Compress Dom specific issues:
> Overview, Selection: Expanding plus node beside Canada can become unresponsive and take several clicks to register.
> Lazy Loading: Cities are unexpectedly loaded with a plus icon, expanding those nodes causes a class.java.lang.IndexOutOfBounds Exception.
See attached screen shot.
The city nodes are not supposed to be expandable. Expanding causes the exception.

To reproduce:
Build and deploy showcase with this addition to the web.xml file
    <context-param>
        <param-name>org.icefaces.compressDOM</param-name>
        <param-value>true</param-value>
    </context-param>

Issue 1 - ace:tree >Overview
Contract selections until Canada is the only remaining selection. Try clicking the plus node, it is unresponsive at times.

Issue 2 - ace:tree >Lazy Loading
Expand provincial nodes to reveal cities. Expand a city node, exception will occur. Note there city nodes should not be expandable.

This is a regression. The exception issue is not present with Icefaces P01, revision # 35307.
