[flexcoders] Selecting an Item Programmatically after Adding it to List
Thought I'd run this by everyone. If you have a List, whose dataprovider (arraycollection) has an ac tive sort on it, how do you select a new Item immediately after an addItem call, programtically? I can't predict what slot it's going to end up at due to the sort. It used to be easy before the sort (you just select arraycollection.length-1) Do I need to resort to: Using the collectionChange event, and then in the handler function, looking at the object in event.items[0], and then searching the arraycollection for the label field? Thanks, Steve

While your code is technically correct (thus it works), since you are
changing a [Bindable] property your compiled code will dispatch
tempArray.length change events as you iterate through the tempArray.
You can simply assign the event.result value to arrayDP.
[Bindable]
public var arrayDP:Array;
private function getDataListener(event:ResultEvent):void{
arrayDP=event.result as Array;
}
or alternatively:
[Bindable(event=DPChange)]
public var arrayDP:Array;
private function getDataListener(event:ResultEvent):void{
var tempArray:Array = event.result as Array;
for (var i:int = 0; i tempArray.length - 1; i++) {
arrayDP.push( {name:tempArray[i].name,id:tempArray[i].task_id});
}
dispatchEvent(new Event(DPChange));
}
Use the [Bindable(event=DPChange)] metadata tag, where you are telling the
compiler that you'll be dispatching the change event, and dispatch it once
you've iterated through the result array.
This might be helpful if you want to do client side processing on the data
before displaying it.

[flexcoders] calling removeListener on a popup
I have a mxml component based on TitleWindow that's used for a Popup. Nothing new there - big yawn goin your way. I also have an addEventListener called on the object (so I can dispatch a custom event): --- win = EditTaskBox(PopUpManager.createPopUp(this, EditTaskBox, true)); win.taskText.setFocus(); . . win.addEventListener(taskInputText, newTaskDialogBoxHandler); -- So obviously, you want to call removeListener when you're done with the dialog, so I call removeEventListener in newTaskDialogBoxHandler(), in main.mxml, after I use the information from the custom event. win.removeEventListener(taskInputText, newTaskDialogBoxHandler); However, in the case of *cancelling* the dialog box, do I need to dispatch an event in this case as well, from within the component.? In my customer TitleWindow component, called EditTaskBox.mxml, for the closeButton handler, I call PopUpManager.removePopUp(this); It's not like you can do: removeEventListener(..) here, since you're in a static component,right? Looks like I need to just create a meta declaration for a custom event, but obviously don't need a custom Event class or anything. Just verifying this. Thanks Steve

[flexcoders] Best Pattern for a Complex Application Options/Settings Box
On the verge of creating a non-Trivial Dialog screen/box for my app where a User creates categories, chooses settings (warn when deleting), Default behaviour, etc... It'll have 3 tabs. I'll be pulling the settings from a MySql Options table. Is it common practice, even for Complex dialog's, to: - just use the usual TitleWindow with createPopup, which is commonly used for more trivial input your name stuff ? - *not* pull the SQL data from the Options table, until a user actually launches open the Dialog Box. ( It's possible to, on App init(), to load the data into an array, so that the dialog opens quicker, but a user may use the Settings module once every 5 uses of the App ) Steve

( The most hopeful sign that this is possible is the itemFocusOut event, but I can't use this, anyway, due to the editable value of my renderer (editable=false)) So my next best attempt to accomplish what I'm trying to do, is to get the last item that was just selected (the selectedIndex) before the user changed it.

This sounds vague, but basically it's: My Zendamf remoting object has a fault=faultListener(event), which has an Alert.show statement.

I have a Result event set up, but the resultListener function never gets called. It's not like I can do this: if (!succeeds) then display fail, like you can on a normal php/mysql app. And I just want to avoid having to go the reverse logic route to resolve this: When the Result event gets called, do an Alert.show().

[flexcoders] Getting rid of the Scrollbar in the List Item
After a marathon Google-fest/Adobe Help Site search, I have not been able to figure out how an elegant, best-practice, or any other way to get rid of the horizontal scroll bar that appears when some text doesn't fit into an Item. You probably have been through this before, but I'll show you the image of my List control: http://www.lucidrhino.com/images/list_image.JPG Should I simply, in my custom ItemRenderer, just check the length of that field (which is data.description) and simply truncate it to some short arbitrary length ?

[flexcoders] Accessing a child component,, specifically a checkbox, from an mxml component
First of all, thanks for the responses concerning the List Items-detecting. Hopefully those responses made it. I'm on the Probation list where it takes a while to get approved. -- This next particular issue is really disturbing me, but it's probably pretty simple. I have a mxml file containing a custom component, called EditTaskBox. It's a TitleWindow and it's in my components folder. In main.mxml, I have this to create a custom popup: var win:TitleWindow = TitleWindow(PopUpManager.createPopUp(this, EditTaskBox, true)); ( I need to set win.title = something, so I cast the return to a TitleWindow type. ) There is a checkbox in that component, a nested child, but I can't seem to control it in Actionscript from main.mxml. I can't use EditTaskBox.mycheckbox, because it Understandably complains with possibly undefined project through reference with static type class. And trying win.mycheckbox doesn't work of course, either. My googling turned up empty. Hoping someone knew about this. Steve
[flexcoders] Detect if any of the Items on a List are Selected - thought it would be easier.
The only property I could find, from the Flex docs, that tells you whether your
List control has anything selected is: isItemSelected().
And this takes a parameter that refers to a specific item. So before my Delete
button handler, I check if any item is selected with the following:
private function deleteHandler() {
var bDoesNotHasFocus: Boolean = true;
var len:Number = projectList.dataProvider.length;
for (var i:int = 0; i = len - 1; i++) {
if (projectList.isItemSelected(projectList.dataProvider[i]))
{
bDoesNotHasFocus = false;
}
}
if (bDoesNotHasFocus)
return;
// the code to delete
}
Is there a better way, anyone?

[flexcoders] Best way to call SQL LAST_INSERT_ID through Zend Amf
Hi, I'm mostly a newbie and am writing a simple Flex app. So far, just a List box, where I am renderering a Checkbox and a :abel field, for a simple To-Do utility. I just added the Add New task functionality, and it's working fine, using the addItem method to add the new object to the List after saving the record to DB via ZendAmf. However it has occurred to me that I need to go back to the database immediately after, to get the record Id via ZendAmf so that the Flex List's new Item has the actual database id. Is it best practice you think to create a ValueObject class for just this integer - the task_id key field - or should I simply just use the existing Value Object for the entire object that represents an entire Task and obviously, just use the task_id field to pass it from db to flex.
