Flex :: Best Way To Validate A Complex Flex Form?
Dec 8, 2009
I have a Flex application that edits a moderately complex object, and I'd like to put some client-side validation in place on multiple parts of the editor.The editor is a set of nested objects:[code]The structure echoes the data model fairly closely, and the UI is what the project requires, so I'm not going to be too quick to restructure the classes there if I don't have to -- time is an issue too. What I want to do is have validators for each of the Component* instances that:[code]Show the validation tool tips and UI hints on the relevant UI element.Disable the SubmitButton when any part of the form is not valid(Optionally) provide enough information that I can display an error message in the form.

I have noticed two differences between spark and mx forms which are causing me some problems. It seems by default the mx forms are arranged to the label is above the form input item. In Spark they are arranged next to each other. Also the label in spark forms are bold by default.For example MX code could be
<mx:Form width="100%">
<mx:FormItem indicatorGap="0">
<s:Label text="label1"/>

I'm trying to come up with the optimal solution for validating IP addresses in Adobe Flex. My current solution is to use a regexp validator and look for dotted quad numbers, see code below. For some reason this will also allow an address like "1.2.3.4.5".
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="[URL]"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">
<fx:Script>

I have a DataGrid which uses an itemRenderer to display the items in a DataGridColumn. The ItemRenderer is created in actionscript and contains the following code:
public class PromptingColumnRenderer extends Label {
public function PromptingColumnRenderer()
{
[Code].....
In this DataGrid column, I require number validation on only the data with the type="NUMBER" field set. The problem is, when I try to declare a NumberValidator within my PromptingColumnRenderer actionscript code, the view recycles the renderer, and the NumberValidator attempts to validate non-numeric rows. What is the best way to validate only the rows with the type="NUMBER" field set?

I'm trying to understand if it is possible to generate complex PDF files with Flex. By complex I mean add images, styled text (font-family, weight, columns) layout elements with large degree of control and so on. I was looking at AlivePDF library but cannot understand if it can handle more complicated PDF generation than plain text.

I recently came into a situation when sending a nested object from Java to Flex via a HashMap the Objects were null. More precisely:final Map< Integer, List<String>> tempMap = new HashMap<Integer, List<String>>();would send the keys as integers but the values were all null.But when sending the same with String keys:final Map<String, List<String>> tempMap = new HashMap<String, List<String>>();the objects came thru.Are there any restrictions in BlazeDS serialization when using complex types as keys?

I'm a seasoned Flash developer and have just recently switched to Flex, but so far I've been having a hard time with creating the right kind of components. For instance, in Flash if I wanted to add a complex interactive menu, I would have a menu clip in the library, then export it for ActionScript, assign a class to it and add it to stage. How would I do something like this in Flex? It seems all I can do is expand the UI Components, and none of them is really suitable for what I want to do

I've bee following this site for a long time, and now I finally got a question on my own.
I'm trying (by ActionScript) to make a bunch of small circles form a complex shape e.g. a star or a windmill.
I'm planning to draw on circle and draw it to bitmap date, but I don't know how to place a lot of circles in the shape of a complex shape (or how to transform them into another complex shape).

Okay, there is something that I don't quite understand. I built a flash contact form in Flash CS4 and embedded the swf in my webpage using Dreamweaver CS4. I upload the files in my server but why it's not working? I created a test folder in my folder and it does work... (It doesn't work here) [URL] The problem is that I'm not receiving the information when the user enters and submits the information on the contact form. I do receive the information on the test link. I'm posting the Flash AS and PHP Code to see if anyone can point out any mistake that I'm doing.

I'm designing a data entry app that allows multiple entries to its subject. For example, a person might have received education from multiple institutions. Each educational entry is a form and app user can click on a button to add another entry, which is a blank but identical form.I figure it involves states and custom form components but not sure how everything fits together.

I have a form that is written in MXML that allows a user to create/add a User.I need to add a form that allows a user to modify SOME but NOT ALL of the fields for this user.The forms are so similar, I don't want to have to create two separate forms, one for Add and one for Modify.For example, in the Add form, the user specifies a user id. In the Modify form, the "user id" field is not editable.I'm wondering how I can initialize the MXML form (i.e. pass in a parameter?) so that it knows whether it is in the Add state or the Modif state.I know I can't do the following but this is what I would like to do (pseudocode):[code]
