I'm starting coding with thymeleaf and also i'm not very advanced on HTML.
I'm setting up a webApp which manages a db. This has to add and modify three different entities.

The thing is that I want to make only one template for those three different forms. I think is not necessary to triplicate files since I can use some th:if tags. (I have to say that I'm an student and the notes the teacher gave us about thymeleaf are quite poor)

I have an index.html in which there is only 3 links redirecting to "../nuevo/P" ; "../nuevo/M" ; "../nuevo/E" .

Going into the controller, i have something like this:

@RequestMapping("/nuevo/dependencia")
public String enlace(@PathVariable(value="dependencia") char dependencia , Model model) 

 return "nuevoRegistro"; 

This goes into "nuevoRegistro" template...

<p th:text="'Nuevo '+ $dependencia" />
<div th:if="$dependencia == 'E'">
 <form action="/nuevo/E" method="post">
 <p>
 <b>Modelo:</b> <input type='text' name='modelo' />
 </p>

 <p>
 <b>Ano:</b> <input type='text' name='ano' />
 </p>
 /* some more fields 
 .
 .
 . */

 <input type='submit' value='Enviar' />
 </form>
</div>
<div th:if="$depencencia == 'M'">
 <p>M</p>
</div>
<div th:if="$depencencia.equals('P')"> //I was only trying new things here
 <p>P</p>
</div>

As far as I know, th:if does generate code if expression results true but im actually really confused with this $, @ ... tags and dont know very well how to use them as you can see.

I'm getting this error once i click any of the index links:

An error happened during template parsing (template: "class path
resource [templates/nuevoRegistro.html]")
org.thymeleaf.exceptions.TemplateInputException: An error happened
during template parsing (template: "class path resource
[templates/nuevoRegistro.html]")

and I suppose that the problem should be in the "th:if" statement.
What is wrong?
If I change the th:if statements maybe sometimes i get the "Nuevo + $dependencia" but im never getting the div I need.

Hope you can help me and thanks in advance!

  The thymeleaf docs and examples are actually pretty good. Just take a look.
