[flexcoders] DSErrorHint
Hi to All, We are currently developing an Image Gallery Application. We have a fluorine service as our gateway to .Net. The developed application is working for a few weeks now, until today we encountered an error regarding the DSErrorHint, I've got some ideas about it but still can't figure it out how to trace the bug and solved it. Here is the specific error message: ReferenceError: Error #1069: Property DSErrorHint not found on String and there is no default value. at mx.rpc::AsyncRequest/acknowledge() at ::NetConnectionMessageResponder/NetConnectionChannel.as$40:NetConnectionMess ageResponder::resultHandler() at mx.messaging::MessageResponder/result() I will appreciate any suggestions and comments. Thanks, Romeo
[flexcoders] ItemEditors and ItemRenderers (was Re: Datagrid tab order?)
Can you check my sample here: http://roytang.net/sandbox/DataGridSample.swf Source at http://roytang.net/sandbox/DataGridSample.mxml When I tab starting from the textinput and all the way to the last row of the datagrid (row 14), it's still ok. But after tabbing out from row 14 the tab order becomes trapped in the onscreen checkboxes (and doesn't even follow them in the top-to-bottom left-to-right order) --- In flexcoders@yahoogroups.com, Alex Harui [EMAIL PROTECTED] wrote: tabEnabled is ignored for renderers/editors.

I appreciate the replies esp. since I can't provide my app's sample code here so I guess it's difficult for others to figure out. I guess the problem is I tried to avoid using itemEditors entirely and used itemRenderers instead, so now the tab order is all messed up and doesn't scroll. I'm going to try using itemEditors again. However, the main problem there is that I want to render the column as a checkbox and have it editable as a checkbox also. So I'll do the ff: 1. set itemRenderer=checkbox and itemEditor=checkbox. 2. set tabEnabled=false for the checkbox itemRenderer; this is so that the itemRenderers don't screw up the tab order Under the above setup, the tab order seems correct. The only issue with the above that I'm not sure how to support is that visually the column is a checkbox, but requires the user to click twice on the checkbox to toggle the value (once to enable edit mode, second time to actually edit). Is there any way to avoid this? Most of the examples of using checkbox as an itemEditor seem to use static text as the renderer. --- In flexcoders@yahoogroups.com mailto:flexcoders%40yahoogroups.com , Alex Harui aharui@ wrote: the default editing code handles offscreen rows. you can probably override focusinhandler and set editeditemposition the dg remembers the last position of the editor and restores editing there From: flexcoders@yahoogroups.com mailto:flexcoders%40yahoogroups.com [mailto:flexcoders@yahoogroups.com mailto:flexcoders%40yahoogroups.com ] On Behalf Of Stephen Roy J.

We had trouble before with having both an item renderer and an item editor for a column (which we need to have that checkbox column), so instead what I tried was simply having only itemrenderers for the controls (and updating the data on change of the itemrenderer controls) This seems to fix the default tab order, but there are still some issues with the tab order, namely: 1. Tabbing through the grid only traverses visible rows - how can a user navigate to scrolled-out rows using the keyboard? 2. Sorting the grid doesn't seem to sort the taborder - the rows are still traversed in the original order. (Strangely, reassigning a headerRenderer after the sorting sets the correct tab order - I found this by accident) 3. Tabbing into the grid from an outside control - looks like it remembers where the grid was last traversed and starts over from there. Is it possible to change it to always enter the grid from the first row? 4. I'm not sure of the behavior exactly, as I couldn't replicate it all the time, but tabbing into the grid after it has been mouse-scrolled seems to cause it to enter at different rows. --- In flexcoders@yahoogroups.com mailto:flexcoders%40yahoogroups.com mailto:flexcoders%40yahoogroups.com , Alex Harui aharui@ wrote: Sounds like editable!=true, so the DG's tab handling code isn't running.

[flexcoders] Re: getElement from scope
Like if i create a mx:TextInput id=foo / to work with it on the actionscript just use foo.text = 'bla' for example. The reason you can access foo in your AS here is because when you define an mxml-tag, it basically becomes a public, bindable property of that class. So if you want the same in AS it's sth like: [Bindable] public var foo:TextInput; So, looking at this code and suppose that you CAN NOT change not one line of this code, how do i work with foo in the myTimer function? If we CAN NOT change the code, there's no way to work with 'foo' in myTimer function (however as you pointed out yourself, you can test on the last part of childName of the last canvas to see if it matches the name of 'foo'). This is because you've declared foo inside the init-funtion, therefore it doesn't 'exists' out of the scope of that function. The thing is i'm creating a lot of forms dynamically Great :) So do I, and I stumbled on a likewise problem. Not being able to reference the created objects. Even if you think to outsmart Flex and do like JJain said (object.id='myId'), the object won't be accessible by the use of that ID. The reason is that Flex/Flash generates the id of a generated object itself. There is a clean workaround for this problem using a Dictionary with the id's as keys and the objects as values. You can find an explanation about this method here: http://www.jumpingbean.co.za/blogs/mark/flex_reference_components_dynamic_runtime_creation --Johan

[flexcoders] Achieving weak-ref VALUE Dictionaries; Alternatives
Hi all, I have a situation where I need to pool a certain type of objects based on their value, so that for each for each person ID I have at most one PersonVO living at a certain moment This way I can always test equality as follows: personVO1 === personVO2 instead of a custom value based method: personVO1.equals( personVO2 ) The most obvious way of achieving this is to use Factory backed by a dictionary or hashmap using personID as key. The problem is that, after some time, I can potentially deal with tens of thousands of cummulative distinct persons, but each one is used only for a couple of minutes and won't occur again. Having each instance referenced by a hashmap will only result in an inevitable memory leak. So, basically, what I need is a dictionary with weak *references* instead of keys... I thought about using one dictionary in the middle and store the PersonVO instance as key ( pseudocode ) to store var tempDictionary:Dictionary = new Dictionary( true ); tempDictionary[ personVO ] = true; personIDToPersonVOMap[ personID ] = tempDictionary; to retrieve for ( var personVO:PersonVO in personIDToPersonVOMap[ personID ] ) return personVO; // if for loop does't hit any key then the value object was garbage collected, and I can create a new one This should, in theory, work... at the expense of some obvious overhead ( one new Dictionary instance per value object ). A second approach I was thinking about is not so straightforward but might perform better: - Use a normal hashmap to store the value objects - Every now and then, create a dictionary with weak keys and put all the value objects as KEYS - delete the hashmap - wait for GC to run - after some time, or on demand, iterate over the keys ( that were not GCCollected ) and repopulate the hashmap Of course the latter approach will only work if the GC runs during the no-hashmap interval. Is there any way to fire the GC manually? ( creating a zillion empty objects perhaps ) Any ideas? Thanks, Aldo -- Aldo Bucchi +1 858 539 6986 +56 9 8429 8300 +56 9 7623 8653 skype:aldo.bucchi

Hi,
I know this problem, happened to me once.
This is a known issue that won't be fixed by Adobe.
It usually happens when you try to scroll - the data is presented in
a wrong way.
But it has a solution.
Add an event listener for FlexEvent.DataChange in your itemRenderer.
In the listener function do your code again.
for instance if i have an inline item renderer that presents a
property named currentConcurrentCalls, i need to add an event
listener for the dataChange event and render it again there :
mx:itemRenderer
mx:Component
mx:HBox width=100% creationComplete=doInit()
mx:Script
![CDATA[
import mx.events.FlexEvent;
import mx.resources.ResourceBundle;
[ResourceBundle(hostlynx)]
private static const _rb:ResourceBundle;
[Bindable]
private var strMaxConcurrentCalls:String;
private function doInit():void{
if(data!=null data.entityObject
[currentConcurrentCalls] != null){
strMaxConcurrentCalls =
data.entityObject.currentConcurrentCalls;
}
addEventListener(FlexEvent.DATA_CHANGE,dataChange);
}
private function dataChange(event:FlexEvent):void{
if(data!=null data.entityObject
[currentConcurrentCalls] != null){
strMaxConcurrentCalls =
data.entityObject.currentConcurrentCalls;
}
}
]]

mx:Text id=txtCurrentCalls text={strMaxConcurrentCalls}

Subject: [flexcoders] Help! Datagrid bug?
Hi,
I have a DataGrid with an inline itemRenderer.
Originally the DataGrid was using an Array as a data source.
Everything was fine.
Then I changed my datasource to an object containing sub-objects
and I
revised my datagrid accordingly.
I use DateChooser to fire off an event when a date is selected. The
DataGrid listens for the event and event-code adds the date to the
data source.
Everything works BUT...
When I enter dates in newest to older sequence, the DataGrid
renders
TWO rows for the older date. i.e:
Row 1: November 26, 2007
Row 1: November 26, 2007
Row 2: November 27, 2007
When I inspect the data source and the
DataGrid.dataProvider.source I
only see two entries.
When I hover over November 26, 2007, only the last instance
responds
by highlighting the row blue. I can't do anything to the first row.
The only way to make things right is to click on a header-column to
sort the grid or add another date. Then the duplicate magically
disappears.
I can't seem to do anything to the DataGrid (invalidateList, etc)
to
force update the grid.
Any ideas?
Thanks,

I'm trying to skin panels for use in Flex, but my corners, which are
rounded, keep getting squished. I'm sure I'm doing it right in Flash: My
own drawing is lined up with the reference point (0, 0), the 4
guidelines for scale9 are in the right places and everything. And in my
css file, I have:
Panel
{
borderSkin: Embed (source=flex_skins.swf,
symbol=Panel_borderSkin);
borderThicknessLeft: 16 ;
borderThicknessRight: 16 ;
borderThicknessTop: 0 ;
borderThicknessBottom: 16 ;
headerHeight: 16 ;
}
Where am I going wrong? Something else I should add, my panel gets
stretched depending on what size I want to make it at, but it looks like
the scale9 stuff is ignored completely, stretching the underlying swf as
if it were just one bitmap with no scale9 stuff.

Sometimes it would be really nice be able to access a list of currently attached listeners by doing something like myButton.listeners.

I can see this functionality being useful for various reasons. Ben, are you thinking you want to track down any listeners that are left over that are preventing garbage collection?

.NET does this and it comes in handy (although usually in situations that would not apply in Flex, such as threading and switching contexts).

Re: [flexcoders] Reference to the content area of a Panel component
I got this thing to work perfectly under Flex 3 but in Flex 2 which I am targeting for, it breaks. In Flex 3, the panel's border metrics give me top:30, left:10, right:10, and bottom:10.

[flexcoders] Re: ListCollectionView dispatches too many CollectionEvents after enableAutoUpdate
It's a web-services based search application. I'm basically lazy-
loading search results into a collection in chunks of 20 or so. The
chunks may be non-sequential, so I pad the ArrayCollection with empty
items that are replaced as they become available.
From what you're saying, disableAutoUpdate was actually intended to
work in the other direction - when updating the server with data
changes from the collection?
As a followup question, I've noticed that bindings in general tend to
fire more often than I'd expect. In some cases, 4 times for one
update. Can you offer some general ideas on what might cause
bindings to fire multiple times for a single update?

Thanks for the response, Alex. I understand that for most use
cases,
it would suffice to set a new source. However, I believe that
approach somewhat defeats the purpose of databinding. Suppose
you're
bind to an ArrayCollection with 1000 items and you need to change
20? Should you clone the ArrayCollection, change the 20 items, and
then rebind? Should you update the existing ArrayCollection and
have
the rest take care of itself? I prefer the latter - it's much
cleaner. However, I also don't want my bindings firing 20 times in
a
row.
Was there a particular use-case in mind when it was decided that
only
update events would be queued? It would help me better understand
enable/disableAutoUpdate to know.

Subject: [flexcoders] ListCollectionView dispatches too many
CollectionEvents after enableAutoUpdate
I am making some updates to an ArrayCollection. Since it's the
dataSource for a DataGrid, and I want the binding to update as
few
times as possible, I am using ArrayCollection.disableAutoUpdate
(),
making the changes, and then calling enableAutoUpdate() thinking
that
this will cause the binding to refresh only once for all the
changes. This would be the case if the ArrayCollection were
dispatching events of kind CollectionEventKind.UPDATE. Alas,
since
I
am replacing the items in the ArrayCollection and not merely
updating
them, it is CollectionEventKind.REPLACE. As you can see from
handlePendingUpdates() in ListCollectionView, it only gangs the
updates into a single refresh if the event.kind ==
CollectionEventKind.UPDATE. All other CollectionEvents are fired
sequentially, which would seem to defeat the purpose of
disableAutoUpdate. Could someone clue me in on why this should be
the case? I'm tempted to monkey-patch around it, and submit a
bug.
See the code below.
Thanks,
-tom
private function handlePendingUpdates():void
{
if (pendingUpdates)
{
var pu:Array = pendingUpdates;
pendingUpdates = null;

[flexcoders] Re: Am I the only one who wishes EventDispatcher exposed its listeners?
That wasn't specifically my thinking but that seems like it would be a super useful benefit of having that info available. I honestly can't remember every situation that has made me want this functionality but the most recent time was when I was trying to determine if a certain function had been registered as a listener yet. hasEventListener() is useless if you have potentially more than one listener. I was concerned that calling addEventListener() again would result in the handler firing multiple times, until I realized EventDispatcher has built-in protection against that.

RE: [flexcoders] Am I the only one who wishes EventDispatcher exposed its listeners?
Ben may not have been, but I always have been thinking of this. It would be handy in debugging memory issues for one thing, and also a bit quicker (and surer, given the possibility of missing one?) to loop and clear all than specifically clearing several events on, say, a streamLoader or similar. Or have a removeAllEventListeners() method ... I was wondering if there was any specific reason for it not being exposed, or whether in fact it was but I'd been a bit too dumb or lazy to spot it.

[flexcoders] How to remove the current sort on a Datagrid
Hi, I have a Datagrid that the user is able to edit directly. He is also allowed to add a new item in the grid. This is done by using addItem on the ArrayCollection that serves as the data provider for the grid. After that I use the editedField method of the datagrid to give focus to the first column of the newly created line so that the user is able to insert the information right away. I use as rowIndex the dataProviders length - 1. The problem is that when the grid is sorted by one of its three columns the dataProvider.lemgth - 1 no longer points to the inserted row. I successfully resorted the dataProvider using a new field with sequential number and replacing the sort on the ArrayCollection with a new one that uses this new field. So, the dataProvider.length - 1 points to the last row (just inserted). The new column is not displayed, it's just there for control. The problem now is that the DataGrid still displays the arrow on the column by which it was last sorted effectively deceiving the user into thinking that the sort has not changed. Does anyone know how to solve this? Thanks

[flexcoders] Load HTML from URL into Flex Component
I have a Flex 3 application that generates HTML, PDF, and Excel reports
from SQL Server Reporting Services.
In the case of HTML, I've been using navigateToURL() to load the result
into the browser. This works fine, but I'd really like to embed the
HTML into a Flex container and wrap the application
navigation/header/footer around it so that the user stays in the Flex
app and has access to all of the site navigation, etc.
In the Flex/AIR documentation there's lots of examples that use
HTMLControl / URLRequest to load the HTML content of a URL and then add
the HTMLControl display object. However, the required
flash.html.HTMLControl library is not available in Flex.
I tried using flash.display.Loader / URLRequest and then used
this.rawChildren.addChild() but that doesn't seem to work either - the
page is just blank. I thought maybe I needed to specify the
height/width but that didn't make any difference. Here's the code I'm
using:
import flash.display.Loader;
import flash.net.URLRequest;
private function load_html() : void {
var html:Loader = new Loader();
var urlReq:URLRequest = new URLRequest(http://www.symetri.com/;);
html.width = 900;
html.height = 900;
html.load(urlReq);
html_box.rawChildren.addChild(html);
}
The function runs on creationComplete() of the html_box VBox container.
Isn't there some type of HTMLLoader Flex component similar to SWFLoader
out there somewhere that will do this sort of thing? If not, any other
suggestions?

[flexcoders] a tree that keeps sorted
I'm trying to build a tree (Flex 2) that keeps its nodes sorted, even when
you edit them. I keep running into problems, though. Here's the basic app,
without the auto-sorting:
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml; layout=vertical
creationComplete=creationComplete()
mx:Script
![CDATA[
import mx.collections.SortField;
import mx.collections.Sort;
import mx.collections.ArrayCollection;
[Bindable] private var treedata:ArrayCollection =
new ArrayCollection([
{label:node0},
{label:node1},
{label:node2},
{label:node3},
{label:node4}
]);
private function creationComplete():void
{
var sort:Sort = new Sort;
sort.fields = [new SortField(label, true)];
treedata.sort = sort;
}
]]
/mx:Script
mx:Tree
id=tree
dataProvider={treedata}
width=200
editable=true
/
/mx:Application
Okay, so that lets you click on the nodes and edit them. What should be
done to get the nodes to re-sort after editing? I've tried:
itemEditEnd=treedata.refresh()
Doesn't work, because when itemEditEnd has been called, the dataprovider
hasn't actually been updated.
itemEditEnd=callLater(treedata.refresh, [])
Sorta works, until renamed node2 to node and then it just disappears.
If you rename the last node to something that would make it the first node,
you get an error.
private function reload():void
{
treedata.refresh();
tree.dataProvider = treedata;
}
itemEditEnd=callLater(reload)
This works ok, until you have a node with children like:
{label:node0, children:new ArrayCollection([{label:child-0-1},
{label:child-0-2}])},
And you expand it before renaming node4 to node. Then you get an error.
I've also tried this without using itemEditEnd and instead having the node
be a custom object that throws events. I run into the same issues. What's
the right way to do something that should be a pretty simple task?

You were correct that the button object was null. I rebuilt the component and started with just changing the style, rather than changing the style in the init function, which ran when on dataChange. It seems that when the dataChange event fires, the button does not yet exist. So when I try to change a style on one of the buttons, everything blows up.

Subject: [flexcoders] a tree that keeps sorted
I'm trying to build a tree (Flex 2) that keeps its nodes sorted, even
when you edit them. I keep running into problems, though. Here's the
basic app, without the auto-sorting:
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx= http://www.adobe.com/2006/mxml
http://www.adobe.com/2006/mxml layout=vertical
creationComplete=creationComplete()
mx:Script
![CDATA[
import mx.collections.SortField;
import mx.collections.Sort;
import mx.collections.ArrayCollection ;
[Bindable] private var treedata:ArrayCollection =
new ArrayCollection([
{label:node0},
{label:node1},
{label:node2},
{label:node3},
{label:node4}
]);
private function creationComplete():void
{
var sort:Sort = new Sort;
sort.fields = [new SortField(label, true)];
treedata.sort = sort;
}
]]
/mx:Script
mx:Tree
id=tree
dataProvider={treedata}
width=200
editable=true
/
/mx:Application
Okay, so that lets you click on the nodes and edit them. What should be
done to get the nodes to re-sort after editing? I've tried:
itemEditEnd=treedata.refresh()
Doesn't work, because when itemEditEnd has been called, the dataprovider
hasn't actually been updated.
itemEditEnd=callLater(treedata.refresh, [])
Sorta works, until renamed node2 to node and then it just
disappears. If you rename the last node to something that would make it
the first node, you get an error.
private function reload():void
{
treedata.refresh();
tree.dataProvider = treedata;
}
itemEditEnd=callLater(reload)
This works ok, until you have a node with children like:
{label:node0, children:new ArrayCollection([{label:child-0-1},
{label:child-0-2}])},
And you expand it before renaming node4 to node. Then you get an
error.
I've also tried this without using itemEditEnd and instead having the
node be a custom object that throws events. I run into the same issues.
What's the right way to do something that should be a pretty simple
task?

He is also allowed to add a new item in the grid. This is done by using addItem on the ArrayCollection that serves as the data provider for the grid. After that I use the editedField method of the datagrid to give focus to the first column of the newly created line so that the user is able to insert the information right away. I use as rowIndex the dataProviders length - 1. The problem is that when the grid is sorted by one of its three columns the dataProvider.lemgth - 1 no longer points to the inserted row. I successfully resorted the dataProvider using a new field with sequential number and replacing the sort on the ArrayCollection with a new one that uses this new field. So, the dataProvider.length - 1 points to the last row (just inserted). The new column is not displayed, it's just there for control. The problem now is that the DataGrid still displays the arrow on the column by which it was last sorted effectively deceiving the user into thinking that the sort has not changed. Does anyone know how to solve this? Thanks

It's a web-services based search application. I'm basically lazy-
loading search results into a collection in chunks of 20 or so. The
chunks may be non-sequential, so I pad the ArrayCollection with empty
items that are replaced as they become available.
From what you're saying, disableAutoUpdate was actually intended to
work in the other direction - when updating the server with data
changes from the collection?
As a followup question, I've noticed that bindings in general tend to
fire more often than I'd expect. In some cases, 4 times for one
update. Can you offer some general ideas on what might cause
bindings to fire multiple times for a single update?

Thanks for the response, Alex. I understand that for most use
cases,
it would suffice to set a new source. However, I believe that
approach somewhat defeats the purpose of databinding. Suppose
you're
bind to an ArrayCollection with 1000 items and you need to change
20? Should you clone the ArrayCollection, change the 20 items, and
then rebind? Should you update the existing ArrayCollection and
have
the rest take care of itself? I prefer the latter - it's much
cleaner. However, I also don't want my bindings firing 20 times in
a
row.
Was there a particular use-case in mind when it was decided that
only
update events would be queued? It would help me better understand
enable/disableAutoUpdate to know.

Subject: [flexcoders] ListCollectionView dispatches too many
CollectionEvents after enableAutoUpdate
I am making some updates to an ArrayCollection. Since it's the
dataSource for a DataGrid, and I want the binding to update as
few
times as possible, I am using ArrayCollection.disableAutoUpdate
(),
making the changes, and then calling enableAutoUpdate() thinking
that
this will cause the binding to refresh only once for all the
changes. This would be the case if the ArrayCollection were
dispatching events of kind CollectionEventKind.UPDATE. Alas,
since
I
am replacing the items in the ArrayCollection and not merely
updating
them, it is CollectionEventKind.REPLACE. As you can see from
handlePendingUpdates() in ListCollectionView, it only gangs the
updates into a single refresh if the event.kind ==
CollectionEventKind.UPDATE. All other CollectionEvents are fired
sequentially, which would seem to defeat the purpose of
disableAutoUpdate. Could someone clue me in on why this should be
the case? I'm tempted to monkey-patch around it, and submit a
bug.
See the code below.
Thanks,

Hi,
I know this problem, happened to me once.
This is a known issue that won't be fixed by Adobe.
It usually happens when you try to scroll - the data is presented in
a wrong way.
But it has a solution.
Add an event listener for FlexEvent.DataChange in your itemRenderer.
In the listener function do your code again.
for instance if i have an inline item renderer that presents a
property named currentConcurrentCalls, i need to add an event
listener for the dataChange event and render it again there :
mx:itemRenderer
mx:Component
mx:HBox width=100% creationComplete=doInit()
mx:Script
![CDATA[
import mx.events.FlexEvent;
import mx.resources.ResourceBundle;
[ResourceBundle(hostlynx)]
private static const _rb:ResourceBundle;
[Bindable]
private var strMaxConcurrentCalls:String;
private function doInit():void{
if(data!=null data.entityObject
[currentConcurrentCalls] != null){
strMaxConcurrentCalls =
data.entityObject.currentConcurrentCalls;
}
addEventListener(FlexEvent.DATA_CHANGE,dataChange);
}
private function dataChange(event:FlexEvent):void{
if(data!=null data.entityObject
[currentConcurrentCalls] != null){
strMaxConcurrentCalls =
data.entityObject.currentConcurrentCalls;
}
}
]]
/mx:Script
mx:Text id=txtCurrentCalls text={strMaxConcurrentCalls}
styleName=dataGridText/
/mx:HBox
/mx:Component
/mx:itemRenderer
Hope it helps,

Subject: [flexcoders] Help! Datagrid bug?
Hi,
I have a DataGrid with an inline itemRenderer.
Originally the DataGrid was using an Array as a data source.
Everything was fine.
Then I changed my datasource to an object containing sub-objects
and I
revised my datagrid accordingly.
I use DateChooser to fire off an event when a date is selected. The
DataGrid listens for the event and event-code adds the date to the
data source.
Everything works BUT...
When I enter dates in newest to older sequence, the DataGrid
renders
TWO rows for the older date. i.e:
Row 1: November 26, 2007
Row 1: November 26, 2007
Row 2: November 27, 2007
When I inspect the data source and the
DataGrid.dataProvider.source I
only see two entries.
When I hover over November 26, 2007, only the last instance
responds
by highlighting the row blue. I can't do anything to the first row.
The only way to make things right is to click on a header-column to
sort the grid or add another date. Then the duplicate magically
disappears.
I can't seem to do anything to the DataGrid (invalidateList, etc)
to
force update the grid.
Any ideas?
Thanks,
Danny
[flexcoders] How to do Dynamic DataGrid and Column Labels
Hi All, I have a database table A defined as ID Number Type Char(10) Attribute1 Char(20). . Attribute100 Char(20) to store the data. Another table B to store the labels of Attibute1 to Attribute100 depends on the Value of Type in table A. I have to create a datagrid to show the data depends on the different type values selected in a list. The grid should change the column labels and data depends on the Type selected. Table B (The type table) is dynamic, the user can add new types and column labels for Attribute1 to Attribute100. Any idea how this can be done in Flex 2. Thanks VN
[flexcoders] Re: Dynamically Setting width of a TextInput control
I think I have been speaking forked tongue a little. It is an itemRenderer but not for a DataGrid, it's for the springgraph. I was tracing through that code and it appears to create its item renderers as free standing controls on a canvas, hence my remark. In my case I want the nodes in the springgraph just to be text, hence the use of a TextInput control which gives me nice control over some of the styling. This means I also do not explicitly control the sequence in which the text of the control gets set. I override the set data() method so I can also change some other properties of the control at the same time. That's when I want to set the control width.

[flexcoders] Events and Non-Display Objects
General question here... I understand Event flow with objects in the display list. They flow either up (bubbling) or down (capture) between parent and child. Maybe an oversimplification but my question really is about how to handle events with objects that are not in the display list. How do you pass events from them? Like for instance, I've got this situation here... I have an MXML that is just an mx:Object. It's MXML because I'm defining some remoteObjects in it and that's just way more fun to do in MXML than in AS. So anyway, regardless, the methods inside are static and I don't want to draw the thing. It just needs to hang out and be available so I can make these remoting calls. So there's the rub. How can this MXML talk back to where it was called from? Can I use events for this or do I need to send a callback function? Any wisdom here would be awesome... this has been befuddling me for a while. -b

RE: [flexcoders] Am I the only one who wishes EventDispatcher exposed its listeners?
Does anyone from Adobe have info on why its not and/or if it might be someday? The Player's EventDispatcher class doesn't provide this capability, probably because it isn't part of the Document Object Model Level 3 Events Specification. (The Player obviously keeps a list of listeners, but this is done in C++ code and the list isn't exposed in ActionScript.) However, I suppose the framework could accomplish what you want by overriding addEventListener() and removeEventListener() in every subclass of EventDispatcher to keep track of the listeners.

[flexcoders] Embedded asset management strategy

I was planning on embedding each of these into the application and was thinking that a single class with static properties would be the best way to go.

So I'm basically asking for a sanity check or any suggestions, has anyone else had experience of doing this?

Okay, so that lets you click on the nodes and edit them. What should be
done to get the nodes to re-sort after editing? I've tried:
itemEditEnd=treedata.refresh()
Doesn't work, because when itemEditEnd has been called, the dataprovider
hasn't actually been updated.
itemEditEnd=callLater(treedata.refresh, [])
Sorta works, until renamed node2 to node and then it just disappears.
If you rename the last node to something that would make it the first node,
you get an error.
private function reload():void
{
treedata.refresh();
tree.dataProvider = treedata;
}
itemEditEnd=callLater(reload)
This works ok, until you have a node with children like:
{label:node0, children:new ArrayCollection([{label:child-0-1},
{label:child-0-2}])},
And you expand it before renaming node4 to node. Then you get an
error.
I've also tried this without using itemEditEnd and instead having the node
be a custom object that throws events. I run into the same issues. What's
the right way to do something that should be a pretty simple task?

[flexcoders] Re: Using multipleSelect with a Datagrid
Thanks for the Link Alex, I'm afraid my use case is rather more complicated than I explained. It is possible to select one of my rows regardless of my status, it is only when multiple rows are being selected that I want to exclude certain rows. In effect a single selection shows a canvas with a list of sub-options to be chosen, where as the multiple selection is geared to a single option. I think I will work around this, by doing a filter of the selected items in the grid before I process those rows. Andrew
Re: [flexcoders] Tracing HTTPService Data?
Thanks for the response. So there's no built-in debugging service available? Seems odd that we have no means to capture HTTP request responses inside of Flex.
[flexcoders] Re: Tracing HTTPService Data?
You can get at the contents of the messages using mx:TraceTarget on the client, which will spit a whole load of stuff to your console in debug mode. I don't use an http service, but I know that on the server you can alter the level of logging by adjusting the contents of the logging tag in services-config.xml. hth Simon --- In flexcoders@yahoogroups.com, flexnubslice [EMAIL PROTECTED] wrote: Hi there, Thanks in advance for your help. I'm a newcomer to Flex, but am definitely not new to Eclipse being a Java programmer by trade.

[flexcoders] How use hasOwnProperty() in combination with namespace
Hello This is my xml: foo xmlns=http://www.test.com/; atest/a c btest2/b /c /foo I created a namespace object: var ns : Namespace = xml.namespace(); To trace out the content from a I used for example: trace(xml.ns::a); This works fine.

Anyone has an idea? Thank you
RE: [flexcoders] Tracing HTTPService Data?
Please log an enhancement request for tooling to do this inside of Flex Builder. http://bugs.adobe.com/flex/ For now, I'd suggest using an HTTP sniffer.

[flexcoders] Differences between itemUpdated and setItemAt for ArrayCollections
Hi, I have a general question about when to use the two methods itemUpdated and setItemAt on ArrayCollections. if you use obj = getItemAt(someIndex) and then change some properties in the obj, what difference is there between using setItemAt(obj,someIndex) or using itemUpdated(obj)? Is there a particular reason to choose one over the other? Thanks, John
[flexcoders] itemEditEnd preventDefault
I have an item renderer/editor that does as-you-type validation using
standard Flex validators, and updates a valid property in the data. I wish
to prevent the edit from ending if the data is valid.
When tabbing, the following works in column one, but not in column two (the
last editable column):
private function handleItemEditEnd(event : DataGridEvent) : void {
if (event.itemRenderer.data.valid) {
// do some stuff
} else {
event.preventDefault();
}
Any ideas? Also, does the renderer get any access to this event? If I want
to move valid from the data to the renderer itself, I suppose I would have
to cast event.itemRenderer above to my renderer type, and call a method or
access a property.
Thanks.

Is there a particular reason to choose one over the other? Thanks, John you generally use setItemAt if you need to completly replace the object in that part of the arraycollection. For instance, we have a backend delegate class that instantiates new objects all the time, each being different but needs to replace the item that already exists in the collection (each object being replaced is progressivly more lightweight) so SetItemAt is necessary for us, its more costly because the view has to completly rerender for that item. getItemAt would be better if you are just changing a few attributes on the object, because a view only needs to change if certain attributes are different from before.

[flexcoders] Re: Shouldn't we use Flex to built website
Hi, I have read all this very interesting, but old post, about Flex templating. I currently work on Igenko, a Java/Flex CMS/ecommerce software based on PureMVC/GraniteDS/JBPM/Jackrabbits technos. The Backoffice will be in Flex, no problem for that. But I really don't know how to generate dynamically the Front Office that will be in FLex too. The content and the layout will be stored on the Java Content Repository, and should be used to dynamically generate the website. It is an easy thing to do Java/HTML world with template languages like Freemarker ou Velocity, but in Flex, I had no ideas untill I read this post. My question is : is there some new solution to make templates in Flex and let the user specify the layout at runtime ? Is there another solution than use and HTML layout with FLex components in it ?

Ideally I think we should send the model (XML) over the wire and have a template (SWF) do the layout. HTML works by sending model with embedded markup over the wire and rendering it all. My proposal is more in line with XML/XSL layout where you send a small model in XML and XSL styles it into a page on the client side.

Where this line is for me; Page layout. I find myself time and time again dreaming up new things for Flex and knowing I can't do them because as much as I want to abstract out how much a user 'knows' how to read, they are just so conditioned to seeing the format and style of html. This is where it will be interesting to see where Apollo fits into this situation. Allowing you to get the best of both worlds, Flex(web application) and HTML(web layout) to fuse together this hole in the space time continuum. Flex lacks text layout; this cannot be disputed. This is also why AJAX is so popular because it is fusing web text layout with web application. There is no line between web sites and web applications, it's how the user interface presents the intent of the web experience.

[flexcoders] Using Tweener for effect (such as showEffect)
I would like to use the Tweener class for my showEffect hideEffect,
however with Tweener whenever you add a tween it kicks off straight
away. I tried doing my tween inside a method and using that as the

this.setStyle( 'showEffect', this.testShowEffect );
private function testShowEffect ():void

trace( 'testShowEffect ' );
Tweener.addTween( this, { y: this.height, time: 1 } );
}
But that method doesn't get called when I change the visible to true.
Any ideas?
