Yeah, I thought invalidateList would clean that up for you. Somehow, rowInfo gets out of sync with listItems and things get messed up..

Getting error when change RowHeight and then Scroll Datagrid Hi Alex, I tried to use invalidateList() but it didn't worked out, I also tried out calling updateList() but it was also giving error when i change the fontsize again and again. finally i registered a upadateComplete event and wrote following and it worked. private function updateCompleteHandler(event:! FlexEvent):void{ while(rowInfo.length > listItems.length){ rowInfo.pop(); } } I don't know if this is correct or not but it is working for me. ----- Original Message ---- From: Alex Harui <[EMAIL PROTECTED]> To: flexcoders@yahoogroups.com Sent: Thursday, June 7, 2007 1:20:08 AM Subject: RE: [flexcoders] Help !!!

Getting error when change RowHeight and then Scroll Datagrid Hi All, I have a datagrid in which rowheight depends upon the fontSize. If i increase the fontSize rowheight increases and if i decrease the font size rowheight decreases. but at runtime when i change the fontsize , and scroll the grid i get error.I observed that when rowheight changes rowInfo is not updated like listItems. At this time rowInfo = 14 listItems = 10 TypeError: Error #1010: A term is undefined and has no properties. at mx.controls. listClasses: :ListBase/ mx.controls. listClasses: ListBase: :scrollVerticall y()[C:\dev\ flex_201_ gmc\sdk\framewor ks\mx\controls\ listClasses\ ListBase. as:5346] at mx.controls: :DataGrid/ mx.controls: DataGrid: :scrollVerticall y()[C:\dev\ flex_201_ gmc\sdk\framewor ks\mx\controls\ DataGr! id. as:1923] at mx.controls. listClasses: :ListBase/ set verticalScrollPosit ion()[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\framewor ks\mx\controls\ DataGrid. as:1720] at flash.events: :EventDispatcher /flash.events: EventDispatcher: :dispatchEventFu nction() at flash.events: :EventDispatcher /dispatchEvent( ) at mx.core::UIComponen t/dispatchEvent( )[C:\dev\ flex_201_ gmc\sdk\framewor ks\mx\core\ UIComponent. as:8323] at mx.controls. scrollClasses: :ScrollBar/h! ttp://www.adobe. com/2006/ flex/mx/internal ::dispatchScroll Event()[C: \dev\flex_ 201_gmc\sdk\ frameworks\ mx\controls\ scrollClasses\ ScrollBar. as:1096 <http://www.adobe.com/2006/flex/mx/internal::dispatchScrollEvent%28%29%5 BC:%5Cdev%5Cflex_201_gmc%5Csdk%5Cframeworks%5Cmx%5Ccontrols%5CscrollClas ses%5CScrollBar.as:1096> ] at mx.controls. scrollClasses: :ScrollBar/http://www.adobe. com/2006/ flex/mx/internal ::lineScroll( )[C:\dev\ flex_201_ gmc\sdk\framewor ks\mx\controls\ scrollClasses\ ScrollBar. as:1058 <http://www.adobe.com/2006/flex/mx/internal::lineScroll%28%29%5BC:%5Cdev %5Cflex_201_gmc%5Csdk%5Cframeworks%5Cmx%5Ccontrols%5CscrollClasses%5CScr ollBar.as:1058> ] at mx.controls. scrollClasses: :ScrollBar/ mx.controls. scrollClasses: ScrollBar: :downArrow_ buttonDownHandle r()[C:\dev\ flex_201_ gmc\sdk\framewor ks\mx\controls\ scrollClasses\ ScrollBar. as:1160] at flash.events: :EventDispatcher /flash.events: EventDispatcher: :dispatchEventFu nction() at flash.events: :EventDispatcher /dispatchEvent( ) at mx.core::UIComponen t/dispatchEvent( )[C:\dev\ flex_201_ gmc\sdk\fr! amewor ks\mx\core\ UIComponent. as:8323] at mx.controls: :Button/http://www.adobe. com/2006/ flex/mx/internal ::buttonPressed( )[C:\dev\ flex_201_ gmc\sdk\framewor ks\mx\controls\ Button.as: 1988 <http://www.adobe.com/2006/flex/mx/internal::buttonPressed%28%29%5BC:%5C dev%5Cflex_201_gmc%5Csdk%5Cframeworks%5Cmx%5Ccontrols%5CButton.as:1988> ] at mx.controls: :Button/mx. controls: Button::mouseDow nHandler( )[C:\dev\ flex_201_ gmc\sdk\framewor ks\mx\controls\ Button.as: 2234] ________________________________ Get the free Yahoo! toolbar <http://us.rd.yahoo.com/evt=48226/*http:/new.toolbar.yahoo.com/toolbar/f eatures/norton/index.php> and rest assured with the added security of spyware protection. ________________________________ Building a website is a piece of cake.
