If the DG thinks the renderer needs an update because its size may have changed, it will refresh all renderers. Maybe when you use the slider a second time the slider/renderer thinks it needs a re-measure. Also note that renderers are recycled so the second time around the renderer may not be in the state you expected and some child got re-parented or removed some other way.

I have an inline item renderer, bounded to a data source, which is an array collection of objects. These objects are used to dynamically display controls in a datagrid. Everything seems to work fine for awhile. I can slide the slider down and up and down, but when I try to slide it back up the second time I get the following error: RangeError: Error #2006: The supplied index is out of bounds. at flash.display::DisplayObjectContainer/getChildAt() at mx.core::Container/getChildAt() [C:\dev\flex_201_gmc\sdk\frameworks\mx\core\Container.as:2369] at mx.core::Container/removeChildAt() [C:\dev\flex_201_gmc\sdk\frameworks\mx\core\Container.as:2333] at mx.core::Container/removeAllChildren() [C:\dev\flex_201_gmc\sdk\frameworks\mx\core\Container.as:3429] at DynamicAssertion/loadControl() [C:\software\application\weka\BuildingCharacterization\DynamicAsserti on.mxml:45] at BuildingCharacterization_inlineComponent1/set data() [C:\software\application\weka\BuildingCharacterization\BuildingCharac terization.mxml:695] at mx.controls.dataGridClasses::DataGridBase/mx.controls.dataGridClasses :DataGridBase::makeRowsAndColumns() [C:\dev\flex_201_gmc\sdk\frameworks\mx\controls\dataGridClasses\DataG ridBase.as:650] at mx.controls::DataGrid/mx.controls:DataGrid::makeRowsAndColumns() [C:\dev\flex_201_gmc\sdk\frameworks\mx\controls\DataGrid.as:1293] at mx.controls.listClasses::ListBase/mx.controls.listClasses:ListBase::s crollVertically() [C:\dev\flex_201_gmc\sdk\frameworks\mx\controls\listClasses\ListBase. as:5467] at mx.controls::DataGrid/mx.controls:DataGrid::scrollVertically() [C:\dev\flex_201_gmc\sdk\frameworks\mx\controls\DataGrid.as:1923] at mx.controls.listClasses::ListBase/set verticalScrollPosition() [C:\dev\flex_201_gmc\sdk\frameworks\mx\controls\listClasses\ListBase. as:1043] at mx.controls::DataGrid/mx.controls:DataGrid::scrollHandler ()[C:\dev\flex_201_gmc\sdk\frameworks\mx\controls\DataGrid.as:1720] at flash.events::EventDispatcher/flash.events:EventDispatcher::dispatchE ventFunction() at flash.events::EventDispatcher/dispatchEvent() at mx.core::UIComponent/dispatchEvent() [E:\dev\flex_201_borneo\sdk\frameworks\mx\core\UIComponent.as:8389] at mx.controls.scrollClasses::ScrollBar/http://www.adobe.com/2006/flex/m <http://www.adobe.com/2006/flex/m> x/internal::dispatchScrollEvent() [E:\dev\flex_201_borneo\sdk\frameworks\mx\controls\scrollClasses\Scro llBar.as:1096] at mx.controls.scrollClasses::ScrollThumb/mx.controls.scrollClasses:Scro llThumb::mouseMoveHandler() [C:\dev\flex_201_gmc\sdk\frameworks\mx\controls\scrollClasses\ScrollT humb.as:234] In my item renderer, I first removeAllChildren(), and I think this is what is causing this error. I just can't figure out why it only does it after I slide the slider up for the second time. I have been working on this for weeks now - it has taken an unbelievable amount of time and I still can't figure it out. Any help is VERY MUCH APPRICIATED!!! Thanks
