What I've encountered is that the sort gets the element index out of sync with the dataprovider index, so while the size and positioning of the elements are correct, the actual display pieces in my item render, such as label text, are assocated with the incorrect element. @Evtim

I can't get into details publically, but if you'd e-mail me directly, I'd be would really like to get into more detail. I have other questions as well, such as, which of the two options you listed above would be appropriate/better for drag & drop support in the DataGroup container? Virtual layouts are something I came across a couple days ago and, if I can figure out how to implement it correctly, would really be beneficial. Depending on the view state, there could be hundreds of elements that wouldn't need to be rendered. @Evtim

Usually the layouts I've seen cache layout specific data in local (to the layout) structure instead of in the dataProvider, but probably your situation is different. It's easy to get access to the dataProvider and also to the data item that corresponds to a particular renderer from within the layout: The layout target property is typed as GroupBase, so you'd need to cast it to DataGroup like this: "var dataProvider:IList = DataGroup(target).dataProvider". Alternatively to get the data item for a particular item renderer you can either go through the dataProvider or do something like this: "var item:Object = IItemRenderer(target.getVirtualElementAt(i)).data". Note that when getVirutalElementAt() is called during layout it will force creation for an item renderer if the renderer didn't exist already, so you should be careful with that. Here's link to one very nice article about virtualization http://flexponential.com/2010/03/06/learn-how-to-create-a-simple-virtual-layout-in-flex-4/ Hi Jason,

The custom layout has the ability to see and set some properties of the items in the dataprovider for the container I apply the custom layout to. What I'm struggling with is that I need to access data in the dataprovider (ArrayCollection), to help me in the layout. For example, I store x-position, and width, as a part of the data in the ArrayCollection and I also need to sort the ArrayCollection source at various times, while I am calculating the y-position and the height. How do I get access the the data in the dataprovider for the container? I'm using a DataGroup container.

Totally going to use baseline alignment now. Don't really need the offset for most situations, but that's handy too! Thanks for sharing the code! Really cool.

If the issue is somewhere else, I'd encourage you to post at the Flex SDK forums with a small sample app, so we can take a look at it (http://forums.adobe.com/community/labs/gumbo/).

Thanks (using SDK build 10485) Hi Jochen,

I am having different issues with the TileLayout, I have a few list’s ontop of each other and there is a huge gap between each list as if the content in the list is not measuring the height correctly, this only happens when the list Orientation is TileOrientation.Rows, have you had the same problems?

Thanks
