[flexcoders] LCDS 2.6 Clustering Problem
We are trying to get clustering configured for our application so that jms topic messages will be handled properly by the servers in the cluster. We are using a hardware load balancer. We have set up a default-cluster, using tcp and set the cluster-message-routing property to server-to-server. We see subscription messages being broadcast and received between the servers in the cluster. From the server you subscribe to: 2009-06-30 17:49:01,248 INFO [STDOUT] [Flex] Sending subscription to peers for subscribe? false selector: login='john' or systemwide='true' subtopic: null and on the other server: 2009-06-30 17:49:01,989 INFO [STDOUT] [Flex] Received subscription from peer: 10.230.3.4:7800 subscribe? true selector: login='john' or systemwide='true' subtopic: null The issue is that messages posted to the jms topic don't seem to get sent to the other servers in the cluster. If you are connected to the server handling the message you will receive it, otherwise nothing. Also there is nothing in the logs indicating the topic messages are being sent to the other servers. Any thoughts on what may be wrong?

[flexcoders] Problem with DataGrid ItemRenderer
We have a datagrid that is using an item renderer that consists of an
HBox implementing IDropInListItemRenderer with a few components in
it. One of these components is a Text component used so some text
can be wrapped.
The problem is there are a few cases were the datagrid does not seem
to size the cell properly to the item renderer. The easiest case to
demonstrate is sorting the datagrid. The datagrid renders fine when
first loaded but if a column is sorted the row heights no longer are
variable, they are all the same height. Is there something else that
needs to be in the item renderer?
Here's some simplified code that demonstrates the problem (run it,
then sort the columns to see the issue):
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
mx:Script
![CDATA[
import mx.collections.ArrayCollection;
[Bindable]
private var dataSet:ArrayCollection = new
ArrayCollection([{item:1, text:Some text},
{item:2, text:Some
really long text that should wrap.}]);
]]
/mx:Script
mx:DataGrid dataProvider={dataSet}
variableRowHeight=true width=200
mx:columns
mx:DataGridColumn dataField=item/
mx:DataGridColumn dataField=text
itemRenderer=MyRenderer/
/mx:columns
/mx:DataGrid
/mx:Application
?xml version=1.0 encoding=utf-8?
mx:HBox xmlns:mx=http://www.adobe.com/2006/mxml;
implements=mx.controls.listClasses.IDropInListItemRenderer
mx:Text id=myText width=100%/
mx:Script
![CDATA[
import
mx.controls.dataGridClasses.DataGridListData;
import mx.controls.listClasses.BaseListData;
import mx.events.FlexEvent;
[Bindable(dataChange)]
private var _listData:BaseListData;
public function get listData():BaseListData
{
return _listData;
}
public function set listData
(value:BaseListData):void
{
_listData = value;
dispatchEvent(new FlexEvent
(FlexEvent.DATA_CHANGE));
}
override protected function updateDisplayList
(w:Number, h:Number):void
{
super.updateDisplayList(w, h);
if (data != null )
{
var ld:DataGridListData =
DataGridListData(_listData);
myText.text = ld.label;
}
}
]]

My question is: How in the world do I specify a custom itemRenderer
through Actionscript? With MXML you can do it like this:
LineSeries yField=costs
itemRenderer=mx.charts.renderers.DiamondItemRenderer/
But I'm not defining my LineSeries that way. I saw the demo of the
charting stuff over at QuietlyScheming.com
(http://demo.quietlyscheming.com/ChartSampler/app.html) but he's
also
defining the series at design-time.
Any thoughts?
Thanks in advance for any help that somebody can provide.
Cheers,

You're tripping over some of the conversion rules AS3 has

The bug has been logged, but if you want to work around it in the

stripped out of the data set.
i.e., turn soemthing like this:

[flexcoders] Re: Problems with tree selectedNode - Flex 2
Thanks Matt.
Few more things I found recently:
1. If you drag a node that has been set using selectedNode and you
try something like this in a dragEnter handler:
var treeItems:Array = event.dragSource.dataForFormat(treeItems) as
Array;
you get a 'null has no properties error'.
2. If enabled is set to false on the tree it still dispatches
itemClicks.
3. If you create a TextInput with enabled=false and then set it
to true later it becomes enabled but retains the
disabledBackgroundColor.

Subject: [flexcoders] Problems with tree selectedNode - Flex 2
I'm seeing some odd behavior when using the selectedNode property
of
the tree to return to a node in a tree or it's quite possible that
I'm not using it correctly.
The first issue is that if there are identical nodes in different
branchs of the tree visible setting selectedNode will just go the
first node. Run the example code below, but first open the 'dir1'
branch before clicking the button to see this behavior, it works
as
expected if the 'dir1' branch is closed.
The second thing is that when selectedNode is set and another
element of the tree is selected the selectedNode remains
highlighted
until you mouse over it.

[flexcoders] Re: Tree itemRenderer - flex 2
I have tried extending the TreeItemRenderer class similar to your
example, the problem that I have is that the item is still rendered
by a single label. It's not clear to me how I can create a more
complex item renderer, for example, one that consists of a label and
an image.
Is there a way to do this in flex 2 short of writing a custom
renderer that handles it's own indentation and controls?
Thanks.

You cannot just drop in any renderer for a Tree component or Menu
which
need to deal with indentation because your renderer doesn't know
anything about it. Instead, the easiest thing to do is to use an

example of a Tree item renderer. The renderer will change the font
weight and color of parent nodes and add text as to how many
children
each node has.

[flexcoders] Problem with DateChooser selectedDate - flex 2
If the selectedDate of a DateChooser is set to a date that is created
using new Date() with no arguments (or any similar constructor to get
the current date/time), the selectedDate is not highlighted on the
DateChooser when showToday is false.
Interestingly, it works if the date created using new Date(2006,2,15),
but I would just like to highlight today's date whatever that is.
Here's an example:
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.macromedia.com/2005/mxml;
xmlns=*
mx:DateChooser showToday=false selectedDate={now}/

[flexcoders] Re: Prob]lem with wordwrap - flex 1.5
Thanks for the response. Same behavior when setting the width of the column, as long as the column is narrow enough to cause the contents of the cell to take up more vertical space than the height of a grid row. Basically as soon as you click the scroll arrow the column keeps resizing itself (with no additional user input) until it disappears. Also, if there are multiple rows like this as you scroll down the grid it jumps to the top of each row so some content in the cell is never displayed. This is partly fixed in 2.0 in that the column no longer resizes itself, but there is still content in the cell that is never displayed. --- In flexcoders@yahoogroups.com, Matt Chotin [EMAIL PROTECTED] wrote: What happens if you hard-code the column width for the word- wrapping column? -Original Message- From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of pasflex Sent: Tuesday, March 07, 2006 1:34 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Prob]lem with wordwrap - flex 1.5 I have a datagrid that has wordwrap turned on for one of it's columns.

[flexcoders] Re: Problem dynamically creating text controls
Matt,
Thanks for the semi-useful suggestion ;)
Tried to set creationPolicy=all on the view stack and it has the
same behavior. For kicks, I also tried moving the call to
initLayout to the creationComplete event on the second VBox, this
did not help either. Any other ideas?
