In testing via the Profiler, binding UI objects in a module to a model
(even if local to the module) appears to be causing a module's failure
to unload. This happens as soon as the UI component becomes active. In
fact, even if the source object (data provider) is set to null, the
binding persists and will prevent a module from unloading. Does this
issue have to be such a PITA? It appears that using curly braces for
binding in MXML can create Modules that won't unload. 

In FP 10, the Loader class has the new unloadAndStop() method. Would be
extremely handy to have something similar for Modules. Basically you
want to remove all listeners to a model and then unload the module. 

Seeking enlightenment - anyone got any?

 Probably not; I have enough trouble as it is trying to get rid of all
 the space used by the axes - I've made the axes invisible via numerous

 being allocated to it.

Re: [flexcoders] Unloading Modules - Binding is the Enemy?

2009-04-23 Thread Pedro Sena

Hi Jeff,

The fact that you unload a module does not mean that it will be garbage
collected(the memory won't be released as soon as you unload your module).
Unload the module makes it available for garbage collection.

As far as I know, the module 'garbage' will be collected by the GC when
necessary, so don't think that unload a module means free memory in the
exactly same moment.

I'm supposing that you are testing in your development machine(probably a
good machine) so I suggest you to test it in a limited machine to see if
this memory is released when it is *necessary* , that is the point.

RE: [flexcoders] Unloading Modules - Binding is the Enemy?

Pedro,
 
I've been running the GC immediately after unload - programmatically.
The module instance is released immediately if binding is inactive.  The
moment binding becomes active to a UI element of the Module, the
instance will not be released.  I was thinking that having the model
object I'm binding to be local to the module would address the behavior,
but sadly it does not appear to work.

Re: [flexcoders] Unloading Modules - Binding is the Enemy?

2009-04-23 Thread Pedro Sena

Jeff,

Calling GC programmatically does not mean that it will be executed.

Like java, the GC in flex is not under programmer's control. You may call
it, but it won't be executed if it is not necessary.

Clicking the Run Garbage Collector button does not guarantee that all
objects that are eligible for garbage collection will be garbage collected.
Garbage collection is typically triggered by the allocation of memory for
new resources.

RE: [flexcoders] Unloading Modules - Binding is the Enemy?

Thanks Pedro,
 
I've seen what your describing in the docs - I'm looking at this via the
profiler which is giving me feedback as to number of live instances,
etc. 
 
Here's what I'm basing my statements on:.
 
1) I start up my app, which loads modules at runtime based upon user
choice from a menu.
 
2) Module exectues Cairngorm Event/Command/Delegate to get array to
populate a combo box. I'm passing a reference to the module's model in
my Cairngorm event and the model is updated upon completion of the
Command.
 
3) Combobox is bound (via MXML) to the model.
 
4) If I don't interact with the combobox, I can then logout and unload
the module successfully. The profiler tells me there was previously 1
instance of the module and now there are zero instances.
 
5) If I make the combobox active (by interacting with it in any way),
and then logout, the module remains in memory, with the profiler
reporting one instance instead of zero.
 
6) If I then login again, the Profiler reports 2 active instances of the
module.  Note that any model objects are duplicated as well. For
example, if my list of suppliers (used to popuate my combobox) (a
strongly typed AS class) was previously 64, the profiler now reports
there are 128 instances.  
 
There's my behavior.  When my UI object (in this case ComboBox), becomes
active, the binding becomes active and then the module will not unload,
even if I set the modules model to null before attempting to unload.  It
would appear that I need to invalidate all outstanding bindings to any
data object before the module will fully unload.  This would seem to
indicate that MXML binding (via curly braces) isn't going to allow this.

It does sound like you are describing the bug where the focus manager

unloading...

If you lose the combobox focus, does the module unload?

[flexcoders] DataGrid combobox erasing items from it's list

2009-04-23 Thread netdeep


I have a DataGrid that is linked to an array of custom data objects which I 
call a seriesList.  You are supposed to be able to choose the name of each 
series via a combobox in the datagrid.  It works fine except when the user 
selects the combobox and then clicks somewhere else in the interface, which 
closes the combobox and erases whichever item is previously selected!

Re: [flexcoders] e4x challenge

2009-04-23 Thread Daniel Freiman

If you want to select them, then:

XMLList list = xml.descendants().(@type = file)

otherwise, i'd still get that list and then loop through it and delete each
by doing (exact code might need some cleaning):

for (each item:XML in list) {
   delete item.parent()[item.childIndex()];
}

RE: [flexcoders] Unloading Modules - Binding is the Enemy?

Gregor,
 
Very interesting indeed.  If I login, load the module, interact with the
combobox, logout, the instance remains in the profiler.  However if I do
all that and THEN load another module and logout, the number of
instances of the first module goes to zero.  These modules are being
loaded into a ViewStack, BTW.  
 
Is this the FocusManager bug you described?  Is there a workaround?
 
I'd be thrilled to discover that Binding was not the culprit here.

It does sound like you are describing the bug where the focus
manager holds onto the reference of the combo box and stops the module
unloading...

If you lose the combobox focus, does the module unload?

Enemy?

 






Thanks Pedro,

 

I've seen what your describing in the docs - I'm looking at this
via the profiler which is giving me feedback as to number of live
instances, etc. 

 

Here's what I'm basing my statements on:.

 

1) I start up my app, which loads modules at runtime based upon
user choice from a menu.

 

2) Module exectues Cairngorm Event/Command/Delegate to get array
to populate a combo box. I'm passing a reference to the module's model
in my Cairngorm event and the model is updated upon completion of the
Command.

 

3) Combobox is bound (via MXML) to the model.

 

4) If I don't interact with the combobox, I can then logout and
unload the module successfully. The profiler tells me there was
previously 1 instance of the module and now there are zero instances.

 

5) If I make the combobox active (by interacting with it in any
way), and then logout, the module remains in memory, with the profiler
reporting one instance instead of zero.

 

6) If I then login again, the Profiler reports 2 active
instances of the module.  Note that any model objects are duplicated as
well. For example, if my list of suppliers (used to popuate my combobox)
(a strongly typed AS class) was previously 64, the profiler now reports
there are 128 instances.  

 

There's my behavior.  When my UI object (in this case ComboBox),
becomes active, the binding becomes active and then the module will not
unload, even if I set the modules model to null before attempting to
unload.  It would appear that I need to invalidate all outstanding
bindings to any data object before the module will fully unload.  This
would seem to indicate that MXML binding (via curly braces) isn't going
to allow this.

RE: [flexcoders] Re: HTTPService mistery

What is the result format of the HTTPService call?  The default object
causes the flex client to process the incoming data into a tree of dynamic
objects.  The speed of this process would be subject to the local cpu.  You
could set resultFormat to e4x, and re-run the benchmarks.

While it seems to me I am missing something obvious I am pretty sertant it
is somewhere in the send command. I have traced an execution to the point
that for a low end box it takes about 5 sec. between a send command and an
HTTPService callback function call. I have timed my server and it does not
take time at all. I timed the server for both my development computer and a
low level box. Server time is exactly the same. (what else whould one
expect?) But time it tales for an execution to get into a callback function
is very different. So, I am assuming that it takes some time for a low end
box to send a data request to the server.

[flexcoders] Re: Flash player 10 Debug not recognized in FB3

2009-04-23 Thread Jason

 For FB3 you also need to make sure that you have I believe FB 3.0.2 in order 
 to use FP 10 Debug player properly. Less then that and I was getting a ton 
 warnings about not having the debug player.

Thanks Mark, I see my version of Flexbuilder is 3.0.1, not 3.0.2!  I'll try 
upgrading!

Everyone else, thanks for responding - a lot of you have been recommending I 
understand there are two different versions of the Flash player - the regular 
release and the debug version.  I'm not sure how I gave the impression I didn't 
understand that, even from the beginning, I clearly do - especially if you read 
my original post.  Funny, because I titled this thread, Flash player 10 
Debug  Maybe when Alex called them binaries instead of players and I was 
confused by that and asked a question about what he meant, that threw some of 
you off. Sorry! ;)  It was just because never heard of the Flash players being 
called a binaries before - so I didn't know if he was talking about something 
else entirely. Also, as I stated, I have run the uinstaller and then the 
installer for the DEBUG version of the player without luck, as I mentioned.  

So sorry for any confusion, didn't mean to waste your time responding to the 
wrong question.  My problem is that after uninstalling FP10 and re-installing 
FP10 DEBUG version, FB3 still does not recognize it.  

I'm going to take Mark's advice and upgrade FB3 and see if that works.  Thanks 
everyone for your help!

[flexcoders] Working With Dynamic Datagrid

2009-04-23 Thread blkmajk111

Hey All,

I'm having an issue that I was hoping someone can help me out with.

I need to populate a datagrid based on XML being returned to Flex. The 
structure of the XML is as follows: 

root
 lab id=2 title=Chemical Materials
  assignment assignmentid=2 name=s2 s2 grade=B/
  assignment assignmentid=4  name=s1 s1 grade=C/
  assignment assignmentid=6  name=John Smith grade=B/
 /lab
 lab id=8 title=BioChem
  assignment assignmentid=3 name=s2 s2 grade=F/
  assignment assignmentid=5 name=John Smith grade=D/
 /lab
/root

When this XML gets returned to Flex I need to throw it into a Datagrid for 
diaplay. The catch is there can be any number of columns in the datagrid 
becasue the assignments can be of different quantities.

Here is the code that I am using to make the grid:

 private function getGradebookSectionDb(event:ResultEvent):void{
  var gradebookBySection:XMLList = event.result.lab;

  var cols:Array=new Array;

  for (var i:int=0;igradebookBySection.length();i++){
var col:DataGridColumn=new DataGridColumn();
col.headertext=gradebookbysection[...@title.toxmlstring();
  
col.dataField=gradebookBySection[i].children()@grade.toxmlstring();
cols.push(col);
gradebookDatagrid.columns=cols;
gradebookDatagrid.visible=true; 
 }

When I do this, the columns get created from the XML very nicely with the 
headers displaying correctly but there is no data showing up in the columns. I 
would like to get one of the attribute values in each column but for some 
reason nothing comes up. When I do a trace on the col.datafield I get the 
right information coming back in the trace but nothing shows up in the column.

I would have just assigned the XML as a datapovider to the datagrid but as the 
amount of assignments returned can change, I saw this as my only option.

Can anyone help me with this?

Thanks!

 super.htmlText = value;
 }
 else
 {
 super.htmlText = value;
 }
 }

 public function newInstance():*

 return new AminoAcidRenderer();
 }
 ]]
 /mx:Script
 /mx:Label

 But, alas, there are a couple of problems here. First, the
 string.replace() only affects the first occurrence of the pattern and
 not every occurrence (I wonder if a regex would remedy that?). Then
 although the substitution gets done for those patterns that are found,
 the htmlText isn't getting rendered...and I wonder if it's due to the
 function set text instead of function set htmlText, which I tried and
 literally got nothing.

 I've also looked at the TextRange that someone else suggested but
 not sure how to possibly use that as it needs a begin/end index and the
 letters are sporadic from one string to the next.

 How would I setup the labelFunction to parse the string to get the
 letters?

 Thanks in advance!

[flexcoders] Re: maxWidth property not working on Advanced DataGrid

2009-04-23 Thread labosox

I placed the height at 80 so that I could force a vertical scroll bar. That way 
I didnt have to add more data to turn on the vertical scroll bar.

basically I need a grid to resize its entire width on a column resize event. 
When the grid's width is too large to fit in a panel, I want the grids 
horizontal scroll bar to come on. The code below doesnt work if a vertical 
scroll bar is present. 

Let me know if the scenario doesnt make sense.

RE: [flexcoders] Working With Dynamic Datagrid

I don't see where you are you assigning the dataProvider.  Either assign the
data to a bindable var  in the result handler, of assign the dataProvider
directly.  If assigning directly, you might need to use callLater()

Subject: [flexcoders] Working With Dynamic Datagrid

 






Hey All,

I'm having an issue that I was hoping someone can help me out with.

I need to populate a datagrid based on XML being returned to Flex. The
structure of the XML is as follows: 

root
lab id=2 title=Chemical Materials
assignment assignmentid=2 name=s2 s2 grade=B/
assignment assignmentid=4 name=s1 s1 grade=C/
assignment assignmentid=6 name=John Smith grade=B/
/lab
lab id=8 title=BioChem
assignment assignmentid=3 name=s2 s2 grade=F/
assignment assignmentid=5 name=John Smith grade=D/
/lab
/root

When this XML gets returned to Flex I need to throw it into a Datagrid for
diaplay. The catch is there can be any number of columns in the datagrid
becasue the assignments can be of different quantities.

Here is the code that I am using to make the grid:

private function getGradebookSectionDb(event:ResultEvent):void{
var gradebookBySection:XMLList = event.result.lab;

var cols:Array=new Array;

for (var i:int=0;igradebookBySection.length();i++){
var col:DataGridColumn=new DataGridColumn();
col.headertext=gradebookbysection[...@title.toxmlstring();
col.dataField=gradebookBySection[i].children()@grade.toxmlstring();
cols.push(col);
gradebookDatagrid.columns=cols;
gradebookDatagrid.visible=true; 
}

When I do this, the columns get created from the XML very nicely with the
headers displaying correctly but there is no data showing up in the columns.
I would like to get one of the attribute values in each column but for some
reason nothing comes up. When I do a trace on the col.datafield I get the
right information coming back in the trace but nothing shows up in the
column.

I would have just assigned the XML as a datapovider to the datagrid but as
the amount of assignments returned can change, I saw this as my only option.

[flexcoders] 360|Whisperings online Technical articles, looking for authors.

2009-04-23 Thread John Wilker

For those that don't know me, I'm John Wilker, co-founder of 360|Conferences
(360|Flex, and 360|iDev). Tom Ortega and I have created a new venture to go
along with our community oriented conferences. 360|Whisperings (
http://www.360whisperings.com). For those of you who own Amazon Kindles you
know that Whispernet is the delivery medium for purchased content.

We've created a site where people can come and browse the available content
and instead of subscribing for all you can eat, simply purchase the articles
that they want. Subscriptions are great, but you have to get your money's
worth. We're looking to go more the iTunes route, for a buck or two, get the
same quality article you would from a pay site or journal, knowing it's
quality content, and not have to pay for the content you don't want or need.

We're not just going to be limited to the Kindle (and the iPhone/iTouch
technically) but that's a good turn key place to start. Our goal is to offer
content in as many formats as we can (PDF, ePub, Mobi, PRC, etc) so that
everyone can get access. We'll take care of editing and marketing the
content and reporting on sales. The split is 60/40 us, in exchange for the
stuff I just mentioned. Our conference sites will link to and highlight
content as well as the primary site itself. I know it seems like small
change, and it is to start, but the more articles we get, the more momentum
this offering builds.

We've got a few folks signed on right now, coming up with article ideas.
We're hoping to get a few more folks for the official launch so that we've
got a good library set up and ready for folks. Why subscribe to sites and
journals, and have no idea how much value you'll get from the content? Just
pay for what you want. We're looking for technical content on any topic; CF,
FLex, Flash, AIR, Java, etc.

If you want to select them, then:

otherwise, i'd still get that list and then loop through it and delete each

for (each item:XML in list) {

RE: [flexcoders] DataGrid combobox erasing items from it's list

So the scenario is:

1.  user clicks cell, CB editor appears
2.  user clicks away somewhere, without selecting anything
3.  ComboBox closes
4.  an empty string is stored in the dataProvider

 

Yes?  Is the change event and handler firing in this case?

 

If so, then I think you need to make the renderer set the ComboBox's
selectedIndex to display the current value.  Thus however the change event
was caused, the correct value would be put back in the property.

 

I think you would want this behavior anyway.  Note you can't directly set
selectedItem, but must loop over the dataProvider comparing property values,
then using the loop index to set the selectedIndex.

Thanks Pedro,

I've seen what your describing in the docs - I'm looking at this via the
profiler which is giving me feedback as to number of live instances, etc.

Here's what I'm basing my statements on:.

1) I start up my app, which loads modules at runtime based upon user choice
from a menu.

2) Module exectues Cairngorm Event/Command/Delegate to get array to
populate a combo box. I'm passing a reference to the module's model in my
Cairngorm event and the model is updated upon completion of the Command.

3) Combobox is bound (via MXML) to the model.

4) If I don't interact with the combobox, I can then logout and unload the
module successfully. The profiler tells me there was previously 1 instance
of the module and now there are zero instances.

5) If I make the combobox active (by interacting with it in any way), and
then logout, the module remains in memory, with the profiler reporting one
instance instead of zero.

6) If I then login again, the Profiler reports 2 active instances of the
module. Note that any model objects are duplicated as well. For example, if
my list of suppliers (used to popuate my combobox) (a strongly typed AS
class) was previously 64, the profiler now reports there are 128 instances.

There's my behavior. When my UI object (in this case ComboBox), becomes
active, the binding becomes active and then the module will not unload, even
if I set the modules model to null before attempting to unload. It would
appear that I need to invalidate all outstanding bindings to any data object
before the module will fully unload. This would seem to indicate that MXML
binding (via curly braces) isn't going to allow this.

I expect a chart that has myName and name3 across the

 Trying one more time. Surely there's a call (validateNow() ?,
 invalidateDisplayList() ? that would force a column chart to display
 properly after its series array has been dynamically constructed?

[flexcoders] Re: Flash/FLex gravity

Not sure if the post went through.

I have the book now. I am trying to make it work and I am almost there, but the 
sprite is only glides correctly when thrown if I drag from top right to lower 
left or lower left to top right.

If I throw it directly to the right it moves up and if I throw it to directly 
to the left it goes down. If I throw it up it goes to the right. And if I throw 
it down it moves to the left.

Here is the code (_object is the sprite being throw):

if(_drag == true){

var diffx:Number = initX - mx;
var diffy:Number = initY - my; 

var speed:Number = 12;
var angle:Number = Math.atan2( diffx, diffy );
//var radians:Number = deg2rad(angle);
var xVel:Number = Math.cos(angle) * speed;
var yVel:Number = Math.sin(angle) * speed;

function deg2rad(deg:Number):Number {
return deg * (Math.PI/180);
}

function onLoop(evt:Event):void {
_object.x += xVel;
_object.y += yVel;
 
xVel *= 0.9;
yVel *= 0.9;

if (xVel  0.05  yVel  0.05) {
_drag = false;
 
_stage.removeEventListener(Event.ENTER_FRAME, onLoop, false);

So the scenario is:

 1.  user clicks cell, CB editor appears
 2.  user clicks away somewhere, without selecting anything
 3.  ComboBox closes
 4.  an empty string is stored in the dataProvider

Yes?  Is the change event and handler firing in this case?

If so, then I think you need to make the renderer set the ComboBox's 
selectedIndex to display the current value.  Thus however the change event was 
caused, the correct value would be put back in the property.

I think you would want this behavior anyway.  Note you can't directly set 
selectedItem, but must loop over the dataProvider comparing property values, 
then using the loop index to set the selectedIndex.

Hi,

In My application we are purly following Cairngorm framework. I am not much

Is anyone have any suggestions to improve the performance.

[flexcoders] Re: DataGrid combobox erasing items from it's list

2009-04-23 Thread Tim Hoff


Hi,

Your code looks fine.  But, I believe that you need to handle the
itemEditEnd event, for the DataGrid:

mx:DataGrid itemEditEnd=onItemEditEnd(event);/

  Something like this:

private function onItemEditEnd(event:DataGridEvent):void
{
  // Check the reason for the event.
  if (event.reason == DataGridEventReason.CANCELLED)
  {
   // Do not update cell.
   return;
  }

  // Get the new data value from the editor.
  var newData:String =
ComboBox(event.currentTarget.itemEditorInstance).selectedLabel;

  // Determine if the new value is an empty String.
  if(newData == )
  {
   // Prevent the user from removing focus,   and leave the cell
editor open.
   event.preventDefault();
   return;
  }
}

 I'd like to create a dynamic Flex Stacked Column Chart

 2. Iterate through chartIemArrayColl and only create a a
 new columnseries object if there does not already exist
 on for that 'selection'. Add this columnseries to the
 columnset
 3. Apply this to the chart

 Note: I used secondSeries instead of series because of a
 known defect in Flex that makes the charts off center if
 series is used.

 Problems:
 
 1. The chartIemArrayColl contains items that contain the
 same 'name' but different 'value' and different
 'selection'. However, in this case that particular
 'name' is printed on the x-axis multiple times (not
 correct)
 2. The 'selection' should be the legend, but when it is
 graphed it does not seem as though it is connected to
 the items actually charted

 What I'd like to achieve:
 
 1. Column chart with a legend that contains only values
 of the 'selection'
 2. Stacked Column chart that contains values where I can
 chart the following example:

 item1 (name=myName, selection=sel1, value=4)
 item2 (name=myName, selection=sel2, value=6)
 item3 (name=name3, selection=sel1, value=8)

 I expect a chart that has myName and name3 across the
 x-axis (myName should only appear once). A column should
 appear at myName that has one color/selection (value 4)
 stacked on top of another (value 6). A column should be
 at name3 with the same color/selection as item1 (value
 8).

 Can you please help me with this? Thanks so much in

[flexcoders] How improve performance

Hi,

In My application we are purly following Cairngorm framework. I am not much 
deep into the flex framework and its performance but my application is like the 
longer the application is in use, the slower it runs. 

Is anyone have any suggestions to improve the performance.

I truly appreciate your valuable suggestions.

Use the profiler to see if you have a memory leak somewhere. Sounds  
like perhaps you are creating objects but not destroying them once  
you're done with them.

[flexcoders] module loading and progress load slow?

2009-04-23 Thread Jason B

loading modules 

I've been rearranging my application to use modules to reduce load time and 
prepare it to handle later larger development etc...
All is well I've got it loading modules and such and learned a lot over the 
past few days. 

I have several modules that have large images it uses with source= and some 
other swf's it loadsI prefer not to allow caching since these items change 
a lot.

On a localhost connection (dev) It can take 10 seconds to load the module etc.
At first I thought it was needing a preloading technique that adobe offers so i 
tried that to load while the app loaded etc.. no go

then i tried to see if i could add a progress bar on top of the module loading 
so the user is at least informed but to my dismay it loads too fast for the 
progress bar to show up

heres the size of the swif being loaded
364K 2009-04-23 13:54 nutrition.swf

the images and other swfs that load into this module are about 1-2 megs total. 

If i avoid using modules it loads on localhost almost instantly :(

I have a feeling the source = for images and swf loading is whats dragging it 
to load fast.


What options do i have for either preloading quicker for this module?
Is it possible that my custom component is causing this performance issue?

[flexcoders] Popups and accessibility (JAWS)

2009-04-23 Thread KOVÁCS István

Dear All,

I've been assigned the task of testing and fixing accessibility tasks in a Flex 
3 application. One of the problems we're having is JAWS not reading popup 
windows. The Alert control works (when the alert pops up, title, message are 
read, focus is on the default button, and the default button's label is also 
read, all without any user intervention, e.g. moving focus with TAB). However, 
popup windows created in other ways (e.g. the sample at 
http://livedocs.adobe.com/flex/3/langref/mx/containers/TitleWindow.html) do 
not: the popup is shown, but JAWS does not read anything.

Are we doing something wrong, is there some special setting that we need (or 
perhaps JAWS treats Alert in a special way)? We have a popup window component 
that handles user confirmations, having a configurable number of buttons, a 
title and a text message. I've tried setting focus (setFocus() and 
drawFocus(true)) on the window or the Label component used to display the 
message, and it's OK on the screen but JAWS does not read anything.

Thanks in advance,
IstvÃ¡n

 I have the book now. I am trying to make it work and I am almost there, but
 the sprite is only glides correctly when thrown if I drag from top right to
 lower left or lower left to top right.

 If I throw it directly to the right it moves up and if I throw it to
 directly to the left it goes down. If I throw it up it goes to the right.
 And if I throw it down it moves to the left.

 Here is the code (_object is the sprite being throw):

 if(_drag == true){

 var diffx:Number = initX - mx;
 var diffy:Number = initY - my;

 var speed:Number = 12;
 var angle:Number = Math.atan2( diffx, diffy );
 //var radians:Number = deg2rad(angle);
 var xVel:Number = Math.cos(angle) * speed;
 var yVel:Number = Math.sin(angle) * speed;

 function deg2rad(deg:Number):Number {
 return deg * (Math.PI/180);
 }

 function onLoop(evt:Event):void {
 _object.x += xVel;
 _object.y += yVel;

 xVel *= 0.9;
 yVel *= 0.9;

 if (xVel  0.05  yVel  0.05) {
 _drag = false;
 _stage.removeEventListener(Event.ENTER_FRAME, onLoop, false);
 }

 }

  Generate your columns as you are, you said that was working.  But you
 still have to give the datagrid the data.  How/are you doing that?  Note, do
 not use XMLList if you are binding.

  Hi Tracy,

 Thanks for writing back. I did assign the XMLList to a variable and I could
 assign that variable to the datagrid.

 However, since I have to create datadrigcolumns dynamically, wouldn't that
 not work right? In assigning the variable to the datagrid without any other
 work I would have to specify the number of columns that it fills no?

[flexcoders] VIEWSTACK question.

2009-04-23 Thread sailorsea21

Hi everyone, I have a question on viewstacks.

I have my viewstack created on MXML with the main canvas also created in MXML.

something like:
mx:Viewstack id='myViewstack' creationPolicy='all' 
initialize='getOtherCanvases()'
mx:Canvas id='mainCanvas'/
/mx:Viewstack

At initialize I call 'getOtherCanvases' function, which adds additional 
canvases to 'myViewstack' depending on the result I receive from my DB.

My question: When I switch viewstack Index, the content of the canvas wasn't 
previously created and all the children jitter in place the first time I load 
each index. Shouldn't the creationPolicy='all' create all the children of the 
viewstack? 

How can I achieve this?

If I create the viewstack and main canvas in actionscript, will it solve my 
problem?

Thanks everyone. :)

[flexcoders] Setting dateField.SelectedDate when component is disabled?

2009-04-23 Thread Mic

In a modal View state the dateFields are disabled but I need to populate them 
for the current record. I can stick my proc values in when they are enabled, 
but not when disabled. I tried

dtCmplxStartDate.enabled = true;
dtCmplxStartDate.selectedDate = tempStrtDt; 
dtCmplxStartDate.enabled = false;
dtCmplxEndDate.enabled = true;
dtCmplxEndDate.selectedDate = tempEndDt;
dtCmplxEndDate.enabled = false;

but no go. TIA,

Mic.

 I am trying, in MXML, to size a list to 100% of its container, but when I do,

 in the item renderer itself. Nothing.
 
 In a fixed size layout, i can set the rowcount but I want it to be fluid in 
 case the user resizes the window.
 
 Anyone know why a list wouldn't size by percent to fill a parent container?

Tim,

You're right! It does seem to make a difference how the series object is
instantiated. Odd.

I was headed down the path of creating the whole chart chart in AS. Thanks
