Re: [flexcoders] Capturing an event in a separate component
Thanks Alex. I was able to do this only by using the code-behind technique
from labs.adobe.com, but at least it works!

Given this scenario:
Parent Componet
Child1
Child2 (child of Child1)
Child3 (child of Child3)
and Child3 dispatches an event, how can I make the parent see that
event without having to pass it up between each child? I've made the
event bubble, but I can't seem to make the parent see it.
I can't seem to get the syntax for the addEventListener correct. Thanks

[flexcoders] Defer a databinding update
I've got an xml document that I've finally figured out exactly how to databind every element. (I don't get the element is not an IEventDispatcher error ! :) ) The problem is now that when, for example, you're on tab 3 line 5 and you input a value, Flex needs to redraw everything on the screen and loses the tab focus. You stay on the correct tab, but there's a noticeable pause while it redraws and the focus indicator goes away. Is there any way to defer this, or even halt it until you specifically call it? Thanks

believe me, I've tried to attack this problem from a number of ways :)here's the quick description:My form design:Policy 1: accordionDivision 1: accordionState 1: TabVBox

Whendebugging,Icanseethatthevbox'srepeateritemnowreflectsthechangedXML,butthescreenisnotredrawntoreflectthenewlineforthecode. My first plan was to just reset the dataProvider for the the entire form. Bad idea, it causes the whole form to redraw and loses the current location within the form.

Yes, you should probably back up a little and think about what you are trying to do.
Directly accessing elements of data-driven controls is usually a bad idea, mainly because the controls re-use the visual elements when you scroll.

[flexcoders] Am I expecting too much from data binding?
I've got an xml file that I read in as e4x format and create an interface from using repeaters. The interface looks like this: Accordion - Policy Accordion - Division TabNavigator - State Repeating Rows of classcodes Button to add a class code to the current state I've got the logic written so that once the button is pushed, a class code is added in the correct section of the xml document. This alone will not spark a change in the interface. I explicitly have to reset the value of the top databinding variable (an xmllistcollection) to a new xmllistcollection based on the e4x xml variable. This has the nasty side effect of resetting the interface to accordion 0, accordion 0, tab 0. Is this the way it works, or am I missing something Thanks -- Marlon -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!

[flexcoders] warnings on XML binding.
I'm trying to figure out why I get a ton of warnings when using
databinding to an XML variable. Here's the pertinent snippets of code
below.
mx:HTTPService url=assets/payroll.xml resultFormat=e4x
id=payrollXML result=payrollXMLHandler(event)/
private function payrollXMLHandler(event:ResultEvent):void
{
payrollXMLVar = event.result as XML;
wcPayroll = new
XMLListCollection(payrollXMLVar.policy.(@type.toString()=='wc'));
}
As soon as the 'wcPayroll = new XMLListCollection...' line runs, I get
these warnings in the FB2 console.
warning: unable to bind to property 'type' on class 'XML' (class is
not an IEventDispatcher)
warning: unable to bind to property 'name' on class 'XML' (class is
not an IEventDispatcher)
warning: unable to bind to property 'type' on class 'XML' (class is
not an IEventDispatcher)
warning: unable to bind to property 'name' on class 'XML' (class is
not an IEventDispatcher)
I get more as the tabs, repeaters, and accordions render also. I
think a side effect of this is that additions of nodes to the
underlying XML object are not reflected in the UI. Unless I
explicitly set wcPayroll = new XMLListCollection again, I will
not see the changes. Of course, if I set that again, I lose the
current location in my tab navigator. Help! Thanks!

Re: [flexcoders] Fwd: Pre selecting a combo box
Thanks Shannon, that did the trick. It looks relatively familiar to the way you do it with _javascript_. I really thought there would be an easier way to do it. I guess you could extend the component to include a method that would do that same thing though.

Here's what your code should basically look like:for (var i:number=0;imyComboBox.dataProvider.length

myComboBox.selectedIndex = i; break;

I've got a master detail form that works so far except for a combo box that's giving me fits. The combo box is populated from an xml file that contains a company id and company name relabeled with the label and data headers. The combo box populates correctly and I've verified that it returns the correct company id. Now, for existing users, I want the combo box to automatically go to the correct company they're assigned to. The user object has a company id. I don't believe that I can do it with binding since it's expecting a selectedIndex vs a selected data value. I've been experimenting around with trying to loop through the objects in the combobox, but I haven't had any luck doing so yet.
