Hi All
I try to create a Textbox at window onCreate, and want to bind it.
But there are something wrong against my expect.

I use the zk demo site to describe my problem.
In the data binding sample code, I add the follow code on window and try to run it.

<attribute name="onCreate">
<![CDATA[
AnnotateDataBinder binder = (AnnotateDataBinder) self.getAttribute("binder", Component.COMPONENT_SCOPE);
Textbox nameTbox = new Textbox();
nameTbox.setParent(self);
binder.addBinding(nameTbox, "value", "selected.firstName");
binder.loadComponent(nameTbox);
]]>
</attribute>

Q1:
The new nameTbox can display name of first row.
But when I select other row, it's value not change.

Q2:
If I mark the follow tag in grid as comment, and run it again.

<!--
				<textbox value="@{selected.firstName}" />
-->

How cat I solve these problems ?
Thanks for your help.
