ActionScript 3.0 :: Accordion Component Null Reference?

Apr 23, 2010

I've got an mx accordion component that I want to populate at runtime. However, the first box will populate fine, but all the others return null reference so I can't access them. Does this have something to do with which one is currently selected? I'm creating my accordion:

<mx:Accordion x="398" y="207" width="331" height="250" alpha="1.0" borderStyle="solid" borderThickness="0" cornerRadius="10" fontFamily="Arial" color="#000000">
<mx:VBox label="EDITOR'S NOTES" fontSize="10" width="100%" >

Jul 10, 2009

I have an accordion component on my stage and I really do not even know where to start to do .I found this code on the Adobe help pages and it causes the movement of the accordion to bounce... which is great... but my problem is populating the accordion with the data.

Quote:

import mx.core.View;
import mx.transitions.easing.*;
top_acc.createChild(View, "first", {label:"FIRST", icon: vt[i]});[code]........

My accordion is called "top_acc".I have three(3) labels... (FIRST,SECOND, and THIRD) Within there i would like arrays to be displayed for the select label.My arrays are defined and when i trace them i get exactly what i am looking for... the format of the code to add an array to my accordion...then upon selecting the item in the array displayed i would to be able to display that same array value in a text box called "my_selection" ....also the amount of items in the array are not static and change day to day..

ActionScript 3.0 :: Use The Scroll Pane Component - Getting An Error Error #1009: Cannot Access A Property Or Method Of A Null Object Reference?

Oct 1, 2007

I am trying to use the scroll pane component and I am having a few teething troubles. I have a scroll pane as a child object of a movie clip which is essentially a 'page', if I display this page it works fine and the scroll pane does too. If I then remove this page from the display list, go to another page and come back by readding it to the display list, I get the following error, even though nothing else has changed:

TypeError: Error #1009: Cannot access a property or method of a null object reference.at fl.containers::ScrollPane/fl.containers:ScrollPane::endDrag()

The scroll pane is still visible and works correctly, but ideally I'd like to stop this error.

Flex :: 4 - Null-component - Checking If The Cancel Button Component In The Child Component?

Jun 23, 2011

I have a component "child" which has a cancel button. Now this component is placed in a state called "newChildComp" I also have another component called "parent". In the parent component, i have a button that dispatches an event. Here is the event code:

[Code].....

so, basically,i am checking to see if the cancel button component in the Child component, while i am still in the parent Compoent, was clicked, if it was clicked, call the cancelButtonHandler. The problem is by the time the addNewChild handles the event, that cancel button was still null. My question is how do i solve this without using the itemCreationPolicy on the cancel button?

ActionScript 2.0 :: Passing Variables - Movie Clip & Accordion Component?

Apr 4, 2010

I am trying to build a Calculator used in health circles to project next year's profit and loss etc. I am using flash cs3 and actionscript2.My flash project is based on accordion component with 6 child panes, each pane having a movie clip with input text, dynamic text etc.I have a couple of push buttons that has click eventhandlers taking care of calculations . All the calculative functions are in the actions layer frame 1.I need help in displaying the same calculated fields as dynamic text in a new movie clip in another layer before printing the same movie clip.The present situation is like this, I am able to calculate all the fields, but when i click a button to show a new movie clip with all the calculated fields, all the variables are displayed as "undefined".

the dynamic variables in the new movieclip is referenced correctly i guess, i use pp_acvcfy = myacc.overheads.acv_cfy; where myacc is the accordion component , overhead the child pane and acv_cfy the dynamic text inside the pane 'overhead'. pp_acvcfy is the dynamic text in the new movie clip. Please help

Flex :: Accordion Component - Show The Whole Content Without This "white" Rectangle When It Loads?

Nov 24, 2011

I've an Accordion component in my Flex application and works great, but I found a little glitch in its behaviour.While one of its menus is opening, it shows a white rectangle and, when it completely loads, it shows me the content. But I want to show the whole content without this "white" rectangle when it loads.For example:

Image 1: My Accordion is ready to use

Image 2: I want to open another submenu, so while it's opening, a white rectangle is shown (I was really quickly to take an screenshot)

Image 3: Recently opened submenu is fully loaded.Here is my source code:

ActionScript 3.0 :: Null Reference From A Function?

Jan 30, 2012

I thought I understood this stuff by now; the objects within a function are onlyaccessible within that same function, unless you return it to whatever called the function.However I dont think that you can do that for a function called with an eventlistner, so I set up what I thought was a global variable and set its contents within the function, thinking that the contents would be accessible later:

ActionScript Code:
var bmpd:BitmapData;
var URLReq:URLRequest = new URLRequest("sample.jpg");

Actionscript 3.0 :: Cannot Access Null Reference

I have a working MP3 player I did last year and I am re doing one using classes. So i am coping and pasting code, changing what needs changed and I can not figure out why it works on the other one, but not here.I am getting the error: Cannot access a null reference.. so its not finding something. I traced out what I have and found out that its not getting passed the function playSong(). When the play button is pressed, it fires off playSong(); From there, it SHOULD fire off soundCompleteHandler(); Its not making it to the soundCompleteHandler();[code]

My movieclips are being nulled when moving between scenes, they are created on the stage and accessed through as3. I have login screen with three button, one logout, one exits the system and the other takes them to the next scene. When going back to the login scene, and trying to access movieclips like add eventlisterners etc... it comes back with null object reference, claiming that my buttons which are on the stage are null and sure enough if I debug they are. Any reason why my movieclips are being made null when moving between scenes?

ActionScript 3.0 :: Null Object Reference Text ?

Aug 26, 2010

I have a movieclip that I add to the stage and Im trying to reference a input text field on the second frame.When I trace the textfield on the first frame via the constructor it returns object textfield correctly.When I hit the enter button to go to the second frame where I will need to use password... I get a null when tracing. I can see it, I can write in it and no matter what I do I cannot seem to reference it.

Code:
public function Registration():void
{
trace(this.usernameField); //returns textfield correctly[code]...

In case you need the parent of registration its just the document class and I create registration like this..

Code:
var registration:Registration = new Registration();
addChild(registration); //ive also added it to the stage w/ no luck

ActionScript 3.0 :: Check If The Value Returned Is A Null Object Reference?

Jul 10, 2009

I have a form where a user can select up to three radio buttons and click submit. however if they don't select a radio from one of the groups (they dont care to answer the question or just missed it) the value of the radio button (I think) is null and gets returned as such using this code:
 
function Question1():Object{    return RadioButtonGroup(Q1R1.group).selection.value;}
 
Then, when they hit the submit button it sends the values to the database. This works fine, but only if they select a radio button for each group. If they missed one I get the following error:
 
"TypeError: Error #1009: Cannot access a property or method of a null object reference.    at mid_fla::MainTimeline/Question1()    at mid_fla::MainTimeline/clickHandler()"
 
When I did a trace on the value of Question1() it returns function Function() {}
 
how to check if the value returned is a null object reference or whatever and give it a default value if it is?
