When you say you set selectedVlaue = null and it works fine, what do you mean by that? I don't see how it would change the selectedValue of an initialized set of RBs because the RGB tries to find the RB with the matching value and select it, and I'll bet none of RB's have a value of null.
Are you trying to unset all RBs? You might try setting RGB.selection = null, or maybe RGB.selection.selected = false; ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Tracy Spratt Sent: Wednesday, August 29, 2007 9:05 PM To: [email protected] Subject: [flexcomponents] ListItemRenderer,selectedValue assignment in commitProperties not "taking" My renderer is a modified copy of ListItemRenderer that adds some components, toggling their visibility based on the item data. Almost everything is working, except: One of the components is a RadioButtonGroup. In the commitProperties method, I look a the item data(XML) and get the value of a selectedValue attribute. If the atribute is null or empty, I set the RBG.selectedValue = null; This works fine, until I scroll. When I scroll, the recycled renderer gets the correct item, with a null/empty attribute, sets the selectedValue to null, but the selectedValue assignment does not "take". I test the value in the next line and it has the value from the previous item. Here are the snippets: override protected function commitProperties():void { trace("commitProperties()") super.commitProperties(); ... sTempValue = _data.attribute("selectedValue"); trace("...SETTING Item #" + [EMAIL PROTECTED]); trace(".....attribute value=" + sTempValue) if (sTempValue.length > 0) { trace("++++++ non-empty attribute value, setting selectedValue=" + sTempValue) rgbValue.selectedValue = sTempValue; } else { trace("------ null attribute value, setting selectedValue=NULL" ) rgbValue.selectedValue = null; } //now check the selecteedvalue if (rgbValue.selectedValue != null) { trace("......Check the selectedValue, item" + [EMAIL PROTECTED] + ".selectedValue=" + rgbValue.selectedValue); trace("") } And the trace for a true value item: ...SETTING Item #1 .....attribute value=P ++++++ non-empty attribute value, setting selectedValue=P ......Check the selectedValue, item1.selectedValue=P And the trace for a scrolled item: ...SETTING Item #28 .....attribute value= <===ATTRUBUTE IS EMPTY ------ null attribute value, setting selectedValue=NULL <===SETTING TO NULL ......Check the selectedValue, item28.selectedValue=P <===WTF? I'll attach the full IR as well. Thanks, Tracy <<LIR.txt>>
