions, which
does exactly what you want. We've used it at Truviso on a small set of

[flexcoders] flex 2/3 charting questions

[Maciek]

We need to build a Flex 2 project that uses Flex Charting. Is it
possible to download Flex Charting 2? All Adobe Flex Charting 2 links
seem to point to FlexBuilder 3. I know that FlexBuilder 3 includes the
Flex 2 SDK: with the pro version (that includes Flex 3 Charting), is it
possible to build a project with the Flex 2 SDK but using Flex 3
Charting? We're not ready to update the project to Flex 3 yet (we hope
to do this very soon, but not immediately). Has anyone ran into similar
issues before? I know that boxed versions of FlexBuilder 2 are available
from places like Amazon, but this is really sort of a one-time
build--the watermarks are not important and shortly afterwards we're
planning to move to Flex 3.

Any advice would be greatly appreciated.

No, it's a separate file. It used to be available from Adobe, but is not
any longer: there are still Flex 2 Charting links on Adobe's web site,

There are five days remaining on my FlexBuilder alpha 2 trial. From what

[flexcoders] layout question

[Maciek]

Hi. I've been doing a fair amount of Actionscript, and am now getting to
do some mxml layout. I

I have a component with a login control (this is the only child in the
component, and the parent is a VBox with width and height set to 100%):














This does what I expect for the form, (it has a margin of 10px), but the
button is clinging to the bottom left of the panel. I think I'm missing
something. Any suggestions?

Re: [flexcoders] JAXB for actionscript

[Maciek]

I'm not aware of anything, but you could try JAXB for XSD -> Java, and
then something like Granite Data Services' gas3 to go from Java ->
ActionScript. We've recently done someting similar (although, granted,
we actually wanted the Java code as well), and it worked reasonably
well...

You can place them on

then in as:

[flexcoders] LCDS AMF call not firing result events, busy cursor does not go away

[Maciek Sakrejda]

I'm running into some odd Flex behavior, and I was wondering if anyone
had run into something similar before. Basically, it looks like my
RemoteObject result handlers are sometimes not being called. More
specifically, I have a remote object that corresponds to a Java class
which makes a jdbc call and returns some data. This remote object call
is invoked from a button and adds a new tab to a dashboard. The new tab
renders the results.

Most of the time, this works fine, but occasionally, the AMF call never
fires the handler (neither success nor failure), and the busy cursor
never goes away. I've double-checked to make sure that I register result
handlers before I invoke the method. The flashlog.txt file does not show
anything odd. A Java thread dump on the server does not show any
outstanding AMF calls being serviced, and if I re-try the same action,
it works fine (although the original tab still never gets any data). The
busy cursor remains until I close the client Flash object, but other
than that, the client behaves normally. I've verified that the event
listeners are being added before the remote call is made, but it almost
seems like a bigger issue: the busy cursor should go away as soon as the
result event is fired, whether I registered for it or not, right?

For what it's worth, I seem to hit this more frequently if I open a
burst of new tabs quickly one after another.

I'm using:
Java HotSpot(TM) Server VM (1.5.0_14-b03 mixed mode)
Adobe Flash Player 9,0,115,0 (debug)
Apache Tomcat 5.5.23
LCDS 2.5.1

Hmm... I'm not sure if me pulling suggestions out of thin air is at all
helpful, but have you tried labelFunction and parseFunction? I don't see
why the default wouldn't work, but if there's a problem, you could use
these two to hack up a fix for your specific format (assuming you have a
specific format, and are not trying to parse dates with arbitrary format
strings).

Re: [flexcoders] Dash symbol on xml tag

[Maciek Sakrejda]

Assuming you have a variable called styles that references this file,
you can use

styles.style.["font-family"]

to access the XMLList with the single element font-family, or

styles.style.["font-family"][0]

to access the actual font-family element itself.

Re: [flexcoders] LCDS AMF call not firing result events, busy cursor does not go away

[Maciek Sakrejda]

Ok, I suppose there may be no answer since this is not exactly a minimal
test case. Let me simplify the question:

Under what circumstances would a RemoteObject AMF call not restore the
cursor from the 'busy' state?

Relevant source:
override public function init():void {
// create service
_remote = new RemoteObject();
_remote.showBusyCursor = true;
_remote.destination = "fooService";
_remote.addEventListener("result", handleResultReceived);
_remote.addEventListener("fault", handleFault);

var params:Object = new Object();
for each (var f:Filter in _filterCollection.filters) {
if (f.isServerFilter) {
f.refreshValue();
params[f.field] = f.value;
}
}

_remote.executeStaticQuery(super._queryId, params,
super._serverTransformer);
 }

Again, this error is not consistently reproducible: it works most of the
time, but occasionally, the busy cursor never goes away, and neither the
result handler nor the fault handler get invoked.

I can understand that the handlers not getting invoked could be
something that I'm doing wrong, but why would the busy cursor stay? Any
suggestions?

RE: [flexcoders] LCDS AMF call not firing result events, busycursor does not go away

[Maciek Sakrejda]

Thanks a lot, Seth. Given that most of the time, this does work
correctly, it's most likely a network issue (for one reason or another),
right? Or can you think of other possible causes?

busycursor does not go away
Date: Mon, 14 Jan 2008 14:58:27 -0800

The busy cursor is set when a RemoteObject operation is invoked using
CursorManager.setBusyCursor(). It's removed when a result or fault for
the invocation is returned, via a call to
CursorManager.removeBusyCursor().

If you're not receiving a result or fault event, that would explain why
the busy cursor is not being unset.

RemoteObject, and the other RPC-related client components, define a
'requestTimeout' property that represents the number of seconds the
RemoteObject will wait for a response or fault from the server/network
before giving up and just faulting the call locally on the client. You
may want to enable this property, in order to abort requests that are
lost in the network (although this sort of failure should be very
intermittent and if it's common you should do more debugging or your
network to attempt to determine why the requests are dropping).

Best,
Seth

Ok, I suppose there may be no answer since this is not exactly a minimal
test case. Let me simplify the question:

Under what circumstances would a RemoteObject AMF call not restore the
cursor from the 'busy' state?

Relevant source:
override public function init():void {
// create service
_remote = new RemoteObject();
_remote.showBusyCursor = true;
_remote.destination = "fooService";
_remote.addEventListener("result", handleResultReceived);
_remote.addEventListener("fault", handleFault);

var params:Object = new Object(); 
for each (var f:Filter in _filterCollection.filters) {
if (f.isServerFilter) {
f.refreshValue();
params[f.field] = f.value;
}
}

_remote.executeStaticQuery(super._queryId, params,
super._serverTransformer);
}

Again, this error is not consistently reproducible: it works most of the
time, but occasionally, the busy cursor never goes away, and neither the
result handler nor the fault handler get invoked.

I can understand that the handlers not getting invoked could be
something that I'm doing wrong, but why would the busy cursor stay? Any
suggestions?

Subject: [flexcoders] LCDS AMF call not firing result events, busy
cursor does not go away
Date: Fri, 11 Jan 2008 10:52:53 -0800

I'm running into some odd Flex behavior, and I was wondering if anyone
had run into something similar before. Basically, it looks like my
RemoteObject result handlers are sometimes not being called. More
specifically, I have a remote object that corresponds to a Java class
which makes a jdbc call and returns some data. This remote object call
is invoked from a button and adds a new tab to a dashboard. The new tab
renders the results.

Most of the time, this works fine, but occasionally, the AMF call never
fires the handler (neither success nor failure), and the busy cursor
never goes away. I've double-checked to make sure that I register result
handlers before I invoke the method. The flashlog.txt file does not show
anything odd. A Java thread dump on the server does not show any
outstanding AMF calls being serviced, and if I re-try the same action,
it works fine (although the original tab still never gets any data). The
busy cursor remains until I close the client Flash object, but other
than that, the client behaves normally. I've verified that the event
listeners are being added before the remote call is made, but it almost
seems like a bigger issue: the busy cursor should go away as soon as the
result event is fired, whether I registered for it or not, right?

For what it's worth, I seem to hit this more frequently if I open a
burst of new tabs quickly one after another.

I'm using:
Java HotSpot(TM) Server VM (1.5.0_14-b03 mixed mode)
Adobe Flash Player 9,0,115,0 (debug)
Apache Tomcat 5.5.23
LCDS 2.5.1

Any thoughts?

Re: [flexcoders] Trouble with try/catch for loader error

[Maciek Sakrejda]

Ben,

Try registering with loader.contentLoaderInfo for the various load
events (especially IOErrorEvent.IO_ERROR) to see what could be going
wrong. Since the load is asynchronous, Flash may not be able to throw an
error immediately, so it has to dispatch an error event.

Re: [flexcoders] Flex Charting chart updated event?

I've looked into binding to the value of DateTimeAxis.maximum and

Hello,
  I got it to work.  I had to change the e4x expression a little to get
it to work.  I needed to qualify the ID with the namespace.  So this
code works:


var xml:XML = new XML(inputXML.text);
var ns:Namespace = xml.namespace();
trace(xml.namespace());
var filterdXML:XMLList = new XMLList(xml..ns::folder.(ns::id ==
13));
outputXML.text = filterdXML.toXMLString();

Notice the ns:id == 13.

So, now that I got it working, I'd still like to get it working with the
following syntax so I dont have to add namespace aliases to my e4x:
private namespace ns="http://";
use namespace ns
Thanks for any suggestions on taking this further.

Hi Kevin,

I've gotten flare to work in our Flex-based app. I'm still just
experimenting with it, but it works quite well. The main trick is to add
a Visualization instace to a UIComponent, and then add that UIComponent
to your Flex application (you can't add Visualization directly as a
child because it doesn't implement IUIComponent. I believe Jeff plans to
add (some) more Flex support, but looking at svn, he's focusing on the
data package right now.

Re: [flexcoders] flex profiling

[Maciek Sakrejda]

This sounds normal, yes. Some more memory will be used for each new
DisplayObject (each new Object of any kind, for that matter). It won't
be reclaimed until all the references to that object are gone, and the
GC sees fit to do a collection. It could be that you have stranded event
listeners or something somewhere causing a leak, but it's also likely to
be just normal behavior. If you want to find out for sure, read up on
Flash Player's memory management (e.g., here:
http://blogs.adobe.com/aharui/2007/03/garbage_collection_and_memory.html ).

We use the standard Flex/Java structure of a package/directory tree

It's a little deeply nested, but that's a minor inconvenience. It works

columns based on the size of its children and its parent, rather than
always trying to make a 
square.

Has anyone implemented something like this?

Unfortunately, your only other option is magic. Well, technically, you
could reimplement a subset of RTMP by having User2 make a URLStream
request to the server, have the server keep the connection open and push
data as it gets changes from User1, and retrieve this on User2's machine
by listening to ProgressEvent.PROGRESS events fired by the stream as
data comes in. This is no small undertaking, though, and runs into a
couple of ugly issues.

How I can make a auto refresh of data when this data is modified without

Really what I need to be able to do is insert the variable name in this:

I need to replace the "month" with a string variable name (i.e public
var monthName = "January";)

I also need to do the same for the categoryfield as it will not let me
do categoryfield=$String.

In PHP this is incredibly easy to do. You just say blah=$string . In

powerful. For instance, in php, for the dataprovider issue above, i'd
just do

dataProvider="{chartXML2.lastResult.$StringName.day}"

and it'd work just fine. Whats the syntax for doing this in Flex? 




 

Re: RES: [flexcoders]

[Maciek Sakrejda]

Right, I believe that's not implemented. Alternately, you could take a
look at Granite Data Services, which just released 1.0 and does provide
a data push implementation, although I haven't used it and I  don't know
how compatible this is with RTMP. We are using GDS for AMF at Truviso,

Subject: [flexcoders] Differences between MXML and ActionScript in
setting event listeners?
Date: Wed, 06 Feb 2008 16:51:05 -

I have a custom component (PlotControls.mxml). It inherits from
DisplayObject (via HBox), so my understanding is that it will support
event bubbling.

In it I have defined a 'viewChanged' event:


[Event(name="VIEW_CHANGED", type="flash.events.Event")]


public static const VIEW_CHANGED:String = "viewChanged";

In that component I also have some AS code which broadcasts that event
(notice that bubbling is TRUE):

private function viewSelectedHandler():void
{
dispatchEvent(new Event(PlotControls.VIEW_CHANGED, true));
}

-
Next, I have a parent component, which also inherits from
DisplayObject via HBox. In the parent component, I have created an
instance of the first (child) component:



I also have some initializer code in the parent component which adds
an event handler to the child component:

private function initComponent():void
{
plotControls.addEventListener(PlotControls.VIEW_CHANGED,
viewSelectedHandler);
}

And the handler code looks like this:

private function viewSelectedHandler(e:Event):void
{
var plotId:String = plotControls.getPlotId();
Alert.show('viewSelectedHandler(); plotId: '+plotId);
}

All of the code ABOVE works as expected: when the UI in the child
component dispatches the event, the parent component's event handler
is getting called.

-
On the other hand, I tried setting the event listener directly on the
child component itself via the MXML markup (and removed the
addListener call from the parent's initializer):



Note: the Flex Builder IDE is showing me 'code completion' information
for the VIEW_CHANGED event, so I think that I have the right syntax
here, at least.

BUT THIS DOESN'T WORK! (The event handler is never invoked.)

*** My Question: why does the event handler, viewSelectedHandler(),
for the VIEW_CHANGED event NEVER get called when I add the listener
directly via the MXML markup? My understanding of Flex is that these
two approaches should yield the same results (though using
addListener() gives you more options.

What am I overlooking here--this one has me stumped. Could someone
please give me a clue?

Thanks in advance,
Jim

As of now, it is not possible to declare a constructor private (other
than public) in ActionScript 3.0. However, as pointed out, it is
possible to achieve the required behavior by using a dummy private
class defined outside the package so that no one has access to it
outside the file. Passing a dummy instance of this class to the
constructor of the singleton class should prevent other users from
instantiating the singleton class. Here is a code snippet illustrating
the concept:

package
{
class Singleton
{
private static var theOneAndOnlyInstance:Singleton;

public function Singleton(dummy:DummyPrivateClass)
{
super();
}

public static function getInstance():Singleton
{
if(theOneAndOnlyInstance == null)
{
theOneAndOnlyInstance = new Singleton(new DummyPrivateClass());
}
return theOneAndOnlyInstance;
}
}
}

class DummyPrivateClass
{
public function DummyPrivateClass() { super(); }
}

I'm doing a charting application that allows the user multiple ways to

line of business organizational perspective).
 
My current problem is that when I drill down from the main (i.e. year
level view) component, say to a month component,  how do I get back the
main component.  I can move around within 1 component (applying
different chart types to the same set of data) using includeinlayout and
visible.
 
In fact, to get to a sublevel component I just turn off the other
components and make that one (includeinlayout and visible).  But now
control has passed to the sub-component and I dont know how to get back.
You cant turn off the component that you are currently in can you?  I
tried states but I find the includelayout and visible a lot more
straightforward to work with.  But I guess I can go back to states if
that is what is required here.

Re: [flexcoders] Help with RegEx

Unfortunately, you've hit an ugly problem for regex, Marty. Check out
the section on "Difficulties and Impossibilities" from "Mastering
Regular Expressions" at
http://www.oreilly.com/catalog/regex/chapter/ch04.html

"In fact, the problem is that you simply can't match arbitrarily nested
constructs with regular expressions. It just can't be done.

You can construct a regular expression that matches nested constructs up
to a certain depth, but not to any arbitrary level of nesting. A regular
expression to allow just one level of nesting is the monstrosity
\([^()]*(\([^()]*\)[^()]*)*\)..., so the thought of having to worry
about further levels of nesting is frightening. Sometimes, you just have
to use other, non-regex methods."

Given the delimeters oof { and }, I want to be able to return:

As well as

Which works fine without nesting. As soon as you introduce nested

Re: [flexcoders] Supporting both double and single click events for TileList

[Maciek Sakrejda]

Right. If a double-click occurs, you'll get the single-click behavior as
well. What you want to do is add a listener for the single click that
starts a timer for a function that will execute the single-click
behavior in n milliseconds. If a second click occurs, cancel the timer.
The double-click event handler will be invoked normally. I've seen
examples around, but a quick search did not turn up what I was thinking
of. I'm sure you can find a relevant example with a little
investigation.

Note that this (necessarily) introduces a slight delay for the
single-click behavior. As long as you keep this under 300-500 ms, it
should be barely noticeable for your application.

Hi All,

 

I have a photo gallery on my site (TileList of thumbnails) and I am
having problems with double click events when employing click event.  I
would like to support the events as follows:

 

- ItemClick, open image popup window with image slightly larger
than thumbnail

- ItemDoubleClick, open image popup window with large view say
800x600

 

The ItemClick event happens before the double click and it displays a
popup over the selected item. It seems impossible to catch the double
click the way I am trying to implement it using both (itemClick and
itemDoubleClick events). It feels like I need to catch a generic
‘change’ event, inspect how many mouse clicks occurred and proceed
accordingly. 

 

Is this possible? 

 

Thanks,

[flexcoders] flex 2 charts: multiple axes

[Maciek Sakrejda]

I'm trying to figure out the behavior of Flex 2 charts with multiple
axes. I've read this in the docs:

By default, all charts that are subclasses of CartesianChart
display a single set of data, and single horizontal and vertical
axes. Setting any of the secondary properties, such as
secondDataProvider, secondSeries,
secondVerticalAxis/secondHorizontalAxis, or
secondVerticalAxisRenderer/secondHorizontalAxisRenderer, has the
following effect on the chart:

ColumnChart, LineChart, and AreaChart controls Primary and
secondary series share the horizontalAxis by default, but each
get a separate LinearAxis for their verticalAxis. A second
verticalAxisRenderer is created by default when using multiple
axes.

BarChart controls Primary and secondary series share the
verticalAxis, but by default, each has a separate
horizontalAxis. Two horizontalAxisRenderers are created by
default.

PlotChart and BubbleChart controls Primary and secondary series
have separate horizontal and vertical axes, and all four axis
renderers. Bubble charts continue to share a single radialAxis
among all series.

CartesianChart controls Cartesian charts have no extra axes or
axis renderers by default. 

PieChart controls Secondary series are not supported.

Use the  tag to specify an Array of series
objects that are rendered by using other scales. Any fields
applied to series in this array refer to fields on the
secondDataProvider.

However, I don't understand what the default behavior is when adding
secondSeries, secondHorizontalAxis, and secondVerticalAxis to a
CartesianChart. Specifically, I'm trying to figure out the "axis
affinity" of series added to the secondSeries array, and whether I can
manipulate this. As far as I can tell, a series added to the
secondSeries array uses the (first) horizontalAxis and the
secondVerticalAxis. Is this always the case? Is there any way to control
this behavior? I know that Flex 3 makes multi-axis work easier, but I
need to figure out Flex 2 behavior right now.

you have O(n) memory to spare, you could consider building a hashmap of
the values in Array a, and then walking Array b and checking if each
element is in the hashmap:

var differs:Boolean = (a.length != b.length);
if (!differs) {
  var aContents = new Object();
  a.forEach(function(item:Object, index:int, array:Array):void {
aContents[item] = true;
  });
  differs = b.some(function(item:Object, index:int, array:Array):Boolean
{
return aContents[item] == null;
  });
}

For small-ish arrays, though, I would expect your solution to be faster
than mine (I won't define 'small-ish', since I would honestly be pulling
a number out of my--err, out of thin air).

Also, neither your solution nor mine handles the case where the same
item is in one array twice (yours fails for dupes in a and mine for
dupes in b).

What is the best way to compare two arrays element by element ignoring
the order? My solution:

var differs : Boolean =
 (a.length != b.length) ||
 a.some(
  function(item : Object, index : int, array : Array) : Boolean {
   return (b.indexOf(item) == -1);
  });

May be the better solution exists?


 

Re: [flexcoders] flex version of html float?

[Maciek Sakrejda]

Eric,

I looked at the source, and it seems like your container does not
support horizontalAlign="center" and verticalAlign="middle" (unless I'm
missing something). Any chance of adding that support? It's the main
thing keeping us with the FlowBox from FlexLib. If you're not interested
in adding that support, would you accept a patch (I can't guarantee I'll
have time to actually implement this, but my company is certainly
interested in a better flow container)?

Thanks,

I don't believe that will do it, since the arrays aren't actually equal:
I believe Arrays (for the purposes of object comparison) are only equal

Re: [flexcoders] "With" statement in Pascal what is it in AS3

Right. I've always been wary of the with construct (VB.NET, which I used
to work in, has it), but it can be used rather elegantly:

private function populateNode(d:DataSprite):Boolean
{
var p:Particle = d.props.particle;
if (p == null) {
d.props.particle = (p = _sim.addParticle(mass(d), d.x, d.y));
p.fixed = d.fixed;
} else {
with (p) { x = d.x; y = d.y; fixed = d.fixed; }
}
p.tag = _gen;
return true;
}

Yes, it's the "with" keyword... clever, huh? ;-)

RE: [flexcoders] Be the tree, Bob

[Maciek Sakrejda]

You may also want to consider the WindowShade component from FlexLib,
instead of the ComboBox:
http://flexlib.googlecode.com/svn/trunk/examples/WindowShade/WindowShade_Sample.swf

I found the kmossman example a little confusing to navigate, since
clicking on some things selected them (and collapsed the combobox), and
clicking others expanded the tree. I understand the intent of the
navigation, but it feels a little off. The windowshade may be a slicker
way to accomplish the same requirements you stated originally.

Is there anyway to get the tree view INTO the combo box?



I really like the idea of having a hierarchical menu that looks
exactly like the tree in this example.  I just want it to drop
down and be a menu like the combo box.  I detest the windows
file manager interface (because of its inefficient use of screen
real-estate) and I dont like cascading menu's because I get
really annoyed having to slow down and use my mouse in slow
motion just so I can get to the sub-menu I want.



I think the drop down tree hiearchy within a combobox solves
both of these problems. 1).  Its a great use of screen
real-estate  --- if you are not using it it takes up practically
no room and 2) the hierarchy is persistent and I dont have to be
a jedi master with my mouseand I dont have to move %80 down
and to the right to get the menu I want.



So would it be possible to do a tree in a combo box?  Or, if
thats impossible, I guess I can just put the tree on a
application bar and use it like a menu?

[flexcoders] TextArea and line endings

[Maciek Sakrejda]

We have a TextArea that displays text pulled in from a database. That
text uses Windows line endings: \r\n. The TextArea seems to display a
line break for \r and another for \n. Is there any way around this?
Ideally, we'd like to handle heterogeneous line endings gracefully
(i.e., detect whether a file uses \n or \r\n, and act accordingly).

Any suggestions?

Re: [flexcoders] A Weird DataGrid

[Maciek Sakrejda]

I think you're better off with a custom component (perhaps implemented
as an HBox of List controls). A DataGrid does indeed intend to show
*rows* of data. You'll be fighting the component's basic design idea the
whole way if you start with a DataGrid.

You should also consider the user interface impact of such a component:
it's an intriguing approach to the problem and it could certainly work,
but it's easy to create a usability train wreck when getting too
adventurous in UI design. Make sure to test it with real users as much
as possible.

Subject: [flexcoders] A Weird DataGrid
Date: Tue, 26 Feb 2008 14:48:50 -0800 (PST)


Hi, folks,

I am trying to do something weird with datagrid, which will be described
a
bit later. Please let me have your insights about if it is the right
direction or not.

I would like to have a table about 30 rows by 19 columns, which will
present
information about cars. Each column represents an attribute (e.g., mpg,
acceleration, price) of various cars, and each row (kind of) represent a
car
(e.g., civic, camry, accord, etc.). One thing strange about this table
is
that, all columns are sorted. It is different from the multi-sorting
feature
of AdvancedGrid. Let me show you an example.

Cars | MPG | Price
Accord | 10 mpg (of Civic) | $1 (of Camry)
Civic | 20 mpg (of Accord) | $2 (of Civic)
Camry | 30 mpg (of Camry) | $3 (of Accord)

Since all the columns (i.e., Cars, MPG, Price) are sorted, the rows are
messed up. The first row contains the information about Accord, the MPG
of
Civic, and the price of Camry. In this representation, a row doesn't
represent a specific car any more. So, what I am trying to do is when a
person move a mouse cursor on a cell of Accord, all the cells related
with
Accord will be highlighted. In this way, a user will find out which cell
belongs to Accord through highlights even though rows are messed up.

While implementing this, I found that the underlying data structure does
not
seem to be well matched with this user interface. Each row is treated as
the
same element of a collection. Drawing is done line by line. However, as
you
can see, a row in this strange datagrid represents attributes of
different
elements. Due to this, highlights cannot be drawn line by line. It will
highlights all over the places.

What do you think? Should I build one from scratch? Or, using DataGrid
will
be fine for this?

Regards,
Ji Soo Yi

[flexcoders] Problem with loading xml file using HTTPService or URLLoader

[Maciek Malaszuk]

Hi,

I'm struggling with strange problem.
I'm trying to load XML file in my code which containst data about 
images but thats nor really relevant.

Lets assume i have remote server where i run my code (domain 
x.net).

When i point both httpservice or urlloader to http://mydomain.net/
photos.xml it does work on my local machine but DOES NOT when i copy 
the file to that mydomain server.

This is only one configuration it works on. 

Different scenario i tried and does not work is:
loader pointing to http://mylocalmachineIP/photos.xml (which is 
accessible from the internet) and application neither on local 
machine nor server works.

Did anyone encountered similar problem before? I would expect 
httpservice to be able to access file regardless of its location if 
the url is valid...

Thanks for help as i'm really stuck on this one.

This is variable hoisting in action:

I can't really find a clearer explanation, but the gist of it is that
variable definitions are sometimes moved to the parent block, and
sometimes this results in the sort of weird behavior you're seeing.

That's the how, but I don't really know the why--anyone more savvy about

Re: [flexcoders] Extends vs Implement EventDispatcher

[Maciek Sakrejda]

Unless Flex is doing something really crazy, that should be fine. The
only caveat is that, of course, you'll have to implement all the
IEventDispatcher methods yourself, but you can just pass these off to a
nested EventDispatcher object. In theory, you've got an additional
function call, but in practice, that will not make a difference.

Re: [flexcoders] Extends vs Implement EventDispatcher

[Maciek Sakrejda]

True, but I was under the impression that a virtual method lookup was
cheaper than a whole new method call. Not to mention the bytes and bytes
of overhead from having to keep another object (the nested
EventDispatcher) on the heap ;).

I think Michael A. Jackson said it best: "The First Rule of Program

[flexcoders] Repeater children

[Maciek Sakrejda]

I'm trying to use a repeater to configure n different bars in a foo

(e.g., in pseudo-code

foo
  bars:Array = [ { bar1, bar2, bar3 ];
  ...

where each bar is something like

bar
  label:String
  baz:String
  ...

)

each of the bars has a baz that can be one of five different Strings. My
current approach is to use a repeater:










...

This works very nicely for displaying the correct controls with the
current baz of each bar, but I'm not sure how to come up with a clean
way to "harvest" the settings of each combobox when updating the set. I
don't want to directly listen to each ComboBox CHANGE event because I
want to have update/cancel functionality for the entire group. Is there
a way of doing this cleaner than iterating over the children of barRptr
(presumably FormItems) and doing getChildAt(0) to get the ComboBoxes?

Thanks,

Of course, the searching pays off right *after* I post. If anyone else
is curious:

http://blog.flexexamples.com/2008/05/29/displaying-checkbox-controls-using-the-repeater-in-flex/#more-650

It's kinda sneaky: you set the id of the repeated element as you usually
would, but instead of creating an element with that id, you get an array
of elements with that id, indexed by the order in which the Repeater
repeated them.

Is it? I asked the group about the same thing myself recently, and I
didn't see anything in the Repeater docs in the Flex library reference.
I just checked, and there's no mention in either Flex 2 or 3 docs of
this specific child-naming behavior.

The QuickStart Basics section does explain this, now that I've search
some more, but this should really be in the core library reference.

Just use something like 



Then group[0] will refer to the first one, group[1] will refer to the 
second one, etc. This is pretty thoroughly documented in the docs for 
repeater.

Re: [flexcoders] Re: RadioButtonGroup id not settable using repeater index...

[Maciek Sakrejda]

No, I mean it should be in the library reference:

http://livedocs.adobe.com/flex/2/langref/mx/core/Repeater.html

The behavior is black magic enough that it should really be referenced
there, since it's more fundamental in scope than a tutorial.

But thanks for adding it to your FAQ--that's sure to save some folks
some grief.

Re: [flexcoders] Please share your experiences with Flex 3 charting (visualization component)

[Maciek Sakrejda]

We use Flex for a real-time dashboard at Truviso, and we haven't run
into any major with charts so far. For what it's worth, we're still on
Flex 2, but with FB3, which the bug report states *should* reproduce the
problem (which is odd--FB itself should have nothing to do with this if
the SDK versions are identical). I also noticed from the bug description
that this happens mostly when replacing the dataProvider/series: we keep
the same series/ListCollectionView object but update the contents as new
data comes in.

We definitely depend on Flex Charting for a stable real-time dashboard,
and the data binding paradigm makes this an ideal library for this
purpose. It would be a shame to have to move to something else because
of stability issues.

I wanted to start a thread on user experience on Flex3 charting or 
visualization component.

I had been pusing back hard the last 2 years on moving out realtime 
charting from current serverside image generation to flex charting.

Finally with flex 3 prof , I caved in. Hight cpu usage on servers in 
our production env is of course another motivating factor :)

The state of the charting components seems to be in a bit of a sorry 
state though. Demo looks complelling when used with static data.
Moment we start doing some realtime refesh we're hit with memory and 
cpu usage issues.

Please look at bug http://bugs.adobe.com/jira/browse/SDK-15710 for 
more on this.

These bugs have been filed a while and ago and doesn't seem to have 
been placed high on the priority list.

So I wanted to find out if people in the industry are using flex 
charting solution in realtime dashboards. If so what are your 
experiences.

My experince so far in moving our system to flex charting has been 
quite rocky. here are few issues I'm struggling with

1) With frequent chart updates (say evebry 5 sec), there is lot of 
memory leaks not easily identifiable via flex profiler.
2) Browsers especially IE6 do not claim back memory efficiently.

3) Bar chart frequest update has hig cpu usage

Re: [flexcoders] Bizarre XML data transformation

[Maciek Sakrejda]

Flex sees something that looks like a number in the XML and treats it as
a floating point Number type (since the number in the XML is too big to
fit in an int). Because of the way IEEE floating point works (take a
look if you're interested: http://en.wikipedia.org/wiki/IEEE_754 -- it's
neat), very large and very small numbers lose precision.

The issue has come up on the list before; you can search the archives
for a workaround (I know the cause, but don't know the solution).

Subject: [flexcoders] Bizarre XML data transformation
Date: Wed, 17 Sep 2008 19:09:55 -

Once again, I've hit a roadblock with Flex for something that should
be easy as pie.

Here's the problem: I'm loading in an XML feed from Flickr, a list of
photoset IDs. There's nothing wrong or unusual about the XML document. 

I load the XML into an ArrayCollection, and can view all the data just
fine, except the ONE element I need... the ID number. Flex is
screwing it up somehow.

For example, the ID number in the XML file looks like this:
72157607109678346

However, when Flex returns the ID number, it becomes: 72157607109678350

Every ID is changed like that, but it's not consistent. The first
one, 4 is added to the ID. In the next, 12 is subtracted. No rhyme
or reason.

What Flex is doing to this number or why it's doing it escapes me. 
I've tried copying the XML file locally and appending the ID with a
character... it then comes across fine. So Flex thinks the ID is some
kind of number datatype, and manipulating it somehow. 

Any idea how to make Flex cut that out?

Re: [flexcoders] Re: as3CoreLib

For what it's worth, crazy or not, it is reasonably common for small
projects to have svn-(or other vcs)-only access to source. Packaging up
source releases is just another piece of work for the maintainers. It
does seem that something like corelib should have a source package,
though.

[flexcoders] horizontal axis chart label size when chart has minimal height

[Maciek Sakrejda]

When I resize a chart (e.g., Column), below a certain size (seems to be
~100-200 pixels), the labels on the horizontal axis shrink into
illegibility. Is there a way to prevent the labels from shrinking?

For an example of what I'm talking about, go to
http://examples.adobe.com/flex2/inproduct/sdk/explorer/explorer.html

, select Charts > Chart Controls > BarChart, and drag the divider of the
HDividedBox on the right up until just before the chart window itself
gets scrollbars. The labels shrink down to just a few pixels tall and
are completely illegible by the end.

I would like to keep the labels at the given height (notice that, e.g.,
the vertical axis labels on the AxisRenderer example do not shrink this
way), and keep shrinking the chart instead. The behavior seems
inconsistent: sometimes the labels shrink and sometimes they don't. And
it's not just related to horizontal versus vertical: take a look at the
AreaChart example--both sets of labels shrink when you drag in the right
browser edge to shrink the chart, but neither set changes when you drag
up the divider below.

Any thoughts?

Thanks,

Tim,

Do you know when you set the gutter? The gutter set is throwing a null

suppose that's partially why, but I hope I can work around that...

Hey Maciek,

Setting an explicit gutter value fixed a similar problem that had once
with the labels on a chart. If I remember correctly, the label's font
will become illegible when the labelSizeLimt is met, or the label
dimensions force the font to be below the fontSize; because the label's
container has smaller dimensions than the label itself.

Re: [flexcoders] Re: horizontal axis chart label size when chart has minimal height

[Maciek Sakrejda]

Sorry--I wasn't clear. There's a gutter property on the AxisRenderer,
but when I set it explicitly, one of the methods called by the setter
throws a null reference error (presumably because I'm calling the setter
at the wrong time). I was asking when to call the gutter setter.

I think it's a style, like most things with charts.

[flexcoders] URLRequest, ByteArray, and the 0 byte

[Maciek Sakrejda]

I've run into an interesting problem with URLRequest, navigateToURL, and
ByteArray when sending a zero byte:

var bytes:ByteArray = new ByteArray();
bytes.writeByte(1);
bytes.writeByte(1);
bytes.writeByte(1);
bytes.writeByte(1);

requestHeader = new URLRequestHeader("Content-type",
"application/octet-stream");
// Where ../../test is just a valid dummy url--it doesn't matter what it
// actually does with the request
request:URLRequest = new URLRequest("../../test");
request.requestHeaders.push(header);
request.method = URLRequestMethod.POST;
request.data = bytes;
navigateToURL(request, "_blank");


I write four bytes above, because that seems to be a minimum for
URLRequest (if I write just one byte, the Content-Length header is set
to 4 anyway), but that's a separate issue.

If I change one of those

bytes.writeByte(1)

to

bytes.writeByte(0)

The byte array seems to be truncated to the location of that byte. In
general, any ByteArray sent as a data property payload of a URLRequest
seems to be truncated to the location of the first zero byte. I've
confirmed this by checking the Content-Length header of the POST request
(in fact, if the *first* byte is zero, the request seems to be turned
into a GET--which is even weirder).

I'm using FP 9.0.124.0 on Linux. I just tested on a colleague's machine,
and this seems to work fine in FP on Vista. Is this a known issue? Is
there any way around this?

Re: [flexcoders] compc: locking assertion failure

[Maciek Sakrejda]

So after some research, this seems to be a Sun JRE problem:

http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6532373

Any idea whether the assertion failure really is harmless, as it seems
to be? This seems to affect a number of Java programs for some people,
and some of them crash when the assertion is triggered. Is it safe to
just ignore it?

Thanks,

Re: [flexcoders] URLRequest, ByteArray, and the 0 byte

[Maciek Sakrejda]

Hi all,

I've create the following ticket:

http://bugs.adobe.com/jira/browse/FP-708

It seems to be a core Flash Player issue, and not anything Flex-related,
but if you care about Linux Flash Player, I'm not above begging for
votes.

Re: [flexcoders] URLRequest, ByteArray, and the 0 byte

We're also working around this by Base64-encoding, but this is clearly
less than ideal. It definitely seems like a Flash Player bug. We ran
into this when doing AlivePDF REMOTE saves (i.e., bouncing the file off
the server). Do you know when you ran into this, Troy? I tested our
particular problem on Windows and on OS X last week, and neither had the
issue.

Just ran into a similar issue under OSX/Windows. If I tried to stick a
ByteArray into a URLVariables, no matter what combination of
operations I'd make, somewhere along the line it got converted to a
String and thus truncated at the first zero byte (because I assume
Flash uses null-terminated strings internally).

To fix it, I ended up encoding the data in Base64 before sticking it
into the URLVariables, which I think was actually a win over the
URL-encoding (e.g. %03%38%99...) anyway.

In regards to your POST/GET issue, Flash Player appears to convert
empty POSTs to GETs, which would explain why 0 has the first byte
(thus a zero-length data) would turn your POST into a GET.

Troy.



 

Re: [flexcoders] URLRequest, ByteArray, and the 0 byte

[Maciek Sakrejda]

That is not what the documentation says:

If the object is a ByteArray object, the binary data of the ByteArray
object is used as POST data. For GET, data of ByteArray type is not
supported. Also, data of ByteArray type is not supported for
FileReference.upload() and FileReference.download().

from
http://livedocs.adobe.com/flex/3/langref/flash/net/URLRequest.html#data

I was doing a POST with a ByteArray as the data. Again, this works
correctly under Windows and OS X, so I'm pretty sure this is a Player
bug under Linux.

Re: [flexcoders] URLRequest, ByteArray, and the 0 byte

[Maciek Sakrejda]

Ah, interesting. This seems related, but different. I was just setting
URLRequest.data to a ByteArray directly. In your case, if I understand
application/x-www-form-urlencoded correctly, then zero bytes should just
be replaced with %00. Have you filed a bug? I'd like to add that to my
Adobe JIRA watch list if so.

Re: [flexcoders] URLRequest, ByteArray, and the 0 byte

[Maciek Sakrejda]

I'm not sure I agree--if it's a "feature" of the implementation that
prevents valid use of the API, that sounds like a bug ;). As far as I
can tell, a null byte should be encoded to %00 in the
application/x-form-urlencoded scheme and is a valid character. If
calling toString() on a ByteArray truncates it, then the implementation
shouldn't be doing that. String does seem to handle null bytes correctly
in other cases (try trace(String.fromCharCode(1,0,2).length) ), so there
should be no problem here.

Also:

Not in Linux Flash Player--that was my original point.

Thanks for the feedback, though--it's always interesting to dive into
this low-level stuff.

It does work correctly if you set URLRequest.data to a ByteArray, but
in my example I was setting URLVariables.data (which could be called
anything, it's just a named property) to a ByteArray, and URLVariables
(apparently) calls toString on each property's value *before*
URL-encoding them, which is the problem. So, not necessarily a bug,
just an undocumented "feature" of the implementation. Since
URLVariables does the encoding, I expected/assumed (since it wasn't
explicitly documented) it would it encode the ByteArray as bytes, %00
and all.

Re: [flexcoders] SecurityError #2048 20 seconds after Socket closure.

[Maciek Sakrejda]

Samuel,

Don't know if this is helpful, but when working with URLStream, we ran
into a situation where calling close() did not actually do anything
(i.e., it did not issue a TCP FIN--we watched for this with tcpdump). We
did not encounter any security errors, so I don't know if this is
related, but I think the easiest way to figure out what's going on might
be to break out something like tcpdump or Wireshark...

Subject: [flexcoders] SecurityError #2048 20 seconds after Socket
closure.
Date: Thu, 02 Oct 2008 11:48:22 -

Hello,

I've met a very unexpected problem with a Socket connection. I'm very 
used to client-server communication, and it's the first time I 
encounter such behaviour.

I have an AS3 application, connected to a custom Java server using the 
Socket class.

The server is run on a distant computer (let's say its hostname is 
'javaserver'), listening on port , along with a crossdomain server 
which deliver an authorization XML on port 843 ().

On the client computer, I have a FlashPlayerTrust file that allow my 
SWF to be on the Trusted sandbox.

The connection works just fine. I can send and receive binary data 
perfectly. At a given time in my communication exchange, the server 
closes the socket.

The CLOSE event is thrown in my Flash application correctly.

But 20 seconds after that (precisely 20s), my closed connection throws 
a SecurityError #2048 :

> Error#2048: Security Sandbox violation. Cannot load resource from 
javaserver:.

I can't figure why this is happening. In my experience, and according 
to the documentation, a SecurityError (or a SECURITY_ERROR event, if 
listened) can be thrown only when using connect() with a non-
authorized distant host (which is not the case, since my SWF is in the 
Trusted sandbox), or while connecting to a port below 1024 on a Web 
execution context (which is not my case, since I use a connection to 
the port , using a Standalone player).

This problem is happening with the Standalone Flash Player 10.0.0 
b591, but also with the Player 9.0.124.

Any idea?

Thank you very much.




 

Re: [flexcoders] Prototyping a form

[Maciek Sakrejda]

It's possible if you tell us the compilation errors you're hitting.
However, in this case, you're probably hitting something telling you
that you can't override something not marked for override, so you need
to add the 'override' keyword to the completeParameters() function
definition.

Re: [flexcoders] Re: Prototyping a form

[Maciek Sakrejda]

Ok, what's the context here? If this is the error, it could be that
you're not defining the method in the parent form. This is true even if
the method doesn't do anything and *must* be overridden in child
forms--most object-oriented languages provide the 'abstract' keyword to
ensure this, but ActionScript doesn't. Then specify the 'override'
keyword on child forms as I mentioned before.

If this still isn't it, can you please post the parent and child forms
for context?

Re: [flexcoders] Re: Matching n groups with a regex?

[Maciek Sakrejda]

Josh,

For what it's worth, \w will match '_' (it's true of REs pretty much
everywhere, and I just tried and as3 is the same). I played around with
your example a bit, but I can't offer any more insight. The closest I
got would leave stray '.'s on the ends of the matches, and you'd have to
clean those up manually anyway. I need to learn lookahead...

Alternately, you could String.split('.') and validate the individual
tokens.

I need to do two things:

1: make sure the string matches /^[a-zA-Z0-9_]+(?:\.[a-zA-Z0-9_]+)+$/
2: extract all the individual words (not the dots)

I Can't use \w because it doesn't match "_".

At the moment I'm just using String.split(".") after using the regexp to
test validity.

My pattern works on your example of
"*&%*&^objectA()*&)(*&908objectB,objectC"

The resulting array contains:
objectA
908objectB
objectC

Which is what I thought you wanted.


Also, the problem in your RE *is* the non-capturing group which
is
consuming your 'objectB.' You can verify this by using a
lookahead
assertion (?=) instead of the noncapture (?:) group.

var patt:RegExp = /([a-zA-Z0-9_]+)(?=\.?(?:[a-zA-Z0-9_]*))/g;

This pattern results in the same output as my simple pattern
using
lookahead assertions.

If these aren't the results you were looking for let me know and
I can
take another look.

Re: [flexcoders] skinClass in external library

[Maciek Sakrejda]

Short answer: no.

Longer answer: What exactly are you trying to do? You're defining assets
in an external swc, configuring your swf to use those assets, but you
don't want a dependency on the swc? That doesn't really make any sense:
the embedded skin "lives in" the swc. What do you expect to happen when
the swf references assets that are not there?

Subject: [flexcoders] skinClass in external library
Date: Wed, 08 Oct 2008 11:24:16 -

My scenario:

I have a flex builder workspace with the main flex application, and
many flex libraries which are linked to the main flex app.
One of that libraries contains the assets, styleSheets... it's the
theme library.
In the stylesheet file of this library, there are some styles defined
which use the Embed(skinClass='') directive, this skin
classes are in a swc file created with flash. This swc file is added
to the build path of the theme library.
Some of this styles are used in the main flex app.

When I try to compile the whole thing, I got a "class for skin
'' not found" error from the main app.
If I compile the theme library only, i got no errors.

The only solution I've found is to add the swc file to the build path
of the main app.

But, and here is my question: I don't want my main flex app to depend
on the swc file. Is there any way I can accomplish that?




 

Re: [flexcoders] Re: skinClass in external library

[Maciek Sakrejda]

Ah, I see. I didn't realize that's what Albert was asking ("I don't want
my main flex app to depend on the swc file."). If that's the case, then
yes--he can compile the resources into a SWF and depend on any SWF that
delivers all the relevant resources, not specifically just that one.

Thanks for the clarification.

It is possible using ANT scripts and  to compile your
CSS sheet containing skinClass reference.

Maciek, dependency can be satisfied with style sheets loaded at
runtime. This way you can change skin without recompiling your
application.

My guess is that you have malformed (or at least questionably-formed)

Re: [flexcoders] Java-like equals() method?

[Maciek Sakrejda]

Frank,

There's no .equals() in actionscript unless you implement it yourself.
Without hearing more about the context, it's hard to tell whether
Jitendra's data binding solution would work for this specific problem
(data binding would effectively set the list selection to an object that
is not in the list--I'm not sure what happens there), but you might run
into a need for .equals() further down the line. We did, and since all
of our VOs inherit from one VO base object, we just implement .equals()
in these as necessary. It seems rather horrifying that there's
no .equals() at first, but you don't really need it that often...

Subject: [flexcoders] Java-like equals() method?
Date: Sat, 11 Oct 2008 02:54:18 -

Hi, 

I've been searching for a good solution to implementing object equality.
I'm familiar with 
ObjectUtil, etc., but it still makes things harder than they should be. 

It may be best to illustrate this with an example. Suppose I have a
ComboBox with an 
ArrayCollection as a data provider. The ArrayCollection is populated
with value objects 
from the server, e.g., User objects. Suppose that I have a Task class,
and a Task may 
have an assignedToUser property, which is a User instance. When the
someone selects a 
Task (say, in a master-detail view), I would like the ComboBox to set
its selectedItem to 
the user for the given Task, i.e., combBox.selectedItem =
myUser.assignedToUser.

The problem is that no Task in the ComboBox's data provider and the
User's 
assignedToUser property are ever equal using the == or === operators. 

So I would like to implement a custom equality for User, and have the
ComboBox use that 
to set its selectedItem to the specified user. In Java, this is easily
done by overriding the 
equals() and hashCode() methods of User. 

Any suggestions on how to achieve something similar in Flex would be
much appreciated.

Thanks, 

-- Frank
