Internally, we're doing an instance check, not a test of properties to see if they match. Unless you've handed the list an array of things that are the same instances as they are in the dataprovider it won't match.
I can't get to the GIF for some reason. Are you saying that myAC[0] was modified so that the sub AC was removed? I'd go find out what actually got changed. -Alex ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of qnotemedia Sent: Wednesday, March 14, 2007 5:55 PM To: [email protected] Subject: [flexcoders] Re: Getting "selectedItems" to properly *select*... --- In [email protected] <mailto:flexcoders%40yahoogroups.com> , "Alex Harui" <[EMAIL PROTECTED]> wrote: > > Arrays in Flex and Flash are not watched for changes.

I assigned a findItems() function to a temporary array, arTemp. The function returns an Array of items found. The very next line is myGrid.selectedItems = arTemp. As mentioned in earlier posts, the items in this "found" array have precisely matched data to the dataProvider of the grid, and the selection still doesn't occur, without any errors either. The *only* difference between the two is the "@123456" following the Array description in the debugger. At least I have something that works (three posts back), but now I'm running into a similar problem in another area of my app, and I'd like to move forward with this thread... I have another popup with two grids. Grid A has a multi-level ArrayCollection. i.e.: myAC[0].something myAC[0].somethingElse myAC[0].anotherAC[0].anotherSomething myAC[0].anotherAC[1].anotherSomethingElse myAC[1].something ...etc... When the user clicks on Grid A (not multi-select), Grid B's selectedItems is populated with the second-level AC "anotherAC", like this: gridB.selectedItems = gridA.selectedItem.anotherAC.source And it works! BUT!!! When I select another item and come back to the first one, the anotherAC level has disappeared without a trace! It disappears from all bound ACs. WTF?! And BTW, I additionally tried the findItems() function as mentioned here. The same problem happens in that nothing is selected. Again, I've put together a gif to express my anxiety: qnotemedia.com/dissapearing.gif ...this is a before and after shot. On the left is before anything has been selected, and on the right, is immediately after a selection has occured. On the right side, notice that the dgAllRoles.selectedItems is correctly populated, but that both the dgSelectedNames dataProvider AND the original AC, selectedDevTeam have had thei second tiered item "collectedRoles" completely dissapear. Crossing my fingers that someone can understand this... - Chris
