[flexcoders] Re: Could not resolve * to a component implementation.

2010-07-01 Thread turbo_vb

Glad that you were able to resolve the problem.  The AS file IS a class, and if 
it lives in the same package as the mxml component, the compiler will balk; 
because it doesn't know which one to import elsewhere.  Adobe best practice 
would have you use Uppercase for the first letter of all classes.  Renaming the 
script class to something like FooScript.as or FooModel.as might be a better 
way to go.

Cheers,

[flexcoders] flexTasks.jar for Flex 2.0

Hi All,

Is there a different flexTasks.jar for Flex 2.0 ? I am trying to build my

Re: [flexcoders] How to remove duplicate objects from an array of objects

2010-07-01 Thread Warren

Yup -- I'm using AMF.  

What you say makes good sense.  Using the bytearray coould be risky especially 
since I can't depend on the property order always being the same.  I haven't 
done much OO yet but I see your point about long term maintenance.  

The valueOf trick reminds me a lot of what I was doing with the 
ObjectUtil.toString().  As long as the objects were simple, I would get a clean 
consistent string.

Hmm -- Maybe using the dict object wasn't such a bad idea after all.  It was 
extremely simple and would probably do the trick in my environment.  I have a 
lot of control over user entry.  I'm using restrict on the input fields and 
doing additional cleanup in the backend as part of my oracle stored procs.  
There won't be odd characters in the data.

This is proving to be a good learning experience.  I haven't had to dig this 
deep into object comparison techniques.  I'm sure glad you have your act 
together and are willing to share.

  Well, then my take would be this: since you are sending them from CF, you are 
probably using AMF, and since you do so, you can use strongly typed objects, 
and (again, I'm not sure but...) I think that strongly typed objects are 
written accordingly to their describeType - this means objects are going to be 
consistent when serialized. But, the thing with comparing serialized objects is 
more of a trick, then a really good design. I would go for some kind of 
equals():Boolean method for those objects and implement it in a way it would 
only compare the relevant data.
  Something more like this:


  class BusinessObject {


  public function equals(object:BusinessObject):Boolean {
  if (this.foo != object.foo) return false;
  if (this.bar != object.bar) return false;
  return true;
  }
  }
  This would cover all the cases, like when you want the objects to have only 
some unique properties, but other you don't mind. It will be also easier to 
maintain in the long run. This is an inherent problem of OO languages vs 
rrelational database languages, where the first implies that objects must have 
unique identity and the second believes that the objects that have all the same 
traits are the same. Of course this is not black and white, but it's a known 
problem. The equals-like method is probably the standard kind of solution to 
this problem, unless you can find some more optimized way to do it.
  There are more interesting things, for example, if you implement valueOf() 
method of an object in a way that it returns number or string, the implementors 
may be treated under certain circumstances as being of simple type, so, say and 
you have something like this:


  class BusinessObject {


  public function valueOf():Object {
  return int(this.foo + this.bar);
  }
  }
  Then you can cast BusinessObject to int and compare ints :)


  var bo0:BusinessObject = new BusinessObject(100, 200);
  var bo1:BusinessObject = new BusinessObject(100, 300);


  if (int(bo0) === int(bo1)) // objects are assumed equal. 


  This approach may be more efficient if you cache the valueOf value in the 
BusinessObject so that when called it only returns the value.

[flexcoders] getting added values out of a combobox

2010-07-01 Thread Andrew

Hi:
My form has a number of fields, and I use the Change event to trigger event 
handlers to see whether enough fields have been populated that I should enable 
the Submit button.

I am using a combobox for one of the fields, so users can type in a value if I 
have not included it in the list. However, how do I get a typed-in value back 
out again? When the user types in a value rather than selecting an existing 
one, the change handler does not recognize that the combobox's selectedIndex is 
> -1, and there does not seem to be a label field I can check (if != null && != 
''). The example in Tour de Flex is not illuminating, for it only shows adding 
a value to a combo box, not doing anything with the value afterwards.

Thanks in advance for your help.

Re: [flexcoders] How to remove duplicate objects from an array of objects

2010-07-01 Thread Warren

well isn't that interesting.  Wonder why that is.  I wish things were 
consistent.

I guess I could normalize things by looping over the array and creating a new 
array array of literal objects.

What I have is an array of objects coming from a cold fusion query so those 
objects will be consistent.  My Flex users will be adding to and subtracting 
objects from it.  .  I'll be creating new objects on the fly so I should be 
able to create the objects the same way (maybe use a simple class) and get 
things right.

I really like the idea of using the bytearray -- i hate the idea of flattening 
the objects into strings.  Too many things can go wrong with that

I think I found the answer in "myComponent.skin". i wish there was a
skin properties object on UIComponents. if i want to set a property in
a skin there's no way to do that without extending the component and
adding the property to the subclass. it's not a far fetched idea. in
HTML there is a style attribute that accepts an object literal, for
example:

normally you would want to separate the view from the model etc but
with skins it's a new type of view. some properties pass from the host
component to the skin. if you're making your own skins you're probably
having to add custom properties.

Re: [flexcoders] Multiple instances of a module with different styles

Basicallly, you can’t do exactly that because you are still trying to use type 
selectors (Button is a type selector).  Also, I don’t think you can load two 
CSS style SWFs with the same selector name/path.

One thing you can do is to define class selectors in each style module with a 
computable prefix like:

.style1Button
{
color: red;
}

.style2Button
{
color: green;
}

Then assign the selectors or calculate the styleName property as needed.

Hi Alex,

ok it's clear with the factory. But how can I handle the following scenario

Module 'MyModule':
* Module has a button with style name 'myButton'
* Module gets a url for a style file from main application and loads it with 
styleManager.loadStyleDeclarations(mystyle)

Application:
* Creates ModuleLoader 1 with url 'MyModule.swf' and pass it style url 
'style1.swf' which defines 'Button.myButton' with text color red
* Creates ModuleLoader 2 with url 'MyModule.swf' and pass it style url

I want to have one module with red text and the other with green text. What I'm

Are you expecting the datagrid to sort when first shown or when you click on

To sort when first shown you will need a creation complete function where you 
would create a new sort and refresh.

Re: [flexcoders] how to filter our a column in datagrid?

Filtering a copy of the ArrayCollection and set the dataProvider to that 
filtered copy is one way.

Re: [flexcoders] Multiple instances of a module with different styles

2010-07-01 Thread Haykel BEN JEMIA

Hi Alex,

ok it's clear with the factory. But how can I handle the following scenario
with class selectors :

Module 'MyModule':
* Module has a button with style name 'myButton'
* Module gets a url for a style file from main application and loads it with
styleManager.loadStyleDeclarations(mystyle)

Application:
* Creates ModuleLoader 1 with url 'MyModule.swf' and pass it style url
'style1.swf' which defines 'Button.myButton' with text color red
* Creates ModuleLoader 2 with url 'MyModule.swf' and pass it style url
'style2.swf' which defines 'Button.myButton' with text color green

I want to have one module with red text and the other with green text. What
I'm getting now is that both use sometimes one color and sometimes the
other, I think depending on which styles are loaded first.

Thanks,

Haykel Ben Jemia

This routine is very sweet.  And very clever.  So much better than using the 
objectUtil and Dict concept. 

Oleg, I can't thank you enough.  I never would have went down this path.  I 
really appreciate the code and especially the insight into a different method..

A module is a factory for multiple instances of a class(es).  Type selectors 
map to a class.

Per-instance styles are often done with class selectors via the styleName 
property

[flexcoders] Multiple instances of a module with different styles

2010-07-01 Thread Haykel BEN JEMIA

Hi,

I have a Flex 4 application that loads modules dynamically. The modules load
style files dynamically based on their configuration files, so that every
module can load different style files. If multiple instances of a module are
created (with multiple ModuleLoader instances having the same url),
everytime an instance loads a style file, it gets also applied (partially)
to the other instances so that all instances end up with mixed styles.

I originally thought that the per-module styles feature of Flex 4 should
allow every module to apply its own styles, but it seems like it's more a
"per-module-type style".

Is there any way to load styles "per module instance"?

Re: [flexcoders] Re: Could not resolve * to a component implementation.

2010-07-01 Thread Brian J. Ackermann

Here's what the problem was.

I had originally had a file called "Foo.mxml" which contained a lot of
ActionScript Code.  I decided to create a new ActionScript FILE to contain
that script code.  I named the file "Foo.as", to indicate the correlation
with the mxml file.

Renaming this new as file to "foo.as" (lowercase f), resolves the issue.

I'm not at all sure why this would have caused a conflict with the compiler,
since it wasn't a classbut at least I've resolved the issue.

You can do pretty well with only two ByteArrays,

var ba1:ByteArray = new ByteArray();
var len:int;
var tail:int;

for ( ... )
{
ba0.writeObject( ... );
ba1.writeObject( ... );
if (ba0.length !== ba1.length) // objects are different
len = (ba0.length >>> 2) << 2;
while (ba0.position < len)
{
if (ba0.readUnsignedInt() !== ba1.readUnsignedInt()) // objects are
different
}
while (ba0.bytesAvailable)
{
if (ba0.readUnsignedByte() !== ba0.readUnsignedByte()) // objects
are different
}
}

Or something along those lines.

  If those are simple dynamic objects you can write them to ByteArray and 
compare them, it will be faster than using ObjectUtils.
  Everything in AS, except for numeric types (but not Date), strings and 
booleans are references, Array.indexOf() uses strict equality (compares 
references), so even if there will be 1 and "1" indexOf will not treat them as 
same. But, most of the time this is what you want :)
  There's also Array.filter method, but it's slower then a simple loop. But may 
look somewhat prettier :)

nope -- problem is that indexOf, contains, etc is not matching the object

  You may not get what you want with toString() and is not needed if checking 
for duplicate references.

Are you expecting the datagrid to sort when first shown or when you click on 
the column header? The code you have will only be called when you click on the 
column header.

To sort when first shown you will need a creation complete function where you 
would create a new sort and refresh.

One other thing to check. Make sure you are not using a reserved name for your

[flexcoders] datagrid column sorting

2010-07-01 Thread Scott

Take this scenario:

 

.

 

[Bindable] public var acAppts:ArrayCollection = new ArrayCollection();

 

private function sortDate(itemA:Object, itemB:Object):int 

{

return ObjectUtil.dateCompare( itemA.dtCreated,itemB.dtCreated);

}

 

 

...

 



  

  



   



 

 

I should be sorting on the dtCreated field which is a date.  However,
it's not occurring.  If I set a breakpoint on the sortDate function, it
never gets hit.

 

I'm not sure if the reason is because the parent component populates the
acAppts which doesn't cause a trigger for the dataGrid to run the sort
function or what.  Anyone have an idea on what is going on with this?

Thanks Akshar, but don't I need a click event on the checkbox to update the 
dataprovider? The problem is adding a click event to a dynamic checkbox in the

Re: [flexcoders] Re: httpservice.lastresult completes but theres no data.

2010-07-01 Thread Oleg Sivokon

E4X always reduces the  kind of nodes to  because first is
redundant and ambiguous. It is not clear whether the first kind is in fact
two nodes - an element node with a child text node with the value of empty
string, or is it a single element node. It is also longer than needed, if it
is meant to be a single node.

Well, the result was not missing, it's just that the way you printed it out
was not good. XML.toString() prints the value of the node, not the
structure. The value of the self closing node is "". However, toString()
makes an exception if the node to be printed is the root node, it will print
the structure of the node. I don't know what is the reason behind it.

Re: [flexcoders] Re: httpservice.lastresult completes but theres no data.

2010-07-01 Thread Clark Stevenson

Thanks for your help Oleg, Appreciated.

I think your solution makes sense although i think i also may have been
uneducated with the root node.

The server returns  as 

And since data is the root node, it appears to be ignored (or an empty
string like you say).

will turn into

And this solved the problem of the missing lastresult.

[flexcoders] New Datagrid announced...

2010-07-01 Thread Gregor Kiddie

Deepa announced that the Spark version of the Datagrid would be in Hero.

 

Are we talking a direct replacement for the MX Datagrid, or the ADG?

 

Let's hope it's more a direct replacement rather than redoing the ADG...
that really was rubbish.

 

Saying that, what additional feature are people looking for in a new
version of the Datagrid?

 

Gk.

RE: [flexcoders] TimeZone issue

2010-07-01 Thread Keith Reinfeld

Ivan, 

 

> Is there any way we can get the Timezone selected by the user in the
operating system from running Flex application? 

The short answer is no.

 

> 720 minutes after UTC can mean "Auckland, Wellington" or "Fiji" 

 

The above is only true when "Auckland, Wellington" is not on Daylight Saving
Time (DST,) -- since "Fiji" does not observe DST, and that, I suspect, is
the real issue. 

You can use getTimezoneOffset() to calculate many of the DST details of the
client machine. For example: 

 

 

*/

// Test for local DST

public function hasLocalDST():Boolean{

var y:Number = new
Date().getFullYear();

var s:Number = new Date(y,
0).getTimezoneOffset();

var e:Number = new Date(y,
5).getTimezoneOffset();

if(s != e){

// DST is
observed

return true;

}else{

// DST is
not observed

return
false;

}

}

 

Similarly, for locales that observe DST, you can work out exactly when DST
starts and ends, whether the locale is in the Northern or Southern
hemisphere, and whether the locale is currently on DST. All assuming, of
course, that the client machine's time settings are correct for the locale.

E4X prints the content of self closing nodes as an empty string (if it's not
the root node). You may want to use toXMLString() to print the structure of
the node.

It seems e4x is the problem.

If i change the httpservice class to "xml"

The lastResult property is shown.

There must be some special rule where this isnt acceptably in e4x:



It only shows under the xml format.

Why is this?

I really appreciate for your response. At least I see some hope to get the 
issue resolved. I saw very interesting articles on your blog but i would 
appreciate, if you can direct me to look at specific example related to my 
issue.

I just changed creationComplete to dataChange and immediately started seeing 
lot of null object reference issue as it refers to TextInput which is 
initialized by {data.col1} and that value is used thruout the application for 
various other processing.

Thanx and Regards
