Bad Ajax/JS init and behavior of the Template parameters form in Templating

In some cases the ajax refresh of the meta-widget for parameter is not correctly displayed.

Typically :

• Create a template with at least 2 parameters
• make the template parameters overridable
• create a document bound to this template
• edit the template parameter
• put one of the parameter as Documentproperty so that the checkbox loop is displayed
• then change the other parameter type
  => when using Boolean (in some cases), the Ajax rerender will fail with

  Caused by: java.lang.IllegalStateException: duplicate Id for a component params_edit_form:nxw_checkbox_1

Replacing the check box implementation for the looping from

<nxl:widgetType name="checkbox"

to

<h:selectBooleanCheckbox

seems to solve the issue.
