Hey Alex, When I check the app in the debug version I get the following error on mousewheelscroll:
TypeError: Error #1010: A term is undefined and has no properties. at mx.controls.listClasses::ListBase/mx.controls.listClasses:ListBase::scro\ llVertically() [C:\dev\flex_201_ja\sdk\frameworks\mx\controls\listClasses\ListBase.as:5\ 358] at mx.controls.listClasses::ListBase/setverticalScrollPosition() [C:\dev\flex_201_ja\sdk\frameworks\mx\controls\listClasses\ListBase.as:1\ 043] at mx.controls.listClasses::ListBase/mx.controls.listClasses:ListBase::mous\ eWheelHandler() [C:\dev\flex_201_ja\sdk\frameworks\mx\controls\listClasses\ListBase.as:6\ 389] at mx.controls::List/mx.controls:List::mouseWheelHandler() [C:\dev\flex_201_ja\sdk\frameworks\mx\controls\List.as:2353] and this one when I use the scrollBar: TypeError: Error #1010: A term is undefined and has no properties. at mx.controls.listClasses::ListBase/mx.controls.listClasses:ListBase::scro\ llVertically() [C:\dev\flex_201_ja\sdk\frameworks\mx\controls\listClasses\ListBase.as:5\ 358] at mx.controls::List/mx.controls:List::scrollHandler() [C:\dev\flex_201_ja\sdk\frameworks\mx\controls\List.as:1257] at flash.events::EventDispatcher/flash.events:EventDispatcher::dispatchEven\ tFunction() at flash.events::EventDispatcher/dispatchEvent() at mx.core::UIComponent/dispatchEvent() [C:\dev\flex_201_ja\sdk\frameworks\mx\core\UIComponent.as:8324] at mx.controls.scrollClasses::ScrollBar/http://www.adobe.com/2006/flex/mx/i\ nternal::dispatchScrollEvent() [C:\dev\flex_201_ja\sdk\frameworks\mx\controls\scrollClasses\ScrollBar.a\ s:1096] at mx.controls.scrollClasses::ScrollThumb/mx.controls.scrollClasses:ScrollT\ humb::mouseMoveHandler() [C:\dev\flex_201_ja\sdk\frameworks\mx\controls\scrollClasses\ScrollThumb\ .as:234] The problem was like this before btw.. Different errors for different scroll methods but both point to the ScrollVertically method. I hope you can help me better now...:)
