How dynamic are these reports? And how many are there?
What about creating page fragments for each one and including the one
picked either with a jsp:include or a facelets ui:include?
If you really want to manually create components, the way to go about
it is to bind a panelGrour to your page, and then manually set up
everything with that binding getter.
You also MUST manually specific all required attributes (for example,
id) as part of this creation process.
However, I'd avoid creating components in java code if you can do so.
If it's just a matter of dynamically creating columns, use t:columns.

Thanks, Mike. I'm creating the components within the backing bean. Here is
how:
Jsp.~~~~~~~~~~~~~~~~~~
<f:view>
<h:form id="selectorForm">
<h:panelGrid footerClass="subtitle" headerClass=""
styleClass=""
columnClasses=""
binding="#{selector.panelGrid}">
Backing bean~~~~~~~~~~~~~
public HtmlPanelGrid getPanelGrid() {
grid = new HtmlPanelGrid();
grid.setColumns(4);
grid.setBgcolor("red");
HtmlSelectOneMenu chooser = new HtmlSelectOneMenu();
chooser.setId("reportsOfCategory");
chooser.setTitle("Please select a report to run");
chooser.getChildren().add(ReportsPerCategoryMapper.getOptionItems(this.getCategory().getName()));
grid.getChildren().add(chooser);
return grid;
}
What I don't know is how to make the backing bean build the rest of the
components after chooser passes it the report selected.
TIA.

It's unclear what part you need help with.
