[flexcoders] ComboBox and Switching State
I posted this last week and never got a response, so here it is again.
If I can get anyone to agree with my hypothesis, I'll post it as a bug
in the Flex Bug Database.
In a nutshell, the issue is this ... In Flex 2 if you initialized or
set a ComboBox in state ONE, then switched to state TWO (without the
ComboBox), when returning to state ONE the ComboBox would have the
same data values.
In Flex 3, it seems that the ComboBox gets reset either when entering
state TWO or returning to state ONE.
Here is a small test app that verifies this (or at least I think it does).
Click the Initialize button first to set up the ComboBox, then click
the Switch button to switch to state TWO and show the ComboBox. You'll
see it no longer has it's value. While viewing the ComboBox, choose a
different value and the switch back to state ONE then back to state
TWO. The value gets lost.
Here's the test app:
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
layout=absolute
mx:states
mx:State name=show
mx:AddChild position=after relativeTo={b_show}

cb_freight.selectedIndex = -1;
cb_freight.text=This is a test;
currentState='';
}

[flexcoders] Flex 3 ComboBox and Editable property
Hi, I'm attempting to migrate from Flex2 to 3. One issue I'm have is with the ComboBox. In particular, with the Editable property set true. Previously, if I wanted to set an editable combobox to display a value OTHER than one of the values in the dataProvider (an ArrayCollection of Strings), I just set the 'text' property to some string. In Flex3, this does not seem to have any effect. I even added setting the selectedIndex to -1, first but still no change. The desired text value does not show up, just the 1st element of the dataProvider. cb_freight.selectedIndex = -1; cb_freight.text = This is a test; Anyone else found this the case?
[flexcoders] MessageBrokerServlet unavailable
I have upgraded to LCDS 2.5 and FlexBuilder 2.0.1 Hotfix 2 (this was
from FDS and Hotfix 1). I am having some real difficulty getting the
MessageBroker to respond. I have checked the logs to see the the
MessageBroker seems to startup without any issues. However, when I try
to access it via (webapp)/messagebroker/amf I get an error the the
MessageBrokerServlet is unavailable.
I have gone through all the configuration files to simplify as much as
possible and checked them with the config files that come with LCDS
for variances. They all seem to be in sync.
There are no messages in the logs (I have DEBUG turned on) when I try
to access the messagebroker. I find that surprising. Should there be
even if it fails??
Anyway, I all out of ideas on how to get this working. I would
appreciate any suggestions from those of you who might have had any
similar experiences. I am posting part of the startup log below.

[flexcoders] Datagrid tabbing with itemEditor
The scenario is there is a custom editor in say, column 2 of 4 in a DG and I need to a itemEndEdit event handler to extract data. In the handler I use the preventDefault() to take the default editor out of the picture and use destroyItemEditor() to remove the custom editor. This works OK. The problem I am having is that it also stops the normal tabbing to the next column. Do I have to implement my own tabbing scheme too or is there some other way to allow the DG to continue to handle tabbing? This is a thorny issue for me as I have many DGs that are in this situation. If anyone has solved the problem, I'd sure appreciate some advice. Thanks.

[flexcoders] Re: Keyboarding up/down editable columns in Datagrid
That had some interesting results. In the KeyDown event handler I set
editedItemPosition as per your suggestion and I commented out all of the
code in my endEdit handler (but did not removed the handler from the
datagrid). To my delight, I could arrow down the column with no issues.
Then I uncommented my endEdit code and the new cell would never gain
focus (or gained it and lost it immediately, not sure which).
A second test was to re-comment all the endEdit code except for the
event.preventDefault at the beginning and
DataGrid(event.currentTarget).destroyItemEditor at the end. The same
results. That is, the new cell would not gain focus.
This brought the realization that I was using the preventDefault method
incorrectly. It is this call that disallows focus to move to the new
cell. Once I commented it out and restored all the other code of the
endEdit handler, it worked like a charm.
Thanks for taking the time to suggest another way to look at things. I
appreciate it a lot.

If on some keystroke you simply set editedItemPosition, the code says
that it will dispatch ITEM_EDIT_END before trying to set the editor to
the new place.

I have one more slight problem along this line maybe you could

Unfortunately, although I move the focus to the column in the new

the endEdit code gets call after this focus occurs and
consequently
focus is lost. I have tried 'callLater' for the focus method but
have
the same result. Even, setup a timer to delay the focus for 200
ms.
Still endedit come along and focus is lost. Have you or any other

Setting the focus caused the endevent for the previous cell which then
causes the current cell to lose focus. Again, I am probably making
things too complex.

[flexcoders] Keyboarding up/down editable columns in Datagrid
Has anyone come up with a good way to let a user move up/down in an editable column of a datagrid using the keyboard? These columns use a TextInput as the itemEditor. Right now I use a handler for the keyFocusChangeEvent on the datagrid to handle TAB and Shift-TAB keys to move horizontally through the rows. However, moving up/down in the columns is more difficult because the editor's TextInput captures the Return key and the TextFieldAutomationHelper class captures all the other interesting keystrokes (navigation keys like UP and DOWN arrows) and it seems the DataGrid is only interested in the TAB key when it handles focusChange events. I'm not sure how a focusEvent.KEY_FOCUS_CHANGE is dispatched as this seems to occur somewhere in the flash code which is unaccessible. I am probably making this more complex than it needs to be. Any ideas?

Use the down arrow key to move from foo to bar.
Thanks a lot for the reply. That is a nice, simple solution.
I have one more slight problem along this line maybe you could shed
some light on. In my app, I use the endEdit function for the datagrid.
Unfortunately, although I move the focus to the column in the new row,
the endEdit code gets call after this focus occurs and consequently
focus is lost. I have tried 'callLater' for the focus method but have
the same result. Even, setup a timer to delay the focus for 200 ms.
Still endedit come along and focus is lost. Have you or any other
reader run into this issue?

Right now I use a handler for the keyFocusChangeEvent on the

to handle TAB and Shift-TAB keys to move horizontally through the

because
the editor's TextInput captures the Return key and the

Another note - actually, the setting of the focus is what is causing
the endedit event for the previous cell. Seems like a catch-22.
Setting the focus caused the endevent for the previous cell which then
causes the current cell to lose focus. Again, I am probably making
things too complex.

When I add a custom itemrenderer to a cell of my datagrid, the tabbing
order of my screen is broken, i.e., the cell with the itemrenderer is

What you need to do in this situation is handle your own tabbing
through the DataGrid. This can be accomplished by adding a
'keyFocusChange' handler to the grid.
The handler will have to listen for tab character. If it finds there
was one, then depending on the current row and column, it moves the
focus to the next cell desired. In this way you can skip cells you do
not want to have focused.
Here is a sample piece of code I used to manage tabbing in a grid that
has a renderer and editor in it.
// handler for request to move focus to next column when using tab key
in the DataGrid
private function handleKeyFocusChange(event:FocusEvent):void{
// make sure it is a focus change envent and the tab character
if(event.type == FocusEvent.KEY_FOCUS_CHANGE event.keyCode == 9){
var eip:Object; // used to set the focus at a row and column
if((DataGrid(event.currentTarget)).editedItemPosition != null){
var colPosition : int =
(DataGrid(event.currentTarget)).editedItemPosition.columnIndex;
var rowPosition : int =
(DataGrid(event.currentTarget)).editedItemPosition.rowIndex;
if(rowPosition = 0){
// going backwards off the datagrid
if(rowPosition == 0 colPosition ==0 event.shiftKey == true)
cb_manufacturer.setFocus(); // somewhere on the page
// going forward off the datagrid
else if(rowPosition == (receiptItems.length -1) colPosition ==
2 event.shiftKey == false)
ti_heat_number.setFocus(); // somewhere else on the page //
going forward/backward in grid
else{
switch(colPosition){
case COLUMN_QUANTITY: // QUANTITY
colPosition = event.shiftKey ? COLUMN_LOCATION : COLUMN_LENGTH;
rowPosition = event.shiftKey ? rowPosition - 1 : rowPosition;
break;
case COLUMN_LENGTH: // LENGTH
colPosition = event.shiftKey ? COLUMN_QUANTITY : COLUMN_LOCATION;
break;
case COLUMN_LOCATION: // PACKAGE
colPosition = event.shiftKey ? COLUMN_LENGTH : COLUMN_QUANTITY;
rowPosition = event.shiftKey ? rowPosition : rowPosition + 1;
break;
} // end switch
eip = {columnIndex:colPosition, rowIndex:rowPosition};
// focusColumn method sets the focus on the proper column
callLater(focusColumn,[eip]);
} // end else
} // end if

[flexcoders] 2nd datagrid - no headers, wrong size
I've been spending a lot of time trying to overcome this issue without any success. Hopefully someone out there has a suggestion. I have datagrid within a vbox in a component. The grid takes up as much space as is available (height='100%'). There is another state which does the following: 1) reduces the height of the 1st datagrid to a fixed value (344) 2) adds a 2nd datagrid (height='124') into the vbox as the lastchild. The problem is when the state gets switched and the 2nd datagrid gets added.. 1) the headers are missing 2) the requested size is not honored When looking at the state in design mode, the headers are present and the size of the 2nd grid is correct. Has anyone run into issues similar to this? Any resolutions? The code is rather long, but I will post it if anyone is interested. Thanks

Thanks Well, to answer my own question (and for the sake of anyone else who see symptoms like this) - the problem was the use of a transition. When the new state was displayed a Resize transition moved from a height of 0 to a more normal size height (170). For some reason, the headers of the datagrid got lost in that transition. Once I removed the transition, it behaved as expected. I suppose there is a way to still use the resize transition without losing the headers however that's for another day.
[flexcoders] AMF serialization of floats (REPOST)
My original post seems to have gotten removed, so I am posting again with hopes someone has experience with this issue. I am transfering float values from Java DTOs to corresponding AS objects using both FDS and remote objects. The Java float values have a precision of 4 decimal places (verified before serialization e.g. 0.4398) yet when they are created in AS they have 16 decimal places with values extending throughout the 16 digits (e.g. 0.4398283772047382). I suppose I can round the values when I receive them at the client, but can someone tell me if there's a better way to insure the destination values are the same as the source? Thanks, Mike Yahoo!

Dave, thanks for your response. I'm not sure what exact number type you have in mind (Integer?BigDecimal?). The data is decimal data, no getting around that. There don't seem to many choices as far as what data type to use. What do flex programmers do in this situation when they want to serialize currency values, such as item prices which have 2 decimal precision? Convert to a String first? It seems to me that it boils down to one thing - the data will have to be manipulated in *some* way once it has been reconstituted on the client side. This manipulation might be converting the String back to a Number, rounding the Number to the desired precision, or any of several other methods.

[flexcoders] Editing datagrid w/nested properties
Can someone tell me if this is possible or should I give up and remove the nested properties from the datasource. I have a datagrid bound to an arraycollection. The collection is a list of Order Items. Each Order Item has a Product which in turns has several properties to display. I have used a LabelFunction to display the Product properties. No problem. However, I would like the user to be able to edit those properties. Right now the DataGrid itemEditorItemEditEndHandler throws an exception because it cannot access the nested property since it uses the data[property] ... where data=OrderItem and property=product.description. I thought writing my own endEdit event handler might be the way to go to be able to modify the property myself, however it seems the DataGrid's itemEditorItemEditEndHandler is still going to get called with the same results.

[flexcoders] Re: So? What are folks here actually building...?
An ambitious project to convert a client/server order entry/inventory management/purchasing system for a stainless steel distributor with offices in several countries. This may not be the best project to use as an introduction to Flex but it is certainly not boring. I am coming from a j2ee background with a fair amount of experience in developing web application using that architecture. However, for the client side of things I do find Flex pretty daunting. The most frustrating part is that I have a fairly complex data structure and am struggling with trying to integrate that into the flex UI. In particular, the objects I need to display have deep graphs and I am finding it difficult to display (but mostly manipulate) the data in a DataGrid. I'm sure this will all become clearer as I get a greater knowledge of Flex but right now it is frustrating.

In the examples I have seen you retrieve a service from the ServiceLocator with something like this: ServiceLocator.getInstance().getService(ordersService); However, the getService() method returns an AbstractService which only WebService and RemoteObject extend. Is there some other mechanism to be able to use a DataService within the ServiceLocator? The getInvokerService method also does not look like it is useful for this purpose. Thanks, Mike Yahoo!

When calling a POJO method what is the preferred way to signal the RemotingService that an error condition has occurred?

The high level message should be sufficient for my purposes. -Mike --- In flexcoders@yahoogroups.com, Peter Farland [EMAIL PROTECTED] wrote: I think throwing an exception is ok - in Flex 2 this should be handled better where by we now use bean-rules to serialize Throwable instances (including read only properties) and return root cause chains too. The client will always receive an mx.rpc.events.FaultEvent which always has an mx.rpc.Fault instance that will contain the high level message information from your exception, but the rootCause will be the serialized bean info of your throwable type (and technically you could even create ActionScript types mapped to the Java throwable types using [RemoteClass(alias=xyz)]).

[flexcoders] Re: Flex dataservices and Spring
Well Pete, I finally got it to work.
It seems like the problem was in using the Spring framework. Something
about setting either the context-param or listener for Spring in my
web.xml file was causing the conflict. Once I removed these references
and simply instantiated the bean in my Assembler class instead of
having Spring inject it, all worked as expected.
I have read http://www.devx.com/Adobe/Article/31489 about the changes
to beta3 and one of the points was Flex Data Services has better
support for Spring. However, as of yet I cannot find any references in
the documentation about the usage of Spring with FDS.
Has anyone else used Spring with FDS or has a reference on how that
might be done?
Thanks,
Mike

Hmm, it looks like the endpoints are starting up fine, but there's
something wrong with the destination configuration as the error message

changing the configuration?
If you can't solve it, would it be possible to send a .war of the app to
me off line?

Pete, thanks for the response. Yes, you're probably right. It appears
that the endpoints are not being created. My guess is it has something
to do with a security setting ( I removed all references to security
in the config files, as they did not seem necessary). That's just a
wild guess. Here's some of the log from the stdout.log file.

Mike,
The fact that the error said the send failed means that perhaps the
RTMP
channel isn't running... so I'm guessing something went wrong on
starting the web application. Most likely the configuration was
invalid.
Can you look at the server startup output (perhaps in the console
window
itself or in the web application logs... depending on how you launched
Tomcat) for an indication as to whether there were such errors, and,
hopefully, a clue as to what is wrong with the config?

[flexcoders] Re: Flex dataservices:
Pete, thanks for the response. Yes, you're probably right. It appears
that the endpoints are not being created. My guess is it has something
to do with a security setting ( I removed all references to security
in the config files, as they did not seem necessary). That's just a
wild guess. Here's some of the log from the stdout.log file.

Subject: [flexcoders] Flex dataservices:
I have read some of the posts on issues similar to this one.
Especially the Hank Williams and Peter Farland exchange. However, this
problem is different enough that their posts did not help.
I am trying to adapt the samples examples to work with an app I am
developing. (BTW, all the samples work on my Tomcat test server
running on Windows.)
The issues I have is a failure when I try to a fill on a DataService.
I've attempted to simplify the configuration files but I must have
left something out. Anyone who has some experience in this area may
easily spot my mistake but I have tried all the changes I can think of
without any change in the result.
Here are the gory details:
// This is the script that creates the data service and tries to
populate the orders arraycollection.
mx:Script
![CDATA[
import mx.data.DataService;
import mx.collections.ArrayCollection;
import com.othenos.metalsmith.order.OrderRow;
public var ds:DataService;
[Bindable]
public var orders:ArrayCollection;
[Bindable]
public var orderRow:OrderRow;
public function initApp():void{
orders = new ArrayCollection();
ds = new DataService(orderRow);
ds.fill(orders);
}
]]
/mx:Script
// Here is the AS class that acts as the DTO
// **
