问题 I have a problem when I try to access to a webservice from a mobile application. When I try the address of the webservice on my browser, it works, when I try in my application on the emulator of Flash Builder, it works. But when I try it on my phone, it doesn't work! I have access to the web in my application. I just create the webservice in a view in MXML. <?xml version="1.0" encoding="utf-8"?> <s:View xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" title

问题 I remember in Flex 3 text width/height could be calculated (not the text UI component but the text itself): new Text().textHeight; or new Text().getTextField().measuredHeight; Does anyone know how can that be done in Flex 4 with its Text Layout Framework now? Thanks. 回答1: I've found an answer myself. If someone has any better ideas - you're welcome. I use to assume that width of text content is not so important cause each time the size changes the value used below are updated. So I check the

问题 What are the advantages of migrating a Flex 3 app (Java backend, BlazeDS, Spring, Hibernate) to Flex 4? One of the biggest advantages of Flex 4 is design. Assuming that design / UI isn't a big driver for the business right now as compared to performance, what are the other factors we can highlight? We have implemented Cairngorm and Swiz on the App (with a gradual "roll out" of Cairngorm planned for the future). Any opinions? Thanks, Sri 回答1: Swiz AND the annoying car-horn? I absolutely love

问题 How do you check for JSON child node key existence using hasOwnProperty (or other methods) in Flex 4.5? The hasOwnProperty method can check for JSON key existence but this seems to only work with top level nodes in a JSON, and not the child nodes. For example, if you have JSON structure like this (in a readable form, sans the JSON syntax), you can check for the existence of callresponder.lastResponse.hasOwnKey("Location") , but there seems no way to check for Location.VenueName for example or

问题 I have a spark list, which is based on a dataProvider. As the application runs, the data in the dataprovider can change, and also the dataProvider can be swapped for a different one What I need to do is make sure that something is always selected in the list (unless it is empty) 回答1: You simply have to set the property requireSelection of your list instance to true . In MXML, it would be: <s:List id="myList" requireSelection="true"> 回答2: After setting its data provider ( or whenever is

However this is apparently beyond me and after wrestling with my inability to do so for an hour+ I'm posting it here :D So my transition block looks as follows <s
