I'm trying to build a collapsible panel in Flex 4. I thought I'd use s/thing like this:

But that throws an error: Instantiation attempted on a non-constructor. I grabbed the flexlib zip for flex 4 but I'm still getting that error.
Is there another way to create a collapsible panel in a control bar?
I have flexlib WindowShade component in repeater in my Flex + AIR application.
<mx:XML id="mainMenuXML"><items>
<item value="abc" />
<item value="xyz" />
<item value="lmn" />
</items></mx:XML>
Now in button1 click handler I am appending child in XML(mainMenuXML) resulting adding one more windowshade instance. But the problem is it opens all the windowshade instances. I need to maintain the opened states after adding a new windowshade instance.
For example:
Initially I get 3 windoshades with labels: abc, xyz, lmn all opened.
Now I close the xyz windowshade instance(by clicking on the header)
Now I click on button which appends child in mainMenuXML and also add a windowshade instance with some label "pqr". But now I see all the windowshade instances opened.
But it should be like abc, lmn, pqr should be opened & xyz closed(property opened="false").
How to maintain the opened true/false state of windowshade instances. I tried to add a property in dataprovider Bindable to opened property of windhowshade but didn't worked for me.
I am trying to to use FlexLib in an MobileFlex Project with Adobe Flash Builder 4.6. For learning-reasons I am trying to create an iPad-Version of the ScheduleViewer1_Sample.mxml.
For some mysterious reason - at least a reason I don't understand - it's not working with the latest flexlib (2.6-M2). With the former Version (2.5 - latest on googlecode) I just had to change the used namespaces and it worked like a charm.

View 1 RepliesI'm trying to use a flexlib schedule viewer in my application. I want to have it so that when I click on a scheduled event, it calls a function in my main app (that will allow me to edit the event). But there doesn't seem to be any specific function for anything like this built into the class ie no event dispatched when I click on an event.
I can use the 'click' function to detect that the item has been clicked on.. and have tried something like this:
[Code]...
This method isn't very reliable because if it only works the first time.. once an item is selected, it stays selected so all following clicks on the item fulfills the condition.
Is there any way to determine whether an event was being clicked on? Or do I have to extend the component and add some sort of clickEvent when an event is clicked on.
I recreated this example of using Base64Image but it does not work when ran locally, only when I load it from a web server. Is this expected and can it be done so that it works locally?

I want to be able to set it up and run it in flex builder and play with it for learning purpose.
I tried to use the import project option by pointing to the flexlib directory but it did not work - I think thats because the source by default does not have any .project or properties files.

View 1 RepliesI have implemented application client-server with spring blazeDs message services using JMS message destination. The idea is a producer declared in Java send message using activeMQ and consumer declared in Flex receives them. I have configured the AMFChannel with a polling interval 0, but I have seen when the consumer subscribes to the destination in Flex, the time request can be of up to 3 seconds.

I checked the fiddler and found that for the first request authorization header is present but for the subsequent requests which is requested to load the .js, css & images the authorization header is not added. This is the reason I am getting the auth dialog.
Is there a way to add authorization header to the subsequent requests as well?

I have a TabNavigator, and each tab is a Module. One of the modules is labelled Units and the full code of the module is posted in this post. There are several problems:
1) Forms are not populated with data from the datagrid selection.
2) Selecting a row and clicking delete gives the very-common error: TypeError: Error #1009: Cannot access a property or method of a null object reference.
A trace on the valueObject unit within the selectionChangeHandler function gives NULL. Why? Note: In other modules (other tabs of the TabNavigator), I have DropDownLists populated with units. This means that the valueObject Unit is defined in the other modules. However, valueObjects should be private to modules, and not shared.

I am working on a grid example in flex using advanced grid control. I know we can easily group data by specifying the field name. At the group node level, other than the gorup name I want to be able to show data in the rest of the cells ( calculated data ) and I am looking for some dataRowBound event or similar to be able to hook some data in it.
Example: Grid displaying list of towns grouped by state. At the group level ( for each state) I want to show the total number of towns in each state. Here how can i show the total number in the town column.

I am writing a Flex application for use on a private intranet with no external Internet access. I want to use Google's 3D Maps Flex API, but it must be connected to the internet to download map tiles on demand.

I am currently developing a dynamic LineChart in FLEX 4.I am implementing a Tree control next to my LineChart, which will filter the LineChart dataprovider and lineseries. The tree control has several branches and ultimately 5 children (leaf nodes) at the bottom of the last branch.I need the leaf node/children to be displayed as checkboxes inside the tree control.As I understand,this will require overrides in the TreeItemRenderer class.This is where I am a little confused on how to implement that.Currently I can distinguish between leaf and branches using this code, in my main MXML component.I added this because it may be helpful to some beginning FLEXdevelopers, such as myself, who cannot easily find this functionality documented well:
private function treeClick(e:ListEvent):void {
_selectedItem = Tree(e.currentTarget).selectedItem;
if(mainTree.dataDescriptor.isBranch(_selectedItem)) {[code].....
I am looking at the TreeItemRenderer override class from the following example here: In the example, they override the "createChildden" super function to add checkboxes to the tree control.My question is, can I override the createChildren function directly in my MXML component, and not have to use an entire class file to override this functionality? Must I re-invent the wheel to do this?Also, how can I distinguish that my treeItem is a leaf node and not a parent, in the override function? I only want to add checkboxes to the leaf nodes, how can I differentiate? The following example adds checkboxes to all branches and leaf nodes, but I want to add checkboxes only to leaf node/children. How would you approach that?
override protected function createChildren( ): void
{
super.createChildren( );[code]............
Here is my tree tag:
<mx:Tree id="mainTree" dataProvider="{treeData}" itemRenderer="TreeCheckBoxItemRenderer" labelField="@label" showRoot="false" width="100%" height="100%" itemClick="treeClick(event)" />
My company want to develop an online multitouch scrumboard for our scrumteams. We are still in doubt between flex and silverlight as platform for the application.
