[flexcoders] Grouping and ItemRendering issue

[RishiShahi]

I've applied itemRenderer on advance datagrid column. Here is my code
snippet,

http://old.nabble.com/file/p29303190/3.png 

Now problem is that when my grid loads ( default it loads with group by on
'Category' ) , When grid loads only "Status" column is rendered not the
"Hazard" column . See below, 

http://old.nabble.com/file/p29303190/2.png 

However, When I uncheck the "Group By" checkbox which removes the grouping ,
Hazard column gets rendered . 

http://old.nabble.com/file/p29303190/4.png 

But funny thing is that it only renders one item , and once I use horizontal
scroll bar in data grid to scroll down , all hazard column gets rendered
automatically . Why is such effect ?

Here is my hazard rendering code ,

Re: [flexcoders] Alex Hauri Sample | CheckBox DataGrid

[Alex Harui]

Did you add some sort of double-click logic to the DG?  The basic example only 
uses single click for selection.  The selectionIndices should change and then 
the checkbox renderer should call isItemSelected and check the box if needed.

The profiler will show you who is still referencing the object.

Does simply nulling the parent effectively mark the embedded object(s) for GC,

[flexcoders] Single Sign on with Flex/BlazeDS

[Dharmendra]

Hi All, 
Does blazeDS supports single sign on functionality ? As far as I know 
SSO has not much to do with BlazeDS rather it has more to do with the 
application server where the Application has been deployed and Browser who is 
accessing the application. I am using blazeDS 3.2 , websphere and  LDAP.
 
Please provide some pointers on this.

Thanks,
Dharmendra

Re: [flexcoders] How to split a String on spaces but including Quoted Phrases?

[Oleg Sivokon]

Ouch, actually, it has a flaw, but I'm not sure you need a fix for that, but
it's possible to fix it, if you want. It only checks for the double quotes,
when it checks for the non-quoted words, but it checks for both single and
double quoted groups of words. If you need both single and double quotes
however, the expression is going to be a tid bit longer... but if you don't
need, then it'd be shorter in fact:

/(".*[^"]")|(\s[^\s"]+(?!\s"))/g

Try doing something like this in your itemRenderer, and see if it works:

private var _widthChanged:Boolean;
private var _newWidth:int;

override public function set explicitWidth(value:int):void {
super.explicitWidth = value;
_widthChanged = true;
_newWidth = value;
invalidateProperties();
}

override protected function commitProperties():void {
if (_widthChanged) {
width = _newWidth;
_widthChanged= false;
//if the itemRender is not actually a Text control,
//but instead the text control is a child
theTextControl.validateNow();
}
super.commitProperties();
}

If that doesn't work, try checking the text of the control and look at its 
internal text field and how big it thinks it is.  You should be able to see 
these values in the debugger if you set a break point, even if the variables 
are not exposed (I think you may need to turn something on from the menu of the 
variables window to enable this).

Re: [flexcoders] How to split a String on spaces but including Quoted Phrases?

[Oleg Sivokon]

Sorry to chum in :)

Re: [flexcoders] garbage collection question

[Oleg Sivokon]

1. Using weak references is the last thing you should do, whenever possible
you should avoid it. By doing so you leave all means of control of the
object, and if the object has some kind of behavior that will keep it
"alive", you won't be able to delete it ever (example, the *deleted* object
did not close LocalConnection).
It is not possible to conclude from what you describe whether objects will
be removed or not. The objects will be removed when there will be no
reference to the "roots". "Roots" are local variables, or field
initializers. These are either persistent or temporary, local variables
would be an example of temporary "roots".
Imagine this life span of an object:

public var persistent:Object;
public var anotherProperty:Object;
public var revealPresense:Dictionary = new Dictionary(true);

public function DocumentClass()
{
super();
var temporary:Object = new Object(); // the object created, put into the
heap, bound to the temporary toot
persistent = temporary; // the object is in heap, now referenced by two
variables.
} // temporary variable is destroyed, now the object is only referenced by
persistent root.

public function anotherMethod():void
{
anotherProperty = persistent; // the object is still in heap, but now
has two persistent roots.
persistent = null; // the object is still not eligible for GC, it is
referenced by persistent root.
revealPresense[anotherProperty] = true; // let's store a weak reference
and observe the object deletion.
anotherProperty = null; // the object is no longer referenced, but may
exist for some time.
for (var obj:Object in revealPresense) trace( obj ); // it may be still
here...
setInterval(checkPresense, 1);
}

public function checkPresense():void
{
for (var obj:Object in revealPresense) trace( obj ); // it may be still
here...
}

RE: [flexcoders] How to split a String on spaces but including Quoted Phrases?

[Keith Reinfeld]

Nick, 

 

I think this satisfies your conditions. There is a for-loop but it's not
iterating over the entire string, which, I'm certain, is what you wanted to
avoid. 

 

var myString:String = 'flex "action script" parse string function'; 

var resultArr:Array = regExpDQ(myString, false); 

trace("resultArr = ",resultArr); 

 

function regExpDQ(s:String, includeQuotes:Boolean):Array { 

var re:RegExp = /".*?"/g; 

// get string segments contained in double-quotes  

var matchArr:Array = s.match(re); 

// strip out string segments contained in double-quotes 

s = s.split(re).join(''); 

// put the remaining string segments into an array  

var arr:Array = s.split(' '); 

// merge the two arrays  

var len:uint = arr.length; 

var a:Array = []; 

var j:uint = 0; 

for(var i:uint = 0; i < len; i++) { 

if(arr[i] != ""){ 

a[i] = arr[i]; 

}else{ 

if(includeQuotes){ 

a[i] =
matchArr[j++]; 

}else{ 

a[i] =
matchArr[j++].split('"').join(""); 

} 

} 

} 

return a; 

}

Hi,

I haven't been able to work out regex yet so apart from looping and parsing
a string manually, is there anyway of parsing the following string...

flex "action script" parse string function

into the following Array...

[0] = flex
[1] = action script
[2] = parse
[3] = string
[4] = function

[flexcoders] ActionScript dispatchEvent silently fails with ‘Asynchronous viewer update’ mess

[tntomek]

I'm manually dispatching a propertyChanged event from my model only to never 
have it be caught. When I try to debug and step into (F5) the dispatchEvent 
call I get FlashBuilder error "Asynchronous viewer update" displayed twice.

Does anyone have an idea why this might be failing? Possibly cyclical 
references? I have tried using weakReferences and same result.

Note that this dispatchEvent works perfectly when dispatching some other 'Row' 
in my model by only fails in this odd scenario where my Row is nested in 
another object.

The basic use case is for a launcher application. It launches and manages
other applications at user request, however doesn't need to install the
