How do I load XML from a local file into a List component in MXML Flash Builder 4?
I tried using Actionscript to create a loader, but I can't seem to add an event listener to the loader. I've tried to create a local service but I couldn't get that to work either.
I'm making an XML driven AIR app. I plan on having multiple XML files being used - some for content and some for storing settings, state etc.
I've been trying to create a custom mxml component that extends another custom mxml component (i.e.MyMXMLComponent -> BaseMXMLComponent -> Group). I've been reading that trying to add visual children to MyMXMLComponent caused error with Flex 3 but that's no longer the case with Flex 4.
What I want to know is whether this is a supported/fixed/documented feature of Flex 4? or just some undefined behavior in Flex 4 that may get changed with future updates?
if this is supported and documented feature, does anyone have link pointing to adobe document stating it as such?
I have a combobox and list component on the stage. The combobox has 3 selections. How do I get it so that each selection triggers the specific xml file to load into the list component? I can't get them to communicate to each other.
View 1 RepliesI have two Lists (components) on stage. The first one (mainList populates from an XML called topics.xml
[Code]...
on event handler change, I want to load the second list on the other list component, called subList..It's not loading.. I believe it's because when it reads the data from my topics list, it reads topic1.xml instead of "topic1.xml" ( reads without the quotes). If I unquote line v.list.load("subtopic.xml"), it works, but I need it to be loaded from the XML..

I am trying to create my first real world Flex application. I will have a lot of different data entry / data view screens so I thought I would create many different components to deal with each different type of data that was being returned. I have a MXML application called Layout, and have component called "Navigator" which controls the menu, as well as a ViewStack called "MainContent".
I want the Navigator component to change the ViewStack on the Layout application to that of another Component (each Component is embedded within the Canvas of each ViewStack). I have a click handler on my Navigator which looks like this: Layout.ContentFrame.selectedChild=event.itemRenderer.data.clickValue; However it shows the error "Access of possibly undefined property ContentFrame through a reference with a static type Class." Is my approach a good way of doing it? I have attempted referencing it using FlexGlobals.Layout and topLevelApplication.Layout... neither of which work?[URL]
I've got years of experience with AS3 but am very new to MXML. I've downloaded Flash Builder 4.5 in the hope of building some mobile applications and am stumbling over the integration of Actionscript with MXML. I need to dynamically build an elaborate game interface by drawing shapes. For some reason, Flash Builder tells me I have an error in the Actionscript here:

I'm looking to create a flashBuilder document which uses seperate MXML files as "views" which are controlled by states - I believe it's a design pattern of sorts but I'm relatively new to FlashBuilder. I was wondering if anyone knew what design pattern it was and if I can be pointed in the direction of some good references! FYI I'm looking into using FlashBuilder to design Android apps

eg. of mxml componet may be as simple as button label or text as complex as repeater whose data provider is a web service ( means a fresh quesy should be made to pull the data and refresh the dataprovider of repeater )
I'm trying to do this using only mxml, no <script> tags, although I don't necessarily need a solution that's only mxml. It was more of an educational exercise to see if I could do it all in mxml. I have a custom component that has a slider and textinput and their value/text properties are bound together. I'm surfacing a few properties of the slider in my component so that it can sort of be treated like a slider.

View 1 RepliesI imported an .fxp project into a Flash Builder and then observed there are 5 .mxml files in the src/(default package) directory. Silly question -- how to run each of these five files?
Since I've named the project differently than any of the .mxml files, whenever I try to run something it uses the default (empty) .mxml file named after the project. Deleting that empty mxml file didn't help anything. I also tried to clean the project, but nothing changes (although I see the directories refresh with the same contents). There are no html files in the bin-debug directory.
There must be some simple way to run those .mxml files that I'm missing.
I have 3 mxml components. In Component 1, I let the users fill in some data. In Component 3 I want to use the data, but I can't find a way to make it work.

I have two components. One is called "InsideComp" and one is called "OutsideComp". OutsideComp has InsideComp as one piece of its component, and in my main MXML file, I have embedded an instance of OutsideComp. How do I access a public variable of InsideComp within my main MXML file?In Actionscript, I could just do something like:OutsideComp.InsideComp.valToChange = 5; But I dont know how to do it in MXML. I know this is probably an easy question.

How to open an mxml file? Been using Actionscript for a while, but new to Flex.
I've a project that i've been asked to make a quick change to with 3 folders and a mxml file, but have no idea how to open and edit them with Flex!
I just upgraded out Flex project to use SDK version 4.5.1.21328 and the Flash Builder to version 4.5
All of the sudden, I'm getting several red tags on the Flash Builder: "could not resolve s:State/fx:Script/whatever to a component implementation"
However, the project builds fine with Maven, and seems to work well too.
Does anyone have any information on how to remove these "problems"?

I am assuming the compiler isn't lying to me so how do I get those objects (children) to appear?
I'm new to developing iOS applications and my school gave me approximately 5 months to develop an iPad application. I have no knowledge or practice on Objective C so since Flash Builder 4.5 allows the development of mobile applications (and I have experiences with Flash Builder), I decided to develop my application on Flash Builder instead.
Everything is going fine until I was told to include a SplitView in my application. I implemented a List on the left side of the application. Clicking on any of the list items will navigate the user to a to another view but i also included and retained the list on the left side of the new view in order to simulate a "SplitView".
Initially it felt as though it will do the job of a SplitView like how it does when I attempted it on XCODE but it doesn't look or feel natural. I found this video which shows that it is possible to create a SplitView on FB but I've cracked my brains and I really can't figure out how it is done.
