If I have an XMLList object in Flex, what is the proper way to check to see if the list is empty? Should I just compare the result of myList.length() > 0, myList.toString() != "" or try another method altogether?

I want to check in my function if a passed argument of type object is empty or not. Sometimes it is empty but still not null thus I can not rely on null condition. Is there some property like 'length'/'size' for flex objects which I can use here.
View 6 RepliesI have a problem with XML filtering. [code]If there is only one result, trace is empty. If there are 2 results or more, they will be traced fine. Is it because one result is not an XML 'list'? If so, how do I get the results if there is only one match?

Unfortionatly this is returning me an empty XMLList.

View 1 Replieschecking an XML file for a specific node.
Example:
<vid
flv="videoName"
thumb="thumbnail.jpg"
title="Video Title"
[code]....
The first vid node contains a path to a logo graphic, I then need to check in my ActionScript if there is a logo there or not, and to do something if there is(display the logo) I can trace out the logo path so I thought I could run a simple if/else to check if there is anything in that node and if so to do something:
private function thumbOver(e:MouseEvent = null):void
{
trace("
");
[code]....
Now I've tried everything, but it will always trace out "Does have a logo" no matter what I do. I tried:
if (tabData[tabID].video[e.target.id].@logo == "")
if (tabData[tabID].video[e.target.id].@logo == null)
However I get the same results?

View 12 RepliesI have a button on stage which has a child menu movieclip and that movieclip has three submenu button children.On each of these 3rd level buttons an event listener draws a new container on the stage and adds a new movieClip holding various info.This all works nicely, but I cannot work out a way to get an eventListener on the menu buttons to check if the container already exists so I can then stop the button repeating the add container function. So, at the moment you can repeatedly hit any of these menu buttons and they will just continue to add info movieClip children.I've tried some nice Boolean commands that should work, but I think it's the nesting of the children/relationships that are not allowing me to get this to work.So, basically for arguments sake, let's say I only have one of each item... here's the nesting of children:[code]
View 14 RepliesI have 3 input texts on the stage.
money_input
percent_input
years_input
what I want after pressing the button (calculate_btn)is to get thees values entered from these input texts into 3 vaiables.
var $money
var $percent
var $years
and check if the inputs are numbers only not string not empty. I tried to convert the inputs to numbers to insure that they are numbers without making a function to check the inputs but always I get NaN when I entr value like 444bb;
ActionScript Code:
error_txt.text = "Enter some values to calculate your loan";
//--------Make the button listener----------//[code].........
I want to check if an input text field is empty. I only managed to do it this way;
mytext = textfield.text;

The problem with this approach is that I also want to exclude variables with whitespaces.
I tried; if(!isEmpty(mytext) )..... but that didnt work.

The following is my codes. This is still work in progress; so, you will see some functions with empty contents. Plus, this is my first Flex application; please bear with me. This is a quiz application that gets the questions and answers to each questions from a ColdFusion web service. There are three types of questions, True or False, Multiple Choice with single selection, and Multiple Choice with multiple selections. So, based upon the question type, the application would dynamically generate the appropriate amount of radio buttons or check boxes for the users to select. I got these working. The problem that I am having is, I am not sure how to check what the users have actually selected. In some other forums and posts on other web site, it said that I can use event.currentTarget.selectedValue to get the user selection. But when I actually do it, I got a run-time error saying, "Property selectedValue not found on mx.controls.FormItem and there is no default value." My question is, what do I need to do to capture the user selections?

View 1 RepliesIs there anyway of type casting an ArrayCollection to xmllistcollection or to xmllist or can we covert ArrayCollection to xmllistcollection or to xmllist?
View 1 RepliesWhat it says on the tin: I have an XMLList, and I want to find where in it a particular XML item falls. First index is good enough for my purposes. Note that I have no problem writing a function to do this by hand... but I was hoping that the API has something buried somewhere that'll do it for me. I didn't see it, though.

However this displays the datagrid with two rows, the first row has 1 in the Series column and then the two files crammed into the second cell in the same row. The second row is the same but has the number 2 in the Series column and the two series #2 files crammed into the cell next to it.If i do not use the nested data class i can pull the files using Series.file instead and all 4 of the files list correctly, however i do not get the Series number for each...
