[flexcoders] Modules Example and Tutorial
Peter Ent has posted an excellent example of how to use modules, including how to communicate with modules and handle module events. See: http://weblogs.macromedia.com/pent/archives/2007/01/building_module.cfm His example and explanations answer many of the questions I've seen lately about Modules. He includes a complete code download.
[flexcoders] Re: Compiling modules
Great question. I've run into the same problem. How do you use Flex Builder to compile just the module? The only work-around I've found so far is to right-click on the module name in the navigator panel and select Run As Flex Application. This command will create a .swf and .html files for the module and try to load it in the browser (where nothing will display). It's not the best solution and I hope someone posts a better one, but it is all I've found to work so far. I did search through the Flex 2.0.1 help files but did not find anything. Bruce
[flexcoders] Unable To Install Flex 2 Update
NO JOY in installing the Flex 2.01 update. I TRIED installing the Flex 2.01 update. My configuration is Windows XP SP2 and I was running Flex Builder 2.0 (Educational Version). I downloaded the Windows update from here: http://www.adobe.com/support/documentation/en/flex/2/install.html (144 MB download). After the download completed, I ran the downloaded file (named flexbuilder2_201updater.exe) and went through the process of installing FlexBuilder 2.01. The installer needed to restart my computer before completing the process. After my computer restarted, I expected to see the installer tell me it was finished. But I never got any more messages from the installer. So, after waiting a few minutes, I ran Flex Builder. Still said 2.0 on the splash screen. I went to Help - Product Details and then clicked on Feature Details and saw that my Flex Builder 2 Core is 2.0.143459 and so is my Flex Builder 2 Standalone. However, when I try to open one of my Flex projects I get an error message!!! The MXML editor is not available!!! So I closed Flex Builder and ran the download again. Only now I get the message that an existing Flex Builder installation was not found and the installer will not run!!! I'm now going to try reinstalling the original software!!! I knew I should NOT have tried to do this on a Friday afternoon. Anyone else have a problem or success in installing the update?
[flexcoders] Re: Flex 2 Updater Available for Download
Paul: Did you upgrade Flex to 2.01? If so what is your OS (Windows)? I could not get the update to install correctly and had to reinstall Flex Builder from the original CD. Bruce --- In flexcoders@yahoogroups.com, Paul Whitelock [EMAIL PROTECTED] wrote: It can be found here: http://www.adobe.com/support/flex/downloads_updaters.html It's not clear to me whether the updater updates Flex Charting and Flex Data Services. The page says: The 2.0.1 updates for these Flex products can be implemented by installing the full, updated versions of the products. So I don't know whether you have to install the product from scratch if you are using Flex Charting and Flex Data Services.
[flexcoders] Re: Closing An Open Item In Flex Tree Control
Thanks for the reply. Unfortunately, your suggestion did not work. I think it did not work because I am not using a root node. To see an example of what I'm doing please go here: http://www.brucephillips.name/blog/index.cfm/2007/1/1/How-To-Use-An-ArrayCollection-As-The-Data-Provider--For-The-Flex-2-Tree-Control and click on the demonstration application.

[flexcoders] Closing An Open Item In Flex Tree Control
Anyone have a working example they can point me to that demonstrates how to close an open item in a Flex Tree control? After studying the Tree control in the Flex 2 Language Reference, it seems to indicate that method expandItem will also close an open item if the second argument is set to false. However, I've not gotten that to work. I can open items using method expandItem just fine. Of course, the Flex 2 Developer's Guide only has very limited information on using the Tree control's methods and I've not found anything when doing an Internet search. Bruce
[flexcoders] Re: remoting with public access modifier in cfc
Kevin Schmidt posted this in response to a blog entry on Ray Camden's blog: you only need to set access=remote if you are using flex with web services. If you are usimg AMF (Flash Remoting) you don't need to set access=remote. See: http://ray.camdenfamily.com/index.cfm/2006/11/24/Next-build-of-my-Flex-2ColdFusion-Security-Homework#more and check the comments It makes sense since both the Flex app and the CFC are on the same host, just like the CFM file and the CFC are on the same host.
[flexcoders] Re: Using ActionScript 3.0 WebService Class - Need Help
Carson - thanks for the reply. I had previously tried handling the
load event and then calling the getRate method from within the load

loadWSDL being handled separately.
Any other ideas?

The loadWSDL() method fires asycnhronously. You will need to load the

I'm trying to learn how to use the WebService class in ActionScript

I'm having great difficulty getting the code below to work. I've read

The below code uses the currency exchange rate WebService described

WebService works as I've tested it using ColdFusion.
Any help you can provide me would be much appreciated and I will

[flexcoders] Re: Using ActionScript 3.0 WebService Class - Need Help
I think part of my problem with this web service might be related to
the XML name space (see page 1150 in the Flex 2.0 Developer's Guide).
However, I cannot figure out what the name space should be for the
web service.
I was able to use a different web service for my tutorial on using web
services that return XML in Flex 2.0. You can read the tutorial here:
http://www.brucephillips.name/blog/index.cfm/2006/10/22/Using-XML-in-Flex--Tutorial-Part-4--WebService
I certainly appreciate any feed back or suggestions on how to get the
WebService code below to work.

[flexcoders] Re: Process CheckBoxes Displayed Inside a DataGrid
Tracy: Thanks for the response. I was afraid that was the case. I did notice that the checks don't remain if you scroll. I'll have to come up with a better way to do this. I wanted the user to be able to check 30 items in a list of 100 and after checking the last item and clicking on a submit button the database would be updated. I did not want to have to call the CFC to update the database after each check. Bruce --- In flexcoders@yahoogroups.com, Tracy Spratt [EMAIL PROTECTED] wrote: When working with data-driven controls, you will almost always work with the dataprovider and not with the rendered display elements. This is in part because the list based controls recycle the display elements when you scroll. So you can't loop through the rows of a dataGrid and read the value of the check box. In fact if you have implemented this already, you may have noticed that the check boxes do not always hold their values when you scroll. Instead, what you want to do is have your checkbox renderer undate a property on the dataProvider item when the user changes the checked state Then, when you are ready, you loop over the items in the dataProvider and read the value of the updated property.
