Unable to view ComboBox inside AdvancedDataGridColumn

Question

Hello,
First I ahve to say that I am a beginner in Flex domain.
I am trying to show options in combobox inside an AdvancedDataGridColumn. In total I have two columns. One is a regular data column and the other is a ComboBox. I am able to see the first column but not the combobox one. Below is the code snippet.
I am not sure whats missing. Any help is really appreciated. I tried to lookup other examples but could not figureout whats missing.
<mx:AdvancedDataGrid 
id="assignmentDataGrid" alternatingItemColors="[#EEEEFF,#EEEEFF]" dataProvider="
{filteredAvailableReports}" width="100%" rowCount="10">
<mx:columns>
<mx:AdvancedDataGridColumn id="reportName" headerText="Report Name" dataField="
name" labelFunction="reportsListLabelFunction"/>
<mx:AdvancedDataGridColumn id="ftpConnCol" headerText="FTP Options" editable="true" editorDataField="value">
<mx:itemEditor>
<mx:Component>
<mx:ComboBox editable="true">
<mx:dataProvider>
<mx:ArrayCollection>
<mx:String>User1</mx:String>
<mx:String>User2</mx:String>
<mx:String>User3</mx:String>
<mx:String>User4</mx:String>
</mx:ArrayCollection>
</mx:dataProvider>

Check where you are generating to in your SSL properties. The chances are you are not generating to the SSL folder.
