Wow finally got this working THANK YOU
EVERYBODY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Besides the syntax problems that you guys helped me with there was
another with the formatted xml data.
Since the code exists in a component the xmlns data was being (by
flex) inserted in the root of the xml data. So below:
Source:
<mx:XML format="e4x" id="myMenuData">
<root>
<menuitem id="menuDrill" label="Drill =>" >
<menuitem id="menuDown" label="Down" toggled="false"
enabled="true"/>
<menuitem id="menuUp" label="Up" toggled="false"
enabled="true"/>
</menuitem>
<menuitem type="separator"/>
<menuitem label="Lock / Unlock" type="check" toggled="false"/>
<menuitem type="separator"/>
<menuitem label="Reset Graph" toggled="false"/>
</root>
</mx:XML>
Trace:
<mx:XML format="e4x" id="myMenuData" xmlns="com.blah.blah.blah.*">
<root>
<menuitem id="menuDrill" label="Drill =>" >
<menuitem id="menuDown" label="Down" toggled="false"
enabled="true"/>
<menuitem id="menuUp" label="Up" toggled="false"
enabled="true"/>
</menuitem>
<menuitem type="separator"/>
<menuitem label="Lock / Unlock" type="check" toggled="false"/>
<menuitem type="separator"/>
<menuitem label="Reset Graph" toggled="false"/>
</root>
</mx:XML>
This is why I was getting a null when referencing it. The fix is to
put xmlns="" in the root and your examples worked.
Many Thanks!
