Flex :: FSpark SkinnableComponent SkinDestructionPolicy

Nov 16, 2011

As a part of trying to tackle a memory leak in our application, we discovered that for every SkinnableComponent, the skinDestructionPolicy is set to "never" by default.This means that when using static skin parts, the skin is forever detained in memory.Furthermore, the override of a partRemoved() in the host component will never be triggered.Hence, event listeners we add in the partAdded() override are not removed, which effectively causes views and skins to be kept in memory.When doing a lot of view switches this is just not acceptable.[code]However, using the mx::internal way to circumvent this behavior seems rather odd to me.Documentation about this is scarce as well, so any ideas will be very welcome.

Flex :: What Event Is Fired When All SkinSparts Are Available In A SkinnableComponent

Feb 12, 2011

I'm (slowly) learning Flex 4 and working on skinning a custom component that extends SkinnableComponent. The component is all in ActionScript and essentially looks like this:

[Code]...

The issue I'm having is on NULL REFERENCES in the Constructor for the various SkinParts, because they're not created yet. I'm trying to find out when is the best time to access them to assign their .text values. I know I can override partAdded() and add the .text value as each part is added, but I'd rather just listen for some magic event that is dispatched when they're all available.I'm not sure whether or not it matters, but the accountName, accountNumber variables are assigned by using a repeater with a dataProvider on the host component. I'm not sure if that too has something to do with when the data is available to the AccountSummary component - which may also needed to be waited on. I was able to successfully use FlexEvent.CREATION_COMPLETE to assign all my .text values to the SkinParts, but is that the right event/best practice?

Actionscript 3 :: Determine If A SkinnableComponent Has Finished Adding Parts?

Jan 4, 2012

Does anyone know if there is a way to determine when all the parts of a SkinnableComponent object have been added? The context of this problem is the following:I have a custom skinnable component class which needs to update some of its parts (e.g. change some labels) once it has been created, meaning once all the skin parts have been instantiated and added.

Flex :: Reduce The Time Request Between Producer (Java) And Consumer (Flex) With JMS Message?

Jul 12, 2010

I 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.

Actionscript 3 :: Flex - Selection In Flex Datagrid Does Not Pass The ValueObject To SelectionChangeHandler Function

Aug 11, 2011

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.

Flex :: Override Child Node Controls In A Flex Tree Control?

Aug 20, 2010

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)" />
