Hello zk team

Updating to ZK 7 i discovered this bug:

Unable to make visible, again the first column of a listbox after resizing the last one.

With this test zul (based on the zk sandbox: 'Listbox controls with checkmarks'):

<zk>
<button label="Hide-Show" onClick="h.visible = !h.visible"/>
<listbox id="box" >
<listhead sizable="true">
<listheader id="h" label="Name"/>
<listheader label="Gender"/>
<listheader label="Age"/>
<listheader label="Description"/>
</listhead>
<listitem>
<listcell label="Mary"/>
<listcell label="FEMALE"/>
<listcell label="18"/>
<listcell label="A young lady."/>
</listitem>
<listitem>
<listcell label="John"/>
<listcell label="MALE"/>
<listcell label="20"/>
<listcell label="A college student."/>
</listitem>
<listitem>
<listcell label="Jane"/>
<listcell label="FEMALE"/>
<listcell label="32"/>
<listcell label="A remarkable artist."/>
</listitem>
<listitem>
<listcell label="Henry"/>
<listcell label="MALE"/>
<listcell label="29"/>
<listcell label="A graduate."/>
</listitem>
</listbox>
</zk>

Do this:

• Press 'Hide-Show', the first column hides
• Resize 'Age' column
• Press 'Hide-Show'. Now it's imposible to see the first column again!!!
