[flexcoders] 2032 Stream Error - Deploying XML Application Configuration Data
I have created some application configuration files (e.g. app menu) that I need to load during startup. In development I have defined the following service that loads this data from a local file. mx:HTTPService id=appmenuService url=data/appmenu.xml resultFormat=e4x / I' m trying to deploy this app to a google site and am getting 2032 errors.

(All the files are in the same domain so I don't think crossdomain.xml is required here - I did add a cross domain file, but still get the error.) I'm not sure if this is a Path/Directory error or if I need to create a new application service on the server to retrieve that data. (This would seem to defeat the purpose of having XML configuration files in the first place). The more general question here is how to retrieve data from XML data that resides on the host? Any suggestions? TIA, Patrick

[flexcoders] Blogging Options/Services that support Flex apps? Wordpress/Other?
I'm interested in creating a Flex related blog that will also contain sample Flex code/apps. I'd prefer to manage this all in one place - without using a separate web host for the app data files. I don't need a database - just content management + swf storage. I'm looking at Wordpress but I'm not sure if they host the swf files. What are others using to do this - any suggestions - fwiw I do not currently have any hosting services so I'm pretty open. TIA Patrick

[flexcoders] Shared Data Options/Strategies
I am retrieving data from a service and saving this in a VO. This is done within a component (actually within a PopUp Search window) - I am saving the currently selected employee data record. However I want to make the VO data accessible across the entire app and to all components in the app (iow - this is application wide data). (BTW - This is static data that will not change - basically it is header info that appears on multiple forms etc.). (I know I can bind form elements to the VO for display purposes - just not sure how/where to create the VO). Some specific qns: If I define the VO at the application level, how do I pass this to a component (PopUp) so it can be populated and later made available to other app components? How do I reference the VO from other components? TIA, Patrick
[flexcoders] DataGrid ItemRenderer - Reuse with Parameters vs Cloning
I have a datagrid containing rows with multiple date columns. I need to change the cell background color based on the date value (e.g. 90 days old is red etc.) However the rules vary based on the column - for now I've created similar custom item renderers with different business rules based on the date value. (e.g. For Col 1 - use red if 90 days; for Col 2 use red if 15 days etc). This results in unnecessary duplication of code. Is there a way to pass a parameter to a Custom Item Renderer so I can reuse it with multiple columns. (BTW - I don't have access to the Advanced Data Grid so that is not an option). TIA, Patrick
[flexcoders] How to share VO with multiple components/views - Nested Binding?
I have some data (e.g. currently selected employee summary data) that appears (Read Only) on several views/components.

There must be a better way - anyone suggest an alternative appproach or provide an example of sharing a VO with multiple forms/views? TIA, Patrick

[flexcoders] Any future plans to support ODBC Connections for AIR applications?
I know this has come up before but there is a significant need to access data in desktop databases (Read Only would be OK). (e.g. I am working with the Google App Engine and there is no easy way to populate their datastore). A GUI upload app written in AIR could be great for this. I've thought about doing a small GUI in Python since the libraries are available - however I'd prefer to use AIR for GUI development. While support for this may not be available out of the box I wondered if some 3rd party libraries might be available for this - e.g. Python has extensive libraries than can be used to access Excel, Access etc. Any chance that similar Flex/AIR/Actionscript libs might be developed? Anyone else out there thought about doing this? TIA, Patrick
[flexcoders] Re: Any future plans to support ODBC Connections for AIR applications?
I understand the tcp approach but that's just a really roundabout/indirect approach vs a direct db connection of some sort (maybe native drivers if ODBC is not your thing - again look at the Python libraries) . I'd be curious to hear the official Adobe position on this and whether this is a feature they may offer in the future. Since AIR allows access to the file system (XML or csv text files only AFAIK) I can see folks asking for other access to other file types (e.g. MS Excel). I can also understand that Adobe may see this somewhat problematic from a marketing/product positioning/support standpoint. FWIW I don't think this issue will go away if AIR gets real traction in the market place. There are just so many desktop database apps out there that are begging to be web enabled. Just my $0.02c- Patrick --- In flexcoders@yahoogroups.com, Josh McDonald [EMAIL PROTECTED] wrote: That being said, I know you can do ODBC over tcp, so if you've got some sort of server available that can route from odbc over tcp to a local file DSN, you could probably write a socket ODBC client for AIR, and then charge people in your position a fortune to use it. People stuck in Windows-world seem to be used to that sort of thing. Sounds like pain though :D -Josh On Thu, Jul 31, 2008 at 5:45 PM, Josh McDonald [EMAIL PROTECTED] wrote: It's pretty evil.

[flexcoders] How to control positioning of Dynamic Control in a panel?
I have a panel that will contain a dynamically created custom grid component(the size is determined at run time). The grid is added to the panel via the panel.AddChild() method and is placed at the bottom of the form by default. I need to place a control bar (and other controls) below the grid. Currently the AddChild() puts the grid at the bottom of the form, after, rather than before the control bar. I need it to go before the control bar (in the middle of a VBox actually). Is there a way to set up a placeholder or template to force the grid placement correctly? Is this possible? Any refs on how to do this? TIA, Patrick

[flexcoders] Re: Problem Adding Custom Event Listeners in a component?
Thx - I think I get it now - the default dispatcher works only for
parents /child relationships of graphics objects only. If objects are
external (e.g. siblings, non visual etc.) a custom dispatcher than
maintains a list of related components via some registration mechanism
is required. I assume the best place to perform such registration would
be in the constructor of my custom class. (I assume this is how
Cairngorm and other frameworks are managing inter object/component
communication).
Thx for setting me straight here. FWIW this is part of a game board demo
I'm putting together and it could be the basis for a useful
demo/tutorial on to share with others - any suggestions on where to post
this type of example (I don't currently maintain a web site or blog).?

In general, you have to be listening to the object that is

If you use bubble or capture, you can listen to parents if they are

3 siblings would need to know about each other and listen to each

Having them register with a central object that dispatches on their
behalf or they dispatch from might be better. That's how
RadioButton/RadioButtonGroup work.

This looks like it should work, but only the MouseOver event is ever
fired - am I missing something obvious?

[flexcoders] Passing Initialization Parameter to a Popup Form ?
Is there a way to pass/initialize a parameter when it is initially created - based on the value passed I plan to render the popup differently as part of my create complete processing in the popup. I don't want to set/pass the variables after I've created the popup since that is too late. Any ideas, TIA, Patrick
[flexcoders] BSOD Crashes (in Windows) while debugging in Flex - Is this a known problem?
I'm Running XP (SP3) and have had several BSOD crashes while starting a debug session(Driver IRQL_Not_Less_OR_EQual error). On restart I get a windows message that system has recovered from serious error. (I may have had a run time Null Object Ref error in my code - not sure if that would be a factor) FWIW - my system is otherwise very stable. Anyone else experienced this? Patrick
[flexcoders] Re: Enumerating throug container/control arrays in Flex/Actionscript?
Hopefully I won't need to - however old habits die hard -maybe a FAQ/guide for some of us older client/server developers would be useful - Flex is a different way of thinking/different mindset. I think you just turned on a light bulb for me - using loosely coupled events can accomplish the same thing w/out needing to locate specific controls etc. (Imagine a scenario in a data entry app were a checkbox click requires the enabling/disabling of a group of related controls - registering and handling events is the Flex way - different than what I'm used to). BTW - Managing a separate list in the manner you described seems redundant (unless there is performance penalty) - I'd expect the Flex framework to make that data readily available. Recursion is a bit counter intuitive. Again, I'm new to Flex and with a better understanding of the framework I may well see problems/solutions etc in a different light. Thx for your response - so much to learn!

[flexcoders] Pass a Run Time Composite Component to customize a Pop Up Form?
I't trying to create a composite control (in AS) at run time and pass this to a popup (as an object) - the popup is responsible for the display and the contents vary based on a user input (e.g. 2*2 grid; 3*3 grid etc). My initial thought was to create a composite component and then pass this for display via the Popup Manager as part of the popup. However I'm not sure this will work as it appears that the composite control methods (createChildren etc) apply to the current form and do not support the creation of a package that can be rendered in a separate form/window. Maybe I need to have the popup form create the composite control directly instead? Any suggestions/comments? TIA, Patrick

[flexcoders] Re: Create border for inner subgrids within a grid - How?
Alex,
Thanks - I think that approach will require me to build multiple
subgrids and treat each of these subgrid as a separate griditem - thus
creating additional nesting, rather than 1 large grid. I was hoping for
to avoid that - is there any other way to accomplish this (I suspect
not).
Thx again,
Patrick

[flexcoders] Custom (mxml) UI Components in Flex?
Hi Just getting into flex in my spare time and trying to learn as quickly as possible - so excuse me if some of my postings/questions seem somewhat redundant - however these groups are a valuable resource for future Flex noobies so hopefully others will benefit from the QA. (Later on I may compile a list of (HowDoI qns )that I've had to deal with in learning Flex and post ??where??). I know I can create custom classes defined in .as files and reuse these. Is is possible to create a custom component (say a composite if several multiple UI components (e.g. a logon form definition) in an .mxml file ant then reuse these? The examples in the docs all use .as files so I'm wondering if it's possible to do the same thing with mxml files. TIA, Patrick

[flexcoders] How to create a n * n grid dynamically (not datagrid)
Hi, I'm new to this group and just started learning Flex 3. I want to try creating/adding a grid with a variable (user specified) # of cells. SO the grid size is defined at run time. Scenario is : User selects grid size (2x2; 3x3 etc) from combo box and corresponding grid is displayed - also want to add a button to each cell. Would appreciate any pointers on how to do this in Flex 3? TIA, Patrick
