Ah nice idea, but I must be thick because I just can't get it to go.
I have the array/collection as:
public var file_prioritylist:Array = ["1", "2", "3", "4" ];
[Bindable]
public var file_priority:ArrayCollection = new
ArrayCollection(file_prioritylist);
I have the labelFunction as:
// priority labelFunction
public function priorityLabelFunc(item:Object):String {
return item.priority + "_teststring";
}
the datagrid is being populated by a remote dataprovider arraycollection which
contains the priority etc:
Bindable]
public var files_datagrid:ArrayCollection;
<mx:DataGrid id="fileDatagrid" x="0" y="0" width="715" height="130"
dataProvider="{files_datagrid}" change="putVideo()" selectedIndex="0">
and the column in question is laid out as:
<mx:DataGridColumn id="prioritycolumn" headerText="Priority" width="90"
dataField="priority" labelFunction="priorityLabelFunc">
<mx:itemRenderer>
<mx:Component>
<mx:ComboBox
dataProvider="{parentDocument.file_priority}" >
<mx:id>fileprioritycb</mx:id>
</mx:ComboBox>
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>
Which leads to a error of:
Argument count mismatch on Approval_System/priorityLabelFunc(). Expected 1, got
2.
if I edit it to move the labelfunction to the combobox and parentDocument it to
get to the function I get:
Cannot access a property or method of a null object reference.
I am sure I am just missing something simple so any insight appreciated
