Hi guys,
After some days i finally was able to get URL parameters in freemarker in the dashboards space.
And since I see some post about this topic i will want to provide my solution and maybe some expert can tell me if could be a good one.

First of all
We have to prepare the webscript, a really simple one.
-Go to CompanyHome /data directory / webscript extension. (in web-client)

Start with the xml descriptor file. Which tell what is the argument passed in this case value.
tabella.get.desc.xml


<webscript> 
      <shortname>ParametersGet</shortname> 
      <description>Passing Value Tabellone</description> 
      <url>/tabella?value={nameArgument}</url>  
   <transaction>required</transaction>
   <format default="html">extension</format>
   <authentication>user</authentication>  
</webscript>
‍‍‍‍‍‍‍‍‍‍

Next we have to prepare the view, also in this case a very simple one.
tabella.get.html.ftl


Hello, ${args.value}!
‍‍‍

tabella.get.html.ftl Inside this file you can put all your freemarker code.

Ok now the only things is to link this webscript into a jsp page.
(In my specific case the template is in the dashboard so you will have to follow all configuration steps.)

my jsp page is this.


<%@ taglib uri="/WEB-INF/repo.tld" prefix="r" %> 
<%– Note that this template is loaded from the classpath –%> 

<% 
String h = "0";
   String g = (String)request.getAttribute("cryms");
   if(request.getQueryString() != null){
       h = request.getQueryString().substring("value=".length(),request.getQueryString().length());
   }
      
 %>

<% String link = "alfresco/service/tabella?value="+h; %>

<r:webScript scriptUrl="<%=link%>"  />   
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

So the point is, before calling the webscript we get the parameters from the jsp page and we build the link for the web script.

—-
There is an issue, In the dashboard container because the dashlet are inside a form, and if you did not submit the form the script are not able to get the parameters.
My solution is to create a js function update the action of the form and then submit them.

Hope this help and sorry for my English, i m not a son of the Queen
