In need of a good (simple) example and a wizard when I can dynamically update content

You can create a data utility which adds a JS code.

dropdown.addJsAction("onChange",
 "customJSMethod('" +
 tableId +
 "');");

Then you need be sure, that this js method is added in the wizard.

customJSMethod = function (tableId) {
 console.log("Refresh table " + tableId);
 PTC.jca.table.Utils.reload(tableId);
}  

 In this javascript you also could set a hidden text which can be read or whatever you need.

JCAappendFormHiddenInput(getMainForm(), 'fieldname', "value");

 In the table buildComponentData method you're able to read this hidden data to get the information you need.

Thanks @BjoernRueegg , I changed direction slightly to create a editable table of data (similar to multiobject rename). I am getting a strange jsp compilation issue on my wizard step JSP.. Here is the error message:

Page could not respond: /ptc1/signature/myObjectWizardStep

org.apache.jasper.JasperException: /netmarkets/jsp/signature/myObjectWizardStep.jsp (line: [20], column: [0]) Expecting "jsp:param" standard action with "name" and "value" attributes

and here is the wizard step code:

<%@ include file="/netmarkets/jsp/util/begin.jspf"%>
<%@ include file="/netmarkets/jsp/components/includeWizBean.jspf"%>

<%@ taglib uri="http://www.ptc.com/windchill/taglib/components" prefix="jca"%>
<%@ taglib uri="http://www.ptc.com/windchill/taglib/fmt" prefix="fmt"%>
<%@ taglib uri="http://www.ptc.com/windchill/taglib/objcomponents" prefix="objcomponent"%>
<%@ taglib tagdir="/WEB-INF/tags" prefix="tags"%>
<%@ taglib uri="http://www.ptc.com/windchill/taglib/mvc" prefix="mvc"%>



<jsp:include page="${mvc:getTypeBasedComponentURL('signatures.table')}" flush="true">
</jsp:include>

<%@ include file="/netmarkets/jsp/util/end.jspf"%>

I do have that text registered in mvc, a table builder class but I do not think that's an issue. Its not even compiling the JSP. Am I missing something?

I just wanted to follow up that I was able to get my wizard working. Without going into two many details, my wizard gets a number of related objects and displays their data in a table. I was able to have an input text field and drop down combobox on each line for each returned object. I have two validators assigned to disable or enable this action based on certain conditions which appears to work great. This was a great learning exercise, one that I think I made perhaps more complicated that it should be.  

I always have struggled with the customizer's guide. Looking back, you see all the tips and steps are there but reading it is like reading a book through a soda straw.  Many of the examples disappear as you navigate the layers or are very specific to the use case shown. I like watching the code flow from one thing to the next.  In any case, I might think about generalizing my example and posting it as it was a very great exercise.
