Re: Dynamic forms....

First of all, I don't think you can send multiple forms without
Javascript. Why do you want to have multiple forms? Anyway, you can
build such a page by creating a binding.

For example, I needed to build a form which had variable input fields.
The class I made looks like this:

public class DynamicForm {
     public HtmlPanelGrid getFormElements() {
         ReportInfo ri = (ReportInfo) ViewUtils.eval("#{reportInfo}");
         Set keys = ri.getParameters().keySet();

         HtmlPanelGrid grid = new HtmlPanelGrid();
         grid.setColumns(2);
         List children = grid.getChildren();

         Iterator ix = keys.iterator();

         while(ix.hasNext()){
             String next = (String) ix.next();

             HtmlOutputText ot = new HtmlOutputText();
             ot.setValue(next);
             children.add(ot);

             HtmlInputText hit = new HtmlInputText();
             hit.setSize(40);
             hit.setTitle(next);
             hit.setRequired(true);
             hit.setStyleClass("textfield");

             String bind = "#{reportInfo.parameters['" + next + "']}";
             hit.setValueBinding("value",
          ViewUtils.getApplication().createValueBinding(bind));

             children.add(hit);
             }

         return grid;
     }
}

Then I declard it in the grs-config.xml:

<managed-bean>
<managed-bean-name>dynamicForm</managed-bean-name>
<managed-bean-class>model.view.DynamicForm</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>

And used it in a JSF like this:

<h:panelGrid binding="#{dynamicForm.formElements}" />

I hope you can use this example to find a solution.
