null reference to working object TreeGrid #43

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
I'm having a strange error.  I define a treegrid object name tableDisplay3,
the object works, displays data, collapses and uncollapses just fine.  But
tableDisplay3 is a null reference.  I don't understand how the program can
fully load the object, and tableDisplay3 can still be a null reference. 
Can someone help?  thanks.

Here's the code where I declare the TreeGrid

<flexlib:TreeGrid 
    id="tableDisplay3"
    width="100%" height="100%" 
    dataProvider="{ dataObj }"
    paddingLeft="25"
    verticalTrunks="normal"
    rowHeight="30"
    showRoot="false"
    disclosureClosedIcon="@Embed(source='tree_openNode.png')"
    disclosureOpenIcon="@Embed(source='tree_closeNode.png')"
    folderClosedIcon="@Embed(source='status.png')"
    folderOpenIcon="@Embed(source='status.png')"
    iconField="@Embed(source='status.png'" >
    <flexlib:columns>
        <flexlib:TreeGridColumn dataField="name" />
        <mx:DataGridColumn dataField="desc" />
    </flexlib:columns>
</flexlib:TreeGrid>

This is the error I get after running Alert.show(String(tableDisplay3.id))

TypeError: Error #1009: Cannot access a property or method of a null object
reference.
