My problem is that the sort direction icons are not displaying in the listheader. It seems like unless you set the ascending and descending comparators it doesn't include these, but since I have my own custom sorting method I don't want to include these. In my code sample, notice that I set the sort direction on both listheaders, but only the one with setSort="auto" displays any icons. Here is the sample:

<window title="Listbox" border="normal">
<listbox>
<listhead sizable="true">
<listheader label="Subject" sortDirection="ascending"/>
<listheader label="Received" sortDirection="ascending" sort="auto"/>
</listhead>
<listitem height="28px">
<listcell label="ZK Jet 0.8.0 is released" />
<listcell label="2008/11/17 17:41:29" />
</listitem>
<listitem height="28px">
<listcell label="URLs for iPhone-Optimized Google Sites" />
<listcell label="2008/11/17 15:56:37" />
</listitem>
<listitem height="28px">
<listcell label="Style Guide for ZK 3.5 released" />
<listcell label="2008/11/14 13:23:07" />
</listitem>
<listitem height="28px">
<listcell label="ZK Studio 0.9.0 released." />
<listcell label="2008/11/16 10:26:37" />
</listitem>
</listbox>
</window>

The second bug is what then i click on listheader it has only to state ascending and descending hasn't natural state
