[flexcoders] Tree: Removing expand triangle from select nodes

[djdyland]

Hello,

I'm building a scripting reference app that is populated from an XML 
file. The structure is something like this.

<groupOfAssociatedClasses name="name of container">
   <class name="className">
      <property name="propertyName">
          <type>theType</type>
      </property>
      <method name="methodName">
          <inputType>type</inputType>
          <returnValue>value</returnValue>
      </method>
   </class>
   <class name="className">
      <property name="propertyName">
          <type>theType</type>
      </property>
      <method name="methodName">
          <inputType>type</inputType>
          <returnValue>value</returnValue>
      </method>
   </class>
</groupOfAssociatedClasses>
<groupOfAssociatedClasses name="name of container">
   <class name="className">
      <property name="propertyName">
          <type>theType</type>
      </property>
      <method name="methodName">
          <inputType>type</inputType>
          <returnValue>value</returnValue>
      </method>
   </class>
</groupOfAssociatedClasses>

I created a tree discriptor to filter out all the children on each 
class so it doesn't display them in the tree. All I want to see in 
the tree is the names of the containers and the names of the classes.

My proplem is that beucase the classes have children flex is 
displaying the expand node triangle beside the icon which ends up 
doing nothing becuase of the filter. How can I get rid of the expand 
node triangle?

I tried to turn it off but it ended up turning it off for the parent 
container nodes as well.

Any Help is much appreciated :)
