I don't understand, both questions seem to be about saving selected state, which Attila answered nicely. You can save and bind to the selected value as a page property.
Did I misunderstand, do you have another question?
Here's a working example from a page, which looks almost exactly like Attila's post:
the ui nodes:
<bc4j:rootAppModuleScope name="EmpAppModule" >
<contents>
<header text="Search" >
<contents>
<form name="search" >
<contents>
<inlineMessage prompt="Search" vAlign="middle" >
<contents>
<bc4j:viewObjectScope name="EmpView" >
<contents>
<flowLayout>
<contents>
<choice name="attrName"
data:selectedValue="attrName@ctrl:page"
shortDesc="Search Column">
<contents>
<bc4j:region automatic="true" >
<bc4j:attrStamp>
<option>
<boundAttribute name="text" >
<bc4j:attrDefProperty name="name" />
</boundAttribute>
<boundAttribute name="value" >
<bc4j:attrDefProperty name="name" />
</boundAttribute>
</option>
</bc4j:attrStamp>
</bc4j:region>
</contents>
</choice>
<textInput name="attrValue" columns="20"
data:text="attrValue@ctrl:page"
shortDesc="Search"/>
</contents>
</flowLayout>
</contents>
</bc4j:viewObjectScope>
</contents>
<end>
<submitButton text="Go" ctrl:event="search" />
</end>
</inlineMessage>
</contents>
</form>
</contents>
</header>
and the event handler
<event name="search" >
<!-- using the ApplicationModule causes it to be checked out from the
ApplicationPool. It is released using stateful mode. -->
<bc4j:findRootAppModule name="EmpAppModule" >
<!-- establish the ViewObject scope -->
<bc4j:findViewObject name="EmpView" >
<!-- search for the view criteria -->
<bc4j:findByExample>
<bc4j:exampleRow ignoreCase="true" >
<bc4j:exampleAttribute comparison="equals" >
<bc4j:nameBinding><bc4j:parameter name="attrName" /></bc4j:nameBinding>
<bc4j:valueBinding><bc4j:parameter name="attrValue" /></bc4j:valueBinding>
</bc4j:exampleAttribute>
</bc4j:exampleRow>
</bc4j:findByExample>
<bc4j:executeQuery/>
<!-- store the current search criteria as page properties -->
<bc4j:setPageProperty name="attrName" >
<bc4j:parameter name="attrName" />
</bc4j:setPageProperty>
<bc4j:setPageProperty name="attrValue" >
<bc4j:parameter name="attrValue" />
</bc4j:setPageProperty>
</bc4j:findViewObject>
</bc4j:findRootAppModule>
</event>
