[flexcoders] DragEnabled causing Error 1010

[Mike Weiland]

Hi all,

I have a situation where I have a tilelist set to allow the dragging of it's
images to another tilelist. It works fine if the items are dragged one at a
time. However, if multiple images are selected and dragged then I get an
error 1010. Here's how to reproduce it:

1. Go to: http://tours.aspentreemedia.com/busted.html
2. In the tilelist select all the images
3. Drag them to the horizontal tile list.
4. You should get the following error:
TypeError: Error #1010: A term is undefined and has no properties.

If I drag a few at a time I can't get the error or if I select all items and
then scroll back up and then drag and drop it will work! Also, if I don't
enable DragMoveEnabled the drag and drop works, but that's not the behavior
I want.

Smells like a bug to me,

Mike Weiland

[flexcoders] Tree: Resetting openItems after dataProvider change

[Oliver Merk]

I've been wrestling with this for over a week and haven't found a
solution to this problem. Hoping someone can help.

I have a tree control that, at runtime, changes its dataProvider. In
this case, I'm switching languages and the dataProvider format is
XMLListCollection. I'd like to restore the open items of the tree
after the dataProvider has changed. I tried using the openItems
property, but openItems stores a list of XML objects from the original
dataProvider.

When the provider changes, the XML objects are of course different,
and trying to reset the openItems property fails. What I really need
is an "openIndices" property that is not tied to the XML data in the
provider.

The example Adobe gives
(http://www.adobe.com/devnet/flex/quickstart/working_with_tree/) is
not helpful since they switch between two dataProviders with the same
content and they're using an ArrayCollection (I'm using an
XMLListCollection).

I've tried walking the tree but since the new Flex 2 tree control
limits direct access to nodes, I could not find a way to detect the
open indexes of the tree directly.

Any ideas?

Thanks,
Oliver

[flexcoders] Re: Cairngorm Store, Best Practice Question: Containers

[Bjorn Schultheiss]

If your considering optimization it is important to understand how
your containers measure function works. I suppose if you have
containers 15 levels deeps or more with each having relative,
perecntage based values set, it might tax on slower processors. 

Tims and Ralfs advice is gold.
Just don't add any unnecessary containers and be aware how the
containers handle there measuring.

[flexcoders] Re: Cairngorm Store, Best Practice Question: Containers

[Tim Hoff]

Hi Kenny,

I agree with Ralf.  For larger projects, that use a modular structure,
there will be nesting of containers (components).  If you're worried
about performance, opt to use the lightest-weight container that is
necessary for the case (i.e. Canvas over Panel).  Where possible, you
can also set the width and height of containers and controls explicitly;
to reduce the calculations for measure and layout.

[flexcoders] Re: ItemRenderers and Events

[Matt Maher]

Wonderful reply Tracy. Thanks. Bubbling the event, that's the perfect tip.

As for not being able to walk the items in the list, that seems
counter intuitive to me, but okay. As long as I know the behavior I
can find a way and stop pulling my hair out wondering why I can't do
what Flex doesn't do in the first place.

Thanks a ton for the clear and very helpful reply.

Re: [flexcoders] How to align text in middle in a row ?

[dorkie dork from dorktown]

This works with List components and it should work with the datagrid.

Re: [flexcoders] Cairngorm Store, Best Practice Question: Containers

[Ralf Bokelberg]

What would be the alternative? I mean, if you need nested containers, you
need them. Our projects are nested 15 levels deep and more and i never found
that performance is bad. Premature optimization is the root of all evil :)
Cheers,
Ralf.

  Hi all,

Just a quick question about the Cairngorm Store. It is my
understanding that the application was constructed to showcase some
of the best practices in developing a Cairngorm project.

With that in mind, I took note of some container nesting in the
Store. I am a little confused because in some performance articles it
specifically advises against the use of nested containers.

I ask because I have some instances where a ViewStack in a panel
would be ideal: For example, I have an application where access level
controls the view inside a Control Panel. I'd like to bind a
ViewStack selected index to the access level in my ModelLocator.

I also would like to utilize a little nesting with Panels inside a
VBox, etc.

What's the jury say on this? Is there a happy medium on the subject?

 Hi Arpan,

There is an the attribute which is named "textAlign" for the Object
"DataGridColumn" .
Is that the information you need?
