Dynamically created HTMLDataTable does not update its chlidren

Question

I have a very delicate problem that I hope to get help with. I have created a HTML data table dynamically in the Java code. The left-most column contains a checkbox so that I can select and deselect rows in the table. The problem is that the checkbox value is only read from my backing bean but changes to it are not written back.
The strange thing is that if I create exactly the same data table statically (i.e., as tags in the JSP-page) everything works perfectly fine.
Is there some strange property that needs to be set when creating the data table dynamically that the JSF-framework automatically sets when it creates the table from the tags?
Below you see the code for the creation:
HtmlDataTable component = new HtmlDataTable() ; 
CColumnHeader   column;
UIColumn        tableColumn;
tableColumn = new UIColumn();
HtmlOutputText textHeader = new HtmlOutputText() ;
textHeader.setValue("");
tableColumn.setHeader(textHeader);
HtmlSelectBooleanCheckbox tCheckBox = new HtmlSelectBooleanCheckbox() ;
tCheckBox.setValueBinding(  "value", FacesContext.getCurrentInstance().getApplication().createValueBinding("#{data.subItems[0].selected}")) ;                       
tableColumn.getChildren().add( tCheckBox ) ;
component.getChildren().addAll( this.uicolumns ) ;
JSF tag is defined as...
<h:dataTable id="table" value="#{bean.model}" binding="#{bean.component}" var="data" />This do not work!
However, the below code do...
<h:dataTable id="table2" value="#{bean.model}" var="data">
<h:column >
<f:facet name="header">
     <h:outputText value="" />
</f:facet>
<h:selectBooleanCheckbox value="#{data.subItems[0].selected}" />
</h:column>
</h:dataTable>          For what I know these to examples should be equivalent.
Furthermore, I noticed in the debugger that the attributes of my dynamically created table was not the same as the attributes on the one that JSF created for me. For example, each component that JSF created has got a map entry with the key javax.faces.webapp.COMPONENT_IDS for a ListArray containing the ids of its children. However if I try set this attribute in my code the column is not rendered at all. The UIColumn in the JSF-created table did have a javax.faces.webapp.FACET_NAMES=[header] in its attribute map. I don�t know if this has something to do with it, it was just one thing I noticed.
Is this a bug or am I missing something?

Answer 1

Why is that?
What is it that actually goes wrong here? The two example works
exactly the same in every aspect but in the first example, the JSF-
framework only calls the getter method of the selected property and the
latter case it calls both the getter and the setter. Otherwise the two
tables works correctly.
I use the binding attribute to be able to create the HtmlDataTable
before the actual page is loaded and dynamically populate it with
different numbers of columns depending on different system states.
This is the reason why I have to create it dynamically and why I have to
use the binding attribute.
What is the reason for this not working? Am I breaking anything in the
specification?
What do you mean by "...with the hope that JSF will draw.."? It's is
drawn, it is just the setter method that is not beeing invoked correctly.
