[flexcoders] Re: Push verse Poll in Flash Player
I think it's worth trying, because trying to read
an integer this way won't waste any CPU cycles -
Flash/Flex probably run select() or poll() internally
and just sleep - until anything arrives over the socket.
(Versus trying to pull anything every 30 seconds -
that will cost you CPU and also feel delayed).
And whenever an integer arrives, then you could
use that number to indicate how many records have
changed at your backend, so that you can use it to
provide feedback on the progress to the user
while fetching the updated data over HTTP.
Regards
Alex

[flexcoders] What's wrong in using itemRenderer ?
I'm trying to add itemRenderer like, but it doesn't work. However if I remove
the check it's adding the itemRenderer.
for each (var column:XML in columns)
{
var col:AdvancedDataGridColumn = new AdvancedDataGridColumn(column);
col.headertext=colu...@label;
if(column==status) {
col.itemRenderer = new ClassFactory(RenderCategory);

[flexcoders] Accessing Network Drive in AIR
I have created an AIR application that accesses files on the network drive. Each machine that is running the AIR app may have a different letter/drive mapped to the network drive. Therefore, in order to alleviate drive mapping issues, I wanted to simply use the absolute network path to the file(s), i.e. \\network-drive-location\department folder\config.xml However, that doesn't seem to work as it consistently throws an error. Is is possible to load files using this type of path or do I need to have a letter associated with the path, i.e. N:\network-drive-location\department folder\config.xml Thanks for the assistance.

[flexcoders] Re: Method for a Datagrid Button Itemrenderer
Hi Angelo,
You're close. You'll need to declare the event in the DataGrid. A
simple subclass should do the trick. This way you can add the event
listener in mxml too:
package myPackage
{
import mx.controls.DataGrid;
[Event( name=myTest, type=flash.events.Event )]
public class MyDataGrid extends DataGrid
{
}
}

Would it be possible to simply add it to the MXML file where I am declaring the
datagrid, instead of subclassing it?
Thanks.

Hi Angelo,
You're close. You'll need to declare the event in the DataGrid. A simple
subclass should do the trick. This way you can add the event listener in mxml
too:
package myPackage
{
import mx.controls.DataGrid;
[Event( name=myTest, type=flash.events.Event)]
public class MyDataGrid extends DataGrid
{
}
}

Hi Don,
Thanks for the reply.
I do am able to do the same using an in-line itemrenderer.
But right now, my itemrenderer is an external AS file.
So I declare my MXML like:
mx:DataGridColumn
id=dgActionColumn width=100 visible=true
itemRenderer=myButtonItemRenderer
/
Where myButtonItemRenderer is an external AS file which extends the button.
Now, where I declare the datagrid, I am writing a function which I need to
wire
up to the itemrenderer so that on the click of the button, that method is
dispatched.
Thanks.

Hi Flexcoders,
I have a datagrid and an button itemrenderer named btnRenderer.as

[flexcoders] Null object error on test for null
In the function below, I begin by testing to see if a particular object is
null (the array of ComboBoxes that represent the children of a Repeater,
which may or may not exist). The element is defined in MXML, though of
course it may be null.
But if it *is *null, a null object reference error is thrown. Could someone
please explain this for me? (SDK 3.5, by the way).
public function handleFilterChange():void{
if(filterCombo!=null){

[flexcoders] Re: Method for a Datagrid Button Itemrenderer
Not that I know of. You could avoid all of this by just listening for the
DataGrid's itemClick event. (mx.events.ListEvent) In the result handler you
could check if ( event.itemRenderer is btnRenderer ) { do your thing }

[flexcoders] Possible to filter data by Type for LineChart series?
All of the data examples I see for Flex charting are simply string months and
number attributes, but that doesn't mesh with normal query results. Let's say
this is my dataset from a query (returns all my withdrawals for the month).
//my data
var expensesAC:ArrayCollection = new ArrayCollection( [
{ date: 1/12/10, type: 'checking', Amount: 450 },
{ date: 1/13/10, type: 'savings', Amount: 600 },
{ date: 1/15/10, type: 'checking', Amount: 300 },
{ date: 1/19/10, type: 'savings', Amount: 900 },
{ date: 1/20/10, type: 'checking', Amount: 500 } ]);
I'd like to have a 2-line chart...1 line for checking and 1 line for savings,
but no lines appear. I tried implementing a dataFunction and debugging shows
it's returns values at the correct type, but that doesn't work (no lines
appear). Any ideas?
Here's the full mxml...if you remove the dataFunction attribute from the 2
LineSeries, then the map (as expected) draws both lines on top of each other.
Thanks in advance.

Ok. I have the following HTTP Service declared:

result=rdHandler(event);
fault=rpcFaultHandler(event);/
In the init() function (which is called when the 'show' event happens, because
the page it's on happens to be part of a ViewStack) I have the following line:
reportDataRPC.send();
This loads the data from the .xml file and in the rdHandler function lets me
put that data into my various ArrayCollections and whatnot... That's working
fine... At least, the FIRST time...
Every subsequent time, the result-set is exactly the same as the first time --
even if the .xml file it's reading has changed in the interim.
If I completely shut-down the program and re-load it, then I finally get the
new .xml file in there.
So, how do I get it to give me a complete refresh of the data? I've tried
calling 'reportDataRPC.clearResult()' and 'reportDataRPC.disconnect()' after
storing the data in my ArrayCollections, but that didn't seem to do anything at
all...
I'm at a complete loss -- it's totally unacceptable to not be able to get the
new data when the underlying .xml file changes. Can someone point me in the
right direction?

It might be getting cached. nbsp;Try adding a timestamp to the end of the url

Re: [flexcoders] HTTPService not updating...
it's prob accessing it from the cache.
instead of this,
url=reports/xml/{_reportInfo.fileName}.xml
use this:
url=reports/xml/{_reportInfo.fileName}.xml?time={getTimer()}
that snippet might not be bindable so add the time in code whenever you
access that file

Re: [flexcoders] How to get the width of the Itemrenderer in a List
Spark. If the item renderer item is outside of the Lists visible area then it returns width or height 0 or sometimes index out of bounds errors. It seems items aren't created if they haven't been scrolled into view yet and if they have but they aren't in view currently then I think it's returning width and height as 0. I've made sure to set useVirtualLayout false. s:HorizontalLayout useVirtualLayout=false/ I don't have the columnWidth or list height set but I have the ItemRenderer width and height set to 32.

So if the List is 105 px wide and an single itemrenderer is 10 pixels wide then I want to resize the list to 100 pixels so item 11 doesn't show. -- Alex Harui Flex SDK Team Adobe System, Inc. http://blogs.adobe.com/aharui

An XML node can never be equal to a string.

[flexcoders] Re: Null object error on test for null
Which line does the null pointer error occur on?
Not that this is you problem, but I always check for null when casting with
'as'.

In the function below, I begin by testing to see if a particular object is
null (the array of ComboBoxes that represent the children of a Repeater,
which may or may not exist). The element is defined in MXML, though of
course it may be null.
But if it *is *null, a null object reference error is thrown. Could someone
please explain this for me? (SDK 3.5, by the way).
public function handleFilterChange():void{
if(filterCombo!=null){
for(var i:int=0;ifilterCombo.length;i++){
for(var j:int=0;jfilterCombo[i].length;j++){
var cb:ComboBox = filterCombo[i][j] as
ComboBox;
cb.selectedItem=null;

Re: [flexcoders] Re: What's wrong in using itemRenderer ?
Hi Amy,
Thanks..
One more question , Is there any different rule to add itemrender on
categorized grids ? For example, Here is my sample code to for Hazard and
Status column ,
var col1:AdvancedDataGridColumn = new AdvancedDataGridColumn();
var col2:AdvancedDataGridColumn = new
AdvancedDataGridColumn();
//data for column 1
col1.headerText=Hazard
col1.dataField = hazard;
col1.itemRenderer = new RenderCategory();
cols.push(col1);
//data for column 2
col2.headerText=Status
col2.dataField = status;
col2.itemRenderer = new RenderCategory();
cols.push(col2);
But when I view my grid , It only applies to Status column ,

But if I remove grouping , rendering applies to both the columns . However,
Hazard is not a grouping field, There is another grouping field category .
