[flexcoders] Re: Item Renderer focus on subcomponent in List
I took your example with the DataGrid and slightly modified it to extend a List. The example correctly shows a list and correctly tabs into the first itemRenderer ( rendererIsEditor=true and the MultiField editor is the Renderer). The shift works to tab back out of the first item as well. The error comes when i reach the lastname text box on the first editor and want to go to the second one. It throws a runtime error below. --- ReferenceError: Error #1069: Property text not found on DataGridMultiFieldEditor and there is no default value. at mx.controls::List/itemEditorItemEditEndHandler()[E:\dev\3.1.0\frameworks\projects\framework\src\mx\controls\List.as:2609] at flash.events::EventDispatcher/dispatchEventFunction() at flash.events::EventDispatcher/dispatchEvent() at mx.core::UIComponent/dispatchEvent()[E:\dev\3.1.0\frameworks\projects\framework\src\mx\core\UIComponent.as:9156] at mx.controls::List/endEdit()[E:\dev\3.1.0\frameworks\projects\framework\src\mx\controls\List.as:2181] at mx.controls::List/deactivateHandler()[E:\dev\3.1.0\frameworks\projects\framework\src\mx\controls\List.as:2397] at flash.events::EventDispatcher/dispatchEventFunction() at flash.events::EventDispatcher/dispatchEvent() at mx.core::UIComponent/dispatchEvent()[E:\dev\3.1.0\frameworks\projects\framework\src\mx\core\UIComponent.as:9156] at mx.controls::List/endEdit()[E:\dev\3.1.0\frameworks\projects\framework\src\mx\controls\List.as:2181] at mx.controls::List/commitEditedItemPosition()[E:\dev\3.1.0\frameworks\projects\framework\src\mx\controls\List.as:1893] at mx.controls::List/updateDisplayList()[E:\dev\3.1.0\frameworks\projects\framework\src\mx\controls\List.as:1013] at mx.controls.listClasses::ListBase/validateDisplayList()[E:\dev\3.1.0\frameworks\projects\framework\src\mx\controls\listClasses\ListBase.as:3279] at mx.managers::LayoutManager/validateDisplayList()[E:\dev\3.1.0\frameworks\projects\framework\src\mx\managers\LayoutManager.as:605] at mx.managers::LayoutManager/doPhasedInstantiation()[E:\dev\3.1.0\frameworks\projects\framework\src\mx\managers\LayoutManager.as:678] at Function/http://adobe.com/AS3/2006/builtin::apply() at mx.core::UIComponent/callLaterDispatcher2()[E:\dev\3.1.0\frameworks\projects\framework\src\mx\core\UIComponent.as:8565] at mx.core::UIComponent/callLaterDispatcher()[E:\dev\3.1.0\frameworks\projects\framework\src\mx\core\UIComponent.as:8508]
[flexcoders] Re: Item Renderer focus on subcomponent in List
I believe I found the problem. I need to rewrite an event to return multiple values from the item editor instead of the default 'text' value. I'll work on this and the tab should work I'm guessing. If it does not I will report back. Thanks for the help again.
[flexcoders] Re: Item Renderer focus on subcomponent in List
I fixed the run time error by writing a function to pass the two text
box variables back to the data provider. (ItemEditEnd=func(event);)
Fixed it. So now I can tab into the List's first component but once
focus is on the first renderer I can only tab and shift between the
two boxes in the first renderer. It's like the focus is stuck there.
Any ideas.
Here is the code I added for the ItemEditEnd function. Not sure if
that messes up tabbing and focus.
---
public function endEditRenderer(event:ListEvent):void {
event.preventDefault();
list.editedItemRenderer.data.first=
Renderer(event.currentTarget.itemEditorInstance).firstName.text);
list.editedItemRenderer.data.last=
Renderer(event.currentTarget.itemEditorInstance).lastName.text;
list.destroyItemEditor();
list.dataProvider.itemUpdated(list.editedItemRenderer);
}

Alex, Thanks a bunch. Days of frustrated work make you overlook whats staring you in the face sometimes. In searching for answers I've noticed your work and responses across the flex world. You do excellent work in you blog and responses helping us 'beginners' out.
[flexcoders] Item Renderer focus on subcomponent in List
I've got a List of Item Renderers that contain inputs and a combobox. When the List gets Focus, the item renderer displays its default, text input focus instead of the item renderer. How can I get focus to be set on an item renderer component instead of the whole item renderer itself?
[flexcoders] Re: Item Renderer focus on subcomponent in List
Thanks that has got me on the right track. Not sure how I overlooked that. Ive got it to focus on the first item inside the item renderer. I now have a problem tabbing to the next item renderer in the list or outside the list. I get a 1069 error. I think I have to modify the keyfocuschange handler but I'm not positive. Any thoughts.
[flexcoders] Re: Item Renderer focus on subcomponent in List
I read and followed the example on your blog about tabbing between two text inputs in the datagrid. This is similar to that, but two text inputs in a render of a list. I don't believe the List functions the same way and I am having trouble transfering what I learned on that to my situation.
